Are There More Than Three Dimensions in the Universe? Unraveling Hidden Mysteries (2005)

Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions is a book by Lisa Randall, published in 2005, about particle physics in general and additional dimensions of space (cf. Kaluza--Klein theory) in particular. The book has made it to top 50 at amazon.com, making it the world's first successful book on theoretical physics by a female author.[citation needed] She herself characterizes the book as being about physics and the multi-dimensional universe.[1]




She comments that her motivation for writing this book was her "thinking that there were people who wanted a more complete and balanced vision of the current state of physics." She has noticed there is a large audience that thinks physics is about the bizarre or exotic. She observes that when people develop an understanding of the science of particle physics and the experiments that produce the science, people get excited. "The upcoming experiments at the Large Hadron Collider (LHC) at CERN near Geneva will test many ideas, including some of the warped extra-dimensional theories I talk about." Another motivation was that she "gambled that there are people who really want to understand the physics and how the many ideas connect."[1]

Randall is currently a professor at Harvard University in Cambridge, Massachusetts. However, she stays active in the field because she continues to study both particle physics and cosmology. She stays current through her research into the nature of matter's most basic elements, and the forces that govern these most basic elements. Randall's experiences, which qualify her as an authority on the subject of the book, are her original "contributions in a wide variety of physics studies, including cosmological inflation, supersymmetry, grand unified theories, and aspects of string theory". "As of last autumn, she was the most cited theoretical physicist in the world during the previous five years." In addition her most recent work involved extra dimensions.[2]



Her background research for the book, on the theories and experiments of extra dimensions and warped geometries, was published in the peer-reviewed Science magazine in 2002[3]

Lisa Randall (born June 18, 1962) is an American theoretical physicist and a leading expert on particle physics and cosmology. She works on several of the competing models of string theory. Her best known contribution to the field is the Randall--Sundrum model, first published in 1999 with Raman Sundrum.[1] Randall-Sundrum theory predictions are subject to ongoing tests at the LHC. [2] However, the experimental signature that would be required to validate the Randall-Sundrum model would be the discovery of a class of particles called Kaluza-Klein particles. This would constitute a monumental discovery in physics. It would be the first physical evidence that superstring theory is on the right track. Given the magnitude of such a discovery, administration at the Large Hadron Collider would undoubtedly hold a press conference to announce such a discovery. Furthermore, the physics literature would thoroughly address this discovery. Since neither of these events has transpired, the following can be safely concluded. To date, the L.H.C has yet to produce any evidence to validate the Randall-Sundrum model at slightly over half of its energy capability. She was the first tenured woman in the Princeton University physics department and the first tenured female theoretical physicist at both MIT and Harvard University. She has also written two popular science books and the libretto of an opera.
