Is any operation valid without identity ?

So, I'm guessing the D Trump Presidential Library is very sparse.

And I said For gross contaminants, like 10 k or 14 k gold, lab grade equipment should work. But you may be right about higher purity grades.

Except that mass is also ambiguous. Some of these problems seem so simple, Markus, such as quasilocal mass, in GR, being indicated by the difference in curvature of a two-dimensional sheet relative to Minkowsky flat. The hard part seems to be finding a method for which mathematical tools are available so as to allow computation. More of a mathematical problem than a physical one. Then again, at this level of theory, there's very little difference.

I guess it is true. The human mind looks for patterns and connections; and often finds them when they are not really there.

various types of gold are alloyed to silver, copper, zinc, etc. This affects the density. I would think accurately weighing the sample, and determining its volume by water displacement, would yield a density which can be compared to pure gold. It would be as reliable as your weighing/measuring equipment.

Yeah ! Stop teasing us 🙂 .

So far the situation in the waters around Taiwan is all bluster. The number of intrusions into Taiwan's territorial waters and warning zones are worrying, however, as there is no way to distinguish an actual attack from just another intrusion. I sure hope that Taiwan's missile defense systems are 'locking on' to every single intrusion into their airspace and territorial waters, as an indication to the PLA that they could, if they so choose, take their assets out. I remember in the run up to the 1996 Taiwan Presidential elections, the PRC similarly got their panties in a knot, and started firing missiles into Taiwan's waters. President Clinton sent the 7th carrier group ( Nimitz ) to sail through the strait of Taiwan, along with the 5th carrier group ( Independence ) as back up. I don't think anything of the sort will be tried this time as China has grown much more bold, if not more powerful militarily. But I'm sure a couple of US carrier battle groups are on their way to the area, and US Air Bases in Okinawa and others in the west pacific are on alert.

I noticed you said "so many of our fellow citizens", "some white men are mostly", and "many are mad". I guess that means you and CharonY get the point I was trying to make. Much appreciated. Oh, and none of this was in any way supportive of Greg A's ideas.

So your solution is to judge theiir 'goodness' by appearance, the same way people have judged blacks, Muslims, gays, etc. in the past ? I thought we were trying to get away from that; to build a fair equitable society where people are not judged by skin color, gender, sexual orientation, religion, etc. Is that too horizontal ? Strong association is much better than blanket statements concerning all men. Thanks for that. One of the most attractive women I can think of, is Linda Hamilton in Terminator II, carrying a Franchi SPAS shotgun. Not exactly a 'shrinking violet' relegated to the kitchen, or raising babies. Then again, my mother was a strong woman, who, unfortunately passed away young.

And I'm saying ( again ) discrimination is bad, no matter who it's applied to. We are all people, and should be treated as such. You seem to be saying that some are 'priviliged' in our society, and so it is OK to paint all 65 year old white males with the same broad brush as misogynistic, drunk,wife abusers. The argument seems to be, I want a 'horizontal ' scale applied to bigotry, while you want a 'vertical' scale, with differing levels of bigotry being applicable to different people. Am I using your terminology accurately ?

I see. There is nothing arbitrary about vertical fairness, or horizontal fairness. You can even assign a 'degree' of difference between the two. You are just one step away from a mathematical relationship bettween angle and 'fairness'. And I was asking Phi for elaboration, not your 'interpretation'. I guess that includes you; but I suggest you speak for yourself. And I tought that's what I was doing by politely asking some members not to paint a group with the same broad brush. Not calling anyone a shitheaad; but some of their behaviour ...

Would be interesting to know if any of the people you've banned over the years, took part in the mentioned study, Swansont 😄 .

We seem to be discussing two different issues. In one case a substance is injested/absorbed/inhaled that produces a type of response which harms the system, and causes inflammation or outright cell/system death. It is a 'poison' to the cells/system. In the other case, you have essentially a harmless substance, that is injested/absorbed/inhaled, and which causes an unwanted over-reaction by the immune system. Typical would be pollen and the overproduction of hystamines by the system. ( some, like bee stings, would involve both reactions )

I would be careful in saying 'some men' and not simply 'men', implying all, and in which case you'd be proving Greg A right, with your gender bias. If I made disparaging comments about women, as some have about men, or a cultural group like Middle Easterners, without stipulating that it is a small subset, I'm sure the usual suspects would be handing out demerit points like Halloween candy. Just saying ... BTW, Phi, you really seem attached to this vertical hierarchy vs. horizontal group of equals. I think what is important is not the arbitrary direction that you assign to it, rather, the inherent fairness and equity. A fair monarchy is more desirable than a Marxist Politburo. ( but maybe I'm still not understanding you properly ) Further to Swansont's comments, some are so rich , they can go into orbit in their own rockets in vain attempts to outdo each other ...

All very true INow. Those methods are regularly used by the 'right' in your country. However, the ''left' are not beyond reproach, and do need to shoulder some responsibility when they screw up. No matter how much you want to bend over backwards to excuse their behaviour, because it is nowhere near as bad as the 'right'. Maybe I should quote your line back to you when you next blame the 'right' for all the problems in your country that are actually caused by extreme political polarization.

To be fair, most people don't know what they don't know. ( do I sound like D Rumsfeld ? 😀 ) It is when they insist that their limited knowledge some how gives them greater insight, as if the ones who actually do have knowledge have been brainwashed, that the problems begin.

Pssst ... I think he's an incel ...

He'll probably just take his clown show to the next forum, and give them a headache.

Then why would you write something so wrong as 'conservation of mechanical energy' ??? Energy ( of all forms, even mass ) is conserved locally; not globally.

While genetic programming is 'hardwired', and affects populations because it is passed on from one generation to the next, the immune system works on a 'learned response', and why allergies come and go with age, change severity, and are not passed on.

You should learn some first ...

Absolutely. You don't seem like the kind of person I'd want to get to know any better.

I don't think anyone has, as there is no such thing. Quit wasting forum bandwith with idiocy.

Can we ban this jackass already. I'm getting tired of the idiocy.
