We are now on the doorstep of a fourth change brought about by two technologies: AI and robotics. The Fourth Age provides extraordinary background information on how we got to this point, and how - rather than what - we should think about the topics we’ll soon all be facing: machine consciousness, automation, employment, creative computers, radical life extension, artificial life, AI ethics, the future of warfare, superintelligence, and the implications of extreme prosperity.

Sparked by a controversial debate in February 2014, Bill Nye has set off on an energetic campaign to spread awareness of evolution and the powerful way it shapes our lives. In Undeniable: Evolution and the Science of Creation, he explains why race does not really exist; evaluates the true promise and peril of genetically modified food; reveals how new species are born, in a dog kennel and in a London subway; takes a stroll through 4.5 billion years of time; and explores the new search for alien life, including aliens right here on Earth.

In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how subjective experience crept into being—how nature became aware of itself. As Godfrey-Smith stresses, it is a story that largely occurs in the ocean, where animals first appeared.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

For all of neuroscience's advances, we've made little progress on its biggest question: How do simple cells in the brain create intelligence? Jeff Hawkins and his team discovered that the brain uses map-like structures to build a model of the world - not just one model, but hundreds of thousands of models of everything we know. This discovery allows Hawkins to answer important questions about how we perceive the world, why we have a sense of self, and the origin of high-level thought.

In this provocative history of contemporary debates over evolution, veteran journalist Tom Bethell depicts Darwin's theory as a 19th-century idea past its prime, propped up by logical fallacies, bogus claims, and empirical evidence that is all but disintegrating under an onslaught of new scientific discoveries. Bethell presents a concise yet wide-ranging tour of the flash points of modern evolutionary theory. Bethell's account is enriched by his own personal encounters with of some of our era's leading scientists and thinkers.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

Perception is the foundation of human experience, but few of us understand why we see what we do, much less how. By revealing the startling truths about the brain and its perceptions, Beau Lotto shows that the next big innovation is not a new technology: It is a new way of seeing. In his first major book, Lotto draws on over two decades of pioneering research to explain that our brain didn't evolve to see the world accurately. It can't!

How to Be Animal tells a remarkable story of what it means to be human and argues that at the heart of our existence is a profound struggle with being animal. We possess a psychology that seeks separation between humanity and the rest of nature, and we have invented grand ideologies to magnify this. As well as piecing together the mystery of how this mindset evolved, Challenger's book examines the wide-reaching ways in which it affects our lives, from our politics to the way we distance ourselves from other species.

Laurence Gonzales turns his talent for gripping narrative, knowledge of the way our minds and bodies work, and bottomless curiosity about the world to the topic of how we can best use the lessons of our evolutionary history to overcome the hazards of everyday life. He finds that natural laws profoundly affect our actions, and he reveals the hidden causes and costs of our behavior, whether as individuals or as a species whose decisions may be leading to darker times.

One of the most powerful questions humans ask about the cosmos is: Are we alone? While the science behind this inquiry is fascinating, it doesn’t exist in a vacuum. It is a reflection of our values, our fears, and most importantly, our enduring sense of hope. In The Possibility of Life, acclaimed science journalist Jaime Green traces the history of our understanding, from the days of Galileo and Copernicus to our contemporary quest for exoplanets. Along the way, she interweaves insights from science fiction writers who construct worlds that in turn inspire scientists.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. But short of alien's landing in New York City, how do we know what they are like?

First coined by Richard Dawkins in The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation. Susan Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive-making tools, for example, or using language - survived and flourished, replicating themselves in as many minds as possible.

Why did the line of ancient humans who eventually evolved into us survive when the others were shown the evolutionary door? Chip Walter draws on new scientific discoveries to tell the fascinating tale of how our survival was linked to our ancestors being born more prematurely than others, having uniquely long and rich childhoods, evolving a new kind of mind that made us resourceful and emotionally complex; how our highly social nature increased our odds of survival; and why we became self aware in ways that no other animal seems to be.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 100 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

What is life? In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name; it is a domain where biology, computing, logic, chemistry, quantum physics, and nanotechnology intersect.

