Anyone with an ounce of intellectual curiosity.
Out of fairness to the poster, I’ve gone my whole life without wondering about this.
Though I sometimes wonder why there are no “B” batteries.
Not many on FR.
Anyhow, 52! is another really cool number.
What is that number, you might ask?
52! can also be written as 8.0658175e+67.
Most of us would know this number as the possible combinations when shuffling a deck of cards. It is a number that is so massively huge that it is unlikely that any two decks of cards, ever, in all of humanity, have been shuffled the same, or ever will.
I was curious and looked it up. Most on FR would ask, "Who cares?" I cared.
“Anyone with an ounce of intellectual curiosity.”
I have an ounce or two. BTW, how many Protons in the Universe? Don’t know? Wow, I guess nobody has an ounce of Intellectual Curiosity...
