Lisa Randall " Warped Passages : Unravelling the Universe's Hidden Dimensions" (Penguin)





Lisa Randall is a theoretical physicist who specializes in the so-called Standard Model of particle physics. She explains the particles and forces depicted in that model, and where the model fails as a picture of the real subatomic world. For example, it does not explain gravity's weakness compared with electromagnetism and the weak and strong nuclear forces. Randall's proposed solutions to the deficiencies in the Standard Model, unlike some of the other propositions of string theory, can be experimentally tested.
Randall writes as clearly as possible, I think; but to follow the text is made much easier if one is already acquainted with some basic principles of theoretical physics.
One awaits eagerly the results of the tests at the LHC (Large Hadron Collider) at CERN, which will or will not support her theories. If she turns out to be right, we will know that there is at least a 5th dimension to our universe and that the 'branes' of String Theory are real.
