Fantastic channel, and I love that he named it (and designed the logo) after his heterochromia: https://en.wikipedia.org/wiki/Heterochromia_iridum

From his FAQ:

What does the name 3blue1brown refer to?

I'll be the first to admit this is a little odd. The logo is a loose depiction of my right eye color. It has what's known as "sectoral heterochromia", meaning there are different colors in different sectors, which in my case looks like 3/4 blue and 1/4 brown.

In the same way that many channels simply share their name with the author, a younger me thought that a more genetic signature might be neat. Plus, the channel is all about seeing math in certain ways, so it felt fitting. The name is just a reference to the logo, factoring in a desire for something deliberately weird-sounding that stands out.

Grant makes some amazing content. His visualization of the Fourier Transform[1] actually enabled me to understand the how it was happening behind the what was happening with one of the most used algorithms in computing. [1] https://m.youtube.com/watch?v=spUNpyF58BY

In terms of simple word-explanations, I've always thought of it as taking a flat strip of LED lights (imagine the eyes of Battlestar Galactica Cylon robots), then sticking a nail through the center and then spinning it around.

Depending on how fast you spin it, the resulting blob-o-light will have different shapes. If it's a simple oscillation and you spin it at exactly the right rate(s), you'll get a straight line again, whereas pure chaos will always make round blobs.

Seriously, his explanations on topics go well beyond the lectures some of my professors provide and could probably benefit a lot of students if given as a resource... If only academia wasn't so distrustful of those outside their circles...

My son is doing A-level maths and has found these videos helpful for getting a different perspective and a deeper understanding.

But he's not even outside their circles right? Doesn't 3b1b have a PhD? I can tell you at least that we watched some 3b1b videos in my university undergrad math classes last year!

As someone much more effective at learning though text than by watching videos, I really appreciate the creators who do the additional effort of publishing a written version.

For anyone interested in the code used in his animations, the repo is here: https://github.com/3b1b/videos It's pretty impressive. A lot of work goes into these videos. My other favourite YouTube math guy is eigenchris. His tensor calculus series is legendary: https://www.youtube.com/playlist?list=PLJHszsWbB6hpk5h8lSfBk... In complete contrast to 3b1b, eigenchris creates his videos entirely in PowerPoint, which makes…

Another great YouTube math guy is Eddie Woo. They’re recordings of him teaching high school math, and he does such a great job at engaging his class (and viewers).

To add a different recommendation on math, Michael Penn's math channels on youtube are great. It helping me study some more advanced topics.

And that's a good place to stop :)

That's so encouraging to hear, I would've loved uni maths with some high quality videos like his to watch, even if just for after class to reinforce the topics.
