Teaching general relativity with sector models — •Ute Kraus and Corvin Zahn — Universität Hildesheim

In teaching general relativity, the use of models can help to build geometric insight. Geodesics and the curvature tensor are of particular interest. Sector models visualize the geometry of specific curved spacetimes; these models are based on the Regge calculus and represent two- or three-dimensional subspaces true-to-scale. Geodesics and curvature tensor components can be inferred from them. This talk presents several examples of sector models, including models for a Schwarzschild black hole, a neutron star, and a wormhole, and discusses the potential of this approach.
