    This also explains why evaporation cools down (like when you sweat): the molecules with the highest temperature are the ones evaporating, so the average temperature decreases as those high-temperature molecules leave the system. Only the relatively colder molecules are left behind - thus it cools as a whole.

    The main principle at work here is the enthalpy of vaporization. When matter changes state, there is an associated amount of energy that is absorbed or released - in the case of vaporization, energy must be absorbed. So when sweat forms on your skin and evaporates, it absorbs heat energy from your body in order to undergo that state change.

    For water, the energy involved here is remarkably high, much higher than the energy stored by a few degrees difference in temperature. For example, if you wanted to boil off 1kg of water, it would take about 300 kJ to bring the temperature up to boiling from room temperature and over 2000 kJ to boil it all into steam.

    @Gaywallet I have a couple thoughts on this:

    1. This seems like a way that device attestation could worm its way further into our devices. Right now Google is trying to watermark AI-generated photos as AI, but you could easily go the other way - if a photo hasn’t been manipulated, it’s signed with a key that is locked down to device attestation. What, your phone is rooted? That’s kinda suspicious - how am I supposed to know your photos are real?

    2. Short of that, though, I suspect that the most likely consequence of this is the videos will start being increasingly seen as necessary for true proof, since those are harder to fake - for now, at least. And of course, there will be a lot more misinformation on the internet, especially in the short term while awareness of this catches up.

    “Why didn’t she just keep her job, give us part of the wages to pay somebody else to do it?” he asked. “That is the thing that the hyper-liberalized economics wants you to do. The economic logic of always prioritizing paid wage labor over other forms of contributing to a society is to me … a consequence of a sort of fundamental liberalism that is ultimately gonna unwind and collapse upon itself.”

    “It’s the abandonment of a sort of Aristotelian virtue politics for a hyper-market-oriented way of thinking about what’s good and what’s desirable,” he added. “If people are paying for it and it contributes to GDP and it makes the economic consumption numbers rise, then it’s good, and if it doesn’t, it’s bad … that’s sort of the root of our political problem.”

    It’s really funny when conservatives are like “See the problem with Wokeness is <describes capitalism>”
