This question already has an answer here:
I've always wondered this but never asked. Given this statement:
Energy can be neither created nor destroyed.
Should it be or or nor? This is on Wikipedia so they are probably correct in saying nor but why is this so? In my opinion it sounds like it should be or.
The more I think of it the more I think it can be left up to interpretation or emphasis. For example, it could be interpreted to mean:
Energy = ¬Created ∨ ¬Destroyed
Energy = ¬(Created ∨ Destroyed)
Some help here?
