The lessons in chronological order so far1 (the list will be complete at the end of the semester):
Sometimes lessons span more than one lecture but this is not explicitly marked. The dates associated with each lesson indicate the day when the lesson was introduced for the first time.
Most of the teaching material is available as Jupyter notebooks and linked from the lesson pages (typically, near the bottom). For lessons in progress, links initially only point to incomplete materials. Full materials including solutions to in-class problems are always made available after the completion of the lesson.
The most recent lesson in the list on this page started on May 7, 2018. ↩
