Where else but Mudcat would one see anon. posters second guessing Stephen Hawking? And calling him cavalier?! I liked Brief History of time as much for the little stories and side notes as for the "science". I felt it gave me an insight into his character that I would not otherwise have had. Obviously, in spite of the objections GUEST liked it enough to read it four times.It probably is time for a sequel. Or at least and update. If so I am sure that Mr. Hawking is technically current enough to write it if he so chooses. IanB were the audiocassettes in Mr. Hawkings computer-generated voice? If so, it must have seems like forever, relatively speaking.
