Magic π

Even cooler, at 75 digits you can calculate the circumference of your mom
Joke’s on you, I only needed 69 digits to calculate the circumference of your dad’s cock
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
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.
connection currents
Convection currents?
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
I like to use 16, just to be safe.
It’s a bit far off. You should round down to 3 at the very least.
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?
Honestly probably not that many more. My guess since I'm too lazy to do the math is less than 100.
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.
Well that's only 26 more digits, so we're probably good at 100 digits of pi. [citation needed]
log_10(size of observable universe / planck length) = 61.74... so like 63 digits of precision for everything are enough
The width of a hydrogen atom is 3.1*10^24 Planck lengths. So, yeah, 65 digits of pi ought to do it.
Dope. I just memorized it to 50 digits. Good to know for my intents and purposes it doesn't matter at all anyway.
Hey, cheer up, it doesn't matter for anyone's intents and purposes.
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.
Still, we can't proof that Pi^Pi^Pi^Pi is an integer or not, since we don't know enough digits.
It's definitely not an integer seeing as it has a fractional component. Do you mean if it's rational or not?

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

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.
Math is just runes and you can't convince me otherwise.
So it's just a standard double precision floating point? Makes it seem like 15 decimal places was hand selected.
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.
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.

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

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

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

"Only" using 15 digits is still pretty insane
You get that level of precision in a standard "double" floating point number. So that's basically the normal level of precision you get without trying.
M_PI in math.h is like 20 digits. I'm surprised they just don't do that.
Google suggests that excel uses 15. So even college students working on any old STEM degree are probably using 15 digits.
I memorized it to a hundred digits for a bet so I'm set for life.
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
