  I thought pi hadn’t been proven to be normal, only conjectured to. My phone number isn’t in the digits of pi that we’ve discovered so far, for example: www.angio.net/pi/

    Plot twist: the websites that check if a given number has been found in pi are actually just data mining operations looking for credit card numbers and phone numbers.

      That did occur to me, so I only gave them my old number.

      There is a website that just has like, a million digits of py in plai text, you could go there and ctrl+f

    I checked a couple but none were found if I included the area code.

    Based on my sample size of half a dozen phone numbers, it doesnt seem to have numbers once they are more than 8 digits.

    Seems like there should some formula to determine how long the normal number needs to be to have all digits go to a certain length.

    Reminds me of the formula for calculating the shortest path to watch all episodes in a tv series in all possible orders.

      If you explore compression using pi - i.e., giving an index and a length of pi as your compression method - what you’ll end up finding is that the length of the data you want to compress is about the same as the length of the index in pi your data is at.

      So if you wanted to “compress” five digits by just linking to its index in pi, you would most likely need a five-digit index into pi to find the spot where pi has that number. So, you save nothing on average.

      There’s a good blog post that goes into this, but I’m having trouble finding it. The rough explanation I can remember is: if you have every permutation of a given length n in a row with an even distribution, then a random string you choose is likely to be in the middle of that length. Using our numbers 0-9 as our base, that puts you at index 10^n/2. Given our example of 5 digits, that’s 100000/2 - 50000, itself a 5 digit number, saving us no space.

      In the mean time, you can use pifs to “store” your data using similar ideas.

    Sorry for the AI slop. I am not an artist and just thought this was kind of funny. I like that Ω is hidden in her hairstyle.

    Pi is provably irrational

    • hakase@sh.itjust.works ⁨1⁩ ⁨month⁩ ago

      Yes, I’m aware of that, but I’m not sure how it’s relevant. There are an infinite number of irrational base-10 numbers that only contain combinations of 0 and 1, for example, and none of them will contain my phone number, credit card, etc.

      Not all irrational numbers are normal numbers, and only normal numbers are guaranteed to behave as described in the OP.

    is 200m what’s been discovered, or just what was worth putting into this program? Not a huge expert but I thought it’s all fairly easy to get the next number of pi, just seemingly never ending.

      We currently know about 202 trillion digits of pi. As for your other question: it is easy to get the next digit of pi from a “mathematical” point of view. By this I mean that we know functions that will approximate pi with as much precision as we want, but actually having a computer do it is very hard. The digits we know today took 3 months and needed 1.5 petabytes of high end storage.

      Apparently it’s been calculated to trillions of digits so a bit lacking.

      The search on that length would need an optimized index.

    Write speed must be atrocious, but I do wonder about the read speed.

    I bet there are algorithms which can compute arbitrary digits of Pi in Log time or less, and you could parallelize that to make data retrieval very fast.

    I look forward to the day where someone encodes Rick Astley’s famous hit, using 10 markers or less

  As if thats not bad enough, someone wrote an entire book that contains the exact date and manner of my death and put it in the library of babel.
