What makes us moral beings? How do we decide what is good and what is evil? And has it always been that way? Hanno Sauer's sweeping new history of humanity, covering five million years of our universal moral values, comes at a crucial moment of crisis for those values, and helps to explain how they arose—and why we need them. Modern societies are in crisis: a shared universal morality seems to be a thing of the past. Hanno Sauer explains why this appearance is deceptive: in fact, there are universal values that all people share.

When he was six years old, Roger Penrose discovered a sundial in a clearing near his house. Through that machine made of light, shadow, and time, Roger glimpsed a “world behind the world” of transcendently beautiful geometry. It spurred him on a journey to become one of the world’s most influential mathematicians, philosophers, and physicists. Penrose would prove the limitations of general relativity, set a new agenda for theoretical physics, and astound colleagues and admirers with the elegance and beauty of his discoveries.

All of Earth’s oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes. Timely, elegant, and passionately argued, The Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet.

In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we?

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.

Why has war been such a consistent presence throughout the human past? A leading historian explains, drawing on rich examples and keen insight. Richard Overy is not the first scholar to take up the title question. In 1931, at the request of the League of Nations, Albert Einstein asked Sigmund Freud to collaborate on a short work examining whether there was "a way of delivering mankind from the menace of war." Published the next year as a pamphlet entitled Why War?, it conveyed Freud's conclusion that the "death drive" made any deliverance impossible.

Harriet Tubman is among the most famous Americans ever born and soon to be the face of the twenty-dollar bill. Yet often she’s a figure more out of myth than history, almost a comic-book superhero. You could almost say she’s America’s Robin Hood, a miraculous vision, often rightly celebrated but seldom understood. Tiya Miles’s extraordinary Night Flyer changes all that.

Something strange is going on in the cosmos. Scientists are uncovering a catalogue of weird phenomena that simply can’t be explained by our long-established theories of the universe. After decades of fruitless searching, could we finally be catching glimpses of a profound new view of our physical world? Or are we being fooled by cruel tricks of the data? In Space Oddities, Harry Cliff, a physicist who does cutting-edge work on the Large Hadron Collider, provides a riveting look at the universe’s most confounding puzzles.

Bestselling historian and Pulitzer Prize finalist H. W. Brands narrates the fierce debate over America's role in the world in the runup to World War II through its two most important figures: President Franklin D. Roosevelt, who advocated intervention, and his isolationist nemesis, aviator and popular hero Charles Lindbergh.

We’ve all heard the phrase “it’s not brain surgery.” But what exactly is brain surgery? It’s a profession that is barely a hundred years old and profoundly connects two human beings, but few know how it works, or its history. In this warm, rigorous, and deeply insightful book, Dr. Theodore H. Schwartz explores what it’s like to hold the scalpel, wield the drill, extract a tumor, fix a bullet hole, and remove a blood clot—when every second can mean life or death.

This small book indeed tells a big story. It is the story of capitalism–of how our market system developed. It is the story of the discipline of economics, and some of the key figures who formed it. And it is the story of how economic forces have shaped world history. Why didn’t Africa colonize Europe instead of the other way around? What happened when countries erected trade and immigration barriers in the 1930s? Why did the Allies win World War II? You’ll find answers to these questions and more in How Economics Explains the World.

In this illuminating overview, Professor Garrett Thomson surveys the field, considering the work and influence of 29 major thinkers representing logical atomism and logical positivism (including Russell and Wittgenstein), analytic philosophy (including Quine, Davidson, Rawls), phenomenology and existentialism (including Husserl, Heidegger, Sartre), hermeneutics (including Gadamer and Habermas) and post-structuralism (including Foucault, Derrida and Deleuze). Also examined are some recent thinkers including Richard Rorty and Charles Taylor.

Have you ever wondered what makes dough rise? Or how your morning coffee gives you that energy boost? Or why your shampoo is making your hair look greasy? The answer is chemistry. From the moment we wake up until the time we go to sleep (and even while we sleep), chemistry is at work - and it doesn't take a PhD in science to understand it.

Over thousands of years, the Mississippi watershed was home to millions of Indigenous people who regarded "the great river" with awe and respect, adorning its banks with astonishing spiritual earthworks. But European settlers and American pioneers had a different vision: the river was a foe to conquer. In this landmark work of natural history, Boyce Upholt tells the epic story of human attempts to own and contain the Mississippi River, from Thomas Jefferson's expansionist land hunger through today's era of environmental concern

Books about the origins of humanity dominate bestseller lists, while national newspapers present breathless accounts of new archaeological findings and speculate about what those findings tell us about our earliest ancestors. We are obsessed with prehistory—and, in this respect, our current era is no different from any other in the last three hundred years. In this coruscating work, acclaimed historian Stefanos Geroulanos demonstrates how claims about the earliest humans not only shaped Western intellectual culture, but gave rise to our modern world.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.

