PHYSICS 320 - Modern Physics Instrumentation
Fall 2000 & Spring 2001

Analytical electron microscopes are used to teach principles of electron optics and solid state physics. A very low student-to-instructor ratio is essential, with a preferred ratio of 1:1 or 2:1.

Computer-based learning is coupled with hands-on use of the instrument and traditional lecture, text, and whiteboard instruction to provide multiple perspectives of complex principles.
