Description
In In Pursuit of the Unknown, celebrated mathematician Ian Stewart uses a handful of mathematical equations to explore the vitally important connections between math and human progress. We often overlook the historical link between mathematics and technological advances, says Stewart--but this connection is integral to any complete understanding of human history.

Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents--from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity--within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.

An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

Critical Reviews

"An engaging tour of vital math for a modern world.... [A] wonderfully accessible book."--Scientific American

"Stewart is the finest living math popularizer-a writer who can tackle eye-spraining mathematical topics approachably, and yet dazzle hard-core nerds with new and surprising information. It is hard not to get your money's worth from him, and in a book like this he is at his best because of the very wide ground covered."--Maclean's

"Seemingly basic equations have enabled us to predict eclipses, engineer earthquake-proof buildings, and invent the refrigerator. In this lively volume, mathematician Ian Stewart delves into 17 equations that shape our daily existence, including those dreamed up by the likes of Einstein, Newton, and Erwin Schrödinger."--Discover

"Stewart shares his enthusiasm as well as his knowledge in this tour of ground-breaking equations and the research they supported.... An entertaining and illuminating collection of curious facts and histories suitable for random dipping-in or reading straight through."--Publishers Weekly

"Stewart provides clear, cogent explanations of how the equations work without burdening the reader with cumbersome derivations.... He gives a fascinating explanation of how Newton's laws, when extended to three-body problems, are still used by NASA to calculate the best route from Earth to Mars and have laid the basis for chaos theory. Throughout, Stewart's style is felicitous."--Kirkus Reviews

"Stewart's expertise and his well-developed style (enhanced by a nice sense of humor) make for enjoyable reading.... [A] worthwhile and entertaining book, accessible to all readers. Recommended for anyone interested in the influence of mathematics on the development of science and on the emergence of our current technology-driven society."--Library Journal

"Stewart has managed to produce a remarkably readable, informative and entertaining volume on a subject about which few are as well informed as they would like to be."--Washington Independent Review of Books

"Stewart is a genius in the way he conveys his excitement and sense of wonder.... He has that valuable grasp of not only what it takes to make equations interesting, but also to make science cool."--New York Journal of Books

"Nothing less than a quick tour of the history of scientific thought, from ancient Greece to quantum mechanics and beyond."--Times Higher Education Supplement

"An interesting and highly entertaining book."--Physics Today

"[An] engaging work...An entertaining journey through the development of theoretical mathematics, as well as an informative look at applied science."--Booklist

"If you were a mathlete or have even the slightest interest in figures, Ian Stewart can bring the subject alive for you."--History Wire

"Ian Stewart has penned a book for both sides of the divide with In Pursuit of the Unknown, ably bridging the gap between those daunted and undaunted by the language of equations."--Tulsa Book Review
