Lawrence Krauss explores the greatest unanswered questions at the forefront of science today, and likely for the coming century and beyond.Internationally known theoretical physicist and bestselling author Lawrence Krauss explores science's greatest unanswered questions. Three of the most important words in science are "I don't know." Not knowing implies a Universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last five hundred years, yet many fundamental mysteries of existence persist: How did our Universe begin? How big is the Universe? Is time travel possible? What's at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it? These mysteries define the scientific forefront—the threshold of the unknown. To explore that threshold is to gain a deeper understanding of just how far science has progressed....

Beyond Star Trek

Internationally renowned, award-winning theoretical physicist, New York Times bestselling author of A Universe from Nothing, and passionate advocate for reason, Lawrence Krauss tells the dramatic story of the discovery of the hidden world of reality—a grand poetic vision of nature—and how we find our place within it.In the beginning there was light. But more than this, there was gravity. After that, all hell broke loose... In A Universe from Nothing, Krauss revealed how our entire universe could arise from nothing. Now, he reveals what that something—reality—is. And, reality is not what we think or sense—it's weird, wild, and counterintuitive; it's hidden beneath everyday experience; and its inner workings seem even stranger than the idea that something can come from nothing. In a landmark, unprecedented work of scientific history, Krauss leads us to the furthest reaches of space...

A gripping new scientific biography of the revered Nobel Prize–winning physicist (and curious character). Perhaps the greatest physicist of the second half of the twentieth century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. An immensely colorful persona in and out of the office, Feynman revolutionized our understanding of nature amid a turbulent life. Krauss presents that life—from the death of Feynman’s childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon—as seen through the science, providing a new understanding of the legacy of a man who has fascinated millions. An accessible reflection on the issues that drive physics today, Quantum Man captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules. Lawrence M. Krauss is the director of the Origins Initiative at Arizona State University and has written more than three hundred scientific publications and seven books, including The Physics of Star Trek and A Universe from Nothing. He lives in Tempe, Arizona, and Shaker Heights, Ohio. "Engaging…. Krauss explains scientific material in a clear, lively style that would have earned Feynman's approval…. A worthy addition to the Feynman shelf and a welcome follow-up to the standard-bearer, James Gleick's Genius." - Kirkus Reviews"Lawrence Krauss's wonderful biography manages to combine a rolling narrative with a crystal clear explanation of Richard Feynman's science. Its lively descriptions make both electromagnetism and quantum mechanics fun, while Krauss's personal reflections on his subject add a new level of insight into the man and his scientific legacy. Quantum Man is a masterpiece." - Walter Isaacson, author of *Einstein: His Life and Universe*"Such a charismatic figure deserves a charismatic, knowledgeable, and literate physicist as his warts-and-all biographer. Lawrence Krauss fits the bill admirably and rises to the challenge with style, panache, and deep understanding." - Richard Dawkins, author of The God Delusion and *The Greatest Show on Earth*"Seamlessly entwining colorful episodes of physics' most 'curious character' with wonderfully clear descriptions of Feynman's penetrating breakthroughs in quantum theory, Krauss's account is both entertaining and masterly. A great read." - Brian Greene, author of The Hidden Reality and *The Elegant Universe*"A lively and engrossing biography of a lively and engrossing man. Krauss recounts the life and ideas of one of the century's greatest scientist with a deep understanding of both the physics and the man, presented with great lucidity and charm." - Steven Pinker, Harvard College Professor of Psychology, Harvard University, and author of *How the Mind Works*
