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.

This “enjoyable” biography of the brilliant astronomer will intrigue young people who are “bored with the textbook approach to science” (The New York Times Book Review). Sixteenth century Italy produced Galileo, a genius who marked the world with his studies and hypotheses about mathematical, physical, and astronomical truths. His father, musician Vincenzio Galilei said, “Truth is not found behind a man’s reputation. Truth appears only when the answers to questions are searched out by a free mind. This is not the easy path in life but it is the most rewarding.” Galileo challenged divine law and the physics of Aristotle, and questioned everything in search of truths. And it was through this quest for truth that he was able to establish a structure for modern science.

The award-winning New York Times bestseller about the extraordinary things that can happen when we harness the power of both the brain and the heart Growing up in the high desert of California, Jim Doty was poor, with an alcoholic father and a mother chronically depressed and paralyzed by a stroke. Today he is the director of the Center for Compassion and Altruism Research and Education (CCARE) at Stanford University, of which the Dalai Lama is a founding benefactor. But back then his life was at a dead end until at twelve he wandered into a magic shop looking for a plastic thumb. Instead he met Ruth, a woman who taught him a series of exercises to ease his own suffering and manifest his greatest desires. Her final mandate was that he keep his heart open and teach these techniques to others. She gave him his first glimpse of the unique relationship between the brain and the heart. Doty would go on to put Ruth’s practices to work with extraordinary results—power and wealth that he could only imagine as a twelve-year-old, riding his orange Sting-Ray bike. But he neglects Ruth’s most important lesson, to keep his heart open, with disastrous results—until he has the opportunity to make a spectacular charitable contribution that will virtually ruin him. Part memoir, part science, part inspiration, and part practical instruction, Into the Magic Shop shows us how we can fundamentally change our lives by first changing our brains and our hearts.

Modern Magic by Professor Hoffmann was one of the first books published in English on the art of conjuring during the Victorian era. Hoffmann was considered to be one of the greatest authorities on the theory and practice of magic at that time. This hardcover edition is a facsimile of the 1876 edition and whist some parts of the text are faded, it perfectly readable and makes a beautiful addition to any magician or historian's library.
