The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

The Yukon river is over 2,000 miles long, flowing northwest from Canada through the Yukon Territory and Alaska to the Bering Sea. Every summer, hundreds of thousands of king salmon migrate the distance of this river to their spawning grounds, where they breed and die in what is the longest salmon run in the world. For the communities that live along the Yukon, the fish have long been the lifeblood of the economy and local culture.

From facial recognition—capable of checking us onto flights or identifying undocumented residents—to automated decision systems that inform everything from who gets loans to who receives bail, each of us moves through a world determined by data-empowered algorithms. But these technologies didn't just appear: they are part of a history that goes back centuries, from the census enshrined in the US Constitution to the birth of eugenics in Victorian Britain to the development of Google search.

In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel-driven civilization and offers listeners a magisterial overview of humanity's energy eras.

Consider these commonly held scientific beliefs: Planetary orbits are fixed ellipses; we only use 10 percent of our brains; nothing travels faster than light; a thrown object’s trajectory is a parabola. They seem correct, but they’re all misconceptions that aren’t entirely accurate. There’s much more to the story than you think. These magnificent 24 lectures are devoted to busting myths, clearing up confusion, and giving you scientific epiphanies that could change how you think about your everyday world.

This original audiobook considers one of the most extraordinary scientific and political stories of our time: how in the 1980s a handful of scientists came to believe that mankind faced catastrophe from runaway global warming, and how today this has persuaded politicians to land us with what promises to be the biggest bill in history. Christopher Booker interweaves the science of global warming with that of its growing political consequences, showing how just when the politicians are threatening to change our Western way of life beyond recognition, the scientific evidence behind the global warming theory is being challenged like never before.

This gripping true story follows a biologist's human-powered journey from the Pacific Northwest to the Arctic to rediscover her love of birds, nature, and adventure—perfect for fans of Cheryl Strayed.​

Around the World in 80 Games is about the mathematics of chance, game theory, gamification, gaming strategies and computer games. Traversing the globe, Marcus du Sautoy looks at the genesis of games new and old, explores how to invent a good game and explains the fascination of a popular lockdown game. The most simple games endure: board games, card games and dice games have captivated us for centuries and the acclaimed mathematician and author of The Creativity Code (among many others) will once again bring mathematics to the fore with insight and aplomb in Around the World in 80 Games.

Many horse trainers, even those who espouse the so-called natural horsemanship approach, take the position that horses who fail to obey a human's request are doing so as much out of perversity as ignorance. That's not Mark Rashid's view. In his words, "If we understand that horses can't separate the way they feel from the way they act, then we can start to see that unwanted behavior isn't bad behavior at all. More times than not, it's just the horse expressing the way he feels at that particular moment in time....

The Great Simplification with Nate Hagens explores money, energy, economy, and the environment with world experts and leaders to understand how everything fits together, and where we go from here.

What are things made of?What is the sun?Why is there night and day, winter and summer?Why do bad things happen?Are we alone?Throughout history people all over the world have invented stories to answer profound questions such as these. Have you heard the tale of how the sun hatched out of an emu's egg?

These 12 half-hour lectures are about what Einstein got wrong. He may have kindled a scientific revolution with his famous theory of relativity and his proof that atoms and light quanta exist, but he balked at accepting the most startling implications of these theories - such as the existence of black holes, the big bang, gravity waves, and mind-bendingly strange phenomena in the quantum realm. This course by research physicist Dan Hooper of the University of Chicago assumes no background in science and uses very little math.

Britain's most famous mathematician takes us to the edge of knowledge to show us what we cannot know. Science is king. Every week headlines announce new breakthroughs in our understanding of the universe, new technologies that will transform our environment, new medical advances that will extend our lives. Science is giving us unprecedented insight into some of the big questions that have challenged humanity ever since we've been able to formulate those questions.

Witness early, bloody, anaesthetic-free operations and first crude surgical instruments, trace the mapping of the circulatory system, follow the painstaking detective work that led to the decoding of the human genome and understand the role that potions, cures, therapies, herbal medicines and drugs have played in the human quest to tame and conquer disease, injury and death. An engrossing history and tale of drama and discovery that celebrates the milestones of medical history across generations and cultures.

Whether you live in a mountain cabin or a city loft, plant spirits present themselves to us everywhere. Since its first edition in 1995, Plant Spirit Medicine has passed among countless audiences drawn to indigenous spirituality and all things alive and green. In this updated edition, Eliot Cowan invites us to discover the healing power of plants - not merely their physical medicinal properties, but the deeper wisdom and gifts that they offer.

The atom. The big bang. DNA. Natural selection. All ideas that have revolutionised science - and that were dismissed out of hand when they first appeared. The surprises haven't stopped: here, Michael Brooks, best-selling author of 13 Things That Don't Make Sense, investigates the new wave of unexpected insights that are shaping the future of scientific discovery. Through 11 radical new insights, Brooks takes us to the extreme frontiers of what we understand about the world.

The fascinating science behind the eventual end to everything - from the individual to all existence. Although we may try to keep it tucked at the back of our minds, most of us are aware of our own mortality. But few among us know what science, with the help of insights yielded from groundbreaking new research, has to say about death on a larger scale. Enter astronomer Chris Impey, who chronicles the death of the whole shebang.

Stick and Rudder is the first exact analysis of the art of flying ever attempted. It has been continuously in print for 33 years. It shows precisely what the pilot does when he flies, just how he does it, and why. Because the basics are largely unchanging, the book therefore is applicable to large airplanes and small, old airplanes and new, and is of interest not only to the learner but also to the accomplished pilot and to the instructor himself.

Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. He takes listeners from Rome's pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted.
