Textbook in PDF format

The Puzzle Universe is intended for general readers and devoted puzzlers. It is about the latent beauty of mathematics, its history, and the puzzles that have advanced and emerged from the science of numbers. It is full of challenging historical facts, thinking puzzles, paradoxes, illusions, and problem solving.
There are 315 puzzles in this book. Extended captions explain in easy terms the value of the puzzles for mathematical and educational purposes, particularly in light of the findings of recent research. This historical and pedagogical dimension sets The Puzzle Universe apart from similar books.
The puzzles appear in a dynamic layout for a visual experience that is Ivan Moscovich's trademark. There are ten chapters complete with answers. Icons show the challenge rating and the tools needed (pencil, scissors, ruler, and of course, brain) to solve the puzzle.
