About nLab Physics

nLab Physics is a page on nLab titled "higher category theory and physics." It gathers links and material on mathematical physics and related topics, with a focus on connections between physics and category theory, especially higher category theory. The page is organized as a contents outline and sidebars rather than a standalone article.

The outline covers physics topics such as mechanics, spacetime, relativity, quantum mechanics, quantum field theory, gauge theory, string theory, and structural phenomena. It also links category theory and higher category theory concepts, including functors, adjoint functors, ∞-categories, model categories, and cobordism. Users can follow cross-references to nLab pages, use navigation links, and discuss or view revisions.

It suits readers with a mathematical or physics background who want a map of nLab's material at the intersection of higher category theory and physics. It is a reference and navigation resource, not an introductory course.
