Echinoderm
|
Echinoderms are a successful phylum of marine animals. They include sea stars, brittle stars, sea urchins, sea cucumbers and their relatives.
Echinoderms have these features:
Echinoderms live in all parts of the ocean, but mostly on the sea floor. Some are filter feeders, and others (starfish) are important predators of molluscs and other shell-fish. They are extremely common near the shore, and on reefs.
They have a long and abundant fossil record. This phylum appeared in the early Cambrian period; it contains about 7,000 living and 13,000 extinct species. The four or five main groups are called sub-phyla by some authorities, and classes by others.
Echinodermata is the largest animal phylum which is entirely marine: no animals in this group live on land or in fresh or brackish water.
Taxonomy.
A simplified classification.
For many purposes it is better to use the following classification. It is easier to learn and understand, and is based more on the living forms.p19
Only with the crinoids is it necessary to deal with the fossil forms, because the stalked crinoids were so important on the Palaeozoic sea floors.
General account.
All echinoderms have fivefold radial symmetry in their body at some stage of life. The holothurians have bilateral symmetry as adults, and do not have so much of a skeleton as other groups.
Echinoderms have a hydraulic water vascular system. This network of fluid-filled canals moves and feeds the animal, and allows gas exchange. There is also a complete digestive tube. They have a simple radial nervous system that consists of a modified nerve net. There are nerve rings with radiating nerves around the mouth extending into each arm. The branches of these nerves coordinate the movements of the animal. Echinoderms have no brain, although some do have ganglia. They usually move with their tube feet, but brittle stars use their arms to pull against rocks. Some feather stars and sea cucumbers can swim.
The sexes are usually separate. Sexual reproduction typically consists of releasing eggs and sperm into the water, with fertilization taking place externally. Their larvae are planktonic.
Many echinoderms have remarkable powers of regeneration. A starfish arm cut off will regenerate. A section as small as a single arm, with some central disk and neural tissue, can regenerate the whole organism.
Echinoderm larvae.
Most of the adults have radial symmetry. If they are not sessile or attached, they are at least benthic (bottom-dwellers). In contrast, echinoderm larvae are planktonic, and have bilateral symmetry.p119 Echinoderm larvae are ciliated free-swimming organisms that have a bilaterally symmetry rather like embryonic chordates. The first stage in all groups except the crinoids is the dipleurula, which has a row of cilia winding round its body. All the groups have second and third stage larvae. The larvae grow, and are carried away from their parents.
Later, the adult body grows into a radial form, with the body arranged in five parts around a central axis. This means they often have a star-shaped pattern.
Evolution.
There is no geological evidence about the origin of echinoderms. The first undoubted fossils in the Lower Cambrian are already well developed, and fall into five or six different groups. "Arkarua", from the Ediacaran, is thought to be an echinoderm. "Tribrachidium" is another possible, from the same period. On general biological grounds, it seems that echinoderms, and some related phyla, may have been derived from worm-like ancestors.p311
Of all invertebrate phyla, the echinoderms are the closest relatives to the chordata, that is, animals who have spinal cord, such as vertebrates. With the chordates and hemichordates, echinoderms are deuterostomes, one of the two major divisions of the animal kingdom.

Das Rheingold
|
Das Rheingold ("The Rhinegold") is an opera by Richard Wagner. It is the first of the four operas that together tell a story called "Der Ring des Nibelungen" ("The Ring of the Nibelung").
"Das Rheingold" is an opera in one act, divided into four scenes. It is a very long act, lasting 2 ½ hours, but it is normally played without an interval as the music is continuous, even between the scenes.
The characters in the opera are Gods, Giants, Nibelungs and the Rhinedaughters. The Nibelungs are a race of dwarfs. They are cunning and evil and live underneath the surface of the earth.
The story of the opera.
Scene 1.
The first scene takes place in the river Rhine where the three Rhinemaidens: Woglinde, Wellgunde and Flosshilde, are guarding the precious Rhine gold. Alberich, an evil Nibelung dwarf, arrives and tries to catch the Rhinemaidens. From what they say Alberich learns that the gold they are guarding gives the person who owns it the power to rule the world. Alberich wants the gold, but the Rhinemaidens say that anyone who wants to have it has to renounce (give up) love. They think that Alberich will not do that because he is very fond of girls, but Alberich does renounce love and so he gets the gold.
Scene 2.
The second scene takes place in Valhalla, which is where the gods live. Wotan, the chief god, is there with his wife Fricka. Two giants have been building an enormous castle for the gods. Wotan has promised them that he would pay them for their work by giving them Freia, the Goddess of Youth and Beauty. Fricka is worried about the promise that Wotan has made, but Wotan tells his wife that he is not going to keep his promise. He thinks he can find a way of tricking the giants. Freia enters. She is frightened because the giants are coming for her.
The giants, Fasolt and Fafner, enter. They want to have Freia in payment for having built the castle. The problem for the gods is that Freia has a garden in which she grows golden apples. If the gods no longer have these golden apples they will grow old and die. Wotan does not know what to do.
Loge, the god of fire, enters. Wotan is cross with Loge for not having found something else to pay the giants with. Loge says he has been all over the world looking for something. He tells everyone that the gold from the Rhine has magic power, and how Alberich renounced love so that he could steal it from the Rhinemaidens. He tells them that a ring can be made from the gold, and that whoever has the ring will have power over all the world. The giants hear what Loge is saying and decide that they want the gold instead of Freia. They take Freia as hostage, saying that they will be back later to collect the gold. If they do not get it then they will keep Freia forever.
Wotan asks Loge how they are going to get the gold. Loge tells them that they should steal it from Alberich. After all, Alberich stole it from the Rhinemaidens, so it does not belong to him. Wotan and Loge go down below the earth to the Nibelungs.
Scene 3.
Underneath the earth Alberich is forcing the Nibelungs to work for him. They are hammering at the anvil. Mime, who is Alberich’s brother, has used some of the gold to make a helmet. This helmet is called the Tarn helmet. Anyone who wears it can change their shape or become invisible. Alberich treats his brother very cruelly.
Wotan and Loge tell Alberich that they have heard how clever he is. They ask him to show them what he can do with the Tarn helmet. Alberich puts on the helmet and changes himself into a huge dragon. Wotan and Loge pretend to be impressed. They ask him whether he can change himself into something small. Alberich show off again, changing himself into a frog. Wotan immediately puts his foot on him and catches him. Wotan and Loge take all the gold and go back to Valhalla.
Scene 4.
Wotan and Loge tease Alberich. Alberich asks them what they want so that he can be free. Wotan demands the gold. The Nibelungs pile the gold up. Alberich is not too worried, because he still has the ring which gives him magic power. He thinks he can use this power later to get the gold back. Wotan sees the ring on Alberich’s finger. He tells him to give him the ring. Alberich is terrified, but Wotan tears it from his finger. Before Alberich goes he puts a curse on the ring. Whoever has had the ring will die. This is very important to the whole story of the four operas.
The two giants appear with Freia. The gods have become very weak, but once Freia returns they start to become stronger again. Wotan tells the giants they can have their gold. The giants say that they must pile up the gold in front of Freia until they cannot see her. They do this, but the giants say there is still a tiny hole through which they can see Freia’s eye. They see the ring on Wotan’s finger and tell him to put it in the hole. Wotan says they can have anything they want but not the ring.
Erda appears. Erda is the Earth Goddess. She is very wise. She reminds Wotan that there is a curse on the ring and that he should quickly give the ring to the giants. Wotan has no choice. He puts the ring in the hole. Now the giants are happy.
Immediately, however, the giants start to argue with one another and Fafner kills Fasolt. The curse on the ring is working. Loge tells Wotan he was wise to give up the ring. However, Fricka is still worried because Wotan did have the ring.
Donner, the god of Thunder, enters and swings his hammer. There is a flash of lightning and a crash of thunder. The clouds vanish, a rainbow makes a bridge to Valhalla and the gods enter Valhalla. The Rhinemaidens are heard crying out to Wotan to give the gold back, but Wotan takes no notice. The gods are now at the height of their glory. We shall see, at the end of the fourth opera, that the curse will catch up with them and that they, too, will die.
The music.
The music of "Das Rheingold" is beautifully written to fit every person and every situation. The famous opening starts with a low chord of E flat which describes the bottom of the river Rhine. At first the notes of the chords are held on, then gradually a ripple of broken chords and arpeggios suggest the ripples of the water. The harps make a sound like the waves. The harmony just consists of the same E flat chord for the first 136 bars until the Rhine Maidens start to sing.
Each character in the opera has his own musical leitmotif which can change and combine to show their changing moods and situations. There are big, heavy chords for the giants, creepy chromatic winding music for Loge, the god of fire, who is supposed to be very crafty, dignified music for the Earth Goddess Erda etc. There is a special leitmotif for the curse, which is heard at various times in all four operas.
Wagner actually called "Das Rheingold" a "prologue" to the other three operas, which he saw as the main operas of the cycle.

