Stephen Hawking quotes on quantum

33. Maybe that is our mistake: maybe there are no particle positions and velocities, but only waves. It is just that we try to fit the waves to our preconceived ideas of positions and velocities.The resulting mismatch is the cause of the apparent unpredictability.

43. He's a Platonist and I am a positivist. He's worried that Schrodinger's cat is in a quantum state, where it is half dead and half alive. He feels that can't correspond to reality. But that doesn't bother me. I don't demand that a theory correspond to reality because I do not know what it is. Reality is not a quality you can test with litmus paper. All I am concerned with is that the theory should predict the results of measurements. Quantum theory does this very successfully. It predicts that the result of an observation is either that the cat is alive or that it is dead. It is like you can't be slightly pregnant; you either are or you aren't.

58. When I hear of Schrodinger's cat, I reach for my gun.
