The discussion revolves around the memorization of Pi, with participants sharing their personal experiences and the number of decimal places they can recall. One user boasts memorizing 150 digits, while others mention knowing fewer, often citing practical reasons for not memorizing more, such as calculators providing sufficient precision. Some participants view memorizing Pi as a fun challenge or a mental exercise, claiming it helps improve memory skills. Others express skepticism about the usefulness of memorizing such a long string of numbers, suggesting that time could be better spent on more practical knowledge. Various mnemonic techniques are discussed, and some users share humorous anecdotes related to their experiences with Pi. The conversation also touches on the broader implications of memory exercises, with some arguing that the act of memorization itself can be beneficial, regardless of the specific content. Overall, the thread highlights a mix of enthusiasm, humor, and practicality regarding the memorization of Pi.

https://www.amazon.com/dp/0802775624/?tag=pfamazon01-20 includes one million digits of pi :biggrin:

But in case you need just a few, here are the first ten thousand digits: - http://www.joyofpi.com/pi.html -

and you're in good company - http://www.joyofpi.com/pilinks.html


I had a friend in high school who memorized \sqrt{2} to 200+ decimal places, because e and pi were to mundane. He used to come up to me at my locker and start reciting. :smile: We still keep in contact after 35 years.

I'm another 2 person -- there's too much other things to be doing to go any further :-p
 
  • #33
I have remembered so many digits of pi that I can't recall the exact count.
 
  • #34
I can remember all the digits but not necessarily in the correct order.
 
  • #35
up to 50 digits

since my ast post i have memorized more digits, the last time i posted i told you i can remember up to 32 digits. I can now receit the first 50.

I had a math teacher that said in grad school he memorized digits of pi to compete with one of his friends. Personally I know 3.14159
 
  • #37
who wants to make a wager...the bet will be " who can memorize the first 100 decimals of pi before the other person" lol
 
  • #38
I just say \pi. No worries about precision
 
  • #39
I say 3.14159265 but then I screw up and say 7 every time even though I know it's wrong. it's just stuck in my head that way. In a pinch I can recite pi to 3000 digits since no one I know can check whether I'm wrong or not

I just carry with me a gigantic wheel and a ruler at all times. ... this thread should be re-named "the official pi lame-joke-O-rama thread" :smile:

MY joke, Kurdt. That's MY joke!

In 10th grade I had a 12 digit calculator (1980's HP, the "sideways" kind). If you multiplied pi x 1000, then subtracted 3141, you got an extra 3 digits, for a total of 15 digits. I never bothered to memorize any more than that:

Thats what happens when ancient threads are resurrected. I can't be expected to read all posts :-p

Anyway it was a rather awful rip off of http://www.youtube.com/watch?v=JQNYUJIW4sw".

and he's still reciting?

At last count, I remember somewhere around 200 digits of pi.
 
  • #45
It has a three in it, right?

hahahaha :smile::smile:

Yes - he still does it, but he's not quite so serious about it.
 
  • #50
Have you ever checked him? once you get three or four digits in you could make it up and no one would know. It's easy to fake being a genius, look at Smurf. I know a guy who mumbles numbers all the time.

I once gave him a piece of paper with \sqrt{2} to 100+ decimal places. He would have me stand there reading the paper while he recited the number - he didn't fake it. He is now responsible for integration of instrumentation and protection (reactor safety) systems in modern nuclear power plants.

Tell him to give up on the number and try reciting safety procedures in case of a melt down. priorities man

Just to be a complete *******, I'm going to resurrect this post.

By the way: 3.141592653589793238 (18 digits)

Congratulations, I think we have a winner!

:rolleyes:

Does 10π count?
 
  • #57
No, Jim, 10π doesn't count. XD
 
  • #58
I used to have a mnemonic system (thanks to my two study hall periods a day in tenth grade), and I ended up memorizing it to about 30 digits. The only ones I remember now are 3.1415926, which is still more than I'll ever need to use...

3.14159265358979

365.24219878

as a lysdexic, I got very po'd memorizing these silly numbers only to find myself getting the last four digits mixed up at the ripe old age of 10. I gave up.

Then in college I discovered you were not supposed to list accuracy past a certain point because it was pointless.

I was very happy that I stopped.
