Space is curved. And time is part of space. And space and time contract as you speed up. Moreover, nothing can go faster than light. Nothing gets out of a black hole. "Acceleration and gravity [are] intimately related." These and other counterintuitive properties of our (expanding) universe all emerged from Einstein's theories of special and general relativity. Their consequences reshaped the world of physicsAand their complexity has given generations of popularizers plenty of work. The latest book to tackle Einstein's insights and their consequences is also one of the clearest and shortest yet. Parker (Search for a Supertheory, etc.), a longtime professor of physics at Idaho State University, explains Einstein's theories in nonmathematical language, along with their famous predictions, tests and implications. A particularly strong chapter (with a full complement of clean diagrams) addresses the theory and practice of time travel. Parker looks with a friendly eye at the private lives of Einstein and his physicist contemporaries (his first chapter covers "Einstein as a Youth"). But he devotes more space to the life of the universeAto its initial big bang and to its probable, gradual end. Starting with the 1887 Michelson-Morley experiment (which proved the nonexistence of an invisible, omnipresent stuff called ether), Parker addresses the findings that moved Einstein to his discoveries. Later chapters outline relativity's successors in the march of theoretical physics, notably quantum theory and Heisenberg's principle of uncertainty, which Einstein himself refused to accept. Students and others looking for fascinating and painless introductions to this particular, well-traveled, but still-startling corner of the sciences will be happy with Parker as their guide. (Sept.)

For an easy introduction to Albert Einstein, the standard is Joseph Schwartz and Michael McGuinness's Einstein for Beginners (1990), a cartoon classic with a Socialist slant. Parker, a former physics professor and prolific science writer (Alien Life: The Search for Extraterrestrials and Beyond), tries his hand at making Einstein's theories accessible to a general audience but falls short of the best efforts in this area. Perhaps the main flaw is that he studiously avoids mention of politics or the atomic bomb yet still tries to take his reader beyond just the science of relativity. The result seems watered down. Parker describes how "hundreds of reporters were soon besieging" Einstein after the confirmation of his theory of relativity, but the reader is left unsure why an unknown physics professor with a theory nobody understood became an overnight celebrity. Parker's scientific writing is nicely done, but the oversimplified diagrams don't help clarify a complex subject. Readers looking for a good introduction should stick to the cartoon or try Denis Brian's fine biography, Einstein: A Life (LJ 4/15/96).AAmy Brunvand, Univ. of Utah, Marriott Lib., Salt Lake City
