Relativity visualized

Schwarzes Loch

The theory of relativity holds a certain fascination for many people. At the same time it is often regarded as very abstract and difficult to understand.

Part of the difficulties in understanding relativity are due to the fact that relativistic effects contradict everyday experience. Motion, for example, is a familiar process and everybody "knows from experience" that it entails neither time dilation nor length contraction. A flight with half the speed of light could correct this misjudgement but is not on offer.

A possible alternative are simulations. Images, films and virtual reality let us in a sense experience relativistic flights, gravitational collapse, compact objects and other extreme conditions.

New contribution: Sector models - a toolkit for teaching general relativity: III. Spacetime geodesics
Sector models permit a model-based approach to the general theory of relativity. The approach has its focus on the geometric concepts and uses no more than elementary mathematics. This contribution shows how to construct the paths of light and free particles on a spacetime sector model. Radial paths close to a black hole are used by way of example. We outline two workshops on gravitational redshift and on vertical free fall, respectively, that we teach for undergraduate students. Sector models - a toolkit for teaching general relativity: III.

New contribution: Sector models - a toolkit for teaching general relativity: II. Geodesics
Sector models are tools that make it possible to teach the basic principles of the general theory of relativity without going beyond elementary mathematics. This contribution shows how sector models can be used to determine geodesics. We outline a workshop for high school and undergraduate students that addresses gravitational light deflection by means of the construction of geodesics on sector models. Geodesics close to a black hole are used by way of example. Sector models - a toolkit for teaching general relativity: II. Geodesics.

690. WE-Heraeus-Seminar: General Relativity as a Challenge for Physics Education
February 10 - 15, 2019, Physikzentrum Bad Honnef, Germany. Aims: The goal of the seminar is to promote the scientific exchange of ideas and research results on the teaching of general relativity. The seminar will be focussed on the secondary school and undergraduate levels. Target audience: Physics education researchers, physicists, and physics teachers are invited to participate in the seminar. PhD and master students are encouraged to apply.
