> This is a silly argument. My main argument was that the OP's supposedly clear-cut genetic category was not defined. You also seem to be saying that it's not clear-cut and defined. So why are you saying that my argument is

Consider this: We do not, in fact, have to define something. We don't have to define an artificial genetic category just so we can then categorize people into artificial genetic buckets.

You're right! To the Romans, every Roman citizen was a Roman. There was no "genetically Roman" category. The OP's "genetic" category is indeed a "made up concept", as you say! And the reason they made

None of these statements are meaningful without a definition on your part of what it means to be "Ancient Roman" in a genetic sense. Do you mean, say, a handful of villagers living in the area of today's Rome on 21 April 753

There's almost no original art in Pompeii, it's all in the archeological museum in Naples. There are some reproductions in place in Pompeii, but mostly it's bare brick walls that the art has been scraped from. You need to see

250 years is longer than the existence of a country called Italy, let alone the Italian Republic. Just like in Italy, the history of people in your area did not start with the founding of your country.

If you're interested in actual linear algebra with diagrams, I think https://graphicallinearalgebra.net/ is the thing to look at.

You are praising Lean for optional verification. They want to add optional verification to OCaml. Where do you see an impedance mismatch? Just in the fact that you don't find OCaml pretty enough?

Why are you using phrasing that equates AI and humans? Codex isn't in a position to decide whether to do work.

Most Prolog code on the Web is complete garbage.

No. In this type of language, the typical division function does not check against zero. It has a precondition that requires the caller to ensure that the divisor is not zero. If the data the caller has is completely arbitrary, then yes

I'd like that. But this system is very attractive for the strongest party, so it will be a real test of their commitment to actually representative, multi-party democracy. Also, the general system (a mix of single-member constituencies

Also, the fact of faking a terror attack and everybody just shrugging it off as an obvious Russian false flag op. I think even Orbán understood at that point that the jig was up.

It's worth noting that the party vote share here was 53% for Tisza vs. 44% for the even-more-right-wing parties. The fact that this results in a two thirds majority is because the electoral system inflates the strongest party. Orbán ha

Oooh, bikeshedding! To me your `import math with x as y` reads like "import all of math, making all of its symbols visible, just renaming some of them". That's different from the intended "from math, import only x (may

This is someone's private project for their own amusement. It's clearly not in a state where it would be "useful" to "users". Nor is it meant to be. At the moment it's meant for compiler geeks to look at.

Gotcha. I've never had a problem with this usage. I guess I see the objection of "the goal is to prove the theorem" vs. "the (initial) goal is the theorem". It strikes me as overly pedantic, but we're talking

Maybe you could show a simple example so the OP can get an idea if that is what they are looking for.

Nitpick, but it's a bit strange to say that the two_eq_two theorem looks like a function. It looks more like a constant, since it has no arguments. (Yes I know that constants are nullary functions.) I would find the following a more co

Rocq used to have a "mathematical proof language". It's hard to find examples, but this shows the flavor ( https://stackoverflow.com/a/40739190 ): Lemma foo: forall b: bool, b = true -> (if

Yes, there is a prelude that defines natural numbers and an addition function on them. As the post notes, the reflexivity tactic "unfolds" the addition, meaning that it applies the addition function to the constants it is given, t

I can, yes. Laypeople might not be able to, or be aware of the various (equivalent) accepted definitions. And yes, this means that many laypeople are not effective at doing mathematics. Does this surprise you? If yes, then the linked articl

If the parser's rejection of an address doesn't influence the site's behavior, the site might as well not use the parser.
