Mystery Image Archive
A short article describing a Van de Graff demonstration using a bat made from fake fur. The bat hovers over the Van de Graaff generator and under the right condition it can fly and land over the lap of a student.
UVA Virtual Lab: Van de Graaff Generators - Dec 23, 2010
These series of pages provide a detailed tutorial on the principals behind the operation of a Van de Graaf generator. It is par of the UVA Virtual Lab collection.
PhET Simulation: Simplified MRI - Mar 12, 2010
This is an interactive simulation on the topic of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI). The user can change the applied magnetic field and the RF signal and observe the effect on spins. In the NMR mode, the user can choose between various from among several atoms. In the MRI mode, the user can elect to add a tumor to the head being visualized.
