If we ask, for instance, whether the position of the electron remains the same, we must say 'no'; if we ask whether the electron's position changes with time, we must say 'no'; if we ask whether the electron is at rest, we must say 'no'; if we ask whether it is in motion, we must say 'no'.

The powerful notion of entropy, which comes from a very special branch of physics … is certainly useful in the study of communication and quite helpful when applied in the theory of language.

There is something irreversible about acquiring knowledge; and the simulation of the search for it differs in a most profound way from the reality.

When you see something that is technically sweet, you go ahead and do it and you argue about what to do about it only after you have had your technical success. That is the way it was with the atomic bomb.

But when you come right down to it the reason that we did this job is because it was an organic necessity. If you are a scientist you cannot stop such a thing. If you are a scientist you believe that it is good to find out how the world works; that it is good to find out what the realities are; that it is good to turn over to mankind at large the greatest possible power to control the world and to deal with it according to its lights and values.

When we deny the EVIL within ourselves, we dehumanize ourselves, and we deprive ourselves not only of our own destiny but of any possibility of dealing with the EVIL of others.

Now I am become death, the destroyer of worlds. (quoting the Bhagavad-Gita after witnessing the first Nuclear explosion.)
