    It takes a bit of work to understand @EricRWeinstein’s ‘take’ on physics. But it’s based on three very clear talents, the first is disambiguation of causal dimensions; and second extraordinary skepticism until he’s achieved that disambituation; and the third is the usual Ashkenazi excellence in explanation by storytelling. And lastly, in opposition, or fourth, he is a better critic than innovator himself – which might sound like a criticism, but it’s more of a recognition of a specialization and a specialization that’s due to his self described “learning disability” (dyslexia?) and frustrations with the university’s inflexibility.

    I had to listen to his speech at Harvard on his theory of what I consider ‘the direction of the solution to the problem’ but not a solution in itself. Then at some point I heard him explain a disambiguation of dimensions. And it was this latter that helped me understand how his mind approaches problems. Tonight, I just heared him use the same method to address a very different problem and recognized his method again.

    It’s not dissimilar from my work on disambituation in to first principles. He’s just doing it with physics and mathematics(cardinality) and I’m doing it with behavior and operationalism(natural order).

    He’s improved quite a bit over the past few years. Although I would prefer that he take on the hard job of proposing actionable solutions. I mean, everyone can compain. Producing actionable solutions is something else entirely.

    In my experiencde, producing a consitution that isn’t ridiculous and is an improvement on our own required a profound effort on my part. And whenever I hear someone talk about our constitution or our law or our political system, I’m tempted to suggest they write a constitution that isn’t even worse.

    It never hapens

    –“Will we ever discover -temp superconductors?”–

    Very hard to know. It, like cold fusion, unlikely. However, the discovery of graphene, despite knowing about carbon fiber for a century, was an example of how we can’t put too much confidence in presumptions of the potential properties of materials.

    Many complex molecules in the physical world, like complex molecules (proteins) in the biological world, can produce emergent properties that we are unaware of. Likewise many complex alloys produce emergent properties. But everything I’ve seen during my lifetime is consistently discouraging. 😉

    However, we are limited by our knowledge of our environment that is the product of our third generation star. While it appears that producing new elements is quite difficult it is not clear that different stars, different planets, with much higher mass and temperature, either during it’s ordinary life cycle, or during it’s collapse will not produce heavier elements with as yet odd properties, such as vastly higher energy storage and dissipation.

    So we can’t be sure. IMO it is very unlikely that we will produce superconductors without temperature or pressure constraints, and that in general light statisfies most if not all of the benefits that we seek from exotic materials. (which is where computing is going if I am correct.)

    THORIUM REACTORS
    The tech is realistic and has widespread support.
    The tech is really, really, expensive to design, develop, and produce.
    Thorium is about three times as abundant as plutonium – but this is misleading, since both are unconcentrated and thorium is a byproduct of the extraction of other rare earth minerals.
    They have figured out how to produce byproducts (waste) that is usable as plutoniam 232. (If I understand correctly) And they claim less waste produced.
    The principle benefit is many small safe durable reactors.
    In other words at present it’s an economic issue, while the scientific tech is probably close to viability, the resource extraction would requre expansion.

    You don’t use PCA for descent. You use it for statistical distribution, the clustering of which turns out to be extremely accurate.

    Jews are the same as palestinians – northern semites, marsh arabs, where arabs are afro asiatics, and afro asiatics appear to have originated in what is Yemen today. And the Ashkenazim are the result of the male diaspora, almost entirely to rome, where they found white wives, and begain rapidly inbreeding again, and forming closed societies, the threat of ostracization from, made a trust network possible – something the europeans only developed with either the state (Rome) or the templars. Having learned writing and finance from the egyptians, and the extraordinary benefits of usury, gambling on credit, sex on credit, alcohol on credit, and baiting farmers into hazard at 300% interest, and continuing the tradition of working with the state against the people, often as tax collectors, and most often rather questionably ethical ones, the europeansresponded by prohibiting ownership so that this baiting into hazard was prohibited of the productive, but the financing of ‘sins’ was permitted, as long as the nobility could use jews for financing trade. So ashkenazim followed whatever naval power was capable of defending shipping, so risk was tolerable.

    I spend an absurd amount of my life debugging pseudoscience. And most of it is non-science, but mere fictionalism, sold to peple who want to hear it.

    Dunno. Just the opposite. In fact, the left dominates every single scientific falsehood and failure of reproducibility. It’s not science that’s liberal, (decadent), it’s the pseudoscience that is.

    Look. I just do the science. And I do the science rigorously.
    So don’t blame me for the truth that we all want to deny.
    If you thought they railed against galileo and darwin, against spencer and nietzche. If you thought they railed against western civilization, with their new ‘narrative’ and ‘social construction’ the uncomfortable truth I’m laying out there is going to be so far worse than those before me.
    But if that’s what it takes to save civilization then that’s what it takes. Because the cost of continuing to ignore the truth is far more dear than any of us should be willing to pay.
