25 min But how does bitcoin actually work?3Blue1Brown

Sorry, 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.

22 min Group theory, abstraction, and the 196,883-dimensional monster3Blue1Brown

It 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

31 min But what is the Central Limit Theorem?3Blue1Brown

I'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.

…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

32 min Visualizing the 4d numbers Quaternions3Blue1Brown

I 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?

"So the more the wealth of a nation comes from the productive citizens of the nation, the more the power gets spread out and the more the ruler must maintain the quality of life for those citizens. The less, the less."
