Bøker av Martin Gardner

Der Begriff des Spieles, der die Unterhaltungs mathematik erst unter- haltsam gestaltet, auert sich in vielen Formen: ein Ratsel, das gelost werden soll, ein Zweipersonenspiel, ein magischer Trick, ein Paradoxon, Trugschlusse oder ganz einfach Mathematik mit uberraschenden und amusanten Beigaben. Gehoren diese Beispiele nun zur reinen oder ange- wandten Mathematik? Es ist schwer zu sagen. Einerseits ist Unterhal- tungsmathematik reine Mathematik, unbeeinflut von der Frage nach den Anwendungsmoglichkeiten. Andererseits ist sie aber auch ange- wandte Mathematik, denn sie entstand aus dem allgemeinen menschli- chen Hang zum Spiel. Vielleicht steht dieser Hang zum Spiel aber auch hinter der reinen Mathe- matik. Besteht doch kein wesentlicher Unterschied zwischen dem Triumph eines Laien, der eine "e;harte Nu geknackt hat"e; und der Befriedigung, die ein Mathematiker empfindet, wenn er ein hoheres Problem gelost hat. Beide blicken auf die reine Schonheit - diese klare, exakt definiert, geheimnisvolle und uberwaltigende Ordnung, die jeder Struktur zugrunde liegt. Es ist daher nicht verwunderlich, da es oft auerst schwierig ist, die reine Mathematik von der Unterhaltungsmathematik zu unter- scheiden. Das VierfarbenproblemI) beispielsweise ist ein wichtiges bisher ungelos- tes Problem der Topologie und doch findet man Diskussionen uber dieses Problem in vielen unterhaltungsmathematischen Buchern.

This beautifully designed model account includes important new information which will not only be of great interest to botanists, conservationist and horticulturists but also to local people who are dependent on the diminishing natural habitats in central and southern Chile.

This book presents a collection of problems and puzzles, and provides the tools and projects to furnish all-too-sluggish minds with an athletic workout and which foster an agility of the mind as they entertain. It is dedicated to all the underpaid teachers of mathematics everywhere.

Best known as the longtime writer of the Mathematical Games column for Scientific American-which introduced generations of readers to the joys of recreational mathematics-Martin Gardner has for decades pursued a parallel career as a devastatingly effective debunker of what he once famously dubbed "fads and fallacies in the name of science." It is mainly in this latter role that he is onstage in this collection of choice essays.When You Were a Tadpole and I Was a Fish takes aim at a gallery of amusing targets, ranging from Ann Coulter's qualifications as an evolutionary biologist to the logical fallacies of precognition and extrasensory perception, from Santa Claus to The Wizard of Oz, from mutilated chessboards to the little-known "one-poem poet" Langdon Smith (the original author of this volume's title line). The writings assembled here fall naturally into seven broad categories: Science, Bogus Science, Mathematics, Logic, Literature, Religion and Philosophy, and Politics. Under each heading, Gardner displays an awesome level of erudition combined with a wicked sense of humor.

The Whys of a Philosophical Scrivener showcases Martin Gardner as the consummate philosopher, thinker, and great mathematician that he is. Exploring issues that range from faith to prayer to evil to immortality, and far beyond, Garnder challenges the discerning reader with fundamental questions of classical philosophy and life's greater meanings.Recalling such philosophers was Wittgenstein and Arendt, The Whys of Philosophical Scrivener embodies Martin Garner's unceasing interest and joy in the impenetrable mysteries of life.

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.

The autobiography of the beloved writer who inspired a generation to study math and scienceMartin Gardner wrote the Mathematical Games column for Scientific American for twenty-five years and published more than seventy books on topics as diverse as magic, religion, and Alice in Wonderland. Gardner's illuminating autobiography is a candid self-portrait by the man evolutionary theorist Stephen Jay Gould called our "e;single brightest beacon"e; for the defense of rationality and good science against mysticism and anti-intellectualism.Gardner takes readers from his childhood in Oklahoma to his varied and wide-ranging professional pursuits. He shares colorful anecdotes about the many fascinating people he met and mentored, and voices strong opinions on the subjects that matter to him most, from his love of mathematics to his uncompromising stance against pseudoscience. For Gardner, our mathematically structured universe is undiluted hocus-pocus-a marvelous enigma, in other words.Undiluted Hocus-Pocus offers a rare, intimate look at Gardner's life and work, and the experiences that shaped both.

Martin Gardner returns to charm readers with the latest on packing spheres, Reversi, braids, polyominoes, board games, and the puzzles of Lewis Carroll. Read about Knuth's Word Ladders program, new ways of finding the digits of pi, and much much more.

Well-known skeptic 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 trancelike 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 skeptical perspective on the book and the movement.Although there are other histories of The Urantia Book, this is the only one written by a skeptic.

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. This title follows Dr Matrix as he roams the world and assumes new identities and discovers new manifestations of the power of numbers to explain and predict.

First published in 1910, this text aims to make the topic of calculus accessible to students of mathematics. Gardner has updated the text to reflect developments in method and terminology, written an extensive preface and three new chapters, and added more than 20 recreational problems.