Die Walküre
|
Die Walküre ("The Valkyrie") is an opera by Richard Wagner. It is the second of the four operas that together tell a story called "Der Ring des Nibelungen" ("The Ring of the Nibelung"). The story continues from the first opera which was called "Das Rheingold". It is a very beautiful piece.
"Die Walküre" was first performed on 26 June 1870 in Munich. The first performance that was part of the whole Ring cycle took place on 14 August 1876.
The story of the opera.
Act One.
The opera starts with a storm. The young man Siegmund is out in the storm and comes to a house. The house belongs to Hunding who lives there with his wife Sieglinde. An ash tree is growing in the middle of the house. Siegmund and Sieglinde are twins who were separated as children, so neither of them knows who the other one is. Their father is Wotan, the chief god, but they don’t know this either. Their mother was a mortal (an ordinary person, not a goddess) or perhaps a she-wolf, which is how the goddess Fricka refers to her.
Sieglinde lets Siegmund into the house and gives him a drink of mead. They start to fall in love. Hunding arrives and asks Siegmund who he is. Siegmund says that his name ought to be Woeful because he has had an unhappy life. When he was small he came home once and found his house burned down, his mother murdered and his twin sister had been abducted (taken away). He then remembers that some years later he went to help a young lady who had been forced to marry a cruel man. He had killed some of the man’s friends. Hunding realizes that he himself was this man, so that he is Siegmund’s enemy. He says to Siegmund that he can sleep in his house tonight because this is a law of hospitality, but in the morning he will have to fight him.
Sieglinde goes to prepare a drink for her husband. She puts a drug in it which will make Hunding sleep deeply. Siegmund meanwhile is thinking about something his father had promised him. He had told him that he would thrust a magic sword called “Nothung” into a tree. No one would get that sword until, one day, when Siegmund found himself in great difficulty, he would be able to pull it from the tree and use it.
Sieglinde enters and tells Siegmund a story about how, on the day she was forced to marry Hunding, an old man had come into the house and thrust a sword into the ash tree in the middle of the room. They start to realize that they are brother and sister, but it does not stop them from falling in love and they sing passionately about their love for one another. Siegmund pulls the sword from the tree and the two lovers embrace.
Act Two.
Wotan is the chief god, whom we heard in "Das Rheingold". He is trying to get rid of the curse of the Rheingold, and has built a grand plan around Siegmund. Wotan tells his daughter Brünnhilde that she must make sure that Siegmund wins the fight with Hunding. Brünnhilde (the out-of-wedlock daughter of Wotan and Erda, the Earth-Mother goddess) has the power to do this. She is one of eight daughters of Wotan who are Valkyries (German: Walküren). Their job is to collect the dead bodies of brave heroes who have died in battle and take them back to Valhalla, the house of the gods.
Wotan’s wife Fricka arrives in a chariot pulled by a ram. Brünnhilde disappears, and there follows a big argument between husband and wife. Fricka says to Wotan that Siegmund and Sieglinde must be punished for breaking Hunding's marriage, and for loving one another because brothers and sisters are not allowed to be lovers (this is called “incest”). She says that she herself is the goddess of marriage and must make sure that marriage laws are obeyed. Fricka says that the gods will all be disgraced. Wotan says that he went to the world to have children with mortal women because the gods needed a race of heroes who would protect them. But Fricka says to Wotan that he is wrong: Siegmund cannot be a free hero if he is being protected by Wotan. Giving in, Wotan now tells Brünnhilde that she must leave Siegmund to his fate.
Sieglinde tells Siegmund that she feels guilty and that he ought to leave her, but they are desperately in love. When she hears Hunding’s horn she imagines that Siegmund will be torn apart by the dogs and she faints. Brünnhilde pities Siegmund. She tells Siegmund that he must follow her to Valhalla. When Siegmund asks whether he can take Sieglinde with her Brünnhilde says that he cannot do this. Siegmund refuses to go. Brünnhilde tells him that he cannot escape his fate. Siegmund continues to plead with Brünnhilde, and in the end she is so moved that she changes her mind. She breaks Wotan's order, and says that she will protect Siegmund in battle. Hunding appears and the two men fight. Brünnhilde protects Siegmund with her shield. Siegmund is nearly winning when suddenly Wotan appears and smashes Siegmund’s sword into pieces. Hunding kills Siegmund.
Act Three.
The other Valkyries are wondering where Brünnhilde is. They see her coming on her horse, but instead of a hero she is carrying a woman (it is Sieglinde). The Valkyries are angry with Brünnhilde because she disobeyed Wotan. Sieglinde wants to die, but when she is told that she has a baby in her womb she asks Brünnhilde to save her. She escapes into the forest with bits of Siegmund’s sword. One day the baby she is now bearing will grow up, become a hero, and use the bits to make another sword.
Wotan goes to the Valkyries. He is furious with Brünnhilde because she disobeyed him. He punishes her. He tells her that she is no longer a Valkyrie. She will fall asleep on a rock and any man who finds her can have her. Brünnhilde pleads with Wotan. She asks him whether he could, at least, put a fire round her so that the only man who could get her would be a hero. In the end Wotan agrees. Loge, the god of fire, arrives and lights the fire. At the end of the opera Brünnhilde is asleep on the rock, surrounded by the fire. There she will stay until, one day, a hero comes to rescue her.
The music of the opera.
The music contains many wonderful moments. The most famous bit is the beginning of Act Three where the Valkyries are riding on their horses. This music is known as "The Ride of the Valkyries". It is very dramatic music. The very beginning of Act One is also very dramatic. The music describes a storm. The orchestra is a very large one, including special tubas which are known as “Wagner tubas”. There are no separate arias in these operas: all the sections flows into one another. Sometimes a character has a section when they are telling a story. There are beautiful sections like the one in Act One where Siegmund is remembering about his father and the sword, or the love music between Siegmund and Sieglinde. By using leitmotifs (music which goes with certain ideas or characters) he gets many subtle effects. When Siegmund looks at the ash tree we hear the sword motive because the sword is in the tree, although at that moment he does not know about it. We also hear Wotan’s theme when Siegmund talks about his father. We (the listener) know who his father is, but Siegmund does not. The music tells us lots of things that the characters in the story may not understand. This makes the music very powerful and exciting.

Siegfried (opera)
|
Siegfried is an opera by Richard Wagner. It is the third of the four operas that together tell a story called "Der Ring des Nibelungen" ("The Ring of the Nibelung"). The story continues from the end of the second opera which was called "Die Walküre".
The first performance of "Siegfried" took place when the whole Ring cycle (all four operas) were performed in the Festspielhaus in Bayreuth on 16 August 1876.
The story of the opera.
Act One.
The first part of the opera takes place in a forest where the giant Fafner lives. He has used the magic tarn helmet to change himself into a dragon so that he can guard the treasure of the gold and the ring (we saw how he got the treasure in the first opera, "Das Rheingold"). Siegfried, who was not yet born at the end of the second opera, "Die Walküre", is now a young lad. He has been brought up by the dwarf Mime, Alberich's brother. Mime is just as horrible as his brother.
Mime is hammering away at the anvil, trying to repair the sword that was smashed to pieces by Wotan in Act Two of "Die Walküre". He wants to make the bits into a strong sword, but every time he thinks he has managed it Siegfried picks up the sword and breaks it with his strength. The reason that Mime wants to make the sword is so that he can give it to Siegfried (who is obviously the hero who is meant to have the sword in the end) and tell him to fight the dragon. Then Mime will be able to get the ring from him so that he can have power over all the world. When Siegfried enters he brings a bear from the forest. The bear chases Mime and Siegfried laughs. Then he lets the bear go free.
Mime says to Siegfried that he should be thankful to him for looking after him as a child and bringing him up. He has never told Siegfried who his parents were (they were Siegmund and Sieglinde, both now dead). Siegfried does not understand anything about how babies are born. He has never seen a woman before. He only knows Mime who is pretending to be his father. Siegfried has noticed that young birds look like their parents and he asks Mime why he does not look like him. In the end Mime is forced to tell Siegfried about his parents and about the sword that was smashed by Wotan. Siegfried tells Mime to forge (make) the sword so that he can kill the dragon. Siegfried goes off.
Wotan, the chief god, appears. He is disguised as a wanderer. Mime says he wants to ask him three questions, and if he cannot answer them he can chop off his head. Wotan agrees. First Mime asks him the name of the race of people who live below the earth. Wotan says they are the Nibelungs. Then Mime asks who are the people who live on the earth’s surface. Wotan says they are the giants. Then he asks him who lives in the sky. Wotan says they are the gods. He has answered all three questions correctly. He now tells Mime it is his turn to ask Mime three questions which he must answer if he wants to keep his head. Mime is terrified, but has to agree.
First Wotan asks him who are the people whom Wotan loves a lot although he has to be harsh with them. Mime answers: the Wälsung race. Then Wotan asks him the name of the sword that Wotan left for Siegfried. Mime answers: Nothung. Finally Wotan asks him who can put the pieces of the sword together. Mime is now terrified because he does not know the answer. Wotan tells him the answer: it is the person who does not know fear. He says to Mime that he can keep his head for the moment. He will leave it to the fearless person to chop it off later.
When Mime and Siegfried are together again, Mime tries to frighten Siegfried so that he knows what fear is. He tells him all about the huge dragon in the cave. "Does that not frighten you?" he asks him. "Not a bit" answers Siegfried, who likes the thought of fighting a dragon. Siegfried works at the anvil and starts to make the sword. Mime is thinking of how he will trick Siegfried after the dragon has been killed, so that he can get the sword and kill Siegfried. At last Siegfried manages to make the mighty sword. He calls out its name: "Nothung"! Then he crashes the sword down on the anvil which splits into two pieces.
Act Two.
Outside the dragon’s cave Wotan, still disguised as a wanderer, meets Alberich (Mime’s brother who has not been in the story since the first opera). Alberich hates Wotan for having snatched the ring from him. Wotan does not care, and even wakes the dragon up, but the dragon does not want to fight them.
Mime and Siegfried appear. Siegfried is not frightened at all. He just wants to know where the dragon’s heart is so that he can kill it. Mime leaves him alone. Siegfried sits down in the forest and thinks. He is glad to know now that the ugly Mime is not his father. He hears a bird singing and he tries to imitate the bird’s song with a pipe he has made from a reed. He blows his horn and the dragon appears. Siegfried plunges the sword into the dragon’s heart. Siegfried instinctively puts his hand in the dragon’s mouth and tastes its blood. Suddenly he can understand what the bird is saying. The bird (originally sung by a boy but normally now by a woman) tells him to take the ring and the tarn helmet (which allows the wearer to change shape or make himself invisible). He takes them.
Mime and Alberich appear. They are arguing about who shall have the ring and the tarn helmet. Siegfried appears with both. Mime offers Siegfried a drink which is drugged. The bird warns Siegfried not to drink it. Siegfried kills Mime by chopping his head off with the sword. The bird then tells Siegfried about his beautiful bride Brünnhilde who is lying on a rock, protected by fire, waiting to be rescued by him.
Act Three.
Erda, the wise Earth Goddess, tells Wotan about the Norns who are weaving the rope of destiny. She is surprised to hear how Wotan has punished Brünnhilde. Wotan says he now looks forward to the end of the gods, and wants Siegfried to take his place.
Siegfried arrives. He tells Wotan (who is a stranger to him) about his heroic deed with the dragon. He finds Wotan annoying and smashes Wotan’s sword. He goes to the rock where Brünnhilde is lying.
Siegfried bursts through the flames and finds the sleeping Brünnhilde. He gently takes off her helmet, then her breastplate. Suddenly he sees that she is a woman. He has never seen a woman before. For the first time in his life he is frightened, yet he very much wants to wake her up. He kisses her lips and she opens her eyes and sits up. She tells him that she has always loved him, even long before he was born. Siegfried feels his passion growing and tries to put his arms round her, but now it is Brünnhilde who is frightened. She tells him not to spoil the purity of their love. Finally they embrace.
The music.
It took Wagner more than 15 years to write this opera which is one reason why the music of Act Three is slightly different in style. Some ideas from the love music of Siegfried and Brünnhilde were later re-used by Wagner in a separate orchestral piece, called the "Siegfried Idyll". Many of the leitmotifs (musical ideas that belong to particular characters or ideas) are ones that were heard in the "Das Rheingold" or "Die Walküre". One unusual instrument in the orchestra is the anvil. It is played when Mime, and later Siegfried, are hammering on the anvil trying to forge the pieces of the sword together. The rhythm of this music is the same rhythm heard earlier in the Nibelung scene in "Das Rheingold".
When Wagner started working on the opera he called it "Der junge Siegfried" ("The young Siegfried") but by 1856 he had changed the title to "Siegfried".
The German word “Sieg” means “victory” and “Fried” or “Friede” means “peace”. It is a good name for a hero. The role of Siegfried is sung by a tenor. The singer needs a very strong voice, often called a “Heldentenor” in German (a “heroic tenor”). He is on stage for most of the opera which lasts about four hours.

