All time great science fiction writer Sir Arthur C Clarke, author of more than 100 books, has died today in Sri Lanka at the age of 90 after a cardio-respiratory attack. Born in 1917 in England, Arthur C Clarke had lived in Sri Lanka for more than half a century. He came to popular fame in 1968 when the short story The Sentinel was made into the film 2001: A Space Odyssey by director Stanley Kubrick. However he made his first mark on this world during World War II when he published a visionary paper detailing the conditions of placing a satellite in geostationary orbit. He was paid about 20 dollars for the theory that launched a multi billion dollar industry.
