  • Check out figure 2 it shows equivalent cooling in energy units. Meaning how much energy is carried away by perspiration, and showing it for different levels of humidity. I read it as between 5-10% lower at higher humidity.

    Compare that to the radiant heat difference (from 32 degrees to 22, as per the cooling chart) which cools you about 286 % more. And with convective cooling we expect even more at higher temperature differences.

    (Calculated with Boltzmanns law for 310 K body temperature)




  • I don’t know anything about the XR movement, but most movements need different types of activism.

    Protests/demonstrations are important, not the least for visibility and statement, but they rarely lead to change on their own. Most movements need outreach, community, organisation, communication and planned action as well, which can take many forms.

    As each of these parts require their own skill and effort, it might be that any local chapter might have to specialise in one or a few, and you might be better off doing your thing beside theirs’. With some good will and communication, you could probably get support morally and possibly more, and you’ll boost each other in knowing that you’re all fighting for the same cause, although on different battlefields.

    For recruitment, it’s fantastic. A passersby at a protest can much more easily be invited to a book club or bike repair day or vegetarian cooking class, or whatever form you feel might serve the cause. Those events can in turn both be educational in something useful, and further both the movement and individual action.

    Other types of activism also have their places in a cause, find a way to contribute, and consider that you can do more with more people and allies. Getting people to lobby government is cool, putting people in government could also be useful, and the more pervasive collective action, the more change you can enact.


  • You are right that things would still look like we’re accelerating away from us, even if we were actually contracting.

    Interesting hypothesis! How do we investigate?

    What could we expect from a large central gravitational point? We should have other signs of the gravity well:

    We would expect a point that we contract towards (and that seems ill fitting, as we see the expansion moves as the observer (including earth) moves), we would expect some kind of mass or similar effect, which would also have a size to fit it in (we know that gravity works different when you’re inside the mass, and we would be able to see it, much like black holes or dark matter), we would expect things to orbit the gravity well (which we know that at least our galaxy doesn’t orbit us).

    You might want to actually check on these things to make sure they apply and are true, but at least at first glance it seems the expansion is better explained without a central gravity.



  • A common problem (before learning it is impossible/fraught with danger) is categorisation, like sorting of strings.

    Say you have a text, and need to count words of different lengths.

    One intuitive approach is to pass through it once and add each word to a list for the corresponding length, as well as making lists as needed. No 7 letter words, no 7-letter-word-list, even though there are longer words.

    As humans we’re good at sorting things into an unknown number of categories, and we have to unlearn that for programming


  • But the question is not what is simplest for the company. Arguably it would be even simpler for the company not to pay Bob, or anyone for that matter, they could also simplify a lot with not bothering with doing anything beside extracting money from people, slavery and robbery are very simple.

    If we change the viewpoint from people living to serve companies, we might arrive at different conclusions, and maybe even a society better suited for humans, rather than companies.



  • But in several countries it is legally abuse to withhold emotional safety from a dependant, including withholding the right to privacy.

    I know, as I teach this to youth organisations who have a reporting duty against that law.

    As for the health benefits, I’d urge you to read a basic textbook on child developmental psychology. The keywords used in most models are autonomy, privacy and keeping secrets, as important parts of social (and cognitive) development from about the second year, and only get more important with age.





  • If you don’t like the texture, you can let it sit in the liquid for a bit to soften.

    Thicker liquids like (like Turkish or Greek style) yoghurt will take longer, for me about 5 minutes, but I’m guessing you like it mushier. Some have suggested overnight (an unforgivable sin IMHO), but you can easily try it at different intervals to see when is right for you.

    With milk it soaks faster, might be enough for you with 10 minutes.

    The flavors and textures do come from the grains and fruits being only lightly processed though, it might be that you need to transition yourself to it. Feel free to add stuff to get the right texture and flavors, and maybe work backwards from there?
