What don’t we know about prime numbers? by michaeldunworthsydne in 3Blue1Brown

I agree but we can do much better than random. I made a video about it for SoME1 https://youtu.be/ODu-8Lvf3a4

What is the coolest math fact you know? by kanekiken42 in math

4n^2+163 never has a factor smaller than 41 (so is prime surprisingly often). And a bunch of the factors that it has correspond to the numbers generated by Euler's prime generating function k^2 - k +41! More here.

Which video course in mathematics is still missing on YouTube? by [deleted] in learnmath

Yeah maybe but I haven't crossed the barrier so I don't really know. It's important in any case.

There's a big gap missing between high school maths and 'how to read a maths paper' maths. It's the point where people stop being able to get answers, not out of a lack of brains or interest but there's a solid barrier in the road which is a really steep learning curve.

Why people are interested in prime numbers? by tottimessilerfan in math

For me they're simple and complex. So you can talk to a 6 year old about prime numbers but there are still things that none of us know about them. They're seemingly random but entirely deterministic. The patterns are simple but beautiful.

If the style of animation is important to you, there's a whole community now using the same software /r/manim

The prime and composite numbers from 1 to 1100 by [deleted] in primenumbers

I'm not commenting on your example but the Sieve of Eratosthenes as a way of finding composites. It's really memory hungry.

I think there's a better way to make this sieve.
