The 1904 Thomson model was disproved by the 1909 gold foil experiment performed by Hans Geiger and Ernest Marsden.This gold foil experiment was interpreted by Ernest Rutherford in 1911 to suggest that there is a very small nucleus of the atom that contains a very high positive charge (in the case of gold, enough to balance the collective negative charge of about 100 electrons).New Zealand-English physicist who laid the groundwork for the development of nuclear physics. Birks, Rutherford at Manchester (1962), 108, without citation.He identified alpha, beta and gamma emissions during radioactive decay, and devised the alpha-particle scattering experiment that led to the discovery of the atomic nucleus. Webmaster has not been able to find any earlier example of the quote in print. I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art.The electrons (as we know them today) were thought to be positioned throughout the atom in rotating rings.In this model the atom was also sometimes described to have a "cloud" of positive charge.
Dr Cherry Lewis from the University of Bristol will talk about the history of dating the age of the Earth at the BA Festival of Science in York on Thursday 13 September.
His conclusions led him to propose the Rutherford model of the atom.
When asked for your age, it's likely you won't slip (with the exception of a recent birthday mistake).
The best sprinters in this road of investigation are Becquerel and the Curies... Collected in 'The British Association at Winnipeg', Nature (), 81. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.[Recalling in 1936 the discovery of the nucleus in 1909, when some alpha particles were observed instead of travelling through a very thin gold foil were seen to rebound backward, as if striking something much more massive than the particles themselves.] Should a young scientist working with me come to me after two years of such work and ask me what to do next, I would advise him to get out of science.
After two years of work, if a man does not know what to do next, he will never make a real scientist.

As Thomas Huxley, Darwin’s chief advocate said: ‘Biology takes its time from Geology’.” In 1898 Marie Curie discovered the phenomenon of radioactivity and by 1904 Ernest Rutherford, a physicist working in Britain, realised that the process of radioactive decay could be harnessed to date rocks.
