Ernest Rutherford

Ernest Rutherford was born in New Zealand in 1871 as lead of 12 children. It was Rutherford who first split an mite and who discovered the ingredientic nucleus, a name that he invented. For this he is regarded as the greatest tryal physicist of his time. Rutherford was virtuoso of the first and most spellant researchers in nuclear physics. Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of beam. By covering his Uranium with thin foils of aluminum, gradually increasing the crook of foils. For the first three layers of foil the beam of light escaping from the uranium change magnitude progressively, suggesting an ordinary law of absorption. More thickness of aluminum, however, had little brook effect in reducing the radiation at first, precisely eventually the intensity of the radiation began to diminish again as even more foils were added. These experiments showed that t here were at least ii distinct types of radiation- oneness that is very readily absorbed, which he called the of significance - radiation, and the other more penetrative character which he called the of import - radiation. He also had believed that he had found a tercet more penetrating radiation. The Frenchman, Paul Villard, officially gave this third radiation.

He named it, after Rutherfords first two radiation discoveries, the gamma- radiation. It was these discoveries in radiation that opened the door to the rest of Rutherford discoveries. Using this alpha radiation, Rutherford started to experiment putting it through other materials to get the effec! ts. It was in one of these experiments with gilt that he was able to figure out what an atom looks like. He found that a countable number of alpha particles actually bounced back from a thin sheet of deluxe foil. Of course the majority of the particles went straight through the gold and were scarcely slightly scattered. Rutherford said that this was the most surprising result he had known....If you want to get a full essay, order it on our website: BestEssayCheap.com
