Why physics makes room for redundant descriptions

Gauge Theory and the Geometrisation of Physics examines a central conceptual feature of modern physics: the use of multiple mathematically distinct descriptions connected by gauge symmetry. In a compact format, Henrique de Andrade Gomes frames gauge theory not simply as technical machinery behind the Standard Model, but as a philosophical question about why descriptive redundancy helps scientific models work. The discussion develops three linked responses: a pragmatic or methodological account, a geometrical account, and a broadly relational one. With its emphasis on explanation and conceptual foundations, the book places gauge theories within the larger project of understanding how geometry informs physical description.

Good fit for readers who enjoy

Book overview

This Element is broadly about the geometrization of physics, but mostly it is about gauge theories. Gauge theories lie at the heart of modern physics: in particular, they constitute the Standard Model of particle physics. At its simplest, the idea of gauge is that nature is best described using a descriptively redundant language; the different descriptions are said to be related by a gauge symmetry. The over-arching question this Element aims to answer is: why is descriptive redundancy fruitful for physics? I will provide three inter-related answers to the question: Why gauge theory?'', that is: why introduce redundancies in our models of nature in the first place? The first is pragmatic, or methodological; the second is based on geometrical considerations, and the third is broadly relational.
