I watched this entire semester. I got an A in gen chem last semester, largely because professor Sadoway explained the topics much more clearly than my own professors did.

Thanks so much for these videos. They are all very helpful.

I am pushing 60, and I think I speak for many people my age who finished their own education before the advent of personal computers and the internet. This avenue for learning is the most intelligent and correct use of the human intellect I have ever experienced. It is right in every way. I am free to select whatever I am interested in, and I can be educated by the best minds in the country. I don't have to qualify to attend, and I don't have to pay a fee. I am shocked that there are not millions, and millions of viewers. Our country is struggling to educate young people while you are already providing the solution. You have really struck the forces of darkness a heavy blow with this great, and unselfish strategy.
