If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly. (Richard Feynman)

You know?

It is time to return to those core values, time to get back to basics: to self-discipline and respect for the law, to consideration for others, to accepting responsibility for yourself and your family, and not shuffling it off on other people and the state.

Opinion is like a pendulum and obeys the same law. If it goes past the centre of gravity on one side, it must go a like distance on the other; and it is only after a certain time that it finds the true point at which it can remain at rest.
