3Blue1Brown (Grant Sanderson) · Library
3Blue1Brown is a mathematical-visualisation YouTube channel created by Grant Sanderson (Stanford University mathematics graduate, formerly of Khan Academy), focused on producing visually-rich animated explanations of mathematical concepts using the Manim animation library that Sanderson developed and open-sourced. Founded in 2015, the channel has grown through 2015-2024 to ~7+ million subscribers as of 2024 with substantial cross-disciplinary mathematical-research-community engagement plus broader STEM-education-and-popular-science audience reach.\n\nThe editorial approach combines substantial animation-and-visualisation craft with substantial mathematical-rigor and accessible pedagogy. Major series have covered Essence of Calculus (the foundational 11-episode calculus series), Essence of Linear Algebra (the substantial 16-episode linear-algebra series, widely used by university-and-self-study learners), Neural Networks (the substantial 4-episode introduction to deep-learning), Differential Equations, Probability of Distributions, plus the substantial annual Summer of Math Exposition (SoME) competition that Sanderson sponsors to encourage broader mathematical-explanation-creator community development. The Manim animation library has substantial post-2018 community-fork (the substantial ManimCommunity edition with active development) plus broader adoption across mathematical-education content-creator community.\n\nFor a globally-mobile professional with mathematical-and-engineering interests, 3Blue1Brown provides substantive free mathematical-visualisation content. Indian-learner engagement is substantial particularly among Indian engineering-and-science students plus the substantial post-2020 Indian competitive-examination-and-IIT-JEE preparation community. The Essence of Linear Algebra series in particular has been widely-adopted as supplementary content for engineering-and-CS coursework globally.
