  Electricity is the flow of ions, it's literally atomic science (albeit not "quantum" in the sense highly specialized sub field we know today).

    Ok but so is everything? The phrasing makes it sound like they were saying that the development of the lightbulb was through understanding of quantum mechanics (which, it of course was not).

      Only the LED light bulb. And then only kind of, they use approximations.
