Jesus. I'm Arthur C Clarke

Which is something of a surprise, you have to admit. All those years I never knew.
Though I did read quite a lot of him when I was a kid.
See below.

Off now to see a plastic surgeon. Second time in my life I've been told "there is a million to one chance that you have cancer". So, realistically I've only got 999, 998 chances left. Trouble is that I have read my Pratchett, and therefore know that million to one shots work nine times out of ten. It's the narrativium.

I am: Arthur C. Clarke Well known for nonfiction science writing and for early promotion of the effort toward space travel, his fiction was often grand and visionary.

Which science fiction writer are you?
