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.

> The Nazis and killers were punished, but many were rehabilitated. It's a complex ethical and moral question which most people frankly do not want to go into because it is so much easier to say "fascists are subhumans to be killed" rather than to try and stop and save these deluded people.

Reading as I play Wolfenstein. It’s funny, because in this last level I’m trying to beat General Deathshead is trying to guilt B.J.Blaskowics over the families of the Nazis he has killed. Sardonically, it’s noted he must have killed thousands!

Ok anon, but fact of the matter is, the resources and bandwidth needed to save and reform any of these people aren't available on the left, or will be in a very long time. For that reason, we can't let the humanity of these people interfere with our goals, even if recognize these things to be true. I am for crushing the fascist, while also recognizing their humanity. I do not shed any tears for them, but rather who they could've become. I hope for the day when the Left can reform reactionaries and the like. Until then, it's a struggle for power.

You're a namefag, of course you feel that way. Drop that junk.

That's set theory, with a couple of complex numbers. I'm assuming you know what those are. If not, look it up.
I'm not great with (nor generally interested in) mathematics, but if I'm reading it right (Q = the set of rational numbers, which is normal for the blackboard-bold symbol Q, https://en.wikipedia.org/wiki/Rational_number , and the final question being what is the intersection between the set S and Q) then it's just asking which of the 6 elements of the set S are rational.
So for example, 1/3 and 22/7 are obviously rational, [pi]/3 is obviously not, and so you need to figure out if the other 3 are rational. I forget all my trig and odd/even powers of those complex fractions so someone else needs to sub in.

 No.11650

Try transforming the complex numbers into trigonometric form, they look like they will have a modulus of 1 which will make the exponentiation easy.

https://en.wikipedia.org/wiki/Polar_coordinate_system#Complex_numbers

You are asked to count the rational numbers in S. Two of them are evidently rational. π/3 is irrational, but in most contexts this will be accepted as known since the proof is non-trivial. If you can't remember the sine of π/3 take a right-angled triangle with an angle of 60 degrees and take the ratio of the opposite leg and the hypotenuse. Complete your right-angled triangle by reflection to an equilateral triangle and you will easily find the ratio to be sqrt(3)/2. For the irrationality of sqrt(3) take a^2==3*b^2 with a and b coprime, take the unique prime factorization of both sides and simply count the parity of the number of times 3 appears on each side.

For the first two values, identify them as roots of unity, a cube root and an eighth root. Recall that when raising roots of unity to natural powers you may discard multiples of the root order. Reduce 2019 modulo 3 and 8. This resolves the first value, while for the second you are left with the cube of an eighth root. Since you only need the rationality of the imaginary part you can avoid doing any computation by recalling that exponentiation by natural powers on the unit circle amounts to rotation by multiples of the base angle. Since the base angle is π/4, first quadrant, cubing takes you to 3π/4, second quadrant. This has the effect of flipping the real part sign and leaving everything else untouched, whichPost too long.

usually it is the kind of personal god that is discussed when talking about things like the problem of evil etc

https://en.wikipedia.org/wiki/Personal_god

>A personal god, or personal goddess, is a deity who can be related to as a person,[1] instead of as an impersonal force, such as the Absolute, "the All", or the "Ground of Being".

>In the scriptures of the Abrahamic religions, God is described as being a personal creator, speaking in the first person and showing emotion such as anger and pride, and sometimes appearing in anthropomorphic shape.[2] In the Pentateuch, for example, God talks with and instructs his prophets and is conceived as possessing volition, emotions (such as anger, grief and happiness), intention, and other attributes characteristic of a human person. Personal relationships with God may be described in the same ways as human relationships, such as a Father, as in Christianity, or a Friend as in Sufism.[3]

>A 2019 survey by the Pew Research Center reported that, of U.S. adults, 70% view that "God is a person with whom people can have a relationship," while 15% believe that "God is an impersonal force."[4]

This guy Is called nigel askey, and is apparently a legitimate historian. He published a paper debunking TIK's claim that the K/D ratio of the soviets during WW was 1/1.6, instead claiming that the soviets lost over 4 more times as many combatants as the Germansduring WW2. Here is his paper. I'm not a qualified historian and I dont have access to acrhives or time to research, so I can't debunk him.

http://www.operationbarbarossa.net/wp-content/uploads/2017/10/Essay-alt-view-TIK-presentation.pdf

I checked out his website and alsthough he does seem to be knowledgeable, he makes certain ridiculous claims that the "Vicors write history" in WW2, and the allies covered up how technologically and tactically inferior they were to the germans.

Hello guys, im in the search for some podcasts or discussions to listen to on headphones about communism, though please not from cringe faggot SJW's. I am not sure how you all are, my first time on leftypol.

https://www.theguardian.com/politics/2022/mar/06/fascist-fitness-how-the-far-right-is-recruiting-with-online-gym-groups

The article talks about how far-right groups use self-improvement to recruit people into their own ranks by associating positive change with Fascism.

As a former Fascist, this is basically how I got into the ideology and stayed because I had experienced genuine positive change in my life and I thought that this was somehow the miracle of Fascism.

Which made me wonder, what are left wingers opinion on fitness in general? What are their ways of combating the above issue I just mentioned?
