is the science of the natural world
, which deals with the fundamental particles the universe is made of, the interactions
between them, and the interactions of objects composed of them (nuclei, atoms, molecules, etc).
- Physicists use the wave theory on Mondays, Wednesdays and Fridays and the particle theory on Tuesdays, Thursdays and Saturdays
- William Henry Bragg; quoted in Dictionary of Scientific Quotations by Alan L. Mackay, Institute of Physics Publishing, Bristol, 1994, p. 37 http://materials.usask.ca/diversions/quotes/
- Variant: On Mondays, Wednesdays and Fridays we teach the wave theory and on Tuesday, Thursdays and Saturdays the corpuscular theory.

- unsourced variant: God runs electromagnetics by wave theory on Monday, Wednesday, and Friday, and the Devil runs them by quantum theory on Tuesday, Thursday, and Saturday. http://www.quotationspage.com/quote/26212.html
- Physics and philosophy are at most a few thousand years old, but probably have lives of thousands of millions of years stretching away in front of them. They are only just beginning to get under way.
- Physics and Philosophy (1942), p.217.
- Our judge is not God or governments, but Nature.
- "If I were forced to sum up in one sentence what the Copenhagen interpretation says to me, it would be 'Shut up and calculate!'"
- All science is either physics or stamp collecting.
- Sir Ernest Rutherford
- Variant: In science there is only physics; all the rest is stamp collecting.
- Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?
- Guests at a cocktail party in the Southern Hemisphere tend to circulate in an anticlockwise direction.
- Corollary to Parkinson's 2nd Law
- I think I can safely say that nobody understands quantum mechanics.
- If [quantum theory] is correct, it signifies the end of physics as a science.
- My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.
- Nothing is more interesting to the true theorist than a fact which directly contradicts a theory generally accepted up to that time, for this is his particular work.
- Physics is like sex. Sure, it may give some practical results, but that's not why we do it.
- The theory of quanta can be likened to medicine that cures the disease but kills the patient.
- Toast always lands buttered-side down, and a cat always lands feet first. I propose we strap buttered toast to the back of a cat; the two will hover, spinning inches from the ground. With a giant buttered-toast/cat array, a hovering monorail could easily link New York with Chicago.
