Where does /sci/ stand on the pi vs tau debate?

If you actually care about this then you're on the losing side of the debate.

I choose pi because it has greater recognition, and every book already uses it.

I legitimately am on the autism spectrum.

I hate standard mathematical notation. I think it can actually inhibit learning for a statistically significant number of kids.

I NEED to use tau in my own notes. But I do not struggle with pi.

I also autistically must slash my 0s, cross my 7s, and flag my 1s.

I think it makes more sense to teach Tau to kids in highschool, since it intuitively makes more sense when talking about radians, but outside of that I don't see any reason to not just use either or situationally.

Radians are the only reason to ever actually use pi, and often that involves equations that cover a full rotation/revolution/turn. Arbitrarily having pi only cover half of a circle obfuscates how useful radians are.

It doesn't help that people can't seem to abandon sexagesimal degrees despite them being annoying to work with most of the time.

Because it's 60 * 6. Incidentally the value of tau is about 6.283. Also the French invented gradians and for some reason they're still supported to this day.

Pi is more natural, and I'll explain why

Imagine being "chad" in>>10888523
and using e^i(tau) equal 1. Try to derive the definition of i from this formula.
>protip: you can't
why? because i could equal plus/minus root(-1). From the regular formula, e^ipi equal -1, i can be derived. Sorry if none of you are good enough at math to understand the field theory and complex analysis behind this, as I won't bother explaining it. Take it from a real mathematician, (you) don't get it.

silly poster, it makes no difference to anything if you define the imaginary unit by $i = -\sqrt{-1}$ instead of $i = \sqrt{-1}$ , in fact this ambiguity is expressed by the more natural statement $i^2 = -1$ . There are no consequences of this redefinition for field theory, complex analysis or otherwise.

People who say tau makes radians easier to understand don't understand what a radian is. If you understand them and you know the formula for the circumference of a fucking circle you should see why it's 2pi.

>>e^i(pi)/2 is i still doesn't work
so let's say you want to redefine $i$ to $-i$ .
now $e^{i \pi/2} = i$ as it should be, but $e^{-i \pi/2}=-i$ , not $i$ . However we redefined $i$ to $-i$ , so in fact we should really write $e^{I \pi/2}=I$ , where $I=-i$ , which as we can see is completely symmetric with the statement $e^{i \pi/2} = i$ but with $i$ replaced by $I=-i$ . As long as we are entirely consistent with our replacement, it shouldn't make a difference to anything.

because 360 is a very dividable number. It divides into 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180 and 360, for a total of 24 divisors whereas 400 only divides into 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 for a total of 15 divisors.
