## SIDELIGHTS:

Paul J. Nahin is an electrical engineer whose wide-ranging interests include physics and mathematics of noncausal systems, history of mathematics, technology and science, and the philosophy of science. He is also a writer of science-fiction short stories and several books focusing on mathematics and science. In an interview on the *Powells.com* Web site, the author noted that he enjoyed all aspects of writing, especially the research. When asked to name his favorite book as a child, he replied: "That's easy—*The Time Machine* by H.G. Wells. The final passage is, I think, one of the most romantic, moving passages in the English language. It was certainly the inspiration behind one of my earlier science books … *Time Machines: Time Travel in Physics, Metaphysics, and Science Fiction.*"

In his book *An Imaginary Tale: The Story of the Square Root of Minus One,* Nahin provides an historical examination of this essential equation in mathematics. He discusses the number's use in the past and today and the people who first solved the mathematical equation. *Isis* contributor Ernest Zebrowski, Jr., referred to *An Imaginary Tale* as an "intellectual history of imaginary numbers," adding that the "focus, in fact, is hardly on mathematical manipulation itself, but, rather, on how minds of the past have grappled with the meaning of the curious [square root of-1]." Writing in *Science,* Victor J. Katz noted that "the author tells this story with much grace, wit, and charm." Katz went on to comment that the book "is marvelous reading and hard to put down. Readers will find that Nahin has cleared up many of the mysteries surrounding the use of complex numbers."

*Duelling Idiots and Other Probability Puzzlers* focuses on various mathematical probability problems, such as, what is the chance that first shooter will win in a duel in which each person takes a turn firing one shot. The author presents various problems and then gives their solutions. In a review of *Duelling Idiots and Other Probability Puzzlers,* a *Publishers Weekly* contributor wrote: "Those solutions, in turn, lead readers into neat concepts from higher mathematics." The reviewer went on to comment that the book has "a far better than even chance of fascinating and preoccupying the mathematically literate readership."

Nahin returns to puzzling mathematical problems in *When Least Is Best: How Mathematicians Discovered Many Clever Ways to Make Things As Small (or As Large) As Possible.* Through a series of classical mathematical minimization problems or questions—such as "How can a disoriented person find his or her car in the least amount of time?"—the author discusses geography and algebra beginning on the high school level and then moving onto more complex studies. He also provides a look at the wisdom of ancient mathematicians. Bryce Christensen, writing in *Booklist,* noted that the author "delivers maximal mathematical enjoyment with minimal perplexity and boredom." A *Science News* contributor wrote: "Nahin … has a knack for delving into intriguing mathematics."
