Then you'll be glad to know that he's written an astounding number of short stories - you have good times ahead finding them all :-)
Yeah the only books of his I have read are the Foundation series...kept meaning to dig more into his works. I think I will now :)
Really love the short story where he takes you through the first ever trillionth frame per second imaging of an atomic explosion!
The one where the historian builds a "past window" device and releases the specification on the internet really makes me think, too....
Do you remember what those are called? I don't remember reading either book, and I've read quite a lot of his writings.
