"Nothing in life is certain except death, taxes and the second law of thermodynamics. All three are processes in which useful or accessible forms of some quantity, such as energy or money, are transformed into useless, inaccessible forms of the same quantity. That is not to say that these three processes dont have fringe benefits: taxes pay for roads and schools; the second law of thermodynamics drives cars, computers and metabolism; and death, at the very least, opens up tenured faculty positions."

"Of course, one way of thinking about all of life and civilization is as being about how the world registers and processes information. Certainly thats what sex is about; thats what history is about."

"Quantum mechanics is weird. I dont understand it. Just live with it. You dont have to understand the nature of things in order to build cool devices…If you can figure out how to take advantage of this quantum multitasking, we can build computers that can do computations that no classical computer could do even if it were the size of the entire universe."
