One of the best educational videos I have ever seen is “The Mechanical Universe.” This 52 part video series covers the three undergraduate physics classes: mechanics, electricity & magnetism, and a little of quantum mechanics. Best of all, these videos are free to view here; you have to register to see the videos. The videos were produced by California Institute of Technology and Intelecom in 1985. Yes, these are old videos, but give them a try especially parts 27 to 40 which covers electricity & magnetism really well. Complex concepts are explained using computer animations and physical demonstrations. I first saw these videos in high school and recently came across them again browsing the internet. I was overcome with nostalgia when I came across these videos. I recommend anyone interested in reviewing the basics of electromagnetics to view the related videos.

I recently found out that IEEE now offers online short courses on variety of subjects ranging from Aerospace to Robotics. In particular, they offer several online courses on Communications and Mirowave Theory & Techniques. One course that I highly recommend is “Basics of RF Power Amplifier (PA) Design,” by Steve C. Cripps for those who are interested in getting into active RF components. The PA is the most expensive part of a communication system, so demand for microwave engineers with background or knowledge of PAs is very high. In addition, Dr. Cripps has authored two highly regarded books on PA design (RF Power Amplifiers for Wireless Communications and
