I've always been a scifi fan, but stories that cleverly use or abuse the laws of physics are my favorites. My favorite Isaac Asimov short story is "The Billiard Ball." If you haven't read it, do it now. If you have, then maybe you should read it again... I also particularly like David Gerrold ("The Man Who Folded Himself" is excellent), Neal Stephenson ("Snow Crash"), William Gibson ("Neuromancer"), Arthur C. Clarke and Isaac Asimov for SciFi.
