In March 2006, the world’s richest men sipped champagne in an opulent New York hotel. They were preparing to compete in a poker tournament with ­million-dollar stakes. At the card table that night was Peter Muller, who managed a fabulously successful hedge fund called PDT. With him was Ken Griffin, who was the tough-as-nails head of Citadel Investment Group. There, too, were Cliff Asness, the sharp-tongued, mercurial founder of the hedge fund AQR Capital Management, and Boaz Weinstein, chess “life master” and king of the credit-default swap.

For thousands of years mathematicians solved progressively more difficult algebraic equations, until they encountered the quintic equation, which resisted solution for three centuries. Working independently, two prodigies ultimately proved that the quintic cannot be solved by a simple formula. The first popular account of the mathematics of symmetry and order, The Equation That Couldn't Be Solved is told not through abstract formulas but in a beautifully written and dramatic account of the lives and work of some of the greatest and most intriguing mathematicians in history.

Once you know how to see them, numbers are all around us - buried in the dimensions of buildings and encoding the data on our favourite gadgets. They’re a beautiful system of patterns and codes but also an essential tool that can guide our daily decisions, change our behaviour and even predict the future - if we can just learn how to use them right.

Four friends’ carefree lives in London are shattered when a strange virus sweeps through the city, turning familiar faces into mindless threats.

Winston is in trouble. He didn’t bring his math homework to school, and his teacher isn’t happy! It wasn’t his fault, though. He’d been chewing bubblegum and blowing bubbles, and one of his bubbles goes on an adventure—and takes his homework with it!

We can learn many things from models. Scientists use models to test their ideas. Listeners will learn about the importance of making predictions, testing ideas, collecting data, and more.

Survival Math is both a personal reckoning and a vital addition to the national conversation about race. Mitchell explores the Portland of his childhood, tracing the ways in which his family managed their lives in and around drugs, prostitution, gangs, and imprisonment as members of a tiny black population in one of the country’s whitest cities. He discusses sex work and serial killers, gangs and guns, near-death experiences, composite fathers, the concept of “hustle,” and the destructive power of drugs and addiction on family.

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books.

When Alex Stone was five years old, his father bought him a magic kit - a gift that would spark a lifelong love. Years later, while living in New York City, he discovered a vibrant underground magic scene exploding with creativity and innovation and populated by a fascinating cast of characters: from his gruff mentor, who holds court in the back of a rundown pizza shop, to one of the world's greatest card cheats, who also happens to be blind. Captivated, he plunged headlong into this mysterious world.

Math is famous for its equations: 1 + 1 = 2, a^2 + b^2 = c^2, or y = mx + b. Much of the time it can seem like that’s all mathematics is: following steps to show that what’s on one side of an equation is the same as what’s on the other. In Unequal, Eugenia Cheng shows that’s just part of the story, and the boring part to boot. It isn’t even just about numbers and symbols at all, but a world of shapes, symmetries, logical ideas, and more.
