I signed in for the purpose of leaving this comment. This dude is amazing, and the only thing I regret more is not being able to find this channel sooner. He’s unbelievable, I really hopes he hits his goals

Very fascinating that a child would come across this problems, just like any child, if you give a very hard, tedious questions, they will try to find a shortcut so that they can quickly finish off their work or homework and play outside.

Nothing do I love more than when a concept is introduced with context and origins.

An elementary school kid came up with this? I bet his teacher was dumbfounded lmao

I am so grateful to have the Gauss thing explained so very clearly to me! I didn't understand the explanation in my text book. Now I can visualise it wonderfully clearly and see the structure of the idea very well. Thank you.
