Mentioned as a favorite 3Blue1Brown video and a related watch in threads about deep mathematical structure.
3Blue1Brown introduces group theory and abstract groups, then builds toward classification of finite simple groups and the enormous Monster group with its 196,883 dimensions.
“you should probably see this Matt Parker video about excel being used in ways it shouldn't maybe?” (HN, 2023)
3b1b uses a python library for creating those videos. [link] As far as a math educator/communicator, one of my favorite videos of his is the video on the monster. [this video] Also since we're talking about powerpoint here you should probably see this Matt Parker video about excel being used in ways it shouldn't maybe? [link]
Commenter's favorite video from 3Blue1Brown, on the Monster group.
As a noob I'd say this also falls into that category: [0]. Who knows, if enough people ask about it on his reddit (topic requests) :) : [1] [0] [this video] [1] [link]
Offered as an example of a topic from the Monster group video.
