Grant Sanderson (the guy behind 3Blue1Brown on YouTube), and by extension Manim, has done so much for increasing the accessibility of math and computer science.
Like, it’s hard to over-state how enriching it is to have engaging animated visuals if you’re just the average schmuck trying to make it through an engineering undergrad at university.
Seriously: Thanks to Grant, I was able to pick up my Quantum Mechanics textbook again and actually know what the fuck was going on.
