Arthur C. Clarke, a visionary science fiction writer who co-wrote "2001: A Space Odyssey" and won worldwide acclaim with more than 100 books on space, science and the future, died Wednesday, an aide said. He was 90.
Clarke, who had battled debilitating post-polio syndrome since the 1960s, died at 1:30 a.m. in his adopted home of Sri Lanka after suffering breathing problems, aide Rohan De Silva said.
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.
Any sufficiently advanced technology is indistinguishable from magic.
