I have taught nearly 1500 students since I started at Georgia Tech in 2003. In that time, I have delivered (generously) about 7 solid years of “watch time” to engineering students physically in the classroom. In the 5 year existence of my YouTube channel of electromagnetics lectures, the lectures have generated nearly 8 years of total watch time. These are just low-quality recordings of niche topics with virtually zero production value.
As one of my colleagues said, “If you don’t flip your classroom, the students will do it for you.” This all underscores a huge demand for low-cost technical lectures on the internet. For my money, the best electromagnetic video collections are the “bite-sized” topical lectures of Prof. Cynthia Furse at University of Utah.
