I just published a new lecture — not on quantum physics this time, but on general relativity. It’s titled Lecture on General Relativity and, like my earlier papers, it’s written in collaboration with GPT-4 — who, as I’ve said before, might just be the best teacher I (n)ever had.
We start simple: imagine a little bug walking across the surface of a sphere. From there, we build up the full machinery of general relativity — metric tensors, covariant derivatives, Christoffel symbols, curvature, and ultimately Einstein’s beautiful but not-so-easy field equations.
What makes this lecture different?
- No string theory.
- No quantum gravity hype.
- No metaphysical hand-waving about time being an illusion.
Just geometry — and the conviction that Einstein’s insight still deserves to be understood on its own terms before we bolt anything speculative onto it.
If you’ve enjoyed earlier pieces like Beautiful, but Blind: How AI Amplifies Both Insight and Illusion, or my more pointed criticism of pseudo-GUTs here, this one is part of the same lineage: a call to return to clarity.
