bit-player is a blog authored by Brian Hayes that I read occasionally. That's where I learnt about his latest book Group Theory In The Bedroom, And Other Mathematical Diversions. It's a compilation of 12 long essays he had written for the American Scientist magazine. Written for a general scientifically oriented audience, I found most of the chapters to be fun and interesting. Brian has the gift of making complex ideas easy to understand by using simple analogies. He also researches in-depth into the history behind the science, this is something I sorely miss in most math/science writing. The humans and their stories are just as important as their ideas. This book is an interesting read.
