Thank you for the very nice lecture, Prof. Osborne! Finally, I get the 'physical picture' on renormalization after taking your lecture (I took two QFT lectures before).

Renormalisation has never been better explained to me than in your lectures.

Many thanks for your comment-I am happy to hear you found them helpful! I spent a long time trying to understand renormalisation and wanted to find a way to explain it in information theoretic terms. If you are interested in this topic we wrote some papers on the RG that might be interesting. See e.g., arxiv.org/abs/1310.3188 Sincerely, Tobias Osborne

Thank you very much for uploading your great lectures. I've been doing "shut up and calculate" for renormalization chapter, and I was not convinced about it. Whether it is a brainwash or not, at least I can appreciate what I am doing now.
