If Only I Had a Brain -- Trying to Understand "Warped Passages"

a book review by Richard Seltzer, seltzer@samizdat.com, www.samizdat.com
about "Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions" by Lisa Randall



On the plus side, this book will expand your understanding of the concept of "dimension".  It also has clear explanations of developments in physics in the days of Einstein and the early stages quantum theory. Above all it gives you a sense of physics as a living, growing, very human endeavor -- a constant challenge, a source of one fascinating puzzle after another, requiring creativity and ingenuity to simply imagine all that might be possible. Half the book deals with theories that have not yet been proved -- fascinating ideas that might turn out to reflect the "real world" but that regardless of that have a puzzle and artistic appeal.

The author is not a reporter or science popularizer, but rather one of the leading theorists. If what she presents is an accurate account of recent developments (and I have no reason to doubt that it is), she deserves a Nobel Prize.

Unfortunately, while she seems to try hard to make her book readable and to make the concepts accessible to the non-professional, the narrative becomes increasingly difficult to follow.  A typical passage from the second half of the book: "This meant, paradoxically, that you could use perturbation theory to study the original strongly interacting, ten-dimensional superstring theory. You would not use perturbation theory in the strongly interacting string theory itself, but in a superficailly entirely different theory: weakly itneracting, eleven-dimensional supergravity. This remarkable result, which Paul Townsend of Cambridge University had perviously also observed, meant that despite their different packaging, at low engergies, ten-dimensional superstring theory and eleven-dimensional supergravity were in fact the same theory.  Or, as physicists would say, they were dual."  What?????

It's like trying to read a book in a language you don't know. Somehow I managed to look at all the words, but I don't feel that I really "read" the book.  And I could probably look at all those words several more times without understanding any more of it.  So I come away impressed at the author's knowledge and accomplishments and creative enthusiasm, but totally frustrated. I simply have no idea what she is talking about. If only I could find a book that unravels the mysteries of this book...
