Paul Nahin was born in California, and did all his schooling there (Brea-Olinda High 1958, Stanford BS 1962, Caltech MS 1963, and - as a Howard Hughes Staff Doctoral Fellow - UC/Irvine PhD 1972, with all degrees in electrical engineering). He worked as a digital logic designer and radar systems engineer in the Southern California aerospace industry until 1971, when he started his academic career. He has taught at Harvey Mudd College, the Naval Postgraduate School, and the Universities of New Hampshire (where he is now emeritus professor of electrical engineering) and Virginia. In between and here-and-there he spent a post-doctoral year at the Naval Research Laboratory, and a summer and a year at the Center for Naval Analyses and the Institute for Defense Analyses as a weapon systems analyst, all in Washington, DC. He has published a couple dozen short science fiction stories in ANALOG, OMNI, and TWILIGHT ZONE magazines, and has written 16 books on mathematics and physics, published by IEEE Press, Springer, and the university presses of Johns Hopkins and Princeton. His most recent book, INSIDE INTERESTING INTEGRALS, discussing numerous techniques for doing definite integrals (up through and including contour integration in the complex plane) that commonly occur in physics, engineering, and mathematics, was published by Springer in September 2014. His next book, IN PRAISE OF SIMPLE PHYSICS, on the application in everyday life situations of elementary mathematics (up to and including freshman calculus) and the fundamental physical laws, is under contract with Princeton University Press and will appear May 2016. Another book, TIME MACHINE TALES, an up-dating of the 2nd edition of TIME MACHINES (1999), is under contract at Springer (in the Fiction & Science series) and will appear in 2017. He has given invited talks on mathematics at Bowdoin College, the Claremont Graduate School, the University of Tennessee, and Caltech, has appeared on National Public Radio's "Science Friday" show (discussing time travel) as well as on New Hampshire Public Radio's "The Front Porch" show (discussing imaginary numbers), and advised Boston's WGBH Public Television's "Nova" program on the script for their time travel episode. He gave the invited Sampson Lectures for 2011 in Mathematics at Bates College (Lewiston, Maine).
FINALLY - numerous readers have written over the years asking about the solutions manual to my Springer book, THE SCIENCE OF RADIO. Springer has kindly made it available in pdf format (3 MB), and if you write to me I'll send you a copy. email@example.com
