Paul Dirac Quotes

There is a close analogy between organic chemistry in its relation to biochemistry and pure mathematics in its relation to physics.

I am not enough of a mathematician to be able to judge either the well-foundedness or the limits of relativity in physics.

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness.

Physics is based on the assumption that certain fundamental features of nature are constant.

It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom's way of knowing about atoms.

The universe is governed by science. But science tells us that we can't solve the equations, directly in the abstract.

What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.

There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end.

There are 15 main theories in physics, and we know all of them. If there weren't a finite number of theories, there would not be a point to physics.

But even physics cannot be defined from an atomic topography.

Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It's really counterintuitive.

No inanimate object is ever fully determined by the laws of physics and chemistry.

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.

Your chemistry high school teacher lied to you when they told you that there was such a thing as a vacuum, that you could take space and move every particle out of it.

There is nothing new to be discovered in physics now, All that remains is more and more precise measurement

I do not want chemistry to degenerate into a religion; I do not want the chemist to believe in the existence of atoms as the Christian believes in the existence of Christ in the communion wafer.

It seems to be one of the fundamental features of nature that fundamental physical laws are described in terms of a mathematical theory of great beauty and power, needing quite a high standard of mathematics for one to understand it.

It seemed, indeed, that the study of light-scattering might carry one into the deepest problems of physics and chemistry, and it was this belief which led to the subject becoming the main theme of our activities at Calcutta from that time onwards.

The biggest conceptual change over the last 100 years in the way physicists think about the world is symmetry.

Chemistry seems to be pretty much nailed down, and biology gains ground all the time. But physics seems to be mired in idle rumination. They think a Big Bang started the universe, but they don't really know.

I'm a science geek. I even have a T-shirt with a glow-in-the-dark chart of the periodic elements.

There's branches of science which I don't understand; for example, physics. It could be said, I suppose, that I have faith that physicists understand it better than I do.

I thought I should study physics because it's fundamental to all science.

The amount of subtle and beautiful physics that's necessary to make a smartphone work is enormous.

The upshot of all this is that we live in a universe whose age we can't quite compute, surrounded by stars whose distances we don't altogether know, filled with matter we can't identify, operating in conformance with physical laws whose properties we don’t truly understand.
