User Review - Razinha - LibraryThingWonderful book. Boole and Turing, abacus math, optical illusions, palindromes, compass geometry, rotations, triangles, randomness, lots of numbers and other problems. And I confess to never having thought about hyperspheres before reading this book. One of his better collections. Read full review
