Paul Preuss recently returned to writing science fiction and fact, and historical fiction about science, after years as a full-time science writer, covering all fields but specializing in physics, cosmology, accelerators, photon science, and, lately, engineering. Previously, as a freelance, he wrote novels (thirteen of them), science articles (scores), book reviews (by the hundreds), and miscellany (uncountable). And before that he made documentary films and worked on network TV specials—his first and shortest professional film was “Over, Through, Around” for the premier episode of Sesame Street. He was a drama major at Yale, where he graduated with honors as a Scholar of the House in film and drama. Preuss’s father was an air force officer, and he grew up in various places, with the longest stay at Sandia Base in New Mexico.
