I knew meat could do a lot of things, but I have to say I'm impressed it can produce deli spirits.

people who are forced to vote for Democrats because there aren't better options want commonsense reform: abolishing and prosecuting ICE, salting the ground from which they crawled, and draining the treasury to pay reparations to victims

printing this and putting it on my wall. this is so accurate I have such a hard time believing I've ever done anything right

Meanwhile, every morning for my commute I step onto a metro train that:
- runs every 3 minutes
- carries nearly 1000 people at a time
- is fully electric
- costs €1 / a day for unlimited citywide transit on buses, trams, or trains
- has nearly 100% reliability

Oh, and it has automatic doors. 😇

Making histograms is a common way to estimate the true density distribution of a sample. But how can we choose the number of histogram bins? And if we get fancy and use kernel density estimation (KDE)... Making histograms is a common way to estimate the true density distribution of a sample.

Ever wondered how many bins to choose when making a histogram of data? The answer is that you shouldn't choose a number of bins yourself! ☄️ #astrocode

Here's a little notebook explaining how to make less biased histograms:

At first glance, looks like a Gray–Scott reaction-diffusion

But it’s a fertilized starfish 🥚: proteins self-organizing into spiral waves across the membrane

Same dynamics seen in ❤️/🧠/🌊, even quantum fluids. Universality in action!

Have a look through this gallery to see one of the coolest examples of role specialisation in the insect world 🐜

They live inside twigs with small circular entrances & these workers have evolved heads the perfect shape to block those entrances - effectively, they are living doors!

One of the best-sketched characters in an incredibly character-rich show: a fascist whose (potentially real!) redeeming qualities are continually undercut by his monumental pride, bigotry, entitlement and pettiness

A black and white drawing of three dachshunds arranged vertically, each holding a different optical illusion object in its mouth, and the dogs themselves drawn as if a single line optical illusion. The top dog holds a Penrose triangle, the middle dog holds a Necker cube, and the bottom dog holds a Penrose trident. The dogs’ bodies are elongated in an exaggerated cartoon style. The artwork is signed “@IndieTheIntrovert” in the bottom right corner.

Everyone stop, this is important

It is "fun."

It doesn't matter how despicable a person is, mocking their innate physical appearance is always wrong.

Not because it's cruel to them, but because it perpetuates the harmful idea that innate physical appearance has anything to do with one's character / beliefs / actions.

A three panel comic. In panel 1, two people are facing each other. The first person asks "Hey, do you want to drive really far and spend hours staring at distant, rapidly moving gray-brown objects while trying to find subtle differences between them?" and the second says "No." In panel 2, the first person says "What if they're bird-shaped?" and the second person says "Then absolutely, yes." In panel 3, the two people are standing and looking through binoculars at distant shorebirds on a beach. The first person says "Yay shorebirds season!" and the second says "Woo!"

It's that time again :>

people more pro-AI than me? gullible nerds. people more anti-AI than me? fear-addled clowns. and me? perfect, as per usual

one of the most heartbreaking things i have learned in my career as an educator is that our country's disinvestment in children is not just neglect -- it crosses over to antipathy

It’s worse than “Gaza is being starved and destroyed and no one cares.” It’s that hundreds of millions *do* care and are powerless to stop it. We need a world where that can never happen, where the masses actually have political power.

How far can you compress a complex system?

🚨 In our latest paper we collapse high-dim compartmental models (from epidemics to ecosystems) into a single 1-D equation using quantum-inspired math, exposing universal phase transitions #ComplexSystems ‪👇👇👇

When using computer vision to identify organisms in a image, it helps to know what the model was trained on. To a shark ID AI, everything is a shark.

some kind of flow chart of mathematicians and theorems in non-metrizable manifold theory

diagrams of weird non-paracompact manifolds decorate the boundary; a terrifying and impenetrable Venn diagram inhabits the middle

words cannot capture how busy and overlapping this diagram is

What if a diagram contained multiple periodic table-ish things and a bunch of beach balls and there's one spot near the middle of the figure that says "10 big eggs".

Just discovered the motherlode of wildly incomprehensible unhinged mathematical diagrams.
