[Valeriy M., PhD, MBA, CQF @predict_addict]

I saw a guy studying math in Starbucks today.

Table: one book.
Tools: a pen and a stack of paper.

He wrote down a problem.

Then just… stared at it.

Five minutes.
Ten minutes.
Twenty minutes.

Like a psychopath.

No laptop.
No ChatGPT.
No YouTube “calculus in 10 minutes.”

Just a page full of symbols and a guy thinking.

Then he crossed everything out.

Started again.

More symbols.
More scratching on paper.
More staring into space like he was trying to summon Euler.

An hour later he had solved one problem.

One.

Meanwhile the guy next to him refreshed his email 27 times and watched two productivity videos.

Funny thing about math.

The people who look the least busy
are usually the ones actually doing the hardest work.

We rave about giants like Newton, Einstein, Bohr, Tesla, and Edison. But in terms of direct impact on our lives in the information age, nobody comes close to Claude Shannon.

In 1948, he dropped a straight 10/10 paper:

A Mathematical Theory of Communication.

His work has imbued us with the ability to send whispers across continents.
The paper doesn’t just suggest techniques, it draws the boundaries of reality for information... how far compression can go (entropy), the maximum rate a noisy channel can carry reliably (capacity), and why error correction isn’t optional if you want those whispers to arrive intact.

I think we should really re-label "philosophy of physics" to be under "natural philosophy"

Probably the same goes to "philosophy of biology"

🚨 BREAKING: Someone just made 70B parameter models run on a single 4GB GPU.

It's called AirLLM. No quantization. No distillation. No pruning. Just raw 70B inference on hardware that costs less than a dinner.

You can even run Llama 3.1 405B on 8GB VRAM.

Here's how it works:

→ Decomposes the model layer-by-layer
→ Loads only one layer into GPU memory at a time
→ Runs inference, moves to the next layer
→ Prefetches the next layer while computing the current one
→ Supports 4-bit and 8-bit compression for 3x speed boost

No cloud API. No $10K GPU. Just pip install airllm and go.

Here's the wildest part:

It supports almost every major model — Llama, Qwen, Mistral, ChatGLM, Baichuan, InternLM — and it auto-detects the model type. One line of code to load. One line to generate.

Works on Linux, macOS (Apple Silicon), and even Google Colab free tier.

Your old gaming laptop can now run the same models that needed an A100.

My favorite books to self study pure math!!

When I was in undergrad, I spent a lot of time self-studying pure math. But I wasted a lot of time because I didn't have a roadmap.

So here's a list of my favorite books, videos, and problem sets that you can use to self-study many of the key topics in undergrad-level math: a 🧵 1/n

The story of modern techno-capitalism seems to me to be the story of converting luxuries into necessities by building systems and infrastructure around them
