- Physics can't even prove physics.
- ...it was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.
- "OK, so the computer has understood, but what about me?" -- allegedly Wigner on numerical simulations.
The original quote seems to be "It is nice to know that the computer understands the problem, but I would like to understand the problem, too."

P. Wigner: "It is nice to know that the computer understands the problem. But I would like to understand it, too".
