This book contains scores of intriguing puzzles and paradoxes from Lewis Carroll, the author of Alice in Wonderland, whose interests ranged from inventing new games like Arithmetical Croquet to important problems in symbolic logic and propositional calculus. Written by Carroll expert and well-known mathematics author Martin Gardner, this tour through Carroll's inventions is both fun and informative.

Martin Gardner, the "Mathematical Games" columnist for Scientific American from 1956 to 1981, was also a philosopher, polymath, magician, religious thinker, and the author of more than 70 books, including The Annotated Alice, The Ambidextrous Universe, and Visitors from Oz. Here his life and works are celebrated in a bouquet of essays about him or in his honor. Introduced by his son Jim, the book includes reminiscences by Douglas Hofstadter, Morton N. Cohen, Scott Kim, David Singmaster, Michael Patrick Hearn, and many others; a festschrift contains essays by such writers as Raymond Smullyan and Robin Wilson. This volume also contains the final annotations Gardner made to the Alice books post-"Definitive Edition," and a definitive bibliography of his Carroll-related writings. While put together under the aegis of the Lewis Carroll Society of North America, it takes a far broader look at this remarkable man and his many interests and accomplishments.

Published in 1955 under the direction of psychiatrist William Sadler, "The Urantia Book" is the largest and most sophisticated work of New Age literature ever produced. This massive tome is believed by devotees to be a revelation to our world, which is allegedly called 'Urantia' in the language of the unseen higher beings credited with inspiring the book. Unlike other channelled 'bibles', "The Urantia Book" contains a vast amount of modern science as well as an extensive biography of Jesus Christ, filled with details not found in the Gospels. Well-known sceptic and acclaimed popular science writer Martin Gardner presents a complete history of the Urantia movement, from its beginnings in the early 20th century to the present day.In addition to providing an outline of the Urantia cult's worldview, Gardner presents strong evidence to establish the identity of the man whose trance-like orations formed the basis of the book. Gardner also analyzes the flaws in Urantian science and points out many instances of plagiarism in various sections of the book. In a new postscript to this paperback edition, Gardner details recent developments in the Urantia movement, corrects some errors in the original edition, and responds to critical reactions from Urantia believers to his sceptical perspective on the book and the movement. Although there are other histories of "The Urantia Book", this is the only one written by a sceptic. Anyone interested in the New Age, cults, or the development of new religions will find much fascinating material in Gardner's thorough overview.

For more than twenty-five years, Martin Gardner was "Scientific American's" renowned provocateur of popular math. His yearly gatherings of short and inventive problems were easily his most anticipated math columns. Loyal readers would savor the wit and elegance of his explorations in physics, probability, topology, and chess, among others. Grouped by subject and arrayed from easiest to hardest, the puzzles gathered here, which complement the lengthier, more involved problems in "The Colossal Book of Mathematics," have been selected by Gardner for their illuminating; and often bewildering; solutions. Filled with over 300 illustrations, this new volume even contains nine new mathematical gems that Gardner, now ninety, has been gathering for the last decade. No amateur or expert math lover should be without this indispensable volume; a capstone to Gardner's seventy-year career.

A powerful tale of betrayal, trickery and sheer human grit from a dream-team of authors In a fight outside a bar Ramon Espejo kills a man. Next day, all hell breaks loose. The dead man was a big shot, a diplomat on a mission to the out-world of Sao Paulo. Ramon goes on the run, heading north toward unexplored territory, land so far only glimpsed from orbit during the first colony surveys. Ramon has gone from being nothing in the hills of Mexico to being nothing on Sao Paulo. He makes a bare living prospecting for minerals. Maybe God meant him to be poor, or he wouldn't have made him so mean. He can't even remember why he killed the European, only the drinking, and the rage that followed. Better to be alone in the wild landscape ... off the map, beyond law and civilization. Each trip out he's sure will be the big one that'll make him rich. This one, too. Instead he finds something else, something terrifying. Or rather, it finds him, and uses him: as humans are used by species more intelligent than themselves. But Ramon Espejo is about to prove what a man is capable of. Ramon is about to demonstrate what it is to be human; to be angry, intelligent and alive. And he is about to discover his function in the broad flow of the universe. And why it was he killed the diplomat in the first place...

