Even cooler, at 75 digits you can calculate the circumference of your mom

[–] [email protected] 45 points 8 months ago* (last edited 8 months ago)

Joke’s on you, I only needed 69 digits to calculate the circumference of your dad’s cock

[–] [email protected] 67 points 8 months ago (7 children)

Why would you miss the opportunity to make the web page continue computing pi to as many digits as you feel like scrolling down to expose though

[–] SzethFriendOfNimi 33 points 8 months ago

Whoa. No spoilers for Contact please.

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.

[–] [email protected] 21 points 8 months ago (1 children)

connection currents

Convection currents?

[–] Mango 9 points 8 months ago

Yes. Heckin Gboard.

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.

Haha 3 go brr

[–] [email protected] 34 points 8 months ago (2 children)

I like to use 16, just to be safe.

[–] [email protected] 3 points 8 months ago

Much more round than 17 at least

[–] hansl 6 points 8 months ago

It’s a bit far off. You should round down to 3 at the very least.

[–] netwren 25 points 8 months ago (1 children)

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

[–] EvilHankVenture 21 points 8 months ago (1 children)

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

[–] hansl 6 points 8 months ago

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.

[–] [email protected] 22 points 8 months ago* (last edited 8 months ago) (1 children)

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

[–] SparrowRanjitScaur 8 points 8 months ago (1 children)

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

[–] [email protected] 4 points 8 months ago* (last edited 8 months ago)

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: https://www.spektrum.de/kolumne/ist-pi-hoch-pi-hoch-pi-hoch-pi-eine-ganze-zahl/2203268

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?

[–] [email protected] 16 points 8 months ago (1 children)

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

[–] EvilHankVenture 23 points 8 months ago (1 children)

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.

[–] [email protected] 19 points 8 months ago* (last edited 8 months ago) (1 children)

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

[–] [email protected] 15 points 8 months ago

log_10(size of observable universe / planck length) = 61.74... so like 63 digits of precision for everything are enough

[–] EdibleFriend 17 points 8 months ago

Math is just runes and you can't convince me otherwise.

[–] Carrick1973 14 points 8 months ago (3 children)

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.

[–] [email protected] 23 points 8 months ago* (last edited 8 months ago) (1 children)

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 15 points 8 months ago (2 children)

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

[–] [email protected] 6 points 8 months ago

It could just become a series of 1’s repeating forever

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

[–] [email protected] 2 points 8 months ago (2 children)

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

[–] [email protected] 26 points 8 months ago (1 children)

Take a look at 0.101001000100001... This number is also non-repeating, but obviously doesn't contain all numbers with finite digits.

The property you're looking for is called to be a normal number. Pi is assumed to be one, but it hasn't yet been proven.

However, in a sense this is an unremarkable property as almost all real numbers are normal. :)

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

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

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"

So it's just a standard double precision floating point? Makes it seem like 15 decimal places was hand selected.

[–] [email protected] 10 points 8 months ago (3 children)

Why stop at 1 billion?... Let's go for a trillion, just because we can.

[–] [email protected] 16 points 8 months ago (1 children)

we do what we must because we can

[–] JusticeForPorygon 4 points 8 months ago (1 children)

For the good of all of us, except the ones who are dead

[–] qwertychomp 4 points 8 months ago

But there's no sense crying over every mistake

[–] [email protected] 3 points 8 months ago

Idk how much the original gif weighted, but a gif that's thousand more than that would be an absolute pain to load.

[–] SanndyTheManndy 6 points 8 months ago

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

[–] [email protected] 5 points 8 months ago

Just one more digit bro, imagine how many things youd discover bro, just one more, one more and it will be so much safer bro, It would help all mission just use 16digits bro
