The helium which we handle must have been put together at some time and some place. We do not argue with the critic who urges that the stars are not hot enough for this process; we tell him to go and find a hotter place.

There is only one law of Nature-the second law of thermodynamics-which recognises a distinction between past and future more profound than the difference of plus and minus. It stands aloof from all the rest. ...

An electron is no more (and no less) hypothetical than a star. Nowadays we count electrons one by one in a Geiger counter, as we count the stars one by one on a photographic plate.

Schrödinger's wave-mechanics is not a physical theory, but a dodge - and a very good dodge too.

You cannot disturb the tiniest petal of a flower without the troubling of a distant star.

We are bits of stellar matter that got cold by accident, bits of a star gone wrong.
