The Nobel Prize-winning physicist and bestselling author of The First Three Minutes describes the grand quest for a unifying theory of nature--one that can explain forces as different as the cohesion inside the atom and the gravitational tug between the sun and Earth. Wirting with dazzling elegance and clarity, he retraces the steps that have led modern scientists from relativity and quantum mechanics to the notion of super-strings and the idea that our universe may coexist with others. But Weinberg asks as many questions as he answers, among them: Why does each explanation of the way nature works point to other, deeper explanations? Why are the best theories not only logical but beautiful? And what implications will a final theory have for our philosophy and religious faith? Intellectually daring, rich in anecdote and aphorism, Dreams of a Final Theory launches us into a new cosmos and helps us make sense of what we find there.

When his physicist mentor is murdered for his possible knowledge about Einstein's Unified Field Theory, physics professor David Swift is swept up by a violent struggle for control of the information and its staggering potential.

"God does not play dice with the universe." So said Albert Einstein in response to the first discoveries that launched quantum physics, as they suggested a random universe that seemed to violate the laws of common sense. This 20th-century scientific revolution completely shattered Newtonian laws, inciting a crisis of thought that challenged scientists to think differently about matter and subatomic particles.The Dreams That Stuff Is Made Of compiles the essential works from the scientists who sparked the paradigm shift that changed the face of physics forever, pushing our understanding of the universe on to an entirely new level of comprehension. Gathered in this anthology is the scholarship that shocked and befuddled the scientific world, including works by Niels Bohr, Max Planck, Werner Heisenberg, Max Born, Erwin Schrodinger, J. Robert Oppenheimer, Richard Feynman, as well as an introduction by today's most celebrated scientist, Stephen Hawking.

NATIONAL BESTSELLER • A modern classic explores the connections between science and art, the process of creativity, and ultimately the fragility of human existence. “A magical, metaphysical realm ... Captivating, enchanting, delightful.” —The New York Times Einstein’s Dreams is a fictional collage of stories dreamed by Albert Einstein in 1905, about time, relativity and physics. As the defiant but sensitive young genius is creating his theory of relativity, a new conception of time, he imagines many possible worlds. In one, time is circular, so that people are fated to repeat triumphs and failures over and over. In another, there is a place where time stands still, visited by lovers and parents clinging to their children. In another, time is a nightingale, sometimes trapped by a bell jar. Now translated into thirty languages, Einstein’s Dreams has inspired playwrights, dancers, musicians, and painters all over the world. In poetic vignettes, it explores the connections between science and art, the process of creativity, and ultimately the fragility of human existence.

“The phrase ‘public intellectual’ is much bandied about. Just a few real heavyweights in the world merit the title, and Steven Weinberg is preeminent among them.” —Richard Dawkins “Weinberg has a knack for capturing a complex concept in a succinct, unforgettable image... One of the smartest and most diligent scientists around.” —Nature In this wise and wide-ranging meditation, one of the most captivating science communicators of our time challenges us to reconsider the entanglement of science and society. From the cosmological to the personal, from astronomy and quantum physics to the folly of manned spaceflight and the rewards of getting things wrong, Steven Weinberg shares his views on the workings of the universe and our aspirations and limitations. Third Thoughts aims to provoke and inform and never loses sight of the human dimension of scientific discovery. “One of the 20th century’s greatest physicists...shares his strongly-held opinions on everything from the Higgs boson to the state of theoretical physics and the problems of science and society.” —Forbes “This book should be read not only for its insightful and illuminating explanations of a wide range of physical phenomena but also for the opportunity it affords to follow the wanderings of a brilliant mind through topics ranging from high-energy physics and the makeup of the cosmos to poetry, and from the history and philosophy of science to the dangers of economic inequality... [A] captivating book.” —Mario Livio, Science

Thirty years ago Albert Einstein died, his dream of a theory that would unify the universe unfulfilled. He spent the last decades of his life searching for such a theory-a theory that would explain everything from elementary particles and their interac tions to the overall structure of the universe. But he failed, not because he didn't try hard enough, but because the attempt was ahead of its time. When Einstein worked on the problem liter ally nothing was known about black holes, white holes, sin gularities, the Big Bang explosion and the early universe, quarks, gauge invariance, and weak and strong nuclear forces. Today we know that all these things are important in relation to a unified theory, and that they must be incorporated in and explained by such a theory. Thus, in a sense, our problem is much more complex today than it was in Einstein's day. But scientists have persevered and as a result we are now tan talizingly close to achieving this long-sought goal. Important breakthroughs have been made. In this book we will look at these breakthroughs and at recent unified theories-theories that go by the names supergravity, superstrings, GUTs, and twistor theory. In order to understand the problem, however, we must begin at the beginning.

Available for the first time in paperback, The Quantum Theory of Fields is a self-contained, comprehensive, and up-to-date introduction to quantum field theory from Nobel Laureate Steven Weinberg. Volume I introduces the foundations of quantum field theory. The development is fresh and logical throughout, with each step carefully motivated by what has gone before. After a brief historical outline, the book begins with the principles of relativity and quantum mechanics, and the properties of particles that follow. Quantum field theory emerges from this as a natural consequence. The classic calculations of quantum electrodynamics are presented in a thoroughly modern way, showing the use of path integrals and dimensional regularization. It contains much original material, and is peppered with examples and insights drawn from the author's experience as a leader of elementary particle research. Exercises are included at the end of each chapter.

"A truly comprehensive, scientifically rigorous and utterly fascinating account of when, how, and why we dream. Put simply, When Brains Dream is the essential guide to dreaming." —Matthew Walker, author of Why We Sleep Questions on the origins and meaning of dreams are as old as humankind, and as confounding and exciting today as when nineteenth-century scientists first attempted to unravel them. Why do we dream? Do dreams hold psychological meaning or are they merely the reflection of random brain activity? What purpose do dreams serve? When Brains Dream addresses these core questions about dreams while illuminating the most up-to-date science in the field. Written by two world-renowned sleep and dream researchers, it debunks common myths that we only dream in REM sleep, for example—while acknowledging the mysteries that persist around both the science and experience of dreaming. Antonio Zadra and Robert Stickgold bring together state-of-the-art neuroscientific ideas and findings to propose a new and innovative model of dream function called NEXTUP—Network Exploration to Understand Possibilities. By detailing this model’s workings, they help readers understand key features of several types of dreams, from prophetic dreams to nightmares and lucid dreams. When Brains Dream reveals recent discoveries about the sleeping brain and the many ways in which dreams are psychologically, and neurologically, meaningful experiences; explores a host of dream-related disorders; and explains how dreams can facilitate creativity and be a source of personal insight. Making an eloquent and engaging case for why the human brain needs to dream, When Brains Dream offers compelling answers to age-old questions about the mysteries of sleep.
