Arthur C. Clarke: The limits of the possible
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Sir Arthur Charles Clarke, CBE, FRAS (16 December 1917 – 19 March 2008) was a British science fiction writer, science writer and futurist, inventor, undersea explorer, and television series host.
He is perhaps most famous for being co-writer of the screenplay for the movie 2001: A Space Odyssey, widely considered to be one of the most influential films of all time. His other science fiction writings earned him a number of Hugo and Nebula awards, which along with a large readership made him one of the towering figures of science fiction. For many years Clarke, Robert Heinlein and Isaac Asimov were known as the "Big Three" of science fiction.
