All good communists study math.

What are you studying right now? What is your favorite field of mathematics and why?

Personally, I really like the book "Linear Algebra Done Right" by Sheldon Axler. It is on Libgen if you are interested and I attached a pdf.

for you

I’m taking differential equations and my textbook is useless as fuck. is there an accessible alternative that has more example problems?


Do you happen to know any good courses online or whatever on discrete math? I found it pretty interesting but my professor was NOT GOOD at explaining the material and since COVID happened we kind of rushed through the class so I left feeling like I didn't entirely understand all of it


Can any mathsanon explain to me how to actually understand math? Because I just don't seem to master the tasks, that require you to truly understand the Essence of Maths. The only way I solve those Tasks, is when I look at the Solutions and this can't be the Point though, am I right?.

You do it every day and at some unknown point it just becomes an extension of your mind. The essence can only come from solving problems, usually with other people to get different perspectives, and creating a set of skills which you can call upon to solve problems.

I remember in middle school trying to desperately remember which axis is the x and the y, and how linear equations work. However these attempts are actually counterproductive IMO. At a certain points of maths you let go of trying to 'get' it, and just move on, then after solving future problems it may come to you.


lads, I'm looking for books in pdf or epub format on the CIA and the Mossad, specifically pic related. Drop any you have, or rec

and how do they plan on deprecating money itself? I know labor vouchers is usually the system that’s brought up but it doesn’t seem like Marx himself was thrilled about it, he just said it could be temporarily used in a workers’ state. I don’t understand how he planned on deprecating it afterwards. Cockshott expanded upon this by adding that they could be digital so that people wouldn’t be able to trade with them. but how does the act of trading currency inherently promote labor alienation? I understand how under private property it does, but in a collectively owned means of production I don’t see why it’s a problem, or why it’s any better than the currency system of the Soviet Union.
tl;dr why do orthodox Marxists believe no banknotes at all > labor vouchers > money?
pic unrelated.

>why do orthodox Marxists want to eventually abolish money
here is a video about thermodynamics of money https://www.youtube.com/watch?v=BQrEEdy_uwM
summary of the video: money causes extreme inequality and it's deterministic.
>he just said it could be temporarily used in a workers’ state. I don’t understand how he planned on deprecating it afterwards.
people will work less and less because of higher and higher productivity, eventually every good will be too cheap to put a price on it.

It will not make sense to put a price tag on the earl grey tea that has just materialised from thin air in the replicator hole in the wall, because it only contains a few milliseconds of labour time, and any economic interaction would take you a few seconds to complete. Basically the time-cost of transactions would cost hundreds or thousands of times more than the products you get. It would be like going to a restaurant and ordering a cup of tea that cost 0.05 money for the tea but 100 money for the credit-card transaction.


I get that automation significantly reduces the labor time necessary to produce a commodity, but won’t a few job sectors like construction, resource extraction like mining, wholesale and retail distribution always add a significant number of hours of labor time per person to the commodity? some of these could theoretically take over 1000 years before they’re automated to the point of demanding nothing but seconds of time, am I wrong?


>I get that automation significantly reduces the labor time necessary to produce a commodity
It's not only about the cost of a commodity. Transactions are not free, you have to spend time interacting with a transaction system like money tokens, credit cards and labour vouchers too. You have to spend mental energy to decide on purchases. At some point the hole of humanity would spend more time and effort on transactions than they work in the economy it self. It just becomes overhead.
>but won’t a few job sectors like construction, resource extraction like mining, wholesale and retail distribution always add a significant number of hours of labor time per person to the commodity?
I don't really know how the future looks like but replicators don't have much in terms of externalities, they need power, and maybe once in a while you need to refill the matter cartridge because it doesn't perfectly recycle. The replicator is just a projection of observable trends, like productivity improving, and shrinking of the size of production tools relative to the products they make, and it's the ultimate multi tool, because in principle it could do any modification you want. I don't really know what people will do, basically all the constrains we have today would be removed. If i want to make a prediction i'm left with few indicators, but there definitely is a lower cut-off point where prices make no sense to humans. And that's what i'm basing this on.


Post-scarcity doesn't even imply 100% automation.


USSR was moneyless for all that maters. Money is power to command labour. USSR's currency didn't have any such power.

Has anyone read it? What do you think of its attempt at refuting marxism, its socioeconomic analysis, and Hegelian logic?

I've been working for a manifesto all these days I've been trying to idealize the Khmer rouge ideology which was hardly based on radical nationalism and Maoism and apparently I call my ideology national Maoism.
Therefore I'm searching for the mao Zedong national liberation or KR politics later I would publish my book on amazon kindle.
Still, there is a reel version of my book but sadly I wont reveal it only few had the chance


>Pol Pot




Soo how it's going?


>book about Pol Pot though
>will publish it on Kindle

Hahaha you absolute fucking Schizo. You have my blessings

This is a thread for communists who are (or are planning to) study at [b]unnamed[/b] universities the world over.

The thread is to serve as a mutual intellectual support system and meta-discussion for communist students to
· share resources for picking and learning your object of study
· discuss strategies for studies
· weekly rhythms and scheduling outside of the classroom
· organizing the student-body and/or spreading artistic agitation
· all while ultimately staying safe and completing your studies

How easy would it be going to uni in China? As a non-native, of course.


In philosophy you can insert your pet issue into any paper if you try hard enough, like woman do with feminism lately.


Where can I read more about this?


If one knows Chinese and scores highly one can go to some good public STEM universities. Technically most people have done English classes in earlier but obviously that doesn't mean they can fluently speak the language. Getting to know the city before enrolling is a good idea too.

Don't act too entryist, though, because orgs justifiably don't tolerate that activity.


