  • Polycarbonate has one of the lowest ABBE values of any of the optically used plastics, so it scatters light pretty badly the thicker it is. As compared to eyeglasses, telescope lenses are really thick, so the poor light transmission would ruin the clarity. On top of that, poly expands a lot under heat, and so any coatings on the lenses will eventually start to craze and delaminate. Glasses don’t need to last more than 5 years before being replaced, so it’s not as big of a deal. If your telescope became unusable in that time, you’d be furious.

    Poly, while being impact resistant, is not nearly as scratch resistant as glass, and is nowhere near as chemically stable. Didn’t realize there was dirt on your cleaning cloth? Ruined scope. Cleaned it with regular window cleaner? Ruined scope.

    There are other resins that would be better, but nothing nearly as simple and durable as glass comes close to the optical clarity.

    Eyeglasses would still be made from glass if they weren’t so heavy and potentially dangerous, Not to ignore that nobody wants to wait two months for custom lenses to be made.

  • I run three offices, and I can tell you we don’t get any of that money. In fact we pay out the ass for whatever bullshit tech company was forced on us by insurance lobbyists to make you see those ads, while they also make the questionaires unreasonably long and uneditable so they can data harvest and make another dollar after tech fees, Ad revenue, service charges, and insurance payments.

    But we can’t just not use them, because every new regulation is a 60,000$ fine, and they send ghost patients at least once a quarter to try and catch violations to rules they lobbied to make as difficult as possible to conform to.

    My EHR system is 1700$ per month per office, and it has only made everything much slower and less personal, while forcing me to constantly do tech support for half of our patients.

    Hippa is supposed to protect us from the data harvesting, but since the insurance companies own the tech, device, ad, and service companies, as well as most offices, they don’t have to sell your data, because they’re the ones who want it.



  • Amother organism or person needs to be predictable to be trusted.someone or something acting in an unpredictable manner means it may suddenly decide you’re a threat. We evolved in a world before science and medicine, where any injury could mean death. Even the most unstoppable animals, bears, elephants, moose, will bluff charge a threat rather than immediately attack, because fighting risks injury, regardless of how unbalanced the fight is. I can’t win a fight against any of those animals, but I can bite it while it’s killing me. A full thickness bite wound is all but guaranteed to cause an infection, which may kill or disable.

    Humans are also social creatures, and we run on cultural norms that make it easier to trust that the person next to you in a restaurant won’t suddenly stab you, even though he is holding a knife.

    A major cultural difference can make others seem dangerous in a primal way. We know through interaction that other cultures are not more dangerous, but that primal unease of being surrounded by people from a different tribe is still in there somewhere.

    In my opinion, this is why racism is so hard to root out. A lot of it is taught by others, but it’s not a negligible amount tied to fear of anything different.
