Supporting Member Than_Bogan Posted September 12, 2018 Supporting Member Share Posted September 12, 2018 This really couldn't be any more off-topic, but the million seconds and trillion seconds references in another thread reminded me of some numbers-intuition things that I find kinda cool, and that eventually leads to a mildly-mind-blowing fact. Just for fun, I'll start this with a poll. Please don't google or try too hard to figure it out, just vote with your intuition. Which number is larger: The number of possible orderings of an ordinary deck of playing cards or the number of possible states of a Rubik's Cube?

Supporting Member Than_Bogan Posted September 12, 2018 Author Supporting Member Share Posted September 12, 2018 Answers: . . . . . . . . . The number of states that a Rubik's Cube can reach (without taking it apart) is 8! x 3^8 x 11! x 2^12 or about 43 quintillion or 4.3 x 10^19. So that's kind of a lot :smile:. The number of possible orderings of a deck of cards is "simply" 52!, which turns out to be about 8.1 x 10^67. So the correct answer to the opening question is that the deck is more than 1M times more. BUT I purposely misled you a bit with the choices. In fact, the number of states of the cube is approximately zero when compared to the number of possible deck orderings. Don't believe me? Try adding the smaller of those numbers to the larger one on your calculator and notice how it doesn't change. Your calculator doesn't display 48 significant figures, so you can't even observe the contribution of such a tiny number as 43 quintillion... Put another way, the deck of cards has more than a million million million million million million million million million times as many possible orderings as the Rubik's Cube has possible states. But that's not the mind-blowing part, which I'll dedicate a separate post to. Link to comment Share on other sites More sharing options...
Baller riplash Posted September 12, 2018 Baller Share Posted September 12, 2018 Are you including the Jokers or just 52 cards? Link to comment Share on other sites More sharing options...
Supporting Member Than_Bogan Posted September 12, 2018 Author Supporting Member Share Posted September 12, 2018 So that was all build-up to emphasize just how obscenely large 52! is. A consequence of this ridiculous number is the following fact: If you take an ordinary deck of cards and properly shuffle it so that the ordering is completely random, it is essentially certain that that exact ordering of a deck of cards has NEVER occurred before.

Supporting Member Than_Bogan Posted September 12, 2018 Author Supporting Member Share Posted September 12, 2018 @skidawg Good point. I meant to include "Who gives a rat's ass?" but then I forgot and apparently polls can't be edited. Link to comment Share on other sites More sharing options...
Baller Andre Posted September 12, 2018 Baller Share Posted September 12, 2018 @Than_Bogan I know you don't smoke weed...but you should really think about it. My ski finish in 16.95 but my ass is out of tolerance! Link to comment Share on other sites More sharing options...
Baller BraceMaker Posted September 12, 2018 Baller Share Posted September 12, 2018 Rubics cube seems really random till you remeber that all the corner peices have 3 colors, all the edge between 2 colors. Link to comment Share on other sites More sharing options...
Supporting Member Than_Bogan Posted September 12, 2018 Author Supporting Member Share Posted September 12, 2018 @Andre Interesting. One of my greatest influences in skiing AND one of my greatest influences in my career are unabashed pot-smokers. Never had any appeal to me -- perhaps because I'm just naturally that stoned...

Baller ScottScott Posted September 13, 2018 Baller Share Posted September 13, 2018 I only voted to see how many people voted. Was thinking it might have only been 2, as only 2 people that commented actually voted. Link to comment Share on other sites More sharing options...
Baller RazorRoss3 Posted September 13, 2018 Baller Share Posted September 13, 2018 Modestly entertaining permutation question, Permut(x,x) in Excel makes pretty quick work of it. Modestly interesting meaning more fun than work ;) For the record, the North does Freeze, but it hasn't yet, still a few months to ski. Which is good since my scores have been a scatter gun this year with everything from missing my opener to 5@35... Link to comment Share on other sites More sharing options...
Baller ScarletArrow Posted September 13, 2018 Baller Share Posted September 13, 2018 My son is a cubing nut, so I actually knew the 43 quintillion number... I picked that as my (wrong) answer, I mean what could possibly be higher than that!? As an aside but still numbers related, I just introduced him to Chuck Norris jokes - and his favorite by far is that "Chuck Norris counted to infinity, twice." Which leads me to a question I've never thought of - how would Chuck Norris solve a 3x3 cube? Don't @ me bro - this whole thread is off-topic!

Baller_ Bruce_Butterfield Posted September 13, 2018 Baller_ Share Posted September 13, 2018 “How would Chuck Norris solve a 3x3 cube?” Geez that’s too easy. With a side kick of course. If it was easy, they would call it Wakeboarding Link to comment Share on other sites More sharing options...
Baller Lars Posted September 13, 2018 Baller Share Posted September 13, 2018 Ok @Than_Bogan I'll play, I did get the poll right since I knew a bit about this. a fun way to picture it that I've read... Say you can shuffle a deck once a second. Pick a spot on the equator of the earth, and take one step every billion years (all while shuffling every second). When you make it all the way around the earth, remove one drop of water from the ocean. Do the same thing until the ocean is empty. Once you have the ocean emptied, law down a piece of paper flat on the earth, then fill the ocean and start again. Continue this process till your stack of paper reaches the sun. Guess what? Your number of shuffles still hasn't gotten to the left most digit of that number. Link to comment Share on other sites More sharing options...
