  • The settlement is right at the border of what would be controlled by the Inca government, two millenniums later. It shows that there’s some decent access to the region from the west than you’d be led to believe, with the Andes in the way.

    As such, if they find other cities further east, I’m predicting that, culturally speaking, they’ll resemble nothing this one; even if they happen to be roughly the same size.

    People ate maize and sweet potato, and probably drank “chicha”, a type of sweet beer.

    “If you don’t have chicha, any small thing will do.” (reference to a certain song)

    Serious now. Potentially yucca too - it grows right next door, and if they got maize from North America then they likely traded for crops.

    That’s surprisingly accurate, as people here are highlighting (it makes geometrical sense when dealing with complex numbers).

    My nephew once asked me this question. The way that I explained it was like this:

    • the friend of my friend is my friend; (+1)*(+1) = (+1)
    • the enemy of my friend is my enemy; (+1)*(-1) = (-1)
    • the friend of my enemy is my enemy; (-1)*(+1) = (-1)
    • the enemy of my enemy is my friend; (-1)*(-1) = (+1)

    It’s a different analogy but it makes intuitive sense, even for kids. And it works nice as mnemonic too.


  • Stating obvious shit like it was some hidden piece of wisdom? Inability to handle subtleties like “lying” vs. “saying an incorrect statement”? Voting system? People repeating the same shit over and over, without reading the others’ comments?

    EDIT: I’m highlighting that this YT comment section shows a lot of things to hate in Reddit. In some aspects they’re behaving exactly like redditors; in some they’re actually doing it better, even if YT is a cesspool of idiocy.











  • Glacial = anhydrous. People call it this way because pure acetic acid has a rather high freezing point (16°C), and it looks a lot like plain ice when frozen. (It still stinks vinegar once you open the bottle though.) But once you add even a bit of water, the freezing point drops considerably, so acetic acid solutions don’t show the same “ice”.

    So in colder days, you need to rewarm it back into a liquid. Then people get really sloppy (I know it not just from that professor’s anecdote, but from watching it). They say “I’m just rewarming it, and it’s just acetic acid, what could go wrong?”. Well, it’s still a big flask of a corrosive, volatile, and flammable substance.

    In the meantime, the same people doing dangerous reactions like nitration (it literally explodes if you let it get too hot - spreading nitric acid, sulphuric acid, and some carcinogenic solvent) “miraculously” pay full attention, obsessively taking care of the temperature of the ice bath.

    Part of the advice that I mentioned in that comment chain is that - smaller dangers are still dangers, do not underestimate them.



  • Most “rules of thumb” become awful advice when used indiscriminately.

    People assign slightly different meanings to the same words. You need to acknowledge this to understand what they say.

    Words also change meaning depending on the context.

    When you still don’t get what someone else said, it’s often more useful to think that you’re lacking a key piece of info than to assume that the other person does.

    Hell is paved with good intentions. This piece of advice is popular, but still not heard enough.

    Related to the above: if someone in your life is consistently rushing towards conclusions, based on little to no information, minimise the impact of that person in your life.

    Have at least one recipe using leftovers of other recipes. It’ll reduce waste.

    Alcohol vinegar is bland, boring, and awful for cooking. But it’s a great cleaning agent.

    Identify what you need to keep vs. throw away. Don’t “default” this indiscriminately, analyse it on a per case basis.

    The world does not revolve around your belly button and nature won’t “magically” change because of your feelings.

    You can cultivate herbs in a backyard. No backyard? Flower pots. No flower pots? Old margarine pot. (Check which herbs grow well where you live.)
