Interactive 4D Handbook lets visitors manipulate four-dimensional shapes and explore 4D concepts.
oPhysics
Visitors can choose from interactive simulations on oPhysics to explore and learn about physics topics.
About oPhysics
oPhysics is a collection of interactive physics simulations organized by category. Visitors can select a simulation or open a category to read descriptions of its simulations.
The site was created by Tom Walsh, a retired high school and AP Physics teacher, using GeoGebra software. It is described as a work in progress with new content added as time allows, and content may be used for non-profit educational purposes.
