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,warpedgeometry, & 3D sink-holes. We understand far more about the world than we did just a few short years ago -- & 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 Randallis herself making these extraordinary breakthroughs, pushing back the boundaries of science in her research to answer some of the most fundamental questions posed byNature. 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.Randalltakes us into the incredible world ofwarped, hidden dimensions that underpinthe universewe live in, describing how we might prove their existence, while examining the questions that they still leave unanswered.Warped Passagesprovides an exhilarating overview that tracks the arc of discovery from early 20th-century physics to the razor's edge of today's particle physics & string theory, unweaving the current debates about relativity, quantum mechanics, & gravity.In a highly readable style sure to entertain & elucidate,Lisa Randalldemystifies the science & beguilingly unravels the mysteries of the myriad worlds that may exist just beyond the one we are only now beginning to know.Lisa Randallstudies theoretical particle physics & cosmology @ Harvard.
