Just looking for other's opinions here... Are the 'violent' protests feeding the neurosis of the current occupant of the White House ? Or would non-violent protests simply be disregarded, and 'business as usual' shortly ?

When I mentioned that people are painting Moreano as a racist, Zap mentioned he already has two coats. ( there's that hidden meaning to words and phrases, on both our parts ) Exactly ! Whether Moreno is ignorant, or willfully ignorant, is a byproduct of education and/or life experience. If you can't see that it has nothing to do with the fact that he hasn't lived in the US for more than 6 months, and you choose to blame his attitudes on that fact, when you also haven't lived in the US for any extended time, you have the problem, Dim. Not me. And if you don't like my contributions, why do you always engage with me ? I look forward to our next disagreement .

OK. I guess we can go with "ignorant" then. Here is the 'strawman' INow.. I don't particularly like it when 'labelling' takes the place of reasoning. Calling people racists, or ignorant ( especially when the criteria used also applies to the user ) is counterproductive to the discussion America ( and some other parts of the world ) needs to have in the wake of this eye-opening incident. The time for pointing fingers and divisiveness is way past, only by working together can we bring about change and move forward. One simply needs to ask Moreno "How do you feel when you watch the video death murder of G Floyd ? Do you think that this is OK ? What about all the other shit that black people have to put up with every day of their lives ? And do you think it's time for a change ?" You might find that he thinks a lot like the rest of us.

Can we please get back to the G Floyd incident and any potential change, instead of everyone trying to score points by painting Moreno as a racist ? I find it funny that a bunch of Brits have labelled him ignorant because he has never lived in the US for more than 6 months. How long have Dimreepr and Strange lived in the US ?? Surely you can make a better argument than that ! Seems former slave, Mr S McGee, lived to a ripe old age of 130... "Died: October 15, 1971, Columbia, Mississippi Born: May 29, 1841, North Carolina" Slavery must be good for you ! ( Or the dates are wrong )

I do 'get' it, Dim, Zap, CY, INow, and all who have tried explaining. My concern is that often we find 'hidden' meaning in certain words or phrases. Usually because our perception of those words or phrases are colored by our life experiences. And not to make light of a person losing his life to deliberate brutality, but this incident couldn't have come at a worse time. In about a week there will be an explosion of Covid-19 cases all across the US. And of course, predominantly in the communities that took part in the protests. How many more will die ?

Sorry CY, bad choice of ethnicity; just pick any other disenfranchised and oppressed group of people. It doesn't change the point I was trying to make ( and now, I'm not sure if it got across ) I have edited my post from Oriental to another group of oppressed people. Just to be clear, 3rd degree is the more serious offence to manslaughter, right ? so whereas before they could expect 3rd to be plead down to manslaughter, now they expect 2nd to be plead down to 3rd ? ( I wasn't even aware there was a 3rd, previously ) In that case what are the 'levels' of premeditation that separate 1st and 2nd degree murder ?

I understand your points, INow and Zap, and fully agree with it. But say you have a protester with a sign that said "Native American lives matter also", would he/she be kicked out of the protest march ? What if another was carrying a sign that said "Latinx lives matter also", do you think they should be kicked out, or admonished for it ? Or protesters with signs that say "Oriental Muslim lives matter too", would they be fired from their jobs, or receive neg reps on this forum ? Because that is what is happening when people try to be inclusive ( remember when that was a politically correct word ) and say " ALL lives have to matter if we are to get past this mess ).

But when is he going to improve the situation ? ( November, I hope )

The DA is going to have a heck of a time proving premeditation, and he'll only get convicted of the lesser charge anyway. They may be doing this to appease the protesters, and calm the rioting down. Your cartoon perverts the meaning of words, INow. ALL lives should matter equally ! ( currently, they don't ) If we simply say "Black Lives Matter", but then Native Americans, or latinx, or Orientals, are getting mistreated, are we going to have separate slogans for each one ?

On a related note, the Canadian province of Ontario does not keep 'race' based statistics for fear that those statistics may be used to treat varying demographics differently. However, as different demographics have been hit by Covid-19 to very variable degrees, it is reconsidering its stance, at least in health related matters.

Seems China isn't just building islands in the South China Sea to increase their territorial limits. Seems they are not just scrapping the contract they had with Hong Kong that granted them independent governance until 2047. Seems they are not just threatening Australia for suggesting an independent investigation into the origins of SARS-COV2 to prevent future outbreaks, by cutting trade. Seems they are not just threatening Canada for detaining the Huawei CFO for possible extradition, by cutting trade and imprisoning Canadian nationals. Seems they are not just engaging in internet IP theft, Political influencing and dissemination of disinformation. Seems they also withheld the genetic decoding of the new virus for at least a week, and then stalled for at least two more weeks before giving the WHO pertinent information "all at a time when the outbreak arguably might have been dramatically slowed" https://www.msn.com/en-ca/news/world/china-delayed-releasing-coronavirus-info-frustrating-who/ar-BB14UB71?ocid=msedgntp Seems President Trump is right about at least one thing, during the whole of his Presidency s

Assuming Bill Maher is a good source, and there is such a study, we are left with the possibility that people touch each other, and infect things, indoors a lot more than they do outdoors. I also assume that they cough evenly, whether indoors or outdoors, but most Chinese wear mask outdoors, which 'contain' most of the cough droplets and retard spread. So yes, I can 'see' that statistic being factual. But you still haven't made the case that removing/replacing air quickly enough will prevent spread; and without either causing a 'wind tunnel' or extremely high costs which will make most businesses unworkable. PS: As Swansont keeps trying to point out to you, removing/replacing air is not the same as removing variable size droplets.

