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!

Amber and Glass Rods with Tinsel (D 1)

Keyword: Electric Charge
An amber rod rubbed with fur is charged negatively. The rod is brought into contact with tinsel. The tinsel becomes charged and flares out. Bringing the charged amber rod close to the tinsel repels the latter. The positively-charged fur, however, attracts the tinsel. A glass rod rubbed with silk is charged positively and also attracts the tinsel. Touching the tinsel discharges it. The demonstration can be repeated starting with the glass rod. Ref: hb x 1
