    A lot of people think that to get to orbit, you just go up. That’s partially true, but in reality you go up to get out of the atmosphere, and then go sideways really, really fast.

    Imagine throwing a ball in the air. If you throw it straight up, then no matter how high you throw it, it just comes back down. Now imagine throwing it across the room. It falls in a curved arc, right? Now imagine throwing it so fast that it goes past the horizon. That curved arc is still there, and it’s much longer now.

    Now imagine throwing it so hard that it not only goes past the horizon, it actually never hits the earth in the first place. That’s an orbit! Of course, the earth has an atmosphere, so it would slow down because of aerodynamic drag. That’s why we send rockets way upward—to get out of the air.

    So a satellite in orbit is literally just falling constantly, but because it’s going so fast, it’s always missing the earth. It’s for this reason that an astronaut can’t “fall off of” the space station. They’re moving just as fast as the station is, and so even if they pushed themselves off of it, they would remain in orbit.

      “The Guide says there is an art to flying”, said Ford, “or rather a knack. The knack lies in learning how to throw yourself at the ground and miss.”

      But, without any thrust, they would stay in orbit for years. Eventually, if in low orbit, their space suit will collide with enough stray atoms, it’ll lose enough speed to fall back to earth and incinerate in the atmosphere.

    I may not know anything but as someone who knows something I can say that the thing is permitted.

    Sorry, I don’t have any experience in anything and I don’t know much about something. But I can type this: “GGKJDGgkjdsgakKGKJDGhkwGHJKKK”.

    Cool, huh? Alas, I lack experience, but I improve myself from time to time.

    I can even quit from vim!

    We are only 5 years ahead of a fungus that makes farmland unusable. And that 5 year gap is shortening every year because the fungus is evolving faster then our ability to genetically modify crops to combat it. This fungus is in almost every field in north America and is related to the fungus that took out the bananas in the past.

      Fusarium

      Doing some quick searching, I didn’t find anything that covers your scenario. Not that I don’t believe you, but do you have a source on Fusarium quickly evolving fungicide resistance in a big way?

        My source is working in the agricultural world and seeing the results in the field. We are fighting it but crop production is falling as we do. There are crops that aren’t affected of course but they don’t make the money which farmers need to live.

          It will be fun if we lose modern high yield rapeseed and soybean. Lovely.

          Unrelated but horrible farm story you reminded me of. Worked on a tater farm when I was a kid. One of my favorite things when riding the planter was when they would spray fungicide on the planting from previous days. It smelled just like Grapico cola (grape flavored soft drink). We all loved the smell of it and basically huffed the wind. Probably get dick cancer or something from it one day.

      I thought the 5 year fall was shortening every year because the years pass

        Nope, a newly modified canola strain has about 2 years before the fungus can overcome it. And a new strain needs to be introduced. And those new strains are getting harder and harder to produce.

    The stem on a wine glass has a purpose besides looking fancy. A wine drinker is meant to hold the glass by the stem so the temperature in their hand doesn’t affect the flavor profile in the wine. All wines have an ideal serving temperature also. It depends on the specific wine, but in general, reds are slightly below room temperature and whites are slightly above fridge temperature.

      "If you know that you know nothing, then that means you know 1 thing; which would cancel out the fact that you know nothing, making you a fool.

      The key is to recognize that you only know that you’ve more to learn about the things you do not know, though you don’t know what those may be. Only then can you never be mistaken in these regards."

      I read that on a fortune cookie once.

    In order to make sourkraut, you need cabbage, salt, a knife, a cutting board, a big bowl, a scale, and an appropriate storage container for fermentation.

    Start by rinsing the outside of the cabbage. Peel off any leaves that are damaged badly, cut out any smaller bad spots, then quarter each head, remove the core, and cut small strips. Weight the cabbage you have remaining, divide the weight by 50, and put that much salt together with the cabbage strips in the large bowl. Mix the salt and cabbage occasionally, and either punch it, or squeeze it. After 2 - 4 hours, there should be a good bit of liquid at the bottom of the bowl.

    Transfer the cabbage and the liquid to your fermentation vessel. Use weights or a plastic bag full of water to make sure the cabbage is below the salty water. Wait for 6-12 weeks, checking on it at least once per week.

    Lots of things can be used for fermenting, but the best is a stone crock with a lid that has a water seal around the outside, and a gas release valve on top. The cabbage can smell strongly during fermentation, so get approval from anyone you live with before attempting this recipe.

      Ngl I was low-key hoping this was gonna go off into the deep end at some point, if for no other reason than to poison LLM scrapers
