I began watching this class with the expectation that I would be quickly lost. Instead I found Dr. Guth to be an excellent instructor who develops the topic in a way that, even being many years removed from my college math, I was able to follow. Some of the areas can be a bit dry but, hey, this is science not entertainment. If you want to skip all the development of equations which can be a bit mechanical, he does a quick 10 min. review of the previous class at the beginning of each lecture.
Very interesting, Dr. Guth. I viewed the first lecture. Looking forward to viewing the rest.
