The “you” was meant as the generic you. I should have said “one” The people who are claiming to fear e.g. all Pakistanis based on the utterance of one, using it to justify their attitude and actions. That’s probably part of the problem; in the US we have politicians describing big cities they don’t live in as hellscapes, describing problems that don’t exist as justification for hating the cities and the people living there. Other people latch on to those descriptions as being true, yet the folks who actually live there are doing just fine.

Part of the issue here is a notion of culture as a static thing, which it most decidedly is not. People have a mental snapshot of it which feeds the illusion, but if culture weren’t fluid parents would have a much easier time of relating to their kids. Music popularity changes, fashion changes, technology changes — all of these things (and more) are part of, or affect, culture. The premise of the OP is that being British is based on being white and that being immutable while ignoring a lot of the rest of the ever-changing culture. Which IMO is racist and myopic. The description of being <Nationality> is not a static thing.

You were inquiring on the topic of relative quantities, and we’ve confirmed that mass is not a relative quantity.

I’ve edited out most of the great void

No. If you transform KE and v between two frames, it only works if the mass is the same.

As studiot points out, some quantities are relative, such as velocity and kinetic energy. Some are not - these are invariant quantities. This can be because of being inherently the same, or because any dependence on relative quantities cancels out, such as with the invariant interval (the variation in the spatial component cancels with the time component) Events can’t happen in one frame but not happen in another. If two objects collide in one frame, they collide in all frames. If you don’t get a fringe shift with a M-M apparatus in one frame, that event will not differ if observed from another.

If the equipment moves, the mirrors are moving away from the source on one pass, but toward the source as it returns to the detector (or the opposite). The perpendicular arm has a different path, too. The train experiment is about the simultaneity of events, and light hitting the mirrors would not be simultaneous for that observer, but nothing happens to the interference pattern

There are a bunch that have just one independent variable. I’m not sure how you argue one is inherently simpler than another

I don’t see how it could happen. Belief is a spectrum and we all have some degree of irrational or illogical behavior. Even countries that actively discourage(d) religious belief have some fraction of the population engaging in it

Yeah, that’s my point about looking at them as entertainers rather than a single subcategory. If you have stage presence you’re a leg up on succeeding in other performance activities. There’s common skills like stage movement and choreography, memorizing lines, and putting different emotions behind your performance. If you’re marginal at those skills you probably don’t do good live singing performances though you might still be successful in the studio. As far as comedy goes, it seems easier to transition from comedy to serious acting than in the other direction.

It was not working for me, in America The last post prior to ~5 hours ago was on Aug 16 (by my computer’s clock/calendar)

It’s racist when you paint all people as the same, based on the actions or traits of an individual. As far as “any other culture” goes, I think that’s just a fabrication. Other cultures are going through similar things and seeing the same kind of reactions, pro and con. You also say “the British” when it’s “some British” which is also stereotyping. It deflects individual responsibility for the racism when you can say everybody is doing it, just like it makes it easier to treat people a certain way if they're all painted with the same brush.

It definitely depends on what you mean by pop icon. If you think of the tent as “entertainers” then singing and acting are just two parts of it, so having successful singers being successful as actors shouldn’t be a surprise, even beyond films merely used as vehicles to promote music (e.g. The Beatles, Elvis, back in the day) But if you also include comedians, Robin Williams did some fine acting in non-comedic roles.

Musicians singing in a musical production shouldn’t be the metric for “film star” since films are about acting, and even if you consider musical numbers as acting, it doesn’t address the range of acting. Cher, Barbra Streisand, Bing Cosby and Frank Sinatra (and more) won academy awards for acting For “film star” you might also consider how many films they made and how big their roles were.

And probably more importantly, GPS. Google maps is a matter of convenience as compared to paper maps, but still requires some navigation skill.

“Rarely” might be headline exaggeration “After adjusting for age, sex, race, ethnicity and education, roughly 1 in 100 taxi and ambulance drivers died of Alzheimer’s, compared with 1 in 60 people overall.” There is mention of a study showing that the brain is changed “under sustained navigational demand” in support of this result The news article https://theconversation.com/taxi-drivers-rarely-die-of-alzheimers-how-complex-mental-maps-and-spatial-reasoning-protect-your-brain-286650 The paper https://www.bmj.com/content/387/bmj-2024-082194

How about you address questions asked of you before asking ones of your own

The number of people needed to run it would be a factor, as well as the firing rate. Also, I imagine boulders to fling are easier to come by than oversize arrows

More trebuchet-related science Shattered skeleton in Scottish castle is first confirmed death from trebuchethttps://www.science.org/content/article/shattered-skeleton-scottish-castle-first-confirmed-death-trebuchet Accounts of the battle don’t mention any trebuchet casualties. But Buckberry says Skeleton 150’s injuries strongly suggest at least one defender was hit from behind by a flying boulder, launched by War Wolf or one of the other siege engines arrayed outside Stirling Castle’s walls. “It’s a huge amount of energy delivered in milliseconds,” Waltenberger says. “In skeletons from past times you rarely see this.”

(since this doesn’t belong in the lounge I’m moving it. I chose ethics for lack of a better idea, though psychology might be a fit) That’s a decent description of MAGA. There are ones not toeing the party line who get cast aside, and the enemy is the dumbocrats. I think the traitor aspect speaks to the fanaticism and initial focus one one or two aspects of the ideology, but as the movement matures you find that not everybody shares the same vision for a wider range of issues. Dissent is probably a distraction and has to be stamped out. As fanaticism, though, it’s emotion and not reason so good faith doesn’t make an appearance

In the US we’ve actively been taking it to an even worse level - cutting aid for countries, making their living conditions even worse, while shutting down immigration.

Yes.
