Mine is this little tidbit about Khaki’s from https://www.heddels.com/2019/05/history-khaki-anything-drab/

“Tried and tested by all the major powers, khaki-dyed, lightweight cotton twills became the de facto uniform for any colonizing power. If you were going to ship your boys abroad to pillage and conquer someplace in the Southern Hemisphere, khaki was your go-to color.”

    How pineapples grow amazes me. Ofc if you’re from a place where pineapples grow, it probably sounds dumb, but I learnt that late in my life. Look:

    A pineapples plantation.

    Focus on a single pineapple, which grows on long leaves, on a long stem, alone, with other leaves on its head.

    Those fake astroturf fields and yards people are installing are actually quite toxic. In addition to heating plastic to high temperatures and baking it under powerful UV light each summer, the plastics and rubbers used for them are usually from sources like car tires which are full of PFAS to resist fires, wear, UV, etc. Those leach into surrounding areas whenever it rains.

    “Blue lights on train platforms in Japan have been shown to reduce the chance someone will jump in front of a speeding train. In fact, one study in the Journal of Affective Disorders found blue lighting reduced suicide attempts by 84%. It’s believed blue registers as a calming color, associated with the sky and sea, which may be soothing to people in distress, according to Psychology Today.”

    I guess people who keep using blue-light filter glasses at end of work will miss this.

    Not really a secret, but we don’t often think about it.

    Cash is fucking dirty. Here is the official Fedral Reserve estimated lifespan for each note:

    Denomination Estimated Lifespan*
    $1 7.2 years
    $5 5.8 years
    $10 5.7 years
    $20 11.1 years
    $50 14.9 years
    $100 24.0 years

    You can assume that something like a $5 bill might change hands on a weekly basis.

    So if you a $5 bill that still looks nice, it might be only 2 years old, so it might have seen about 100 owners up until now. It is said that 1 out of 5 people don’t wash hands after pooping.

    Your $5 bill is probably filled with poop, pee, sweat, food, cum, dirt, etc.

      I have one from the 50s/60s(?) that will gradually let two slices of toast up, but if you have only one piece of toast and you put it in the wrong slot, it will literally fly out of the toaster.

      I had to move the fridge after losing several pieces of toast between it and the counter before I learned what was going on. Was very confused about missing bread and the cat was a prime suspect.

    The first microwave ovens created were being used to gently re-warm frozen live hamsters, because when they tried to reheat the hamsters with conventional cooking methods, they heated unevenly and burned at the edges, which isn’t good for the hamsters.

        Modern ones do have hotspots and cold spots because of resonance and design tradeoffs, but I don’t think that was a problem for the hamster application. IDK, maybe they were structured a little more small and special-purpose, but regardless it was just penetrating radiation basically all throughout the hamster which is better than heating it from the outside in and having the heat having to conduct its way through the frozen tissue.

        Basically the same reason you can defrost meat in the microwave, but you can’t throw it in the oven to defrost more quickly without also cooking the edges.

          Microwaves also heat from the outside in. The difference is the heat can be turned on and off as easily as a light switch, whereas an oven is literally just a hot box. Defrosting works solely because the heat can be turned off for 14 out of 20 seconds (or what ever cycle the microwave has) to let the heat conduct through the frozen tissue.

          I wouldn’t be surprised if the hamster/rat defrosters achieved their results by simply being less powerful than a kitchen appliance.

            Microwaves penetrate a certain distance into the material and then turn into heat. Heat conduction from the outside doesn’t. I don’t know exactly what the average of that distance is and how it compares to the size of a hamster, but I would bet that it’s pretty competitive with the thickness of the hamster.

            Your whole argument here makes no sense at all. Having the ambient temperature set to the perfect defrosting value would work better than heating the skin of the frozen meat in cycles of full on / full off, if the microwaves were getting stopped right at the skin and then the heat had to conduct in from there.

                But you’re incorrect. Microwaves penetrate through many substances fairly well, mostly passing through them. The microwave ovens we use to cook are tuned to resonate with water molecules, and as a result the waves interact more frequently with those molecules. But in general, the waves just bounce around until they do interact with something, and it could be any particle within your hot pocket that it interacts with, not just the surface.

                All that is to say, microwaves do heat all throughout whatever you put in. Now, these waves can also excite particles and moisture in the air within the oven, and there is convection between the air and your hot pocket… But air is less dense than food, so convection will be secondary heating at best, and cooling at worst.

                  Yeah. They don’t penetrate an unlimited distance into the food, the center of some stuff won’t get heated. But they penetrate a lot further than the 0 distance that ambient heat from the outside does, conducting heat straight to the skin of the food and then letting it work its way in from there.

                  No idea what this person’s issue is, I sort of suspect that it’s just Lemmy in action, doing its thing.

                  So are you meaning to imply food, and especially live animals as being discussed here, don’t have significant water content? Because I have bad news for you: If it’s absorbed readily near the surface, it’s not getting much deeper.

                  Go ahead and try to “defrost” some meat on high. You will see that I am absolutely correct that the OUTSIDE will cook before the inside is defrosted.

                  Note that nowhere did I say it’s as inefficient as an oven, either, so if you’re imagining that’s what I said then you need to reread my posts. I merely described how the common misconception of microwaves heating things from the inside is incorrect. The outside will basically always heat faster unless it’s completely devoid of moisture, which is not the case what so ever in this context, nor in basically any context of “defrosting”.
