Heinz Hopf discovered this in 1931. Roger Penrose called it "an element of the architecture of our world." Eric Weinstein brought it up on Joe Rogan - and the silence in the room said everything.
The Hopf fibration maps a 4D hypersphere onto a regular sphere using circles that never intersect but each links through every other exactly once. It shows up in at least 8 areas of physics - including the Bloch sphere geometry that every qubit in a quantum computer lives on.

this is f*cking gold
Andrej Karpathy joined Anthropic five weeks ago.
A friend on his team just showed me the exact LOOPS.md file he actually uses.
I dropped it into my setup. The very first response was different.
Not slightly different. Completely different.
Claude stopped giving generic answers and started working exactly the way I think.
You don't talk to the model anymore. You build the system that talks to the model for you.
Bookmark it before it gets lost in your feed.
Read it now, then check the article below.
Anthropic posted the best prompting lecture I've ever seen... and deleted it two days later.
I watched the recording last night and kept pausing it. Each time I opened Claude to test what they showed.
Two Anthropic engineers showed in 24 minutes how the Claude team actually uses it.
Not tips. Not hacks. The way they actually talk to Claude. Every day. For real work.
After 3 minutes you'll want to rewrite every prompt you've ever sent.
Life after discovering your Obsidian vault can run 9 automations overnight while you sleep.
This is what happens when you actually build the N8N layer underneath it.
A completely rebuilt research system.
Andrej Karpathy quietly shipped the best second brain idea in years
not an app. a pattern.
let an llm maintain a wiki of your notes. you dump sources, it reads them, links them, files them. knowledge compounds like interest.
someone built it into a free claude code plugin. setup is two commands:
claude plugin marketplace add AgriciDaniel/claude-obsidian
claude plugin install claude-obsidian@agricidaniel-claude-obsidian
then open obsidian, open claude code in the same folder, type /wiki.
that's it. your notes are now queryable by claude and they get richer every time you read something.
bookmark this. best thing you'll build this weekend.
A toothpaste company has quietly killed the entire market research industry and nobody is talking about it.
Colgate published a paper showing you can predict real purchase intent at 90% accuracy by simply asking LLMs to roleplay customers.
And this is beyond insane.
If you ask an AI, "Rate this product from 1 to 5," it gives safe, middle-of-the-road garbage.
So researchers invented a method called Semantic Similarity Rating (SSR).
Instead of asking the AI for a number, they asked it to roleplay.
They gave the LLM a demographic profile. They showed it a product concept. And they asked it to write down its raw, unfiltered thoughts.
Then, they used a semantic model to translate those written thoughts into a numerical score.
The results are staggering.
Tested against 57 real corporate surveys and 9,300 actual human responses, the synthetic AI consumers matched real human buying behavior with 90% reliability.
They perfectly mirrored how different age brackets and income levels react to price changes.
And they provided detailed, qualitative feedback that was deeper and more critical than what actual humans wrote.
This destroys the economics of traditional market research.
You don't need to wait a month to see if a product will sell.
You can simulate 1,000 hyper-targeted customer interviews overnight.
You can A/B test pricing across every demographic instantly.
A man spends 50 years teaching at MIT.
He knows his time is running out.
So he records one last lecture — everything he knows, distilled into a single hour.
He died 5 months later.
This is that lecture.
The most important hour you'll watch this week. 👇

🚨 Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude.
Taught by the people who built it.
Free. No registration. No paywall.
I've seen $300 courses that don't cover what they teach in the first 8 minutes.
Watch it and bookmark it now.
This 2 hour Stanford lecture on AI careers will teach you more about winning in the AI race than every piece of AI content you have scrolled past this year.
Bookmark this & give it 2 hours, no matter what. It'll be the most productive thing you could do this weekend.
When you hit your step function in earnings/wealth you are not allowed to change your lifestyle for a full 12 months.
This causes dopamine receptors to reset and you'll take a good look at what you actually want.
Rarely do you care much about a car or watch unless insecure
Scott Adams was a real one to the very end. Salute to a good man. Some banger quotes:
- If you spend all your time arguing with people who are nuts, you'll be exhausted and the nuts will still be nuts.
- I used to be stupid but I've turned that situation around 360 degrees.
- You don't have to be a 'person of influence' to be influential. In fact, the most influential people in my life are probably not even aware of the things they've taught me.
- Continuing to believe the same thing, even in the face of new evidence to the contrary, is the definition of insanity - except in politics where it's called leadership.
- I wish I were dumber so I could be more certain about my opinions. It looks fun.
- Remember there's no such thing as a small act of kindness. Every act creates a ripple with no logical end.
- There's nothing more dangerous than a resourceful idiot.
- No matter how smart you are, you spend much of your day being an idiot.
- Remember, freedom is always taken, never given.
- Always remember that as long as other people are gullible, there's no limit to what you can achieve.
- Life is half delicious yogurt, half crap, and your job is to keep the plastic spoon in the yogurt.
@MannCheese2945@paianVII So my idea is to check the food you take in and find products that don’t induce puffy face. I can allow only vegs, cottage cheese, fruits, no wheat products and no sweets. But psychotic eyes is a bonus from personal mission tasks, so thanks guys for aprroving my experience
@MannCheese2945@paianVII Same thing, I’ve noticed when I’m food deprived because of the stress action on life or during fast day my skin starts to glow and face geometry improved because I get rid of standard post-high carb puffs. Two days ago women even hit on me for the first time since I’m bald
