Vacuums, Voids, and the Latest Ideas about the Origins of the Universe
March 5, 2001
Nothing's conceptual origins were fraught with fear and disbelief, and only three civilizations independently discovered it. How Nothing went from a Babylonian place holder, a Mayan decoration in the empty space where no number fell and an Indian dot signifying all the current aspects of zero, to one of the most essential elements in mathematics, physics and cosmology, is the subject of this enlightening history. Barrow, a Cambridge professor of mathematical sciences and author of Theories of Everything
and other books, follows Nothing's evolution in a clear, well-organized narrative. It is specific but neither confusing nor at any point slow, and while its more difficult scientific content will cause it to appeal less to general readers than K.C. Cole's The Hole in the Universe
(Forecasts, Jan. 22), there are still plenty of tidbits and trivia that readers will want to share. For, as Barrow demonstrates, pondering the zero can lead to strange discoveries. Two adjacent ships on a calm sea with a brewing swell can be pulled together by a mysterious force similar to that pulling two plates together in a vacuum. Also, we keep time in units of 60 because it was the second base (along with 10) that the Sumerians used in counting. Nothing informs infinite aspects of life and the world at large, and Barrows does an excellent job of bringing its effects to light; plentiful illustrations clarify concepts and bring them into focus. (Apr.)Forecast:While this may appeal less to general readers than Cole's book, science aficionados will greatly enjoy the insights, the detail and the calculations.
