The Distribution of Prime Numbers: A Geometrical Perspective
https://blog.computationalcomplexity.org/2025/06/the-distribution-of-prime-numbers.html

A colleague recently sent me this blogpost. Some here may appreciate this kind of fun with primes, similar to what I had shared a while back: https://stacker.news/items/755400/r/south_korea_ln by 3Blue1Brown.

> We [introduced](https://arxiv.org/abs/1801.01540) a prime number visualization called **Jacob’s Ladder**. The algorithm plots numbers on a 2D graph that oscillates up and down based on the presence of prime numbers, creating a ladder-like structure. The path ascends or descends based on the primality of subsequent numbers. When a prime number is encountered, the path alters direction, leading to a zig-zag pattern. Number 2 is prime, so it flips and goes down. Now 3 is prime, so the next step changes direction and goes up again, so we move up. But 4 is not a prime, so it continues up, and on it goes.

A nice little video also, further down the article.

This reminds me of Ulam's Spiral - The primes landing on the diagonals in the spiral of the natural numbers. Could give us an alternative to Mersenne primes in terms of hunting for large primes.

The Hijacking of Bitcoin - Brownstone Institute
https://brownstone.org/articles/the-hijacking-of-bitcoin/

Someone in a crypto group I'm part of sent this article yesterday. I stopped reading after this paragraph:

> Lightning works like opening a tab at a bar: you and the bar settle later. It is faster and cheaper for small payments, but it relies on middlemen (called hubs) who hold your money in channels and can see what you are doing. It is not the same as handing someone cash. It adds points where someone else can interfere or shut things down.

When I told him I stopped reading after this uninformed paragraph on the LN, they asked me, _what is LN_? Yet, he based his current negative sentiment on Bitcoin on this article.

This resonates with the article @Darthcoin just posted (https://stacker.news/items/1452620/r/south_korea_ln). This is what we are up against. Willful and/or accidental misinformation campaigns.

The LN works. People are working on making it better, but it works.

Massacre of girls at Minab school: human error or artificial intelligence?
https://en.ilsole24ore.com/art/minab-school-girls-massacre-human-error-or-artificial-intelligence-behind-tomahawk-missile-AIz8iHuB

I already vented about the human side of this massacre here (https://stacker.news/items/1448847/r/south\_korea\_ln), but posting this article as it turns out this could have been influenced by the heave use of AI.

> The preliminary report, according to rumours in the New York Times, reveals that the school was destroyed because Central Command, the military command engaged in the Middle East, relied on outdated intelligence information, provided by the Defense Intelligence Agency (Dia), the Pentagon's intelligence service. And which, inexplicably, was not checked, a procedure that traditionally takes place at several levels and can draw on hundreds of analysts and military experts.

To me, the title is misleading. If it is AI that incorrectly assigned the school to be a military target because of outdated data, then it is *very much* a human error. But then again, as with coding, people don't seem to take responsibility for the code their LLM spawns.

In an ideal world, someone would take responsibility for this shitshow. Yet, this market will likely resolve with a *no*: [https://beta.predyx.com/market/pete-hegseth-out-as-secretary-of-defense-by-march-31-1765112860](https://beta.predyx.com/market/pete-hegseth-out-as-secretary-of-defense-by-march-31-1765112860)

The Obvious Problem That No One Can Agree On - Veritasium

What are you? Please answer the question before getting into the explanation part of the video (starting at 3:32).

https://www.youtube.com/watch?v=Ol18JoeXlVI&t=709s

This is one of the better Veritasium videos I've watched.

I especially like the comments on free will, how to live your life, and rationality.

> Whether we do or don't have free will, you have to live as though it exists.

This resonates with me because in my mid-20s, I entered a (quasi)depressive mindset where, after reading several books touching on this topic, it made me feel like whatever I did, it didn't matter.

I then, at some point, just decided to live by the idea that free will exists, as the alternative was not worth living anymore (and also, it almost alienated a few people around me when I tried to elaborate on those metaphysical ideas).

American forces likely launched strike that hit Iran girls school
https://www.timesofisrael.com/us-probe-said-to-indicate-american-forces-likely-launched-strike-that-hit-iran-girls-school/

> The girls’ school in Minab, in southern Iran, was hit on Saturday during the first day of US and Israeli attacks on the country. Iran’s ambassador to the UN in Geneva, Ali Bahreini, said the strike killed 150 students. Iranian authorities have been the only ones to provide a death count from what would be the deadliest strike of the US-Israeli war against the Islamic Republic. Their figures have not been independently confirmed.

150 kids. This is fucking insane. Supporting any regime that thinks this is normal or acceptable is beyond my understanding. Even if the numbers are exaggerated. @Cje95, you're the most vocal supporter here of the Trump administration. How can you reconcile your support with such blatant civilian casualties?

The Man Who Stole Infinity | Quanta Magazine

> Goos began flipping through, contemplating the letters with the relish of an archaeologist entering a long-lost tomb. Then he reached a particular page and froze. He struggled to catch his breath.


> It wasn’t the handwriting. At this point in his research on Cantor, he’d become accustomed to the strange, nearly indecipherable Gothic script known as kurrentschrift, which Germans used until around 1900.

> It wasn’t the signature. He knew that the German mathematician Richard Dedekind had been a key player in Cantor’s quest to understand infinity and solidify math’s foundations, and that the two had exchanged many letters.

> It was the date: November 30, 1873.

> He’d never seen this letter before. No one had. It was believed to be lost, destroyed in the tumult of World War II or perhaps by Cantor himself.

> This was the letter that had the power to rewrite Cantor’s legacy. The letter that proved once and for all that Cantor’s famous 1874 paper, the one that would go on to reshape all of mathematics, had been an act of plagiarism.

Drama in the world of mathematics~~
