Bøger af Joseph John Thomson

Manchester-born Sir Joseph John Thomson (1858-1940), discoverer of the electron, was one of the most important Cambridge physicists of the later nineteenth and first half of the twentieth centuries. Succeeding Lord Rayleigh as Cavendish Professor of Experimental Physics, he directed the research interests of the laboratory, and eight of his students, including Rutherford, went on to win Nobel Prizes, as Thomson himself did in 1906. He was knighted in 1908, received the Order of Merit in 1912, and became Master of Trinity College in 1918. He also served as President of the Royal Society from 1915 from 1920 and was a government advisor on scientific research during World War I. This autobiography, published in 1936, covers all aspects of his career - his student days in Manchester, arrival in Cambridge, and growing international reputation. It gives a fascinating picture of Cambridge life and science at a dynamic period of development.

This 1893 publication is a central text in the work of the Nobel prize winning physicist Sir Joseph John Thomson (1858-1940). Intended as an extension of James Clerk Maxwell's Treatise on Electricity and Magnetism, it documents the important shift in Thomson's thinking towards the model of the atomic electric field, a theory that would eventually lead to his discovery of the electron. In Chapter 1, Thomson documents his experiments with Faraday tubes, using them to physically demonstrate a 'molecular theory of electricity'. Chapter 2 considers the discharge of electricity through gases, Chapter 3 theories of electrostatics, and Chapters 4-6 are primarily concerned with alternating currents. In addition to providing crucial insight into Thomson's evolving theory of the atom, Recent Researches underscores his commitment to experimental physics, which offers 'all the advantages in vividness which arise from concrete qualities rather than abstract symbols'.
