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".

"John William Shirley (1908–1988) published reproductions of two of Harriot’s undated manuscript pages, which, he claimed, showed that Harriot had invented binary numeration “nearly a century before Leibniz’s time”"

@elysdir Thinking about it, the numerals remind me very much of the numerals
en.wikipedia.org/wiki/Maya_num 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.

@elysdir

Addition, subtraction and division are surprisingly visual with Kaktovik numerals.
