UVA Virtual Lab

ranger

A very vivid approach to learning a few concepts in engineering and physics. Some topics are:
How Semiconductors and Transistors Work (1)
Making an Integrated Circuit
Scanning Electron Microscope (SEM)

The above are a few of my favorite. They have done a tremendous job in providing easily understandable explanations and graphics\videos. They even do a better job than my text did to explain (1) :)

They also have a fairly decent series in Quantum-dot Cellular Automata (QCA).
