To not know math is a severe limitation to understanding the world.

If you know that you are not sure, you have a chance to improve the situation. I want to demand this freedom for future generations.

Observation, reason, and experiment make up what we call the scientific method.

The "paradox" is only a conflict between reality and your feeling of what reality "ought to be."

The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?

Philosophers say a great deal about what is absolutely necessary for science, and it is always, so far as one can see, rather naive, and probably wrong.
