The Astonishing Number of Ways to Shuffle a Deck of Cards
Exploring the mind-boggling size of 52! and its comparisons to other vast quantities in the universe
Have you ever stopped to consider just how many ways there are to shuffle a deck of cards? It might seem like a simple question, but the answer is actually quite staggering.
A standard deck of playing cards has 52 cards, and the number of ways to shuffle those cards is referred to as 52! (52 factorial). This number is equal to the product of all the positive integers from 1 to 52, and it is an extremely large number. In fact, 52! is approximately 8,065,817,517,017,093,482,000,000,000,000,000,000,000. That's a number so big, it's hard to even write out in full!
To give you an idea of just how large 52!, consider this: there are only around 31.5 million seconds in a year, so there are more ways to shuffle a deck of cards than there are seconds in a year. There are also only around 10^18 to 10^19 grains of sand on Earth, and there are only around 10^27 to 10^28 atoms in the average human body. So, there are more ways to shuffle a deck of cards than there are grains of sand on Earth and atoms in the human body combined!
And if you think that's impressive, there are even more ways to shuffle a deck of cards than there are stars in the observable universe. It's estimated that there are around 10^22 to 10^24 stars in the observable universe, which is still significantly smaller than the number of ways to shuffle a deck of cards.
It's truly mind-boggling to consider just how large 52! is, and it's a reminder of the vastness of the universe and the complexity of even seemingly simple things. Next time you shuffle a deck of cards, take a moment to appreciate the endless possibilities that lie within those 52 cards.
As you can see, the number of ways to shuffle a deck of cards is truly staggering, and it's a reminder of the vastness and complexity of the universe. But it's not just the number of ways to shuffle a deck of cards that is impressive – there are countless other things in the universe that are similarly vast and complex.
