Anyone else low IQ high interest here? Post feels.
So R is the set with the elements x that are not in x. But x = x, so the elements x that are not in x is nothing, which would mean R is the empty set. What's wrong with this reasoning?
What the hell is "real analysis" and "calculus"? In my country, we have "mathematical analysis I-III" courses, where we deal with differential and integral calculus (single and multivariable), metric spaces, infinite series and basics of vector analysis and ODE (not in this order). From the beginning everything is done in a rigorous manner with proofs. My assumption is that "calculus" is just analysis without proofs and "real analysis" = enter epsilon-delta. Am I Correct ?
Ayyyyy lmao Real Analysis is stuff with sequences, limits, compactness, limsup/liminf, series and all that jazz. Sorry I'm drunk I can't really explain it that well, but basically real analysis is harder than your usual stuff breh.
/sci/ you tell me that STEM is a meme and you can't get jobs.
So tell me this, /sci/, why aren't any of you becoming actuaries?
I'm trying to work through this exam problem, anyone know how to show that this mixture exists at vapor-liquid equilibrium? I assume I need to find a way t show that the fugacity of the vapor and liquid phases can be equal to each other at the given conditions but I'm not really sure how to start with all the information just thrown at me.
Anyone know if I did these right/ know how to do this one?

>They're just proving that the plasma could be stable.
What's significant about that? The Brits did it year's ago, the problem you only get something like 0.65 the energy out that you put in.
How do i master Wolfram Mathematica in 3 days.
Note my programing skills are low tier.
anyone know where I could 'Classics in Total Synthesis III' from KC Nicolaou from? libgen has nothing
Do you guys have a large collection of textbooks like Gentoomen's Library?
I assume this belongs on /sci/...
Anyone here into growing your own crystals? I'm bored shitless and I want some to grow, any ideas? Prefereably some realitively simple ones, but NO copper sulfate ones, I fucking mean it.
When can I call myself a mathematician?
I'm almost done with my bachelors in math
When I hear the term, it means to me that you are working in the field or actively doing research. It's a description of what you do. Call yourself an artist if you do art. Call yourself a computer programmer if you program computers. Call yourself a mathematician if you do math.
Being a math student doesn't qualify in itself. There's a term for that.
I don't think you need to have a PhD or be a professor or anything like that. There are amateur mathematicians who make significant contributions.
Anyone have any experience with putting a matrix through a linear equation? Drowning computer science major here. Googling extensively isn't getting me anywhere. Any help would be greatly appreciated! (:
If the point of that exercise is finding nth powers of square matrices easily you should look up eigenvalues/vectors and diagonalization of matrices. Otherwise you can just do it the slow way, which in this case may be faster.
Im curious as to how good the math niggas on /sci/ are when they are handed an actual problem, since proofs these days can be regurgitated by anyone. Ill start off with pic related. If we substitute every circle with spheres, what is the total Volume of all the spheres? If you need an explanation behind the pattern of the circles, Its a dead ringer that you are not capable of solving said problem.
Name a better calculator.
Protip: You can't.
Can it play DOOM?
>Not ripping and tearing during lectures
Hi /sci/, so i have a project due tomarrow, i need to make a bridge out of toothpicks. It has to span 40 cm with room for a block of 14x9 cm to put weights on. All i can use is this glue and toothpicks. This is what I have so far. Any ideas anons?
see the problem with the toothpick bridge project is the glue needs time to dry. no matter how good your design is, the bridge will fail because of the not quite dry glue.
this means you do not have time to make an elegant design, like the girl who will win this year with a beautiful thin sloping style. you will have to make a design similar to this piece of shit this girl is holding, just a garbage amalgam of toothpicks and glue which will be destroyed immediately
Are you going for a design like this?
This is not a homework question, I just think I just fucked up my final.
How would I solve this for sigma?
I really thought the only way would be to use logarithms.
