Dr A.R. Michaelis said that when asked to give this talk he had regarded it as a challenge, because we live today in the second of the important revolutions which have occurred since science began to be properly used. The first revolution, the Industrial Revolution, helped man to get rid of manual drudgery, whereas the second and present one, the ‘Informational Revolution’, was about to do the same for the mental effort of mankind. The film had a most important part to play in the informational revolution, and he hoped to bring out some of the ways in which it could do so. The film was by no means properly used in this context at present, and further means and money would have to be made available before it could be used as it should be.
