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.

We tend to think of the Middle Ages as a dark, backward, and unchanging time characterized by violence, ignorance, and superstition. By contrast, we believe progress arose from science and technological innovation, and that inventions of recent centuries created the modern world. We couldn't be more wrong.

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.

In this “monumental and impressive” biography, Max Boot, the distinguished political columnist, illuminates the untold story of Ronald Reagan, revealing the man behind the mythology.

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.

Celebrated storyteller and historian Edward Dolnick leads us through a compelling true adventure as the paleontologists of the first half of the 19th century puzzled their way through the fossil record to create the story of dinosaurs we know today. The tale begins with Mary Anning, a poor, uneducated woman who had a sixth sense for finding fossils buried deep inside cliffs; and moves to a brilliant, eccentric geologist named William Buckland.

For all the attempts to understand the state of American politics and the blue/red divide, we've ignored what economic and cultural loss can do to pride. What happens, Arlie Russell Hochschild asks, when a proud people in a hard-hit region suffer the deep loss of pride and are confronted with a powerful political appeal that makes it feel "stolen"? Hochschild's research drew her to Pikeville, Kentucky, in the heart of Appalachia, within the whitest and second-poorest congressional district in the nation.

Slimak has travelled around the world for the past thirty years to uncover who the Neanderthals really were. A modern-day Indiana Jones, he takes us on a fascinating archaeological investigation: from the Arctic Circle to the deep Mediterranean forests, he traces the steps of these enigmatic creatures, working to decipher their real stories through every single detail they left behind.

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.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

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.

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 this engaging, accessible account, Nadine Akkerman and Pete Langman explore the methods spies actually used in the period, including disguises, invisible inks, and even poisons. Drawing on a vast array of archival sources, they show how understanding the tricks and tools of espionage allows us to reimagine well-known stories such as the Babington and Gunpowder plots.

This audiobook narrated by acclaimed archaeologist and best-selling author Eric Cline offers a breathtaking account of how the collapse of an ancient civilized world ushered in the first Dark Ages.

In an alternative 2011, the Mental Parity movement takes hold. Americans now embrace the sacred, universal truth that there is no such thing as variable human intelligence. Because everyone is equally smart, discrimination against purportedly dumb people is ""the last great civil rights fight."" Tests, grades, and employment qualifications are all discarded. Children are expelled for saying the S-word (“stupid”) and encouraged to report parents who use it at home.

Celebrated storyteller and historian Edward Dolnick leads us through a compelling true adventure as the paleontologists of the first half of the 19th century puzzled their way through the fossil record to create the story of dinosaurs we know today. The tale begins with Mary Anning, a poor, uneducated woman who had a sixth sense for finding fossils buried deep inside cliffs; and moves to a brilliant, eccentric geologist named William Buckland.

Our world has ended five times: It has been broiled, frozen, poison gassed, smothered, and pelted by asteroids. In The Ends of the World, Peter Brannen dives into deep time, exploring Earth's past dead ends, and in the process offers us a glimpse of our possible future. Many scientists now believe that the climate shifts of the 21st century have analogs in these five extinctions.

The Clockwork Universe is the story of a band of men who lived in a world of dirt and disease but pictured a universe that ran like a perfect machine. A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with natures most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.

Dinosaurs. No other class of animals captures the hearts of both children and adults alike. Paleontologist Armin Schmitt brings us a firsthand account of the latest research on dinosaurs and their lives millions of years ago, including his spectacular global excavations and fascinating discoveries in the field. With the help of cutting-edge technology and unbelievable new finds, the age-old tale of the dinosaurs is now revitalized for the very first time, complete with astonishing illustrations by Ben Rennen that help us imagine dinosaurs like never before.

In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs' lives from their fossils - their colors, their growth, and even whether we will ever be able to bring them back to life.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.

In 1945, post-fascist Italy was devastated by war, and its reputation in the international arena was nil. Yet by December 1955, when Italy was admitted to the United Nations, the nation had contested three acrimonious but free general elections, had a flourishing press, and was a leader in the rebuilding of Europe.

We feel, therefore we are. Conscious sensations ground our sense of self. They are crucial to our idea of ourselves as psychic beings: present, existent, and mattering. But is it only humans who feel this way? Do other animals? Will future machines? Weaving together intellectual adventure and cutting-edge science, Nicholas Humphrey describes in Sentience his quest for answers: from his discovery of blindsight in monkeys and his pioneering work on social intelligence to breakthroughs in the philosophy of mind.
