In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

So much of our world seems to make perfect sense, and scientific breakthroughs have helped us understand ourselves, our planet, and our place in the universe in fascinating detail. But our adventures in space, our deepening understanding of the quantum world, and our leaps in technology have also revealed a universe far stranger than we ever imagined. With brilliant clarity and wit, best-selling author Marcus Chown examines the profound science behind 50 remarkable scientific facts that help explain the vast complexities of our existence.

Special-interest money is destroying our democratic process. But now that the Citizens United decision has thrown out campaign spending limits as abridgments of free speech, Americans want to know what they can do about it. Derek Cressman gives us the tools, both intellectual and tactical, to fight back. There's nothing inherently unconstitutional in limiting the amount of speech, Cressman insists.

Interweaving history, original reportage, and personal narrative, Pandemic explores the origin of epidemics, drawing parallels between the story of cholera - one of history's most disruptive and deadly pathogens - and the new pathogens that stalk humankind today, from Ebola and avian influenza to drug-resistant superbugs.

It has long been recognized that most standard of living increases are associated with advances in technology, not the accumulation of capital. Yet it has also become clear that what truly separates developed from less developed countries is not just a gap in resources or output but a gap in knowledge. In fact the pace at which developing countries grow is largely determined by the pace at which they close that gap. Therefore, how countries learn and become more productive is key to understanding how they grow and develop, especially over the long term.

Ranging from the Vikings and Wako pirates in the Middle Ages to modern day Somali pirates, Lehr delves deep into what motivates pirates and how they operate. He also illuminates the state's role in the development of piracy throughout history: from privateers sanctioned by Queen Elizabeth to pirates operating off the coast of Africa taking the law into their own hands. After exploring the structural failures which create fertile ground for pirate activities, Lehr evaluates the success of counter-piracy efforts - and the reasons behind its failures.

A bold and all-embracing exploration of the nature and progress of knowledge from one of today's great thinkers. Throughout history, mankind has struggled to understand life's mysteries, from the mundane to the seemingly miraculous. In this important new book, David Deutsch, an award-winning pioneer in the field of quantum computation, argues that explanations have a fundamental place in the universe.

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

As a major political event and a crucial turning point in the history of the People's Republic of China, the Great Proletarian Cultural Revolution (1966-1976) marked the zenith as well as the nadir of Mao Zedong's ultra-leftist politics. Reacting in part to the Soviet Union's "revisionism" that he regarded as a threat to the future of socialism, Mao mobilized the masses in a battle against what he called "bourgeois" forces within the Chinese Communist Party (CCP). This 10-year-long class struggle on a massive scale devastated traditional Chinese culture as well as the nation's economy.

Medical doctor and researcher Dr. Kris Verburgh is quickly emerging as one of the world's leading research authorities on the science of aging. The Longevity Code is his authoritative guide on why and how we age and on the four most crucial areas we have control over in order to slow down - and even reverse - the aging process. We learn why some animal species hardly age at all while others age and die very quickly and about the mechanisms at work that slowly but definitely cause our bodies to age, making us susceptible to heart attack, stroke, cancer, pneumonia, and dementia.

Imagine a world where the difference between man and machine blurs, where the line between humanity and technology fades, and where the soul and the silicon chip unite. This is not science fiction. This is the twenty-first century according to Ray Kurzweil, the “restless genius” (The Wall Street Journal), “ultimate thinking machine” (Forbes), and inventor of the most innovative and compelling technology of our era.

A sweeping account of the century of experimentation that confirmed Einstein's general theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory.

English is the world language, except that most of the world doesn’t speak it - only one in five people does. Dorren calculates that to speak fluently with half of the world’s 7.4 billion people in their mother tongues, you would need to know no fewer than 20 languages. He sets out to explore these top 20 world languages, which range from the familiar (French, Spanish) to the surprising (Malay, Javanese, Bengali).

For the first time in history, the secrets of the living brain are being revealed by a battery of high-tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.
