  • yeah this is not as surprising as it looks like

    between pure fission design and thermonuke for a militarily relevant yields, say, 100-500 kt range, both designs are in principle working, but thermonuke is both compact and derives most of energy from cheap materials (natural to moderately enriched uranium and lithium deuteride). This is important if you remember that this thing has to fit in an ICBM

    thermonukes have an extra advantage that they’re staged, that means dial-a-yield becomes possible - not all parts have to be used



  • it’s a spicy autocomplete. it doesn’t know anything, does not understand anything, it does not reason, and it won’t stop until your boss thinks it’s good enough at your job for “restructuring” (it’s not). any illusion of knowledge comes from the fact that its source material mostly is factual. when you’re drifting off into niche topics or something that was missing out of training data entirely, spicy autocomplete does what it does best, it makes shit up. some people call this hallucination, but it’s closer to making shit up confidently while not knowing any better. humans do that too, but at least they know when they do that


  • planck length doesn’t come up even once, it all boils down to these things: 1. electron has momentum, and from that follows it has a wavelength, and at the same time 2. orbit is stable, which means that after every “rotation” electron has to end up with the same phase, which means there is only a finite number of solutions to time-independent schroedinger equation for (hydrogen) atom (don’t bother solving it on paper for anything with more than one electron) and these things are spherical harmonics

    planetary orbits are not quantized, for starters. atomic orbitals are occupied by pairs (at most) of electrons, and this is because of qm spin exists which has no analogue in large scale. electrons aren’t spinning around on an orbit, they’re more of a smudged standing wave. it’s also a staple among vapid thonkers like mckenna
