The Number Mysteries: A Mathematical Odyssey through Everyday Life
From the author of The Music of the Primes and Finding Moonshine comes a short, lively book on five mathematical problems that just refuse be solved – and on how many everyday problems can be solved by maths.Every time we download a song from i-tunes, take a flight across the Atlantic or talk on our mobile phones, we are relying on great mathematical inventions. Maths may fail to provide answers to various of its own problems, but it can provide answers to problems that don't seem to be its own – how prime numbers are the key to Real Madrid's success, to secrets on the Internet and to the survival of insects in the forests of North America.In The Num8er My5teries, Marcus du Sautoy explains how to fake a Jackson Pollock; how to work out whether or not the universe has a hole in the middle of it; how to make the world's roundest football. He shows us how to see shapes in four dimensions – and how maths makes you a better gambler. He tells us about the quest to predict the future – from the flight of asteroids to an impending storm, from bending a ball like Beckham to predicting population growth.It's a book to dip in to; a book to challenge and puzzle – and a book that gives us answers.

Two - The Story of the Elusive Shape
Three - The Secret of the Winning Streak
Four - The Case of the Uncrackable Code
Is climate change a reality? Will the solar system suddenly fly apart? Is it safe to send your credit card number over the Internet? How can I beat the casino?
Ever since we’ve been able to communicate, we’ve been asking questions—trying to make predictions about what the future holds, negotiating the environment around us. The most powerful tool that humans have created to navigate the wild and complex world we live in is mathematics.
From predicting the trajectory of a football to charting the population of lemmings, from cracking codes to winning at Monopoly, mathematics has provided the secret language to unlock nature’s mysteries. But mathematicians don’t have all the answers. There are many deep and fundamental questions we are still struggling to crack.
In each chapter of The Number Mysteries I want to take you on a journey through the big themes of mathematics, and at the end of each chapter I will reveal a mathematical mystery that no one has yet been able to solve. These are some of the great unsolved problems of all time.
But solving one of these conundrums won’t just bring you mathematical fame—it will also bring you an astronomical fortune. An America businessman, Landon Clay, has offered a prize of a million dollars for the solution to each of these mathematical mysteries. You might think it strange that a businessman should want to hand out such big prizes for solving mathematical puzzles. But he knows that the whole of science, technology, the economy and even the future of our planet relies on mathematics.
Each of the five chapters of this book introduces you to one of these million-dollar puzzles.
Chapter 1, The Curious Incident of the Never Ending Primes, takes as its theme the most basic object of mathematics: number. I will introduce you to the primes, the most important numbers in mathematics but also the most enigmatic. A mathematical million awaits the person who can unravel their secrets.
In Chapter 2, The Story of the Elusive Shape, we take a journey through nature’s weird and wonderful shapes: from dice to bubbles, from tea bags to snowflakes. Ultimately we tackle the biggest challenge of them all—what shape is our universe?
Chapter 3, The Secret of the Winning Streak, will show you how the mathematics of logic and probability can give you the edge when it comes to playing games. Whether you like playing with Monopoly money or gambling with real cash, mathematics is often the secret to coming out on top. But there are some simple games that still fox even the greatest minds.
Cryptography is the subject of Chapter 4, The Case of the Uncrackable Code. Mathematics has often been the key to unscrambling secret messages. But I will reveal how you can use clever mathematics to create new codes that let you communicate securely across the Internet, send messages through space and even read your friend’s mind.
Chapter 5 is about what we would all love to able to do: The Quest to Predict the Future. I will explain how the equations of mathematics are the best fortune-tellers. They predict eclipses, explain why boomerangs come back and ultimately tell us what the future holds for our planet. But some of these equations we still can’t solve. The chapter ends with the problem of turbulence, which affects everything from David Beckham’s free-kicks to the flight of an aeroplane, yet it is still one of mathematics’ greatest mysteries.
