No, you don't have it right. People can be compensated for past injustices. Targeting a 'race' for compensation is racist. IOW, some black people may not need compensation, and some people of other groups ( a lot of immigrants in the past 250 years ) may require it. Did you not actually read my posts ?

On the contrary; that is exactly what it is. You had one group of people discriminate against another group, 250 years ago, for the economic 'betterment' of their Southern society ( free/cheap labor ) and we call it racism. We now have another group who wants to 'better' society by discriminating according to race again. and at the detriment of other groups in the case of Affirmative Action, because only so many positions are available. It is always one groupdeciding the fate/outcome of other groups. I'm of the opinion that should stop. You want to re-compensate people according to past injustices; that may be workable, but not according to race. What would you do about injustices suffered by Chinese people, who were the cheap/disposable labor that helped build railways in the 1800s ? What would you do about the Irish and Italian immigrants who came in the late 1800s, were treated little better than slaves, had to become policemen or priests to feed themselves, or turn to a life of crime ? Do you think all these other groups of immigrants who came to America in the last couple of hundred years don't deserve re-compensation for the injustices they suffered ?

The model for relativity uses the concept of space-time, and the distance, in space-time, between events. This distance uses the Pythagorean theorem for distances, such that the square of the distance is equal to the square of the spatial dimensions and the time dimension. To get a distance squared, from a time squared, it needs to be multiplied by a speed squared, which in this case, is -c2. This is the model; are you really travelling at c ?

D'oh ! How Homer Simpson of me. Forgot my CO detector is in ppm.

Haven't read it in a long time, and don't even know where my copy is, but it might be "Surely you must be joking, Mr. Feynman"

You will notice, CharonY, that nowhere did I say racism is 'fixed'. Racism is very apparent, especially in the Southern States, at European soccer matches, in Canada with the indigenous, and even in places like India/China. That doesn't mean that there aren't cases where'racism' is perceived, usually by a white person, where a black person has no such perception. And it also doesn't mean there arent cases of fake 'racism'; Jussie Smollet comes to mind. Of course, there arequantifiable injustices ( such as witholding loans ), but the problem with perceived injustices is that they exist in the mind of the perceiver; sometimes not in the real world. That's why I say, if you look hard enough you can find any perceived injustice.

I can see this method working on Earth ( aside from energy requirements ) as we only need to convert a couple of hundred parts per million of CO2 to O2 and CO. But in the case of Mars, getting 20% O2 in the atmosphere would also get you 20% CO. Definitely not breathable.

Being the OP, maybe I should explain the intent of the thread title. I have said this a couple of times before. When you go looking for racism, you always find it; even when it isn't actually there, such as with the cases of whiteboards, and blackboards.

CPT symmetry is based on Lorentz invariance and the locality of quantum field interactions ( as Markus has mentioned ). The symmetry is based on the total of the three properties and each individually ( or pairs ) can ( and have been found to ) violate the ruleas long as the emaining property ( or properties ) make up for it, such that total CPT symmetry is conserved. Since in alarge system ( Avogadro's number of particles ) there are many ways for these individual symmetry violations to occurr, while conserving total CPT symmetry, I don't think there is any way to guarantee that total CPT symmetry of a macro system is conserved.

monstrates the stability of this compact Tokamak system in reaching 100 Million degree temps required for Fusion. It demonstrated this stability for about 0.15 seconds. The obvious next steps are extending this stability time ( to be of practical use it eventully needs to be unlimited ), and, of course, you need to have a sizeable excess net energy output to be of any practical use. This won't happen tomorrow.

You're right; I should have iust said 8.6 keV, and avoided all this. And us canadians went metric in the 70s, so 'degrees' does not refer to oF, but to oC.

Yeah, it's supposed to be at least a couple of hundred more years before we get the Nomad and V y ger of Star Trek. And even then, there was an infusion of alien technology.

The only ones to use '100 Million degrees Kelvin' are the authors of the paper; I simply used 'degrees'. So, while it is true that you may know the correct usage of kelvin units, more importantly, you don't know how to reach 100 Milliion degrees in a small Tokamak fusion reactor 😄 .

That would be equalizing opportunity. And is completely justified. What some here are proposing is starting group B 50 feet ahead of the other runners, to make up for all the previous years of last finishes in the race. They then call this system 'affirmative action'. Is that where you were going with your analogy ? Without knowing what these factors are, and for what organs, I really cannot say whether the system is biased against blacks or not. You and I both know that there are diseases and organ disfunctions which affect different groups disproportionally, and it may be callous ( not racist ) to withold an organ from someone who will 'burn it up after a few years. Older people also don't get organ transplants after a certain age, as they are saved for younger people who will get fuller use out of scarce organs. Or is there a systemic bias against older people as well ? I would like a world where all people are treated as people, just as much as the next guy. My opinion on how we go about realizing this differs from some other members here.

