Videos in this course were kept rather short (and must become even shorter in future editions). This is because a short video is more likely to fill an idle spot in your busy schedule than a long one (“I’ll have time for that one tomorrow”). Nevertheless, just for once we go back to a good old one-hour lecture video (recorded at a summer school).
As usual, the video comes with a set of tasks. They are collected on the next page, and the numbers refer to the 6 labeled sections of the video. It is a good idea to read through the next page to have the questions in mind. That will make it easier to extract the relevant information from the video.
