I'm a college dropout in burgerland, and I would like to improve my understanding of math, which was my worst subject in academia. Does anyone here have any suggestions or resources for someone who only speaks English, but would still like to do better than American schooling? Assume that I stopped learning math in 6th grade, or 9th grade for geometry in particular.

Here's how I proceeded in Mathematics. I was a Biology major with a minor in Chemistry:

Geometry
Algebra
Algebra II
Trigonometry
Pre Calculus
Calculus I
Calculus II
Linear Algebra
Calculus III

All can be learned at the Kahn Academy.
And you can find problems online.

We already have a math thread.
I study chemical engineering, so I have the luck of going through a somewhat decent education in mathematics. So our focus lays in linear algebra, differential equations, fourier, laplace etc. I don't know how this will help you if you want a more allround education in math

4/sci/ has a good list if you want to learn about math like an autodictat

Where do most communists stand on the being vs becoming vs nothingness metaphysical debate? This debate is as old as philosophy itself; does a left wing mindset require you to take a particular stance, or is it irrelevant?

I would say from the perspective of Marx commies are basically forced to rest on the "becoming" camp.
>>

 No.6059

Thanks to Marx's Hegelian lineage,you can certainly see a strong influence for the becoming side of things - but this seems like more of an accidental than a necessary relationship. It's very difficult for me to think of an argument about metaphysics that would change my politics, or visa-versa. (Everyone's favorite right-wing syphilitic crank, Nietzsche, was no less of a becoming enjoyer.)

There's a certain sense in which leftists need to believe that things in the social world are capable of change, rather than simply given in their behavior through an unchanging nature. But that's pretty divorced from metaphysics - certainly it's nothing that someone with an eternalist outlook on the metaphysics of time couldn't translate to their own language (that is, that different parts of the eternal 4D universe look different along the time axis just like they look different along some spatial axis.)

If you know the original language well, read it in the original language. (And certainly no shortage of good theory in German!) If not, well, the translator probably knows the language better than you. I learned this the hard way, trying to ploddingly get my way through Baudrillard and Badiou in French (which I can read, but slowly and not very well) rather than just going for the translation.

>"With Steve Kotkin […] he doesn't take the earlier period that seriously. Montefiore who DOES look at the early Stalin (he has a book called Young Stalin) in fact DOESN'T take Marxism, the 'National Question' seriously—One time I met Montefiore and he said, "What are you interested in?" I said, "Well I'm interested in the Revolution, the labor movement; I'm interested in, yknow, social democracy" and he said, "Oh good! I'm interested in his women." So if you're interested in his women, then go to Montefiore and you'll find a Stalin who's not only a bandit, a gangster, a terrorist, but a pedophile. I took Stalin very seriously; I took Marxism very seriously. He was a journalist for much of his career! He wrote dozens and dozens of articles in Georgian and in Russian—and he wrote on the 'National Question' […] So it's a lot of context—maybe too much context."

So is the universe flat or is it curved? I haven't had the change to read the whole paper, yet, but, from what I understand from the paper and what the lovely people at PBS explained to me is, apparently physicists at Cornell University observed a cluster galaxies under extreme gravitation forces causing gravitational lensing. Now this is nothing spectacular as far as what observation about the universe has lead us to, but, what is interesting is that when the amplitude of light passing over these distortions in gravity are examined more closely, apparently, they fall way out of line with currently, standard, models involving the geometry of the universe which uses triangulation of areas in the Microwave Background Image and Early Super Nova in the Early universe to summize that the universe is flat. This totally flies in the face of our current understanding of the universe and could have damning implications for modern Cosmology; The universe wont expand for ever? What is driving expansion then? Our models for Dark Energy break down. I am literally freaking the fuck out over this right now. HELP ME EDU!

>Appearing quarterly since 1936, Science & Society is the longest continuously published journal of Marxist scholarship, in any language, in the world.


>Science & Society is a peer-reviewed interdisciplinary journal of Marxist scholarship. It publishes original studies in political economy and the economic analysis of contemporary societies; social and political theory; philosophy and methodology of the natural and social sciences; history, labor, ethnic and women's studies; aesthetics, literature and the arts. We especially welcome theoretical and applied research that both breaks new ground in a specific discipline, and is intelligible and useful to non-specialists.


>Science & Society does not adhere to any particular school of contemporary Marxist discussion, and does not attempt to define precise boundaries for Marxism. It does encourage respectful attention to the entire Marxist tradition, as well as to cutting-edge tools and concepts from the present-day social science literatures.

The other day in the China thread, I read an argument about supporting China over Vietnam despite the latter's arguably more "socialist" economy. The reason for support of China over Vietnam would be the fact that the former is most poised in breaking with the established American world order, while the latter is more inclined to appease American interests due to strained relations with the PRC.

All that's well and good, but these (nonetheless relevant) geopolitical considerations made me wonder how to study historical and current AES countries' political economies, their evolution, and how they stack up to, for example, western social democracies such as the Nordic countries in their heyday. Again, usually I'd be foaming at the mouth too seeing a comparison of Scandinavia with the late USSR, but from a purely economic standpoint it'd be nice to clear up some of the confusion.

This becomes especially interesting, once again, when bringing up modern-day China. Is it socialist? Is it just social democracy at the barrel of a gun? I feel like it's difficult nowadays to get a purely economic view of that question without involving, again, the matter of nigh obligation to critically support China due to their geopolitical position. Let's change that and drop some PDFs.

Let's have a thread about chemistry. I can't be the only amateur chemist on here. To please the mods, everything in here is purely academic. Check local laws before you embark on your projects. And before you do anything, make sure you have appropriate safety equipment. Think about the worst thing that could happen to your reaction, because chances are it will. Don't be stupid.

I've been experimenting with ways of concentrating acetic acid. pic related is 4 ml ~66% AcOH by weight based on it being liquid at -20°C. freeze distillation worked best for this, but the yield isn't great: 4%

I tried simple distillation too, and despite AcOH and H2O not forming any azeotrope I didn't see much improvement over the 24% white vinegar I started with. it also formed copper acetate in my condenser, which I should have thought about tbh

next step is trying to drive off the water by mixing in IPA and distilling off the IPA+water mix (and resulting isopropyl acetate). molecular sieves would probably work better, but I don' have any
>>

>>5960
I forgot my freeze distillation method:

1) cool your white vinegar down enough to where it becomes a slurry and filter it until you get maybe 1/3 of the initial volume
2) put the mixture in a jar and stand it upright in a freezer
3) once the mixture has frozen, tip the jar over and let it sit in the freezer like that for a day
4) a small pool of liquid should have formed, separate from the frozen fraction. pour that off into a separate container

the concentration of the final fraction depends on the temperature in the freezer. the temperature must be above -26.7°C for this to work.
