I have a theory that the secret of marital happiness is simple: drink in different pubs to your other half.
Jilly Cooper

Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave nether room nor demand for a theory of probabilities.
George Boole

I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to the extreme smallness of the variations in the period of oscillation.
Pieter Zeeman

Vietnam was a lie but at least there was a political agenda. It was the domino theory. Iraq is about nothing but George Bush's ego laced with imperialist ambitions. And it was helped by your government.