Temperature of 100 Million degrees acheived in a 'spherical' Tokamak reactor, barely more than 3 feet across. Achievement of ion temperatures in excess of 100 million degrees Kelvin in the compact high-field spherical tokamak ST40 - IOPscience Another small step on what promises to be a rewarding but long journey.

You can twist your logic into a pretzel if it makes it more palatable and easier to swallow; you go ahead, I'm not having any of it. Racism is pre-judging a person solely on their apparent 'race', with no other discriminators. Surely you must realize, CharonY, that there are plenty of other, actually significant discriminators one must look for in an applicant for an academic position. Saying that things like qualifications and experience are also discriminatory just adds another twist to the pretzel. I wonder how a Polish or Hungarian white male, who immigrated to America in 1990, would feel when told that he did not get a loan because preferential treatment is being given to PoC, who could not get loans a couple of generations ago, right about the time Soviet tanks were rolling through the streets of his homeland. I wonder how he would feel when told he has to atone for the wrongs perpetrated by men wearing wooden dentures, who, 250 years ago, wrote a Constitution that started with "We the people ...", but in effect, was actually "We the white males ...", and who had no problem with slavery. Yet we think of those people as heroes, and cherish an unchainging Constitution. Eventually there will be push-back, Phi, and in 100 years someone will be discussing this same thing, and trying to re-compense the group of people who have been disenfranchised by this current round of re-compensation and affirmative action. And that will just tick off another group. And so on ... Maybe that's why everybody is shooting each other in the US, and nobody gets along.

Most definitely they should be compensated for any short-changed compensation. It is owed to them under the law, and the concept of equal opportunity. ItBut again that is not what we are considering. Take Zap's academic positions example, PoC have been denied these positions in the past. Your solution is to grant a disproportionate amount of academic positions to PoC, at the expense of other races, since there are only so many positions available. That is well-intentioned, but clearly discriminatory and racist, as the selection process is based on 'race'. I ( my opinion ) don't see how you fix the problem of discrimination by using more discrimination. It smacks of the Trrumpian idea ( sorry about the unfair comparison ) that you solve the problem of gun violence with more guns.

People with disabilites have always been disadvantaged in society. The situation has slightly improved for them by providing for equal opportunities through increased accessibility, anti-discrimination laws, etc. Would anyone suggest making able bodied people disabled to right past wrongs ? Why would we think it appropriate to do so in the case of racism and its wrongs ? The bolded part is the key.

Those are two different thoughts you're confusing together. I'm not against giving loans to people who've been denied loans because of racist practices. That's wrong; everyone should have equal opportunity to get a loan. But when you give one person preferential treatment by giving them an interest free loan, solely based on race, that is the very definition of racism, and you are continuing the practice that made the mess in the first place. The only way your idea flies is if you are after equality of outcome; and you still haven't presented an argument as to why that is a desirable outcome ( i'll wait, you may convince me ). The outcome I'm interested in acheiving is equality of opportunity, simply because I'm of the opinion that some measure of personal responsibility, once you have equal opportunity as everyone else, should determinepeople's lives.

And you can neg rep him if you choose, but if you've read the whole thread, he does seem to have a valid point. I'm not implying that Phi thinks in such a way, but the commentary he quotes does. Phi's comment about steering the ship in the opposite direction, on the other hand, implies fighting racism with racism, which to me, is a non starter. The ship only needs steering in the opposite direction to arrive at the same place, IOW, equality of outcome, while taking away opportunity from some to rght past wrongs, and which, to me, is also a non starter. I much prefer keeping the ship sailing straight; there is no guarantee of equality of outcome, but it provides for equality of opportunity for all What you make of this opportunity is up to you..

You've got to be kidding. If Russia had attacked Germany the front lines would be somewhere East of the Urals, and Russia would be begging for peace.

And after a year and a half of this invasion/destruction of a sovereign country, some people are still bending over backwards to excuse V Putin's aggression. 'Patriotism is the virtue of the vicious." Oscar Wilde

'Better' is subjective. And here I thought cheese was off-topic

Hate to break it to you, buttercup, but you were made aware of the rules when you joined. That was, in effect, your contract and consent, because you had the option of not joining if you disagreed with the terms and conditions. But maybe your lawyer ( Lionel Hutz ? ) can better explain.

Just another angry old man. ( welcome to the club, Roger ) Only problem is, he has a 'platform' that reaches many.
