Wow! Warped Passages is for serious amateurs with an interest in esoteric science. At one time, I read a lot more of this stuff than I do now, so I will admit to being a little rusty. The interview I heard on NPR mentioned string theory, which I find endlessly fascinating, if not entirely understandable. Randall’s fluid prose added to my knowledge there, but I was lost when she started talking about “branes.” She defines these as “A membrane-like object in higher-dimensional space that can carry energy and confine particles and forces” (460). This gives you some idea of what I was up against. Still I slogged on, and I am glad I did. Branes are an extension of string theory, and the idea is that they hold the key to extra dimensions in space. Maybe all those UFOs have found a way to pass between branes and enter our plane of existence. I know I will come back to this book in the future, because it makes an excellent reference work. A handy glossary and summaries at the end of each chapter are extremely helpful. Her line drawings were also good for illustrating some of her ideas. Four gold stars! --Jim, 7/17/08 (  ) rmckeown | Jul 17, 2008 | Absolutely wonderful book. Lisa manages to describe without maths what is behind current theories in physics and the workings of the fundamental particles of all matter. She actually makes the unfolding mysteries of quarks and leptons fascinating reading, describing the paths that research has taken in the last 50 years or so and what is left to find out. You won't remember much of the details but what you will get is a general understanding of what they are looking for and how they do it. (  ) caz4562000 | Jun 30, 2008 | Most of this book is really about the modern history of physics, but she eventually gets to the incredibly interesting topics that she currently researches. This is excellent popular science. ( ) wanack | Jun 28, 2008 | This is not an easy book to read. What's easy about quantum mechanics? To my own astonishment, however, Lisa Randall took me from basic physics to the esoteric theories of warp geometry, string theory and added dimensions in a way that I could understand and actually remember. She uses examples from our daily lives in an imaginative and fun way to make the readers understand some extraordinarily difficult concepts and take us along the road of discovery and, of course, speculation. This book has nothing to do with Star Trek or Star Wars but I found it just as fascinating. ( ) mdbenoit | Mar 30, 2008 |  no reviews | add a review

| Book description |
|
The universe has its secrets. It may even hide extra dimensions, different from anything ever imagined. A whole raft of remarkable concepts now rides atop the scientific firmament, including parallel universes, warped geometry, and threedimensional sink-holes. We understand far more about the world than we did just a few short years ago -- and yet we are more uncertain about the true nature of the universe than ever before. Have we reached a point of scientific discovery so advanced that the laws of physics as we know them are simply not sufficient? Will we all soon have to accept explanations that previously remained in the realm of science fiction?
Lisa Randall is herself making these extraordinary breakthroughs, pushing back the boundaries of science in her research to answer some of the most fundamental questions posed by Nature. For example, why is the gravitational field from the entire Earth so defenseless against the small tug of a tiny magnet? Searching for answers to such seemingly irresolvable questions has led physicists to postulate extra dimensions, the presence of which may lead to unimaginable gains in scientific understanding. Randall takes us into the incredible world of warped, hidden dimensions that underpin the universe we live in, describing how we might prove their existence, while examining the questions that they still leave unanswered.
Warped Passages provides an exhilarating overview that tracks the arc of discovery from early twentieth-century physics to the razor's edge of today's particle physics and string theory, unweaving the current debates about relativity, quantum mechanics, and gravity. In a highly readable style sure to entertain and elucidate, Lisa Randall demystifies the science and beguilingly unravels the mysteries of the myriad worlds that may exist just beyond the one we are only now beginning to know.
