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!

Electric Field Lines (D 16)

Keyword: Electric Fields
A sealed transparent acrylic container filled with suspended fibers fits on the overhead projector. Five special slides that are able to show different fields fit in the container on the overhead projector. A special piezoelectric pistol with an output of 5 kV is used to charge the slides. The fields that can be shown are:

1. parallel plate capacitator
2. a circle and a point
3. a pattern of two concentric circles that demonstrates electrostatic shielding
4. two like-charge points
5. two unlike-charge points
