Book excerpt: Science fiction is all around us; But, which part is science and which is fiction? Have you ever seen a quark, a worm hole, or a neutrino? Heres a few more: UFOs, extra-terrestrials, Big Foot, parallel universes, and black holes. The big questions of life reveal our basic uncertainty: who are we and what are we doing here? How did the universe come into being and where is it headed? These stories are intended to entertain, with a touch of science, history, and humor. My hope is that you enjoy reading these as much as I did their writing.
