A visual representation of Minkowski spacetime appropriate for a student with a background in geometry and algebra is presented. Minkowski spacetime can be modeled with a Euclidean fourspace to yield accurate visualizations as predicted by special relativity. The contributions of relativistic aberration, as compared to classical prerelativistic aberration, to the geometry are discussed in the context of its visual representation

Visualization of Classical and Relativistic Spacetime Geometry  
Herein we devise, explore, and test an elegant theoretical spacetime model to enable realistic visualization of special relativistic effects. Images and animated videos are provided.

Two early examples of interactive 4D models, follow. The first is a straightforward Euclidean 4D space depicted by a display similar to that of a 3D CAD pacakge. The second is a 4D Minkowski spacetime displayed the same way, showing relativistic distortions and infinities at lightspeed.

My Erdös Number  5:
The Paul Erdös number represents
the separation of a scientist from the famous mathematician Paul Erdös in
terms of coauthoring mathematical research articles, and is an easy way
to lose a lot of time browsing bibliographies and the Internet (there are
tools). I determined my Erdös number to be 5 as follows:
Don V Black > Renato Pajarola > Peter Widmayer > Emo Welzl > Boris Aronov / Paul Erdos
