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

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

[–] [email protected] 0 points 9 months ago

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

[–] [email protected] 0 points 9 months ago

At my last job I was bored so I wrote sql server functions to perform standard math operations on varchar(max) and used them to build factorial tables which I then used to iteratively calculate pi. I think I got up to around 100 digits before I got yelled at for bogging down the server and had to stop.

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] 0 points 9 months ago* (last edited 9 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

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] 0 points 9 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] 0 points 9 months ago (2 children)

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

[–] [email protected] 0 points 9 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. :)

[–] [email protected] 0 points 9 months ago

but obviously doesn’t contain all numbers with finite digits.

I was just claiming possibility because we haven’t calculated the infinite string

[–] [email protected] 0 points 9 months ago* (last edited 9 months ago) (1 children)

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

[–] [email protected] 0 points 9 months ago (1 children)

Did you read what I responded to?

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

[–] [email protected] 0 points 9 months ago (1 children)

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

[–] [email protected] 0 points 9 months ago

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

It’s that it can until calculated

[–] [email protected] 0 points 9 months ago

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"

[–] [email protected] 0 points 9 months ago

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

[–] [email protected] 0 points 9 months ago

Haha 3 go brr

[–] [email protected] 0 points 9 months ago* (last edited 9 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.

[–] [email protected] 0 points 9 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] 0 points 9 months ago* (last edited 9 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

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.

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.

[–] [email protected] 0 points 9 months ago* (last edited 9 months ago)

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: https://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.

[–] [email protected] 0 points 9 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.

[–] [email protected] 0 points 9 months ago (1 children)

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

[–] [email protected] 0 points 9 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.

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] 0 points 9 months ago (2 children)

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

[–] [email protected] 0 points 9 months ago

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

[–] [email protected] 0 points 9 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] 0 points 9 months ago* (last edited 9 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] 0 points 9 months ago

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

[–] [email protected] 0 points 9 months ago (2 children)

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] 0 points 9 months ago

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.

[–] [email protected] 0 points 9 months ago (1 children)

connection currents

Convection currents?

[–] [email protected] 0 points 9 months ago

Yes. Heckin Gboard.

[–] [email protected] 0 points 9 months ago

I did not know that and that's crazy awesome!

[–] [email protected] 0 points 9 months ago (1 children)

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

[–] [email protected] 0 points 9 months ago

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

[–] [email protected] 0 points 9 months ago

I like to use 16, just to be safe.
