PHILOSOPHY COLLOQUIUM ANNOUNCEMENT: COMPUTERS ARE NOT OMNIPOTENT David Harel Weizmann Institute and Carnegie Mellon University Monday, October 6 4:00 p.m. Porter Hall 223D In April, 1984, TIME magazine quoted a computer professional as saying: "Put the right kind of sofware into a computer and it will do whatever you want it to. There may be limits on what you can do with the machines themselves, but there are no limits on what you can do with the software." In the talk we shall disprove this contention outright, by exhibiting a wide array of results obtained by mathematicians and computer scientists between 1935 and 1983. Since the results point to inherent limitations of any kind of computing device, even with unlimited resources, they appear to have interesting philosophical implications concerning our own limitations as entities with finite mass.
