Book excerpt: Whether discussing theories of cosmology, the physics of making a violin, or the impact of magazine covers on potential buyers, physicist and writer Tony Rothman brings the worlds of the scientist and nonscientist closer together, with amusing and enlightening results. These essays, which bear the mark of Rothman's outspoken humor and dislike for pretense, convey essential ideas to general readers on such topics as the future of the universe, the design of particle accelerators, the intelligent use of statistics, and the making of quality musical instruments. At the same time they provide insight into how the mind of a scientist works, not only in research but also in the "real" world of three-piece suits and mass media. The outlook of physicists, according to the author, often puts them at odds with nonscientists--but Rothman never hides his points of disagreement. In his title essay on being a major magazine editor, he recalls using bell curves and elementary statistics in an attempt to convince the circulation department that fluctuations in sales are unavoidable (despite what they thought). Although Rothman claims that scientists do enjoy playing the role of Faust, the scholar in eternal pursuit of Truth, his essays attest to a scientific interest fully in tune with human concerns.
