I memorized it during the summer of 2010 when I was completely out of anything to do. I don’t keep it memorized anymore, it is too big for me to memorize and I’ve never written it down, though I have often looked it up. I like that number but I don’t really use it. I can probably put that in the same category as those people who memorize prime numbers for fun. I am not especially proud of my memory.
those are technically digits of pi
just
in a different order
Yeah, like, 2770006788276314.. is just a different way of writing
22/7 x 3.1415926535 ..
as is 2646019185456846..
Actually, tumblr user raining-anonymously, they are in completely proper order. They are just located in a random position within the full digits of pi. 🤓
This is true! My counterexample above was pretty poorly chosen.
If you order the digits of pi properly (meaning by their natural ordering within the decimal expansion), you will find that 27700067882763149… is indeed the 2646019185456846 right after the decimal point.
Actually we don’t know if that sequence is anywhere in pi. I tried on various sites where you can search pi and none of them found it in whatever amount they search, but of course that doesn’t mean anything. We don’t know if pi is normal, so contrary to popular belief we don’t actually know if every sequence of digits is somewhere in pi. It could, for instance just run out of 5s eventually or something. Pi is probably normal, but until we know for sure we cant say if those digits are in it
