During one of his famous Feynman Lectures, Feynman said:
I’d like to address those computer scientists and engineers who remain skeptical that quantum mechanics might be relevant to computers and computation. Nature is not classical, dammit! It’s quantum mechanical. Resistance to quantum mechanics is futile; you will be assimilated.
A great blog needs good quotes.
Okay, I made that Lipton story up too. Oh well. The Feynman photo is authentic though. (Both parts of it.)
