There have been a number of Scientific discoveries that seemed to be purely scientific curiosities that later turned out to be incredibly useful. Hertz famously commented about the discovery of radio waves: “I do not think that the wireless waves I have discovered will have any practical application.”

Are there examples like this in math as well? What is the most interesting “pure math” discovery that proved to be useful in solving a real-world problem?

    A good friend of mine from high school got his physics PhD at University of Texas and went on to work in the high energy plasma physics lab there with the Texas Petawatt laser, and a lot of the experiments it was used for involved plasma turbulence and determining what path energetic particles would take in a hypothetical fusion reactor.

      Be honest, how many unofficial experiments were there?

      You ever just start lasering shit for kicks?

        Probably not as many as we’d like to think. I recently got to run a few days of tests at Lawrence Livermore National Labs with an absurdly massive laser. At one point we needed to bring in a small speaker for an audio test. It took the lab techs and managers about two hours and a couple phone calls to some higher ups to make sure it was ok and wouldn’t damage anything. There’s so much red tape and procedure in the way that I don’t think there’s an opportunity to just fuck around. The laser has irreplaceable parts that people aren’t willing to jeopardize. Newer or smaller lasers are going to be more relaxed. This one is old enough to be my father, and it’s LLNL’s second biggest single laser iirc. And they are the lab using lasers for fusion, so they have big lasers.
