Lectures from my introductory QFT course last year: https://www.youtube.com/playlist?list=PL04QVxpjcnjhg3WHxG8sC1QHrpY_7dnoz
This is a fairly standard course that we offer at ICTS annually. I don’t think I said much that was new. We keep the Moodle open for anyone to join and view. A few months back, an unidentified person downloaded the lecture videos and uploaded them to Youtube – the same person also took them down a few weeks later. To my surprise, I heard from a number of students from other institutes who said they had found them useful. So we have now uploaded this ourselves.
