Based on the abstract, general style of mathematical exposition favored by research mathematicians, its goal was to teach students not just to manipulate numbers and formulas, but to grasp the underlying mathematical concepts. The result, at least at first, was a great deal of confusion among teachers, students, and parents. Since then, the negative aspects of "new math" have been eliminated and its positive elements assimilated into classroom instruction.In this charming volume, a noted English mathematician uses humor and anecdote to illuminate the concepts underlying "new math": groups, sets, subsets, topology, Boolean algebra, and more. According to Professor Stewart, an understanding of these concepts offers the best route to grasping the true nature of mathematics, in particular the power, beauty, and utility of pure mathematics. No advanced mathematical background is needed (a smattering of algebra, geometry, and trigonometry is helpful) to follow the author's lucid and thought-provoking discussions of such topics as functions, symmetry, axiomatics, counting, topology, hyperspace, linear algebra, real analysis, probability, computers, applications of modern mathematics, and much more.By the time readers have finished this book, they'll have a much clearer grasp of how modern mathematicians look at figures, functions, and formulas and how a firm grasp of the ideas underlying "new math" leads toward a genuine comprehension of the nature of mathematics itself.

    Both are naive risk-takers. I loved this book!” —Temple Grandin, author of Animals Make Us Human and Animals in Translation A revelatory investigation of human and animal adolescence and young adulthood from the New York Times bestselling authors of Zoobiquity.With Wildhood, Harvard evolutionary biologist Barbara Natterson-Horowitz and award-winning science writer Kathryn Bowers have created an entirely new way of thinking about the crucial, vulnerable, and exhilarating phase of life between childhood and adulthood across the animal kingdom. In their critically acclaimed bestseller, Zoobiquity, the authors revealed the essential connection between human and animal health. In Wildhood, they turn the same eye-opening, species-spanning lens to adolescent young adult life. Traveling around the world and drawing from their latest research, they find that the same four universal challenges are faced by every adolescent human and animal on earth: how to be safe, how to navigate hierarchy; how to court potential mates; and how to feed oneself. Safety. Status. Sex. Self-reliance. How human and animal adolescents and young adults confront the challenges of wildhood shapes their adult destinies. Natterson-Horowitz and Bowers illuminate these core challenges through the lives of four animals in the wild: Ursula, a young king penguin; Shrink, a charismatic hyena; Salt, a matriarchal humpback whale; and Slavc, a roaming European wolf. Through their riveting stories—and those of countless others, from adventurous eagles and rambunctious high schooler to inexperienced orcas and naive young soldiers—readers get a vivid and game-changing portrait of adolescent young adults as a horizontal tribe, sharing behaviors and challenges, setbacks and triumphs. Upending our understanding of everything from risk-taking and anxiety to the origins of privilege and the nature of sexual coercion and consent, Wildhood is a profound and necessary guide to the perilous, thrilling, and universal journey to adulthood on planet earth.

    Gabrielle Walker, author, consultant to New Scientist and regular broadcaster with the BBC has written a book unlike any that has ever been written about the continent. Antarctica weaves all the significant threads into an intricate tapestry, made up of science, natural history, poetry, epic history, what it feels like to be there and why it draws so many different kinds of people back there again and again. It is only when all the parts come together that the underlying truths of the continent emerge. Antarctica is the most alien place on Earth, the only part of our planet where humans could never survive unaided. It is truly like walking on another planet. And yet, in its silence, its agelessness and its mysteries lie the secrets of our past, and of our future.

    Wolfram lets the world see his work in A New Kind of Science, a gorgeous, 1,280-page tome more than a decade in the making. With patience, insight, and self-confidence to spare, Wolfram outlines a fundamental new way of modeling complex systems. On the frontier of complexity science since he was a boy, Wolfram is a champion of cellular automata--256 "programs" governed by simple nonmathematical rules. He points out that even the most complex equations fail to accurately model biological systems, but the simplest cellular automata can produce results straight out of nature--tree branches, stream eddies, and leopard spots, for instance. The graphics in A New Kind of Science show striking resemblance to the patterns we see in nature every day. Wolfram wrote the book in a distinct style meant to make it easy to read, even for nontechies; a basic familiarity with logic is helpful but not essential. Readers will find themselves swept away by the elegant simplicity of Wolfram's ideas and the accidental artistry of the cellular automaton models. Whether or not Wolfram's revolution ultimately gives us the keys to the universe, his new science is absolutely awe-inspiring. --Therese Littleton

    Lopez’s classic, careful study has won praise from a wide range of reviewers and improved the way books on wild animals are written. Of Wolves and Men explores the uneasy interaction between wolves and civilization over the centuries, and the wolf's prominence in our thoughts about wild creatures. Drawing upon an impressive array of literature, history, science, and mythology as well as extensive personal experience with captive and free-ranging wolves, Lopez argues for the wolf's preservation and immerses the reader in its sensory world, creating a compelling portrait of the wolf both as a real animal and as imagined by different kinds of men. A scientist might perceive the wolf as defined by research data, while an Eskimo hunter sees a family provider much like himself. For many Native Americans the wolf is also a spiritual symbol, a respected animal that can strengthen the individual and the community. With irresistible charm and elegance, Of Wolves and Men celebrates careful scientific fieldwork, dispels folklore that has enabled the Western mind to demonize wolves, explains myths, and honors indigenous traditions, allowing us to understand how this remarkable animal has become so prominent for so long in the human heart.

    But that's not all -- food would be in much shorter supply, and available in much less variety. While the media focuses on colony-collapse disorder and the threats to honey bees specifically, the real danger is much greater: all bees are at risk. And because of the integral role these insects play in the ecology of our planet, we may be at risk as well.The life of Laurence Packer, a melittologist at Toronto's York University, revolves around bees, whether he's searching for them under leaves in a South American jungle or identifying new species in the desert heat of Arizona. Packer often finds himself in exotic and even dangerous locales, risking snake bites, sunstroke, and even the ire of other scientists. Everywhere he travels, he discovers the same unsettling trend: bees are disappearing. And since bees are responsible for up to one-third of our food supply, the consequences are frightening.

    Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives?male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon?s golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon?s Steed brings to life an aquatic treasure.Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon?s Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses? unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a ?keystone? species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.

    Although there are more than thirty thousand species of fish—more than all mammals, birds, reptiles, and amphibians combined—we rarely consider how individual fishes think, feel, and behave. Balcombe upends our assumptions about fishes, portraying them not as unfeeling, dead-eyed feeding machines but as sentient, aware, social, and even Machiavellian—in other words, much like us. What a Fish Knows draws on the latest science to present a fresh look at these remarkable creatures in all their breathtaking diversity and beauty. Fishes conduct elaborate courtship rituals and develop lifelong bonds with shoalmates. They also plan, hunt cooperatively, use tools, curry favor, deceive one another, and punish wrongdoers. We may imagine that fishes lead simple, fleeting lives—a mode of existence that boils down to a place on the food chain, rote spawning, and lots of aimless swimming. But, as Balcombe demonstrates, the truth is far richer and more complex, worthy of the grandest social novel. Highlighting breakthrough discoveries from fish enthusiasts and scientists around the world and pondering his own encounters with fishes, Balcombe examines the fascinating means by which fishes gain knowledge of the places they inhabit, from shallow tide pools to the deepest reaches of the ocean. Teeming with insights and exciting discoveries, What a Fish Knows offers a thoughtful appraisal of our relationships with fishes and inspires us to take a more enlightened view of the planet’s increasingly imperiled marine life. What a Fish Knows will forever change how we see our aquatic cousins—the pet goldfish included.
