Over a period of 25 years as author of the Mathematical Games column for Scientific American, Martin Gardner devoted a column every six months or so to short math problems or puzzles. He was especially careful to present new and unfamiliar puzzles that had not been included in such classic collections as those by Sam Loyd and Henry Dudeney. Later, these puzzles were published in book collections, incorporating reader feedback on alternate solutions or interesting generalizations.
The present volume contains a rich selection of 70 of the best of these brain teasers, in some cases including references to new developments related to the puzzle. Now enthusiasts can challenge their solving skills and rattle their egos with such stimulating mind-benders as The Returning Explorer, The Mutilated Chessboard, Scrambled Box Tops, The Fork in the Road, Bronx vs. Brooklyn, Touching Cigarettes, and 64 other problems involving logic and basic math. Solutions are included.

"Although we are amused, we may also be embarrassed to find our friends or even ourselves among the gullible advocates of plausible-sounding doubletalk." — Saturday Review
"A very able and even-tempered presentation." — New Yorker
This witty and engaging book examines the various fads, fallacies, strange cults, and curious panaceas which at one time or another have masqueraded as science. Not just a collection of anecdotes but a fair, reasoned appraisal of eccentric theory, it is unique in recognizing the scientific, philosophic, and sociological-psychological implications of the wave of pseudoscientific theories which periodically besets the world.
To this second revised edition of a work formerly titled In the Name of Science, Martin Gardner has added new, up-to-date material to an already impressive account of hundreds of systematized vagaries. Here you will find discussions of hollow-earth fanatics like Symmes; Velikovsky and wandering planets; Hörbiger, Bellamy, and the theory of multiple moons; Charles Fort and the Fortean Society; dowsing and the other strange methods for finding water, ores, and oil. Also covered are such topics as naturopathy, iridiagnosis, zone therapy, food fads; Wilhelm Reich and orgone sex energy; L. Ron Hubbard and Dianetics; A. Korzybski and General Semantics. A new examination of Bridey Murphy is included in this edition, along with a new section on bibliographic reference material.

"[Gardner] zaps his targets with laserlike precision and wit."—Entertainment Weekly

Martin Gardner is perhaps the wittiest, most devastating unmasker of scientific fraud and intellectual chicanery of our time. Here he muses on topics as diverse as numerology, New Age anthropology, and the late Senator Claiborne Pell's obsession with UFOs, as he mines Americans' seemingly inexhaustible appetite for bad science. Gardner's funny, brilliantly unsettling exposés of reflexology and urine therapy should be required reading for anyone interested in "alternative" medicine. In a world increasingly tilted toward superstition, Did Adam and Eve Have Navels? will give those of us who prize logic and common sense immense solace and inspiration. "Gardner is a national treasure...I wish [this] could be made compulsory reading in every high school—and in Congress."—Arthur C. Clarke "Nobody alive has done more than Gardner to spread the understanding and appreciation of mathematics, and to dispel superstition."— The New Criterion, John Derbyshire
