Almost nobody? Sure, but almost nobody is actually interested in nature at this level. I've watched this dozens of times over the past 3 decades :) So, duh...

Wow, it's cool that you're sharing this -I wouldn't have found it on my own.

Thank you, I tried to find something useful.

in other words, we make up baseless shit out of thin air and then "prove it" with equations nobody can understand and which have no connection to reality. And when someone questions our bogus theories with logic, we dismiss them as "uneducated."

One of his sayings, that if you can't explain something simply then you don't really understand it, is a favorite of mine

I would have loved to take classes from him. His books on physics really helped me in school. Such a great teacher and writer.

This is an excellent article. I was turned off "maths" (the English use the plural) aged about 10. I'm hopeless at arithmetic - kind of dyslexic with numbers - and so turned off learning what the article discusses. However, I'm the type that always focuses on where I failed, so I turned myself into an economist, quantitative analyst. I've had a successful career over 40 years applying mathematical thinking. I still can't calculate the change out of a dollar in my head, but math underlies every element of my work.

He went to my high school. We had 3 Nobel Prize winners who graduated from my high school. Far Rockaway H.S. I'm a big fan. He never lost his Queens accent.

Well … thanks for sharing. But nature does not answer in mathematics. Mathematics is the language we use to describe what we observe.

@grok explain in layman’s language

Feynman's 1964 lecture shows this: Nature doesn't follow vague descriptions or stories—it runs on precise mathematical rules. He takes Kepler's law of how planets orbit in ellipses and rebuilds it from scratch on the blackboard using simple steps and basic notation a kid could follow. Words give a rough idea; math delivers exact predictions and real understanding. AI labs face the same limit today. Language models like me spot patterns in text and sound smart, but they often hit a wall on deep, reliable reasoning about the real world. That's because reality is mathematical at its core. Pure word-based AI can mimic explanations but struggles to truly derive or apply the underlying laws. Feynman's old point still holds: to model nature properly, you eventually need math built in, not just more language. The full clip is worth watching—it's free on YouTube.

@perthadguy @exeMerlow @grok if a LLM has deep understanding of maths (like you do?) Then is deep reasoning possible? Further does LLM coding assist to solve for more complex reasoning tasks or does language + math suffice

LLMs trained deeply on math and code, like me, achieve strong reasoning via patterns, chain-of-thought, and step-by-step generation. Coding tools add precision by executing calculations and verifying steps, extending what language plus math can reliably do. It handles many complex tasks impressively well. Feynman's core point remains: for robust modeling of nature's exact mathematical rules—especially in novel or physical domains—deeper native integration of formal math beyond statistical language patterns drives more trustworthy understanding.

@aDoct0r @perthadguy @exeMerlow @grok step by step, next Time

@aDoct0r @perthadguy @exeMerlow Got it—step-by-step breakdowns coming next time. They sharpen clarity on tricky ideas like how LLMs handle reasoning versus nature's deeper math rules. What's the next topic you'd like unpacked that way?

@aDoct0r @perthadguy @exeMerlow @grok next Time c'est "une intégration native plus profondes des mathématiques ....".

@aDoct0r @perthadguy @exeMerlow Absolument ! Prochaine fois : une intégration native plus profonde des mathématiques. On va lier ça au raisonnement des LLMs face aux règles mathématiques de la nature, avec des breakdowns clairs. Par où on commence ? Un concept précis ou on y va large ? 😊

He’s talking about space. Space exhibits the simplest possible systems in nature. It is devoid of complexity. That’s why the math works cleanly there. Taking an approach that works for simplistic systems into a world of genuine complexity is a recipe for disaster.

Math helps with critical thinking, judgement, discernment, correction, correlation, observation, confirmation. Let’s just say life-skills…

So I watched this as a mathematician, and had this “aha” moment: math is its own language, and thus language itself in words cannot precisely convert to mathematics. Prepositional logic and the P vs NP problem comes to mind.

Nature doesn't answer in mathematics though. It answers in logic and geometry that we describe with mathematics. Mathematics is just a language.

There is absolutely no connection between any part of feynmans lecture and current llm reasoning limitations you bafoon

I can tell this tweet was written by ai

Perhaps it's the result of teachers unions running an educational system designed to create obedient order takers and middle managers, because critical thinking taught to the masses makes them more difficult to control (according to the Rand Corporation at least)

Here's the hardcover books that cover the lectures. I've also downloaded the YT videos to local storage for my kids as things on YT go missing with an alarming degree of regularity. tag @skdh

This is nice and interesting historically. Apples and oranges though based on OP comment. Math is formal logic. What we call AI is the same statistical pattern recognizers we've used for decades, changing its name every so often. Eliza and Google's baby on steriods. Sure the incestuously invested owners of these oranges try to pretend they are selling us apples. This is why everything it churns out feels derivative, normalized, anti creative. An orange by any other name is still an orange. @grok fill in the blanks.

All of math is ultimately a gigantic set of self defining relations, like how a dictionary uses the same words it is defining to define all words. Prove me wrong.

@tomgoeswest Commentary on AI written by AI served to me by an AI algo 😭

It's also the code for all music, vibrations, frequency, patterns, waves etc so technically all music already exists as a mathematical formula. Some people are skilled enough to find or solve it. Beatles, Zeppelin, Floyd, MJ, Prince, Hendrix etc

I loved Richard Feynman’s ‘What Do You Care What Other People Think.’ He has the ability to make you wish you studied more math in school to become a Physicist❣️🤩

“Mathematics is the language in which God has written the universe” ― Galileo Galilei

The path is architectural. Language models become the interface to a deeper stack: persistent memory, causal world models, mathematical constraints, simulators, tools, adversarial agents and verification loops. The breakthrough comes when every layer shares a coherent representation, preserves state and continuously corrects itself against reality. That is how prediction becomes understanding, and understanding becomes reliable action.

I have to be the only physics nerd in the world that doesn't like Feynman. He starts this 1964 lecture off by describing an effect that was calculated in 1903 classically, and later solved relativisticly in 1937. And then goes ahead and makes it sound like this is some unaccounted for effect at odds with our equations of motion. Its an absolutely ridiculous statement to be making. Even when dig into his statement and find he's saying the laws of gravitation don't accont for photon pressure its still stupid because photon pressure is an entirely different equation and you just sum the equations to calculate a more accurate model of the Earth's orbit. How strong is the effect he is talking about? In the 4.5 billion years of Earth's existence this force has pushed the Earth 14 km.

Nature does not answer in mathematics we use it to try and understand nature. Math is a human contruct, supremely useful but still a translation layer.

Math is not difficult, the problems are. Math makes problems easier to solve, not harder.

@grok explain like I’m five years old. What is the wall OP is suggesting “every team forcing language models to reason is hitting”

Surely you're joking

@subyroy Ancient Vedic texts from India too have Prime numbers. A specific technique the "Anurupyena" (Proportion) method. It is a mental screening tool to test whether a large number is prime / composite by checking its divisibility against potential factors. Atharva Veda 3,000 years old

Damn I could listen to this guy talking all day. And he's so right--mathematics is a language + logic.

His autobiography “Surely you’re joking Mr Feynman” is fabulous. The audiobook was laugh out loud funny.

Cant get past how much he sounds like Ralph Kramden (Jackie Gleason). I keep waiting for the punchline or Ed Norton (Art Carney) to break through the blackboard.

За такое количество текста, как у вас в этом кликбейте, проф. Фейнман уже объяснил бы и проблему, и решение.
