    The reason you experience the chills when you spike a fever is the brain sets the desired temperature higher and as a result you perceive cold at your current body temperature. And also why you feel like you are in a sauna when your fever breaks, because the inverse is true.

    To be clear this set point does mean induction of peripheral actions to actually elevate the temperature, but the central component of this symphony is the hypothalamus.

    There is a lot of uncertainty around fever signaling, here is a great summary of what we know.

    I legitimately want to understand how this information is propagating and why. Your explanation seems correct, but given the above link, there may be more to this problem. Honestly, I am just confused now.

    Its the previous thing of it, potentially, being true somewhere and then also just it sounds like it could be true. TikTok is full of stuff like this, that sounds true enough and is presented from somewhat of an authority angle, with confidence. Too often I get someone to send me a tiktok of some medical fact like: “is this true?”. And 9/10 it is not.


  • Its worth mentioning that certain mainstream interpretations are also concretely deterministic. For example many worlds is actually a deterministic interpretation, the multiverse is deterministic, your particular branch simply appears probabilistic. Much more deterministic is Bohmian mechanics. Copenhagen interpretation, however, maintains randomness.


  • Its not that odd if you think about it. Everything else in this universe is deterministic. Well, quantum mechanics, as we observe it, is probabilistic, but still governed by rules and calculable, thus predictable (I also believe it is, in some sense, deterministic). For there to be free will, we need some form of “special sauce”, yet to be uncovered, that would grant us the freedom and agency to act outside of these laws.


  • Seth Anil has interesting lectures on consciousness, specifically on the predictive processing theory. Under this view the brain essentially simulates reality as a sort of prediction, this simulated model is what we, subjectively, then perceive as consciousness.

    “Every good regulator of a system must be a model of that system“. In other words consciousness might exist because to regulate our bodies and execute different actions we must have an internal model of ourselves as well as ourselves in the world.

    As for determinism - the idea of libertarian free will is not really seriously entertained by philosophy these days. The main question is if there is any inkling of free will to cling to (compatibilism), but, generally, it is more likely than not that our consciousness is deterministic.


  • Physics and more to the point, QM, appears probabilistic but wether or not it is deterministic is still up for debate. Until such a time that we develop a full understanding of QM we can not say for sure. Personally I am inclined to think we will find deterministic explanations in QM, it feels like nonsense to say that things could have happened differently. Things happen the way they happen and if you would rewind time before an event, it should resolve the same way.

    1. Our childrens hospital (besides the ICU that uses a phillips solution on windows, which integrates with the monitoring and anesthesia equipment) runs linux, however they do this in a virtual environment on windows, the reasoning I am not sure about, potentially to sandbox the electronic system they are using.

    2. Its almost exclusively to do with the software they need, it often wont run on linux or will have limited support.
