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.

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.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.

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.

From launchpad explosions to a pernicious cricket infestation to the demanding management style of Musk himself, the rise of SpaceX was beset with challenges and far from inevitable. Find out how the startup beat the odds and flew high enough to outpace their rivals... and where they're going next.

How do today's most successful tech companies - Amazon, Google, Facebook, Netflix, Tesla - design, develop, and deploy the products that have earned the love of literally billions of people around the world? Perhaps surprisingly, they do it very differently from the vast majority of tech companies. In Inspired, technology product management thought leader Marty Cagan provides listeners with a master class in how to structure and staff a vibrant and successful product organization and how to discover and deliver technology products that your customers will love.

In The Butchering Art, the historian Lindsey Fitzharris reveals the shocking world of 19th-century surgery on the eve of profound transformation. She conjures up early operating theaters - no place for the squeamish - and surgeons, working before anesthesia, who were lauded for their speed and brute strength. They were baffled by the persistent infections that kept mortality rates stubbornly high. A young, melancholy Quaker surgeon named Joseph Lister would solve the deadly riddle and change the course of history.

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

Drawing together many histories - of anatomical evolution and city design, of treadmills and labyrinths, of walking clubs and sexual mores - Rebecca Solnit creates a fascinating portrait of the range of possibilities presented by walking. Arguing that the history of walking includes walking for pleasure as well as for political, aesthetic, and social meaning, Solnit focuses on the walkers whose everyday and extreme acts have shaped our culture, from philosophers to poets to mountaineers.

Over the span of two hundred years, Great Britain established, governed, lost, and reconstructed an empire that embraced three continents and two oceanic worlds. The British ruled this empire by correlating incoming information about the conduct of subjects and aliens in imperial spaces with norms of good governance developed in London. Officials derived these norms by studying the histories of government contained in the official records of both the state and corporations and located in repositories known as archives.

Gases are all around us—they fill our lungs, power our movement, create stars, and warm our atmosphere. Often invisible and sometimes odorless, these ubiquitous substances are also the least understood materials in our world, and always have been. It wasn’t long ago that gases were seen as the work of ancient spirits: the sudden closing of a door after a change in airflow signaled a ghost’s presence.

Music is one of humanity’s oldest medicines. From the Far East to the Ottoman Empire, Europe to Africa and the pre-colonial Americas, many cultures have developed their own rich traditions for using sound and rhythm to ease suffering, promote healing, and calm the mind. In his latest work, neuroscientist and New York Times best-selling author Daniel J. Levitin (This Is Your Brain on Music) explores the curative powers of music, showing us how and why it is one of the most potent therapies today.

Carrot Quinn fears that she's become addicted to the Internet. The city makes her numb, and she's having trouble connecting with others. In a desperate move, she breaks away from everything to walk 2,660 miles from Mexico to Canada on the Pacific Crest Trail. It will be her first long-distance hike.

The Appalachian Trail trail stretches from Georgia to Maine and covers some of the most breathtaking terrain in America - majestic mountains, silent forests, sparking lakes. If you’re going to take a hike, it’s probably the place to go. And Bill Bryson is surely the most entertaing guide you’ll find. He introduces us to the history and ecology of the trail and to some of the other hardy (or just foolhardy) folks he meets along the way - and a couple of bears. Already a classic, A Walk in the Woods will make you long for the great outdoors (or at least a comfortable chair to sit and read in).

If the history of the Earth were compressed down to a year, our species would arise in the last thirty minutes or so of the final hour. But life itself is not such a late arrival: It has existed on Earth for something like 3.7 billion years—most of our planet’s history and over a quarter of the age of the universe (as far as we can tell). What have these organisms—bacteria, animals, plants, and the rest—done in all this time? In Living on Earth, the philosopher Peter Godfrey-Smith proposes a new way of understanding how the actions of living beings have shaped our planet.

What does it take to raise a great dog? This was the question that husband-and-wife team Brian Hare and Vanessa Woods hoped to answer when they enrolled one hundred and one puppies in the Duke Puppy Kindergarten. With the help of a retired service dog named Congo, Brian, Vanessa, and their team set out to understand the secrets of the puppy mind: What factors might predict whether a puppy will grow up to change someone’s life?

For years, one group of Americans has worked as foot-soldiers for the most authoritarian regimes around the planet. In the process, they've not only entrenched dictatorships and spread kleptocratic networks, but they've secretly guided U.S. policy without the rest of America even being aware. And now, some of them have begun turning their sights on American democracy itself. These Americans are known as foreign lobbyists, and many of them spent years ushering dictatorships directly into the halls of Washington, all while laundering the reputations of the most heinous regimes in the process.

We are living in a golden age in astronomy and in the search for life the universe. Over the last few decades, space exploration has shown that not only are there habitable environments within our solar system, but there are millions of exoplanets within our galaxy that could support life. We are on the cusp of breakthroughs that will revolutionize our understanding of our place in the cosmos in. In The Secret Life of the Universe, astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie A. Cabrol takes us to the frontiers of the search for life.
