ABSTRACT
Mathematics is essential for science. This seems so obvious to me. This is especially true in physics, in the theoretical and physical branches of chemistry and also in the applications of statistics in hypotheses-testing in biology. Things that seem so obvious mean that they can be overlooked. In one department where I worked, the entry requirements by subject for incoming students did not include mathematics as essential. My campaign to require this was not successful, even though similar departments at other front-ranked universities like mine had this requirement. Let me emphasise the importance of mathematics in science with just a few examples.