Götterdämmerung
|
Götterdämmerung is an opera by Richard Wagner. It is the fourth and last of the cycle of operas that together tell a story called "Der Ring des Nibelungen" ("The Ring of the Nibelung"). The story continues from the end of the third opera which was called "Siegfried". "Götterdämmerung" is the German name for "Ragnarök".
"Götterdämmerung" is the longest of the four operas. It takes about five hours to perform. It consists of a prologue and three acts. Wagner finished composing the opera in the autumn of 1874. It was first performed on 17 August 1876 as part of the complete Ring cycle.
The story of the opera.
The Prologue.
The three Norns, daughters of Erda the Earth Goddess, are spinning the rope of destiny. This rope is a symbol of what has to happen in the end. They take it in turns to tell the story of the past, spinning as they sing and passing on the rope to the next one. The first Norn tells how Wotan went to drink from the Well of Wisdom for which he lost an eye. He then cut a spear from a tree which then died. The second Norn tells how a young hero broke Wotan’s spear and how the gods were sent from Valhalla to chop down the World Ash. The third Norn tells how the logs from the ash tree have been piled round Valhalla ready for a fire that will burn everything. The Norns have visions of the future. The rope breaks. The Norns disappear into the earth.
Brünnhilde and Siegfried come out of a cave by the rock where they were left at the end of the third opera. Siegfried has to go off to do heroic deeds. He gives Brünnhilde the ring as a token of his love for her. She gives him her horse which is called Grane (pronounce: GRAH-ne). Siegfried travels down the river Rhine.
Act One.
Act One takes place in the Hall of the Gibichung palace. Gunther is the chief of the Gibichungs. His half-brother Hagen tells him he would look more important if he got married. He also says that Gunther’s sister Gutrune ought to get married. He tells him about Brünnhilde who, he thinks, is still asleep on the rock surrounded by fire that no one except Siegfried would be able to get through. He says that if they manage to get Siegfried to marry Gutrune, then she could persuade him to go and catch Brünnhilde for Gunther. He says that they could give Siegfried a potion (a special drink) which would make him forget that he loved Brünnhilde.
They hear Siegfried’s horn outside and the great hero arrives. Siegfried asks Hagen whether he knows him. Of course, Hagen does. Siegfried is carrying the magic tarn helmet which allows a person to change their shape or become invisible. Siegfried, however, does not know what the tarn helmet can do, and Hagen has to explain it to him. Gutrune appears and offers Siegfried a drink. It is the potion which is going to make him forget any other woman. He drinks to the health of Brünnhilde. As soon as he has drunk it he looks at Gutrune and is in love with her. He agrees to marry her, and he agrees to get a wife for Gunther. Hagen tells him about Brünnhilde on the rock. Siegfried has forgotten about her. He agrees to put on the tarn helmet and disguise himself as Gunther and to go and get Brünnhilde. He goes off, leaving Hagen guarding the palace.
The next scene takes place on the top of the Valkyrie rock. Her sister Waltraute arrives on a flying horse. She says that Wotan (their father, the chief God) returned to Valhalla with his spear broken. She says he told the gods to pile up the logs from the World Ash for a fire which will burn everything. Wotan desperately wants the ring to be given back to the Rhine Maidens (who were guardians of the gold, from which the ring was forged, in the first opera). Brünnhilde refuses to give her the ring that Siegfried had given her as a token of their love. Waltraute disappears.
After the weather calms the flames flicker again. Siegfried arrives, disguised as Gunther. Brünnhilde is horrified to see a person she thinks is a stranger. Siegfried says she is his bride, forces the ring from her finger and drags her into a cave for the night, although placing the sword between them.
Act Two.
Back at the palace Alberich tries to persuade his son Hagen to get the ring. Hagen wants to get the ring, but only for himself. Siegfried arrives. He no longer wears the tarn helmet so he looks like himself. Hagen blows his horn to call his vassals (soldiers) for a celebration. Gunther is to marry Brünnhilde and Siegfried is to marry Gutrune. Brünnhilde cannot understand why Siegfried is doing this. She sees the ring on his finger and asks him how he got it, as she thinks Gunther snatched it from her. Siegfried says that he won it by killing a dragon. He tells people how he tricked Brünnhilde and swears that a sword lay between them during the night, although Brünnhilde tries to make people think otherwise.
Brünnhilde is left alone with Gunther and Hagen. She tells them that, although Siegfried is so strong and impossible to kill in battle, he has one weak spot on his back. Gunther does not like the idea of having Siegfried killed, but Hagen promises him that he can then have the ring. They decide to kill Siegfried and to tell Gutrune that he was killed by a wild boar.
Act Three.
The last act takes place in a wild forest. Siegfried’s hunting horn is heard, and then the hunting horn of the Gibichungs. By the river Siegfried happens to meet the Rhine Maidens and teases them by showing them the ring, but does not let them have it. They tell him about the curse on the ring but Siegfried does not believe them. He meets Hagen. They drink together. Siegfried tells the men all about his life, how he was brought up by Mime, about the sword, the dragon and the bird singing. Then he cannot remember any more. Hagen gives him another drugged drink which makes him start to remember what actually happened. He remembers Brünnhilde and how he found her surrounded by fire. He gradually realizes how he has been tricked and feels unbearable sadness. Two ravens fly overhead and Hagen plunges his spear into Siegfried’s back. He dies while speaking the name of Brünnhilde. His body is carried off to a funeral march.
Back at the palace his body is brought in. Gutrune accuses Gunther of murdering him, but Gunther says Hagen did it. Hagen says he did it because Siegfried, when disguised as Gunther, had slept with Brünnhilde. He tries to snatch the ring from the dead Siegfried’s finger, Gunther tries to stop him but is murdered by Hagen. He tries again to snatch the ring but to everybody’s horror the arm of the dead hero rises in the air.
Brünnhilde enters and tells everyone how she promised Siegfried her love. Gutrune curses Hagen and falls onto her brother’s dead body. Brünnhilde orders a funeral pyre (a fire) to be prepared. She sings to Wotan that Siegfried is now at peace in death and that she understands more now. She takes the ring and promises to return it to the Rhine Maidens. She lights the fire which flares up and she rides on her horse Grane into the flames. The whole building catches fire, and the Rhine overflows and puts it out. Hagen jumps into the water trying to get the ring from the Rhine Maidens who drown him and finally take it back. The flood dies down and Valhalla (the gods’ palace) is lit up by the fire. The gods and the heroes die in the flames. The Twilight of the Gods has happened and Brünnhilde has redeemed the world with her love.
The music.
The music of this long opera is extremely cleverly linked so that musical ideas flow into one another and combine to comment on the drama. Many of the themes have been heard in the other three operas. It is a very exhausting opera to sing, especially for Brünnhilde. There are usually two long intervals during a performance. The orchestra is very large and includes eight harps.

Der Ring des Nibelungen
|
Der Ring des Nibelungen ("The Ring of the Nibelung" (Alberich)) is a cycle of four operas by Richard Wagner.
Titles.
The names of the four operas from the cycle are as follows, and in this succession:
"Das Rheingold," "Die Walküre," "Siegfried and" "Götterdämmerung".
The plot (storyline) of each opera can be found in the individual sections of this article. Wagner drew for the opera librettos on a collection of Germanic and Scandinavian legends, called "Nibelungenlied" (the "Song of the Nibelungs"), dating back to the 12th century and consisting of texts, composed by anonymous ancient poets and song performers, known in Germano-Scandinavian tradition as "scalds". The story deals with the ancient gods from Germano-Scandinavian mythology.
Composition.
Wagner made a lot of changes to the story in order to make it suitable for his four operas. Wagner’s story tells of a hoard of gold which is being guarded by the Rhinemaidens. The dwarf Alberich steals the gold and uses some of it to make a ring which makes the owner powerful over all the world. When Wotan, the chief god, steals it from him, Alberich puts a curse on the ring. The ring will bring death to whoever has it. The ring goes through the hands of several characters, all of whom die in the end.
Alberich belongs to a race of dwarfs called the “Nibelungs”. The word “Nibelungen” in the title of the cycle: "Der Ring des Nibelungen" (“The Ring of the Nibelung”), refers to Alberich (it is singular, not plural).
The story of Wagner’s Ring cycle sounds quite fantastic and strange, like a fairy tale. Although the characters seems very different from real people, the story tells us all about basic human emotions. It is a story about greed, love, lust, intrigue etc. This is what makes it so powerful.
Wagner’s music matches each character and situation beautifully. It develops continuously: there are no breaks in the music during the acts. Wagner used what he called leitmotifs (leading motives). These are tunes or chords or little musical phrases which are linked to particular people in the opera. In this way he can hint at things very cleverly in the music. For example: there is a leitmotiv for the curse. Whenever we hear this curse motive we know that the curse of the ring is working.
Wagner spent about twenty years writing the Ring cycle. He started in the 1850s when he was living in Switzerland. He wrote all the libretto (the words) himself, as he always did for his operas. By 1857 he had finished the first two operas and two thirds of "Siegfried". It was many years later that he finally finished "Siegfried" and wrote the final opera as well.
Opera house.
Wagner wanted to have the Ring cycle performed in a special opera house which would be built in the way he wanted. He needed a lot of money for his ideas, and he was very lucky to find someone who adored his music and was happy to give him a lot of money. This was King Ludwig II of Bavaria (sometimes called the “mad king of Bavaria” because he did become insane). Wagner told the King that the Ring cycle would be performed in Munich which was the capital city of Bavaria. Later, when it seemed impossible to build a new opera house there, Wagner broke his promise and built his opera house in Bayreuth instead. The King did not seem to mind and still gave him lots of money for the project as well as a nice house to live in. "Das Rheingold" was first performed in Munich in 1869 and "Die Walküre" in 1870. The whole Ring cycle was first performed in 1876 in the new opera house called the "Festspielhaus" in Bayreuth.

Väki
|
In Finnish mythology, Väki means races of Haltijas (Finnish elves) and their magical powers. Different things in nature had their own väki guarding them. For example, Väki of water lived in and protected water. Väki is the name of both the magical power and Haltijas'. Väki could sometimes be seen and they looked like little man-like creatures. Sometimes Väki went inside people and made people ill. Väki made people ill if they behaved badly in their kingdom. For example, if someone shouted in a forest without reason then the Väki of forest may make then ill. Shaman could heal these illnesses by telling the Väki to leave the person and go back to its original place.
The other version of Väki refers to the realm of the dead. Väki was the anonymous pack of dead people. The Väki had once being their beloved ones and relatives, but after spending some time in the afterlife, they all became unknown masses of dead creatures without any personal markings.

Sudetenland
|
The Sudetenland was a mountainous area of Czechoslovakia. The name comes from the Sudetes, a mountain range, but it was also used for other places in Bohemia in which mostly-German people lived. They wanted their homes to be part of Germany, not Czechoslovakia. Nazi Germany took small parts of the Sudetenland from Czechoslovakia in September 1938. After the Munich Agreement, they took the rest of Sudetenland, which contributed to the start of World War II.

Ochre
|
Ochre or Ocher is a golden-yellow or light yellowish brown colour. The word is from the Greek "ochros", meaning "yellow". Ochre is natural earth pigment containing hydrated iron oxide.
Meaning of ochre.
The use of ochre is particularly intensive: it is not unusual to find a layer of the cave floor impregnated with a purplish red to a depth of eight inches. The size of these ochre deposits raises a problem not yet solved. The colouring is so intense that practically all the loose ground seems to consist of ochre. One can imagine that the Aurignacians regularly painted their bodies red, dyed their animal skins, coated their weapons, and sprinkled the ground of their dwellings, and that a paste of ochre was used for decorative purposes in every phase of their domestic life. We must assume no less, if we are to account for the veritable mines of ochre on which some of them lived.

Patriotism
|
Patriotism means loyalty of a person to his/her own nation or the leaders of the nation. A patriot is a person who is on the side of his/her own nation or its leaders. Patriotism is different from nationalism.
Also, contrary to a nationalist, patriots do not favor imperialism, while nationalists tend to but don’t always favor imperialism. An example of a nationalist favoring imperialism would be Adolf Hitler.
The English term "patriot" is first known from the Elizabethan era, via Middle French from Late Latin (6th century) patriota "countryman", ultimately from Greek πατριώτης (patriōtēs) "countryman", from πατρίς (patris), "fatherland". The abstract noun patriotism appears in the early 18th century.

Misogyny
|
Misogyny is the hatred of women, or the belief that women should be kept down at a lower place in society, under the control of men. Using sexist ideas and violence against women, misogyny punishes women who try to rise in society. A society or a system that sets men above women is called patriarchy. Misogyny supports patriarchy by constantly keeping women under men. Sometimes misogyny rewards women for accepting a lower place.
Misogyny is a very old idea. It can be seen in stories, religion, laws, and customs around the world. It is both a belief held by individuals, and a social custom or system. A misogynist is a person, usually a male who hates women. Misogynists may hate women because they believe there is something wrong with them, such as being stupid, dirty or evil. Some misogynists claim to love women, or certain women, while keeping them at a lower place.
When women practice misogyny on themselves or each other, this is called "internalized misogyny". Women who have internalized misogyny may view other women as an enemy. This may damage friendships among women.
There are some communities that have been described as misogynist such as the manosphere.

