      I noticed that the mirror was rolled out kind of like televisions in the modern world. He said at one point mirrors were in 70% of European homes, that’s about the number of televisions in 1960. Eventually there was a mirror in every room, now, we’ve got TV’s in nearly every room.

    • @artistjoh

      @@alphagt62 I doubt it was 70% of homes had a TV in 1960. I grew up on a farm and I still remember our neighbor getting one in 1963. It was the first one in the district and farmers came from miles away just to see the TV, and there was a big party. There were plenty of excuses to visit the neighbors after that.
      My father got our first one in 1964 so he could see the Olympic Games.
      When we went into town for supplies a couple of times a month it was always a long day that ended late and it was dark when we were heading home. We would see people gathered around the window of the electrical store. Whole families would be there, some brought folding chairs to watch the TV that would be on in the window. That didn't stop until the early 70's. That is why I would be surprised at 70% of homes having a TV in 1960. It might have been true in large cities, but was much rarer in smaller towns and rural areas.
      Being a rural area, TV was on for only a few hours in the evening, and because of problems with broadcasting equipment back then it was common for there to be interruptions of service, and a picture of a flower or something like that and the word "interlude" would be on the screen while a technician would diagnose the problem and replace a vacuum tube or something like that.
      There was always "snow" in the picture, but when it rained, or was foggy, or it was very windy there would be more snow than picture. We used to put one or two layers of cellophane over the screen as that helped with seeing a picture.
      In the early 70's I moved to a larger city, once I had a job, and bought myself a Sony Trinitron color TV and I left those days of unreliable television behind. The memory of it remains, but people who didn't experience the early days of television in rural areas don't realize how primitive it was.

    Early lasers made with rod-shaped emerald or ruby crystals required a finely- silvered mirror finish on the ends of the crystal; a pulse of light directed into the crystal would reflect back-and-forth inside the crystal from end to end and be amplified until finally it would burst through one end ofthe crystal without damaging the silvered surface. Hey, THG, how about doing an episode on the history of lasers?

      That myth about 7 years bad luck from breaking a mirror goes back to Roman times. The practice of covering mirrors when someone dies and the household is in the mourning is an ancient Jewish religious proscription that spread to other cultures and religions. Another part of that mourning process is not only covering mirrors and perhaps even turning them to face the wall, but may include flipping the mattress over on the bed. (Life begins in a bed ---- well, sometimes it does, and sometimes it begins in the back seat of a car 😉 ---- and often ends in a bed, so you flip the mattress over. Fortunately, no religion I know of says that you should flip the car over when somebody dies ! 🤔🤣🤣)

    topics taken-for-granted or mundane, like mirrors or screws, THG makes interesting, even fascinating! The only thing breezed over is the extensive use of mirrors in our technological world. Optics (even at wavelengths beyond human vision) are very important and mirrors are key to re-directing light rays in countless instruments. f.x. helioscopes: a telescope that studies the sun, uses a pool of liquid mercury 1 meter across rotated on a turntable to form a meniscus mirror form to reflect and focus an image at Sunspot Solar Observatory, New Mexico. Speeding it up changes the focal length. Very clever and worth mentioning.

      I smashed dozens of mirrors in a badly fire damaged house as a kid and my luck hasn't been particularly any better or any worse than anyone else's. If that old admonition was true that fire damaged house would have fallen down on my head. ( My best friend and I were given permission to take anything we wanted from the house prior to it being demolished, and so we had fun smashing every mirror in the place, of which there were literally dozens for some reason, as well as breaking all the windows.)

    1:52 If you're wondering why pieces like this are definitely _not_ polished to a mirror finish, you have to understand the concept of thermal cycling.
    Every day, the sun warms up the surrounding environment. Every night, things cool off. There are 365 days in a year, so a 500-year old object has seen the sun rise and set 182,500 times or more.
    When you heat up an object, it expands slightly, and it contracts when it cools. Many objects, but especially that made of stone, will experience a tiny amount of flexing during these expansion/contraction cycles which work themselves into mircrofractures that will, over the centuries, cause the surface to flake away.
    This is the reason modern museums keep artifacts enclosed in climate-controlled display cases: To maintain a constant temperature and mitigate any further thermal cycles on the artifact.

    Lacking clean horizons for celestial navigation, on expeditions to the North Pole the following procedure was used: set up a shield from the wind, light an alcohol stove, place a bowl of frozen mercury on the stove to melt it. Then the marine sextant was used to measure the angle between the sun at what is know as Local Apparent Noon (the sun at its highest in the sky and the reflection of the sun on the surface of the mercury. The molten mercury was self-leveling and reflective, just what was necessary. With the sextant angle, a chronometer, and a book of sight reduction tables the position in latitude and longitude could be calculated. Mercury freezes near 38 degrees below zero F.

    The history of "magic" mirrors in movies and books, as portals to other dimensions, could almost get it's own episode. Through the Looking Glass, aka Alice in Wonderland, is one such, but was it the first or were there earlier novels that used a mirror portal as a plot device?

    When mentioning the technique for coating telescope mirrors, the telescope shown is actually a refractor design, which uses only lenses and contains no mirrors. However, it's an understandable incongruity, since in the photo the scope's optics are hidden from view.
