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.

A daring new vision of quantum theory from one of the leading minds of contemporary physics. In Einstein's Unfinished Revolution, theoretical physicist Lee Smolin provocatively argues that the problems that have bedeviled quantum physics since its inception are unsolved and unsolvable, for the simple reason that the theory is incomplete.

Gazing at the stars, falling in love, or listening to music, we sometimes feel a transcendent connection with a cosmic unity and things larger than ourselves. But these experiences are not easily understood by science, which holds that all things can be explained in terms of atoms and molecules. Is there space in our scientific worldview for these spiritual experiences?

The intellectual adventure story of the "double-slit" experiment, showing how a sunbeam split into two paths first challenged our understanding of light and then the nature of reality itself - and continues to almost 200 years later. Through Two Doors at Once celebrates the elegant simplicity of an iconic experiment and its profound reach. With his extraordinarily gifted eloquence, Anil Ananthaswamy travels around the world, through history and down to the smallest scales of physical reality we have yet fathomed. It is the most fantastic voyage you can take.

With all the passion, curiosity, and precise yet lyrical prose that have marked his previous books, Alan Lightman here explores the emotional and philosophical questions raised by discoveries in science, focusing most intently on the human condition and the needs of humankind. He looks at the difficult dialogue between science and religion, the conflict between our human desire for permanence and the impermanence of nature, the possibility that our universe is simply an accident, the manner in which modern technology has separated us from direct experience of the world, and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution.

You make hundreds of decisions every day, from what to eat for breakfast to how you should invest, and not one of them could be made without the essential component of emotion. It has long been held that thinking and feeling are separate and opposing forces in our behavior. But as Leonard Mlodinow, the best-selling author of Subliminal, tells us, extraordinary advances in psychology and neuroscience have proven that emotions are as critical to our well-being as is rational thinking.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing 21st-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.

For at least 20,000 years, we have led not just an earthly existence, but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are - our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.

In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where, at the most fundamental level, time disappears.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This pause-resisting survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms.

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. 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 turn the tide in the fight against AIDS.

How do neurons turn into minds? The problem of consciousness has gnawed at us for millennia. In the last century there have been massive breakthroughs that have rewritten the science of the brain, and yet the puzzles faced by the ancient Greeks are still present. In The Consciousness Instinct, the neuroscience pioneer Michael S. Gazzaniga puts the latest research in conversation with the history of human thinking about the mind, giving a big-picture view of what science has revealed about consciousness.

The whole of Western natural philosophy is undergoing a sea change, forced upon us by the experimental findings of quantum theory. At the same time, these findings have increased our doubt and uncertainty about traditional physical explanations of the universe's genesis and structure. Biocentrism completes this shift in worldview, turning the planet upside down again with the revolutionary view that life creates the universe instead of the other way around.

In Beyond Biocentrism, acclaimed biologist Robert Lanza and astronomer Bob Berman take the listener on an intellectual thrill ride as they reexamine everything we thought we knew about life, death, the universe, and the nature of reality itself. The first step is acknowledging that our existing model of reality is looking increasingly creaky in the face of recent scientific discoveries.

Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal.

How much can we know about the world? In this audiobook physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing he reaches a provocative conclusion: Science, like religion, is fundamentally limited as a tool for understanding the world. As science and its philosophical interpretations advance, we face the unsettling recognition of how much we don't know.

Humans have long sought to comprehend the enormities of cosmic space and time. Here, best selling science writer Timothy Ferris tells the story of that quest. He interweaves the majestic themes of astronomy, physics, religion, and philosophy with fresh and lasting portraits of the men and women who created what has been called our society's most precious treasure - its conception of the universe at large.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

Blending biology, chemistry, and physics basics with accessible - and witty-prose, The Science of Rick and Morty equips you with the scientific foundation to thoroughly understand Rick's experiments from the show, such as how we can use dark matter and energy, just what is intelligence hacking, and whether or not you can really control a cockroach's nervous system with your tongue. Perfect for longtime and new fans of the show, this is the ultimate segue into discovering more about our complicated and fascinating universe.

