today i asked myself a kid question ”is there an analogue to the pythagorean theorem for triangles on spheres?” 100% driven by kidlike curiosity

with some taylor approximation of the cosine function and with the limit of R to +inf, we get back the ordinary pythagorean theorem! this just makes me happy:)

pictured: an electron, in two chiral components. much more to say about this later! in this visual language, red + green + blue becomes white: a colour singlet. the open eye represents weak isospin “down”; the sunglasses represent a weak-isospin singlet, neither up nor down.

the neutron and proton get a bit complicated, because we get fock space, with sectors, and as far as i understand (i'm not an expert...) in each sector needs to be a colour-singlet.. i'm loving this visual language though!

just posting this as an insurance policy in case openai proves this next year! then i can point towards these, and say: see how i predicted this!

are bosons Λ^2 ℝ^10? it's the adjoint of Spin(10) if i had to guess, it would be that sterile neutrinos exist and constitute dark matter and that Λ^2 ℝ^10 is fully physical

the electron’s mass couples these two components. one particle, two little creatures :) full design (plain is 1st gen, boots = 2nd gen, hats = 3rd gen)

reading the (super interesting!) slides below gave me some ideas for a visual language for each basis vector in Λℂ⁵ bsky.app/profile/john...

​“This is a park area with a working fountain. Naturally, at this time of day, it’s packed with people and children. The weather today brought everyone outside—mothers with toddlers, kids riding bikes—and the strike targeted those exact people.” ​Yurii Yurchenko, chief of the Nova Vodolaha police,

This is horrific. And unsurprisingly the work of a "conservative" multimillionaire. Other adjectives might include creepy, prurient, dictatorial and abusive, not to mention, of course, transphobic.

Nice kitty! 😨 The old 'false saber-tooth cats' are not closely related to the more recent saber-tooth cats like Smilodon, who lived in the New World until almost 8,200 years ago. Between them, there was a mysterious 'cat gap', which has its own Wikipedia page: en.wikipedia.org/wiki/Cat_gap

I can tell a politician's loyalty by those who pay for him to be in power. That's all I need to know. Of course he also voted for the Iraq War. Of course. There is a bit of a correlation between those who voted for Iraq, and those who are willing to represent the world's most corrupt interests.

I feel so much anger towards those responsible for the Sudan War, especially UAE leadership. To deliberately destroy the lives of tens of millions of people, what does that make one?

I made base-1353 encoding, so I can fit 256-bit values, like “96cca2a0c8a3263c74ef36274abf55f410d992034d16e8285811a9ad3fc59c13”, into short 26 character strings, like “ᓒᔳᣏዧᐎᑙᖜዌᙔᐸƫȶƃᒨዊጶᙵኻѫyፐᎉᑫᖫᘪᒩ”. (Also, I think these sigils are beautiful.) johnservil.github.io/sigil/play.h...

nothing to see here, kids.

really a bad look for macron. instead of listening to the eminently reasonable demands of the student protesters, he deploys the military while blaming everyone but himself.

Isn't it astonishing that so much cruelty, evil, sadism, ill will, racism, misogyny, bloodthirst, and narcissism can be concentrated in one man of flesh and blood, Donald John. And if that weren't enough, millions of plebeians and thousands of patricians propulsed him to the seat of imperial power.

The good people of America deserve politicians that stand with the people, against powerful corporate interests, against the military industrial complex, against Isreali lobby firms, and against harmful ideologies and cynicism. They deserve politicians with a good heart who govern well and wisely.

And us, people of the world, deserve better as well. Instead of being held hostage by an evil, demented lunatic who is now siding with the greatest force of evil the 21st century has seen, the KGB agent and wannabe-tsar of all of Russia Vladimir Vladimirovich himself.

As it turns out, the rat infestation of Chicago's Lincoln Park and the corruption of SCOTUS share a common cause in the form of a nonagenarian billionaire who pays people to feed squirrels expensive nuts in Lincoln, thus breeding rats, and paid the federalist society to weaponize SCOTUS

Change is needed. The good people of the USA deserve so much better, so much more love and consideration. They deserve to have a state that looks after them, that wants the best for them, and wants the best for others as well, and does its best to make everyone better off.

All of this needs to stop. How many millions of people need to die at his behest until he is removed from power? His gutting of USAID already killed millions of the world's most vulnerable people. Marco Antonio and Elon Reeve are co-conspirators.

It's like a new Third Reich has emerged, once again allied with Russia, intent on nothing but destruction and cruelty. None of this can stand, him and his movement need to be defeated entirely, peacefully yet firm on restoring justice, starting first of all with restoring the integrity of SCOTUS.
