Welcome to The MIT Department of Physics Technical Services Group website.

About TSG
The Technical Services Group (TSG) at MIT's Department of Physics provides technical and teaching support for undergraduate courses at MIT. Our many rooms of physics demos, accumulated over the past century, display subtle physics concepts ranging from electromagnetism, to kinematics, to optics.

The undergraduate physics courses at MIT include lecture courses, as well as the Technology Enabled Active Learning (TEAL) studio classroom courses. For more information on the MIT Department of Physics visit their website, or see MIT OpenCourseWare to download free course materials.

We provide support for most variants of 8.01, 8.02 and 8.03 classes in the form of:

  • Demonstration setup, execution and breakdown

  • Laboratory setup, execution and breakdown

  • TEAL classroom teaching assistance

  • General TEAL room support and maintenance

Additionally we occasionally provide some of the above services for departmental open houses, graduations and other special events.

Random Cool Demonstration!

Fluorescent and Neon Tubes in VdG Field (D 24)

Keyword: Electric Fields

A fluorescent tube swings at the end of a long plexiglass rod. It is made to rotate and then brought near the VdG generator. The tube lights up when pointing radially away from the VdG. The same can be done with a small neon tube. Also, the tubes can be hand-held and made to flash by grounding. This demonstration is done only with the large VdG.
