Videos for PHY 3250, Biological Physics

Last fall, I recorded my lectures for my PHY 3250 (Biological Physics) class, and posted them on YouTube. The videos are not great; they are nowhere near professional quality, and often the chalkboard is difficult to read. I originally recorded them as a backup for my students, in case they missed a class or wanted to review something they heard me say in a lecture. Nevertheless, I think that students and instructors may find these videos useful.

My Biological Physics class covers the first ten chapters in Intermediate Physics for Medicine and Biology. Topics include biomechanics, fluid dynamics, the exponential function, biothermodynamics, diffusion, osmotic pressure, bioelectricity, biomagnetism, and feedback.

Some videos are missing: Monday, September 30 was Exam 1; Wednesday, October 30 was Exam 2; Wednesday, November 27 the class played Trivial Pursuit IPMB; and Friday, November 29 was the day after Thanksgiving.

If you are sitting at home self-quarantining with nothing to do, feel free to binge.
