Schedule

As the syllabus says: This year we'll often "flip the classroom," to make the best interactive use of our precious synchronous class meeting times. Thus, many of the class meetings will be used for Q&A, discussion, enrichment, and collaborative-problem solving. You'll be expected to watch lecture videos ahead of time, which will be announced on Piazza and posted below.

Warning: The schedule below may change! It should be correct up to the present, but for future dates, it shows last year's timetable and materials (adjusted to this year's dates). Watch Piazza for important updates such as new lecture videos, homeworks, and due date. Links to future lecture slides and homeworks currently point to last year's versions.
