What we makes of the world must be largely dependent on the sense-organs that we happen to possess. How the world must have changed since the man came to rely on his eyes rather than his nose.

But it is necessary to insist more strongly than usual that what I am putting before you is a model-the Bohr model atom-because later I shall take you to a profounder level of representation in which the electron instead of being confined to a particular locality is distributed in a sort of probability haze all over the atom.

So far as physics is concerned, time's arrow is a property of entropy alone.

It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.

We often think that when we have completed our study of one we know all about two, because 'two' is 'one and one.' We forget that we still have to make a study of 'and.'

Something unknown is doing we don't know what-that is what our theory amounts to.