Ha-Ha. This wasn't a bakery, grocery store or hotel. They broke into and looted a Louis Vitton store. Did they really need a $3000 purse to survive ??? edit : x-posted with Janus

No wonder protesters get a bad name. Just like cops, a few bad ones tarnish the whole group. PORTLAND PROTESTERS LOOT LOUIS VITTON STORE https://twitter.com/ragipsoylu/status/1266634813152378887 so would you also say that if protesters want to be able to protest freely, they have to abide by the same rules and 'police' themselves internally also ,to avoid incidents like the above, with zero tolerance.

From your link, and its charts, it looks like your police forces are out of control, INow. They are shooting everybody ! I still maintain that this occurs because of your 2nd amendment, and the fact that police are trained to disable a perp, in case he is armed. Our Canadian police forces are trained to de-escalate situations. If they even pull their gun, never mind use it, they have two weeks of paperwork to fill out. Get rid of the guns, and you won't only stop the mass shootings ( although we just had another one recently ), but police may actually talk to people to resolve situations. The Police Killings by Ethnicity chart almost makes me afraid to visit the US. ( that is, if I could during a pandemic )

That's the attitude you develop when the only rights that matter are your own, INow. ( everyone else's rights be damned ) I hope none of you guys live near city centers and are safe from the violence.

I am torn as well. While I see the value of protest as a voice to people for the enactment of change, most of the time violence/destruction/looting are counterproductive. Although there have been a few good examples of protests where the police has marched with protesters, taken a knee, or even read names of past police killings. Even the 'chanting' of lines like "I can't breathe", "Black lives matter", etc. are counterproductive. While I agree America needs to have a long hard discussion about these matters, these 'slogans' seem to just drown out the discussion, and more like temper tantrums of little kids. They remind me of the sheep in G Orwell's Animal Farm, drowning out the other animals' complaints about the pigs in charge. Protesters should be speaking with one unified voice and be inclusive. ( and there's no better example of well-reasoned discussion than this forum )

He should get life in prison for breach of contract ?? Not for murdering a person, with video evidence ??

Maybe there was a history between D Chauvin and G Floyd. I read last night, that the two knew each other, having worked security together, in the past. D Trump may reconsider his Tweets now that protests/riots have spread to the capital. Apparently the White House went in lockdown last night. It doesn't look like the charges laid against D Chauvin have calmed the protests/riots very much.

Uh-Oh... Rise of Planet of the Apes ! "Monkeys 'escape with coronavirus samples' after attacking lab assistant" from https://www.msn.com/en-ca/news/world/monkeys-escape-with-coronavirus-samples-after-attacking-lab-assistant/ar-BB14LeVG?ocid=msedgntp

With any luck the officer will get convicted of premeditated murder, One thing I would add... In most other parts of the world, the police are trained to de-escalate the situation, and deal with it with minimal, or no force. In the US, because of that damned second amendment right to bear arms, the police are trained to take all offenders, no matter the crime, down with extreme prejudice. I remember a NY state trooper drawing a gun on me at 4:00am, 35 years ago, coming home on the highway from a bar. America's love affair with firearms seems to be related to a lot of problems in American society.

That simplistic analysis is for the case where the WHOLE floor is the inlet, and the WHOLE ceiling is the exhaust. In any real world situation where the inlet and exhaust vents are fractions of the area, Mr. Bernoulli dictates speed and pressure changes. I don't know how this idea deserves three pages of deliberation, but Swansont is right; your 'hand-waving' arguments aren't convincing anyone of its merits.

Nice explain, Markus. Reminds me of QM, where one can take advantage of symmetry in the Hydrogen atom, in spherical polar co-ordinates to reduce the 2nd order partial differential equation and get exact answers. But as soon as asymmetries are included, like you get with multi-electron systems of Helium and higher, the equations become intractable, and must be handled by numerical methods. with the number of EFEs the situation is probably a few orders of magnitude harder in GR. On the 'bright side' ... , the OP's stubbornness to abandon his simplistic idea, has allowed for a lot of these teaching/learning opportunities. And the rest of us who choose to seriously consider the information presented by you, Mordred, and others, are 'richer' for it.

If you consider the TWO masses as parts of the system, then the energy of the system is increased, and so the contribution to the energy density of the system is increased. The system, as a whole, will have a larger gravitational potential, but I don't think the 'attraction' between the individual members of the system will change. ( I could be wrong, but if Markus says the calculations are not trivial, don't expect me to do them ) Gravity is an additional source of gravity, simply because gravity is self-coupling, due to the non-linearity of the EFEs. IOW gravity gravitates. BUT there is no such thing asanti-gravity.

For the specific system where the kinetic energy is evenly 'spread out' over the system, then there is a contribution to the energy density. It contributes to ED because it is describing a system that has a higher temperature than the reference system. Not motion of the system. Seemed simple enough to follow...
