Carrick1973, in Magic π

There’s a 9 repeating 6 times in there which I’d think is a pretty rare occurrence in pi. I wonder what the longest occurrence of a repeating digit is.

chetradley,

Looked it up, and it’s apparently called the Feynman point after Physicist Richard Feynman (though the story behind that attribution is disputed). en.wikipedia.org/wiki/Six_nines_in_pi?wprov=sfla1

Carrick1973,

That’s fascinating. Obviously, there’s a series of repeating numbers in there, and one of the numbers would have a highest number of repeats… until further places of pi are determined and another number knocks it off… I assume there’s a repeating 1, or 2 that repeats 7 or 8 times,etc… at some point…

Pi is infinite so every combination/string of numbers is in there, if we calculated enough you could find a billion 2s next to each other

You can look through the first trillion here

Though it’s a bunch of downloading

Guest_User,

Not necessarily. It could just become a series of 1’s repeating forever. Nothing would require it to contain all strings of numbers.

If that happens in a number, then it is rational. Pi is not rational, so that will never happen in pi.

ILikeBoobies,

The point of pi is that it’s non-repeating

Guest_User, (edited )

At work at the moment so can’t go deep into it. But I think you misunderstand what non repeating numbers mean. Of course there are repeating numbers within pi which is fine, the issue would be if ALL the digits were to simply cycle over and repeat themselves. If however there are a few trillion digits then a series of 1’s and 0’s for ever, pi is still non repeating

ILikeBoobies,

Did you read what I responded to?

Guest_User,

I did read it, I also wrote it. Wasn’t trying to put you down or anything just sharing a bit of knowledge I found interesting. I know many people (my self included at one point) assumed pi would have to include everything when that just isn’t true. Apologies if I did a bad job explaining it though

ILikeBoobies,

I wasn’t clear then, it’s not that it has to

It’s that it can until calculated

Aermis,

On a long enough string I’m guessing… Infinite? Pi isn’t a pattern so does it follow the same “if monkeys hade an infinite amount of time to type at a typewriter they’d type Shakespeare”

Carrick1973,

Well I thought that at first, but it has to be less than infinite since other numbers have to repeat in there as well with at least some occurrence so it’s infinite minus something, but since pi goes on infinitely, it’s obviously some high number…

Still, we can’t proof that Pi^Pi^Pi^Pi is an integer or not, since we don’t know enough digits.

SparrowRanjitScaur,

It’s definitely not an integer seeing as it has a fractional component. Do you mean if it’s rational or not?

GenEcon, (edited )

No, we can’t proof if its an integer or not. If you can proof it, you are up for a great career in mathematics: www.spektrum.de/kolumne/…/2203268

(Unfortunately only found this german article, but maybe translation works)

SanndyTheManndy, in Magic π

I memorized it to a hundred digits for a bet so I’m set for life.

supercriticalcheese, in Biochem

Hmm object to the average chemical engineering work. We are mostly fancy plumbers, so we end up just sizing pipes and piping systems a lot .

Memory Masters destroying the last of their childhood memories so they can add another 80,000 digits of pi to their mind palace.

contextMemory Mastery is a technique where you force your brain to remember random information by formatting it in a certain way, some people have gone on to use this trick to memorize millions of digits of pi. A study recently came out confirming that every time you make a new memory it destroys an old one, so every time someone makes a “memory palace” it comes at the cost of older memories, such as in childhood.

hanke,

You wouldn’t happen to have that study close at hand?

I often nerd into new hobbies and learn new stuff. I also don’t feel like I remember as much of my early childhood as people around me does.

I have no idéa if this is what’s happening to me, but it’d be interesting to read about.

Omega_Haxors, (edited )

Sorry couldn’t find it and google is being as fucking useless as always 😔

EDIT: Found it, it was a youtube video youtu.be/diyoTo3Co08

exocrinous,

A study recently came out confirming that every time you make a new memory it destroys an old one

If that was true, babies would forget their first memory every time they remember their second memory. There’s no way it’s true. It might be partly true, but it can’t be completely true.

Omega_Haxors, (edited )

Well the way memory works is that it allocates certain clusters of neurons to storing information. When you’re young there’s a lot of blank space that you can store stuff in but as you get older you start having to pick and choose as more and more brain space gets taken up.

Here’s a cool video on the subject: www.youtube.com/watch?v=X5trRLX7PQY Fun fact: because of how memories are formed in chains you can tell if you’re on the precipice of forgetting something if you try to recall it and you start trailing into another memory. You can experience this for yourself by trying to recall the beat of an old song and note when it starts morphing into the beat of a newer song. It’s also worth noting that every time you recall a memory you destroy the original and rewrite it, bringing it back to the top. That little asshole is like 90% of the reason why our memories suck so much shit and are so prone to outside manipulation.

The worst? I stopped to do research after my PhD and now, I forgot everything. Dumb as a rock AND without any useful knowledge of my very peculiar subject.

But I still have the paper, yay!

netwren, in Magic π

Dope. I just memorized it to 50 digits. Good to know for my intents and purposes it doesn’t matter at all anyway.

EvilHankVenture,

Hey, cheer up, it doesn’t matter for anyone’s intents and purposes.

hansl,

No no no. The error compounds every time you math so if you math a lot at 40 digits you might end up with like 30 digits of correct precision. Totally unacceptable. Literally unplayable.

Gork, in Magic π

Diameter of a hydrogen atom is all well and good, but how many digits of pi will we need to be accurate to a Planck Length?

nova_ad_vitum,

Honestly probably not that many more. My guess since I’m too lazy to do the math is less than 100.

Malgas,

The width of a hydrogen atom is 3.1*10^24 Planck lengths. So, yeah, 65 digits of pi ought to do it.

EvilHankVenture,

The diameter of a hydrogen atom is over 10,000,000,000,000,000,000,000,000 plank lengths.

So based on this post I have no idea.

@xthexder@l.sw0.com avatar

Well that’s only 26 more digits, so we’re probably good at 100 digits of pi. [citation needed]

Mango, in Magic π

At work we have a scale sensitive to the 1/10,000 of a gram. 4 decimal digits. It’s so sensitive it needs to be encased in a box so tiny connection currents don’t make it go frantic! Even in the box the number changes a lot. 15 0s is nutty.

threelonmusketeers,

connection currents

Convection currents?

Mango,

Yes. Heckin Gboard.

Donjuanme,

Mine can tell if I’m sitting next to it’s desk or not. I’ve come to the conclusion it’s the deformation of the ground the desk is sitting on.

It’s really a silly amount of precision for what I use it for. But It’s so fun to lock g on .0000, even if only for a few seconds. Anyone who has a target of a specific amount of 0s can do it themselves. After the first 2 shits pretty random.

datelmd5sum,

And a hit of acid would show something between 0.0000 and 0.0002 on the scale.

Mango,

Not when I’m the detector!

Oh wait shjt j meant to reply to the meme abour pi digits that doesn’t make any sense

This meme didn’t show the revolving lab door, the giant corporate foot over the biochems head and the minimum wage employee who makes more money than them.
