Symmetry and Physics

Jan 24, 2021   |   25 min read   |   casual

Many articles on physics nowadays mention symmetry—supersymmetry, symmetry breaking, symmetry groups, gauge symmetries, CPT symmetry. The term is truly everywhere. In fact, Nobel Laureate Phil Anderson once remarked, "it is only slightly overstating the case to say that physics is the study of symmetry." For the uninitiated, it is not so obvious what symmetry has to do with physics—however, there are many accessible examples of symmetry at work, perfect for getting a feel for its beautiful ties to the physical world.
