9780486229492: The Gentle Art of Mathematics

This lighthearted work uses a variety of practical applications and puzzles to take a look at today's mathematical trends. In nine chapters, Professor Pedoe covers mathematical games; chance and choice; where does it end; automatic thinking; two-way stretch; rules of play; an accountant's nightmare; and double talk. Practical examples and problems are featured throughout.
