Many people have already said many amazing and well deserved statements about how wonderful this
lecture is. I'd like to add something, though. I would like to mention what a great teacher Gabriel
is! His use of visual aids, and the way he approaches teaching his effects makes the concepts easy
to understand. Having a deep understanding of a concept does not frequently translate to being able
to explain it well, but Gabriel is the exception to that rule. He has clearly thought deeply about
how to best convey his methods, and that makes a huge difference. Thanks for a great lecture!
