> Was Edison's invention of the light bulb not science because Thomson hadn't discovered the electron yet? Umm... yes it wasn't? Invention of a light bulb was not a scientific discovery.

You can invent something useful by bruteforcing through many trials and errors or even by just plain luck, without creating any new scientific understanding along the way. (Btw Wikipedia does not even regard Edison as a scientist.)
