I state these as assumptions but they are really questions. Please correct.

- Entropy is usually applied in a thermodynamics context, but it can be applied to any other source of order just as easily.
- A deck of cards can have its entropy measured.
- A fresh, sorted deck of cards has the lowest entropy possible, as it is in the highest ordered state possible.

- The "order" of a deck of cards is entirely arbitrary. There's nothing objective about sequential human symbols.
- I could just as arbitrarily decide that the property of interest isn't sequential printed numbers, rather - I dunno - weight. The deck of cards is at its lowest entropic state when they are sorted heaviest card (most ink) to lightest card.
- I could even leave the property of interest the same and arbitrarily decide what is ordered and what is not:
- I start with a sequential deck of cards. I decide they are ordered.
- I shuffle them, and measure the disorder.
- I then
*declare the new state to be perfectly ordered*, and shuffle again.
