A perennial bestseller by eminent mathematician G. Polya, How to Solve It will show anyone in any field how to think straight. In lucid and appealing prose, Polya reveals 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 Polya's deft--indeed, brilliant--instructions on stripping away irrelevancies and going straight to the heart of the problem.… (mer)

Polya was more general than I would have liked, without a lot of examples that related to what I was trying to learn.
The best lesson i learned from this work was to first try to understand the problem before slogging into it with some random sort of method. ( )

I'm conflicted about this book. There is a lot of good advice around the art of problem solving, but my god is there a lot of shit too. The layout is mostly a big alphabetical glossary of _math things_ --- everything from leading questions to notions of symmetry to anecdotes about absentminded professors --- and the layout doesn't particularly help. It's not organized by topic or ordered by first things first, it's just plopped down alphabetically. As such, it's hard to get into the flow.

This book however is lacking primarily in that it deals with how to solve "well-posed questions," which is to say, toy problems. There is very little about conducting your own open-ended research, and about how to turn wisps of ideas into well-posed ones. ( )

How to Solve It is decent, but overrated – the first 10% are pretty good, and then there are a few nuggets of really good advice interspersed with the neverending examples of the principles introduced in the first part. ( )

I came across this book as a result of my entry into Mathematics. If you have read enough Philosophy and question your own assumptions, ideas, you'll find the ideas in this book are repetitive. I would recommend this book to someone who wants to know basic problem-solving skills.

[5 out of 5] My only regret is that I must return this book to the library. This is one of those rare books I recommend to pretty much anyone who has to deal with problem solving.

Not just mathematical problems, though. Polya writes an excellent case for the way we all should approach problems. It's not a formula, rather a scaffolding for thought, strategies for learning and teaching, reflections on successful solving and common pitfalls. If you want to think like a scientist, this is an excellent start, whether you have a science degree/background or not ( )

(Preface to the First Printing); A great discovery solves a great problem but there is a grain of disovery in the solution of any problem.
(Preface to the Second Edition): The present second edition adds, besides a few minor improvements, a new fourth part, "Problems, Hints, Solutions."
(Foreword by John H. Conway): How to Solve It is a wonderful book!
(Introduction): The following considerations are grouped around the preceding list of questions and suggestions entitled "How to Solve It."
