Hiding in the Mirror

September 5, 2005
There are few scientific ideas as captivating as the notion that our universe might have other dimensions than the three (plus time) that we experience. Physicist Krauss offers an erudite and well-crafted overview of the role multiple dimensions have played in the history of physics. This isn't an easy book, even with a writer as talented as Krauss (whom some will recognize as the author of The Physics of Star Trek
and Beyond Star Trek
) serving as one's Virgil. Long on science and short on its connections with culture, the book is essentially an introduction to the physics and mathematics of extra dimensions with a few more or less disconnected chapters that touch on how these ideas show up in art and popular culture; there's more on brane-world and the ekpyrotic universe than on Plato's cave, whose inhabitants could not perceive reality in all its dimensions, or Buckaroo Banzai. Those who are willing to put in the requisite effort will be amply rewarded with a unique and impressive survey of scientists' astonishing and evolving understanding of the nature of the universe in all its visible and hidden dimensions.
