Why is math so hard? And why, despite this difficulty, are some people so good at it? If there's some inborn capacity for mathematical thinking,which there must be, otherwise no one could do it ,why can't we all do it well? Keith Devlin has answers to all these difficult questions, and in giving them shows us how mathematical ability evolved, why it's a part of language ability, and how we can make better use of this innate talent.He also offers a breathtakingly new theory of language development,that language evolved in two stages, and its main purpose was not communication,to show that the ability to think mathematically arose out of the same symbol-manipulating ability that was so crucial to the emergence of true language. Why, then, can't we do math as well as we can speak? The answer, says Devlin, is that we can and do,we just don't recognize when we're using mathematical reasoning.

Why do leopards grow spots when tigers grow stripes? Is the universe round, square, or some other shape? How do the dimples in a golf ball give it greater lift? Is there such a thing as a public mood? If so, how can we accurately take its pulse?Only one tool of the human mind has the power and versatility to answer so many questions about our world—mathematics. Far from a musty set of equations and proofs, mathematics is a vital and creative way of thinking and seeing. It is the most powerful means we have of exploring our world and how it works, from the darkest depths of the oceans to the faintest glimmers of far-away galaxies, and from the aerodynamics of figure-skating jumps to the shadows of the fourth dimension.In this captivating companion to the landmark PBS series Life by the Numbers, acclaimed author Keith Devlin reveals the astonishing range of creative and powerful ways in which scientists, artists, athletes, medical researchers, and many others are using mathematics to explore our world and to enhance our lives.On this exhilarating tour you will explore deep-sea volcanoes with oceanographer Dawn Wright, go behind the scenes of blockbuster movies with special-effects designer Doug Trumbull, and probe the strange lives of viruses with microbiologist Sylvia Spengler. Listen to astronomer Robert Kirshner describe how he is charting the curve of space; discover how biologist Mike Labarbara visualizes the way a Tyrannosaurus rex carried its massive frame; and, along with brain researcher Brad Hatfield, peer into the mind of an Olympic markswoman at the moment she takes a shot. Glimpse a future of wearable computers and silicon "butlers" with computer scientist Pattie Maes, and watch a lilac come to life on screen with "computer botanist" Przemyslaw Prusinkiewicz.Lavishly illustrated and beautifully written, Life by the Numbers brings mathematical exploration and invention to life through the stories of some of the most creative practitioners of the art. It imparts an appreciation of the ingenuity and the sheer fun of seeing our world through mathematical eyes.

Do you expect to find articles about mathematics in your daily newspaper? If you are a reader of The Guardian you do, or at least you did during the second half of the 1980s. This volume collects many of the columns Keith Devlin wrote for The Guardian. Read them and assign them to your students to read. This is a book for delving in, and is accessible to anyone with an interest in things mathematical. Devlin takes mathematical discoveries and explains them to the interested lay reader. The topics range from computer discoveries dealing with large prime numbers to much deeper results, such as Fermat's Last Theorem. You will find articles on the traveling salesman problem, on cryptology, and on procedures for working out claims for traveling expenses. Although the individual pieces are short and easily read, many contain references to mathematical articles and can form the basis for student research papers.
