Great Maths Channels

[kram1032]

Here are two great YouTube channels covering mathsy topics in ways you might not have seen them before:

3Blue1Brown (YouTube)
Example video:

This channel also has a blog associated with it. 3Blue1Brown (Blog) - Grant Sanderson currently also works at Khan Academy. He said he is busy for now so it'll take him some time to get more videos up in the nearish future he already has a bunch of topics which he wants to cover. The example video sneakily motivates p-adic numbers and shows a geometric way to represent the special case that is 2-adic. This geometric representation is secretly related to fractals. For instance, if you go for representing 3-adic numbers, much in the same way he did 2-adic ones in this video, the way to properly draw them is a Sierpinski triangle and you might see something resembling a cantor-set in the 2-adic ones.

Burkard Polster is obsessed with Rubik's Cubes, Klein-bottles and perhaps surprising pieces of math found on TV, in games or in memes. But, as shown in the example video, he also covers other really interesting stuff besides this.
He is professional mathematician (specializing in Geometry) at Monash University
He is also behind QEDcat and for his Channel he works together with Giuseppe Geracitano (LinkedIn)

Have fun with those

Those are nice.
