This looks like a Body Worlds work by Gunther von Hagens. I had the opportunity to meet him once at a conference. I worked in a plastination lab and the other staff there all had stories about how he imported in cadavers that had really questionable origins. One example is a cadaver with peculiar tattoos on it that turned out to be common soldier tattoos in the Russian military, except that the cadaver's documentation had nothing to do with Russia or Europe at all. And one of the Body Worlds exhibit is a pregnant woman with fetus in the womb. von Hagens claims to have received permission from the woman to plastinate her and the womb in case of her death. Pic related. von Hagens also has a proprietary method of plastinating heart vessels that the lab I worked at had tried to replicate for years.

Are really going to stop them from using it if the results of the integration are the same thing? It's the only reason they are using it for, they don't give a fuck if it's measurable or not, because it always is, and you don't need to formalize a lot to be able to understand that the integral of x concentrated at a single point is x itself

No, he didn't.
In general every "reasonably" integrable function has a distribution as a derivative, in some cases the derivative isn't just a distribution, but also a measure (see the dirac measure, which is the derivative of the signum function) and sometimes it isn't just a measure but also a function, e.g. take the derivative of the absolute value.

But it literally does not, it's handwaving and even worse misleading handwaving.

There is a perfectly rigorous and arguably much more intuitive way to understand it.

>they don't give a fuck if it's measurable or not
What the fuck does that even mean? What is supposed to be "measurable"?

>you don't need to formalize a lot to be able to understand that the integral of x concentrated at a single point is x itself
Exactly. The slightest amount of measure theory will show exactly why it works that way.

This is true, as long as the taylor series exist (the function is C^infinity). Perhaps anon meant that the radius of convergence at every point is 0, meaning the center of the series is the only point it converges on.

cant you just use a different type of triangle approximation at the closures such that all the x are in the domain? is this what you mean they do "at the boundary"?

Sorry, should've been more clear. I mean like having a domain of [-pi, pi] and then doing a derivative of, say, a sine at sin(pi).
For a derivative to be defined you need a ball around the point where you want to take it that you can arbitrarily shrink, so that you'll get a unique number. That's not possible in boundaries.

no quite alright, looks like i guessed your point more or less right the first time. As you can see i suggested shifting the triangle to have its outermost point be the closure of the set. im sure you have some clever reason this isnt valid but here you are.

All of quantum field theory. Time independent perturbative expansions are not actually Taylor series (even though a lot of retard physicists think every power series is a Taylor series), but asymptotic series that converge nowhere. This means that "greatest accomplishment of modern theoretical physics", where the measured value of the electron g factor was determined to match the theoretical one to oodles of decimal places, was pure dumb luck. The series expansion they used to determine it does not converge and the terms eventually increase without bound. There has been no attempt to actually rigorously determine good error bounds on these things. Somehow it still works, even though it's all but guaranteed not to. My money's on all of QFT being a fluke.

Is that really true? My QFT days are long over, but isn't electromagnetic coupling weak, and the expansion coefficient << 1 (1/137?)? Anyway, still a remarkable result. Not just because of the convergence (or lack thereof) of the series, but all the shit you kick aside, regularization and renormalization, and it still comes out on top.

there's a reason why there's a millenium problem related to QFT, it's an easy problem to formalize mathematically
but it probably wasn't a fluke; many times has physical intuition led physicist to correct conclusions with incorrect mathematical assumptions, that turned out to be equivalent to the correct formalized counterparty. most of quantum mechanics, basically.

Yeah, James Grime and Matt Parker have both been accused of child molestation while they were teaching in high-schools in England and Australia respectively. Matt Parker moved to England to avoid persecution and the charges agianst James were dropped (after reaching a settlement with the family not publicly disclosed). I think there is also a photo of both of them with Jeffrey Epstein on his island. There are roumors they had acquainted each other before and James suggested to Matt to move to establish their number-pedo ring in England, which (according to the rumors) operates to this day. The case has been scilenced though and the police seem unwilling to investigate further.

All the boomer chemistry professors usually tell how they how they used to "prank" with making some nitrogen triiodide and pouring in a hallway or smth, so when someone steps on it it goes like bop with a purple cloud and they laugh their asses off, cuz they scared the victim.

Doesnt he have a PhD and degrees and spent decades in these 'training systems' as a classmate?

I resent that quote. Is he implying that he is immune to propaganda and indoctrination despite that no one can be? He buried himself while keeping a smug attitude about it. Disdainful. Also, wouldn't he have retired from the 'training system' out of disgust? Seems like virtue signalling the more I think about it.

>>11620630
He isn't. I read his writing, including his posts on quora which I used before reddit before 4chan up until a couple years ago when I was a leftist. It really pales in comparison to any other author's, even though I really wanted to like it. He isn't smarter than a low-grade PhD professor.

You see, I followed more than a few non-STEM PhD proffesors apart from Chomsky over there in Quora and over months I realized that, despite their really well written and insightful and interesting answers, they were empty at their core. Let me elaborate.

They personified what Chomsky implied in the pic of >>11621837, especially on topics in which they are emotionally invested. I strongly believe their extensive knowledge and experience are only useful insofar they consider the other side on the same level and validity as their hypotheses and not as an enemy to disprove. Yet it is palpable they don't.

I cannot just put in simple terms how important I consider it. Yet; Quora, much of Academia and Chomsky himself share the position that no *legitimate* author or scholar of the retractors of these emotionally invested topics (such as IQ and sexual dimorphism) exist in any way whatsoever, thus, should not be read or taken seriously. As Chomsky's quote said.
How can they make any conclusion worth a shit? I promptly left.
A pity. I also had the misfortune of meeting some irl in my studies. Ironic and fortunately that backfired on me by pure Streisand.

>tl;dr I agree with that quote but makes me resent him, also I don't consider Chomsky smart.
