### What does it mean "not to exist" for a number? Does the number 2
not exist? If it doesn't exist, is it equal to nothing?
Do chickens exist? If chickens exist, how do we know they do, while
the number 2 doesn't?
How come numbers "exist" in silicon, or gray matter but not in the
number of chickens?

### Some mathematical predictions of quantum theory have been
confirmed to the 7th or 9th (?) significant digit. Not only does
plasma count, it counts a lot.
