This is why every year we remember our honored dead by entering their sacred passwords so they will never be truly gone.

Maybe the people of that region put South at the top of their maps now.

I like the last one, because often I'm *not* there when it happens, but I don't need the rest.

Not many cryptids can say they punched out a guy at the Council of Nicaea.

It's true, they are closed and have no isolated points.

e+π … I guess.

Yeah, that number's obviously fake.

But to a set theorist, a real number is just a set of natural numbers, and a formula (in the sense of logic) is just a natural number, so that's how this set of formulas is a real number.

There are some states whose administrations would just go along with this because Trump said so, but Colorado isn't one of them.

This is so out of touch. Would you be OK with losing access to expensive things that you don't have access to now? Yes, I guess so!

Yes, Washington and Jefferson knew that slavery was wrong and decided to keep doing it anyway, while Trump can't imagine what they were so conflicted about.

That and the racism.

This explains why Asia is legally considered part of Italy, which otherwise makes no sense.

Trump has always been simultaneously friendly towards Russia and hostile towards Russia's client states, such as Syria, Iran, and Venezuela. My diagnosis is that he doesn't know anything about international politics but is just attracted to whoever is in charge; which is Putin, not the clients.

Hopefully not by bigots.

Obviously this is a bit much, but I do tell kids how Santa Claus punched out a guy at the Council of Nicaea.

(Which isn't really true, but it's not really true that he rides in a sleigh carried by eight reindeer either, so 🤷)

I honestly surprised that it's even an option!
December 10, 2025 at 7:21 PM
Good!
