Extractions: Sir Joseph John Thomson, b. Dec. 18, 1856, d. Aug. 30, 1940, is universally recognized as the British scientist who discovered and identified the electron. At the age of 27 he succeeded (1884) Lord Rayleigh as professor of physics at Trinity College, Cambridge, and was named director of its Cavendish Laboratory in the same year, continuing in that position until 1919. Thomson demonstrated (1897) that cathode rays were actually units of electrical current made up of negatively charged particles of subatomic size. He believed them to be an integral part of all matter and theorized a model of atomic structure in which a quantity of negatively charged electrons was embedded in a sphere of positive electricity, the two charges neutralizing each other. For these investigations he won (1906) the Nobel Prize for physics; in 1908 he was knighted. Subsequently, Thomson turned his attention to positively charged ions. His research showed that neon gas was made up of a combination of two different types of ions, each with a different charge, or mass, or both. He did this by using magnetic and electric fields to deflect the stream of positive ions of neon gas onto two different parts of a photographic plate. This demonstration clearly pointed to the possibility that ordinary elements might exist as isotopes (varieties of atoms of the same element, which have the same atomic number but differ in mass).

Extractions: From PSCF (June 1986): 131-132. I t so happened that my first graduate course was given by one of the early (after 1895) research students at the Cavendish Laboratory. I asked the professor to give a talk to young people on "My Religion as a Physicist." He replied, "Although I attend church regularly, I just don't talk about it." He was following in the footsteps of his mentor, J. J. Thomson. Joseph John Thomson was born December 18th, 1856, in Cheetham Hill, a Manchester suburb. His father, Joseph James, a bookseller and publisher, died when he was sixteen. His mother, Emma Swindells, lived until 1901. He and his brother, Frederick Vernon (younger by two years), used to spend their summer holidays with her. At thirty-four, he himself married, in the church of St. Mary the Less, a sometime physics student, Rose Elizabeth Paget, daughter of the Regius Professor of Physics at the University of Cambridge. They had two children, George Paget and Joan Paget. Their home became a social center-at first breakfast parties, later teas, finally dinners-all more a duty than a pleasure. At fourteen, intending to become an engineer, he entered Owens College (Manchester University, 1880). There he studied with Osborne Reynolds and Balfour Stewart, who sparked his interest in physics. (He received awards in mathematics and engineering at the ages of sixteen and eighteen; he had no chemistry.) At twenty he entered Trinity
Extractions: The Thomson Building, 1927 Nor is Science taught in the schools in a perfunctory manner. On that point also the Master was most emphatic. He observed that next month about a thousand boys will be competing at Cambridge – and a similar number at Oxford – for scholarships at the various colleges, all of whom will show "quite creditable acquaintance with their subjects, or they would not enter the lists, while from 100 to 150 at each University will attain a standard which may not be paralleled in any other country." Top Right^^ There was a time when industrialists replied to the criticisms of those who urged them to a more generous recognition of Science by saying that there was no available supply of men with the requisite training. That is not true to-day. The supply is over-abundant compared with the demand. Yet, as the Master of Trinity observes, "We cannot run the industries of to-day on the Science of yesterday. If industry is to flourish, there must be close consultation between Science and industry." Some of the most prosperous industries of to-day have been founded on that close consultation. Without the scientist the dye industry would have remained in the primitive state of a century ago, and the electrical and art-silk industries would never have been born. If there is a British industry which at the moment conspicuously demands that "close consultation" as the first essential of its recovery from the slough of depression into which it has sunk, it is the coal industry–given, of course, the bold internal reorganisation which is no less palpably required.
