Who will observe the observers?

There was a time when we wanted to be told what an electron is. The question was never answered. No familiar conceptions can be woven around the electron; it belongs to the waiting list.

Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers. If you look at the results which science has brought in its train, you will find them to consist almost wholly in elements of mischief. See how much belongs to the word "Explosion" alone, of which the ancients knew nothing.

The electron, as it leaves the atom, crystallises out of Schrodinger's mist like a genie emerging from his bottle.

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

[When thinking about the new relativity and quantum theories] I have felt a homesickness for the paths of physical science where there are ore or less discernible handrails to keep us from the worst morasses of foolishness.

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