Every good reference book is both a product and a reflection of its time. The Dictionary of Magic & Mystery is not just another compendium or dictionary of occultism: it is a jumping-off point for further research. Here, the reader will find the ancient and modern interpretation for magical and mystical terms, together with explanations for the differences between the varied (and often conflicting) approaches to magic.

Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one--before Gardner--had written about mathematics like this. They continue to be a marvel. This volume is a collection of Irving Joshua Matrix columns published in the magazine from 1960-1980. There were several collections of Dr. Matrix, the first in 1967; they were revised as Gardner reconnected with the good doctor over the years. This is the 1985 Prometheus Books edition and contains all the Dr. Matrix columns from the magazine.

Whether you lived through the sixties and seventies or just wish you had, this revised and expanded edition of the Hippie Dictionary entertains as much as it educates. Cultural and political listings such as "Age of Aquarius," "Ceasar Chavez," and "Black Power Movement," plus popular phrases like "acid flashback," "get a grip," and "are you for real?" will remind you of how revolutionary those 20 years were. Although the hippie era spans two decades beginning with the approval of the birth control pill in 1960 and ending with the death of John Lennon in 1980, it wasn't all about sex, drugs, and rock'n' roll. These were the early years of pro-ecology and anti-capitalist beliefs-beliefs that are just as timely as ever. So kick back and trip out on the new entries as well as the old, and discover why some are dubbing the sixties and seventies "the intellectual renaissance of the 20th century."
