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
