# Advanced physics methods and spacetime

> Explore perturbation theory, scattering, variational quantum estimates and a conceptual bridge to general relativity.

Prerequisites: Eigenstates, inner products and nondegenerate quantum mechanics.

Short self-study course; not an accredited qualification or a complete university syllabus.
