If anyone is curious, I looked it up and The Guinness Book of World Records currently recognizes Rajveer Meena as the world record holder for Pi memorization. He recited 70'000 digits of Pi while blindfolded in about ten hours in 2015. I can't even begin to understand how someone could actually do that.
I memorized 100 digits some years ago using physical memory. I would type the digits of pi on the numpad and memorize the movements of my hand, how it feels and which button goes when by position. Then when I would have to recite it, I'd imagine a numpad, move my hand and just say the number that corresponds to the imaginary button I'm pressing.
Don't know if that could work for 70k digits though

This beats the approximations used in ancient Sumer (3.1065) and China (3). Try contacting their respective records bodies.
Gotta say, using 3 just feels like giving up due to laziness, even in 1200BC.
Also it's interesting how the Chinese entries basically stop between 1400 and 1949, whereas European names are far more present during this era. Some Japanese ones, too. I wonder how comprehensive this page is.
Rounding pi to 3 is just the engineering way. It's close enough to get the job done and then I don't have to worry about decimal places. However, using pi=3 typically undershoots your calculations, so personally I like to use pi=4
Sometimes zero decimals is enough precision even in 2025…
…but also because of laziness…
AFAIK the Chinese knew that the value between that of the encompassing shape that meets the circle at tangeants to the inscribed shape whose edges meet the same equidistant points gives us the approximation of pi. So did archimedes, and maybe even the babylonians.
So while a triangle yields about 3 and satisfies the theorem, you could also theoretically draw a 96 gon and 192 gon like Liu Hui for an accuracy of 9x10^5.
Personally I just memorize 22/7 or use the Leibniz infinite series if I have to.
Doesn't have the famous
ln(640320³ + 744)/√163
for some reason. Accurate to 14 decimal places I believe which is more accurate than what you need for 99.9% of its applications.
So to avoid memorizing a 15-digit number you'll memorize a 13-digit equation?
It's been said that with 15 decimals, you can calculate the circumference on the observable universe with a precision of the width of an atom.
14 decimal places is more accuracy than you'd ever need.
Consider the size of what you're measuring.
I'm American so you're getting SAE units, deal with it.
If we have a radius of 1", the circumference of my object is 6.283185 or so inches around. Maybe it's 6.283186. the difference between those two numbers is one one hundred thousandths of an inch. About 25 nanometers. Half the size of the smallest bacterium we've ever discovered.
That is with 6 decimal places. With 8 you can measure a circumference with an accuracy to the single atom. Any smaller than that, and you start charging the result by measuring it at all.
During lockdown I had a bit of time on my hands so I memorised all the digits of pi in the right order.
I memorized them in numerical order. First there's a bunch of 0s then a bunch of 1s, followed by 2s, and so on.
I took the opposite approach. All the digits of pi, in the right order, are 3.145926870.
Obviously I had to eliminate any duplicates otherwise this post would have been a lot longer.
Yeah but how many 0s do you have before you get to the first 1? I've been working on it but still don't have a definite answer.
You should do alphabetical next.
Hey, me too! I also did e and the Feigenbaum constant, though.
Yeah, me too. But first I had to count to infinite to make sure the decimal parts of these would fit.
Pi is exactly 3!
so 6?

Three, no more, no less. Three is the number of pi. Four should not be pi, neither two. Five is right out.
1, 2, 5!
3 sir!
Oh yes! 3!
I got into a long debate with someone who wouldn't accept my claim that pi is 3.
My reasoning was that 3 is accurate to the number of decimal places it's quoted to, which is all you ever can say of any given value of pi. Like, pi might not be exactly 3, but it's not 3.14159265358979323846 either, because both values still have infinity digits missing.
Does anyone else really want to write them now just to get an official rejection letter?
If I write them enough and get enough rejection letters, can I then get accepted as the Guinness World Records record holder for most rejections of Guinness World Record records?
Now I want to see the original letter. For some reason this reminds me of David Thorne (27bslash6)
Is there a Guiness world record for classes or categories of individuals with the most rejection letters from the Guiness World Records association?
If you pay for it I'm sure they would gladly add it

You could say he was all mixed up, and he didn’t know what (else) to do.
He bet on himself though
I like how the filename is "NoFair.webp". Hiding a funny little message in the filename is classy.
I don't remember if it was like ACT or whatever. I took it and I did terrible. I went to a class and they told me not to read the reading section, but just skim through it and grab key words. The the next time I did the test I did a pretty good job for my dumb arsre.
Pi for workgroups.
This isn't really a meme
Every 5y/o is better at copying the Guinness World Records logo.
Well, shit.
This guy beat me to it.
