J.J. Thomson attended Trinity College at Cambridge, where he would come to head the Cavendish Laboratory. His research in cathode rays led to the discovery of the electron, and he pursued further innovations in atomic structure exploration. Thomson won the 1906 Nobel Prize in Physics, among many accolades.
Joseph John Thomson, who was always called J.J., was born in Cheetham Hill, England, near Manchester, in 1856. His father was a bookseller who planned for Thomson to be an engineer. When an apprenticeship at an engineering firm couldn't be found, Thomson was sent to bide his time at Owens College at the age of 14. In 1876, he received a small schol...
In 1894, Thomson began studying cathode rays, which are glowing beams of light that follow an electrical discharge in a high-vacuum tube. It was a popular research topic among physicists at the time because the nature of cathode rays was unclear. Thomson devised better equipment and methods than had been used before. When he passed the rays through...
Thomson married Rose Paget, one of his students, in 1890. They had one daughter, Joan, and one son, George Paget Thomson, who went on to become a physicist and win a Nobel Prize of his own. J.J. Thomson published 13 books and more than 200 papers in his lifetime. In addition to being awarded the Nobel Prize in 1906, he was knighted in 1908 by King ...
On April 30, 1897, Thomson made his discovery public while giving a lecture to the Royal Institution. The evidence he produced in support of his theoretical claims was culled from a series of innovative experiments with cathode ray tubes.
Thomson's claim to be the discoverer of the electron rests on two key observations. First, he found that the value of e/m was of the order of 1000 times larger than its value for the lightest particle then known, which was the hydrogen ion in electrolysis.
Overview. Late in the nineteenth century physicists were working hard to understand the properties of electricity and the nature of matter. Both subjects were transformed by the experiments of J. J. Thomson, who in 1897 showed the existence of the charged particles that came to be known as electrons.
Thomson's discovery of the electron began in 1895 with a series of experiments in the Cavendish Laboratory. Influenced by the work of James Clerk Maxwell land the discovery of the X-ray, Thomson deduced that cathode rays (produced by Crookes tube) exhibited a single charge-to-mass ratio e m and must be composed of a single type of negatively ...
Apr 25, 2024 · J.J. Thomson discovered the electron in 1897 and led the Cavendish Laboratory into a world-class research institution. His work opened the field of subatomic physics to experimental investigation and helped unravel the inner workings of the atom.
