Quantum field theory textbooks have been lying to you or have left you confused. For a typical passage like the following from Peskin&Schroeder - what does it mean to do a change of variables on an ill-defined path integral? For perturbative QFT, my paper resolves this issue: 🧵

Excited that my new paper on understanding LLMs is out, pushing how far we can describe LLM predictions via simple statistic rules. Bonus: I also discover a novel way of detecting overfitting *without* using a holdout set. So are LLMs just stochastic parrots? You be the judge. 1/

So Sabine Hossenfelder deleted my post on her blog criticizing @ericweinstein after I called out her grift supporting Eric and his friends. And she also blocked me on X. Looks like Sabine needed to cover her tracks since the no-holds barred science critic shtick is up. 🧵 1/

Dear Ed, let’s bury the hatchet with our disagreements over @ericweinstein and work things out together - constructively and in good-faith. Since you’ll be coming to London in December, I would love to discuss the details of Geometric Unity as you understand them - grand

I can attest that @ericweinstein is a brilliant mathematical physicist. I recently did a deep dive into his Geometric Unity theory and I think it has the potential to unify all forces of nature in a beautiful & novel way; explain dark matter; and give a new explanation of dark

The problem with Eric Weinstein is that his theory has already been discredited, per my article hosted on Sabine's blog. Odd that you left that part out @skdh but instead praised his supporters as if it were some noble heroism. backreaction.blogspot.com/2021/03/guest-…

Published on the arxiv today is my response to @PiaMalaney + @ericweinstein's work on "Economics as Gauge Theory" which Eric Weinstein presented at UChicago last month: arxiv.org/abs/2112.03460 Summary of the objections is as follows: (1/n)

Sabine Hossenfelder has officially cited Eric Weinstein's Geometric Unity in her latest paper. It's only proper that entertainers cite other entertainers:

Was fun being interviewed on Professor Dave Explain's 3M sub YouTube channel to debunk @ericweinstein's theories of physics and economics (with @PiaMalaney). The video is a 2for1 since it also debunks @BretWeinstein's conspiratorial claims about telomeres, vaccines, and more: 1/

Check out my latest video on @DeepMind’s recent “AI for Mathematics” breakthrough that enabled mathematicians to establish new and significant theorems. I cover the knot theory background, machine learning basics, and the Nature paper youtube.com/watch?v=UPCI1-…
