Thanks to this lecture, I was able to meet and examine concepts that I had only felt abstractly. It was a really helpful lecture because it covered everything from the forest to the trees one by one. I copied all the lecture subtitles into Word and printed them out to read. I love it. This is a lecture that I definitely want to recommend to a friend who is preparing for a similar job. Are you preparing another lecture, Gamja? If so, I'm really looking forward to it!!
