Question

It is for a homework assignment in school.

so i guess you can say english is not science right!

Answer 2

what ever can not be tested and re tested, or whatever can not be proven by mathematical explanations.

Answer 3

nothing

simple as that

Answer 4

Strictly speaking, anything which can't be falsified.  If I tell you there's an invisible chair in the middle of the room that can't be detected by any means, can't be touched, and can't be moved, there's no way to prove that statement false.  It is, therefore, not science.

In my personal opinion, I would quote John Campbell:  If it can't be expressed mathematically, it's not science.  It's opinion.
