Albert Einstein
There is not the slightest indication that energy will ever be obtainable from the atom.

The more success the quantum theory has, the sillier it looks.

The Doctoral student Ilse Rosenthal-Schneider asked Einstein in 1919 how he
would have reacted if his general theory of relativity had not been
confirmed experimentally that year by Arthur Eddington and Frank Dyson.
His answer was: "Then I would feel sorry for the good Lord. The theory is
correct anyway."

The Lord God is subtle, but malicious he is not
I have second thoughts. Maybe God *is* malicious

"Some men spend a lifetime in an attempt to comprehend the complexities of
women (or vice versa). Others pre-occupy themselves with somewhat simpler
tasks, such as understanding the theory of relativity !"

Stephen Hawking
"My goal is simple. It is complete understanding of the universe, why it as
it is and why it exists at all."

Scientific discovery may not be better than sex, but the satisfaction lasts
longer

Each equation ... in the book would halve the sales.