Gómez Pereira
|
Gómez Pereira (1500 – 1567) was a Spanish philosopher, doctor, and humanist from Medina del Campo. He was most famous for his work in medicine, but he did many different things such as business, engineering, and especially philosophy. As a doctor, he was in favor of using the empirical method, instead of more medieval ideas about medicine.
His ideas in philosophy may have helped René Descartes come up with the famous idea "cogito ergo sum". This is Latin for: "I think, therefore I am".
Life.
Little is known about his life. He was the second of five brothers; his father, Antonio, had a small store that sold clothes, and his mother, Margarita, died when he was 15, so the children were raised by his aunt, Ana de Avila. Some of his ancestors were Jews from Portugal who had become Christians.
He studied philosophy at the University of Salamanca. His professor, Juan Martinez, was later the archbishop of Toledo, Spain. He also studied medicine and graduated in 1520. He then settled down as a doctor in his home town, Medina, living with his wife, Isabel Rodriguez, and becoming quite successful in business, even having his own warehouses of wine, and renting rooms to other merchants. He never had children.
He became famous as a doctor, being well known in other cities of Spain. He even went to the court of Philip II of Spain and saved the life of the prince, Don Carlos, when he had an accident. He was also famous as an inventor, and in 1563, he and another inventor named Francisco Lobato got a patent for a type of flour mill powered by water.

Spore (video game)
|
Spore is a computer game made by Will Wright. He also made "The Sims" and "SimCity". It consists of five phases of gameplay, the cell, creature, tribal, civilization and space phases. It is a game in which the player is able to create and evolve a species from a germ into a galactic superpower. It was released on September 7, 2008 in America, and September 5 in Europe.
Initially, it was going to be 6 different phases, but they merged the city and civilization phases, so it's only 5 phases now.
One of the biggest parts of the game is the different editors. Almost all things in the game can be made by the player, from buildings in the civilization phase to the creature in the creature phase. The player uses different parts that he can place as he wants. He can also change things like size and "stretch" the parts. All these things made by players can be uploaded as pictures to the "sporepedia". A picture has all the info needed for the game to make the thing, and is very small in size, usually less than 30 kilobytes. This means, that a player can find a picture of a car made in Spore that he likes, copy it, and put it in the Spore folder. Then they can play with it.
All the different phases of the game offer many choices. Roughly, the player can choose to be peaceful, aggressive, or both. For example, in the creature phase, there is a choice to eat other animals, just fruit, or both. And in the civilization phase, there is a choice to be military, religious, economic, or a little of all of them.

Tilia
|
Tilia is a genus of about 30 species of trees in the Northern Hemisphere, in Asia (where the greatest species diversity is found), Europe and eastern North America; it is absent from western North America.
The trees are generally called linden in North America, and lime in Britain. Both names are from the Germanic root "lind". The modern forms in English went from "linde" or "linne" in Anglo Saxon and old Norse, and in Britain the word transformed more recently to the modern British form "lime". In the United States, the modern German name "Linde", from the same root, became more common, partly to avoid confusion with any other uses of the name.
"Tilia" species are large deciduous trees, reaching typically between 20m and 40m tall, some species grow as shrubs. Plants of this genus are found through the north temperate regions.
History.
The Germanic tribes associated the Linden tree with the goddess Freya. Very often, these tribes held their assemblies, called Thing near or under such a tree. Often, trees that were standing alone somewhere were chosen. These assemblies were used to make laws. They usually lasted three days.
Uses.
The tree produces fragrant and nectar-producing flowers, the medicinal herb lime blossom. They are very important honey plants for beekeepers, producing a very pale but richly flavoured monofloral honey. The flowers are also used for herbal tea, and this infusion is particularly popular in Europe.

Cartesian coordinate system
|
In mathematics and geometry, the Cartesian coordinate system is a coordinate system used to give the location of points on a plane by using two numbers for each point. It is also called the "rectangular coordinate system". The numbers are usually called the formula_1 "coordinate" and the formula_2 "coordinate" or sometimes the "abscissa" and "ordinate". To find the coordinates of a point, two perpendicular lines, called "axes" (singular: "axis"), are drawn. The point where the axes meet is the coordinate origin, written (0,0). The formula_1 "coordinate" gives the position of a point measured along the formula_1 axis, and the formula_2 "coordinate" gives the position along the formula_2 axis. The coordinate system stretch's on to infinity in both "axes."
Cartesian coordinates can be used in three dimensions (3D), by adding a third number, the formula_7 "coordinate". In four dimensions (4D), a fourth number, the formula_8 "coordinate", is added. Each coordinate represents a dimension of space.
Using the Cartesian coordinate system, many shapes, like straight lines and parabolas can be described by using algebraic equations. The results of the equations can be seen by plotting (drawing) a point for each solution to the equations. For example, the formula_1 axis is described by the equation formula_10. A circle having radius formula_11 and centered at the origin can be described with the equation formula_12 (see Figure 2).
The name Cartesian comes from the French mathematician and philosopher René Descartes (Latin: "Cartesius"), who worked to merge algebra and Euclidean geometry. This work was important in creating calculus and cartography.
The idea of this system was developed in 1637 in two works by Descartes. In part two of his "Discourse on Method", Descartes explains plotting the position of a point or object on a surface, using two perpendicular axes as measuring guides. In "La Géométrie" ("Geometry"), he further explores these ideas.

Polar coordinate system
|
In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction.
The polar coordinate system is especially useful in situations where the relationship between two points is most easily expressed with angles and distance; in the more familiar Cartesian or rectangular coordinate system, such a relationship can only be found through trigonometric formulae.
As the coordinate system is two-dimensional, each point is determined by two polar coordinates: the radial coordinate and the angular coordinate. The radial coordinate (usually denoted as formula_1) denotes the point's distance from a central point known as the "pole" (equivalent to the "origin" in the Cartesian system). The angular coordinate (also known as the polar angle or the azimuth angle, and usually denoted by θ or formula_2) denotes the positive or anticlockwise (counterclockwise) angle required to reach the point from the 0° ray or "polar axis" (which is equivalent to the positive x-axis in the Cartesian coordinate plane).
History.
The concepts of angle and radius were already used by ancient peoples of the 1st millennium BCE. Hipparchus (190-120 BCE) created a table of chord functions giving the length of the chord for each angle, and there are references to his using polar coordinates in establishing stellar positions.
In "On Spirals," Archimedes describes the Archimedean spiral, a function whose radius depends on the angle. The Greek work, however, did not extend to a full coordinate system.
There are various accounts of the introduction of polar coordinates as part of a formal coordinate system. The full history of the subject is described in Harvard professor Julian Lowell Coolidge's "Origin of Polar Coordinates." Grégoire de Saint-Vincent and Bonaventura Cavalieri independently introduced the concepts in the mid-seventeenth century. Saint-Vincent wrote about them privately in 1625 and published his work in 1647, while Cavalieri published his in 1635 with a corrected version appearing in 1653. Cavalieri first used polar coordinates to solve a problem relating to the area within an Archimedean spiral. Blaise Pascal subsequently used polar coordinates to calculate the length of parabolic arcs.
In "Method of Fluxions" (written 1671, published 1736), Sir Isaac Newton examined the transformations between polar coordinates, which he referred to as the "Seventh Manner; For Spirals", and nine other coordinate systems. In the journal "Acta Eruditorum" (1691), Jacob Bernoulli used a system with a point on a line, called the "pole" and "polar axis" respectively. Coordinates were specified by the distance from the pole and the angle from the "polar axis". Bernoulli's work extended to finding the radius of curvature of curves expressed in these coordinates.
The actual term "polar coordinates" has been attributed to Gregorio Fontana and was used by 18th-century Italian writers. The term appeared in English in George Peacock's 1816 translation of Lacroix's "Differential and Integral Calculus". Alexis Clairaut was the first to think of polar coordinates in three dimensions, and Leonhard Euler was the first to actually develop them.
Converting between polar and Cartesian coordinates.
The polar coordinates "r" and "φ" can be converted to the Cartesian coordinates "x" and "y" by using the trigonometric functions sine and cosine:
The Cartesian coordinates "x" and "y" can be converted to polar coordinates "r" and "φ" with "r" ≥ 0 and "φ" in the interval (−, ] by:
Cylindrical coordinates.
Cylindrical coordinates take the same idea that polar coordinates use, but they extend it further. To get a third dimension, each point also has a "height" above the original coordinate system. Each point is uniquely identified by a distance to the origin, called "r" here, an angle, called "formula_5" ("phi"), and a height above the plane of the coordinate system, called "Z" in the picture.
Spherical coordinates.
The same idea as is used by polar coordinates can also be extended in a different way. Instead of using two distances, and one angle only, it is possible to use one distance only, and two angles, called formula_5 and formula_7 ("theta").

Singing
|
Singing means making music with the voice. Singing is probably the way that music started many thousands of years ago. When people sing they make their voices go high or low. If they do this in a way that uses notes of a scale then they make tunes, called songs. A song, very broadly, is a musical piece, produced by the voice with distinct and fixed pitches and patterns of sound and silence and a variety which often includes repetition. Many birds also sing. They are the passerines, a very large order often called the songbirds.
Techniques.
The voice uses the air in the lungs. The pressure of the air that comes out of the lungs can be controlled with several respiratory muscles, including the muscle called the diaphragm which goes across the front of the body below the ribs. People who have singing lessons spend a lot of time practising "breath control".
The air comes through the throat where the larynx is like a reed on a clarinet: it vibrates, controlling the passage of air, and this makes the note higher or lower depending on how it is controlled. The sound comes into the mouth which is space where the sound can be made bigger (it “resonates”). Professional singers even learn to think of the whole head as a resonator. They sometimes talk about the "mask", i.e. they imagine a mask in front of the face and this makes the sound bigger. The sound then comes out of the mouth so that it can be heard. Singing is different from speaking because of the special way the vocal cords in the throat are used.
Voice ranges.
Most people can sing notes which cover more than an octave. People who sing a lot will probably be able to sing over two octaves. Singers can be called according to whether they have higher or lower voices: soprano, mezzo-soprano and contralto for women, tenor, baritone or bass for men. Some men are able to train their voices to sing alto by using a falsetto voice. Children’s voices are often called treble.
Types.
Classical.
There are lots of different singing styles in the world. Each one has a different technique. In Western classical music, singers learn to sing in a bel canto voice which uses lots of resonance in the head and makes a smooth sound. Bel canto was used in Italian opera. Later, in the 19th century, Richard Wagner wrote operas in which the singers needed to be more dramatic. Opera singers today can have different kinds of voices: bel canto, lyrical, dramatic, coloratura (extremely high and light) etc. In church choirs the singers are often trained to use a lot of head voice because this sounds beautiful in large cathedrals.
Pop.
Pop singers generally have a different technique: Their singing is more from the throat. They do not need to develop powerful voices like opera singers because they sing into microphones so that their voices are electronically amplified. Voices singing music from different parts of the world may sound very different. Chinese singing sounds nasal (through the nose). In Mongolia there is a technique of overtone singing which sounds rather like a finger being rubbed against the rim of a wineglass. In Switzerland men often yodel. Rap is a kind of singing in which the rhythm is the most important thing. The pitch is high and low, but not to any particular notes. Scat singing is rather like rap.
A cappella.
A cappella singing is vocal music specifically without instrumental accompaniment. The name is from Latin "a" (without) and "cappella" (accompanied by muscial instruments). Cantata is a term that exclusively refers to accompanied singing, which is the exact opposite of Acappella.
Entertainment.
Singing is something that can be enjoyed by everybody. A group of people singing together is often called a choir. People can sing in choirs or smaller groups or on their own (solos). People can sing for their own enjoyment (e.g. in the shower), or they can practise hard and sing in concerts to an audience. Singing can be done alone ("a cappella") or it can be "accompanied", usually with musical instruments. Some people say they are "tone-deaf", meaning that they cannot sing in tune, but almost everybody can learn to sing if they try hard enough.

