"Constant Companion": Review of *Gamma: Exploring Euler's Constant,* byJulian Havil. Reviewed by Ben Longstaff. New Scientist, 19 July 2003, page51.

There have been books about pi and about i, the square root of minus one. Thisis a book about one of those numbers' less famous but no less fascinatingbrethren called gamma. "Although the maths is at upper-undergraduate level,Havil's emphasis on historical context and his conversational style make this apleasure to read," the reviewer writes. "Anyone with a serious interest inmaths will find it richly rewarding."
