  • The efficacy of vaccines usually declines over time after administration. The immune system starts to “forget” how to fight a pathogen it doesn’t encounter. It doesn’t completely forget, but it puts the treatment data way back in the archives. So when it encounters the real deal, it can take quite a while to boot up production of antibodies. It also varies by the type of disease.

    This is fine for some slow diseases ( which is why sometimes a single vaccination can suffice ), but can be risky if the disease progresses faster than the immune system can ramp up the defenses.

    Administering the vaccine as soon as possible after suspected exposure to deadly or highly contagious diseases simply helps the immune system to get the necessary blueprints to get in the fight quicker.

    Administering the vaccine before any exposure at regular, long intervals is done to decrease the baseline risk. Sometimes you don’t know you have been infected. Many diseases are not only transmitted by dramatic, obvious vectors. In those cases, it’s definitely better to have some old defense than none at all.


  • If my post came across as a comparison, it was not meant to. Of course the average scale and intensity would be higher in occupied territories.

    I just wanted to highlight that a vast majority of Germans have both the knowledge of the terror their ancestors committed due to the schools’ focus on keeping every new generation well educated on it, while combining it with the traumas their own family or communities experienced.

    This combines into a fairly strong anti fascist society.

    Yes, we have neo nazis and all other flavors of right wing extremists, but they have much less real power than some international media reporting might make you think. Exactly because the majority of society is sensitive to this and does rise against it in numbers.

    Even before the current wave, there never was a right wing demonstration or rally that wasn’t accompanied by a liberal counter rally with at least a hundred times their number. And even then those weren’t left wing extremists or other political radicals in the majority. Most of these types of rallies have a large number of very boring participants, people that are close to apolitical otherwise.

    Regarding AfD: remember it’s not an openly fascist party, unlike the previously existing NPD, which is now forbidden. AfD claims to be a neo conservative party, a bit further right than the big CDU ( which is center-right). And the AfD keeps dancing on this line, in some areas actively pushing out people as soon as their fascist activities become known and turning themselves, while simultaneously following a slightly tamer route. It’s a dangerous and effective way of moving the goal posts of public discourse, especially with no other party effectively engaging their topics. The AfD group revraled to participate in the current nasty discussions is not even a hundred people. I’m confident you’ll find a couple dozen idiots of their scale in every larger city of this world.

    But every time they slip up like this in Germany, they experience massive setbacks.

    It’s still important to recognize their danger and work against them, but Germany is far from lost to their twisted ideology. But media does like to be sensationalistic, even when it has good intentions.

    A US comparison might be how the tea party developed as an offspring of the Republicans, and how they subsequently shifted the entire political landscape, despite them actually only bring a rather small group. So many unthinkable policies that nobody would have even considered worth a discussion are now on the table for actual legislative processes.



  • I’m keeping your soda bottle analogy:

    In this case, a very strong eruption ejects kids of super hot gas and rock upwards, like when you open a shaken bottle. After some time, pressure will decrease, and gravity will start dragging things down again.

    Unlike a regular soda bottle, heat is significant. Hot gas rises in the atmosphere against gravity. During this rise, it loses energy ( so it cools down). When it reaches a high enough temperature where the lifting momentum is overcome by gravity, it starts falling again.

    As the top starts to fall while there still is more material below in the column, the column gets compressed. As the center of the column is the hottest part, it still pushes material upwards. So the colder material falling from the top is pushed outwards, widening the column a bit. It also encounters the cold air outside and starts cooling even more itself, falling ever faster in the outside “ring” of the column. It still is only “cool” compared to the rising inner column, still thousands of degrees. Also, all the light glasses will have moved further up the atmosphere and either fall slower or not at all. This is where the long term effects such as your mentioned ash fall/ rain comes from. So most of the rapidly falling material that then form pyroclastic flows are actually fairly heavy liquids/solids and heavier-than-air gasses. They only seem so light and fast inside a pyroclastic flow because if their immense temperature and contained energy.

    However, sooner or later the falling material encounters the ground, a solid obstacle. As the inner column is densely filled with super hot, probably still rising fresh material, the only possible way is outwards. And with continuous pressure from above from all the falling material, the material needs to move out of the way very rapidly. This is not dissimilar from how water behaves that flows from a bottle or faucet and hits solid ground. But a pyroclastic flow is a bit more viscous, and still very hot. While moving outwards, it quickly has to push away the cool, resting atmosphere. The only way for the air is to step aside upwards. Now, as the cold air likes to stay close to the ground and was compressed, it forms a seemingly paradoxical barrier layer of cold, dense air above the pyroclastic flow, pressing down on it, even squeezing it further outwards. This together with it’s own viscosity means there’s surprisingly little turbulence between the two layers, with the hot flow continuing to rush along below the cold barrier layer instead of mixing and rising through it upwards. If this interests you, look up inversion layers: they are a normal phenomenon in regular weather as well, especially winter time, and can sometimes even last many days.

    Consider that ash columns reach many km in altitude, filled with many tons of material. It doesn’t all fall slowly at the same time. It’s literally rock falling from high atmosphere to the ground, carried by heavier-than-air gasses that also want to sit below the atmosphere.




  • And getting rid of the unfair preferential terms is good for the EU as a whole, because it will reduce resentment in all other current and potential future member nations.

