So in essence since science is a subset of magic that works and magic that doesnt work isnt magic, then using math here science is equal to magic as the part that isnt magic was just subtracted and all we have left is science is nothing more then magic.
Thereoms can be used to prove anything when you create the statements that theorems are based off of
edit: if science IS nothing more then magic then magic can be more, but not always. Then "science" is subset of magic. Now what the subset is is still up in the air. So this statement is valid since science is based on understanding which means that it can be more, but may actually be equal to science. We will always have people who dont understand so we cant have science without magic as the thing that is science will always start with magic.
