Einstein's "Special Theory of Relativity," first published in 1905, radically changed our understanding of the world. Familiar notions of space and time and energy were turned on their head, and our struggle with Einstein's counterintuitive explanation of these concepts was under way. The task is no easier today than it was a hundred years ago, but in this book Sander Bais has found an original and uniquely effective way to convey the fundamental ideas of Einstein's Special Theory.
Bais's previous book, "The Equations," was widely read and roundly praised for its clear and commonsense explanation of the math in physics. "Very Special Relativity" brings the same accessible approach to Einstein's theory. Using a series of easy-to-follow diagrams and employing only elementary high school geometry, Bais conducts readers through the quirks and quandaries of such fundamental concepts as simultaneity, causality, and time dilation. The diagrams also illustrate the difference between the Newtonian view, in which time was universal, and the Einsteinian, in which the speed of light is universal.
Following Bais's straightforward sequence of simple, commonsense arguments, readers can tinker with the theory and its great paradoxes and, finally, arrive at a truly deep understanding of Einstein's interpretation of space and time. An intellectual journey into the heart of the Special Theory, the book offers an intimate look at the terms and ideas that define our reality.
The elegant illustrations help Bais lead the reader from Einstein's postulates through the ideas of simultaneity, inertial frames, time dilation and relativistic energy and momentum, eschewing the usual admonitions against equations. The author's clever idea of pairing every page of text with a space-time diagram (a graphical tool actually used by relativists) to illustrate the concepts and mathematics suits the geometrical basis of its subject perfectly...It is rare for science books to rate as objects in their own right, but "Very Special Relativity" is a lovely little object. You could easily imagine a web-based version of it, with a bit of animation to serve its pedagogical needs. Still, there is some quality about the hard covers and high resolution that even my 26-inch screen wouldn't be able to capture. No longer is there an excuse for physics textbooks to be expensive, boring, thick or stuffed with equations in order to qualify as good teaching material.--Andrew Jaffe"Nature" (11/01/2007)
