Waldo 96 #1 Posted September 15, 2021 Assuming the statement below is true, and there are 133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 atoms in planet earth; how many planet earths would you need such that each atom in all the planets, represented one combination, out of all the possible ways you can shuffle a deck of 52 playing cards? Go!... Quote Earlier today I received a reader-submitted question from Bryan in New York. He asks, “How many atoms are there on Earth?” Whether purposefully or not, Bryan has asked a very difficult question, and one that is nearly impossible to answer exactly. But, thanks to science, we can estimate. According to the US Department of Energy’s Jefferson Lab, the answer is: 133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. That answer comes from an estimation of the number of atoms in each of Earth’s elements, like Iron, Oxygen, Silicon, Magnesium, Sulfur … etc. Adding them all together, we get a number that works as an estimate. https://headsup.scoutlife.org/many-atoms-world/ Share this post Link to post Share on other sites Share this content via...
Waldo 96 #2 Posted September 15, 2021 (edited) I've worked it out... Spoiler 606,452,444,894,314,876 earths. Next time you shuffle a deck of cards, there's a pretty good chance, no-one will have ever had that specific combination before, or ever will again.

Mr Bloke 1,445 #3 Posted September 15, 2021 Hmmm... I'd say 52! (factorial) divided by that big number! Am I correct? Share this post Link to post Share on other sites Share this content via...

Waldo 96 #6 Posted September 15, 2021 (edited) Also interesting (well, at least to me), 52! is even more than 2^256 (i.e. the number of possible private keys on the bitcoin network). Apologies, the above was incorrect. I ran out of fingers and got it all wrong. Silly me! Edited September 16, 2021 by Waldo Share this post Link to post Share on other sites Share this content via...
