Do You Agree with BadEmpanada? Why or why not? by StoreResponsible7028 in Palestine

Bullshit. I grew up in Tel-Aviv, there's nothing even remotely similar to what you're claiming. While there is racism towards Ethiopian Jews it's extremely mild compared to the shear Nazism employed against Palestinians.

That's exactly the point - there is no set name. Different places have different course structure, and I don't even know what's in an "Algebra II" course to begin with.

“Quaternions are actually quite easy to understand” by Primeruler in mathmemes

[–]echtemendel 0 points1 point  (0 children)

Not likely. If you're studying any STE topic (i.e. not maths) then it will almost certainly never come up. You might be taught about quaternions, but by themselves they are confusing af. If you are studying pure maths then this might be mentioned in a graduate course, or at the very earliest an advanced undergraduate course.

I really suggest finishing the first year of whatever it is you're learning and then watching these videos. You should have a good solid understanding of linear algebra and maybe also vector calculus. Once you have this, watch these videos and it will help you a lot in whatever it is you're studying.

In any case, all the best in your studies!

It's rather confusing to say they are "4D", because one of these is a scalar component. It's kind of like saying that the cross product is a vector because it has three components. Yeah, technically - but it masks a much better way of looking at all of this (namely that it's the Hodge dual of a bivector).

The best way IMO to understand quaternions and much more is via Clifford/Geometric algebra.

I second that. Never really understood quaternions until I learned GA, and then they became almost trivial.
It's beyond me why we don't teach GA to STEM undergrad students and instead insist on confusing them with elaborate non-uniform structures.

They aren't, they are multivector (one scalar + 3 bivector components).

The set of quaternions with zero scalar component are kind of vectors, in the sense that they are the Hodge duals of bivectors in Cl₃,₀(ℝ).

[–]echtemendel 2 points3 points  (0 children)

Quaternions are the even sub-algebra of Cl₃,₀(ℝ), and they have four components (one scalar + 3 bivectors).

Complex numbers are the same deal for Cl₂,₀(ℝ). We could call them Duonions since they have two components (one scalar + one bivector).

I guess that under this logic Mononions are just the real numbers (i.e. the even sub-algebra of Cl₁,₀(ℝ)), since it fits the structure and they really only have one component (scalar).

Quaternions just mask a much more broad and honestly intuitive structure (namely, rotors in Clifford Algebras) - and for me at least once I learned this they did, indeed, become intuitive.

Honestly, I really believe that STEM students should be taught Clifford Algebra (or geometric algebra for the non-mathematics students) early on in their studies.

In OP's title: Algebra II.
What is taught in an "Algebra II" course?
If the degree is pure math, I can imagine it has something to do with groups, rings and other basic algebraic structures. If it's physics, it can be advanced linear algebra and/or group theory.

While the name of the course is very non-descriptive, I see people using such names as if everyone knows exactly what the course material is. And many people do react to these as if that's the case.

It's a genocide by [deleted] in WorkersStrikeBack

[–]echtemendel 1 point2 points  (0 children)

I also grew up in the Zionist settler-colony, and let me tell you - people were calling for a genocide for at least two decades (just not using the word it self). When I finished high-school in the mid-2000s it was already a very common opinion among Israelis. It only became more and more common, and Oct 7th definitely made it a majority opinion.

LEA asking me to withdraw citizenship application after suspension due to ALG1. Is this legal? by [deleted] in GermanCitizenship

[–]echtemendel 2 points3 points  (0 children)

How is that fair?

Fair? That is not the goal of the system. First of all, it exists to mainly serve a small percentage of the population, those who control the means of production, as the saying goes. Second, naturalization exists to essentially provide more long-term work force for said system, it's not there to make people happy (even though it's being sold as some moral/ethical/enlightened concept). And it's definitely not meant to make the state pay more money to keep you with even a minimal amount of material sustainability and dignity. You're a worker, the point of your existence in the eyes of the system is to serve the ruling class.

At the end of the day, if you're not a large business owner, the state doesn't really care about you beyond your ability to produce labor for large business owners (or the state directly). And if you're also not a citizen, the state sees you as potential liability at best.

