The international bestseller that inspired a major Nova special and sparked a new understanding of the universe, now with a new preface and epilogue.Brian Greene, one of the world's leading string theorists, peels away layers of mystery to reveal a universe that consists of eleven dimensions, where the fabric of space tears and repairs itself, and all matter—from the smallest quarks to the most gargantuan supernovas—is generated by the vibrations of microscopically tiny loops of energy. The Elegant Universe makes some of the most sophisticated concepts ever contemplated accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.

This is the classic layperson''s bible of mod ern physics for anyone who is fascinated but intimidated by the intellectual quantum leap into relativity and beyond. '

American Prometheus is the first full-scale biography of J. Robert Oppenheimer, “father of the atomic bomb,” the brilliant, charismatic physicist who led the effort to capture the awesome fire of the sun for his country in time of war. Immediately after Hiroshima, he became the most famous scientist of his generation–one of the iconic figures of the twentieth century, the embodiment of modern man confronting the consequences of scientific progress.He was the author of a radical proposal to place international controls over atomic materials–an idea that is still relevant today. He opposed the development of the hydrogen bomb and criticized the Air Force’s plans to fight an infinitely dangerous nuclear war. In the now almost-forgotten hysteria of the early 1950s, his ideas were anathema to powerful advocates of a massive nuclear buildup, and, in response, Atomic Energy Commission chairman Lewis Strauss, Superbomb advocate Edward Teller and FBI director J. Edgar Hoover worked behind the scenes to have a hearing board find that Oppenheimer could not be trusted with America’s nuclear secrets. American Prometheus sets forth Oppenheimer’s life and times in revealing and unprecedented detail. Exhaustively researched, it is based on thousands of records and letters gathered from archives in America and abroad, on massive FBI files and on close to a hundred interviews with Oppenheimer’s friends, relatives and colleagues. We follow him from his earliest education at the turn of the twentieth century at New York City’s Ethical Culture School, through personal crises at Harvard and Cambridge universities. Then to Germany, where he studied quantum physics with the world’s most accomplished theorists; and to Berkeley, California, where he established, during the 1930s, the leading American school of theoretical physics, and where he became deeply involved with social justice causes and their advocates, many of whom were communists. Then to Los Alamos, New Mexico, where he transformed a bleak mesa into the world’s most potent nuclear weapons laboratory–and where he himself was transformed. And finally, to the Institute for Advanced Study in Princeton, which he directed from 1947 to 1966.American Prometheus is a rich evocation of America at midcentury, a new and compelling portrait of a brilliant, ambitious, complex and flawed man profoundly connected to its major events–the Depression, World War II and the Cold War. It is at once biography and history, and essential to our understanding of our recent past–and of our choices for the future.

Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the general public. Here Feynman provides a classic and definitive introduction to QED (namely quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman clearly and humorously communicates both the substance and spirit of QED to the layperson. A. Zee's new introduction places both Feynman's book and his seminal contribution to QED in historical context and further highlights Feynman's uniquely appealing and illuminating style.

With a new Introduction by the author, the twenty-fifth anniversary edition of the Pulitzer Prize-winning epic about how the atomic bomb came to be.In rich, human, political, and scientific detail, here is the complete story of the nuclear bomb. Few great discoveries have evolved so swiftly--or have been so misunderstood. From the theoretical discussions of nuclear energy to the bright glare of Trinity there was a span of hardly more than twenty-five years. What began merely as an interesting speculative problem in physics grew into the Manhattan Project, and then into the Bomb with frightening rapidity, while scientists known only to their peers--Szilard, Teller, Oppenheimer, Bohr, Meitner, Fermi, Lawrence, and von Neumann--stepped from their ivory towers into the limelight. Richard Rhodes takes us on that journey step-by-step, minute by minute, and gives us the definitive story of man's most awesome discovery and invention. "The Making of the Atomic Bomb" is at once a narrative tour de force and a document as powerful as its subject.

The universe has its secrets. It may even hide extra dimensions, different from anything ever imagined. A whole raft of remarkable concepts now rides atop the scientific firmament, including parallel universes, warped geometry, and threedimensional sink-holes. We understand far more about the world than we did just a few short years ago -- and yet we are more uncertain about the true nature of the universe than ever before. Have we reached a point of scientific discovery so advanced that the laws of physics as we know them are simply not sufficient? Will we all soon have to accept explanations that previously remained in the realm of science fiction? Lisa Randall is herself making these extraordinary breakthroughs, pushing back the boundaries of science in her research to answer some of the most fundamental questions posed by Nature. For example, why is the gravitational field from the entire Earth so defenseless against the small tug of a tiny magnet? Searching for answers to such seemingly irresolvable questions has led physicists to postulate extra dimensions, the presence of which may lead to unimaginable gains in scientific understanding. Randall takes us into the incredible world of warped, hidden dimensions that underpin the universe we live in, describing how we might prove their existence, while examining the questions that they still leave unanswered. Warped Passages provides an exhilarating overview that tracks the arc of discovery from early twentieth-century physics to the razor's edge of today's particle physics and string theory, unweaving the current debates about relativity, quantum mechanics, and gravity. In a highly readable style sure to entertain and elucidate, Lisa Randall demystifies the science and beguilingly unravels the mysteries of the myriad worlds that may exist just beyond the one we are only now beginning to know.
