But how does bitcoin actually work?3Blue1BrownSorry, on mobile so not very detailed, but the YouTube user 3Blue1Brown, who has ~275k followed and posts fantastic videos about math, just posted a video describing how Bitcoin works. We should lobby him to do an Ethereum video! Here is his channel page. Idk how best to lobby him.

Why slicing a cone gives an ellipse (beautiful proof)3Blue1BrownEdit: I just found that he had already made a video on a similar topic!!! That question had troubled me ever since I started learning co-ordinate geometry. Watching that video literally made me cry;_;

Group theory, abstraction, and the 196,883-dimensional monster3Blue1BrownIt involves the study of algebraic structures. I imagine you are likely familiar with groups (in the case you aren't, here is a good introduction), and perhaps with rings and fields as well. This subject can get very abstract. As for textbooks, I like Dummit and Foote for its comprehensiveness but it's quite dry. Haven't read any of it

But what is the Central Limit Theorem?3Blue1BrownI've watched the Central Limit Theorem video. And so I suggested by getting item 2, or not getting neither of the items, many times, your actual chances of getting item 1 increases over time, since the probability of a random set over multiple cycles is supposed to form a bell curve shape, and so getting only one of the outcomes multiple times would yield for there to be sets of data for the other outcomes too.

But what are Hamming codes? The origin of error correction3Blue1BrownThere's already a 3blue1brown video on classical Hamming codes, and quantum analogues of some of these features are quite doable. It's also quite surprising that such correction even works. I'm a research physicist and would be happy to help!

Exploring How Computers WorkSebastian Lague…about how that all works, but basically it's a two step process: 1) invert the signals, 2) add binary 1 to that result. Sebstian's video discusses it here: The OR going into them is just something temporary I put there to send a "1" binary signal into the XORs which is to toggle on 'subtraction' mode. When that 1 goes into the XORs then they

Visualizing the 4d numbers Quaternions3Blue1BrownI have recently stumbled upon the concept of hyperbolic space, and was wondering if you could create videos related to this topic. I only know the basics, yet from your quaternion video(part1, around the 16 minute mark) I recognized an interesting fact on how the projection of a 3d sphere onto a 2d plane seemed to produce hyperbolic geometry. Could you create something more in depth relating to this phenomenon?
