In 1880, he obtained his Bachelor of Arts degree in mathematics ( Second Wrangler in the Tripos and 2nd Smith's Prize).

He moved on to Trinity College, Cambridge, in 1876. His parents planned to enroll him as an apprentice engineer to Sharp, Stewart & Co, a locomotive manufacturer, but these plans were cut short when his father died in 1873. In 1870, he was admitted to Owens College in Manchester (now University of Manchester) at the unusually young age of 14. His early education was in small private schools where he demonstrated outstanding talent and interest in science. Thomson was a reserved yet devout Anglican. He had a brother, Frederick Vernon Thomson, who was two years younger than he was. His father, Joseph James Thomson, ran an antiquarian bookshop founded by Thomson's great-grandfather. His mother, Emma Swindells, came from a local textile family. Joseph John Thomson was born on 18 December 1856 in Cheetham Hill, Manchester, Lancashire, England. 3.5.4 Measurement of mass-to-charge ratio.Thomson was also a teacher, and several of his mentees also went on to win Nobel Prizes. Thomson was awarded the 1906 Nobel Prize in Physics for his work on the conduction of electricity in gases. His experiments to determine the nature of positively charged particles, with Francis William Aston, were the first use of mass spectrometry and led to the development of the mass spectrograph. Thomson is also credited with finding the first evidence for isotopes of a stable (non-radioactive) element in 1913, as part of his exploration into the composition of canal rays (positive ions). In 1897, Thomson showed that cathode rays were composed of previously unknown negatively charged particles (now called electrons), which he calculated must have bodies much smaller than atoms and a very large charge-to-mass ratio. Sir Joseph John Thomson OM PRS (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be discovered.

Scholarly yet accessible to those with basic physics knowledge, this book should be of interest to historians of science, professional scientists and engineers, teachers and students of physics, and general readers interested in the development of modern physics.Owens College (now the University of Manchester)

The author also focuses on the controversies over N-rays, Becquerel's positive electron, and the famous Ehrenhaft-Millikan dispute over subelectrons. It explores the events leading to Millikan's unambiguous isolation of the electron and the simultaneous circumstances surrounding the birth of Ernest Rutherford's nuclear atom and the discovery of radioactivity in 1896. It also provides an overview of the history of modern physics up to the advent of the old quantum theory around 1920.Ĭonsolidating scholarly material while incorporating new material discovered by the well-respected author, the book covers the continental and English race for the source of the cathode rays, culminating in Thomson's corpuscle in 1897. The book traces the evolution of the concept of electrical charge, from the earliest glow discharge studies to the final cathode ray and oil drop experiments of J.J. Thomson's Electron presents the compelling story of the discovery of the electron and its role as the first subatomic particle in nature. Flash of the Cathode Rays: A History of J.J. The electron is fundamental to almost all aspects of modern life, controlling the behavior of atoms and how they bind together to form gases, liquids, and solids.
