John Dalton born in September 6, 1766 and died on July 27 1844, was an English chemist and physicist, born at Eaglesfield, near Cockermouth in Cumbria. He is best known for his advocacy of the atomic theory and his research into colour blindness (sometimes referred to as Daltonism, in his honour).
Dalton was the first to provide a scientific description of color blindness (1794), a condition from which he suffered and which was long called "Daltonism." Dalton recorded over 200,000 observations of the atmosphere in his notebooks, and studied mixed gases and the expansion of gases under heat.
Joseph John Thomson was born on December 18, 1856 near Manchester, England. His father died when "J.J." was only sixteen. Thomson attended Owens College in Manchester, where his professor of mathematics encouraged him to apply for a scholarship at Trinity College, one of the most prestigious of the colleges at Cambridge University.
homson's achievements were honored in numerous ways, and mark him as among the most accomplished physicists of his era. In 1906 he was awarded the Nobel prize in physics for his researches into the discharge of electricity in gases.he died on August 30, 1940. one hundred years ago, amidst glowing glass tubes and the hum of electricity, the British physicist J.J. Thomson was venturing into the interior of the atom. At the Cavendish Laboratory at Cambridge University, Thomson was experimenting with currents of electricity inside empty glass tubes.
Experiments by J.J. Thomson in 1897 led to the discovery of a fundamental building block of matter.
In 1898 Rutherford was appointed to the chair of physics at McGill University in Montreal, Canada, where he did the work which gained him the 1908 Nobel Prize in Chemistry. Rutherford had demonstrated that radioactivity was the impulsive disintegration of atoms. rutherford noticed that a sample of radioactive material invariably took the same am In 1917 he returned to the Cavendish as Director. Under him, Nobel Prizes were awarded to Chadwick for discovering the neutron of time for half the sample to decay.
