Using computer graphics we create first-person visualizations of relativistic scenes.

We visualize the geometry of relativistic spacetimes by means of sector models.

We develop new ways of introducing the general theory of relativity. These are non-mathematical but quantitative. Our goal is to make more of this theory accessible to high school students, undergraduate students, and the general public.

We study curricula, teaching materials, and students' conceptions to analyze the status quo of general relativity in school.
