The material presented in these two videos is more difficult and requires more of an understanding of quantum mechanics than the unstarred lectures.

Visit the Nuclear Wallet Cards website for tables that contain atomic masses, half-lives, etc. of all known nuclides.

Autonomous Systems

Stability of Solutions to Linear and Almost Linear Differential Equations How to determine the type of critical point- improper node, proper node, saddle point, spiral point, or center- of a linear autonomous system is explained. Then, these results are extended to almost linear autonomous systems. Included is a discussion of the stability of solutions to the linearized simple pendulum, simple pendulum, and damped pendulum problems. The Python scripts that were used to generate the plots of the trajectories are posted at the Code page.
