When they applied Heisenberg principle to vacuum to bring up zero point energy, Casimir force was found, etc., I understood thtis as the principle opposing nothingness.
> you have a compelling reason to go somewhere the time savings of air travel often make it a no-brainer compared to other forms of transport
People who have strong reasons to fly aren't really the main audience for those adverts, then. It's more about advertising cheap fights to Italy for example.
Wanting a holiday in Italy is a compelling reason (for consumers). My point is that it's more rational to fly somewhere than to spend much longer traveling by slower methods. If you want to take a vacation on a different continent, trying to go there and back by ship will consume all your available time.
The existence of air travel is its own incentive; every time someone looks up and sees a plane in the sky, it's a reminder that they could fly somewhere. Flight advertising is just about market share, ie which airline will you choose for the flight you already want to take.
My point is that many people might not consider a flight to Italy unless they see an advertisement telling them it's only 30 euros this week. Without the advertisement they would not travel at all. People who are already in the market for a holiday to Italy are of course not included. It's people on the fence that we're talking about.
The question was only if there was ever regulatory action taken to limit the use of horses the way we are seeing in relation to internal combustion engines.
They recognise that in the quoted paragraph. The JSON-LD thing was only about the open web:
> [MarcXML, BibTex etc] actually have very, very deep support in many places (for example in library and archival systems) but on the open web they are not a goer.
Why base it on ethnicity? I'm not sure the original peoples would have focused on that rather than, say, culture, for the in/out grouping. It's my understanding that the ethnic focus came much later with the rise of nationalism and even later with genetics.
Consider that these seafarers would have habitually mated with people from Britain, Ireland and even the Maghreb as we see here. Do you think they would have considered the offspring of such pairings as less Viking?
For my that culture is essentially gone and it's basically appropriation no matter your DNA.
Are you sure ethnicity was always mentioned as the factor that determine the in/out group? It could be projection, an assumption from your own cultural milieu.
For cultural appropriation, sure. A person born in the USA to a racially Vietnamese family isn't going to get shit for wearing Vietnamese traditional garb despite being raised in America. An American that doesn't pass as Vietnamese sure would.
That ethnicity can sometimes be a factor doesn't mean A) it's always a factor or always the primary factor or B) that we can assume it's how Vikings a 1000 years ago would have thought about it.
Consider also the cases of Americans who, despite being able to show "Irish ethnicity," are laughed at in Ireland for calling themselves Irish. Or people from around the world who take Islam as their religion and are accepted into Mecca despite their disparate ethnic backgrounds. I'd also point to multi-ethnic nations such as the British nation where Cornish, Scottish, Welsh and Saxon are all seen as equally part of the nation.
As I said in my other comment there are a variety of things like religion, cultural practice, common leadership/political belief, geography etc which can and do play roles in creating in/out groups.
I'm not saying ethnicity never plays a role in these things, only that there's little reason to assume that genetics would have been the main playing point in the mind of Vikings.
The whole point of the argument was that changes to routing in the part of the world was contributing to the increases we're seeing. Back the fact that we're seeing increases all over the world suggests that we'd also see increases in Europe/South Asia even without the current conflicts. Therefore it seems like a distraction from the real mystery to focus on it.
