“If you liked Chaos, you’ll love Complexity. Waldrop creates the most exciting intellectual adventure story of the year” (The Washington Post). In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell—and what the origin of life some four billion years ago can tell us about the process of technological innovation today. This book is their story—the story of how they have tried to forge what they like to call the science of the twenty-first century. “Lucidly shows physicists, biologists, computer scientists and economists swapping metaphors and reveling in the sense that epochal discoveries are just around the corner . . . [Waldrop] has a special talent for relaying the exhilaration of moments of intellectual insight.” —The New York Times Book Review “Where I enjoyed the book was when it dove into the actual question of complexity, talking about complex systems in economics, biology, genetics, computer modeling, and so on. Snippets of rare beauty here and there almost took your breath away.” —Medium “[Waldrop] provides a good grounding of what may indeed be the first flowering of a new science.” —Publishers Weekly

Presents over 125 games, including picture puzzles, scrambled comics, riddle searches, logic defiers, memory contests, connect-the-dots, out-of-orders, mazes, crisscrosses, and rebuses.

PULITZER PRIZE WINNER • A “vivid and devastating” (The New York Times) portrait of an indomitable girl—from acclaimed journalist Andrea Elliott “From its first indelible pages to its rich and startling conclusion, Invisible Child had me, by turns, stricken, inspired, outraged, illuminated, in tears, and hungering for reimmersion in its Dickensian depths.”—Ayad Akhtar, author of Homeland Elegies ONE OF THE TEN BEST BOOKS OF THE YEAR: The New York Times • ONE OF THE BEST BOOKS OF THE YEAR: The Atlantic, The New York Times Book Review, Time, NPR, Library Journal In Invisible Child, Pulitzer Prize winner Andrea Elliott follows eight dramatic years in the life of Dasani, a girl whose imagination is as soaring as the skyscrapers near her Brooklyn shelter. In this sweeping narrative, Elliott weaves the story of Dasani’s childhood with the history of her ancestors, tracing their passage from slavery to the Great Migration north. As Dasani comes of age, New York City’s homeless crisis has exploded, deepening the chasm between rich and poor. She must guide her siblings through a world riddled by hunger, violence, racism, drug addiction, and the threat of foster care. Out on the street, Dasani becomes a fierce fighter “to protect those who I love.” When she finally escapes city life to enroll in a boarding school, she faces an impossible question: What if leaving poverty means abandoning your family, and yourself? A work of luminous and riveting prose, Elliott’s Invisible Child reads like a page-turning novel. It is an astonishing story about the power of resilience, the importance of family and the cost of inequality—told through the crucible of one remarkable girl. Winner of the J. Anthony Lukas Book Prize • Finalist for the Bernstein Award and the PEN/John Kenneth Galbraith Award