Also, unless they already are favorable to Marxism and Communism, it's probably better to start off with revolutionary works that are more relevant to the orgs' issues. Social justice is a part of any communist program, and it shouldn't be too hard to find material that's related.

Just gauging interest in a loosely organized Capital Reading Group. Not sure if a reading group has been done on here but we could agree to read a few chapters a week and then create a thread to discuss it or alternatively make a group signal/matrix for it. If there is no interest then please Sage or Ignore.

ideally i want this to dove tail into Vol 3, I also don't have the bandwidth to host another Vol 1 reading group unless someone wants to take that torch i dont mean to imply I'm doing really anything more than reading the chapters and participating in discussion


I can't join. It says "no known servers"






This week we are reading chapters 11-14, and we will be dividing chapter 15 over the 2 weeks after.

This may change with holidays but the plan is to start Part 5 after the new year.

I consider myself fairly intelligent when it comes to reading papers, but I'm really struggling with this one.

This paper is about an education program in Indonesia and the long term effects on the job market. I'm used to studying more sociological papers, but this also includes lots of statistical analysis and words like function and regression that I don't understand.

Also, I've read this passage 10 times and don't understand it

>The production function in the formal sector exhibits constant returns to physical and human capital combined. The fact that the increase in the share of educated workers led to a movement of workers from the informal to the formal sector indicates that the elasticity of substitution between labor and land in the informal sector is smaller than the elasticity of substitution between labor and capital in the formal sector.

Can anyone help me? If I want to understand this stuff, what kind of courses should I be looking at?


I'm not a student but I read shit like that occasionally. The author is not making up a private jargon. The language is utterly generic econ stuff. So I don't understand how you can fail to understand it. You can and should just look up the terms you don't understand.

Elasticity in economics means flexibility. If chocolate pudding varies a lot in price but I keep on buying the same physical amount month after month, then talking in Economese one would say that my demand for chocolate pudding is inelastic. Inelastic substitution between two things just means that having more of thing X does not help much with a lack of thing Y. (It's common in contemporary economics to not assume a general substitution rate like 5 X make up for 2 Y no matter how many units you have of each, rather it is usually assumed that the ability of the things to work as substitutes for each other gets worse the more you get away from the current proportions. This is not empirically derived, but based on the optimistic assumption that we are close to acting in a very sensible way about things like that.)

Constant returns means that when you are cooking something and you multiply the amount of each ingredient by the same number, the output of what you are cooking also gets multiplied by the same number. If at least one of your inputs cannot be varied like you'd want to, economists usually assume that you can't have constant returns. This is obvious in the cooking example if you really rigorously just follow one recipe with no alternative inputs allowed. Economists usually assume that you can do some substitution still, so you still have bigger output than before, but the growth is less than proportional to the inputs that you multiplied, since you didn't multiply everything. Again, the regular assumption is that prior to your attempt at changing the output quantity you had sensible proportions.


>The author is not making up a private jargon

I never said they were. I said that I needed help understanding it.

Thanks for the explanation.The problem with looking stuff up on google is that they rarely give a direct answer.


For understanding neoclassical economics - which in turn is necessary to learning contemporary heterodox economics, because so much of the jargon is shared - https://www.core-econ.org/ may be useful. It's free, designed for students, and by mainstream econ standards avoids a lot of ideological mystification.


Sorry, I read your exaplantion, thanks for assisting, but I still can't wrap my head around this idea, I think I'm starting to get it…

> the elasticity of substitution between labor and land in the informal sector is smaller than the elasticity of substitution between labor and capital in the formal sector.

by saying the elasticity of substitution between labor and land is relatively low, does this mean that because land is relatively fixed, we cannot simply import many workers to match the productivity, because at a certain point, we need the land to work on?

And then on the other hand, in the formal sector, the elasticity of substitution between labour and capital is relatively higher, because you can substitute labour (i.e. people) for capital (and vice versa, i'm not sure if this is implied to go both ways or not??), and still maintain productivity? So are we saying that the formal sector is more equipped to deal with influxes of workers (or in Marxist terms, variable capital)?


Yes. Where the author speaks of capital in the formal sector, he is thinking mostly of machinery and he is assuming that when the conditions of business change in the formal sector it's not that hard to change the mix of people and machinery to get something close to an optimal mix, unlike with land.

How should I go around teaching a kid a new language?
2 posts omitted. Click reply to view.


Sorry for the delay, thanks a lot for this material.




the best way to taech a kid a language is to speak it around them at home


Thanks comrade. i am a esl kindergarten teacher and i really really need theory. My school has me essentially coming up with my own cirriculum.

Is there any resources you could point me to on education theory ideally around:
Kindergarten and child development
english as a second language.

I am fucking drowning here so literally anything you can send me helps enormously


Also anything to do with cirriculum creation. I'm reading a book called "how we learn" which is pretty obvious what its about, but it's taught me about spacing and the study test study cycle and what spacing tests are best at retaining knowledge at.

My problem has been that i don't really know what areas of speech i should focus on. Should i teach them verbs and create stories around that that incorporates the target language? should i teach them common sentences? "how old are you? how are you?" etc I don't know if i'm actually teaching the kids anything. I mean i see them pick up some shit but i dunno mang.
sorry babbling. but yeah, i could really use some help

Everyone tells me Penguin Classic's translation of all of Capital is the best around but what about the rest?

- Paris Manuscripts
- Germany Ideology
- Civil war in France
- Feuerbach
- Gotha
- Grundrisse
- Wage labor and capital

Get whatever tbh.


Just learn German


Not an anglo so learning german would be pretty hard for me.


>Not an anglo
what's your native language then, anon? maybe if you tell us that we can give you recs based on your native lang and then you can look for those editions. I always prefer to read in my native language, even if I'm pretty confident in my english.
