Wow! First time since February we went to a doctor's. Did you know they had thermometers that could take your temp from 15 feet away?

I am not joking. We went to Kaiser. Used hand sanitizer. Got a little sticky to put on and said our temperature would be taken. I asked when and they said it already happened! "It already happened" sez I? "WHEN?" They pointed to a contraption I hadn't even noticed as we walked by.

Was that developed because of the virus or have they had it for decades?

    They have been using them in public places like airports for quite a while.

    I was giddy with joy. Honestly it was so weird to me that so far away an electronic device could do that! I wonder what else is out there I know nothing about? I mean how is that possible E? How far can those sensors detect? Of course it makes a great deal of sense to have something like that but honestly it cheered me up and I have no idea why. I guess I'm desperate to find things that are cheery these days. Thank you for your reply m'dear! :)

    All warm bodies/objects radiate infrared, or heat. They have been used in the military for years to detect bad guys at night. They have now been calibrated to measure temperature. I don't know what their range is.

    I have no idea why it tickles me to know that E but it does. You're going to laugh but it's kinda sorta like quantum entanglement in my mind only on a much much much much much smaller scale. How can anything 15 feet away from me "read" me? How can a point here affect a point millions of miles away as if they are connected? It's all magic albeit on different scales. Finding that out made my day. I told the guy who was there that and he smiled. I guess he's used to old ladies saying wacky things. I guess science is my biggest fascination. Thanks m'dear! :)

    It is based on one of Einstein's discoveries...the photoelectric effect. He won a Nobel Prize for it.

    Oh something else I did not know! Thank you for the info E. Photoelectric effect. I'm gonna Google it! :)

    Oh yes, infra-red detectors, which is what these devices are, have been around for a long time, though it might be quite recently that they have been made sufficiently sensitive to measure people's temperatures to sufficient accuracy rather than just recognising their presence.

    (Infra-red radiation is heat energy.)

    I was gobstomped (in a very good way) by it Durdle. It just tickled me no end. If that isn't "magic" working right in front of my very own eyes I don't know what is! Thank you for your reply! :)