Amish
|
The Amish are a group of people who live according to the Anabaptist tradition. They have a common history with other Baptist movements, such as the Mennonites. The Amish are known for dressing plainly and living simply, without many conveniences of modern technology.
History.
The Amish church began in 1693 with a schism in Switzerland within a group of Swiss and Alsatian Anabaptists led by Jakob Ammann. Ammann's followers became known as Amish.
In the second half of the 19th century, the Amish divided into Old Order Amish and Amish Mennonites. During the 20th century, the Amish Mennonites assimilated into mainstream society, and accepted several of the conveniences modern technology has to offer. The Old Order Amish, on the other hand, kept much of their traditional culture. When people speak of Amish today, they usually mean the Old Order Amish.
There were other, smaller splits as well. At the end of the 20th century, there were about 18 bigger groups of Amish. Many of them emigrated to the United States.
Today, most Amish live in Pennsylvania (Lancaster County), Indiana and Ohio, in the United States. In Lancaster County, almost 25 percent of the Amish have the name Stoltzfus (or Stoltzfoos). Other common Amish names are Byler, Fisher, Petersheim, Lapp and King. In LaGrange, Indiana, most are named Borntrager, Miller or Schrock. In Adams County, Indiana, the names Graber, Grabill/Kraybill and Schwartz are common.
Lifestyle.
Many Amish people prefer simple lifestyles. They are usually farmers living in rural Amish communities. While their communities are separate from mainstream American society, Amish often live alongside non-Amish ("English") people.
Many groups, particularly Old Order Amish, forbid car ownership. From their perspective, owning a car is a way to stand out from the community, and the automatic mobility that cars provide weakens the sense of belonging together. However, riding in cars is not forbidden. In areas where there are many Amish, there are taxi services which will drive Amish people around.
Many Amish settlements are not connected to any electricity network. When they need electricity, they usually produce it themselves, often with diesel-powered engines.
Many Amish groups do not allow posing for photographs, because doing so makes a person stand out from others and is not humble. Often Amish people will turn their head down and to the side if someone aims a camera in their direction. They are usually less strict about an Amish person appearing on a photograph if they are not the subject of the picture.
Married men are not allowed to shave their beards or to have moustaches. Only unmarried men shave their faces.
The movie "Witness", starring Harrison Ford and Kelly McGillis, includes Amish characters.
Education and language.
Many Amish people who emigrated to the United States kept their language: a dialect of German called Pennsylvania German or Pennsylvania Dutch. As of 2012, there were between 350.000 and 420.000 speakers of Pennsylvania German in the United States.
Before the Second World War, Pennsylvania German was much more common and had around 800.000 speakers. However, during the war, people frowned upon German speakers, so many speakers did not teach the language to their children. Only conservative Baptists, such as Amish and Mennonites, withstood the pressure and still taught the language to their children.
After the Second World War, the Amish started to run their own schools, where they teach their children, how to read, write, and calculate. Very often, they also learn German so they can read religious texts. Amish schools do not teach biology or other natural sciences.

Horatio Nelson
|
Vice-Admiral Horatio Nelson (29 September 1758 – 21 October 1805) was an British sea captain in the Royal Navy.
Born at the rectory of the village of Burnham Thorpe, Norfolk, Nelson commanded the British fleet during the Napoleonic Wars, fighting the French and the Spanish. Nelson was blind in one eye after he had been wounded in battle.
During the Battle of Trafalgar, his greatest victory, he was killed by a French sniper.
Last words.
At least three versions of his last words exist and are shown in Wikiquote.
His most well-known last words are "Kiss me, Hardy".
Another statement during his last hours was "Thank God I have done my duty."
An alternative version is that he said both of those statements. He said "Kiss me, Hardy," When Hardy kissed him on the cheek. Then, Nelson said, "Now I am satisfied. Thank God I have done my duty." Next, Hardy kissed him again on the forehead, when Nelson called out, "Who is that?" Hardy replied, "It is Hardy." Nelson said, "God bless you, Hardy." Finally, he murmoured to those around him to look after Emma Hamilton and his daughter.
Most recently, accounts of his chaplain, Alexander Scott; his steward, Chevalier; and the purser, Walter Burke state that Nelson said, "Drink, drink. Fan, fan. Rub, rub." That was a request to ease the symptoms of thirst, heat, and the pains of his wounds.
Scott, who remained by Nelson as he died, recorded Nelson's last words as "God and my country."

Brain stem
|
The brainstem is the rear part of the brain. It has two sections: the hindbrain, which includes the pons and medula, and the midbrain.
Though the brainstem is small, it is extremely important. The motor (movement) and sensory connections from the main part of the brain to the rest of the body pass through the brain stem. Also, from the brainstem come the main motor and sensory nerves to the face and neck. These nerves are called the cranial nerves. The brainstem controls many bodily functions(called involuntary or unconscious) of which we are not normally aware, such as breathing, heart beat, and sweating. The brainstem controls functions which are unconscious, but necessary for life.
The hindbrain consists of the pons, and the medulla oblongata; which is an extension of the spinal cord. It connects the other parts of the brain (the cerebrum and cerebellum) to the spinal cord. Its neurons are the control centre of bodily functions, such as breathing and blood pressure.

Ideology
|
An ideology is a collection of ideas or beliefs shared by a group of people. It may be a connected set of ideas, or a style of thought, or a world-view. It was coined by a French philosopher, Destutt de Tracy in 1801/5.
There are two main types of ideologies: "political ideologies", and "epistemological ideologies". Political ideologies are sets of ethical ideas about how a country should be run. Epistemological ideologies are sets of ideas about the philosophy, the Universe, and how people should make decisions.
There are many different types of ideologies. Communism, socialism, and capitalism are political/economical ideologies.
Many political parties base their political action and program on an ideology. In social studies, a political ideology is a certain ethical set of values, principles, doctrines, myths, or symbols of a social movement, institution, or class which explains how society should work. It offers a political and cultural blueprint for a certain social order. A political ideology largely concerns itself with how to allocate power and to what ends it should be used. Some parties follow a certain ideology very closely, while others may take broad inspiration from a group of related ideologies without specifically embracing any one of them.
Political ideologies have two dimensions:
An ideology is a collection of ideas. Typically, each ideology contains certain ideas on what it considers to be the best form of government (e.g. democracy, theocracy, etc.), and the best economic system (e.g. capitalism, socialism, etc.). Sometimes the same word is used to identify both an ideology and one of its main ideas. For instance, "socialism" may refer to an economic system, or it may refer to an ideology which supports that economic system.
Ideologies also identify themselves by their position on the political spectrum (such as the left, the center or the right), though this is very often controversial. Finally, ideologies can be distinguished from political strategies (e.g. populism) and from single issues that a party may be built around (e.g. legalization of marijuana).
Today, many commentators claim that we are living in a post-ideological age, in which redemptive, all-encompassing ideologies have failed. This is often associated with Francis Fukuyama's writings on "the end of history".

