Just allowing it. Previously, Ukraine was one of the countries that required citizens to surrender all other citizenships, or at least didn't recognise them.

Kind of annoying they don't say in the article.

So is that a plane at the beginning?

Has any place in the world ever been actively “flooded” with migrants of a vastly different culture in recent history?

Any place that borders a very culturally different country that has a massive crisis. They usually get banned from working and shoved in refugee camps, though.

But anyway,

Why are humans like this?

Probably stuff that happened in prehistory, some quirk of evolution. It's definitely not rational.

He didn't drop dead immediately either. Poor guy, should have stayed home.

The really successful religions and eventually empires just happened to be homophobic, so anyone conservative globally is likely to be homophobic.

It's actually a pretty LGBT friendly region anyway, it's legal in most of Indonesia, even, but they border Malaysia where gay stuff gets hard prison time.

Edit: As in, SE Asia is a relatively gay-friendly region, for whatever reason. It's not because social conservatism is out of style.

Indonesia itself is meh. Better than Malaysia, worse than Thailand. And the Muslim part will cane you for it, per the article.

Arabia hasn't been closely involved for a long time. Actually, I don't know if it ever was or the someone like the Mughals were an intermediary, off the top of my head. It's far away from the Middle East.

Religious conservatives gonna religious conservative. If you go back to ancient history sometimes they were fine with homosexuality, or even expected some amount, but that died out along the way. Because of the European empires, but only because they were more successful, so I wouldn't blame Europe either.

Maybe it's like the smoky tomatoes you can buy in cans?

I mean, that is what you'd expect if were hormone-based.

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).

What do you mean? Almost everyone wants more, and will gladly take it if they have an opportunity. That's why lotteries exist, right?

Big history is full of open questions, but there's counterexamples. Short-lived republics are a dime a dozen, while Egypt lasted for thousands of years. There are known cases where inequality actually increases with the end of an empire, like how Roman Britain with it's public bathhouses directly gives way to dark ages Britain with feudal lords and manors. In some cases, a disenfranchised group getting a bit of power is destabilising.

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!

Ah yes, pretending intransigence isn't happening to stop different intransigence. Definitely a sustainable strategy, and definitely not part of why Hamas doesn't trust US negotiators in the first place. /s

The short term plans have been shit like this. The long term "plan" has been slogans and platitudes. Repeat for decades and unsurprisingly it escalates to genocide. This has been the shame of the West in my lifetime.
