    Dry bulb is the temperature independent of humidity. Wet bulb is has a wet cloth on the thermometer bulb. This simulates how much sweat cools you in the current humidity and wind.

    Measuring humidity instead and cross-referencing to get heat index is more common these days, but IMO it’s worse. 120 in the desert vs 120 heat index due to humidity is the difference between someone using a hair dryer on your face and getting cooked in a steam room, and it doesn’t consider wind and cloud cover.

    100F was defined as the human body temperature (The guy they used had a cold or something so it’s off by a degree and a half.)

    That’s useful for perception of heat. When the dry bulb gets above 100F, wind only cools you down by sweat evaporation, and when the wet bulb gets above 100F, even that can’t cool you down, and you will die if you don’t get to a cooler or drier environment.

    This is more intuitive than 36.5C.

    But really it is much better for human temperatures.

    It’s just intuitive, 0F is 100% cold, and 100F is 100% hot.

    When the dry bulb gets above 100F, wind only cools you down by sweat evaporation, and when the wet bulb gets above 100F, even that can’t cool you down, and you will die if you don’t get to a cooler or drier environment.



  • Korea

    The Korean War included the greatest retreat in US history, which was only stopped because we were fighting an enemy with barely any industrial capacity to resupply troops, or even supply them with enough radios, and we failed to achieve the objective of a unified Korea (letalone the bloodthirsty moron MacArthur’s objective of invading China and becoming the “ceasar of the east”).

    Kosovo, Yugoslavia

    We bombed a bunch of civilians, showed the world that our B2 stealth bomber could be shot down by 30 year old, man-portable AA. I’m still unsure what strategic use bombing embassies and apartments was.

    Greek civil war, Afghanistan Russian war, Arabian Israel wars

    America didn’t didn’t directly fight any of those.

    the war of 1812

    We lost that one, our objective was to take Spanish America, and we failed that. They also burned the whitehouse.

    WWI, WWII, Spanish American war

    Those the US did manage to achieve some of it’s objectives, but WWII was 80 years ago.

    American civil war, and the American revolution

    Those were primarily against other Americans.



  • What is the count of those vs. the number of surrendered Russians being treated well?

    There is no credible data.

    Which one is more likely to be in the news?

    Neither, I live in America, the news only intentionally covers Russian war crimes. I say intentionally, since I remember a CNN segment near the start of the invasion where armed Ukrainian soldiers jumped out of an ambulance in the background.

    The opposite would probably be true if I lived in Russia.

    Which one is more likely to be spread around by Russian bots?

    I assume it’s not Russian bots posting Ukrainian drone footage to the combat footage sub.

    Which will be more likely to be suppressed?

    Well I haven’t seen any news covering Ukrainian war crimes and I’ve seen plenty of news covering Russian war crimes, and I know it’s not because Ukraine isn’t doing any war crimes.

    The reverse would probably be true for someone living in Russia.
