A terrific cognitive romp through some of the most important puzzlers, challenges, sizzlers and stumpers throughout history.This new book fills that gap, covering a large number of things never envisioned by Gaines; including hill climbing, the best known contemporary algorithm for breaking ciphers. It captures the harsh realities of life for those who spent the war in less lauded, yet equally important, secret roles. Code experts and enthusiasts Elonka Dunin and Klaus Schmeh patiently explain the basic types of codes and ciphers, and how to detect which scheme is being used. Hmmm…Should we allow parents, if they can afford it, to enhance the height or muscles or IQ of their kids?
