There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Few perspectives epitomize the sheer drama and sacrifice of combat more perfectly than those of the fighter pilots of World War II. As romanticized as any soldier in history, the World War II fighter pilot was viewed as larger than life: a dashing soul waging war amongst the clouds. In the 65-plus years since the Allied victory, stories of these pilots' heroics have never been in short supply. But what about their adversaries - the highly skilled German aviators who pushed the Allies to the very brink of defeat?

We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often - 200 times more often than a dog does? How come our wrists have so many useless bones? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last.

Drawing on 40 years of research and a treasure trove of new information, Tesla: Wizard at War provides a comprehensive view of Tesla's discoveries, which continue to influence today's military technology and diplomatic strategies. One of the world's leading Tesla experts, Marc J. Seifer, offers new insight into the brilliant scientist's particle beam weapon (aka the "Death Ray") and explores his military negotiations with pivotal historical figures - including his links to Joseph Stalin, Vannevar Bush, General Andrew McNaughton, and Franklin Delano Roosevelt.

The deep-learning revolution has brought us driverless cars, the greatly improved Google Translate, fluent conversations with Siri and Alexa, and enormous profits from automated trading on the New York Stock Exchange. Deep-learning networks can play poker better than professional poker players and defeat a world champion at Go. In this book, Terry Sejnowski explains how deep learning went from being an arcane academic field to a disruptive technology in the information economy.

For modern science, the transitional states of consciousness lie at the forefront of research in many fields. For a Buddhist practitioner, these same states present crucial opportunities to explore and transform consciousness itself. This book is the account of a historic dialogue between leading Western scientists and the Dalai Lama of Tibet. Revolving around three key moments of consciousness - sleep, dreams, and death - the conversations recorded here are both engrossing and highly listenable.

When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices - or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical.

J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

In Aware, New York Times best-selling author Daniel J Siegel introduces listeners to his life-changing meditation program, 'The Wheel of Awareness'. Whether the listener has no experience with reflective practices or is an experienced practitioner, Aware provides practical instruction for mastering this brilliant tool for cultivating more focus, presence and peace in one's day-to-day life. Dr. Siegel reveals in this fascinating audiobook how mindfulness practices such as meditation have the capacity to quite literally rewire our brains, as 'neurons that fire together wire together'.

Over half a century ago, John Rowlands set out by canoe into the wilds of Canada to survey land for a timber company. After paddling alone for several days, he came upon "the lake of my boyhood dreams", which he named Cache Lake because there was stored the best that the north had to offer-timber for a cabin; fish, game, and berries to live on; and the peace and contentment he felt he could not live without.

Written by the legendary officer who shot these lions and risked death several times in the attempt, The Man-Eaters of Tsavo is not only the story of this breathtaking hunt, but of Lieutenant-Colonel Patterson's other adventures in the African bush.

Nikola Tesla (1856-1943), credited as the inspiration for radio, robots, and even radar, has been called the patron saint of modern electricity. Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology.

Hidden in the names of English towns and villages, in copses, fields, lanes and hills, are the ghostly traces of birds conjuring powerful identities for people in ancient landscapes. What are their stories and secrets? How did people encounter birds over a thousand years ago? In The Cuckoo’s Lea, Michael J. Warren sets out on the trail of these ghosts. Captivated and guided by the secrets of place names, he finds their stories entangled with his own explorations of places through birds all across England.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

The Sexual Politics of Meat is Carol Adams’ inspiring and controversial exploration of the interplay between contemporary society’s ingrained cultural misogyny and its obsession with meat and masculinity. First published in 1990, the book has continued to change the lives of tens of thousands of people into the second decade of the 21st century.

Today's kids have adopted sedentary lifestyles filled with television, video games, and computer screens. But more and more, studies show that children need "rough and tumble" outdoor play in order to develop their sensory, motor, and executive functions. Disturbingly, a lack of movement has been shown to lead to a number of health and cognitive difficulties, such as attention deficit/hyperactivity disorder (ADHD), emotion regulation and sensory processing issues, and aggressiveness at school recess break.

Why are we drawn to the ocean each summer? Why does being near water set our minds and bodies at ease? In Blue Mind, Wallace J. Nichols revolutionizes how we think about these questions, revealing the remarkable truth about the benefits of being in, on, under, or simply near water.

The last century saw a revolution in life expectancy. Whether you are male or female, born in the global south or north, the chances are that you can expect to live much longer than previous generations. But instead of seeing this as a precious gift of extra life, we see it as a burden, with ageing populations dogged by infirmity, dependent on an ever-decreasing number of young people to support them. Andrew Scott argues it doesn't have to be like that.

Modern diseases and viruses have been spurred anew by war and conflict as well as shifting poverty, urbanization, climate change, and a new troubling anti-science/anti-vaccination outlook. From such 21st-century forces, we have seen declines in previous global health gains, with sharp increases in vaccine-preventable and neglected diseases. International vaccine scientist and tropical disease and coronavirus expert Peter J. Hotez, MD, PhD, argues that we can - and must - rely on vaccine diplomacy to address this new world order in disease and global health.

Scientists are learning more and more about how brain activity controls behavior and how neural circuits weigh alternatives and initiate actions. As we probe ever deeper into the mechanics of decision making, many conclude that agency—or free will—is an illusion. In Free Agents, leading neuroscientist Kevin Mitchell presents a wealth of evidence to the contrary, arguing that we are not mere machines responding to physical forces but agents acting with purpose.
