Pick a flower on Earth and you move the farthest star.

I should like to suggest to you that the cause of all the economic troubles is that we have an economic system which tries to maintain an equality of value between two things, which it would be better to recognise from the beginning as of unequal value.

The fundamental laws necessary for the mathematical treatment of a large part of physics and the whole of chemistry are thus completely known, and the difficulty lies only in the fact that application of these laws leads to equations that are too complex to be solved.

There is in my opinion a great similarity between the problems provided by the mysterious behavior of the atom and those provided by the present economic paradoxes confronting the world.

It's not clear in physics why you can't see the future.

I guess the most surprising discovery was how long Gandhi remained loyal to the ideal of the British Empire, even in India.

When I was about 9 years old, I became very interested in the human body and diseases. In general, I was just curious about the world around me. I think that any sort of curiosity as a child is a good beginning to a career in science because science, at least to me, is a continuous exploration of the unknown.

On the second flight, we were doing a lot of science experiments, and we've got a really cool window called the cupola. It's a big, circular window with six panes around, sort of at angles so you can see the Earth, you can see the edge of the Earth, you can go out - look out into the universe. It's pretty spectacular.
