== Description ==

I am developing methods to improve the understanding of relativity,
especially though physical interpretation (from a spacetime viewpoint),
computation, and visualization of spacetime structures.

 * Spacetime diagrams
 * Visualization of Proper Time along a worldline (piecewise-inertial and piecewise-uniform-acceleration)
 * Spacetime Geometry (via Cayley-Klein Geometries, a unified approach to Galilean and Special Relativity)
 * Visualization of Tensor Fields and Differential Forms
