To the confusion of our enemies.

It is a profound and necessary truth that the deep things in science are not found because they are useful: they are found because it was possible to find them.

The peoples of this world must unite or they will perish.

I am become Death, the destroyer of worlds.
N.B.: This is a paraphrase from the ancient Hindu text, the Bhagavad Gita.

Any man whose errors take ten years to correct is quite a man.

If the radiance of a thousand suns
Were to burst at once into the sky
That would be like the splendour of the Mighty One...
I am become Death,
The shatterer of worlds.

[Quoted from the Bhagavad Gita after the bombing of Hiroshima and Nagasaki.]
