A video by Veritasium that gives a relatively low level introduction to the p-adic number system. It was 'low' enough that I understood most of it. 🙂 It also gives me a better appreciation of the @gregeganSF story, "3-adica".

@elysdir Thinking about it, the #Kaktovik numerals remind me very much of the #Maya numerals
https://en.wikipedia.org/wiki/Maya_numerals which also use a combination of base 5 and base 20. Not surprisingly the two may be culturally related, given the flow of people and information across the American continent.