In this lively collection, Gardner examines the rich and hilarious variety of pseudoscientific conjectures that dominate the media today. With a special emphasis on parapsychology and occultism, these witty pieces address the evidence put forth to support claims of ESP, psychokinesis, faith healing, and other pseudoscience.

The Magic Numbers of Dr. Matrix draws us into the intriguing and fascinating world of numbers and number theory. "Numbers, you know, have a mysterious life of their own. It would be naive," claims Dr. Matrix, "to suppose that there is such a thing as a randomly arranged group of symbols." Consider, for example, the decimal expansion of pi. Long considered a random series, it is actually rich with remarkable patterns. "Correctly interpreted," says Dr. Matrix, "pi conveys the entire history of the human race." Dr. Matrix uncovers patterns and signs that will astound you. As Dr. Matrix demonstrates, we need only look to find clues all around us in number and language "coincidences" that will unlock the mysteries of the universe. In The Magic Numbers of Dr. Matrix, Martin Gardner introduces us to this extraordinary man, Dr. Irving Joshua Matrix. Believed by many to be the greatest numerologist who ever lived, Dr. Matrix claims to be a reincarnation of Pythagoras. He was, however, completely unknown to the scientific community until Gardner wrote about him in Scientific American in 1960. That first report and the subsequent ones that appeared with each new encounter are collected here in their entirety. We follow Dr. Matrix as he roams the world and assumes new identities and discovers new manifestations of the power of numbers to explain and predict and entertain. Always at his side is his beautiful Eurasian daughter, Iva, who abets and protects her father in each new adventure. As you delve into The Magic Numbers of Dr. Matrix, you will master some significant combinatorial mathematics and number theory. The many remarkable puzzles of Dr. Matrix are all clearly answered in the back of the book, together with commentary and references by Gardner to enlighten the uninitiated and entertain the inquiring reader.

Whether discussing hexaflexagons or number theory, Klein bottles or the essence of "nothing," Martin Gardner has single-handedly created the field of "recreational mathematics." The Colossal Book of Mathematics collects together Gardner's most popular pieces from his legendary "Mathematical Games" column, which ran in Scientific American for twenty-five years. Gardner's array of absorbing puzzles and mind-twisting paradoxes opens mathematics up to the world at large, inspiring people to see past numbers and formulas and experience the application of mathematical principles to the mysterious world around them. With articles on topics ranging from simple algebra to the twisting surfaces of Mobius strips, from an endless game of Bulgarian solitaire to the unreachable dream of time travel, this volume comprises a substantial and definitive monument to Gardner's influence on mathematics, science, and culture. In its twelve sections, The Colossal Book of Math explores a wide range of areas, each startlingly illuminated by Gardner's incisive expertise. Beginning with seemingly simple topics, Gardner expertly guides us through complicated and wondrous worlds: by way of basic algebra we contemplate the mesmerizing, often hilarious, linguistic and numerical possibilities of palindromes; using simple geometry, he dissects the principles of symmetry upon which the renowned mathematical artist M. C. Escher constructs his unique, dizzying universe. Gardner, like few thinkers today, melds a rigorous scientific skepticism with a profound artistic and imaginative impulse. His stunning exploration of "The Church of the Fourth Dimension," for example, bridges the disparate worlds of religion and science by brilliantly imagining the spatial possibility of God's presence in the world as a fourth dimension, at once "everywhere and nowhere." With boundless wisdom and his trademark wit, Gardner allows the reader to further engage challenging topics like probability and game theory which have plagued clever gamblers, and famous mathematicians, for centuries. Whether debunking Pascal's wager with basic probability, making visual music with fractals, or uncoiling a "knotted doughnut" with introductory topology, Gardner continuously displays his fierce intelligence and gentle humor. His articles confront both the comfortingly mundane—"Generalized Ticktacktoe" and "Sprouts and Brussel Sprouts"—and the quakingly abstract—"Hexaflexagons," "Nothing," and "Everything." He navigates these staggeringly obscure topics with a deft intelligence and, with addendums and suggested reading lists, he informs these classic articles with new insight. Admired by scientists and mathematicians, writers and readers alike, Gardner's vast knowledge and burning curiosity reveal themselves on every page. The culmination of a lifelong devotion to the wonders of mathematics, The Colossal Book of Mathematics is the largest and most comprehensive math book ever assembled by Gardner and remains an indispensable volume for the amateur and expert alike.
