People who memorise digits of π

Never has "Rambleman" been so accurate

(actually it was prob more for @Hawks but whatever)

BLUE

DOES HE EVER RANDOMLY YELL BLUE?

THEN IM BETTTTTEEEERRRRRRR

...

No, he has not

You win.

[NerdSandwich she/her]

Does he yell MIMI?
That's what MY SISTER DOES.

MMIIIMMIII!!!!!!

I've only memorized 17 digits (3.14159265358979323), although I had a friend who knew up to like 210 (he was also doing precalc in 7th grade)

[NerdSandwich she/her]

yo I'm only in that as a freshman wut

Welcome!

210 is very impressive. Did he use the song or something else?

And that's still more than I know without the song, so...

Sigh.

Do you know what digits 99 and 100 of π are?

[First of the Tide He/him]

Nope! I only have pi up to 3.14159265358979323846264

e up to 2.182818284590

sqrt 3 up to 1.732050807

sqrt 5 up to 2.236067977

and all other prime sqrts until 23 up to 5 digits past the decimal

I realize now that I am very very oblivious and just wanted to brag

*air juggles*

wait, you COUNT THE ONES DIGIT? eww

Yeah what's wrong with the one's digit

It's a digit

So

Why is sqrt(2) better?

[First of the Tide He/him]

some context: I compete in math team competitions.

when solving an eq. w/ pi, you almost always have to put it in terms of pi or use 3.14 or 22/7 for pi. knowing more digits than that will likely never help. but sqrt problems need a variety of answer types. knowing plenty of digits can help you brute force problems even if you don't know the trick. specifically, I had to solve (sqrt2)^sqrt2 to 3 decimals, and I  had no idea abt the log rules to do it. but brute force...
This might be a bad example, I spent literally half of the time on a fifty-question test on this one question trying to brute force it, but I still got it right, and got 6th individual at the comp overall

So what you're saying is memorising sqrt(2) is more useful

But this thread is not for things that are useful

No one ever actually uses more than 30 digits of π

It's why I memorise it

Of course, there's also people who do it for π memorising contests, but those contests exist partly for this reason

[First of the Tide He/him]

yes, but sqrt2 is similarly impressive and useful

But usefulness makes it less impressive

You memorise sqrt(2) for brute-forcing stuff

I memorise π for the sake of memorising it

honestly yes the sqrt of 2 is def more useful but pi......PIE

aw shoot I'm hungry now

[Through The Living Ash he/him]

No, I find myself using pi way more than I ever use root 2. Root 2 usually only shows up for actual square root things and some trig things, but pi is there for everything with a curve.

[NerdSandwich she/her]

true but you don't need to know very many digits

[Through The Living Ash he/him]

Also true. I didn't memorize them on purpose; my sisters are obsessed with the song and so it kinda happened on accident from just getting it stuck in my head too much.
