Science-fiction impresario Arthur C. Clarke died Tuesday at the age of 90. Best known for 2001: A Space Odyssey, Clarke wrote dozens of fiction and nonfiction books and was instrumental in the earliest thinking about telecommunications satellites. In his later years, he moved to Sri Lanka and helped fight for lowland gorillas, whose territory was threatened by hunters looking for a material used to make cell phones.
