  • You can’t say bad things about the government in China.

    This might sound like an absurd restriction of free speech, but consider that it’s also considered highly illegal in germany to ask for the abolishment of democracy. Many far-right groups do this, and the Verfassungsschutz (basically a kind of special police force) keeps a close eye on them because of that, calls them “verfassungsgefährdend” (going against the constitution). Monarchies like england had similar laws around 1900, where you could say everything except talk badly about the monarchy in power. That was known as the “english liberalism” because in many other countries, you could say even less. China does the same today, just that instead of the german constitution or the english monarchy it’s the Communist Party.











  • fun fact: chloroplasts generate an electric potential across the cell membrane during photosynthesis. essentially, they have membrane proteins in their chloroplast membranes that push electrons from one side of the membrane to the other side whenever a photon hits the protein. It’s essentially a natural photovoltaic cell.

    That electric potential is then used to create ATP in nature, while we just directly extract the electrical power through cables.





  • There’s only 3 major ways to transform different forms of energy into electricity, which are:

    • solar panels (light -> electricity)
    • mechanical engines/generators (mechanical movement -> electricity)
    • electrochemical battery (chemical dipole -> electricity)

    there’s a whole lot more, such as thermoelectric generator and piezoelectricity but these are the three significant ones.

    note that i distinguish these categories by their core essence, such as whether they’re using changes in magnetic flux (like a mechanical generator) or transferring 1 photon on each electron (like solar panels), instead of looking at what source type of energy they transform.

    because there’s many ways to transform e.g. light energy into electricity. you could also heat water with the sunlight and then drive a steam engine with it. but that’s not what i care about. i care about the fundamental connection between different types of energy, and how they can be directly transformed to one another.



  • That New York Post article is a hate-filled piece of garbage.

    For example, it hates against these “polarizing rat-riddled street dining shacks” (quote is from the article).

    I can guarantee you, i live in Vienna, we have these things all over the place. There’s at least 5 of them on my way from where i live to university. There’s never been any problems with them. In fact, they’re delicious and typically much cheaper than sit-in restaurants. That’s probably because they don’t have to pay for expensive rooms. That makes the food much cheaper, it’s typically around 5€ for a kebab (basically a sandwich) compared to 12€ for anything you get at a sit-in restaurant. I have gone to these street dining shacks every day for years and never had problems.
