Can't believe 3b1b animated a person using his python library!!

He's a paid actor lip syncing 3B1B voice AI.

Hearing him say “you must’ve worked hard on that” almost made me cry it felt so good to hear. I’ve loved math from the day I learned to count at age 2 and I’ve ran with it ever since. I’m 18 now and studying math and physics at the university level. Yet despite participating in competitions and in classes to help better my understanding and the understanding of my classmates, I’ve never once heard someone say to me “you must’ve worked hard on that”. I’ve heard you’re smart or a similar statement about my math, but I’ve never heard that. I think about math all the time. I consider parts of the subject all day everyday. I love it, but that doesn’t mean wrapping your head around these concepts is easy. But with math, nobody ever says “you must’ve worked hard at that”. They just think you were born with it and move on. I wasn’t born with it. I spent most waking moments of my life thinking about it and so I ended up being pretty good at it.

Wasn’t a “math person” untill i found this channel, thank you.

[vidblogger]

Whoa. Your animation is getting so much better. It looks so realistic!

[girimsp]

I wasn’t born during the times of Euler, Guass, Einstein or Tesla. but I was very much alive in the 3blue1brown era.
Man, hats off to your work!!

[SP-qiur]

I always imagined him as a balding badass in his late 40s. Still it's a pleasant surprise

[zerodivider]

Its always funny when you get to physically see someone you have only listened to. They never match. Lol. Love your work!

[quahntasy]

Yeah Love this Q& A video.Please do more like this.

And wasn't it lovely to see the man behind that mathy voice?

[m_riatik]

facts:
1. grant is hot
2. grant deserves every bit of success he gets
3. grant is quite arguably the best math educator on youtube
4. grant is hot

I don't comment in YouTube in general, but with the hope that the creators read them, I'd like to say thank you.
I graduated in physics last semester, but it wasn't until your video on curls that I truly appreciated EM field theory. Well...of course I appreciated maxwells equations, but seeing and hearing your python library bring a simple visualisation to it is so awe inspiring that it brought a grander appreciation! Thank you, sirs. Like many others, you are bringing the vision of a greater understanding and availability to learning physics (math) that Feynman would have loved to see.

There are some people no one can hate. Grant is one of them ☀️

[DANversusWTP]

0:25 He makes the same exact arm gestures that one of his pi's would.

[drone_better]

Wait. What? You... You have a face? I always thought you were the disembodied voice of a god with a math-animating python library, who really liked maths, but... I guess, this makes more sense.

[feynstein]

Lol what sorcery is this? My brain refuses to accept that the input from my eyes and from my ears are from the same person.

I have been a follower of your channel for a few years now and I wanted to thank you for your amazing content. I began my academic life as a philosophy student and slowly found my way into physics as the questions I became most obsessed with dealt with the essential nature and fundemental structure of reality. As I began exploring more contemporary fields of physics, i began marveling at the elegance of the pure mathematics underpinning the theory. It was around that time that i also discovered your channel and fell in love with a third field of study. You helped inspired me to pick up a second degree in pure maths and i credit much of my passion and success to your videos and commentary.

It can be so difficult to look at a black and white textbook and distill out the visual and conceptual intuitions beneath the algebraic and numerical abstraction. I suppose part of the fun of pure maths are those moments of profound insight, when all of the gears mesh together and those insight come forth organically, but it is also quite amazing to see those intuitions and images take such beautiful form on screen. Of the topics I have studied thus far, I have found your animations and explainations to be not only accurate and beautiful, but also essential. You bring life to the essence of mathematics in a way that makes the abstract feel almost concrete.

Keep up the good work! I'm so happy to see you find a career that helps others through the marriage of two of your favorite subjects. 1.1M+ followers are lucky your love for mathematics beat out your want of a career.

He looks like a Harvard student from the 1940s.

[ajlakanen]

I wish that for a one single day in my life I could speak as clearly as him, and express my thoughts in such a lucid and direct style.

[tibees]

I didn't know Jabrils worked on your videos, he's cool!

[shaylempert]

I don't think that there is a better time to thank you for what you do.
I was struggling with math ever since I got back from the US(the math level at the state I lived in, wasn't great). But your videos have played a big role in me falling in love with math. Now, at the age of 17, I have finished school and am ready to start university, with knowledge and intuition of linear algebra, calculus 1, and multi-variable calculus. And this is thanks to you.
