Quotes from famous physicists which answer the question "what is physics?"
I am looking for quotes from famous physicists that give a good characterization of "what is physics".
Asking google and chatgpt didn't help so far. In particular chatgpt seemed to "invent" some quotes that actually doesn't exist. For example chatgpt suggested:
"Physics is the most exact, logical, and comprehensive method of arranging the thoughts about the nature that exists." **Reference**: Einstein, A. (1949). *"Autobiographical Notes"*, in P. A. Schilpp (Ed.), *Albert Einstein: Philosopher-Scientist*. Open Court Publishing.
"Physics is the attempt to understand and mathematically describe the natural laws." **Reference**: Newton, I. (1687). *Philosophiæ Naturalis Principia Mathematica*. Royal Society.
However I wasn't able to verify those quotes. #science
