With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    Told through an examination of animal and plant life today - with occasional juxtapositions of extinct fossil forms to reveal the origin of living creatures - "Life on Earth" is an astonishing pageant of life, with a cast of characters drawn from the whole range of living animals the world over. Attenborough's perceptive, dynamic approach to the evolution of some four million species of living organisms that populate the planet is to trace the most significant thread in the history of each major group. He then proceeds to explain from the evidence of living representatives and fossil remains why certain animals adapted and survived, evolved to more complex and "higher" forms of life, while others, by some inherent limitation imposed by their physiology or structure, failed and became extinct. "Life on Earth" is a book of wonders. A model of clarity and ease as a guide, Attenborough takes the reader around the world with him into jungles where orchids have petals that "impersonate" wasps to attract pollinating insects; to Australia, where honeypot ants force feed nectar to workers of a special caste, then hang them up by their forelegs like living storage jars; to remote mountains in Japan where little monkeys called macaques have learned to combat the winter snows by bathing in hot volcanic springs.

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    The answers will surprise and delight you as Alexandra Horowitz, a cognitive scientist, explains how dogs perceive their daily worlds, each other, and that other quirky animal, the human.Temple Grandin meets Stephen Pinker in this engaging and informative look at what goes on inside the minds of dogs—from a cognitive scientist with a background at The New Yorker.With more than 52 million pet dogs in America today, it’s clear we are a nation of unabashed dog-lovers. Yet the relationship between dogs and humans remains a fascinating mystery, as no one really knows what goes on in the canine mind. Now, in Inside of a Dog, Alexandra Horowitz fuses her perspectives as both scientist and dog-owner to deliver a fresh look at the world of dogs—as seen from the animal’s point of view. Inspired by her years of living with her own dog, Pumpernickel, who was a constant source of delight and mystery, Horowitz’s mind became filled with questions and ideas. In crisp, clear prose, she draws on her research in the field of dog cognition to give readers a sense of a dog’s perceptual and cognitive abilities—and paints a picture of what the canine experience is like. Horowitz’s own scientific journey, and the insights she uncovered, allowed her to understand her dog better and appreciate her more.Containing up-to-the minute research and providing many moments of dog-behavior recognition, this lively and absorbing book helps dog owners to see their best friend’s behavior in a different, and revealing light, allowing them to understand their pets and enjoy their company even more.

    If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible. In California, wildfires now rage year-round, destroying thousands of homes. Across the US, "500-year" storms pummel communities month after month, and floods displace tens of millions annually.This is only a preview of the changes to come. And they are coming fast. Without a revolution in how billions of humans conduct their lives, parts of the Earth could become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century.In his travelogue of our near future, David Wallace-Wells brings into stark relief the climate troubles that await--food shortages, refugee emergencies, and other crises that will reshape the globe. But the world will be remade by warming in more profound ways as well, transforming our politics, our culture, our relationship to technology, and our sense of history. It will be all-encompassing, shaping and distorting nearly every aspect of human life as it is lived today.Like An Inconvenient Truth and Silent Spring before it, The Uninhabitable Earth is both a meditation on the devastation we have brought upon ourselves and an impassioned call to action. For just as the world was brought to the brink of catastrophe within the span of a lifetime, the responsibility to avoid it now belongs to a single generation.

    A group of young scientists, under the guidance of Dr. George Church, the most brilliant geneticist of our time, works to make fantasy reality by sequencing the DNA of a frozen woolly mammoth harvested from above the Arctic circle, and splicing elements of that sequence into the DNA of a modern elephant. Will they be able to turn the hybrid cells into a functional embryo and bring the extinct creatures to life in our modern world?Along with Church and his team of Harvard scientists, a world-famous conservationist and a genius Russian scientist plan to turn a tract of the Siberian tundra into Pleistocene Park, populating the permafrost with ancient herbivores as a hedge against an environmental ticking time bomb.

    Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA.We learn that Neanderthal genes offer a unique window into the lives of our hominin relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Drawing on genetic and fossil clues, Pääbo explores what is known about the origin of modern humans and their relationship to the Neanderthals and describes the fierce debate surrounding the nature of the two species’ interactions. His findings have not only redrawn our family tree, but recast the fundamentals of human history—the biological beginnings of fully modern Homo sapiens, the direct ancestors of all people alive today.A riveting story about a visionary researcher and the nature of scientific inquiry, Neanderthal Man offers rich insight into the fundamental question of who we are.

    Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    Here is the Naked Ape at his most primal in love, at work, at war. Meet man as he really is: relative to the apes, stripped of his veneer as we see him courting, making love, sleeping, socializing, grooming, playing. The Naked Ape takes its place alongside Darwin’s Origin of the Species, presenting man not as a fallen angel, but as a risen ape, remarkable in his resilience, energy and imagination, yet an animal nonetheless, in danger of forgetting his origins. With its penetrating insights on man's beginnings, sex life, habits and our astonishing bonds to the animal kingdom, The Naked Ape is a landmark, at once provocative, compelling and timeless.

    In this gripping account, David Quammen takes the reader along on this astonishing quest to learn how, where from, and why these diseases emerge and asks the terrifying question: What might the next big one be?

    More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.Nothing like this has occurred in a generation--a raw exploration of new worlds unparalleled since NASA's Voyager missions to Uranus and Neptune--and nothing like it is planned to happen ever again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA's website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded but made history and captured the world's imagination.How did this happen? Chasing New Horizons is the story of the men and women behind the mission: of their decades-long commitment; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons' next encounter, 1 billion miles past Pluto. Told from the insider's perspective of Dr. Alan Stern--the man who led the mission--Chasing New Horizons is a riveting story of scientific discovery, and of how far humanity can go when people focused on a dream work together toward their incredible goal.

    There really are no ultimate authority figures-no one has the secret and there is no place to look up the definitive answers to our questions (not even Google). But, by thinking skeptically and logically, we can combat sloppy reasoning, bad arguments and superstitious thinking. It's difficult, and takes a lot of vigilance, but it's worth the effort.In this tie-in to their incredibly popular "The Skeptics Guide to the Universe" podcast, Steven Novella, MD along with "Skeptical Rogues" Bob Novella, Cara Santa Maria, Jay Novella, and Evan Bernstein will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies and conspiracy theories (Anti-vaccines, homeopathy, UFO sightings, etc.) They'll help us try to make sense of what seems like an increasingly crazy world using powerful tools like science and philosophy. THE SKEPTICS' GUIDE TO THE UNIVERSE is your guide through this maze of modern life. It covers essential critical thinking skills, as well as giving insight into how your brain works and how to avoid common pitfalls in thinking. They discuss the difference between science and pseudoscience, how to recognize common science news tropes, how to discuss conspiracy theories with that crazy coworker of yours, and how to apply all of this to everyday life.So, are you ready to join them on an epic scientific quest, one that has taken us from huddling in dark caves to stepping foot on the Moon? (Yes, we really did that.) Like all adventures, this one is foremost a journey of self discovery. The monsters you will slay and challenges you will face are mostly constructs of your own mind. With the SKEPTIC'S GUIDE TO THE UNIVERSE, we can do this together.

    To the right listener, they tell us all about themselves: where they came from, how they lived, how they died - and who killed them. Forensic scientists can unlock the mysteries of the past and help justice to be done using the messages left by a corpse, a crime scene or the faintest of human traces. Forensics uncovers the secrets of forensic medicine, drawing on interviews with top-level professionals, ground-breaking research and Val McDermid's own experience to lay bare the secrets of this fascinating science. And, along the way, she wonders at how maggots collected from a corpse can help determine time of death, how a DNA trace a millionth the size of a grain of salt can be used to convict a killer and how a team of young Argentine scientists led by a maverick American anthropologist uncovered the victims of a genocide.In her crime novels, Val McDermid has been solving complex crimes and confronting unimaginable evil for years. Now, she's looking at the people who do it for real, and real crime scenes. It's a journey that will take her to war zones, fire scenes and autopsy suites, and bring her into contact with extraordinary bravery and wickedness, as she traces the history of forensics from its earliest beginnings to the cutting-edge science of the modern day.