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.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

The world today is undergoing the most rapid environmental transformation in human history—from climate change to deforestation. Scientists, ethnobotanists, indigenous peoples, and collectives of all kinds are closely studying trees and their biology to understand how and why trees function individually and collectively in the ways they do. In Twelve Trees, Daniel Lewis, curator and historian at one of the world’s most renowned research libraries, travels the world to learn about these trees in their habitats.

In the eighteenth century, two men—exact contemporaries and polar opposites—dedicated their lives to the same daunting task: identifying and describing all life on Earth. Carl Linnaeus, a pious Swedish doctor with a huckster’s flair, believed that life belonged in tidy, static categories. Georges-Louis de Buffon, an aristocratic polymath and keeper of France’s royal garden, viewed life as a dynamic swirl of complexities. Each began his task believing it to be difficult but not impossible: How could the planet possibly hold more than a few thousand species—or as many could fit on Noah’s Ark?

In the summer of 1941, German troops surrounded the Russian city of Leningrad—now St. Petersburg—and began the longest blockade in recorded history, one that would ultimately claim the lives of nearly three-quarters of a million people. At the center of the besieged city stood a converted palace that housed the world’s largest collection of seeds—more than 250,000 samples hand-collected over two decades from all over the globe by world-famous explorer, geneticist, and dissident Nikolai Vavilov, who had recently been disappeared by the Soviet government.

Written in taut, urgent prose, Hum is a work of speculative fiction that unflinchingly explores marriage, motherhood, and selfhood in a world compromised by global warming and dizzying technological advancement, a world of both dystopian and utopian possibilities.

A gripping journey of discovery, The Catalyst moves from the early experiments that first hinted at RNA's spectacular powers, to Cech's own paradigm-shifting finding that it can catalyze cellular reactions, to the cutting-edge biotechnologies poised to reshape our health.

Drawing on the latest scholarship as well as eyewitness reports, diary entries, and memoirs, Lloyd moves from the great battles of 1914 to the final collapse of the Central Powers in 1918, showing how a local struggle between Austria-Hungary and Serbia spiraled into a massive conflagration that pulled in Germany, Russia, Italy, Romania, and Bulgaria.

In How the World Made the West, Josephine Quinn poses perhaps the most significant challenge ever to the “civilizational thinking” regarding the origins of Western culture—that is, the idea that civilizations arose separately and distinctly from one another. Rather, she locates the roots of the modern West in everything from the law codes of Babylon, Assyrian irrigation, and the Phoenician art of sail to Indian literature, Arabic scholarship, and the metalworking riders of the Steppe, to name just a few examples.

When Amitav Ghosh began the research for his monumental cycle of novels the Ibis trilogy ten years ago, he was startled to learn how the lives of the nineteenth-century sailors and soldiers he wrote about were dictated not only by the currents of the Indian Ocean but also by the precious commodity carried in enormous quantities on those currents: opium. Most surprising of all, however, was the discovery that his own identity and family history were swept up in the story. Smoke and Ashes is at once a travelogue, a memoir, and an essay in history, drawing on decades of archival research.

A leading national security expert, who publicly predicted Vladimir Putin's intention to launch a full-scale invasion of Ukraine months before it took place, lays out the case for why China's Xi Jinping is preparing to conquer Taiwan in the coming years and the dire stakes for America and the whole world if he is not deterred.

Acclaimed presidential historian Tevi Troy takes listeners on a riveting journey through the biggest battles between CEOs and the nation’s commander in chief. He unearths the untold stories—both political and personal—that have shaped America. The Power and the Money shows how some of the nation’s most important CEOs forged (and fumbled) relationships with the president, revealing an intricate web of power, where CEOs need presidents, and presidents need CEOs. Troy shows how each must step carefully—or risk unpredictable costs and collateral damage.

No animal is so entangled in human history as the horse. The thread starts in prehistory, with a slight, shy animal, hunted for food. Domesticating the horse allowed early humans to settle the vast Eurasian steppe; later, their horses enabled new forms of warfare, encouraged long-distance trade routes, and ended up acquiring deep cultural and religious significance.

Impossible Monsters reveals the central role of dinosaurs and their discovery in toppling traditional religious authority, and in changing perceptions about the Bible, history, and mankind's place in the world.
