Peter Norvig http://www.norvig.com Articles by Peter Norvig en-us Prescient but Not Perfect: A Look Back at a 1966 Scientific American Article on Systems Analysis My thoughts on a 1966 Scientific American article that was my introduction to programming.

I don't know of anything like it in the history of science." This essay argues that it is not novel at all, but perfectly commonplace. http://norvig.com/chomsky.html http://norvig.com/chomsky.html 2011-05-27 Dance Photography An overview of photographic techniques for taking pictures of indoor dance performances.
