    If you think about it, almost all computer-technology is radio. Wifi, bluetooth, GPS, radar, and cellular are literally radio. Meanwhile everything else runs on transistor tech developed and refined… for radios.

    Our modern economy couldn’t exist if people like Hertz and Maxwell didn’t get to toy with their useless hobbies. But we can’t rely on the curiosity of the leisure class anymore. Basic research is expensive, necessary, and a public good. I’m afraid that the Trump regime has already spoiled the secret sauce that makes America the technology leader of the world.

      Two inventions:

      • Internet
      • Computers

      are independent of each other, but go together nicely.

      You could have an internet (sort of) without computers. Consider Teletypers, FM Radio broadcasts, or Telephone.

        Really? You mean like the … telephone network?

      Even more than that, just proving Maxwell was right was a key stepping stone to all of modern physics. Maxwell, not Einstein, was the first to show that the speed of light is invariant, and Einstein’s Relativity was a framework for explaining how tf physics works if that’s actually true. Prior to Einstein, physists all just kind of assumed there was some flaw in Maxwell’s theorems to lead to this crazy speed invariance, but as the evidence just kept piling up in favor of Maxwell, they started having to wrestle with the uncomfortable thought that this could actually be true. In this sense, Hertz can also be thought of as an important step to Einstein and beyond, and almost all of our modern technology.

        It’s getting pretty drafty up here. Giants on shoulders of giants all the way down. I can’t even see the bottom anymore.

      Transistors were mostly developed for telephone systems (the ones with wires) as a replacement for tubes. And the modern tech used for radios is very different from that used for computers.

        Ithink you could be more charitable in your reply. Transistors were developed to replace tubes in telephone systems… Okay but the tubes had been developed to where they were because of their usefulness in radio.

        And while computers don’t inherently rely on radio, it’s radio communication that’s taken computers from one in every office to one in everyone’s pocket. Right? The main thrust of the previous commenter is true.
