The Biography of
J.J Thomson
J.J Thomson was born in December 18, 1856 in Cheetham Hill, England near Manchester his father was bookseller and planned his son J.J Thomson to be an engineer. But when apprenticeship at an engineering firm couldn’t be found, J.J. Thomson went to spend his time at Owens College at the age of 14. When J.J. Thomson graduated at Owens College in the year of 1876, he had received a small scholarship to attend Trinity College at Cambridge to study mathematics. After his graduation at Trinity College, J.J. Thomson worked in the Cavendish Laboratory under the instructions of Lord Rayleigh. At the age of twenty-eight J.J. Thomson quickly earned a membership in the prestigious Royal Society and was appointed Rayleigh’s successor at the Cavendish Professor of Physics and J.J. Thomson was both respected and admired, and students came from around the world to study with him.
J.J. Thomson accomplished many things in his life when he was working at Cavendish Laboratory. He began researching cathode rays, which are glowing beams of light that follow an electrical discharge in a high-vacuum tube. When he was testing his experiment he had discover that the ratio was the same regardless of what type of gas was used in this experiment and led him to conclude that the particles that made up the gases were universal. Then J.J. Thomson determined that all matter is made up of tiny particles that are smaller than atoms. J.J. Thomson began researching positively charged ions, or in other words positive rays in the year 1906. In the year 1912 J.J. Thomson soon discovered that neon was composed of two different kinds of atoms, and proved the existence of isotopes in a stable element.
I think J.J. Thomson was in our textbook because when he was researching particles in his laboratory. I also think he is in are textbook because J.J. Thomson determined that all matter is made up of little particles and that they...