Iran–Iraq War
|
The Iran–Iraq War was a war between the armed forces of Iraq and Iran lasting from September 1980 to August 1988. It began when Iraq invaded Iran on 22 September 1980, after a long history of border disputes and after Iran demanded the overthrow of Saddam Hussein's regime. Iraqi forces did well at the beginning of the war, taking Iranian Khuzestan province, but they were stopped and forced out of Iran before long. The war continued for years, and neither side gained much ground in the resulting trench warfare. About a million soldiers died, and a similar number of civilians. Both sides used blockade, which other countries opposed. Despite several calls for an end to the fighting by the United Nations Security Council, the two countries fought until 20 August 1988; the last prisoners of war were exchanged in 2003. The war changed politics in the Middle East and worldwide.
The Iran–Iraq War is also noted for Iraq's use of chemical weapons and biological weapons against Iranian troops and civilians. The role of the United States and Soviet Union was vital, dating back to the Cold War. In 1953, the US encouraged a coup d'état against Mohammad Mosaddegh, who was the Prime Minister of Iran. Shah Mohammad Reza Pahlavi returned to power, supporting his military and his government. The United States sold many weapons to the Shah's government. Meanwhile, revolutionaries of the Arab Socialist Ba'ath Party overthrew the king of Iraq and, with the help of the Soviet Union, built up their army. Starting with the United Arab Republic, they sought to unite all the Arabs into one state, including the Arab minority in Iran.
After the war started (especially between 1983 and 1988), the United States sold weapons to the Iraqis. This move was mainly due to America's interest in containing the revolutionary Ayatollah Khomeini. Thus, both the Soviet Union and the United States supplied Iraq with weapons against Iran. The United States had sold many weapons to Iran before the war. It was believed the Soviet Union was selling weapons to both sides during the war.
Background.
Situation in Iraq.
Ba'ath ideology and Iraqi demographics.
In the middle of the 20th century, the Ba'ath parties were ruling both in Syria and Iraq. The ideology behind Ba'athism is to unite the Arab regions and create a Pan-Arab state. The ideology is also oriented towards socialism. Although the Ba'ath ideology has nationalist roots and is not related to religion, Ba'ath leaders and politicians have often used religious outlets to gain popularity and support of the people. Although the Pan-Arab nationalism worked out in other Arab countries such as Egypt, this was a difficult case in Iraq. The reason for this, is the diversity of the Iraqi population. Because of the Sunni - Shi'a and Arab-Kurd divide, Iraq is seen as one of the most difficult countries to govern. It was especially difficult, as the Ba'ath party was dominantly Sunni, whereas the population of Iraq, the origin place of Shia Islam, is dominantly Shia (55%). The president of Iraq at the time, was Saddam Hussein, who took most of the power in his own hands and strived for strong Arab leadership. His ambitions to take the lead in the Arab world were also a key element for his later attack on Iran.
Shatt al-Arab.
The Shatt al-Arab waterway, bordering Iraq and Iran, is crucial to Iraq, because it is its only major outlet to the sea. The waterway is controlled by Iraq and has been a source of tension between the states long before the Iranian revolution. The main reason for tension around this waterway has been its function as a border. Because of this, it has been an issue between the Ottomans and Iran. After the fall of the Ottoman Empire, the waterway was controlled by Iraq. However, in 1969 Shah Reza refused to pay fees for Iranian ships passing the waterway. He also started backing up Kurdish separatists groups in Northern Iraq. To stop the support of Iran to the Kurds, Saddam signed the Algiers agreement in 1975. Iran stopped supporting the Kurds, and the border was placed in the middle of the waterway. One of the reasons, according to Saddam himself, for being pressured to sign this agreement was the military advancement of Iran during the rule of the Shah. Saddam withdrew the agreement several days before invading Iran, in September 1980, drawing upon the importance of the waterway. Before and during the war, Saddam was vocal about the right of Iraq to Shatt al-Arab as well as Khuzestan, the bordering Iranian region that is mainly inhabited by Iranian Arabs.
Threat of the Iranian revolution.
The Pan-Islamic nature of the new Iranian state was in contrast with the Arab nationalist context of Iraq. After the establishment of the Islamic Republic in Iran, the secular yet authoritarian rule of Hussein felt threatened. A large Persian state posed a threat against the Pan-Arab ideology of Hussein. The Shia Muslims in Iraq were already posing a threat to Saddam by protesting and mobilizing against the Ba'ath regime. This only became worse after the Iranian revolutionaries called upon Iraqis also to initiate a revolution. Other than these political threats, Iraq was in a more fragile position geographically.
Situation in Iran.
The Iranian revolution.
In Iran, the Pahlavi dynasty had been ruling since 1925, after the overthrow of the Qajar dynasty. The Pahlavi empire aimed to create a westernised and progressive Iranian state. The second and last monarch, Shah Mohammed Reza, started implementing bolder reforms that affected citizens' daily lives. As a reaction, opposition from all parts of society began growing. Especially clergymen were encouraging the people to stand up against westernization and strive for an Islamic state ruled by Islamic jurists. Khomeini was one of the leading clerics during the period of political tension. In 1977, these tensions led to large-scale demonstrations and eventually the exile of the Shah. In 1979, the Islamic Republic of Iran was officially established, headed by Ayatollah Khomeini. This sudden turn of events in Iran came as a surprise to most countries. The rise of a shia power caused concerns in several surrounding countries. Especially in Iraq, where the Shia majority was ruled by the Sunni minority. It was not only the rise to power of clerics that was concerning. Khomeini and his counterparts were also vocal about their desires to create Islamic states in the surrounding Muslim majority countries. The ultimate goal was to create a united Pan-Islamic state under Khomeini's rule.
Military power.
Shah Mohammed Reza had invested a lot into the modernization of the Iranian army. He was fully backed by the United States, as they supported the anti-communist stance of Iran and saw this as an opportunity to have a state that supported US interests in that region. Thus, the Shah expanded navy, air and ground forces with modern weapons and imported western trainers for the army. For this reason, Iran became more capable than Iraq, also taking into account the army officers that were almost twice as many in Iraq. However, the revolution changed this military upper hand drastically. The revolutionaries did not understand the need for extensive arming supplies and did not want to be the policeman of the US. Therefore, Khomeini and his reign immediately canceled military contracts and sent away the western trainers. Because of the sudden regime change, the morale of the officers also lowered significantly, according to Iraqi intelligence at the time. A parallel military force was created by Khomeini, as the previous officers were in danger of a potential counter-revolution. These factors caused Iran to remain with a limited military force.
The war.
Iraqi invasion.
Start of the invasion.
Iraq invaded Iran on September 22, 1980. Hussein was confident that the invasion would move swiftly, as the Iraqi army was well-equipped thanks to Saddam's investments in the military. Hussein also believed in a quick win due to intelligence reports stating that the Iranian army had been ineffective after the Iranian Revolution. It would later become clear that this invasion would benefit Khomeini by allowing him to eliminate his opposes and uniting his nation for national defense At the center of Iraq's objectives was the annexation of the East Bank of the Shaat Al-Arab waterway which had been the site of numerous border skirmishes between the two countries going back to the late 1960s. The president of Iraq, Saddam Hussein, also wanted to annex the Iranian province of Khuzestan, substantially populated by Iranian Arabs.
Offensive battles.
Iraq mobilized many aircraft to carry out air strikes on 15 cities and air bases in Iran, including the capital Tehran. Beginning in March 1982, Iranian forces shifted to the counter-offensive. On 29 June 1982, Iraq announced that it had withdrawn its forces from the occupied Iranian territory and the border between the two countries was restored to its pre-war status. Iranian defenses are focused on the northern front to block the main routes and delay the Iraqi army's advance. Iran blocked the momentum of the Iraqi offensive and gradually seized the initiative in the war. In September 1981, Iran launched a major counteroffensive. At the end of September, the Iraqi siege of Abadan was lifted with the launch of a major Abadan counter-offensive. On April 20, Iran again concentrated the forces of nearly three divisions, and a large number of revolutionary Guards, about 100,000, launched the "Jerusalem Al-Quds Operation" offensive to recover the city of Khorramshahr. After 25 days of fierce fighting, the city of Khorramshahr, an important port city in the south, was finally recaptured. On 10 June, Iraq proposed and unilaterally implemented a cease-fire, announced that it recognized the continued validity of the Algiers Agreement signed by the two countries in 1975, and was ready to negotiate with Iran based on the recognition of Iraq's fundamental rights.
1988 was the year when the Iran–Iraq War took a turning point. Between February and April, the two sides used hundreds of missiles to strike each other's towns, unleashing a "city assault" on an unprecedented scale.
Aftermath.
End of the war.
The War lasted for seven years and 11 months (from September 2, 1980, to August 20, 1988), and experienced four strategic stages: Iraq's attack, Iran's counter-attack, Iran-Iraq stalemate, and Iraq's counter-attack. The two sides were inflexible. Each demanded too high a price for a ceasefire. Iran's insistence on playing the long game was encouraged by its vast population and religious fanaticism.
The Iran–Iraq War was one of the longest wars of the 20th century. It was a veritable war of attrition, and a pyrrhic war with no victor. Before the war, Iraq had foreign exchange reserves of us $37 billion. At the end of the war, its foreign debt was over US$70 billion, of which over US$40 billion was arms debt owed to western countries and the Soviet Union, and US$30 billion was loans owed to other Arab countries.
Iraq suffered 180,000 deaths, 250,000 injuries, and $350 billion in direct losses (including military expenditures, war damage, and economic losses). Iran also owes $45 billion in foreign debt, has 350,000 deaths and more than 700,000 injuries, and 200,000 women in Tehran alone have lost their husbands; Direct losses of $300 billion. The war has set back the economic development plans of both countries by at least 20 to 30 years. The battle took a heavy toll on both countries, halting economic growth, plummeting oil exports, and killing millions. As a result, Iraq has also been saddled with a large debt, amounting to $14 billion for Kuwait alone. That was one of the reasons Saddam Hussein invaded Kuwait.
At the end of the war, the national border between the two countries was restored to the pre-war situation.
Postwar situation.
The mediation of the international community failed several times. Iran and Iraq did not accept the mediation of the United Nations until July 1988, and the formal armistice ended in August. From the perspective of international factors, the US and the Soviet Union's interference doomed the war to be inconclusive and protracted from the beginning, which restricted meaningful outcomes and caused unjustifiable long-lasting social and political problems.
The United States and the Soviet Union happened to have a similar position on the Iran–Iraq War: they both adopted the policy of neutrality and balance of power and tried to maintain the balance of power on both sides. They both wooed and suppressed Iran, but there were differences in tactics. Both Iraq and Iran are located in the Gulf region, which is extremely important in the global strategy of the United States and the Soviet Union. Although the United States and the Soviet Union declared neutral and not directly involved in the Gulf region, they grouped up with their allies. They took advantage of the opportunity of the war to step up the competition in the Gulf region and squeeze out each other for their own national benefit.
Other Facts.
The Iran–Iraq War is an international interpretation of this war, and it has various titles depending on the country. It is known, in Iran, as "the Iraqi Invasion", "the Holy War of Resistance", and "the Iranian Revolutionary War". In Iraq, it is known as "Saddam Hussein's Qadisyah". Essentially, the war was an eight-year direct military conflict between Iran and Iraq.
Both Iraq and Iran suffered heavy losses in the war. When the failed to make progress on the battlefield, they tried to destroy the enemy's logistics and economic facilities by attacking cities, ships, and oil fields. Many ships from other countries suffered casualties. As the Iran-Iraq ship attack affected the interests of non-belligerent countries, Kuwait, in November and December, 1986, the
United States, the Soviet Union, China, France, and the United Kingdom, the five permanent members of the United Nations, proposed to charter ships and escort requirements.

Lavender (color)
|
Lavender, a popular color, is a light tone of violet.
The name comes from the flower of the lavender plant. Originally, the name "lavender" only meant the color of this flower. The color of the flower is still the standard for lavender but there are many other tones of light or medium violet now called "lavender" also.
The color of the flower can also be called "floral lavender". Other shades of lavender can range in hue from pinkish purple through violet to blueish-indigo. They can also range from light and pale to medium and greyish shades.
By 1930, the book "A Dictionary of Color" identified three major tones of lavender--"[floral] lavender", "lavender gray", and "lavender blue", and in addition a fourth tone of lavender called "old lavender" (a dark lavender gray) (all four of these shades of lavender are shown below). By 1955, the "ISCC-NBS Dictionary of Color Names" listed dozens of different shades of lavender.
The first recorded use of the word "lavender" as a color term in English was in 1705.

Freedom fighter
|
A freedom fighter is a person who thinks their native ethnic group is not free, and is working to have freedom for their group. Most often this means that a freedom fighter wants their people to have own nation and independence and/or get rid of oppressors. People who think like this are said to think in a nationalist way.
Freedom fighter is a "relativistic" term - this means a person decides by his or her point of view if he call some persons or groups freedom fighters or not. Freedom fighter is a "positive" term - this means that he or she calls a person "freedom fighter" only if he or she supports the goals of the freedom fighter. If people do not support his goals, they probably use more "negative" terms like insurgent, terrorist, rebel or criminal.
Freedom fighters are often called terrorists by their opponents if they hurt civilians. However, not all freedom fighters hurt civilians. Some freedom fighters damage the opposing military. Some freedom fighters damage property - this is called sabotage. There are also freedom fighters who do not use violence at all. For example, Mahatma Gandhi and Dalai Lama.
Groups.
These are examples of groups who call themselves freedom fighters.
Other examples.
In public media.
•Assassin's Creed is based around a group of freedom fighters.
•The Hunger Games is set in a dystopia that later features freedom fighters.

Sepultura
|
Sepultura is a Brazillian heavy metal band formed in 1984. They are based out of Belo Horizonte. The group has sold over 15 million albums worldwide. The brothers Max and Igor Cavalera started it in Belo Horizonte in 1984. The two brothers have left the band since, Max in 1996, and Igor in 2006, with American singer Derrick Green and drummer Jean Dolabella replacing them after their exits, although Dolabella left in 2011 to be replaced with Eloy Casagrande.
History.
The band's name is Portuguese for the word "grave". The Cavalera brothers chose this name after translating English band Motorhead's song called "Dancing On Your Grave".
Singer Wagner Lamounier and bass player Paulo Jr. were the first stable members to join the band along the Cavaleras. Lamounier left after a year, and Max decided to sing and play guitar. The band added a second guitar player named Jairo Guedez. These members recorded their first album, "Morbid Visions", in 1986. The song "Troops of Doom" from this album gave the band some popularity.
Guedez left after the album was released, being replaced by Andreas Kisser. This line-up lasted until 1996 and did many things. They recorded five more albums from 1987 to 1996. Sepultura began to play music that sounded more like thrash metal than death or black metal for their next three albums: "Schizophrenia" (1987), "Beneath The Remains" (1989) and "Arise" (1991). Their next two albums sounded more like groove metal. They were named "Chaos A.D." (1993) and "Roots" (1996). Popular songs from "Chaos A.D." include "Refuse/Resist" and "Territory". On "Roots", they had a song they recorded with the Brazilian Xavantes tribe called Itsari, who also toured with them.
Conflicts between Max and the other members led to Max leaving the band. He was replaced with American singer Derrick Green. Although the band's album sales lowered with each album released with Green, he is still in the group. With Sepultura, Green has helped record the albums "Against" (1998), "Nation" (2001), "Roorback" (2003), "Dante XXI" (2006), "A-Lex" (2009) and "Kairos" (2011).
After Sepultura released "Dante XXI" in 2006"," Igor Cavalera left the band. A year later, he made up with his brother Max, and the two formed The Cavalera Conspiracy. Igor's first replacement in Sepultura was Jean Dolabella, who recorded "A-Lex" and "Kairos" with the band before quitting. The band's drummer today is Eloy Casagrande.

