How to Solve It
Gyorgy Polya
This perennial best seller was written by an
eminent mathematician, but it is a book for the general reader
on how to think straight in any field. In lucid and appealing
prose, it shows how the mathematical method of demonstrating a
proof or finding an unknown can be of help in attacking any problem
that can be "reasoned" out from building a bridge to winning a
game of anagrams. Generations of readers have relished G. Polya's
deft--indeed, brilliant--instructions on stripping away irrelevancies
and going straight to the heart of the problem.
