Me first: Alexander horned sphere

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

Basically it is a 3D fractal that is by itself not all that special, but it breaks its surrounding area so bad that the concept of volume becomes meaningless. Imagine that, a 3D object that is so weird it transforms the space it occupies into something else. I thought this is pretty cool

I don't believe in such a thing. Everything can be trained. Sure, some people may be born with an inherent aptitude towards something but you can close that gap with hard work.

school math is easy, but i want to go to economics, and some people say that only mathematical analysis is used there. is it true?

Technically I have dyscalcula because any set of numbers arranged together greater than 4 (literally just anything above 10,000) starts to get hard to read
But that doesn't mean I can't do maths
Dyscalcula is a psyop op made by big paper companies to sell coloured paper

What 'economics' are you planning on doing?
Statistical mathematics is a whole university subject entirely, if you want to be a quant (quantative trader) then start there.
Quants essentially make predictions on the most snca events and how these influence asset prices (such as the temperature in texas on a certain day, which will affect oil flow which will influence oil prices)
A quant position is the most math intensive side of trading, you'll get a job at a prop firm and you'll be making calculations most of the time. If you like solving math problems and you love money, then being a quant is a dream job kek
There's shit like the black scholes model but that's literally just a plug n play options formula. There's really not that much to it.
you also don't need to be a quant to make fundamental analysis. You don't have to learn maths to get into economics, being a quant is a lot of work.
The returns are great but not necessary for profit.

Last one for today: https://en.wikipedia.org/wiki/List_of_baryons

Protons and neutrons are baryons. They are basically a combination of 3 quarks. The interesting thing here to note is how out of all the possible baryons, only protons are stable. Even crazier is how neutrons by themselves decay after a couple of minutes, but become permanently stable when inside a nucleus. This is because the rest mass/energy of the neutron is extremely close to the rest mass of the protons. The neutron "disperses" some of its energy while forming a nucleus, allowing it to shed the extra energy and thus become stable. If this difference in rest mass were to be different by even 10% or 1% I forget which, then chemistry would not be possible and everything would decay very quickly. One of the many signs of fine tuning.

I found a new way to make a heart-shaped graph. I haven't seen anyone do it with a parametric function like I have before.

This represents the function abs(x)^abs(x) after being transformed by a circle inversion. (specifically, this is a circle inversion with a center at the origin and a radius of inversion of 1)
I think this looks the most heart-shaped out of the other ways of making one. I don't like the implicit curve one (i.e. (x^2 + y^2 -1)^3 = x^2 * y^3) as it looks a little bit squashed, and cardioids don't really look like hearts to begin with, despite their name. If you know any better ones, please post
