I just finished watching part one. A good primer definitely worth the 1 hour and 15 minutes to watch. Some of it hits detailed electrical engineering, but Dr. Asirvatham uses the whiteboard a half dozen times to bring it down to layman level, so don't be intimidated.
And here is a pdf I made of the presentation slides, as well as comments I took from the presenters.
I hope to view part 2 in the next day or two and will post slides and notes for that too.
