parsimony as a theoretical virtue alongside

descriptive accuracy\, and aim to minimize the

amount of structure present in mathematical

formalisms used to represent physical systems. I

present a proposal for formalizing structure

comparison in physics using category theory\,

which can be thought of as the mathematical

theory of structure. I show how this method can

be used to compare alternative formulations of

Yang-Mills theory (which underlies modern

particle physics)\, and evaluate claims by

philosophers and physicists regarding their

relative structure.
