Оказывается, позициям в самых разных играх можно сопоставить своеобразные числа, оценивающие положение игроков. Возникающие «сюрреальные числа» включают в себя все действительные числа (но не только). В брошюре рассказывается, как возникающая теория помогает проанализировать ним, хакенбуш и другие игры.

Из этой книги читатель узнает, как решать алгебраические уравнения 3-й и 4-й степени с одним неизвестным и почему для решения уравнений более высокой степени не существует общих формул (в радикалах). При этом он познакомится с двумя очень важными разделами современной математики – теорией групп и теорией функций комплексного переменного. Одна из основных целей данной книги – дать возможность читателю попробовать свои силы в математике. Для этого почти весь материал представлен в виде определений, примеров и большого числа задач, снабженных указаниями и решениями.

Learn geometry at your own pace What are congruent circles? How do you find the hypotenuse of a triangle? What is the sum of the angles in a decagon? How can you apply geometric equations to your daily life? With the unbeatable study companion Geometry: A Self-Teaching Guide, you'll discover the answers to these questions and many more. This thorough primer presents an easy-to-follow, proven method for grasping the key concepts of geometry. You'll progress step by step through plane, solid, and analytic geometry and then move on to geometric applications for calculus. You'll build your problem-solving skills along the way through detailed examples, reviews, exercises, and answer explanations. The clearly structured format of Geometry makes it fully accessible, providing an easily understood, comprehensive overview for everyone from high school students to adult learners to math mavens. Like all Self-Teaching Guides, Geometry allows you to build gradually on what you have learned-at your own pace. Questions and self-tests reinforce the information in each chapter and allow you to skip ahead or focus on specific areas of concern. Packed with useful, up-to-date information, this clear, concise volume is a valuable learning tool and reference source for anyone who wants to improve his or her understanding of basic geometry.

A mind-bending excursion to the limits of science and mathematics Are some scientific problems insoluble? In Beyond Reason, internationally acclaimed math and science author A. K. Dewdney answers this question by examining eight insurmountable mathematical and scientific roadblocks that have stumped thinkers across the centuries, from ancient mathematical conundrums such as «squaring the circle,» first attempted by the Pythagoreans, to G?del's vexing theorem, from perpetual motion to the upredictable behavior of chaotic systems such as the weather. A. K. Dewdney, PhD (Ontario, Canada), was the author of Scientific American's «Computer Recreations» column for eight years. He has written several critically acclaimed popular math and science books, including A Mathematical Mystery Tour (0-471-40734-8); Yes, We Have No Neutrons (0-471-29586-8); and 200% of Nothing (0-471-14574-2).
