Mathematics is the cheapest science. Unlike physics or chemistry, it does not require any expensive equipment. All one needs for mathematics is a pencil and paper.

We have sought for firm ground and found none. The deeper we penetrate, the more restless becomes the universe; all is rushing about and vibrating in a wild dance.

What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.

Sometimes I wonder if my heart is like a black hole--it's so dense that there's no room for light, but that doesn't mean it can't still suck me in.

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.

An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.

The particles that are the very building blocks of all things, are in all possible locations until observation/measurement causes them to choose a specific position.

If you can't illustrate 'it', 'it' doens't belong in Physics as a noun! You can't put an article in front. You can't put a verb after!

Physics is mathematical not because we know so much about the physical world, but because we know so little; it is only its mathematical properties that we can discover.

Asked in 1919 whether it was true that only three people in the world understood the theory of general relativity, [Eddington] allegedly replied: 'Who's the third?

Some string theorists prefer to believe that string theory is too arcane to be understood by human beings, rather than consider the possibility that it might just be wrong.

Stay upbeat and keep your head held high. There is no end to the power of positive thinking. I AM looking forward to all the wealth, success, and abundance speeding my way!

There are reasons to doubt that what we call the laws of physics necessarily apply everywhere in the universe—or that they were applicable to every time in its history.

There are many people who say there's a God somewhere up there but, God is nothing more than a formula. Just a part of some law of physics that we have yet to understand.

The history of atomism is one of reductionism – the effort to reduce all the operations of nature to a small number of laws governing a small number of primordial objects.
