These videos were initially developed from the college courses I taught at UNC Asheville. The Light and Sound courses are for the general student. Theoretical Physics, Electromagnetic Theory, Modern Optics, and General Relativity are aimed at physics, mathematics, and engineering majors with at least two semesters of calculus and intro physics. Notes for some of these courses are being posted at either of the two links listed below under Links. I hope to add more during my retirement.
