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.
Mentioned as a favorite 3Blue1Brown video and a related watch in threads about deep mathematical structure.
“you should probably see this Matt Parker video about excel being used in ways it shouldn't maybe?”

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?
