tap ... tap - tap-tap ...tap ...tap-tap-tap ... Do you hear that, Mr Anderson ? That is the sound of Logicandreason tap dancing as fast as he can, to avoid answering questions. There is no 'teaching moment' here. Stop giving his arguments air, and he'll go away and bother others.

This is just another semantic attempt to justify your excuses, how can it be imaginary, it's there in black and white; Yet if I said there's only males nd females, where the differences are much more pronounced, you, and others would be all over me. And it has happened. Do you have a clue about consistent arguments, or do you just throw 'stuff' at the wall and see what sticks ?

Who said 'merely stopping' ? But it should be the first step, as was explained to Phi yesterday. If you have a problem in your house, such as a water leak in the basement, that ruined your rug by making it moldy and stinky, is your first step to replace the rug so that it matches the rest of the nice decor, or do you fix the root problem first; the water leak that caused the 'injustice' to your rug ? You see, there's that intelligence at work ... Yeah, that's not going to happen. If you sling mud at others, then complain when it occasionally gets lobbed back your way, you should grow thicker skin. Last I checked, this was my OP, and I have the right to respond to anyone posting in this thread. If you want to be left alone, you can choose not to participate. ( I would much prefer you grow up, take some responsibility, and continue posting )

'That's right. It's all my fault. You were right all along and I just wanted to make it personal, while you and others were simply trying to discuss the topic. I'm so ashamed.' Sound familiar ( and condescending ) ? I thought it was obvious. ( nothing to do with being 'hard', INow; get your mind out of the gutter )

How about good laws that punish injustices when they happen,not try to fix them 200 years later ? How about a Constitution that enshrines human rights for ALL States, not the mix-match of different laws and rights for different States ? How about an impartial Supreme Court that doesn't do the bidding of the party that appointed them ? Need I go on ? Other countries have things like this. Also gun control and Universal Health care. Why must the most advanced country in the orld be the most backward in some respects ?

How is that working out ??? The first step, before redress of any prior injustices, is ending racism, Phi. It doesn't make sense, to me, that the mechanism used for mitigating the consequences of those past wrongs, uses racism. Just my opinion. If you want to call that 'doing nothing', then you're not serious about this topic. And after you all accuse me, and others, of wanting to do nothing, Zap acts all butt-hurt, when called out on it. ( I'm sure you can tell, but I don't give neg reps,Phi )

Back to the OP. In the 70s S Hawking proposed Hoola's mechanism as the source of Hawking Radiation, but it was found to violate a QM rule about information loss. Not transfer, mind you, but loss of information about states of infalling particles, which is certainly a 'measure' of entanglement. "It is now generally believed that information is preserved in black-hole evaporation.[5][6] This means that the predictions of quantum mechanics are correct whereas Hawking's original argument that relied on general relativity must be corrected. However, views differ as to how, precisely, Hawking's calculation should be corrected.[5][6][7][8] In recent years, several extensions of the original paradox have been explored. Taken together these puzzles about black hole evaporation have implications for how gravity and quantum mechanics must be combined, leading to the information paradox remaining an active field of research within quantum gravity."

That would have to be 'Silicon Shield', CharonY. They don't make breast implants 😄 .

That is a problem with 'idealists'; they are so convinced they are right, they won't even consider alternate viewpoints worthy of discussion. If you don't agree with their method, then obviously you want to do nothing, right Phi ? That seems funny, as most of you guys arguing this are American, where the problem is most acute. Hello ?!? Whatever you're doing ( if anything ) is not working. If You don't agree with them , they resort to thinly veiled name-calling. And, whether right or wrong, this accusation has been levelled at you many times before, has it not, INow ? Might be time to change your posting style, before people start thinking that where ther is smoke ( everywhere today ) there is fire. If you don't agree with them, they immediately jump to extremes. Voter apathy is at an all time high, even after 4 years of the most abysmal Presidency voters have ever, of D Trump. Voting against a bad system is everyone's obligation, yet Zap says MisterMack is 'victim blaming'. Do you guys want to have this discussion or not ? Because if you simply want converts to your ideology, no discussion is required.

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.
