Lecture Schedule

Future lecture topics are subject to change. Over time we will add links to relevant textbook chapters / lecture notes; links to future lecture notes, videos, and other resources are placeholders. Exam dates are fixed. Notes that have been recently revised (however lightly) are marked ✍️.

Videos with technical problems are marked ⚠️. For most topics, scribbles and videos from Jeff's Fall 2022 offering of the course are available on a separate page.

Lecture videos are available on a separate page. New videos should be available at most a day after each lecture.
