Particle Physics (2018) Topic 27: Renormalization 

Really, you did a great job! The analogy with the classical case was very effective too. Thank you so much Alex for these magnificent efforts! 👏

Very nice presentation, the crux of topic is concentrated very end with a beautiful twist to the story started. 👍🏽

Thank you for posting this on here. Wonderful exposition of a very confusing topic. I am a retired EE and and trying to get my head around basics of QFT and renormalization has stumped me and thank to you I am a little further along my quest . A big mental hurdle seems less forbidding now. Thanks again

Awesome lecture!

I don't know but this is where I miss professor Michael Short a bit... 🤭🤭🤭 But we still love you professor 🥰.

I like it how he calls it all a "fairy tale" :3

Thanks a lot, so funny!

but the photon is an off shell particle so the q2 can not be 0 !!!

🤗🤗🤗🤗🤗 Professor where r u?
