Jubilee of the Discovery of the Electron

Abstract

The Institute of Physics and the Physical Society, in collaboration with the Institution of Electrical Engineers, will celebrate, on September 25 and 26, the jubilee of the discovery of the electron by J. J. Thomson. Special lectures and meetings are also being arranged at various centres in the Dominions. In London, a lecture addressed to the non-scientific public by Sir Clifford Paterson will be given at the Central Hall, Westminster, at 7.30 p.m. on September 25 entitled “The Electron Liberated”. The lecture will be illustrated by experiments and demonstrations. Admission is by ticket only, which may be obtained free of charge from the Institute of Physics, 47 Belgrave Square, S.W.I; requests should be accompanied by an addressed envelope. Industrial organisations and universities have collaborated with the authorities at the Science Museum, South Kensington, in arranging a special exhibition, to be opened on September 26, which will remain open for about three months. The exhibition is designed to show the principles underlying the applications of the many devices in which the electron plays an essential part, and to show the important part these developments play in modern daily life. The exhibits will range from Thomson's original apparatus to the most modern developments, such as the electron microscope. A handbook has been specially written by Mr. D. H. Follett, of the Science Museum (at the Museum, or from the Institute of Physics, 1s. 2d. post paid); the first part is a guide to the exhibition and the second is a general account of the subjects dealt with in the various sections of the exhibition.
