WHAT HAPPENED BEFORE THE BIG BANG? A physics professor offers a theory about the ultimate origin of the universe—and challenges the concept of a multiverse, string theory, and more.In the beginning was the Big Bang: an unimaginably hot fire almost 14 billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in 20th-century science. And yet it leaves...

Inflationary Cosmology is an advanced graduate-level textbook, covering in detail the physics of inflation in the early universe, with a special focus on the physics of the curvature perturbation — the primordial seed for the formation of structure in the universe — generated by quantum vacuum fluctuations during inflation. The book covers in detail perturbation theory in General Relativity and semiclassical quantization of perturbations in inflation, and observational constraints on infla...

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent the...

How deep learning–from Google Translate to driverless cars to personal cognitive assistants–is changing our lives and transforming every sector of the economy.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 wo...

Throughout time, from ancient Rome to modern Britain, the great empires built and maintained their domination through force of arms and political power. But not the United States. America has dominated the world in a new, peaceful, and pervasive way—through the continued creation of staggering wealth. In this authoritative, engrossing history, John Steele Gordon captures as never before the true source of our nation's global influence: wealth and the capacity to create more of it.

Can we do better in space than we've done here on Earth?We've pinpointed the destination, refined the technology, designed the habitat. Are we forgetting something? A timely reminder that it's not just rocket science, this book explores the all-too-human issues raised by the prospect of settling in outer space. Accordingly, her work highlights the complex ethical challenges that accompany any other-worldly venture—questions about the environment, labor rig...

Deep learning is an artificial intelligence technology that enables computer vision, speech recognition in mobile phones, machine translation, AI games, driverless cars, and other applications. When we use consumer products from Google, Microsoft, Facebook, Apple, or Baidu, we are often interacting with a deep learning system. In this volume in the MIT Press Essential Knowledge series, computer scientist John Kelleher offers an accessible and concise but comprehensive introduction to the f...

Esteemed Egyptologist Barbara Mertz updates her widely praised social history of the people of ancient Egypt, which was originally published in 1968. Combining impeccable scholarship with a delightfully personal style, the author reconstructs the life of the Egyptians from birth to death, and beyond death, too. She also presents much fascinating detail on the building of the pyramids and the intricate art of mummification. Students and laymen alike will enjoy the wealth of authentic materi...

In the early 1800s, a century before there was any concept of the gene, physicians in insane asylums began to record causes of madness in their admission books. Almost from the beginning, they pointed to heredity as the most important of these causes. As doctors and state officials steadily lost faith in the capacity of asylum care to stem the terrible increase of insanity, they began emphasizing the need to curb the reproduction of the insane. They became obsessed with identifying weak or...

Unequal Gains offers a radically new understanding of the economic evolution of the United States, providing a complete picture of the uneven progress of America from colonial times to today. While other economic historians base their accounts on American wealth, Peter Lindert and Jeffrey Williamson focus instead on income-and the result is a bold reassessment of the American economic experience. America has been exceptional in its rising inequality after an egalitarian start, but not in i...

Opossums in the wild don't make it to the age of three; our pet cats can live for a decade and a half; cicadas live for seventeen years. Whales, however, can live for two centuries and tubeworms for several millennia. Meanwhile, human life expectancy tops out around the mid-eighties, with some outliers living past 100 or even 110. Is there anything humans can learn from the exceptional longevity of some animals in the wild? In Methusaleh's Zoo, Steven Austad tells the stories of s...