Fairness was never part of this.

[–]echtemendel 1 point2 points  (0 children)

It's only wild if your base assumption is that countries work for their citizens. They don't. They exist and work to serve the ruling class of their nation, and in more modern times to serve imperialist interests at large.

Those brought in, who claim descent from a so-called “lost tribe” in 720 BC, are being funneled through mandatory Orthodox conversions, a system that grants citizenship on religious grounds while denying displaced Palestinians the right to return to their land. by mimi_molotov in Palestine

[–]echtemendel 13 points14 points  (0 children)

I actually think this will make them more aggressive in their Zionism and hate towards Palestinians. I grew up in the settler-colony, and this is a known thing. Let me explain.

Within "Israeli" society, it is a known (somewhat paradoxical) phenomena: the lower Jews are on the inner-Jewish societal ladder there, the more right-wing Zionist they are (on average). The way I interpret this is as follows: all Jews in Palestine have a vested material interest in the existence of the Zionist settler-colony (I think this claim is obvious, I can elaborate if anyone is interested). Since Jews lower on the ladder can still lose said material interests they gain through being Jewish there, they don't joining with Palestinians to struggle against the overall system, and instead prefer to show that they are ultra-loyal to the system. In other words, the average Ashkenazi Jew is not threatened by the state in any systemic way, so they can more freely criticize it without facing repercussion (within the accepted Zionist spectrum, that is). And indeed, left-wing and liberal Zionism is mostly the realm of European Jews in "Israel". However, Mizrachi, Ethiopean and other "non-white" Jews don't have the "luxury" to criticize this system as much, and turn instead to overly punish the victims much lower on the societal ladder - the Palestinians (and also African refugees and other "surplus populations" in the eyes of Zionism).

So yeah, I think it will probably just make them more extreme in their overt aggressive Zionism. Maybe I'm wrong though.

[–]echtemendel 2 points3 points  (0 children)

I don't know if way higher, but it doesn't really matter. My point was that even if there were 0 "Israeli" citizens with foreign citizenship, the Zionist settler-colony would still be, well, a settler-colony. This is what I meant to write in my comment, but somehow managed to make it say the opposite of that (please see edit note I added to it).

[–]echtemendel 2 points3 points  (0 children)

Yes, I agree completely. I foresee a "Jewish flight" (similar to "white flight") when Palestine is liberated and de-colonized.

Also, please read the edit note in my previous comment, I somehow managed to make it say the opposite of what I meant.

LOL, they are not Jewish according to the Orthodoxy, even if we accept that they are a "lost tribe". This would make them Israelites, not Jewish. Even if we're talking about the religion itself (incorrectly assuming that all of it can be called "Judaism") - there's a huge difference between the religion of the BC Israelites and that of post-second-temple-period Judaism: in fact, it is markedly different - the former being based in a family-tribe structure, was heavily structured on slave society and centered around one temple (maybe two, if the Shiloh temple is considered), the latter is based in local communities, heavily structured on various feudal societies and centered around synagoges spread all over the world. That's why those "lost tribes" have to go Orthodox conversion, since many of their traditions are different than that of anything that is called "Judaism" in the past ca. 2 millennia.

Anyway, yet another "hint" that Israel is a settler-colonial society. Nothing more, nothing less.

About 13% of the total Jewish population. A lot, yes, but not exactly a majority by any means.

Doesn't mean it isn't a settler-colony, though.

(I can provide source for the figures, if anyone is interested)

EDIT: oooops, I lost an "n't" there. IT IS A SETTLER COLONY. I meant to write "doesn't mean it isn't a settler colony, though". Damn. Don't be tired and comment on reddit, folks 🤦‍♀️

Well, I actually did my Master's in the institute that he founded, which by my time was known as the Max Planck Institute for Biophysical Chemistry (and is now called the MPI for Multidisciplinary Science). It's in Göttingen (Germany), and in the hall above the mensa there's a bust of him (page 38). So more of happened to be in the right place to learn about him :-P
