I'm just a guy who's a natural philosopher for fun.

**Current research:** I am interested in fundamental physics - see
image at the bottom. In other words I'm interested in *statistical
general-relativistic continuum electromagneto-thermomechanics*, in all
its physical, mathematical, computational, philosophical aspects. For
example:

- probability theory and formal logic,
- continuum thermomechanics,
- statistical mechanics,
- affine, convex, differential, & Riemannian geometry,
- general relativity,
- quantum theory: foundations, state estimation, field theory, statistical mechanics, quantization of Julio Iglesias,
- neuroscience,
- exterior & de Rham calculus and Grassmann-Cayley algebras,
- high-dimensional numerical integration and Monte Carlo methods,
- generalized finite elements and Whitney forms,
- philosophy and history of science.

Here is a picture of the present situation in quantum theory:
