 Good morning, John. A couple of weeks ago, somebody mentioned me in the comments of this TikTok. I was just doing my makeup for work, and I just wanted to tell you guys about how I don't think math is real. And I know that, like, it's real, because we all, like, learn it in school or whatever. But who came up with this concept? And you're like, Pythagoras! But how? How did he come up with this? How would you even figure that out? How would you, like, start on the concept of algebra? I was immediately excited by this because this young woman is asking all of the right questions to not just lead to a greater understanding of math, but actually joyous understanding of math. And I get frustrated that oftentimes the way we teach math right now ignores these questions. How did Pythagoras, a dude who didn't have a flushable toilet, figure out an equation that we still use and is still useful today, thousands of years later? A truth so true that it is more true than reality is. Every point in our universe has some bluntness. Every line has some wiggle. But in Pythagoras' mind, there was a perfect triangle, one that no matter how far you zoomed in, the lines were straight, the points were pointy. One in which, for every right triangle, the area of the square made by the hypotenuse was exactly the same as the area of the squares made by the legs of the two triangles added together. Exactly! Exactly! Now there's the question of how he figured this out. There's a number of thoughts about this. We're not sure the one that's most discussed is that he was looking at a bunch of square tiles and he thought if I split one of those squares diagonally, then I get a triangle. And the legs of that triangle, well the squares made by them are right there. They're those squares there. And the square made by the hypotenuse, well it's made out of triangles if I split these other squares. But if you add those triangles we just made up, you get the two leg squares. And then he abstracted that not just to triangles made by squares, but all kinds of right triangles. The point though is that he didn't need any special knowledge to figure this out. He didn't need any special technology. He just needed to play a game in his mind. They say he was like visiting a palace. I think he was pooping. I think 90% chance he was pooping. Now the Pythagorean theorem is useful information, like it comes in handy for people. It doesn't come in handy for me. That's not why it's interesting. It's interesting because it's interesting. The idea that we teach people the Pythagorean theorem without teaching them that mathematicians build universes in their minds that are more perfect than the one that we live in in some ways, that's wild. That's wild. Sometimes it is brought up and sometimes the fact that Pythagoras built a cult promising secret knowledge about this stuff and then actually delivered on that secret knowledge that was extremely powerful and wild that you can create a universe in your mind. That also is sometimes taught, but not always. I mean, come on. This young woman asks, does math exist? I don't know. I don't know. The Pythagoras discover his theorem or did he invent it? Does math both exist and not exist? Is it an artifact of our minds or of reality? No one knows the answer to that question. Well, let people ask it. The most discouraging thing is that, of course, because as discussed, this is an imperfect universe, people then mocked her as if she was stupid when she's asking the big questions. Math is a game. It's a game we play in our minds. And I don't know how we ended up going from like, go play, go play. To like, remember this equation. This is how we will judge you when we're deciding whether or not you get to go to college. So bless this young woman for her questions. And bless kind the drag queen for explaining mathematics on TikTok. So I guess this universe does have some things going for it. John, I'll see you on Tuesday. Also, I interviewed Bill Gates about misinformation and internet platforms over on Hank's channel. If you want to check that out, it's there. I liked it.
