Available in PDF, EPUB and Kindle. Book excerpt: Ten years have passed since It Hooft and Polyakov demonstrat ed that superheavy magnetic monopoles were a natural consequence of any Grand Unified Theory (GUT) in which the unifying group contains a U(l) factor as a subgroup. An analysis of these GUTs in an expanding, cooling universe yields a phase transition at an energy ~l015 GeV and at a cosmic time ~lO-35 seconds after the big bang. The general consequences of GUTs and this phase transition are the prediction of proton decay, the production of superheavy magnetic monopoles, and an understanding of the observed excess of matter over anti-matter in the universe. Attempts to provide experimental verification of GUTs has led to valiant experimental efforts in recent years to observe nucleon decay in massive underground detectors. Experiments to search for superheavy monopoles may eventually require similar efforts. Since the unification scale is unreachable in the laboratory, monopole detectors must search for relics of the big bang. Much theoretical groundwork has been accomplished in recent years with the development of GUTs. In Part I of this book, Erick Weinberg gives a theoretical overview of the role of magnetic monopoles in the various unification schemes. Monopoles in the context of the newly revived Kaluza-Klein theories are presented by several authors and are summarized by Qaisar Shafi. Mike Turner begins Part II with a discussion of monopoles in standard big bang cosmology. Paul Steinhardt follows with his perspectives on the inflationary universe; C.
Download or read book Magnetic Monopoles written by Richard A. Carrigan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1269 Petrus Peregrinus observed lines of force around a lodestone and noted that they were concentrated at two points which he designated as the north and south poles of the magnet. Subsequent observation has confirmed that all magnetic objects have paired regions of' opposite polarity, that is, all magnets are dipoles. It is easy to conceive of an isolated pole, which J.J. Thomson did in 1904 when he set his famous problem of the motion of an electron in the field of a magnetic charge. In 1931 P.A.M. Dirac solved this problem quantum mechanically and showed that the existence of a single magnet pole anywhere in the universe could explain the mystery of charge quantization. By late 1981, theoretical interest in monopoles had reached the point where a meeting was organized at the International Centre for Theoretical Physics in Trieste. Many mathematical properties of monopoles were discussed at length but there was only a solitary account describing experiments. This imbalance did not so much reflect the meeting's venue as it indicated the relative theoretical and experimental effort at that point.

Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation of the literature concerning all aspects of astronomy, astrophysics, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 39 records literature published in 1985 and received before August 15, 1985. Some older documents which we received late and which are not surveyed in earlier volumes are included too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organiza tions, observatories, and publishers which provide us with complimentary copies of their publications. On account of the introduction of an object index the scope of index information will be considerably enlarged beginning with this volume. In connection with the subject index an additional source to satisfy the needs of retrieval is opened up. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Mona El-Choura, Ms. Monika Kohl, Ms. Sylvia Matyssek. Ms. Karin Burkhardt, Ms. Susanne Schlotelburg, and Mr. Stefan Wagner supported our task by careful proofreading. It is a pleasure to thank them all for their encouragement.

Available in PDF, EPUB and Kindle. Book excerpt: Recent discoveries in astronomy have revolutionized the field of cosmology. While many long-standing questions in cosmology have now been answered, the new data pose new mysteries such as the nature of the "dark energy" that dominates the universe. This second edition provides an accessible and thorough text on the physics of cosmology and a lively account of the modern concordance model of the universe, from the big bang to a distant future dominated by dark energy.

Download or read book Not by Design written by Victor J. Stenger and published by Prometheus Books. This book was released on 2010-10-05 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the world seems chaotic and unpredictable, but the regular movement of celestial bodies and certain demonstrable physical phenomena seem to indicate the existence of a world that is basically orderly. This orderliness is often taken as evidence for an intelligence beyond our experience - a "creator" responsible for the first moment in time and all ensuing infinite patterns of the universe. Yet the science of the origin of the universe is still highly speculative and incomplete. How did the universe begin? According to Professor Victor J. Stenger, the simplest hypothesis so far is that it began by accident. Stenger insists that the existence of order does not necessarily imply that it is the result of design. Nothing currently known about the universe, he writes, requires that its structure was somehow imposed upon it from the outside. The universe is complex, but the laws of nature are simple; in fact, the universe may have originated because of a series of spontaneous random events. The book begins with a discussion of the meaning of order and examples of orderly patterns generated by chance. (Play enough poker hands, Stenger writes, and one day you will be dealt four aces.) Subsequent chapters introduce readers to the unique perspective of the universe provided by physics, with historical and philosophical material intertwined with a systematic but nontechnical presentation of basic physics. This leads to a description of the basic structure of the universe and the way in which symmetries of space, time, and inner dimensions account for the "laws" obeyed by particles. The origin of the universe is then described as a chance event, with space, time, matter, and the laws of nature the result of a spontaneous process of symmetry-breaking. Focusing on the question of planned versus unplanned origin, Stenger shows that the issue is not philosophical but scientific and that order can and does happen every day - by chance.
