THE Association of Scientific Workers has organized a series of five public lectures under the general title “Science and Society”, to be given at University College, London, on successive Wednesdays, beginning February 17. The lectures cover a wide range of topics, and the whole series should prove of unusual interest to scientific workers. Prof. J. B. S. Haldane will talk on “Facts and Theories concerning Human Race Differences” on February 17, and the chairman on this occasion will be Sir F. Gowland Hopkins. On the following Wednesdays, the lecturers will be A. L. Bacharach on “Nutrition and Society”, Prof. H. Levy on “The Socialization of Mathematics”, Prof. P. M. S. Blackett, on “Physics” and Prof. Lancelot Hogben on “The Social Background of Science”. This is the first of an annual series of lectures on the general implications of science which the Association hopes to arrange. Further information and tickets (Is. for each lecture, 4s. for course of five) can be obtained from the Assistant Secretary, Association of Scientific Workers, Kelvin House, 28 Hogarth Road, S.W.5.
