Kenneth G. Wilson

“The computer has become an indispensable tool for the theoretical physicist.”

“All I had to do was to get the computer to do the work. The problem was that the computer was as obstinate as any human being.”

“The essence of the renormalization group is to integrate out the degrees of freedom that you don't care about.”

“It's much more important to know what questions to ask than it is to know the answers.”

“The problem is not to find the answer, it's to find the right question.”

“My work on the renormalization group was a byproduct of my attempts to understand strong interactions.”

“What is the problem is that we have a theory of the strong interactions which is not calculable.”

“Progress in science is made by asking the right questions, and the questions are often more important than the answers.”

“One must be prepared for the fact that the path to a solution can be very tortuous.”
