SoME1 is an exposition held by 3b1b and friends, in which mathematical presentations of all forms (PDFs, animations, jupyter notebooks, to name a few) were summoned and reviewed in the summer of 2021.
The top 5 submissions selected by the jury was made into a short video introduction on 3b1b's YouTube channel.
I also participated by submitting a Pluto notebook, introducing the topic of norms on linear transformations. Unfortunately, I did not get selected even into the top 100. However, if you are interested in knowing my opinion on the subject, you are welcome to click into the link above.
