Studying null and time-like geodesics in the classroom
In a first course of general relativity, it is usually quite difficult for students to grasp the concept of a geodesic. It is supposed to be straight (auto-parallel) and yet it 'looks' curved. InExpand

Charged particles constrained to a curved surface
We study the motion of charged particles constrained to arbitrary two-dimensional curved surfaces but interacting in three-dimensional space via the Coulomb potential. To speed up the interactionExpand

Circular orbits in the extreme Reissner-Nordstrøm dihole metric
We study the motion of neutral test particles in the gravitational field of two charged black holes described by the extreme Reissner-Nordstr{\o}m dihole metric where the masses and charges of theExpand

Numerical Chladni figures
Chladni patterns of vibrating membranes or thin plates faszinated the people already in the eighteenth century. As a simple way to visualize acoustic phenomena it is a valuable experiment forExpand

Visual appearance of wireframe objects in special relativity
The visual appearance of a moving object in special relativity can be constructed in a straightforward manner when representing the surface of the object, or at least a wire frame model of it, as aExpand

Twin Paradox in de Sitter Spacetime
The 'twin paradox' of special relativity offers the possibility of making interstellar flights within a lifetime. For very long journeys with velocities close to the speed of light, however, we haveExpand

IDEAS: Immersive Dome Experiences for Accelerating Science
Astrophysics lies at the crossroads of big datasets (such as the Large Synoptic Survey Telescope and Gaia), open source software to visualize and interpret high dimensional datasets (such as Glue,Expand
Britannia Rule the Waves
The students are introduced to navigation in general and the longitude problem in particular. A few videos provide insight into scientific and historical facts related to the issue. Then, theExpand
2019 IEEE Scientific Visualization Contest Winner: Visual Analysis of Structure Formation in Cosmic Evolution.
We use visualization techniques from the fields of particle visualization, flow visualization, volume visualization, and information visualization to extract and highlight the development of active galactic nuclei and filament structures formed by the particles. Expand
Visual exploration of 2D autonomous dynamical systems
We present ASysViewer, an application for the interactive visual exploration of two-dimensional autonomous dynamical systems using line integral convolution techniques for visualization, and grid-based techniques to extract critical points and separatrices. Expand
