Benjamin Franklin (1706-1790) His kite experiment demonstrated that lightning is electricity. He was the first to use the terms positive and negative charge. Franklin was one of seventeen children. He quit school at age ten to become aprinter. His life is the classic story of a self-made man achieving wealth and fame through determination and intelligence. James Watt (1736-1819) was born in Scotland. Although he conducted no electrical experiments, he must not be overlooked. He was an instrument maker by trade and set up a repair shop in Glasgow in 1757. Watt thought that the steam engine would replace animal power, where the number of horses replaced seemed an obvious way to measure the charge for performance. Interestingly, Watt measured the rate of work exerted by a horse drawing rubbish up an old mine shaft and found it amounted to about 22,000 ft-lbs per minute. He added a margin of 50% arriving at 33,000 ft-lbs. William Thomson, Lord Kelvin (1824-1907) was best known in his invention of a new temperature scale based on the concept of an absolute zero of temperature at -273°C (-460°F). To the end of his life, Thomson maintained fierce opposition to the idea that energy emitted by radioactivity came from within the atom. One of the greatest scientific discoveries of the 19th century, Thomson died opposing one of the most vital innovations in the history of Thomas Seebeck (1770-1831) a German physicist was the discoverer of the He twisted two wires made of different metals and heated a junction where the two wires met. He produced a small current. The current is the result of a flow of heat from the hot to the cold junction. This is called thermoelectricity. Thermo is a Greek word meaning heat. Michael Faraday (1791-1867) an Englishman, made one of the most significant discoveries in the history of electricity: Electromagnetic induction. His pioneering work dealt with how electric currents work. Many inventions would come from his experiments, but they would come fifty to one hundred Failures never discouraged Faraday. He would say; "the failures are just as important as the successes." He felt failures also teach. The farad, the unit of capacitance is named in the honor of Michael Faraday. James Maxwell (1831-1879) a Scottish mathematician translated Faraday's theories into mathematical expressions. Maxwell was one of the finest mathematicians in history. A maxwell is the electromagnetic unit of magnetic flux, named in his honor. Today he is widely regarded as secondary only to Isaac Newton and Albert Einstein in the world of science. Thomas Alva Edison (1847-1931) was one of the most well known inventors of all time with 1093 patents. Self-educated,Edisonwas interested in chemistry and electronics.During the whole of his life, Edison received only three months of formal schooling, and was dismissed from school as being retarded, though in fact a childhood attack of scarlet fever had left him Nikola Tesla was born of Serbian parents July 10, 1856 and died a broke and lonely man in New York City January 7, 1943. He envisioned a world without poles and power lines. Referred to as the greatest inventive genius of all time. Tesla's system triumphed to make possible the first large-scale harnessing of NiagaraFalls with the first hydroelectric plant in the United States in 1886. October 1893 George Westinghouse (1846-1914)was awarded the contract to build the first generators at Niagara Falls. He used his money to buy up patents in the electric field. One of the inventions he bought was the transformer from William Stanley. Westinghouse invented the air brake system to stop trains, the first of more than one hundred patents he would receive in this area alone. He soon founded the Westinghouse Air Brake Alexander Graham Bell (1847-1922) born in Scotland, was raised in a family that was interested and involved in the science of sound. Bell's father and grandfather both taught speech to the deaf. A unit of sound level is called a bel in his honor. Sound levels are measured in tenths of abel, or decibels. The abbreviation for decibel is dB. Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube. He laid the foundation for the future development of radio, telephone, telegraph, and even television. He was one of the first people to demonstrate the existence of electric waves. Hertz was convinced that there were electromagnetic waves in space. Otto Hahn (1879-1968), a German chemist and physicist, made the vital discovery which led to the first nuclear reactor. He uncovered the process of nuclear fission by which nuclei of atoms of heavy elements can break into smaller nuclei, in the process releasing large quantities of energy. Hahn was awarded the Nobel prize for chemistry in 1944. Albert Einstein (1879-1955). Einstein's formula proved that one gram of mass can be converted into a torrential amount of energy. To do this, the activity of the atoms has to occur in the nucleus. E= energy, M = mass, and C =the speed of light which is 186,000 miles per second. When you square 186,000 you can see it would only take a small amount of mass to produce a huge amount of energy.

Planets

Nine Planets - Solar System Tour This website is an overview of the history, mythology and current scientific knowledge of the planets, moons and other objects in our solar system. Each page has our text and NASA's images, some have sounds and movies, most provide references to additional related information. Please visit our Astronomy news section which gives news, notes and general observations, we also have an interactive tour of the solar system (loads in a new window) All planets can be seen with a small telescope or binoculars and private observatories continue to provide useful information. But the possibility of getting up close with interplanetary spacecraft has revolutionized planetary science. Very little of this site would have been possible without the space program. Nevertheless, there's a lot that you can see with very modest equipment or even with just your own eyes. Past generations of people found beauty and a sense of wonder contemplating the night sky. Today's scientific knowledge further enhances and deepens that experience. And you can share in it by simply going out in the evening and looking up. Spitronics @ GAP Gravity Auto Parts specializing in Spitronics Sales & Technical gapsa.co.za The Sun The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest). It is often said that the Sun is an "ordinary" star. That's true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun. Jupiter Jupiter is the fourth brightest object in the sky (after the Sun, the Moon and Venus). It has been known since prehistoric times as a bright "wandering star". But in 1610 when Galileo first pointed a telescope at the sky he discovered Jupiter's four large moons Io, Europa, Ganymede and Callisto (now known as the Galilean moons) and recorded their motions back and forth around Jupiter. Mercury In Roman mythology Mercury is the god of commerce, travel and thievery, the Roman counterpart of the Greek god Hermes, the messenger of the Gods. The planet probably received this name because it moves so quickly across the sky. Mercury has been known since at least the time of the Sumerians (3rd millennium BC).
