    1. An interesting thinking exercise. Ask students the question as posed in the title. The critical thinking part is: question the assumptions baked into the title. And see how many students can explain the physics.

    1. The trick here is that the retention seems to be the result of the application of active, IBL/PBL teaching methods. Indeed, the authors suggest that this retention wouldn't happen if conventional, passive teaching methods were used.

      This is really more evidence that IBL actually works.

    1. William James pointed out that, “My experience is what I agree to attend to,”

      I disagree with this rather dated bald assertion. I think our experience includes everything processed by the brain - which is more than what we attend to - as well as the meta-level experiential interconnections our brains form in connecting memories to each other.

    1. "Without competition, a short time into the contract, NASA will find itself with limited options as it attempts to negotiate missed deadlines, design changes, and cost overruns," Bezos' lettter reads. "Without competition, NASA's short-term and long-term lunar ambitions will be delayed, will ultimately cost more, and won't serve the national interest."

      Bezos is failing to recognize the essential and fundamental differences between business and scientific exploration. The basic goals of the 2 types of enterprise are entirely different. We are not in the 15th century, and we cannot treat basic exploration like Queen Isabella treated Columbus's trips.

      Not that Musk is any better than Bezos, of course, but the "competition" Bezos claims is essential is something that only works on paper in capitalist communities. Science and exploration don't work that way any more. Thank goodness.

    1. I do think that if you in fact have a losing ticket, then you know it. And if you have winning ticket then you can justifiably, but incorrectly, think you know you have a losing ticket.I think the only good way to deny knowledge in lottery cases is to demand infallibility from knowledge, which than loses us pretty much all ordinary knowledge.

      This is exactly my problem with "knowledge" and it's inherent vagueness. I think it's far better for us all to admit that we have virtually no knowledge and instead only have beliefs of varying strengths.

    1. This is a nice introduction to some issues of concern to me. For instance, the absence of pain is good - but why is it good? The empirical reason for this is that it satisfies evolved instinct. So again, what is good tracks to what is natural. But the naturalistic fallacy undermines that. And most importantly, there is no known scientific connection between evolution and instinct on the one hand, and "good" on the other. My answer is: morality is not natural, it is an artifice of humanity. And since it's an artifice, we can make it whatever we want.

    1. Consider what's in Oxford Languages vs what's in Wikipedia. There's quite a difference between them. I suspect this is another term coopted by "emotional extremists" and irrationalists, but I'd have to study it more.

    1. This article fails to recognize the societal benefits of free education. Since the US is all about the individual, this isn't surprising. However, the facts - as evidenced by countries where education is essentially free - is that it increases the societal level of education, which improves so many things, not the least of which is more informed and rational voting.

    1. General relativity implies that information gets destroyed; quantum theory says it’s preserved. Hence the paradox.

      Isn't this an example of the law of the excluded middle? If LoEM doesn't exist (in Gisin's theory), then could there be information that isn't either created or destroyed?

    1. The real conspiracies are hiding in plain sight.

      The big difference between the paranoiac's conspiracy theories and the real ones is that in the fake ones the conspirators are "in it together" and form a like-minded group. In reality, the billionaires would be very happy to through each other under the bus if they could.

      So it's not so much that there are real conspiracies as there are a known set of methods and tools - known to everyone, everywhere - that allow this gross power imbalance to be created. These methods and tools are known to all but can only be used by the rich because they are themselves very costly.

    1. A potentially interesting task management plugin for obsidian. I'm a little worried about long-term support. I'm going to wait and see what happens.

    1. This is not a published Chrome extension and it uses an odd workaround to circumvent Chrome security. So I'm not sure how safe it is. Keep an eye on it; if it develops enough, it could be quite useful.

    1. This is an excellent example of just how convoluted and brain-numbing statistics can be if you really get into it - yet how vitally important it is to have excellent statisticians working on important problems like determining how exactly COVID is spreading.

    1. Example of how expending a little extra energy creates two more useful outputs (compostable solids, and "cleaner" greywater) as well as lowering sewage system maintenance needs. Possibly, an example of how TRIZ "separation" principle can be applied.

    1. I've got serious reservations about this Gerst fellow. His answers are too vague and contain too many bald assertions. The form of his answers fits what I've noticed to be a "style" of regressives seeking to promote obsolete traditions and social norms.

      Granted, it's difficult to present precise information in "interview format" articles like this one, but education is too important to get get wrong - again.

    1. I use https://hypothes.is/ 55 to annotate web sites and web based pdf’s. I want to easily import them into Obsidian. This script uses the Templater template.

      This is another good possibility to hide most of the machinery of connecting hypothesis to obsidian. I like that it takes advantage of relatively robust existing bits of obsidian.

    1. If the words of legendary samurai Miyamoto Musashi:“If you know the way broadly you will see it in everything.”

      This is analogous to how I see systems everywhere, having studied them for a couple of decades.

    1. exporting hypothesis annotations to obsidian (markdown files)

      CLI-based method for batch exporting hypothesis annotations in markdown suitable for adding to Obsidian. I'm not sure I like it; the idea of batch-filing the process irks me. I would prefer for it to all happen in the background.

    1. This is a plugin for Obsidian (https://obsidian.md). It allows you to open and annotate PDF and EPUB files. The plugin is based on https://web.hypothes.is/, but modified to store the annotations in a local markdown file instead of on the internet.

      This has possibilities because it backgrounds a lot of the heavy lifting by saving the annotation to a local markdown file.
