I think it was @joigus who may have pointed out recently that for an understanding of quantum effects one must rely on the mathematics rather than any physical demonstration.(or words to that effect?) Since,in my case it seems unlikely I will at any time soon gain such mathematical understandings could I ask instead maybe for a general description of what those mathematical tools were and how it came about that they were seen to be necessary to address the problem? Was it a gradual process of mathematical progress or were there one or two breakthrough moments ?

So lack of empathy would be a stronger factor than outright hatred(or less strong dislikes)? It has to be dehumanising ?(I think it was common for vanquished peoples to be enslaved but there would surely be some respect for a defeated foe)

Maybe that is how it sounded to you.Certainly not the sentiment I meant it to express. Good people can be lucky as can bad people. People of any kind can benefit from luck. When I think of slavery I think of a very strong kind.The kind where you are hunted down by the "legitimate" forces if you attempt your freedom. Sure there are gradations but I didn't have that in mind.

I am listening to someone singing "We shall not be moved" Very moving and my first inclination is to suppose that the moral and physical strength of that oppressed group was the overriding factor in the changes that brought an end to slavery in Europe and the USA. On reflection I am wondering if I was naive and whether there were other factors that brought about those changes. Can anyone say what they think might have been the main factors? It wasn't a case of economic change that made the practice less profitable,was it? Or the new communication technologies that shone a light on what was happening? It doesn't seem to me that our common wisdom has to increase as time passes and the generations follow each other. Did those African slaves just get lucky at that juncture or was slavery always living on borrowed time?

Would they not have to have been very brave to have openly opposed the war before this? Russia feels like an open prison to me A pit of despair.

thanks(I doubt I will ever get near understanding most of that). Can I ask ,though whether entanglement is an on/off process (for a system of two "objects" or whether it might be possible for there to be any grey area even if below the level of conceivable detectability? , If not ,might it be possible to model entanglement spreading through a system of more than two objects?

Is that why Communism didn't take off in India? Too much of a strain picking up the spaghettified remains from the pavement? https://www.bbc.com/future/article/20220920-how-indias-lattice-buildings-cool-without-air-con

Can all systems be described by one wave function(as I think I may have heard)? Can systems generally also be separated into separate wave functions so that the inseperability you are talking of is really just specific to entangled particles?

Can it be said the the two subsequent objects were one (dynamic) object at the entaglement?

Yes ,a great entertaining lecture from Sean Carrol and most of it very new to me (some of it just providing "internal" context. Amusing how he presents QFT as some kind of an ugly duckling of physics.It is indeed the last part of that general area that I realized I should (could) look at. "All the world's a Field" could be a catchy tune I will have to play it a good few times more now when I get the time

I Thanks,I will take a look at that pinned thread as it does seem very much a propos.

Do the particles exist when their state is undefined? Or do they only exist when there is an interaction? I think this may have been answered earlier but if the state of one entangled particle is measured does it matter when the state of the other is measured? Could it be centuries later so long as there had been no other interactions in the meantime ? Also you mentioned the global fields: Would I be right to think that these global fields arose at the earliest epochs that have been modeled and that they have been "evolving" ever since ,like some kind of physical cosmic organisms ?

Your dance of choice seems to be some interpretation of the Sidestep.I will leave it there and talk to my hand..(think you omitted the "it" :it makes a bit more sense with it)

Are you saying that because the democratic process is flawed and others' views may carry more weight and others less that there is less responsibility to cast one's vote ?(or to by that degree to abrogate one's credibility in consequential political discussions) Politicians, by the nature of their job carry more influence on voting intentions.Should they be disbarred from this function?(campaigning does actually stop in last few hours in some countries at least)

Well,same as here if people don't want to take the vaccine (they could import one if necessary) then they take the consequences. The blame would be taken from the shoulders of the "politicians" and the hospitals would be kept functioning if necessary by according second class status to those who did not "pull their weight" (they can also build new hospitals very quickly ,as we have seen-proper medical facilities I can't say) It is not a big ask to ask the population to take a vaccine if the alternative is one's neighnours foregoing medical treatment for other illnesses. Of course if they don't source the best vaccines for their citizens then they invite criticism from them. Perhaps I am over simplifying....

You are just one person among the millions of others.Why do you feel your vote should have a disproportionate effect? You can't even be sure your vote was well enough informed or well enough intentioned (as an aside) Did the combatants in WW2 or Ukraine just give up because they could not make the final difference personally?

Is that not just a question of getting past the elections and changing policy then?

Strange though that both China and Russia claim,from what I have heard to have become disillusioned with the West(along with many of our own citizens) Do they feel that gives them some sort of moral high ground even though they are sitting in the moral gutter?(I concede that the Chinese CP has lifted its citizens out of poverty and that Russia has ,like every state legitimate security interests) I thought both China and Russia have recent histories of personality cults.They seem to have a tolerance for them.Russia may well be on the way down but I don't see that with China (the future,particularly ours is a very cloudy territory)

Couldn't we all? If anti democratic regimes become the norm then China will be primus inter pares and the democracies may eventually only survive under its suffrance And the US may not remain the bulwark we might wish for if the dice fall the wrong way there (it was a land of hope and aspiration and may fall off its bike when that well is poisoned) How long will Europe et al survive if they are cast adrift?

Some people are more or less considerate twds others and I imagine that they carry that approach into their dealings with the community at large . How do groups of people who have committed crimes of self interest feel about an idea like democracy?(it could be -maybe is, a social study) Criminals are often used in battles against the common enemy as in the Sicilian mafia against the Nazis and now Putin releasing prison inmates and other crazies against Ukraine. Anyway, my idea for democracy is that everyone's existence merits some consideration (if welcomed).We are all members of the club and should not be ignored.

I wouldn't have referred to her as that when she was alive and certainly not now. "The queen"does fine .We don't call TFG "the president " do we unless we want to lick his b...ls.?

You are right . We need balance and the emotional steplock is sickening. I can still hear them on the radio referring to the dead woman as "Her Majesty"

British Republicans will not wish him luck but an end to the monarchy.

Nobody got into bed with them There was always a legitimate hope that Russia could evolve into a half decent political system and ,as with China the hope was that change might come through osmosis. Everyone was taken off guard by this invasion. It may have a silver lining (not for the Ukranians) of both showing their real face and giving the climate change measures due urgency rather than relying on a boiled frog ,(lobster?) response. Easy to criticise Germany but they changed their Ostpolitik policy very quickly -and they are very much in the Russian nationalist's line of fire ("march to Berlin" they were boasting before the invasion)

Still has to be done.If the two party system had its merits it has run out of road and some sort or a more proportional representative system should replace it. Maybe not the top priority and will never happen if Trump returns to power.
