One of the giants of science fiction has passed on. His writing was always somewhat dry in my view and to be honest he didn't really do characters but God some of the ideas. Harks back to when the bulk of science fiction came from the pens of actually science grounded people, like scientists and engineers, like Asimov, Heinlein and Clarke . I think his short stories are today somewhat under appreciated though that is where 2001 came from.
While his idea or promote of geo stationary satellites will doubtless get lots of attention over the coming days I think the his use of the idea of the space elevator may end up being the more significant in terms of the exploration of space by humans.
