When scientists peer through a telescope at the distant stars in outer space or use a particle-accelerator to analyze the smallest components of matter, they discover that the same laws of physics govern the whole universe at all times and all places. Physicists call the eternal, ubiquitous constancy of the laws of physics symmetry. Symmetry is the basic underlying principle that defines the laws of nature and hence controls the universe. This all-important insight is one of the great conceptual breakthroughs in modern physics and is the basis of contemporary efforts to discover a grand unified theory to explain all the laws of physics. Nobel Laureate Leon M. Lederman and physicist Christopher T. Hill explain the supremely elegant concept of symmetry and all its profound ramifications to life on Earth and the universe at large in this eloquent, accessible popular science book. They not only clearly describe concepts normally reserved only for physicists and mathematicians, but they also instill an appreciation for the profound beauty of the universe’s inherent design. Central to the story of symmetry is an obscure, unpretentious, but extremely gifted German mathematician named Emmy Noether. Though still little known to the world, she impressed no less a scientist than Albert Einstein, who praised her "penetrating mathematical thinking." In some of her earliest work she proved that the law of the conservation of energy was connected to the idea of symmetry and thus laid the mathematical groundwork for what may be the most important concept of modern physics. Lederman and Hill reveal concepts about the universe, based on Noether’s work, that are largely unknown to the public and have wide-reaching implications in connection with the Big Bang, Einstein’s theory of relativity, quantum mechanics, and many other areas of physics. Through ingenious analogies and illustrations, they bring these astounding notions to life. This book will open your eyes to a universe you never knew existed.
An engaging exploration of beauty in physics, with a foreword by Nobel Prize–winning physicist Roger Penrose The concept of symmetry has widespread manifestations and many diverse applications—from architecture to mathematics to science. Yet, as twentieth-century physics has revealed, symmetry has a special, central role in nature, one that is occasionally and enigmatically violated. Fearful Symmetry brings the incredible discoveries of the juxtaposition of symmetry and asymmetry in contemporary physics within everyone's grasp. A. Zee, a distinguished physicist and skillful expositor, tells the exciting story of how contemporary theoretical physicists are following Einstein in their search for the beauty and simplicity of Nature. Animated by a sense of reverence and whimsy, Fearful Symmetry describes the majestic sweep and accomplishments of twentieth-century physics—one of the greatest chapters in the intellectual history of humankind.
Higgs Force tells the dramatic story of how physicists produced their modern understanding of the Cosmos by unlocking the secrets of matter. Physicists believe that the universe began in a state of perfect symmetry. As the universe expanded and the temperature fell, much of this symmetry was lost in an all-encompassing transformation. We see the results all around us - the evolution of a complex and dynamic universe supporting the existence of sentient life. Deep beneath the Franco-Swiss border, CERN, with the mighty Large Hadron Collider, is seeking the ultimate confirmation of these ideas - the elusive Higgs particle, known to some as the God Particle.
This is a textbook that derives the fundamental theories of physics from symmetry. It starts by introducing, in a completely self-contained way, all mathematical tools needed to use symmetry ideas in physics. Thereafter, these tools are put into action and by using symmetry constraints, the fundamental equations of Quantum Mechanics, Quantum Field Theory, Electromagnetism, and Classical Mechanics are derived. As a result, the reader is able to understand the basic assumptions behind, and the connections between the modern theories of physics. The book concludes with first applications of the previously derived equations. Thanks to the input of readers from around the world, this second edition has been purged of typographical errors and also contains several revised sections with improved explanations.
"Since the first edition of the book appeared in 1979 major developments have occurred, with the discovery of yet more particles and the emergence of novel theoretical ideas. Most exciting is the recent progress towards a unified description of the forces of nature, which received a major boost when the so-called W and Z particles were found in 1983. Other promising advances include the study of grand unified theories (GUTs) with their predictions of magnetic monopoles and proton decay, and their sweeping implications for our understanding of the very early stages of the universe."--Page 4 de la couverture.
Symmetry provides an insight into the way nature works and is often used by scientists and technologists to help solve problems. Symmetry has numerous other applications as well — with more being discovered all the time in science, the arts and other fields of human endeavor. This classic work provides an excellent introduction to the basic concepts and terminology (including, optionally, group theory), as well as lucid discussions of geometric symmetry, other symmetries and appropriate symmetry, symmetry in nature, uses of symmetry in science and much more. Readers wishing to pursue specific topics will find many references that reflect the author's wide reading in the subject and his own obvious enthusiasm. For this edition, Dr. Rosen has provided a new preface, solutions to the problems, and an addendum to the bibliography.
In a vibrant exchange of letters between the author and a University Psychology Major over a three year period, issues of social pressure, the human soul and the metaphysical underpinnings of life are explored and discussed. An interesting and revealing read for anyone whos sincerely in touch with, and sensitive to, the yearnings of their own, individual soul. The author gets his first chance to present his understandings about the intentions of the universe and how it has been structured to reach its goals. In his opinion, all of the end-of-the-world-as-we-know-it scenarios were presently encountering are but the notification from the universe itself of a major paradigm shift in our reality. He presents all of his ideas in a clean and simple manner and formulates a unique understanding about life that wants to remain dogma-free. And it seems to work . . .
“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
From Simon & Schuster, Superforce is Paul Davies' latest work that searches for a grand unified theory of nature. Superforce explains how recent discoveries in physics and the new cosmology have transformed concepts of the physical world by linking space, time, matter, force, creation, order, and mind into the ultimate scientific theory.
