The Importance of Verification in Science

Every verification, if you invert it, is a refutation and vice versa. It's okay to word it either way because logically they're just inverses of each other. But that's not true for like Newton's theory, right? This is what Deutsch brings out  is that Newton's theory is something so complicated that the inverse of Newton's Theory is not Einstein's theory. So there it is. Popper really just didn't have a problem. Also something else that gets missed. Whenever we falsify a statement, we therefore automatically verify its negation where the falsification of a statement can always be interpreted as the verification of its negation.
