PHYS 225 - Modern Physics

5 CR

Presents the special theory of relativity, key phenomena, and experiments of modern physics that led to a break from classical views. Includes an introduction to quantum mechanics. Research based active engagement, pedagogical methods and hands on activities assist conceptual development.

Recommended: MATH 238 or concurrent enrollment.
Prerequisite(s): MATH 153 or MATH 254 and PHYS 123.
