The revolution in the teaching of mathematics at schools and colleges is now well established. Not only have the methods of teaching changed considerably, but so have the topics which are taught. This is as it should be—the needs of our future mathematicians and scientists; are constantly changing in the light of the technical developments of the twentieth century. It seems likely that the frontiers of science will be pushed further and further back in the coming years and the mathematics required must certainly keep abreast of these changes.
