Mathematics is the language of definiteness, the necessary vocabulary of those who know, hence the intimate connection between mathematics and science.
The tendency to select the problems and illustrations of mathematics mostly from the scientific, commercial and industrial activities of to-day, is one with which the writer is in accord. It may seem that in the following pages puzzles have too largely taken the place of problems.
But this is not a text-book. Moreover, amusement is one of the fields of applied mathematics.
