Physics
Physics supplies most of the questions that the mathematics on this site was built to answer, and a good deal of the intuition for the answers. The recurring theme is that a physical law is usually a statement about a geometric object, and that choosing coordinates early hides it. Writing here covers mechanics, gauge theory, relativity and gravitation, and prefers the formulation in which the symmetry is visible.

Interstellar: a brane-bulk reading
A physics reading of Nolan's Interstellar (2014) in which Kerr geometry, Randall-Sundrum II brane-bulk coupling, and M-theory singularity resolution collapse the film's apparent plot holes into consequences of one maintained parameter: Gargantua's spin.

Reservoir Geometry: Riemannian Manifolds in Oil and Gas
Darcy's law recast as geodesic flow on a Riemannian manifold, pressure diffusion as the Laplace-Beltrami equation, and permeability tensor interpolation via SPD geodesics, with no_std Rust for embedded well-site monitoring.
