do you think an omnipotent god would be able to carry out Banach Tarski as an experiment

Mathematics is just a depressing subject. All you learn is how much there is that you do not know and how much one can forget.

@EE18 this is called squeeze theorem, usually. Comparison theorem says among others that if $a_n, b_n$ are sequences of non-negative numbers, $a_n\leq b_n$, then $\sum_n b_n < \infty$ implies $\sum a_n < \infty$

Hmm... every open cover has an open refinement of size $\leq \kappa$ iff every open cover has a subcover of size $\leq \kappa$

maybe the foundation of mathematics is not about legitimacy, or about truth, maybe it was all along about the friends we made along the way

Maybe, as a general note to everyone in this room: people get annoyed when they see the same kind of content over and over again from the same person (whether it be requests for feedback on their posts, requests for input in other chatrooms, or advertisements for their own personal projects or websites). Please try to limit these kinds of comments.

Instead of complaining and whining incessantly, you should appreciate the help you do get. It's remarkable that there is a place like this where professionals provide their services literally for free and out of the goodness of their own hearts.

and if you aren't willing to take the time to investigate something like that, why should anyone else? i mean no offense, but this issue comes up a lot on MSE where people focus way too much on the exact form or phrasing of the feedback they are given, and less on what they would do if they were stuck on a desert island with only that feedback, and forced to think about where it would lead them.

Yeah, I agree, but the thought: "You're not good enough no matter how much you study; maybe you should do something you enjoy less but you're better at" is always in the back of my mind. It's really draining sometimes...

@Shaun expect update on that ArrowGlue project later on. Just been busy with work stuff, and also have to reconsider things using PEG grammars instead of EBNF, for grammar ambiguity reasons.

Reuse of human excreta

Reuse of human excreta is the safe, beneficial use of treated human excreta after applying suitable treatment steps and risk management approaches that are customized for the intended reuse application. Beneficial uses of the treated excreta may focus on using the plant-available nutrients (mainly nitrogen, phosphorus and potassium) that are contained in the treated excreta. They may also make use of the organic matter and energy contained in the excreta. To a lesser extent, reuse of the excreta's water content might also take place, although this is better known as water reclamation from municipal...

ted's so old that when he uses chalk to lecture, he sometimes recognizes the plankton minerals in it from when the plankton were alive. this leads to some poignant moments at the beginning of his multivariable calc videos.
