Math Will Never Be the Same Again… | Yang-Hui He

Curt or Yang-Hui He, I have a question at the end. I’m fine if neither of you wants to answer it, and I don't blame you if decline. But I’ll ask anyway.

Particle physicists first uncovered string-like vibrations in the late 1960s. The cause, though unclear then, proved boringly simple: protons, neutrons, and similar particles contain the universe’s smallest strings. These “hadronic” strings are the bungee-cord-like orbitals of quarks bound by color-electric charges. Their quantized vibrations were the sources of the string-like vibrations observed in particle colliders.

Other than one brilliant young physicist who died tragically in a climbing accident (his rope snapped), I’ve never encountered a string theorist who admits in public that “super” string theory originated with physical, particle-and-force quark orbital strings. These days, many prefer to pretend that Witten came up with the idea entirely on his own.

The actual origin is that two fellows later grabbed the hadronic string math, discarded the physical particles and forces, and rescaled the resulting no-longer-physical math to be 20 orders of magnitude smaller and 20 orders more energetic. The nominal goal was to construct point-like particles such as electrons.

My question is this: If string vibration math is as fundamental as many claim, why does the math no longer include the particles and forces needed to implement physically meaningful strings at the new energy scales?

The notion that we have entered a position where we should accept truths that we cannot possibly grok is terrifying.

All things in the universe are subject to change, evolution. Things are dynamic. Not static. Does that include math? Is math eternal? Unchangeable? Or is it a byproduct of our level of reality? …where causation lives. Perhaps math is just a reflection of a deeper truth. Or of a deeper form of math that allows the math rules themself, to bend into new maths.

Thanks for sharing! I'm looking for advice on sending USDT from my OKX wallet to Binance. I just get 12 words: clarify cash circle pretty surprise supply slide club solid area wear case. Anyone can help?

Wow, what an ad get!
Congrats on your success, Kurt
And for stimulating my curiosity!

Math is dead Physics is dead. AI will kill every human activity.

Thank you Curt for another interesting video!
In the future I would personally prefer if You drove the "interviews" and topics of disussion and did not allow quasi lectures.

Math is it's own meta.

44:18 It looks like the horizontal axis represents each separate IMO competition, with the bars signifying the number of no/bronze/silver/gold medalists in each. Nothing to do with Terrence Tao "retaking the test," lol.

It appears that String Theory has nothing to say about the origin of the fine structure constant, which is a dimensionless number which is found quite often in combination with π. 50 years of mathematicians marking their own homework. I've got a mark for progress on this question 1/10.

This is my fear.😢
