Most lectures — regular or extra — for the Classical Electrodynamics (II) class are mirrored on Zoom and recorded on the cloud, with the records available on Canvas. Unfortunately, due to techical glitches some lectures do not get recorded. For these un-recorded lectures, I am going to scan my notes, post them on my web site, and link them to this page.
As of this writing, there were no unrecorded lectures.