Dalai Lama
|
The Dalai Lama is a religious figure in Tibetan Buddhism. He is its highest spiritual teacher of the Gelugpa school. A new Dalai Lama is said to be the reborn old Dalai Lama. This line goes back to 1391. The 14th and current Dalai Lama is Tenzin Gyatso.
Between the 17th century and 1959, the Dalai Lama was the head of the Tibetan government. During the winter, the Dalai Lamas stayed in the Potala palace. In the summer they lived in the Norbulingka palace. These two palaces are both in Lhasa, Tibet. In 1959, the Dalai Lama had to escape from Tibet to Dharamsala, India. This is still his base to this day.
Dalai Lama is the title of the Tibetan Buddhism leader. "Dalai" is originally from Mongolian which means "ocean" and "Lama" is original from Tibetan which means "the highest principle". In 1653, during the Qing Dynasty, this title was authorized to Dalai Lama V by the Chinese Emperor for the first time.
Modern history.
The 13th Dalai Lama, Thubten Gyatso, expelled all Chinese civilians from the country, and instituted many measures to modernise Tibet. These included rules to curb excessive demands on peasants and tax evasion by the nobles. He set up an independent police force, abolished the death penalty, extended secular education, and brought electricity tto the city of Lhasa in the 1920s. Thubten Gyatso died in 1933.
The 14th Dalai Lama was not formally enthroned until 17 November 1950, during the People's Republic of China invasion of Tibet (1950–1951). Fearing for his life, he fled to India where he has led a government-in-exile since. With the aim of launching guerrilla operations against the Chinese, the Central Intelligence Agency funded the Dalai Lama $1.7 million a year in the 1960s. In 2001, he gave up his absolute power over the government to an elected parliament of selected Tibetan exiles. His original goal was full independence for Tibet, but by the late 1980s, he was seeking high-level autonomy instead. He is still seeking greater autonomy from China, although Dolma Gyari, deputy speaker of the parliament-in-exile has stated "If the middle path fails in the short term, we will be forced to opt for complete independence or selfdetermination as per the UN charter".

Serenity (movie)
|
Serenity is a 2005 science fiction space western movie. It was written and directed by Joss Whedon. The movie takes place in the fictional universe of the cancelled FOX science fiction television series "Firefly". It takes place about two months after the final episode, "Objects in Space". That is 500 years in the future.
"Serenity" is the story of the captain and crew of a transport and cargo spacecraft. The captain and first mate fought together on the losing side of the Unification War. Their lives of small crime are interrupted by a passenger with mental abilities who has a dangerous secret.
The movie was released in North America on September 30, 2005 by Universal Pictures. It received good reviews. It made $10.1 million during its first weekend. The movie made $25.5 million in the United States and $13.3 million in other countries.
Fans call the movie the "Big Damn Movie" ("BDM"). This is a reference to a line from the "Firefly" episode "Safe" in which Mal and Zoe call themselves "big damn heroes" after rescuing River and Simon.
Production.
The movie is based on "Firefly", a television series that was cancelled by Fox in December 2002. Fox stopped the show after 11 of its 14 episodes had been shown. After trying to get another network to show the series, creator Joss Whedon tried to sell it as a movie. He was introduced to Mary Parent with Universal Pictures, who agreed to make the movie after watching the episodes on DVD.
After Universal Studios got the movie rights to "Firefly" from Fox, Whedon began writing the screenplay. Universal wanted to start making the movie in October 2003 but problems with the script made them have to wait until June 2004 to start of shooting the movie. Universal did not want to spend the normal amount of money for a story set in space ($100 million). Whedon told them he could do it for less. He also told them he could do it in 50 days, instead of the usual 80 days. On March 3, 2004, the movie was greenlighted to start being made. It was shown to have budget of only $40 million.
They started filming the movie on June 3, 2004. Joss Whedon said that the movie would be called "Serenity" to keep it separate from the TV series. All nine of the main actors from the television series (Adam Baldwin, Alan Tudyk, Gina Torres, Jewel Staite, Morena Baccarin, Nathan Fillion, Ron Glass, Sean Maher, and Summer Glau) returned for the movie. On September 17, 2004, Joss Whedon said on the movie's official site that shooting was done.
Whedon had to take a television series that not many people had seen and explain the idea of the movie. He had to do this without boring the audience or the fans of the television series. He did this by doing things in the beginning of the movie. At first, it is a just a voice telling what has happened. It then is shown to be a school room where the voice was that of the teacher. They next showed that this was all just memories in one of the character's mind.
Since the budget was not very large, physical special effects were used as much as possible. They made as sets and props as they could to use less CGI effects. The most technically challenging scene was the mule skiff chase. Because it would cost too much, a gimbal (a hydraulic turntable) and CGI, like the pod race scene in "" could not be used. The production team to find other ways to do things. They built a trailer connected to the "hover craft" in the movie and shot the scene while riding up a highway north of Santa Clarita. "Serenity" visual effects supervisor Loni Peristere said in a Los Angeles Times article: "Traditionally this would have been, like, a 30-day shoot. I think we did it in five."
One item from the television show that could not be used again was the original set of the inside of the ship "Serenity". It had to be built for the movie, using images from the "Firefly" DVD set. The company that did the graphics for the series also had to change the computer model of "Serenity". The television model was not good enough for high-definition cinema screens and HD DVD.
Synopsis.
Five hundred years into the future, mankind has left Earth. All the people moved to a new large star system. The system is controlled by the Alliance. Away from the "core planets" people like the crew of the cargo ship "Serenity" can make a living if they stay away from Alliance ships and the Reavers - space-faring cannibals who raid the planets of "the Rim." One of the Alliance's projects is the creation of a group of warriors with mental powers. The star of this project is teenager River Tam. After her older brother Simon rescues her, the Alliance Parliament sends "The Operative", a man with no name, rank or official existence after them.
About eight months after River and Simon have joined "Serenity's" crew, the ship's captain Malcolm "Mal" Reynolds takes River with him to rob a bank. While they are robbing the bank, Reavers attack. After they escape back to "Serenity", Simon argues with Mal. Mal decides to leave Simon and River at their next stop. While at their next stop, River starts a fight that is started by a subliminal message broadcast by the Alliance in a commercial. Mal lets Simon and River keep traveling on "Serenity" while the crew talks to a techno-geek known as Mr. Universe. Mr. Universe lives on a planet inside a giant cloud of objects in space that does not let people see there is a planet there. Mr. Universe watches a video of the fight and finds the subliminal message. He also sees that River said the name "Miranda." Mal gets a call from Inara, a former passenger. He knows it is a trap, but also knows that she must be in danger. Mal goes to her. He is confronted by the Operative. The Operative tells Mal that he will let him go if Mal turns River over to him. Mal refuses and they escape from the Operative and go back to "Serenity". The crew finds out that "Miranda" is an unknown planet near the edge of the solar system. To get to Miranda, they would have to cross into Reaver territory. They think this is too dangerous. "Serenity" instead goes to Haven which is home to another former passenger, Shepherd Book. When they get to Haven, the crew sees that it has been attacked by the Alliance. They also see that Shepherd Book was hurt very bad and dying. The Operative sends a message saying he did it. He said he will keep doing things like it until River is given to him.
Mal orders that "Serenity" be made to look like a Reaver ship. They get the disguised ship through a fleet of Reaver warships. When they get to Miranda, the crew finds everyone that lived there is dead. There are dead bodies everywhere but they can not tell how the people died. The crew finds a video made after the disaster by an Alliance ship. It tells them that the Alliance made a chemical that was susposed to stop aggression and make the planet free of violence. The chemical worked so well that the people stopped doing everything, including eating, and let themselves die. In a tenth of a percent of the people, the chemical had the opposite effect. It turned them very aggressive and caused mental problems: they became the Reavers. Mal wanted to show this secret to all the worlds by using Mr. Universe's equipment. The Operative figures out where they are going and waits just outside of Reaver space with an Alliance fleet. Knowing that the Operative is likely to be waiting for them, "Serenity" opens fire on one of the Reaver ships while coming back. The other Reaver ships chase after them. "Serenity" leaves Reaver space and pass through the cloud around Mr. Universe's planet while being chased by the entire Reaver fleet. There is a large fight between the Alliance and the Reavers. The fight lets "Serenity's" pilot Wash to fly down to the planet. The Operative's ship is destroyed, and he also goes to the planet in an escape pod.
"Serenity" crashes on the planet. While the ship is damaged very badly, the crew has survived. Just as everyone begins to relax, a Reaver harpoon hits Wash, and kills him. The crew leaves "Serenity" and finds a place to fight off the Reavers while Mal goes to get to Mr. Universe and send the message. Mal finds Mr. Universe has been killed and his equipment is destroyed. He finds a message that tells him about a hidden backup transmitter. The Reavers attack the crew, and make them move back. The crew tries to close a blast door, but it will not shut all the way. River dives through the hole in the door and closes it from the other side. This traps her with the Reavers. Mal gets to the other transmitter. The Operative gets there also and they fight. Mal wins but does not kill the Operative. He leaves him to watch the video from Miranda as it is being broadcast. Mal goes back to his crew. As he is told what River did, the blast door opens to reveal River standing unhurt on an large pile of dead Reavers. A group of Alliance soldiers show up but the Operative orders them not to fight because of what he has seen on the video. The crew buried their dead and fixed "Serenity". "Serenity" leaves the planet with Mal in Wash's seat as the pilot, and River as his copilot.
Themes.
While the movie shows the Alliance as an all-powerful regime, Whedon is careful to point out that it is not that simple. "The Alliance isn't some evil empire", he says, but a largely benevolent bureaucratic force. The Alliance’s main problem is that it cannot and should not try to control all the different cultures that are a part of it. The crew of Serenity, and specifically Mal, show the idea that people should have the right to chose for themselves, even if those choices are bad.
The Operative is all that the Alliance stands for. He is, as Whedon described, the "perfect product of what's wrong with the Alliance". He is someone who is a force for good, who wants to help make his (and the Alliance's) image of a "world without sin." The Operative believes so much in this idea that he do anything to make create that world . Mal is the opposite. At the movie's beginning, he is a man who has lost all faith. By the end of the movie, however, Mal finally believes in something—freedom of choice—so strongly that he is willing to die to preserve it. Whedon has said that the most important line in the movie is Mal's to the Operative at its end: "I'm going to show you a world without sin." Whedon's point is that a world without sin is a world without choice, and that choice is what defines humanity. The Operative, who does only what he is told to do, and the inhuman Reavers, created by the Alliance's need to control people, are only two examples of this theme.

Woodworking joints
|
Joinery often refers to the part of woodworking that involves the joining together of parts of wood.
Traditional wood joinery techniques use
the distinctive material properties of wood, often without mechanical fasteners. There are different types of joinery for different structures, for example the joinery used
to build a house is different from that used to make puzzle toys,
although elements overlap.
Wood is strong when stressed along the grain (longitudinally), but weak across it (radially and tangentially). It expands and contracts in response to humidity.
This change is very small longitudinally. It is considerable, but unequal,
in the radial and tangential directions.
Styles of joinery.
Two of the most common traditions of joinery are Japanese and European. The Japanese in particular developed hundreds of types of joints and their furniture was often held together without glue or nails.

