Paul Nahin was born in California, and did all of 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 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.

Prof. Nahin has published a couple of dozen short science fiction stories in ANALOG, OMNI, and TWILIGHT ZONE magazines, and has written 14 books on mathematics and physics. 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 scriptfor their time travel episode. He gave the invited Sampson Lectures for 2011 in Mathematics at Bates College (Lewiston, Maine).

By the author of the popular books "Time Machines" and "The Science of Radio"

Discusses the opinions and writings of philosophers and scientists (Pascal, Hume, Nietzsche) and science fiction authors (Arthur C. Clark, C. S. Lewis, Isaac Asimov)

Draws connections between science fact, science fiction, philosophy, and theological debate over the past five centuries
