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

    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.

      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.

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

    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?

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

        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.

    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.

        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…

      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”

        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…

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

    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.
