Hate math, so do I But one thing I shall say for the least I make: The variable of "a" equals itself. Same goes for English, with all the definition and all the fuss. A word does equal itself directly, basically a equals word and a equals a. Something being possible is, in fact, possible. Something being juicy is juicy. Something good is good. Something bad is bad. But what 'bout impossible. Something impossible is impossible. What does that mean? Impossible itself is impossible. This is the only thing math and grammar was useful to me: Learning that impossible itself is impossible; that everything possible. So if you say something is impossible, you just confirmed it's possibility.
