Drawing on work by scientists, mathematicians, artists, and writers-from Einstein to Picasso to C. S. Lewis-Hiding in the Mirror explores whether extra dimensions simply represent abstract speculation or hold the key to a deeper understanding of the universe. Krauss examines popular culture's embrace-and misunderstanding-of topics such as black holes, life in another dimension, string theory, and some of the daring new theories that propose that large extra dimensions exist alongside our own. This is popular science writing at its best and most illuminating-witty, fascinating, and controversial.
