An *UN*watched quantum pot never boils…

We can’t say that it never boils, only that we don’t know until
measurement is taken.

Really though, quantum mechanics is really only useful in the realm of
the really small, and I don’t know about you guys, but I don’t think a
“quantum pot” would even contain enough food for me to bother thinking
about…

and if we sum over an infinite number of quantum pots? what about
then? in that case we could have a finite integrand, which means non-
infinitesimal amounts of quantum-food.

Moral of the story: a little knowledge is a dangerous thing source of much silliness.
