  • Yeah, if the cable impedance is small enough that you can still get the volume you need it doesn’t matter

    The comment above is informed by radio electronics - in 1980s Australia had TV on low enough frequency that we used balanced wires (two parallel conductors, like speaker wires) for best interference rejection, with opposite voltage in each conductor and interfering signal will affect both conductor equally and opposite, cancelling the interfering signal (we also needed a “balun” on the antenna to match between the balanced wires and the unbalanced antenna)

    Now every antenna you see on roofs and wifi devices connect with coax cables and connectors which are impedance matched to the antennas because impedance really really matters at microwave frequencies, those cables need shielding as they can’t reject interference in the way balanced cables can




  • Same person, I don’t know how people here don’t get that a quantum physicist might not keep up with news about people, don’t we all know people on the spectrum? He gets invitations to Epstein’s parties because Epstein liked hanging out with physicists, people are suspicious because he continued attending those parties after news was out about how bad Epstein was.

    I’d be surprised if I had heard that a mathematician read the news, and if they did that they read about people in the news
