You peaked too soon.
My perception is that Asimov was much more of a talker and explainer than a "doer". He earned a Ph.D. in biochemistry, but I have never heard anything about research he did himself, or advances to science that he made. I would be interested to learn otherwise if anyone here knows. Not that explaining and popularizing is a bad thing. Some of my graduate school professors, who were considered good researchers, were so bad at lectures that I bought Asimov's books to make sense of the lecture notes. There is a difference between explaining and discovering new information and I wonder what Asimov's capabilities were in the latter.
Asimov is a brilliant science fiction writer. And it seems he's done it again.
