Upon pouring water into a pot, setting the pot upon the stove and turning the burner on (after the waterline break somewhere downpipe): if you forget about it, the water goes away. You come back to and empty and hot pot.
But does the water really go away? Theological implications… transubstantiation of molecules… or did the water ever really exist in certainty, was it only in flux to begin with?
Whatever. The pot is scalding. This means something.
