Product Description
This volume contains papers presented at the Nuffield Workshop on supersymmetry and its applications held at Cambridge in the summer of 1985 and attended by many of the leading experts in the field. In physical terms, supersymmetry is a symmetry or gauge invariance which connects bosons (particles with integer spin) with fermions (particles with half integer spin). The study of supersymmetry has led to the construction of Yang-Mills theories, which are the first field theories to be free of the divergences that usually occur in quantum theories, with an infinite number of degrees of freedom. It has also led to the construction of supergravity and superstring theories which seem to be the best hope for a complete unified theory of all physical interactions including gravity. Supersymmetry and its Applications reviews a number of recent advances in the area of anomalies, the topology of gauge theories, superstrings, supergravity and super Yang-Mills theory.The papers, written by both physicists and mathematicians, include both expository articles and progress reports describing most recent developments. ...

Product Description
Roger Penrose's original and provocative ideas about the large-scale physics of the Universe, the small-scale world of quantum physics and the physics of the mind have been the subject of controversy and discussion. These ideas were set forth in his best-selling books The Emperor's New Mind and Shadows of the Mind. In this book, he summarises and brings up to date his current thinking in these complex areas. He presents a masterful summary of those areas of physics in which he feels there are major unsolved problems. Through this, he introduces radically new concepts which he believes will be fruitful in understanding the workings of the brain and the nature of the human mind. These ideas are then challenged by three distinguished experts from different backgrounds - Abner Shimony and Nancy Cartwright as Philosophers of Science and Stephen Hawking as a Theoretical Physicist and Cosmologist. Finally, Roger Penrose responds to their thought-provoking criticisms. This volume provides an accessible, illuminating and stimulating introduction to Roger Penrose's vision of theoretical physics for the 21st Century. His enthusiasm, insight and good humour shine through this brilliant account of the problems of modern physics. ... Read more

Very good, but some of the selections are a bit dated
This book contains 97 essays written by the giants of 20th century physics and mathematics.These include essays by Einstein, Planck, Bohr, Dirac, von Neumann, Feynman, Hawking, Penrose and Bertrand Russell.Almost all are non-mathematical, but a few (for instance, the essay by Dirac) do require some mathematical expertise.The essays are, on the whole, quite good.My only reservation is that many of the selections are quite dated.This is to be expected, since many of the authors are deceased, and some have been dead for a half-century or more.Furthermore, being compiled in 1989 (the publication date for the original hard cover edition) even the essays by living authors, such as Hawking and Penrose, are somewhat obsolete, hence I can only give this book four-stars.However, even if they do not reflect the most up-to-date understanding of the subject matter that they cover, they are still well worth reading.

Scientists at their best, explaining science to the public
Two of the worlds' most odious clichés relate to the scientific elite and are unfortunately often perpetrated by non-scientific academics. The first is that scientists crawl into an artificial environment and create monstrous things without regard to the consequences. The second is that the scientific upper-echelon finds it impossible to "lower" themselves to the level of everyone else. This collection of over 90 essays, written by the prime scientists of the 19th and 20th centuries, demolishes those beliefs.
The pioneers of modern understanding have often been the vanguard of those trying to educate the public about what the newest scientific discoveries really mean. And scientists have always written for the masses, such as they were. Even Kepler and Galileo wrote popular works to explain their positions.
The material in this book represents scientists at their best. You read of joy, anguish, fulfillment, shock, puzzlement, success and failure. In short, you read about humans experiencing the world. The level of difficulty is very low, suitable for high school on up.
Showing scientists at their human best, this book will convince all but the stone-minded that scientists really are at home in the world.

He could have had a V8
In a set of articles by great men that could have been worthwhile
we have a failure. I know because I have something real to compare this to
as contrastSource Book in Mathematics. What results is very like "The End of Science: Facing the Limits of Knowledge in the Twilight of the Scientific Age" in content.
What we have here is an anti-mathematics thesis with only vague points
to the real stuff.What results is a dumbed down collection that is really unworthy of the author.
Praising this book is like praising vanilla pudding!
Without the whipped cream of the mathematics the pudding is
limp and colorless. What we really need is a true source book
with the real material in it.
The closest I've seen is Roger Penrose's"The Road to Reality: A Complete Guide to the Laws of the Universe".
In dumbing it down there is no protection against science and the mathematics
that makes it work .

Excellent
An excellent book to read on science and mathematic related ideas. It's easy to understand and fun to read. It doesn't only stop at the scientists' and mathematicians' lives and their work. Read it and find out... More!
