Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing? Krauss’ answers to these and other timeless questions, in a wildly popular lecture on YouTube, has attracted almost a million viewers. One of the few prominent scientists to have actively crossed the chasm between science and popular culture, Krauss reveals that modern science is indeed addressing the question of why there is something rather than nothing—with surprising and fascinating results.

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.

The conditions that allowed humans to live on this earth are fragile, incredibly so. Climate variability has at times created new niches that humans or their ancestors could potentially exploit, and challenges that at times have spurred innovation. But there’s a relatively narrow envelope of climate variability within which human civilization remains viable. And our survival depends on conditions remaining within that range. In this book, renowned climate scientist Michael Mann will arm listeners with the knowledge necessary to appreciate the gravity of the unfolding climate crisis.

We understand the stars at a much deeper level, not as legendary figures connected with constellations, but as engines of matter, energy, and the raw material of life itself. The Life and Death of Stars introduces you to this story in 24 half-hour lectures that lead you through the essential ideas of astrophysics - the science of stars. Your guide is Professor Stassun, an award-winning teacher and noted astrophysicist. He provides lively, eloquent, and authoritative explanations at a level suitable for science novices as well as for those who already know their way around the starry sky.

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the southeast United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea.

In November 1987, a young couple on an overnight trip to Seattle vanished without a trace. A week later, the bodies of Tanya Van Cuylenborg and her boyfriend Jay Cook were found in rural Washington. It was a brutal crime, and it was the perfect crime: With few clues and no witnesses, an international manhunt turned up empty, and the sensational case that shocked the Pacific Northwest gradually slipped from the headlines.

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.

Under the aegis of machine learning in our data-driven machine age, computers are programming themselves and learning about - and solving - an extraordinary range of problems, from the mundane to the most daunting. Today it is machine learning programs that enable Amazon and Netflix to predict what users will like, Apple to power Siri's ability to understand voices, and Google to pilot cars.

With this updated edition of his earlier book, A Place of My Own, listeners can revisit the inspired, intelligent, and often hilarious story of Pollan’s realization of a room of his own—a small, wooden hut, his “shelter for daydreams” — built with his admittedly unhandy hands. Inspired by both Thoreau and Mr. Blandings, A Place of My Own not only works to convey the history and meaning of all human building, it also marks the connections between our bodies, our minds, and the natural world.

Perhaps the greatest physicist of the second half of the 20th century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits.

Bears have always held a central place in our collective memory, from Indigenous folklore and Greek mythology to nineteenth-century fairytales and the modern toy shop. But as humans and bears come into ever-closer contact, our relationship nears a tipping point. Today, most of the eight remaining bear species are threatened with extinction. Some, such as the panda bear and the polar bear, are icons of the natural world; others, such as the spectacled bear and the sloth bear, are far less known.

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work.

We live in a gendered world, where we are ceaselessly bombarded by messages about sex and gender. On a daily basis, we face deeply ingrained beliefs that sex determines our skills and preferences, from toys and colors to career choice and salaries. But what does this constant gendering mean for our thoughts, decisions, and behavior? And what does it mean for our brains? Drawing on her work as a professor of cognitive neuroimaging, Gina Rippon unpacks the stereotypes that surround us from our earliest moments and shows how these messages mold our ideas of ourselves.

Now settled into the sleepy Yorkshire village of Darrowby, and married to Helen the farmer’s daughter, James Herriot thinks he’s finally got himself sorted. But life as a vet in the 1930s was never going to be easy. Quite aside from his unpredictable colleagues, brothers Siegfried and Tristan Farnon, he must contend with new-fangled medical techniques, delivering calves after far too much homemade wine, and a grudge-holding dog called Magnus who never forgets.

Politicians, pseudo-experts, and other partisans have led us to believe that there are only two approaches to climate change: doomerism or denial. Benji Backer, Founder and Executive Chairman of the American Conservation Coalition, argues that both are dead ends. In The Conservative Environmentalist, he delivers an entirely new strategy to take care of the planet while putting the economic interest of the American people first.

In 12 fiercely funny, mind-expanding chapters, Dawkins explains how the natural world arose without a designer - the improbability and beauty of the "bottom-up programming" that engineers an embryo or a flock of starlings - and challenges head-on some of the most basic assumptions made by the world’s religions: Do you believe in God? Which one? Is the Bible a "Good Book"? Is adhering to a religion necessary, or even likely, to make people good to one another? Outgrowing God is a concise, provocative guide to thinking for yourself.

The incredible true story of the entrepreneur turned conservationist - the founder of the iconic company The North Face who used his fortune to protect more than 25 million acres of land from development and exploitation and “foster peace between people and wild nature”.

Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to ​harbor life.
