When we measure something we are forcing an undetermined, undefined world to assume an experimental value. We are not measuring the world, we are creating it.
Niels BohrThere are two sorts of truth: trivialities, where opposites are clearly absurd, and profound truths, recognised by the fact that the opposite is also a profound truth
Niels BohrYou can recognize a small truth because its opposite is a falsehood. The opposite of a great truth is another truth.
