  • By the standards of whatever Siberian village, the compensation and various bonuses (including after they die) these guys pull is insane. That how they’re convincing people to sign up for a war that’s both unpopular and nearly guaranteed to kill you. They could try massive conscription, but they’d need loyal people to enforce it or a guarantee it wouldn’t lead to regime change, and they have neither.

    The Russian government is basically drawing down all the funds and infrastructure in the country to sponsor this war, and at some point here they’ll run out. I think I have 11 months left on my prediction of by when.











  • Tribalism is ancient for sure. As is cultural bigotry. Hating people primarily do to skin colour and related features is a thing that specifically developed 1500-1700, as the trans-Atlantic slave trade got going (and needed to be rationalised).

    When the Romans or Mesopotamians hated on their neighbors, it was over food preferences, language and customs. If they ascribed anything biological to it, the prevailing theory was more about response to the local climate than heredity. Then, once monotheism got going deviation from religious orthodoxy became the most popular way to hate. It’s not a coincidence that “Slav” and “slave” sound similar, because pagan Slavic people were a major source of slave labour in medieval Europe. It drove the crusades, and it had a role in the early stages of expansion into the new world.

    The first slave ship came to English North America in 1619, but the passengers were treated as normal indentures, and at least some became free later on. They kept coming, though, and by 1700 or so black people had to be slaves and that was pretty much it. (Colonial Spain had their own, somewhat divergent system a bit earlier)

    The Romans had emperors drawn from Africa and the Middle East, and had conflict with Germanic and Celtic people that could easily have been Latin by appearance. The first sub-Saharan African in Japan was made a Samurai, and now there’s a videogame about it. That’s not to say the difference in appearance wasn’t noticed or remarked upon (they tried to wash the dark off of Yasuke, and Heterodotus makes special note of the woolly hair and stature of the distant Africans) but in every pre-modern story I can think of it was gotten over quickly compared to other, behavioral things.

    Anyway, I guess the point is just that there’s been steps backwards as well. There would have to be, otherwise ignorance would have gone extinct over the millennia, right? Maybe it still will; we live in a totally transformed world now, but it’s going to require continuous effort. Hate is always shifting and changing and evolving from things that might even have started off as harmless or positive (Jesus is less controversial than later Christians).



  • I’ll admit, I only have a fuzzy understanding of even the basics of Hamiltonian mechanics. I understand quantum computing, though, and that evolution of a circuit is a unitary (linear) operator/matrix. So, wouldn’t continuous evolution be a one-parameter Lie subgroup of the unitary operators over your Hilbert space? Any eigenvalue would have to be a root of unity, with the exact one corresponding to rate of change in phase, because otherwise you end up with probabilities not summing to 1.

    I think it would be analogous to the normal modes for a classical standing wave, which are also used as examples of an eigenfunction.

    Maybe the more relevant question is if nonequilibrium, dynamical quantum systems can also be said to be quantised in the same way. Can they?

    If the problem is easier to think about with a time-dependent Hamiltonian, you can use the Heisenberg formulation of quantum mechanics, which makes the wavefunctions static and lets the operators evolve in time. This can be helpful in a number of situations—typically involving light.

    That sounds wild!


  • Community, status and not being economically punished are way bigger motivators than being abstractly correct, right? Nobody really goes looking for inconvenient truths. Unless those naturally nice, understanding conservatives start meeting a lot of very different people, like if they move, the worldview will probably stay put.

    To be a little more doomer than you, I’d actually say there’s lots of people that go the other way as well, and go looking for a cult to join as an outlet for whatever nastiness is inside of them. Consider that in the grand scheme of things, monotheism and racism are both new.
