Frames superstrings and twistors.......2000-04-29
Gardner's account of Roger Penrose's twistor theory is short and excellent. Physicists have gotten tangled up trying to speak of deeper down events which are hidden from view due to their sub-Planck length size (10 to the minus 33rd power of a centimeter). Here it is pointed out that "on a sufficiently small scale the concept of a space-time point evaporates in the complex space of twistor theory." Twistor theory, like superstring theory, was merely trying to formulate how the submicroscopic particles come into being. Both theories consist of math and lack any experimental verification. To repeat, the author discusses these obtuse theories in a way that frames their overall direction of thought. Gardner appears to agree with Howard George who calls superstring theory a "recreational mathematical theology." The bottom line -- both twistor and string theory are philosophy -- not physics.

Gravitation: From the Hubble Length to the Planck Length (Studies in High Energy Physics, Cosmology and Gravitation)
Manufacturer: Taylor & Francis ProductGroup: Book Binding: Hardcover ASIN: 0750309482 |
Book Description
Although gravity is the dominant force of nature at large distances (from intermediate scales to the Hubble length), it is the weakest of forces in particle physics, though it is believed to become important again at very short scales (the Planck length). The conditions created in particle accelerators are similar to those at the time of the early universe. While particle physics offers insight to early universe physics, there is a need to understand gravity at extremes of large and short distances to further understand cosmology and the development of the universe. Gravitation: From the Hubble Length to the Planck Length fulfills this need by providing an overview of relativistic astrophysics, early universe physics, cosmology, and their interface with particle physics. Written by international experts, this reference presents up-to-date information on classical relativity, astrophysics, and theoretical and experimental particle physics. The introduction sets the scene and provides a context for the remaining chapters. Chapters cover an extensive array of topics, from refined experimental techniques in gravitational physics to cosmology and the quantum frontier. The book concludes with a discussion of the connection among particles, fields, strings, and branes. This compilation shows how gravity plays a fundamental role in astronomy, astrophysics, and cosmology by exploring domains from the microscopic, such as black holes, to superclusters of galaxies that form the large-scale texture of the present-day cosmos. Moreover, with its theoretical and experimental focus on the foundations of gravity, Gravitation proves to be an invaluable resource for current and future research.

Understanding the Universe: From Quarks to the Cosmos
Don Lincoln Manufacturer: World Scientific Publishing Company ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 9812387056 |
Book Description
The Big Bang, the birth of the universe, was a singular event. All of the matter of the universe was concentrated at a single point, with temperatures so high that even the familiar protons and neutrons of atoms did not yet exist, but rather were replaced by a swirling maelstrom of energy, matter and antimatter. Exotic quarks and leptons flickered briefly into existence, before merging back into the energy sea.This book explains the fascinating world of quarks and leptons and the forces that govern their behavior. Told from an experimental physicist's perspective, it forgoes mathematical complexity, using instead particularly accessible figures and apt analogies. In addition to the story of quarks and leptons, which are regarded as well-accepted fact, the author who is a leading researcher at the world's highest energy particle physics laboratory also discusses mysteries on both the experimental and theoretical frontier, before tying it all together with the exciting field of cosmology and indeed the birth of the universe itself.
The text spans the tiny world of the quark to the depths of the universe with exceptional clarity. The casual student of science will appreciate the careful distinction between what is known (quarks, leptons and antimatter), what is suspected (Higgs bosons, neutrino oscillations and the reason why the universe has so little antimatter) and what is merely dreamed (supersymmetry, superstrings and extra dimensions). Included is an unprecedented chapter explaining the accelerators and detectors of modern particle physics experiments. The chapter discussing the hunt for the Higgs boson, currently consuming the efforts of nearly 1000 physicists, lends drama that only big-stakes science can give. Understanding the Universe leaves the reader with a deep appreciation of the fascinating particle realm and just how much it determines the rich beauty of our universe.

A Thin Cosmic Rain: Particles From Outer Space
Michael W. Friedlander Manufacturer: Harvard University Press ProductGroup: Book Binding: Hardcover ASIN: 0674002881 |
Book Description
Enigmatic for many years, cosmic rays are now known to be not rays at all, but particles, the nuclei of atoms, raining down continually on the earth, where they can be detected throughout the atmosphere and sometimes even thousands of feet underground. This book tells the long-running detective story behind the discovery and study of cosmic rays, a story that stretches from the early days of subatomic particle physics in the 1890s to the frontiers of high-energy astrophysics today.
Writing for the amateur scientist and the educated general reader, Michael Friedlander, a cosmic ray researcher, relates the history of cosmic ray science from its accidental discovery to its present status. He explains how cosmic rays are identified and how their energies are measured, then surveys current knowledge and theories of thin cosmic rain. The most thorough, up-to-date, and readable account of these intriguing phenomena, his book makes us party to the search into the nature, behavior, and origins of cosmic rays—and into the sources of their enormous energy, sometimes hundreds of millions times greater than the energy achievable in the most powerful earthbound particle accelerators. As this search led unexpectedly to the discovery of new particles such as the muon, pion, kaon, and hyperon, and as it reveals scenes of awesome violence in the cosmos and offers clues about black holes, supernovas, neutron stars, quasars, and neutrinos, we see clearly why cosmic rays remain central to an astonishingly diverse range of research studies on scales infinitesimally small and large.
Attractively illustrated, engagingly written, this is a fascinating inside look at a science at the center of our understanding of our universe.

From Quarks to Black Holes: Interviewing the Universe
Richard T. Hammond Manufacturer: World Scientific Publishing Company ProductGroup: Book Binding: Hardcover ASIN: 9810246250 |
Book Description
This book presents a series of delightful interviews in which natural objects such as an electron, a black hole, a galaxy, and even the vacuum itself, reveal their innermost secrets - not only what they are but also how they feel. A hydrogen atom tells us about quantum mechanics and why we live in a non-deterministic world; a black hole explains curved space and naked singularities; and a uranium atom talks of its life on a meteor, its tremendous collision with Earth, and properties of radioactivity - all while grappling with its own mortality. A neutron star gives a personal account of its creation and goes on to discuss quasars and other extraordinary astronomical objects, while an iron atom describes its birth in a remote supernova explosion and its series of adventures on Earth, from its early use in wrought iron processes to its time in a human body, and then to its latest misadventures.The book discusses many fundamental issues in physics and, at times, examines the philosophical and moral issues of society. For example, the interview with the quark reveals the nature of color gauge symmetry, which is interwoven with a discussion on truth and beauty, and shows how these concepts play an integral part in physics and nature, while the uranium atom expresses its horror of the development and use of the atomic bomb.
