Math and art — two seemingly vastly different subjects. But despite the apparent opposition between the two, YouTuber Grant Sanderson has set out on an endeavor to combine them in his channel, 3blue1brown, named after the sectoral heterochromia that leaves his right eye ¾ blue and ¼ brown. His videos essentially animate math, providing visual depictions of the topics he covers using a Python library of his creation.

Grant studied math at Stanford University and later went on to produce content about multivariable calculus for Khan Academy. Eventually, his love for mathematics (and passion for teaching it to others) led him to create 3blue1brown, which has now amassed over 800,000 subscribers.

His videos vary in focus. Many discuss topics that are typically not covered in traditional math classes, such as topology, Bitcoin, higher dimensions, and more conceptual subjects (an example being a video entitled “What does it feel like to invent math?”). But he also has series that are oriented to students learning particular math topics, such as calculus and linear algebra.

Grant’s goal is to “bring life to math,” animating it in both a literal and figurative sense. Math can be difficult and hard to fully comprehend, but displaying it with visuals and graphics allows him to break through such a learning barrier and help viewers understand math as they should. By looking at problems through a different lens and in a new format, complex solutions don’t seem so daunting and instead become enjoyable.
