  • But temperature is not just the speed of a molecule right?

    It pretty much is.

    Like a molecule moving very fast through space can still be at a very low temperature, right?

    That very much depends on the relative speed of the molecule and you. If you’re not moving in relation to the molecule, a collision between you and it won’t do much. Now try being hit by it (or a bunch of them) at high or even relativistic speeds. The area of you that’s hit will surely become pretty hot then.

    Like, have you seen footage of asteroid impacts? Have you seen shooting stars? Those are hot. Like, non-figuratively.







  • The system, no matter how good its education, will never be able to turn everybody into “decent philosophers”. Some people just aren’t smart, no matter how good education might get. Some just are gullible. That doesn’t mean that they shouldn’t be as well-educated as they can possibly be, but people and their capabilities just are a spectrum and always will be. And even if today’s dumbest people will be as smart as today’s “decent philosophers” by tomorrow, today’s “decent philosophers” will still outsmart them, which is an issue if there are manipulative people with hidden agendas among them. Which they will be.

    This isn’t an education issue, it’s an information and misinformation issue. Giving anybody, including malicious actors, their own, personal channel to spread whatever information they want, regardless of its quality or truth, has turned out to be a terrible idea. The Internet kind of comes with the idea to give everyone access to all of humanity’s information without taking into account that there should be a certain responsibility attached to the question of the creation of that information or that there should be a separation of concerns between people who spread information and people who have other interests than just informing people in the best way possible.









  • Just looked it up because I was wondering as well.

    First, the image says “aqueduct bridge” for the first arched bridge, not “aqueduct”, because the whole thing you see there is the aqueduct.

    Second, while Romans also simply built walls if they didn’t need as much elevation (and because they’re easier to build than those arches), as soon as you have successive arches, you have an arcade. So in the image, they’re both arcades and it’s just labeled weirdly.
