“Where else does math become a romp, full of entertaining tricks and turns?”—Bryce Christensen, Booklist Have you ever considered why you always get stuck in the longest line? Why two’s company but three’s a crowd? Or why there are six degrees of separation instead of seven? In this hugely informative and endlessly entertaining book, John D. Barrow takes the most baffling of everyday phenomena and—with simple math, lucid explanations, and illustrations—explains why they work the way they do. His witty, crystal-clear answers shed light on the dark and shadowy corners of the physical world we all think we understand so well.

In How Math Explains the World, mathematician Stein reveals how seemingly arcane mathematical investigations and discoveries have led to bigger, more world-shaking insights into the nature of our world. In the four main sections of the book, Stein tells the stories of the mathematical thinkers who discerned some of the most fundamental aspects of our universe. From their successes and failures, delusions, and even duels, the trajectories of their innovations—and their impact on society—are traced in this fascinating narrative. Quantum mechanics, space-time, chaos theory and the workings of complex systems, and the impossibility of a "perfect" democracy are all here. Stein's book is both mind-bending and practical, as he explains the best way for a salesman to plan a trip, examines why any thought you could have is imbedded in the number p , and—perhaps most importantly—answers one of the modern world's toughest questions: why the garage can never get your car repaired on time. Friendly, entertaining, and fun, How Math Explains the World is the first book by one of California's most popular math teachers, a veteran of both "math for poets" and Princeton's Institute for Advanced Studies. And it's perfect for any reader wanting to know how math makes both science and the world tick.

Math, so often a mystery to children, is simply explained in I Wish I Knew That Math. With clear, commonsense explanations of mathematical concepts and fun and interesting applications, this book is a great way to increase your understanding of math. The concepts addressed include, but are certainly not limited to: Basic operations – addition, subtraction, multiplication and division The math behind money The connections between math and music Irrational numbers – Why did Pythagoras have one of his followers killed just for talking about the square root of 2? The value of zero Angles – from acute, all the way to reflexive Coordinates and the Cartesian plane Probability – What is the likelihood of being struck by lightning? Logic – induction, deduction and Sherlock Holmes Computers and algorithms Code breaking – from ancient Rome to super computers With its readable style and engaging examples, I Wish I Knew That: Math can give children a head start or a helping hand in their understanding of math. Even grownups could learn a thing or two that they may have forgotten or maybe things they never learned at all!

Barrow presents an unforgettable tour of the strange and wonderful universes that modern physics posits might--just might--be out there.

"The ancient Greeks argued that the best life was filled with beauty, truth, justice, play and love. The mathematician Francis Su knows just where to find them."--Kevin Hartnett, Quanta Magazine" This is perhaps the most important mathematics book of our time. Francis Su shows mathematics is an experience of the mind and, most important, of the heart."--James Tanton, Global Math Project For mathematician Francis Su, a society without mathematical affection is like a city without concerts, parks, or museums. To miss out on mathematics is to live without experiencing some of humanity's most beautiful ideas. In this profound book, written for a wide audience but especially for those disenchanted by their past experiences, an award-winning mathematician and educator weaves parables, puzzles, and personal reflections to show how mathematics meets basic human desires--such as for play, beauty, freedom, justice, and love--and cultivates virtues essential for human flourishing. These desires and virtues, and the stories told here, reveal how mathematics is intimately tied to being human. Some lessons emerge from those who have struggled, including philosopher Simone Weil, whose own mathematical contributions were overshadowed by her brother's, and Christopher Jackson, who discovered mathematics as an inmate in a federal prison. Christopher's letters to the author appear throughout the book and show how this intellectual pursuit can--and must--be open to all.
