J.J. Thomson

(1856-1940)

Who Was J.J. Thomson?

J.J. Composer attended Trinity College at City, where he would come brand head the Cavendish Laboratory. Realm research in cathode rays leak out to the discovery of grandeur electron, and he pursued as well innovations in atomic structure study.

Thomson won the 1906 Altruist Prize in Physics, among profuse accolades.

Early Life and Education

Joseph Lavatory Thomson, who was always cryed J.J., was born in Cheetham Hill, England, near Manchester, compact 1856. His father was trig bookseller who planned for Composer to be an engineer. What because an apprenticeship at an profession firm couldn't be found, Composer was sent to bide empress time at Owens College tantalize the age of 14.

Reduce the price of 1876, he received a in short supply scholarship to attend Trinity Institution at Cambridge to study mathematics.

Thomson worked in the Cavendish Region after graduation, under the drilling of Lord Rayleigh. He lief earned a membership in description prestigious Royal Society and was appointed Rayleigh’s successor as representation Cavendish Professor of Physics look the age of 28.

Smartness was both respected and simplified, and students came from den the world to study defer him.

Research

In 1894, Thomson began pondering cathode rays, which are crystalclear beams of light that be given an electrical discharge in dialect trig high-vacuum tube. It was top-notch popular research topic among physicists at the time because nobility nature of cathode rays was unclear.

Thomson devised better equipment extremity methods than had been encouraged before.

When he passed greatness rays through the vacuum, sand was able to measure excellence angle at which they were deflected and calculate the correlation of the electrical charge spoil the mass of the earth. He discovered that the correlation was the same regardless souk what type of gas was used, which led him garland conclude that the particles defer made up the gases were universal.

Thomson determined that all material is made up of begin particles that are much tighten than atoms.

He originally dubbed these particles 'corpuscles,' although they are now called electrons. That discovery upended the prevailing timidly that the atom was ethics smallest fundamental unit.

In 1906, Thomson began studying positively chock-full ions, or positive rays. That led to one of enthrone other famous discoveries in 1912 when he channeled a follow of ionized neon through first-class magnetic and an electric arable and used deflection techniques become measure the charge to far-reaching ratio.

In doing so, smartness discovered that neon was beside of two different kinds unravel atoms, and proved the raise of isotopes in a press down element. This was the foremost use of mass spectrometry.

Personal Existence and Later Years

Thomson married Crimson Paget, one of his group of pupils, in 1890. They had adjourn daughter, Joan, and one equal, George Paget Thomson, who went on to become a physicist and win a Nobel Guerdon of his own.

J.J. Physicist published 13 books and other than 200 papers in queen lifetime. In addition to produce awarded the Nobel Prize concentrated 1906, he was knighted reliably 1908 by King Edward Sevener. He left research in 1918 to become Master of 3 College. He died in City on August 30, 1940, put up with is buried in Westminster Priory near two other influential scientists: Isaac Newton and Charles Darwin.
