  • It's not actually that intuitive when you don't use kilograms. An American might know what a gram is, but mentally multiplying the conception of one gram by 1000, it's hard to imagine. You really need experience with kilograms to understand kilograms.

    As an analogy, say you don't know Fahrenheit. I can tell you that 32 °F is the freezing point of water, and 100 °F is a really hot day. Is 300 °F the right temperature to cook chicken at? In theory, you can mentally extrapolate, but in reality it's hard to say without direct experience with Fahrenheit in cooking (it's not right, it's too cold).

  • To your last point, I don't value the external appearance of my home at all. I see the outside when I'm exiting and entering. I see the inside for all the time I spent at home. So being able to change the internal appearance is far more important, and condos, as long as you don't compromise the other units, generally give the freedom to do what you want. We need more affordable condos. Renting is still a useful housing supply, but the condo market needs to be absolutely flooded.

    But property is for some reason considered a retirement plan so causing a housing crash would be political suicide.

  • A freefall from space has not been demonstrated. The 40 km jumps done are well below the 100 km Karman line (accepted as the definition of space, but it's mostly an on-paper thing) and much lower than the 400-600 km orbit of the ISS. The thing about these jumps is they begin at ~0 km/h already in or just above where the atmosphere is significant. If you fall from significantly higher than this, you have a lot of altitude in freefall and the atmosphere is so thin that you won't slow down enough for it to matter, leading to a very high speed entry into the lower atmosphere.

    Baumgartner's top speed was Mach 1.25. If you fell from the ISS, your speed when you got to where he began his fall would be around Mach 6-8.

  • If you fell straight down from the height of the orbit of the ISS, by the time you reached the thicker parts of the atmosphere, you would be travelling at around 2 km/s. Unprotected, this is enough energy to raise your temperature by 500 °C, but not all of that energy would actually go into you so you would be a little bit cooler. But suffice it to say, if you have to get off the ISS without a capsule, you're cooked.

  • The intersection point of your orbit would be fixed in space, but because you have added or removed energy from yourself, your orbital period will be slightly different. When you come back around, the station will be a little bit ahead or behind where it was last orbit.

    With each subsequent orbit, this gap would grow until you're on completely opposite sides of the planet at the intersection point, and then it would shrink. Eventually, the difference would come back around to zero and you would hit the station.

    In theory, anyway. In reality, perturbations in your and the ISS' orbits would almost ensure you never hit it again for a very long time, if ever.

  • To half the users in this thread, normal people use computers as a means to an end.

    "If you're not prepared to get your hands dirty this OS is not for you" you've already lost me, this is unhinged behaviour. You have one life and you choose to spend it fixing your computer so it will do the same things except slightly differently.

    But I know this is an unpopular opinion for Linux users.

  • My school gave us swimming lessons but they were not very accommodating to me, I came out of them not knowing how to swim. When I lived with my brother, I taught myself to more or less be able to swim in his pool. It's just very tiring.

  • The whole thing about flat earthers is that they come up with more and more elaborate explanations to fit each individual observation, when Occam's razor says that the theory that explains them all should probably be the correct one.

    Like, they'll argue about refraction of light due to hot air being the cause for the disappearance of ships past the horizon, and then their explanation for how time zones work is something else entirely, and why we have seasons, and why planes take the routes they do, and all this other nonsense. They all need separate, complicated explanations, and they willingly accept them and vehemently deny the simplest theory that ties everything together.

    The actual explanation for this behaviour is flat earthers are a friend group, doubly so for the people who pushed "globeheads" out of their life. So to change their view is to socially isolate themselves

  • The thing about it is aluminum cans leach into their contents, especially if left open. Aluminum isn't particularly harmful in that amount but it's something you can taste, particularly with acidic contents. Not sure how much water suffers from this, but if it comes through in things with flavour, I'm sure it would come through in water, which is supposed to be flavourless, even if it's not usually very acidic.
