This film on The Stern-Gerlach Experiment featuring MIT Professor Jerrold R. Zacharias was produced in 1967 as part of the College Physics Film Program by Educational Services, Inc. (ESI), later Education Development Center (EDC), which grew out of the project known as the Physical Science Study Committee (PSSC). Some of the content was developed by the Science Teaching Center (STC), later Education Research Center (ERC), at MIT.

This is a 16mm projection filmed by a digital camera.

This apparatus is currently in hibernation but had been used for a number of decades in MIT's Junior Physics Laboratory while having its parts gradually replaced or upgraded with components like stepper motors.
