For about 3 years we have every 3rd week read a classic paper in physics, statistics, probability theory, information theory, game theory and computation. So far we have gone through about 40-50 papers and the papers have generally been superb.
Søren Riis (Queen Mary, London) and Jotun Hein gave a talk to summarize 10 of the papers that fall within computation/complexity theory. The papers are Babbage, Turing, McCullough/Pitt, von Neumann, Cook, Karp, Smale, Shor, Impagliazzo, Papadimitriou.
The slides of his presentation are available here
