The nice thing that happened in class today:
Grade 5 students solve a puzzle where they put cuneiform numbers in order (there is no guidance, just work with the symbols, how do you order them?)
I told them they are like archeologists cracking a code. They did it!
"But where is zero?"
"It wasn't invented yet." I said this seriously. I mean ... it's true.Later that day the same student asked if it was a joke. I got to tell them no! Zero had to be invented. Everything had to be invented!
@futurebird the additive identity
-
This student wants to "invent a new zero" so. Watch out everyone. Math is about to get a lot more... IDK ... but MORE.
@futurebird More... Zero? They do know what zero plus more zero is, right? 🤭
-
@futurebird for a while there, no joke, computing was flirting with upper and lowercase zeroes…
@mhoye @futurebird IEE754 has positive and negative zero.

@futurebird new Zero-Plus(tm), for all your complicated computational needs!

@futurebird
[sighs in iEEE 754 signed zero] -
@futurebird admittedly I'm not the best at math and I do have an anthropology degree (MesoAmerica was one of the places that independently invented Zero but I'm sure you already knew that)
But I can't FATHOM counting or math without zero.
There must be a way to make sense of it, but I haven't come to that answer
@lapis @futurebird If you’re counting physical things, then I believe you don’t need a zero. -

@futurebird …or perhaps less

@futurebird we have so many zeroes tho

@futurebird this story has saved my day from being bleh.

@futurebird
I've been in the late-capitalist dystopia long enough that "new zero" sounds like "now you need an app and a subscription to do math". -

last time this happened we got Javascript and the infamous "WAT" talk lol

@kbm0 @futurebird the kid is on to a fundamental truth of math, that you can always ask questions with the tools you have that seem to make no sense until we decide, what would have to go in that slot so they did make sense? So we get zero, then negative numbers, then fractions, soon irrationals, and and and and

Hee-hee, topologist have already got "the line with two origins", but we gotta let this student run free and see what they come up with on their own.

@mhoye @futurebird Typography has uppercase and lowercase zeroes, but they are usually called lining and old style figures

@lapis @futurebird The concept of "nothing" was known. What people didn't have was place-value number representation.
So there was no easy way to multiply by, say, 10 (assuming your base was 10).
Compare arithmetic with roman numerals versus arithmetic with indo-arabic numerals.

@futurebird And of all the numbers, zero had to be invented the most!

Maybe ϵ would be another "zero at home"
