When Newton discovered the law of gravity, he unified the rules governing the heavens and the Earth. Since then, physicists have been placing new forces into ever-grander theories. But perhaps the ultimate challenge is achieving a monumental synthesis of the two remaining theories—relativity and the quantum theory. This would be the crowning achievement of science, a profound merging of all the forces of nature into one beautiful, magnificent equation to unlock the deepest mysteries in science: What happened before the Big Bang?

As the country's top forensic pathologist, Dr Richard Shepherd has spent a lifetime uncovering the secrets of the dead. When death is sudden or unexplained, it falls to Shepherd to establish the cause. Each post-mortem is a detective story in its own right - and Shepherd has performed over 23,000 of them. Through his skill, dedication and insight, Dr Shepherd solves the puzzle to answer our most pressing question: how did this person die?

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.

Denial presents a radical new theory on the origins of our species. It was not, the authors argue, a biological leap that set humanity apart from other species, but a psychological one: namely, the uniquely human ability to deny reality in the face of inarguable evidence - including the willful ignorance of our own inevitable deaths.

Posez une question, Bryson y répond dans ce livre, clair, synthétique, vivant, truffé d'anecdotes, qui conjugue avec bonheur science et sourire. Vous y apprendrez sans efforts par quels hasards, traits de génie, intuitions, déductions, expérimentations, débats, les hommes en sont arrivés à connaître le monde tel qu'ils le connaissent aujourd'hui.

Unsettling Canada, a Canadian best seller, is built on a unique collaboration between two First Nations leaders, Arthur Manuel and Grand Chief Ron Derrickson.Both men have served as chiefs of their bands in the B.C. interior and both have gone on to establish important national and international reputations. But the differences between them are in many ways even more interesting. Arthur Manuel is one of the most forceful advocates for Aboriginal title and rights in Canada and comes from the activist wing of the movement.

Join lauded marine biologist Dr. Sarika Cullis-Suzuki for an intimate tour of the wild heart of the nation. From the Tombstone Mountains of the Yukon Territory to the glowing grasslands of Saskatchewan, each episode is alive with the buzzes, warbles, and howls of Canadian wildlife. Cullis-Suzuki is your guide, painting a picture of the landscapes around you while letting you in on the wilderness stories unfolding.

More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans.

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.

In April 1982, ethnobotanist Wade Davis arrived in Haiti to investigate two documented cases of zombies - people who had reappeared in Haitian society years after they had been officially declared dead and had been buried. Drawn into a netherworld of rituals and celebrations, Davis penetrated the vodoun mystique deeply enough to place zombification in its proper context within vodoun culture. In the course of his investigation, Davis came to realize that the story of vodoun is the history of Haiti.

The idea that “thoughts become things” has become a meme in popular culture. It’s held as a firm proposition in metaphysics, and some spiritual teachers ascribe infinite powers to the mind. But are these claims scientifically accurate? What does the scientific evidence tell us about the scope of the human mind to transform thoughts into reality?

This is an audiobook about math, but it contains no numbers. Math Without Numbers is a vivid, conversational, and wholly original guide to the three main branches of abstract math - topology, analysis, and algebra - which turn out to be surprisingly easy to grasp. This audiobook upends the conventional approach to math, inviting you to think creatively about shape and dimension, the infinite and infinitesimal, symmetries, proofs, and how these concepts all fit together. Join this freewheeling tour of the inimitable joys and unsolved mysteries of this curiously powerful subject.

The world is never finished catching up with Vaclav Smil. In his latest and perhaps most digestible book, Invention and Innovation, the prolific author—a favorite of Bill Gates—pens an insightful and fact-filled jaunt through the history of human invention. Impatient with the hype that so often accompanies innovation, Smil offers in this book a clear-eyed corrective to the overpromises that accompany everything from new cures for diseases to AI.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

Groundbreaking anthropologist and memory champion Lynne Kelly reveals how we can use ancient and traditional mnemonic methods to enhance and expand our memory.

The Log from the Sea of Cortez is the exciting day-by-day account of Steinbeck's trip to the Gulf of California with biologist Ed Ricketts. Drawn from the longer Sea of Cortez, it is a wonderful combination of science, philosophy, and high-spirited adventure.

Here is the epic history of the "iron men in wooden boats" who built an industrial empire through the pursuit of whales. This absorbing history demonstrates that few things can capture the sheer danger and desperation of men on the deep sea as dramatically as whaling. This sweeping social and economic history provides rich and often fantastic accounts of the men themselves, who mutinied, murdered, rioted, deserted, drank, scrimshawed, and recorded their experiences in journals and memoirs.

The science on climate change has been clear for a very long time now. Yet despite decades of appeals, mass street protests, petition campaigns, and peaceful demonstrations, we are still facing a booming fossil fuel industry, rising seas, rising emission levels, and a rising temperature. With the stakes so high, why haven't we moved beyond peaceful protest? In this lyrical manifesto, noted climate scholar (and saboteur of SUV tires and coal mines) Andreas Malm makes an impassioned call for the climate movement to escalate its tactics in the face of ecological collapse.

For centuries, poets and philosophers extolled the benefits of a walk in the woods: Beethoven drew inspiration from rocks and trees; Wordsworth composed while tromping over the heath; Nikola Tesla conceived the electric motor while visiting a park. Intrigued by our storied renewal in the natural world, Florence Williams sets out to uncover the science behind nature's positive effects on the brain.
