These Flash animations provide clear visual representations of a broad range of topics in physics. Many of these are computer representations of common physical concepts with, in most cases, short explanations of the physics being displayed. Many of the resources provide simple controls for the user to explore the simulation.
Some of these resources are longer, multi-page tutorials explaining a concept in more detail. These step through explanations with short, readable pages and integrated illustrations.
The breadth of materials is a notable strength of the collection. Topics range from basic introductory mechanics through non-linear systems and quantum mechanics. Some of the high points are the animations illustrating micrometer and oscilloscope operations, the quantum mechanics examples (especially the Bell's theorem animation), and the relativity animations.
