Yes.

I detested differential equations. However, that was more due to how it was presented than the underlying, surprisingly, beautiful math.

The only problem with courses like calc 3 and differential equations (in my experience, as a mathematician) is that they are cheating somewhat. By cheating I mean relying on inadequate, flawed or entirely omitted proofs. How can the students truly understand something if they are not presented the whole story (or at least reference)?

The good thing about these courses are that there are usually no shortage of relevant exercises!

Generally speaking, Library Genesis, Anna’s Archive and Sci-Hub are your friends :) Otherwise you can try to email the authors. They will probably provide you with a copy.

I can do one without doing the other. I am an atheist and do not care for religion at all. However, that does not mean I blame Jews for something another group, the Zionists, think and do. Sure there is an overlap and corrolation, but the same is also very much true for the US Christian nut jobs along with others.

If you are going to label people and reject them on the basis of their label, make sure to label them right.

Let us not confuse Zionisim with the Jewish religion, please.

When I learned about it first time I thought it sounded too good to be true. Turns out, it is just that good.

It is a joke, there are no ads. I just wrote a fake command in the Nix syntax.

LPT: In NixOS you can fix this by adding

environment.systemAds.enable = false;

to your configuration.nix file 😎

It is a work of art!

It is a triangle. The abstraction of lines in non-Euclidean geometry are geodesics and just like three lines form a triangle, so do the geodesics. If you walked along the earth’s surface from the equator to the North Pole and back, taking 90 degrees angles every time, you will have felt that you made a triangle by walking straight in three directions.

The reason the angle sum can be more than 180 degrees is that the sphere has a positive curvature. If you want one with negative curvature and less than 180 degrees angle sum, try to make one on the side of the hole on a torus (look up its curvature if my explanation was lacking).

EDIT: Picture for reference:

The answer is obvious. Depending on the curvature of the object the triangles have higher or lower than 180 degrees angle sums. Flat space just happens to have 0 curvature.

Did not know about this site. It was a nice read and their mission statement is cool. Thanks for sharing! :)

It is nice where possible and can help locally, but on scale it will not force through any changes. To see why, we only need to consider the historical material conditions that allowed the development of the current capitalist form in the first place. Small businesses where defeated by capitalists that could employ tactics the others couldn’t answer.

In order to answer to the consequences of our current mode of production, we have to force changes to how production is carried out. Saying we want our products locally, ethically and environmentally made will only change their branding, not the fundamental exploitation in search of surplus value.

When you have to spend on things like haircuts, repairs, etc, keep the money in your social network.

While I agree with the idea of not buying garbage, there is absolutely no way we can unconsume ourselves out of the capitalist ploy to extract surplus value. Do not put the blame on people who try to (often) satisfy legitimate needs, but on those forcing labor to be spent at the cost of both the environment and workers themselves.

Ecofascism (not accusing you here) is not going to solve the climate crisis.

I like people who think critically themselves (and are sometimes weird in lovely ways). Often I find them to be leftists and/or Linux users. I encourage your independent thought as to why.

Yeah, hearing about how hard it would be to get tenure dissuaded me from pursuing my original dream of doing a PhD. In retrospect I think I am much happier where I am now than I would’ve been, which really is what matter the most to me now. Freeing myself of the obligation of attaining my goals was actually quite nice.

I misinterpreted your comment and was very pleasantly surprised that something named “rational wiki” would call him out for the crackpot that he is.

Yeah, this is not a nazi bar.

I am pretty certain our brains evolved to filter out friendly/known voices some tens of thousands of years (or more) ago. I feel tired sometimes before and after coffee, and often less so on coffee breaks because the real issue with coffee is that the caffeine can definitely disrupt sleep.

I understand you need consistency to not be engaged by sounds. I hope you understand that other people have other limitations, hence, again, it is your first statement I disagree with.
