  • A couple notes:

    First, renormalizarion was hand-wavy when it was first introduced, but it has since been made mathematically rigorous. Additionally, renormalization is a mathematical process to make a theory self-consistent. If you consider it an odd idea because it is physically nonsense, I would caution against forming a physical intuition from any given accurate mathematical model. Especially with fundamental quantum mechanics—there’s a reason why there are several interpretations of QM and have been for a century.

    Second, and arguably more importantly: this ScienceDaily article is extremely misleading. The original paper (linked by OP in another comment) says

    This is a scenario where the inflaton does not exist, and thus opens up the possibility to provide a picture of inflation that is model independent

    So the paper does rid itself of the inflaton field, which is, as you said, a bit of a hand-wave. Crucially, however, it does not abandon inflation—in fact, it explains those “for no reason”s that you mentioned.






  • a) it’s quite common, so a lot of people have encountered it

    b) feet are rather dirty, so it evokes disgust in those that don’t have it

    This creates an environment in which people can commiserate in their disgust with others by means of insult. This creates a meme that people will take on as a belief to join the in-group / avoid being targeted by the majority.

    It’s the same as a lot of arbitrary hate, honestly.




  • It’s basically a philosophy paper—epistemology, to be specific.

    Frequentism and Bayesianism are philosophies of understanding probability and statistics, and this paper argues that Bayesianism provides a more clear understanding of truth.

    To summarize their main points: P-values and confidence intervals and their ilk are confusing to the uninitiated and initiated alike, so their use should be discouraged. Undergraduates shouldn’t even be taught them since they confuse most people, causing public harm. All frequentist statistics at this level should be purged from education and replaced with Bayesian statistics.


  • Disclaimer: I have no experience with this drug class, and my medical knowledge is that of a novice.

    “Don’t expose it to light” typically means “don’t leave it in the sun too long.”

    These warnings usually mean that the chemical will denature / break down when exposed to light or heat which leads to a decrease in efficacy. Most chemicals will only do this in response to IR or UV light. If the reaction is from IR, then the primary worry is keeping it cool enough. By the nature of indoor lights, your bathroom light is almost certainly not emitting enough UV to cause a reaction.

    If the drug is colored (I don’t believe this to be the case here), then visible light could cause a reaction, though I would still find it unlikely that a drug would lose sufficient efficacy due to a bathroom light.

    I wouldn’t worry unless it got too warm for too long.

    I can’t say anything about the label turning red without a bit more info about the container itself (is it just a vial?), but it sounds like it might be an indicator that you took your last dose.

    As always, contact your doctor or provider if you have concerns.
