Online lecture today

As announced on the last lecture, today's lecture will be given in the form of prerecorded video clips. Lecture notes and video clips can be found here. Note that the video clips are actually full lectures, so the total time of these clips are fairly long. However, the clips will be available so that you can watch these clips whenever you like. Note also that the clips are not subtitled. Please let me know if you want subtitled clips.
