Abstract
THERE has been a considerable increase of interest recently in the use of films for mathematical teaching. The Mathematical Gazette of October 1938 and the American Mathematical Monthly of the same month both contain reviews of such films, but the majority of the films mentioned are not available in Great Britain. Mr. B. G. D. Salt, of 5 Carlingford Road, Hampstead, N.W.3, sends us a list of five films that are now available and can be obtained from him. Two of these are geometrical, dealing respectively with the theorem of Pythagoras concerning right-angled triangles, and with the sum of the angles of a triangle. Two others deal with differential equations,by a method devised by Robert Fairthorne, one for the differential equation of free harmonic motion, and the other for harmonic motion when the vibrations are forced. The principle for free vibrations was explained in NATURE of October 24, 1936, and that for forced vibrations is somewhat similar. These four films occupy one reel each.
