United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emperor Of The French
Emperor of the French ( French: ''Empereur des Français'') was the title of the monarch and supreme ruler of the First and the Second French Empires. Details A title and office used by the House of Bonaparte starting when Napoleon was proclaimed Emperor on 18 May 1804 by the Senate and was crowned Emperor of the French on 2 December 1804 at the cathedral of Notre-Dame de Paris, in Paris, with the Crown of Napoleon. The title emphasized that the emperor ruled over "the French people" (the nation) and not over France (the state). The old formula of "King of France" indicated that the king owned France as a personal possession. The new term indicated a constitutional monarchy. The title was purposely created to preserve the appearance of the French Republic and to show that after the French Revolution, the feudal system was abandoned and a nation-state was created, with equal citizens as the subjects of their emperor. (After 1 January 1809, the state was officially referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humphry Davy
Sir Humphry Davy, 1st Baronet, (17 December 177829 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited to have been the first to discover clathrate hydrates in his lab. In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery.
