The overlap between physics and math degrees is generally considered to be less than 50%. Both disciplines share foundational lower division math courses, including linear algebra, multivariable calculus, and differential equations. However, upper division courses diverge significantly; pure math focuses on proofs and abstract concepts, while physics emphasizes practical applications of mathematical tools for calculations. Proficiency or interest in one field does not necessarily translate to the other, as they require distinct skill sets and thought processes. While it is possible to excel in both areas, the teaching style of professors can influence this experience. For students pursuing a double major, additional math classes are typically required, potentially extending their studies by a year.
