To benefit most from the lectures, it's best to read the text ahead of lecture. Then, you can ask questions that wouldn't otherwise come up. Don't hesitate to ask questions during and after lectures. Outside of lectures you can always reach me by e-mail.

Syllabus: Chapters 2, 3, and 4 of
Peskin & Schroeder (see "main text" below)

Below are the videos of Zoom lectures (zip files) and the slides (what I was writing on my iPad during the lecture). You can use these for review or in case you were not able to attend the lecture. If you notice any incorrect or broken links or missing files for any past lecture, please let me know at the email below.

Note: Videos and slides for future lectures are  from the previous year - I will be replacing them with our actual lectures as we go. You're welcome to take a look at them while I haven't replaced them, though we might deviate from past lectures in certain ways.
