Pi Memorization!

Post Reply New Topic

3.14159265358979323 is all I really kept it to.

My favorite thing about pi is the Euler identity atm.

Though, I would like to learn pi to the Feynman Point.

Named because Richard Feynman said he wanted to memorize it to that point so he could rattle it off to a class, then quip "nine nine nine nine nine nine, and so on."

Improved mine just a little with all the tinkering I've been doing with numbers, surprised a cashier cause she gave me 3.23 in change, I went "huh, pi is 3.14159265358979323846, weird"... she kinda didn't know how to respond to that, lol.

Also e is 2.718281828... damn, I have it to 20 as well, but sometimes it slips.

edit: caught a typo, dunno why I put a 6 in there before the 323, doesn't happen when I recite it out loud... strange, but I'm used to writing it in courtney's modern now.

I used to know it to 65 decimal places, I can't remember why I stopped. Then I planned to do it again starting last month, I obviously forgot to do so since this thread just reminded me. My first target is 1'000 decimal places. I don't really have a reason to do this, probably whenever I'm bored or for the sake of memorizing series of digits.

All I know is pi equals 3.14.

I can, however, recite the alphabet backwards.

Make a song of it:

zee why eks double-you vee you tee ess are que pee oh en em el kay jay eye aytch gee eff ee dee cee bee ay

I personally think e has more geek cred, or e^pi and pi^e to like 10 digits would be cool too.

I spent a couple of minutes memorizing it to 15 decimal places when I was bored in high school, never felt a need to expand from that (I like the total number of numbers, 16, too).

I get tired after eight decimals.

You guys are full of talent.

I don't know about numbers, but I have memorised Pi to 2 letters.

i've never tried to memorize pi, but it appealed to me when my maths teacher reeled off some to the class when i was at school. i memorized a whole deck of playing cards around that time. i reckon i have a knack for memorizing those sorts of things. i'm very good with phone numbers, and know my bank card number by heart too. i even remember cheat codes from computer games i played more than a decade ago.

two years ago i tried to memorize it up to at least 15 but found something else to something obsess about.

I agree the majority of my time is better spent. but why not study pi? surely there are some things you do, watch television, or other indulgences in entertainment that are not particularly 'useful'. use some of this time to study pi. If anything it becomes a nice conversation piece as to what the purpose of it is, or if there really is purpose in anything.

I have been working on pi for about a month. the majority of my instances of actually sitting down and committing more to memory could probably be translated only a few hours of actual work. I wish i had more time for pi. so far 88 digits.

going to try again then go back to bed.

planning on going at least to the feynman point. 3 digits past actually. 999999837. 8 steps down from 9, 37 is a nice prime number. this is 770 digits, guess i may as well do at least 777, or 789. my short term goal as of now is to the next 141, this would be 297 digits total. the first time the sequence of the first 3 decimal digits reoccurs

ok try go get an hour of sleep before i have to get up again to go to work

i have a question. when the digits of Pi are memorised, is a person just memorising one numerical representation of Pi? i always wondered about that - i think i remember hearing once that every representation we can make is just an estimate.

Kate Bush did, in the song Pi, but either skipped some lines or had a chunk of vocal cut in the release.

Pi is Pi. It is the same number. It has an infinite number of decimal places. No computer is capable of calculating all the decimal places simply due to the number being infinitely long. It is known accurately to several million decimal places, maybe more nowadays, but it will never be completely known.
