# About

This is a catalogue of the intersection of the mathematics and physics I find interesting and the things I think I can give a half-reasonable explanation of.

The themes that really interest me are **alternative perspectives on analysis and geometry **(divergent series, non-standard analysis, Henstock-Kurzweil gauge integral, Grassmanian geometry), **geometry of physics **(principle of least action, Poisson brackets), **symmetry – conservation and breaking **(Lie groups and algebras, Noether’s theorem, group theory and particle multiplets, Goldstone bosons, quantum decoherence and einselection, CPT theorem, arrow of time), **quantum chemistry** (first principles models of atoms and molecules, bonds and bands, states of matter, reaction rates, electromagnetic radiation and computational approaches).
