In physics, the symbol ~ can have multiple meanings, depending on the context. It’s often used to indicate an approximate value or quantity.
Mathematical physics is the application of mathematics to problems in physics. It focuses on tools and techniques physicists use, applying mathematical concepts to physics problems. Mathematical physics tends to focus on more formal aspects of physics rather than the theoretical, although the mathematical language can be used in both.
