Snail, I don't remember my chemistry all that well, but I think there IS a lot of sense in the way that hydrogen and oxygen combine.

Something about free electrons, and those electron gaps being filled in a stable fashion when two hydrogens combine with one oxygen; and in a less stable fashion when one oxygen and one hydrogen combine.

And the way we can predict new elements from the Periodic Table before we've actually discovered them.

This is stuff that is explained through deductive reasoning, through logic - no? It's a systematic way that things interact, not random.
