Book Description
This book covers the present status of art of grand unification with and without supersymmetry (gravity), including cosmological consequences. It is addressed to graduate students and researchers interested in this fastly developing field. But without necessarily any previous experience, however, at least some parts of the book and, in particular, those concerning the most recent developments, are of interest to actively involved researchers in the field.

Book Description
This workshop held at the New England Center provided a timely opportunity for over 100 participants to gather in a unique environment and discuss the present status of the unification of strong and electroweak forces. One reason for the timeliness was perhaps that experiments of the seventies had already lent confirmation to the separate theories of strong and of electroweak forces, so that for the eighties it now seems especially compelling to attempt the grand unification of these two forces. Also, the planned experiments to search for proton decay and the new experiments which are suggestive, though not yet conclusive, of non-zero neutrino rest masses add further stimulus to the theory. Thus, the workshop provided an ideal forum for exchange of ideas amongst active physicists. The presentations at the workshop covered the present status of both theory and experiment with a strong interplay. Also, there were presentations from the discipline of astrophysics which is becoming very intertwined with that of high-energy physics especially when in the latter one is addressing energies and temperatures that were extant only in the first nanosecond of the universe. On experiment, we heard a comprehensive coverage of the four United States proton decay experiments. The Brookhaven-Irvine-Michigan experiment in the Morton Salt Mine at Fairport Harbor, Ohio was discussed by LARRY SULAK, while DAVID WINN talked on the Harvard-Purdue-Wisconsin effort in the Silver King Mine, Utah. MARVIN MARSHAK and RICHARD STEINBERG described respectively the Soudan Mine, Minnesot~ and the Homestake Mine, South Dakot~experiments.

Book Description
It has been sixteen years since the unification of electro Magnetism with the weak interactions was developed by Glashow, Salam, and Weinberg. Well before that proposal was fully confirmed by experiment, work began on unifying strong interactions with the electroweak. Now there is a growing effort to incorporate some theory of quantum gravity into the scheme. This enormous complex of theoreti cal and experimental efforts was the subject of the Fourth Workshop on Grand Unification held in Philadelphia and attended by over two hundred physicists. During the workshop, experimental and theoretical talks alternated as shown by the program summary on page 409. However, to display the logical scope of the workshop the proceedings are organized into five subject areas. Howard Georgi opened the workshop with a keynote address in which he reminds us of some of the simple properties of the particle spectrum that have not yet been understood. The first subject area, and also the largest, is proton decay and underground physics. This is introduced by ~Jill iam r1arciano' s review of the SU(5) predictions with particular attention paid to the theoretical uncertainties. Spokesmen for the major underground experiments present current results on proton decay, nn oscillations, and magnetic monopole flux: B. V. Sreekantan for the Kolar gold field experiment after 1. 9 years of operation, Earl Peterson for the Soudan detector after 0. 55 years, and Bruce Cortez for the rr'lB detector after 0. 22 years.

Book Description
This workshop held at the University of North Carolina was in the series which started with meetings in the University of New Hampshire (April 1980) and the University of Michigan (April 1981). More than one hundred participants congregated in the Carolina Inn in April 1982 to discuss the status of grand unified theories and their connection to experiment. The spring foliage of Chapel Hill provided a beautiful back-drop to this Third Workshop on Grand Unification. As mentioned in the first talk herein, these three workshops have heard of indications, respectively, of neutrino oscillations, proton decay and a magnetic monopole. Since all three experimental reports remain unconfirmed, grand unifiers must wait expectantly and patiently. These proceedings preserve faithfully the ordering of the workshop talks which followed the tradition of alternation between theory and experiment. Only our introduction will segregate them. The experimental presentations mainly concerned proton decay and massive neutrinos. Four U.S. proton decay experiments were reported: the Brookhaven Irvine-Michigan experiment in the Morton Salt Mine at Fairport Harbor, Ohio was described by WILLIAM KROPP, and ROBERT MORSE represented the Harvard-Purdue-Wisconsin group in the Silver King Mine, Utah. The Homestake Mine, South Dakota and Soudan Mine, Minnesota, experiments were reported respectively by RICHARD STEINBERG and DAVID AYRES, the latter providing also a survey of future U.S. experiments.

Book Description
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. Covering time, space, matter, life, and consciousness, Krauss introduces readers to topics that will shape the state of science for the next century, providing us all passport to our own journeys of exploration and discovery.

Book Description
Recent experimental results with direct bearing on theories of cosmological dark matter/energy, as well as continuing work on neutrino masses and mixing, have invigorated both particle physics and cosmology, and should continue to do so well into the 21st century, thereby launching a beautiful new epoch for these fields. The expert contributions from this conference took stock of these developments. This volume contains papers by over 40 physicists that summarize and interpret the newest findings, and suggest future avenues to be explored. A number of new theoretical ideas are also presented, dealing with progress in understanding the dynamics and symmetries of strings and branes, renormalization in quantum field theory, possible Lorentz violation effects, and related problems. Ongoing and next generation gravitational and neutrino experiments are described, and the issues of unification are dealt with in the context of, and beyond, the standard model. Together, the contributions provide a useful blend of experimental and theoretical physics from many prominent physicists, including three Nobel Laureates. The volume also contains information of an historical nature, concerning the contributions to physics by Paul Frampton, on the occasion of his 60th year, and summarizing the career of Behram Kursunoglu (1922-2003).

Book Description
We are now closer than ever to the fundamental goal of physics of understanding all physical phenomena as the inevitable consequences of few simple principles. The grand unified theory of the strong, weak and electromagnetic interactions has, among other things, explained the quantization of charge, determined the magnitude of the neutral current, and had dramatic impact on cosmology. This book is designed to bring interested students and researchers rapidly up to the point where they can contribute to this exciting field. A substantial text provides a review of the subject. In particular, several chapters are devoted to cosmology and the theory of galaxy formation. A selection of original papers is reprinted. A brief review of group theory is also provided. It is a must for all students and researchers in the field.
