NEW YORK TIMES BESTSELLER“Marvelous . . . an array of witty and astonishing stories . . . to illuminate how calculus has helped bring into being our contemporary world.”—The Washington PostFrom preeminent math personality and author of The Joy of x, a brilliant and endlessly appealing explanation of calculus – how it works and why it makes our lives immeasurably better. Without calculus, we wouldn’t have cell phones, TV, GPS, or ultrasound. We wouldn’t have unraveled DNA or discovered Neptune or figured out how to put 5,000 songs in your pocket. Though many of us were scared away from this essential, engrossing subject in high school and college, Steven Strogatz’s brilliantly creative, down‑to‑earth history shows that calculus is not about complexity; it’s about simplicity. It harnesses an unreal number—infinity—to tackle real‑world problems, breaking them down into easier ones and then reassembling the answers into solutions that feel miraculous. Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves (a phenomenon predicted by calculus). Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes “backwards” sometimes; how to make electricity with magnets; how to ensure your rocket doesn’t miss the moon; how to turn the tide in the fight against AIDS. As Strogatz proves, calculus is truly the language of the universe. By unveiling the principles of that language, Infinite Powers makes us marvel at the world anew.

One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind themIn ancient times the Rings of Power were crafted by the Elven-smiths, and Sauron, the Dark Lord, forged the One Ring, filling it with his own power so that he could rule all others. But the One Ring was taken from him, and though he sought it throughout Middle-earth, it remained lost to him. After many ages it fell by chance into the hands of the hobbit Bilbo Baggins.From Sauron's fastness in the Dark Tower of Mordor, his power spread far and wide. Sauron gathered all the Great Rings to him, but always he searched for the One Ring that would complete his dominion.When Bilbo reached his eleventy-first birthday he disappeared, bequeathing to his young cousin Frodo the Ruling Ring and a perilous quest: to journey across Middle-earth, deep into the shadow of the Dark Lord, and destroy the Ring by casting it into the Cracks of Doom.The Lord of the Rings tells of the great quest undertaken by Frodo and the Fellowship of the Ring: Gandalf the Wizard; the hobbits Merry, Pippin, and Sam; Gimli the Dwarf; Legolas the Elf; Boromir of Gondor; and a tall, mysterious stranger called Strider.This new edition includes the fiftieth-anniversary fully corrected text setting and, for the first time, an extensive new index.J.R.R.

His chief interest was the linguistic aspects of the early English written tradition, but while he studied classic works of the past, he was creating a set of his own.

Best-selling author Tim O’Brien shares wisdom from a life in letters, lessons learned in wartime, and the challenges, humor, and rewards of raising two sons.“We are all writing our maybe books full of maybe tomorrows, and each maybe tomorrow brings another maybe tomorrow, and then another, until the last line of the last page receives its period.” In 2003, already an older father, National Book Award–winning novelist Tim O’Brien resolved to give his young sons what he wished his own father had given to him—a few scraps of paper signed “Love, Dad.” Maybe a word of advice. Maybe a sentence or two about some long-ago Christmas Eve. Maybe some scattered glimpses of their rapidly aging father, a man they might never really know. For the next fifteen years, the author talked to his sons on paper, as if they were adults, imagining what they might want to hear from a father who was no longer among the living. O’Brien traverses the great variety of human experience and emotion, moving from soccer games to warfare to risqué lullabies, from alcoholism to magic shows to history lessons to bittersweet bedtime stories, but always returning to a father’s soul-saving love for his sons. The result is Dad’s Maybe Book, a funny, tender, wise, and enduring literary achievement that will squeeze the reader’s heart with joy and recognition.

A PBS Great American Read Top 100 Pick With extraordinary relevance and renewed popularity, George Orwell’s 1984 takes on new life in this hardcover edition. “Orwell saw, to his credit, that the act of falsifying reality is only secondarily a way of changing perceptions. It is, above all, a way of asserting power.”—The New Yorker In 1984, London is a grim city in the totalitarian state of Oceania where Big Brother is always watching you and the Thought Police can practically read your mind. Winston Smith is a man in grave danger for the simple reason that his memory still functions. Drawn into a forbidden love affair, Winston finds the courage to join a secret revolutionary organization called The Brotherhood, dedicated to the destruction of the Party. Together with his beloved Julia, he hazards his life in a deadly match against the powers that be. Lionel Trilling said of Orwell’s masterpiece “1984 is a profound, terrifying, and wholly fascinating book. It is a fantasy of the political future, and like any such fantasy, serves its author as a magnifying device for an examination of the present.” Though the year 1984 now exists in the past, Orwell’s novel remains an urgent call for the individual willing to speak truth to power.
