So I've got a small discovery I just made, wondering if we can figure out what's going on.
I have no idea what's going on but 3b1b did a video on something similar a while ago.

Also there are a lot of these cool number visualizations. Most recently I came across this one. The math and code website is pretty cool but I couldn't find the algebraic numbers picture on it.

Thank you, that's such an awesome visualization. I found that even just plotting random 2D functions can be very beautiful, for example these are some that I've once made:
with formulas:
Code: Select all
gaussian_curve((x^2) mod (abs(sin(x + y)) + 0.001) + (y^2) mod (abs(sin(x - y)) + 0.001))
sqrt(abs(sin(x + cos(y + sin(x + cos(y)))) * sin(y + cos(x + sin(y + cos(x))))))
r = sin(1.2 * y + 2.5 * sin(x) + 2 * cos(2.25 * y) * sin(x)); log(2 * sqrt(abs(r)) - r)
(I've written a browser tool for these but it somehow lags in new browsers now, not sure why.

That tool is fucking sick dude. This is probably the coolest one I've been able to make so far.
Code: Select all
return (hash16(gauss((x) % ((y) % (f)))));
The ones you made kinda remind of of M.C. Escher tile paintings but more abstract.

3. I'm really a newbie so I only know elementary Mathematics, but I really like the very simple geometric proof of
Thales' Circle Theorem and
De Moivre's Formula/
Euler's Formula connecting the Complex Numbers and Trigonometry. The algebraic/geometric proofs relating to Trigonometry in general are some of the most accessible pieces of Mathematics, and thus enjoyable can be enjoyed by most people who have atleast some understanding of Highschool Mathematics (or earlier levels depending on your education system).
Speaking of this, I like how Euler dealt with this on his book:
cos^2 + sin^2 = 1
[cos(t) + i sin(t)] * [cos(t) - i sin(t)] = 1
[cos(t) + i sin(t)] * [cos(-t) + i sin(-t)] = 1
exp(it) * exp(-it) = 1

There are uncountably many.
But recently, I'm quite attracted to
Musical Set Theory. Because of Pythagoreanism. If you like finite groups, you would like this too.
Maybe
this post of mine could be a nice introduction.

One of the things I'm interested in getting some level of understanding in the future as I do my studies is Algebraic Geometry, since it comes up or gets mentioned so often from the maths spaces I've lurked on online.
Take a look at Richard Southwell’s Foundations of projective geometry playlist. I think you are best off learning some basics of projective geometry to get a better intuition for algebraic geometry, then eventually you can work up to Matthew Morrow’s “Algebraic K-theory and its current role in arithmetic geometry.”

Does anybody here have any books they'd recommend about the history of mathematics for relative beginners/laypersons? I've honestly never been very attracted to mathematics even though I can respect it a lot, but the history and development of it has piqued my interest before. Documentaries/videos/online texts and whatever else are welcome as well!

Maybe
Thomas Heath's works would be good for you.
If you want something modern, I guess directly reading some of Euler's works like
Elements of Algebra would be good. The book even starts with what numbers are.

Seconding Heath.
But if you are looking for something very introductory, I can tentatively recommend Snezana Lawrence, A Little History of Mathematics (Yale University Press, 2025). I would just also point you to this
blog post for an evaluation of the book and its shortcomings.
Here is a good blog post with more recommendations of a slightly more academic nature.

The formalization of abstract patterns such that new and unseen patterns not seen in physical reality could be inferred and understood.

In terms of their work, Jim Lambek, Georg Cantor, Claude Shannon and Richard Montague are the few that come to mind.

Mainly the discrete/logical side (I wish I knew more about analysis and calculus); set theory, graph theory, mathematical logic at large, formal language theory, etc. Most of my knowledge about it exists to the extent that it is pertinent to the field of linguistics, and a very good bit of it is, especially in the modern day with the distributional semantics-based embedding systems in modern AI allowing for continuous vector representations of meaning. I think linear algebra will only grow to be more important as a skill for linguists, as well as information theory (unless you consider that a branch of CS).
