[1] The book describes, at a non-technical level, theoretical models Professor Randall developed with the physicist Raman Sundrum, in which various aspects of particle physics (e.g. supersymmetry) are explained in a higher-dimensional braneworld scenario.

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."

"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."

"[1] Randall is currently a professor at Harvard University in Cambridge, Massachusetts, focusing on particle physics and cosmology.

[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.
