= Theory or experiment = Which activity is more fundamental in physics/science? A. '''Theoretical activity''', like constructing a bold and beautiful theory to explain what has been observed and predict new phenomena. A. '''Experimental activity''', like discovering phenomena that no theory can yet explain or measuring fundamental constants to very high accuracy. Ans: Follow your heart. But, keep in mind that physics is an experimental science. = The fundamental of experiment = Which of the following is the most fundamental principle of physics experiment? A. An experiment must be reproducible. A. An experiment must conform to well-established theories. A. An experiment must produce striking results and attract lots of publicity. Ans: A = The fundamental of theory = Which of the following is the most fundamental theoretical principle of modern physics? A. String theory. A. Schrodinger's equation. A. Newton's equation. A. Symmetry and conservation principle. Ans: D, as far as we know so far. (Typo correction!) = The origin of the symmetry principle = The well-established symmetry principles in physics A. are fundamentally tied to the reproducibility of experiments, the most fundamental operating principle of science/physics. A. are in essence nothing but a belief system that makes science/physics a pseudo-religion at the bottom of it. A. often started as bold conjectures. A. are those that you can verify/refute based on your experimentation. Ans: A, C, D.