The American war in Vietnam has left many long-lasting scars that have not yet been sufficiently examined. The worst of them were inflicted in a tiny area bounded by the demilitarized zone between North and South and the Ho Chi Minh Trail in neighboring Laos. That small region saw the most intense aerial bombing campaign in history, the massive use of toxic chemicals, and the heaviest casualties on both sides.

Lynne Cox, internationally famous for swimming the world’s most difficult waterways without a wetsuit, and able to endure water temperatures so cold that it would kill anyone else, recognizes and celebrates all forms of athleticism in others, human or otherwise. And when she saw a video of a Newfoundland dog leaping from an airborne helicopter into Italian waters to save someone from drowning, Cox was transfixed by the rescue, and captivated by the magnificence, physicality, and daring of the dog.

The Indian subcontinent was the scene of dramatic upheavals a few thousand years ago. The Northwest region entered an arid phase, and erosion coupled with tectonic events played havoc with river courses. One of them disappeared. Celebrated as Sarasvati in the Rig Veda and the Mahabharata, this river was rediscovered in the early 19th century through topographic explorations by British officials. Recently, geological and climatological studies have probed its evolution and disappearance, while satellite imagery has traced the river's buried courses....

Iceland is home to only 330,000 people but more than 265 museums and public collections, ranging from the intensely physical, like the Icelandic Phallological Museum, which collects the penises of every mammal known to exist in Iceland, to the vaporously metaphysical, like the Museum of Icelandic Sorcery and Witchcraft, which poses a particularly Icelandic problem: how to display what can't be seen?

By the mid 1980s, AIDS hysteria was so rampant that a fearful and prejudiced public ignored stories of gay men falling ill with lesions and mouth ulcers. President Reagan avoided mentioning the disease entirely. Then, as chronicled in Blood Farm, a new HIV-positive population emerged, one that included kids like Ken Dixon, Brad Cross, and Ryan White who had been infected as young as ten years old. But how?

Born free in 1821 to two parents who had been enslaved, William Still was drawn to anti-slavery work from a young age. Hired as a clerk at the Anti-Slavery office in Philadelphia after teaching himself to read and write, he began directly assisting enslaved people who were crossing over from the South into freedom. Andrew Diemer captures the full range and accomplishments of Still’s life, from his resistance to Fugitive Slave Laws and his relationship with John Brown before the war, to his long career fighting for citizenship rights and desegregation until the early 20th century.

In the spring of 1964, Anchorage, Alaska, was a modern-day frontier town yearning to be a metropolis - the largest, proudest city in a state that was still brand-new. But just before sundown on Good Friday, the community was jolted by the most powerful earthquake in American history, a catastrophic 9.2 on the Richter Scale. This Is Chance! is the thrilling, cinematic story of a community shattered by disaster - and the extraordinary woman who helped pull it back together.

In a remote pocket of Nazi-held France, ordinary people risked their lives to rescue many hundreds of strangers, mostly Jewish children. Was this a fluke of history, or something more? Anthropologist Maggie Paxson, certainties shaken by years of studying strife, arrives on the Plateau to explore this phenomenon: What are the traits that make a group choose selflessness?

How did Los Angeles start the 20th century as a dusty frontier town and end up a century later as one of the globe's supercities - with unparalleled cultural, economic, and technological reach? In City at the Edge of Forever, Peter Lunenfeld constructs an urban portrait, layer by layer, from serendipitous affinities, historical anomalies, and uncanny correspondences.

Sita, the beloved princess of Mithila, is one of the most revered women in Indian history; so well known, yet probably the least understood. At every crossroad of her life, she chose acceptance and grace over self-pity. Her life was filled with sacrifice yet wherever she was, there was abundance. It was as if she was carved out of an intense longing for Rama, yet she had infinite patience.

Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones - from the tiniest particles to the nature of space-time itself - black holes might be the key to a deeper understanding of the cosmos.

From the oldest rocks, formed three billion years ago in Karnataka, to the arrival of our ancestors 50,000 years ago on the banks of the Indus, the author meticulously sifts through wide-ranging scientific disciplines and through the layers of earth to tell us the story of India, filled with a variety of fierce reptiles, fantastic dinosaurs, gargantuan mammals and amazing plants.
