Happy Pi Day!! 🥧 (And how I sorta like Tau better)

I was waiting for Pi day ever since March started and now that its here, I totally forgot about it!

I remember that when I was little I watched a video by ViHart (who is sadly no longer on YouTube anymore, but I urge you guys to watch her videos, they're awesome. She taught me hexaflexagons, and infinities and many more things link).

Yeah so in that video, ViHart talked about how Tau is much better than Pi.

And what is even Tau, you may ask, its actually

τ = 2π

And why is it better, you may ask. Well, you know Pi has been the OG math symbol for all children and adults alike so now if someone comes along saying so 2π is better that's almost like saying no 1 is no longer the first number we would like 3 to be the first number.

But actually there are many reasons why Tau is better, for instance, we define Pi as

π = circumference / diameter

so

circumference = π × diameter

But since

diameter = 2r

we rewrite it as

circumference = 2πr

But really had just Tau been there we could easily have used circumference as

circumference = τr

which is much more easier to understand by children just beginning to learn about it!

But dont take it from me, take it from Numberphile and many other math youtubers (that's where I get all my nerd thoughts from :))

So yeah, Happy Pi Day I guess....
