Arthur C. Clarke Dies at 90

A titan in the field of science fiction:

Co-author with Stanley Kubrick of Kubrick’s film “2001: A Space Odyssey,” Clarke was regarded as far more than a science fiction writer.

He was credited with the concept of communications satellites in 1945, decades before they became a reality. Geosynchronous orbits, which keep satellites in a fixed position relative to the ground, are called Clarke orbits.
