Growth has been both an unspoken and an explicit aim of our individual and collective striving. It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.

Why did humans abandon hunting and gathering for sedentary communities dependent on livestock and cereal grains and governed by precursors of today's states? Most people believe that plant and animal domestication allowed humans, finally, to settle down and form agricultural villages, towns, and states, which made possible civilization, law, public order, and a presumably secure way of living. But archaeological and historical evidence challenges this narrative.

The most urgent story in modern tech begins not in Silicon Valley but two hundred years ago in rural England, when workers known as the Luddites rose up rather than starve at the hands of factory owners who were using automated machines to erase their livelihoods. The Luddites organized guerrilla raids to smash those machines—on punishment of death—and won the support of Lord Byron, enraged the Prince Regent, and inspired the birth of science fiction. This all-but-forgotten class struggle brought nineteenth-century England to its knees.

I know my own mind. I am able to assess others in a fair and accurate way. These self-perceptions are challenged by leading psychologists Mahzarin R. Banaji and Anthony G. Greenwald as they explore the hidden biases we all carry from a lifetime of exposure to cultural attitudes about age, gender, race, ethnicity, religion, social class, sexuality, disability status, and nationality. Blindspot is the authors’ metaphor for the portion of the mind that houses hidden biases.

Want to know how AT&T's Bell Labs developed semiconductor technology - and how its leading scientists almost came to blows in the process? Want to understand how radio and television work - and why RCA drove their inventors to financial ruin and early graves? Conquering the Electron offers these stories and more, presenting each revolutionary technological advance right alongside blow-by-blow personal battles that all too often took place.

From leading geopolitical expert and technology futurist Jamie Metzl comes a groundbreaking exploration of the many ways genetic engineering is shaking the core foundations of our lives-sex, war, love, and death. At the dawn of the genetics revolution, our DNA is becoming as readable, writable, and hackable as our information technology. But as humanity starts retooling our own genetic code, the choices we make today will be the difference between realizing breathtaking advances in human well-being and descending into a dangerous and potentially deadly genetic arms race.

Balancing a broad array of archaeological, botanical, and historical evidence, Fruit from the Sands presents the fascinating story of the origins and spread of agriculture across Inner Asia and into Europe and East Asia. Through the preserved remains of plants in archaeological sites, Robert N. Spengler III identifies the regions where our most familiar crops were domesticated and follows their routes as people carried them around the world. Vividly narrated, Fruit from the Sands explores how the foods we eat have shaped the course of human history.

This sweeping exploration of the impact of epidemic diseases looks at how mass infectious outbreaks have shaped society, from the Black Death to today, and in a new preface addresses the global threat of COVID-19. In a clear and accessible style, Frank M. Snowden reveals the ways that diseases have not only influenced medical science and public health, but also transformed the arts, religion, intellectual history, and warfare.

In this Very Short Introduction audiobook, Jan Zalasiewicz gives a brief introduction to the fascinating field of geology. Describing how the science developed from its early beginnings, he looks at some of the key discoveries that have transformed it before delving into its various subfields, such as sedimentology, tectonics, and stratigraphy.

Physics, the fundamental science of matter and energy, encompasses all levels of nature from the subatomic to the cosmic, and underlies much of the technology around us. Understanding the physics of our universe is an essential aspect of humanity's quest to understand our environment and our place within it. Doing physics enables us to explore the interaction between environment and human society, and can help us to work towards the future sustainability of the planet.

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.

Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how.

What to Do When Machines Do Everything is a guidebook to succeeding in the next generation of the digital economy. When systems running on artificial intelligence can drive our cars, diagnose medical patients, and manage our finances more effectively than humans, it raises profound questions on the future of work and how companies compete.

On July 22, 2009, a special meeting was held with 24 leading scientists at the National Institutes of Health to discuss early findings that a newly discovered retrovirus was linked to chronic fatigue syndrome (CFS), prostate cancer, lymphoma, and eventually neurodevelopmental disorders in children. When Dr. Judy Mikovits finished her presentation the room was silent for a moment, then one of the scientists said, "Oh my God!" The resulting investigation would be like no other in science.

A short and entertaining introduction to thermodynamics that uses real-world examples to explain accessibly an important but subtle scientific theory.

From the cup of coffee that jump-starts the day to dangerously addictive drugs, the recreational use of plants with psychoactive properties has a long history among humans. But, as with many things, it turns out that other animals got there first. From parrots to primates, consuming medicinal chemicals is an instinctive behavior that helps countless organisms fight infection and treat disease. But the similarities don't end there: Like us, many creatures also consume substances that have no apparent benefit...except for inducing intoxication.

In Longshot, investigative journalist David Heath takes listeners inside the small group of scientists whose groundbreaking work was once largely dismissed but whose feat will now eclipse the importance of Jonas Salk’s polio vaccine in medical history. With never-before-reported details, Heath reveals how these scientists overcame countless obstacles to give the world an unprecedented head start when we needed a COVID-19 vaccine.

During his remarkable lifetime, Harold Gatty became one of the world's great navigators (in 1931, he and Wiley Post flew around the world in a record-breaking eight days) and, to the benefit of posterity, recorded in this book much of his accumulated knowledge about pathfinding both on land and at sea. Applying methods used by primitive peoples and early explorers, the author reveals how to determine location, study wind directions and reflections in the sky, even how to use the senses of smell and hearing to find your way in the wilderness, in a desert, in snow-covered areas, and on the ocean.

Gold was discovered in the Klondike in August 16, 1896. When news of the discovery arrived in Seattle and San Francisco the following year it triggered one of the largest gold rushes in the history of North America. Tappan Adney, a young writer and photographer who worked for Harper's Weekly, set out on a journey to uncover and record what it was like in the Klondike stampede. This audiobook is a fascinating portrayal of adventurers and prospectors who descended on the Yukon during this extraordinary event in the late 19th century.