Professor Brian Cox uncovers some of the most extraordinary natural events on Earth and in the universe and beyond. From the immensity of the universe and the roundness of Earth to the form of every single snowflake, the forces of nature shape everything we see. Pushed to extremes, the results are astonishing. In seeking to understand the everyday world, the colours, structure, behaviour and history of our home, we develop the knowledge and techniques necessary to step beyond the everyday.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy, and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.

A unique fusion of philosophy and metaphysics set against the backdrop of contemporary culture. Have you ever wondered if the world is really there when you're not looking? We tend to take the reality of our world very much for granted. This book will lead you down the rabbit hole in search of something we can point to, hang our hats on, and say this is real.

Shining a light on the most profound insights revealed by modern physics, Jim Al-Khalili invites us all to understand what this crucially important science tells us about the universe and the nature of reality itself. Al-Khalili begins by introducing the fundamental concepts of space, time, energy, and matter, and then describes the three pillars of modern physics - quantum theory, relativity, and thermodynamics - showing how all three must come together if we are ever to have a full understanding of reality.

The Big Bang is all but dead, and we do not yet know what will replace it. Our universe's "beginning" is at an end. What does this have to do with us here on Earth? Our lives are about to be dramatically shaken again - as altered as they were with the invention of the clock, the steam engine, the railroad, the radio and the Internet.

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. 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 turn the tide in the fight against AIDS.

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

Two of the boldest and most creative scientists of all time were Michael Faraday (1791-1867) and James Clerk Maxwell (1831-1879). This is the story of how these two men - separated in age by 40 years - discovered the existence of the electromagnetic field and devised a radically new theory which overturned the strictly mechanical view of the world that had prevailed since Newton's time.

With all the passion, curiosity, and precise yet lyrical prose that have marked his previous books, Alan Lightman here explores the emotional and philosophical questions raised by discoveries in science, focusing most intently on the human condition and the needs of humankind. He looks at the difficult dialogue between science and religion, the conflict between our human desire for permanence and the impermanence of nature, the possibility that our universe is simply an accident, the manner in which modern technology has separated us from direct experience of the world, and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.

A modern classic, Einstein's Dreams is a fictional collage of stories dreamed by Albert Einstein in 1905, when he worked in a patent office in Switzerland. As the defiant but sensitive young genius is creating his theory of relativity, a new conception of time, he imagines many possible worlds. In one, time is circular, and people are fated to repeat their triumphs and failures over and over. In another, there is a place where time stands still, visited by lovers and parents clinging to their children.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

Searching for Stars on an Island in Maine is the result of these seemingly contradictory impulses, written as an extended meditation on an island in Maine, where Lightman and his wife spend their summers. Framing the dialogue between religion and science as a contrast between absolutes and relatives, Lightman explores our human quest for truth and meaning and the different methods of religion and science in that quest. Along the way, he draws from sources ranging from St. Augustine's conception of absolute truth to Einstein's relativity.

Spanning millennia and continents, here is a stunningly revealing history of how the distribution of water has shaped human civilization. Giulio Boc­caletti - honorary research associate at the Smith School of Enterprise and the Environment, Univer­sity of Oxford - shrewdly combines environmental and social history, beginning with the earliest civ­ilizations of sedentary farmers on the banks of the Nile, the Tigris, and the Euphrates Rivers.

Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments.

In this timely and essential audiobook that offers a fresh take on the qualms of modern day life, Professor Alan Lightman investigates the creativity born from allowing our minds to freely roam, without attempting to accomplish anything and without any assigned tasks. With In Praise of Wasting Time, Professor Alan Lightman documents the rush and heave of the modern world, suggests the technological and cultural origins of our time-­driven lives, and examines the many values of "wasting time".

Until recently, microglia were thought to be merely the brain’s housekeepers, helpfully removing damaged cells. But a recent groundbreaking discovery revealed them to be capable of terrifying Jekyll and Hyde behavior. When triggered - and anything that stirs up the immune system in the body can activate microglia - they can morph into destroyers, impacting a wide range of issues from memory problems and anxiety to depression and Alzheimer’s. Under the right circumstances, however, microglia can be coaxed back into being angelic healers.
