One of the ways of stopping science would be only to do experiments in the region where you know the law. But experimenters search most diligently, and with the greatest effort, in exactly those places where it seems most likely that we can prove our theories wrong. In other words, we are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.

There is no authority who decides what is a good idea.

Phenomena complex-laws simple....Know what to leave out.

[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd.

There is no learning without having to pose a question. And a question requires doubt.

Outside of their particular area of expertise scientists are just as dumb as the next person.

A scientist is never certain. ... We absolutely must leave room for doubt or there is no progress and there is no learning.
