Simple CPU
Here Feynman explains the basic logic behind building of all of the computers. He is inspiring even if you know more details about the topics he talks about, because he stimulates you to a fresh view. The youtube title is, IMHO, misleading. The lecture is about the basic hardware concepts and not about heuristics, so I think it fits perfectly with the OP.http://www.youtube.com/watch?v=EKWGGDXe5MAEdit: At the start the original title is visible it's "Richard Feynman: The Computers From the Inside Out" and the lecture is from 1985.The major quote:"Computers are not primarily computing machines, they are actually filing systems."