    Don’t get me wrong, I absolutely believe Brexit hurt everyone in Europe and I can’t wait to welcome UK back into the Union, but make it on equal terms. It’s a very small silver lining to the whole fiasco. I just hope it doesn’t take too long for UK to find a leader string enough to say “I think we made a mistake, we should reapply”. Make a new referendum while the populace still realizes the connection between Brexit and the current misery before some populist schmuck finds a new scapegoat.


  • I do. I do not understand why this tiny delivery bears mentioning compared to all the other, much larger deliveries.

    And I want to highlight how little all the billions of aid will mean if the West now just stops delivering, simply because the public is bored of the war. War is expensive, but sometimes there’s no alternative. And cynical at it may be, supporting a proxy to fight for you on their ground is still hell of a lot cheaper than your own people dying on your soil.



  • This doesn’t change the issue presented by OP. Sea level is not level across the world. In fact there are much larger differences than most people expect. The Earth is not perfectly round. Earth rotation causes the equator to be affected by a centrifugal force, making it wider there ( more distance to earth core means less gravity ) than at the poles. Overall, gravity at Earth surface level varies by 0.7%, ranging from 9.76 in Peru to 9.83 in the Arctic Ocean, but it’s absolutely not linear. In addition, the Earth is full of gravity anomalies. These cause localized dips and spikes in gravity. Two of the big dogs lips lie in the Indian ocean and the Caribbean. Because water is fluid, sea level is very much affected by local gravity (as well as other factors such as air pressure, salinity, temperature…). Which is also why the moons gravity can cause tides. The permanently lower gravity on these anomalous spots mean that the average sea level here is lower than it would be on a perfect sphere. This difference can be up to two meters in sea level.

  • Almost all western leaders have condemned Israel blocking vital supplies and the forced indiscriminate expulsion of civilians from north Gaza, as far as I know. Just like they condemn the atrocities of indiscriminate murder and kidnapping of civilians committed by Hamas. International aid is still being sent to Palestine, except where Israel blocks it. And the international community rightfully complains that this blockade is not in accordance with humanitarian laws and applies diplomatic pressure to get it through.

    “The West” is neither accepting Israels logic blindly, nor does it excuse Hamas transgressions. But it mostly does it with words for fear of escalation. This also applies to nearby Arabian countries, by the way. Egypt refuses to accept Palestinian refugees for fear of Hamas establishing a base in Egypt Sinai and firing rockets from there, which would risk a much larger conflict. Nobody except Hamas, Hisbollah and Iran - and Russia, because it distracts from Ukraine - wants the conflict to escalate.


  • It’s interesting how different the quality of schooltime can be, and how perception of said time can differ for school kids as well. I was in a “full day” school starting from age 9 in a country where regular schools end at lunch time. Our school had the same curriculum to go through as every other, but lots more time to do it. The extra time was filled with dedicated self-learn time ( basically to do homework, but you have your classmates around to talk and help each other and can reach out to teachers if you really struggle with something) and elective extracurricular activities. It was mandatory, but you had free choice between all the offers. Teachers had to offer something, and usually offered their personal passion activities/hobbies. This led to these activities being the highlight of every kid’s week, because there was enough variety to choose from to find something you liked. Kinda like club activities in US schools, but much less codified and without competitive objectives. Some examples are photography, pottery, soap box car building, school beautification ( we literally were allowed and encouraged to graffiti/mural the school walls :D ), gardening, natural science ( basically constantly doing fun physics and chemistry experiments without boring theory), electronics etc. . This was intentionally kept separate from sports or music, which also were partially elective: you had to do sports and music, and some basics were mandatory for all, but you could opt for specializations. All this semi-forced mingling served well to prevent the formation of strong clique boundaries, without inhibiting kids from pursuing their talents and passions.

    All that had huge advantages. Kids from troubled families had a much easier time of keeping up with everyone else, as help from home was hardly necessary. Lunch was provided by the school. Wasn’t stellar, wasn’t horrible. But it was available to all students for free, and that can be very important to some as well. It took me a long time, often only after visiting school friends for the first time or even after schooltime was over entirely, to realize how crazy rich or poor some of my friends’ families actually were, or what difficulties they sometimes faced at home and that there was a reason we never were invited to visit them. At school, it simply didn’t matter to us. Sure, some wore more brand clothes than others, but nobody thought of using this as a measure of personal quality. Class cohesion also was usually strong. Sure, kids still were assholes and bullies like everywhere else, but it usually got solved internally quickly, because it was harder to keep it up for full days with plenty of “forced” social time, and you ended up being more confronted with the damage and hurt you caused. And in really bad cases the proximity to school made it much easier for teachers to pick up on any developments in their students and classes and react quickly. There also were some mandatory “social skill” classes to teach everyone basic conflict solving and mediating. It was only one or two sessions per year, but I think it actually helped, even if we kids usually scoffed at it at the time. It was very clear the school philosophy was not to push through a curriculum, but to use the extra time to help explore and form personalities that later will hopefully enmesh well in society. And yes, our school had a bit more teaching personnel than other schools to fill all the time slots and extra activities, but we still had 25-35 students per class, it was not some utopian dream.

    We kids loved the full day spent at school as well. No homework, and what’s better than spending the entire day with your friends? The school was far from my home, so I left the house at 6:30 and usually got back around 18:00, with about 40min of train commute plus 30min of walking (one way). Only Friday ended at lunch. Still never felt that I was lacking “me” time.

    Tl;Dr : It matters a lot how the time at school is used.
