Princeton University Press The Altruism Equation: Seven Scientists Search for the Origins of Goodness

If you've ever wondered why parents do stuff for their children or why you feel responsible for people who you don't know that well or just wonder why humanity in general works so damn well interacting with each other, then this is the book for you!It is very scientific and the stories and biographies that are told are interesting.

An interesting collection of short related stories, but scarcely a mention of the actual equation, which is really trivial, or its development. Pity - a lost opportunity.A future edition could usefully include a few math appendices so the average scientist can see what all the fuss is about.
