Another great one gone

Arthur C. Clarke died yesterday in Sri Lanka.
In a videotaped 90th birthday message to fans, Clarke said he still hoped to see some sign of intelligent life beyond Earth, more work on alternatives to fossil fuels -- and "closer to home," an end to the 25-year civil war in Sri Lanka between the government and ethnic Tamil separatists. He is widely credited with introducing the idea of the communications satellite, the first of which were launched in the early 1960s. But he never patented the idea, prompting a 1965 essay that he subtitled, "How I Lost a Billion Dollars in My Spare Time".
