What two things could be more different than numbers and stories? Numbers are abstract, certain, and eternal, but to most of us somewhat dry and bloodless. Good stories are full of life: they engage our emotions and have subtlety and nuance, but they lack rigor and the truths they tell are elusive and subject to debate. As ways of understanding the world around us, numbers and stories seem almost completely incompatible.
Once Upon a Number shows that stories and numbers aren’t as different as you might imagine, and in fact they have surprising and fascinating connections. The concepts of logic and probability both grew out of intuitive ideas about how certain situations would play out. Now, logicians are inventing ways to deal with real world situations by mathematical means—by acknowledging, for instance, that items that are mathematically interchangeable may not be interchangeable in a story. And complexity theory looks at both number strings and narrative strings in remarkably similar terms.
Throughout, renowned author John Paulos mixes numbers and narratives in his own delightful style. Along with lucid accounts of cutting-edge information theory we get hilarious anecdotes and jokes; instructions for running a truly impressive pyramid scam; a freewheeling conversation between Groucho Marx and Bertrand Russell (while they’re stuck in an elevator together); explanations of why the statistical evidence against OJ Simpson was overwhelming beyond doubt and how the Unabomber’s thinking shows signs of mathematical training; and dozens of other treats. This is another winner from America’s favorite mathematician.

An adventurous ride through the most blisteringly hot regions of science, history, and culture.
Melting glaciers, warming oceans, droughts-it's clear that today's world is getting hotter. But while we know the agony of a sunburn or the comfort of our winter heaters, do we really understand heat?
A bestselling scientist and nature writer who goes to any extreme to uncover the answers, Bill Streever sets off to find out what heat really means. Let him be your guide and you'll firewalk across hot coals and sweat it out in Death Valley, experience intense fever and fire, learn about the invention of matches and the chemistry of cooking, drink crude oil, and explore thermonuclear weapons and the hottest moment of all time-the big bang.
Written in Streever's signature spare and refreshing prose, HEAT is an adventurous personal narrative that leaves readers with a new vision of an everyday experience-how heat works, its history, and its relationship to daily life.

From avalanches to glaciers, from seals to snowflakes, and from Shackleton's expedition to "The Year Without Summer," Bill Streever journeys through history, myth, geography, and ecology in a year-long search for cold--real, icy, 40-below cold. In July he finds it while taking a dip in a 35-degree Arctic swimming hole; in September while excavating our planet's ancient and not so ancient ice ages; and in October while exploring hibernation habits in animals, from humans to wood frogs to bears.
A scientist whose passion for cold runs red hot, Streever is a wondrous guide: he conjures woolly mammoth carcasses and the ice-age Clovis tribe from melting glaciers, and he evokes blizzards so wild readers may freeze--limb by vicarious limb.