George Grenville
|
George Grenville (14 October 1712–13 November 1770) was Prime Minister of Great Britain. He was a member of the Whig Party. He was one of the few prime ministers who never was given a title of nobility.
Grenville was the second son of Richard Grenville and Hester Temple. His older brother was Richard Grenville-Temple. Grenville went to school at Eton College and at Christ Church College, Oxford. He entered Parliament in 1741 as member for Buckingham, and represented Buckingham until his death.
As Treasurer of the Navy in 1758 he introduced and carried a bill which established a fairer system of paying the wages of sailors. He stayed in office in 1761, when Pitt resigned, and in the administration of Lord Bute acted as Leader of the House of Commons. In May 1762 he became Secretary of State for the Northern Department, and in October First Lord of the Admiralty; and in April 1763 he became First Lord of the Treasury and Chancellor of the Exchequer.
While Prime Minister, his government oversaw the prosecution of John Wilkes and the passing of the American Stamp Act 1765, which led to the first disagreements between American colonies and Great Britain that led to the American Revolutionary War.
After many years of being Prime Minister, he began to have disagreements with young king George III. The king started to think that the Prime Minister was using him as a puppet. The king convinced Rockingham to become the new Prime Minister and Grenville never held an office again.
Grenville was called the "gentile shepherd" because he bored the House by asking over and over again, during the debate on the Cider Bill of 1763, that somebody should tell him "where" to lay the new tax if it was not to be put on cider. Pitt whistled the air of the popular tune "Gentle Shepherd, tell me where", and the House laughed. Though few excelled him in a knowledge of the forms of the House or in mastery of administrative details, he lacked tact in dealing with people and with affairs.
In 1749 Grenville married Elizabeth Wyndham (before 1731-5 December 1769), daughter of Sir William Wyndham. They had seven children.

Harald Hardrada
|
Harald Sigurdsson (; – 25 September 1066) was also known as Harald of Norway and as Hardrada (, Modern Norwegian: , "stern counsel" or "hard ruler") in the sagas.
Harald was King of Norway (as Harald III) from 1046 to 1066. Also, he unsuccessfully claimed the Danish throne until 1064 and the English throne in 1066. Before becoming king, Harald had spent about fifteen years in exile as a mercenary and military commander in Kievan Rus' and in the Varangian Guard in the Byzantine Empire.
When he was fifteen years old, in 1030, Harald fought with his half-brother Olaf against Cnut (Canute). Olaf sought to reclaim the Norwegian throne, which he had lost two years earlier to Danish King Canute. In the battle, Olaf and Harald were defeated by forces loyal to Canute. Harald was forced into exile to Kievan Rus'. After some time in the army of Grand Prince Yaroslav the Wise, Harald moved on to Constantinople with his companions around 1034.There, he commanded the Byzantine Varangian Guard.
Harald became wealthy during his time in the Byzantine Empire. He shipped the money to Yaroslav in Kievan Rus' for safekeeping. He finally left the Byzantines in 1042 and returned to Kievan Rus' to prepare his campaign to reclaim the Norwegian throne. In his absence, Olaf's illegitimate son Magnus the Good had taken the throne and become king of Denmark.
In 1046, Harald joined forces with Magnus's rival in Denmark, the pretender Sweyn II of Denmark, and started raiding the Danish coast. Magnus, unwilling to fight his uncle, agreed to share the kingship with Harald, who would in turn share his wealth. The co-rule ended abruptly the next year, when Magnus died, and so Harald became the sole ruler of Norway.
Domestically, Harald crushed all opposition and outlined the union of Norway under a national rule. Harald's reign was probably one of relative peace and stability, and he set up a viable coin economy and foreign trade. Probably seeking to restore Canute's North Sea Empire, Harald also claimed the Danish throne and spent nearly every year until 1064 by raiding the Danish coast and fighting his former ally, Sweyn. Although the campaigns were successful, he was never able to conquer Denmark.
Not long after Harald had renounced his claim to Denmark, the former Earl of Northumbria, Tostig Godwinson, the brother of the English king, Harold Godwinson, pledged his allegiance to Harald and invited him to claim the English throne. Harald invaded northern England with 10,000 troops and 300 longships in September 1066 and raided the coast and defeated English regional forces of Northumbria and Mercia in the Battle of Fulford, near York.
Although initially successful, Harald was defeated and killed in an attack by Harold's forces at the Battle of Stamford Bridge, which wiped out almost all of entire army.
Modern historians have often considered Harald's death, which brought an end to his invasion, as the end of the Viking Age. The famous "Anglo-Saxon Chronicle" records those events.

Normans
|
The Normans were Vikings who settled in northern France. There they made a kingdom called "Normandy".
In 1066 the Normans attacked England and took over. The battle was called The Battle Of Hastings. They ruled England for about 300 years. There they built the Tower of London, Windsor Castle and many other stone castles.
Norman life.
Clothes.
Normans wore woollen tunics and sometimes they wore a waistband to keep the tunic in place. The men also wore long cloaks.
Food.
Normans ate dairy, oatmeal porridge, green vegetables and sometimes meat. They often used honey as a sweetener and for mead (an alcoholic drink).
Castles.
Normans built many stone castles that often had moats around them to protect them from intruders.
Houses.
Norman houses had a wooden frame with sticks and twigs woven in between, which is called wattle, and then it was all covered in a layer of daub which was made from mud, wet clay, dung and straw. The roofs were usually thatched.
Normans in Ireland.
Diarmuid MacMurrough, King of Leinster kidnapped the King of Breifne’s wife. Then Rory O’Connor, the High King of Ireland fired him from being the King of Leinster. Diarmuid still wanted to be king so he hired some Normans, lead by Strongbow to help him get the throne back. Diarmuid had to pay Strongbow so he said that he could marry his daughter and become king when Diarmuid died. Strongbow agreed to this. They first came to Ireland at Bannow Bay, Wexford in 1169 and soon they got the throne back for Diarmuid. King Henry II, King of England and part of France, thought that Strongbow was getting too powerful since Strongbow wasn’t actually the king, so Henry decided to take over the whole of Ireland. He sent over some other Normans who arrived at Ireland in Baginbun, Wexford in 1170. Then King Henry II became King of Ireland as well.
While the Normans were in Ireland they built the original Dublin castle and many other stone castles.
Normans probably introduced rabbits and fallow deer to Ireland for meat and skins.

Captain
|
Captain is a military rank.
Captains are officers in an army. In a navy, the commander of an entire ship is called "Captain" even if he is actually a lower rank. A Navy Captain rank is equal to the army rank of colonel. Another type of captain may command a merchant vessel or other ship that is not in a navy.
There are also captains in other uniformed organisations, including the police. A leader of a sports team is also called a captain, as well as the pilot of an airliner.

Wire rope
|
Wire rope consists of several strands laid (or 'twisted') together like a helix. Each strand is likewise made of metal wires laid together like a helix. Initially wrought iron wires were used, but today steel is the main material used for wire ropes.
History & materials.
Modern wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany. It was quickly accepted because it was better than ropes made of hemp or to metal chains, such as had been used before.
Wilhelm Albert's first ropes consisted of wires twisted about a hemp rope core, six such strands then being twisted around another hemp rope core in alternating directions for extra stability. Earlier forms of wire rope had been made by covering a bundle of wires with hemp.
In America wire rope was later manufactured by John A. Roebling, forming the basis for his success in suspension bridge building. Roebling introduced a number of innovations in the design, materials and manufacture of wire rope.
Manufacturing a wire rope is similar to making one from natural fibres. The individual wires are first twisted into a strand, then six or so such strands again twisted around a core. This core may consist of steel, but also of natural fibres such as sisal, manila, henequen, jute, or hemp. This is used to cushion off stress forces when bending the rope.
Construction & specification.
The specification of a wire rope type, including the number of wires per strand, the number of strands, and the lay of the rope, are is documented using a commonly accepted coding system, with abbreviations. For example, the rope shown in the figure "Wire rope construction" is designated:
6x19 FC RH OL FSWR
Each of the sections of the wire rope designation described above is variable. There are therefore a large number of combinations of wire rope that can be specified in this manner. The following abbreviations are commonly used to specify a wire rope.

Liekkiö
|
Finnish mythology has several different kinds of Liekkiö ("flamey"). One of them is Ihtiriekko, a ghost of a bastard child.
Stories tell that a woman had sex with someone else than her husband. Maybe she did not even have a husband. She then get pregnant and gave birth to a baby. This way to make a baby was not accepted by church and society - that kind of baby is called bastard. Mother had to kill her bastard child to avoid being blamed by priests or other people. Mother then buried child outside graveyard and without priests blessing the body. The soul of the baby could not go to heaven because their body was not at a graveyard and was not blessed by a priest. This is why they became a ghost.
This ghost could make terrible noise until somebody dugs up their body and buries it in graveyard. Such ghost people are called Ihtiriekko. Ghosts could also be quiet, but they might be seen as a flame in forest, like will o' the wisp. Such ghost people are called Liekkiö.

Bastard
|
A bastard is a person who was born of parents who are not married to each other. It is considered by some cultures and individuals as a nasty or insulting word or sometimes even profanity, with the term illegitimate being a little more polite. Some cultures see illegitimate children as dirty or bad and accept sexual relations only between married couples.

Gödel number
|
In formal number theory a Gödel numbering is a function which assigns to each symbol and formula of some formal language a unique natural number called a Gödel number (GN). The concept was first used by Kurt Gödel for the proof of his incompleteness theorem.
A Gödel numbering can be interpreted as an encoding where a number is assigned to each symbol of a mathematical notation, and a stream of natural numbers can then represent some form or function. A numbering of the set of computable functions can then be represented by a stream of Gödel numbers (also called effective numbers). Rogers' equivalence theorem states criteria for which those numberings of the set of computable functions are Gödel numberings.
Definition.
Given a countable set "S", a Gödel numbering is an injective function
with both "f" and formula_2 (the inverse of "f") being computable functions.
Examples.
Base notation and strings.
One of the simplest Gödel numbering schemes is used every day: The correspondence between integers and their representations as strings of symbols. For example, the sequence 2 3 is understood, by a particular set of rules, to correspond to the number twenty-three. Similarly, strings of symbols from some alphabet of "N" symbols can be encoded by identifying each symbol with a number from 0 to "N" and reading the string as the base "N"+1 representation of an integer.

Formal language
|
In mathematics, computer science and linguistics, a formal language is one that has a particular set of symbols, and whose expressions are made according to a particular set of rules. The symbol formula_1 is often used as a variable for formal languages in logic.
Unlike natural languages, the symbols and formulas in formal languages are syntactically and semantically related to one another in a precise way. As a result, formal languages are completely (or almost completely) void of ambiguity.
Examples.
Some examples of formal languages include:
Specification.
A formal language can be specified in a great variety of ways, such as:

Alphabet (computer science)
|
In computer science, an alphabet is a finite non-empty set. The elements of an alphabet are called the letters or symbols of the alphabet.
An example of an alphabet is formula_1 which may be used for Morse code or "{begin, if, else, for, while}" which may be the keywords of a Programming language.
The set of natural numbers is not an alphabet because as it is not finite.
The alphabet which is used the most in computer science is "{0,1}". It is called the binary alphabet because it contains two symbols. An alphabet can be used to make a string (or word). This is a finite Sequence of letters from the alphabet. For example, a string of length 5 over "{0,1}" is "01101".
The empty string is the string containing no letters (it is often written as formula_2). The empty string is a string over any alphabet.
If we have an alphabet called formula_3, then we write the set of "all" strings that can be made from formula_3 as formula_5. This is called the Kleene star (or Kleene closure) of formula_3. It is named after the mathematician Stephen Cole Kleene.
The Kleene star of the binary alphabet is formula_7. The three dots after 001, show that we cannot write the Kleene star of an alphabet in full because it is an infinite set.
Alphabets are important because they are used in studying formal languages, finite automata and very difficult questions in computer science about what can be computed and what can not.

Empty string
|
The empty string is the unique string of no characters over some alphabet Σ. It is written as "ε" or "λ". The length of this empty string is 0.
In simple words, given some characters of an alphabet, the empty string is the "word" that can be made if no letters are used. There is of course only one such word.
Under concatenation, the empty string is the identity element of the free monoid on Σ. That is, for any string "s", "s"ε = ε"s" = s.
Representations.
In many programming languages, the empty string is written with two double quotes: "". The empty string is also sometimes noted by the Greek letter λ.
Implementation.
In C, the empty string is represented by a character array with a null character in the zeroeth position. Note that all strings in C are terminated by a null character.
