Hey !! Who says Canada's isn't an ideal climate already. We have all four seasons, spring , summer, fall AND winter. Not just summer all year round like the southern US, or 'dreary always', like the British isles.

Its not just the lower density of Hydrogen and Helium which explains their scarcity in Earth's atmosphere, as Sensei has explained. That would just lead to a 'stratification'. If the mean free velocity of a particle can exceed the escape velocity, then that particle/molecule can leave the Earth.. When the Sun first sparked up, its radiation was enough to 'blow' away all of mercury's atmosphere ( it being a small planet with low gravity. The next three planets lost only their lightest gaseous atmospheric elements, while the last four, being massive and distant ( cold >> low free velocity ) retained even Hydrogen/Helium

There's 'stuff' in Soylent too, Endy. "Its people ! Soylent Green is made out of people." C. Heston, best NRA member, ape fighter and Red Sea parter, ever.

How many children die because of a parent's negligence every year ? How many children die because parents expose them to 'unsafe' conditions ? How many make national news ? The fact that a gorilla had to be put down because a negligent parent exposed their kid to unsafe conditions, has made national news. Would there be this much discussion if the zoo staff had done nothing and the kid had been injured ( or killed ) ? I think the 'best' of the bad outcomes was chosen.

I have used, and still use hair gel on occasion ( when I'm getting fancy for a special occasion like a dinner/date ) but I've stopped coloring it. I'm starting to like the George Clooney, salt n' pepper look. You will get build-up after several uses, even shampooing daily. If using it daily, suggest using dishwashing soap like Palmolive, once a week to cut the build up. ( however,if your hair is thinning that may be too harsh ) Those other two guys are probably jealous, because they've lost their hair. But, I gotta ask, why are you asking this on a science forum ?

If its an acid you're looking for, hydrofluoric acid will etch glass or quartz. Be careful with that ( google the hazards, its nasty stuff )

Maybe the equivalence principle can simplify things for you. Consider that wherever you feel the force of gravity ( i.e. weight ), you can be considered to be accelerating. A far away observer ( where space-time is nearly flat ) will measure your time to be dilated. So both acceleration and relativistic velocity will produce time dilation. And as has been pointed out, SR's time dilation is symmetrical between the two observers because velocity is relative. GR's time dilation is not because acceleration is not relative

But isn't that Politics, and not Government, Delta1212 ? Politicians will always be just marginally better than lawyers in some people's eyes ( no matter how hard they try ). But is the government getting better or worse ? I realise it will always focus on the US, so lets discuss the government of the US. Is it getting more compassionate, or is it getting worse ? Are we looking out for our fellow population by increasing Socialsm, or is it every man for himself by increasing Capitalism ? On the one hand wealth is being concentrated at the top percentage of the population, but on the other, social programs have improved to the point where very few are destitute and hungry. What is the general consensus. Is America on the way up, or down ? ( or does that depend on how far D Trump gets in the election ? )

Have you actually read the Metcalf study that CharonY spoke about, John ? The conclusion it draws are that management/labour relations are extremely important in determining the effect on productivity. Good relations, such as in Japan and Germany, may lead to increases in productivity, depending on other factors such as competition, investment, etc Bad relations, such as in the US and England, lead to worse productivity ( but things are changing for the better )

Since my previous post informed you that the techs where I work decided this past December to have a union represent us, you know that I'm NOT opposed to them. What conclusion should I draw from that, John ? And what is it they say about people who resort to name calling in an attempt to win an argument ? Look, I think unions are necessary, and will continue to be. People will always try to take advantage of other people. Its human nature ( and this was already discussed in the first page of this thread ). And also because of human nature unions TEND ( i.e. they have a forcing towards ) the 'lowest common denominator', because people tend towards the path of least resistance ( read as 'quite a few of us are lazy' ). But if I was an engineer ( and earned less salary ) at my place of employment, and chose to put in long hours of dedicated problem solving, I could advance to Ops Manager or Facility Manager. Alas, my current position as a unionized employee doesn't allow for those kinds of goals. In effect, unionizing took away some of the incentive to better myself. Like Communism does. And that is why I have and continue to maintain ( as others have also ) that Communism/Socialism must be balanced with some Capitalism. Now perhaps you'd care to explain why I'm an idiot for thinking this way. BY the way John, I love cherries but really dislike the pits in them. According to you, I must dislike cherries, or be an idiot. ( who thinks like that ??? )

Of course, CharonY. I probably wasn't clear enough, but both Honda and Toyota have Auto manufacturing plants here in Canada which are not unionized, ( and the Koreans had a plant in Quebec which has since closed ) as opposed to GM, Ford and FCA, which are all unionized. And you're right, I don't know how you'd assess productivity, but I do know their employees are very loyal. I do seem to remember reading that even where Toyota and Honda have unionized workforces, they tend to work with the company in a non-adversarial manner. Which seems to differ from the North American style of doing things. But none of this changes the fact that I've never said I'm against unions. Nor Communism.

So now Phi and Delta are criticizing me for my phrasing, and John thinks that because there's a quality concerning Communism and unions that I don't particularly like, I must be opposed to them. I have stated numerous times that they are necessary. Maybe if you read people's posts you won't have to constantly demand answers ! And yes John, I was in a unionized workforce for approx. 15 yrs. At my current employment I've been a non-unionized, salaried employee for 13 yrs, but our management team was recently brought in from the Southern US, and made life miserable for some. So much so that this past December we unionized. As for evidence, not that anyone else has provided any to the contrary despite your assertions, I submit the productivity of American Auto plants, with their unionized labor force vs the productivity of Japanese and Korean Auto plants. You tell me which are unionized and which employees are treated with more respect.

I'm afraid I have to say the same thing as Sensei did, John... "What on Earth are you talking about ?" I suggest you re-read post #2, where I state... "a lot of us would suffer needlessly. Just as workers would without protection." Does that sound as if I'm opposed to labor unions ? Sometimes they are needed, just as Socialist policies are needed to ensure a 'just' society. Sometimes they are NOT needed. And that is the basis of my comparison to Communism.. If I'm unionized, and I can never earn more money, get more time off, or receive better benefits than my fellow employees, what is the incentive for me to do a 'better' job ? Simply adequate will do. And that is why I say both unions and Communism tend to breed the lowest common denominator. And why I believe Communism and Capitalism need to be in balance. The weak and needy need protection and a hand-up. But they also have a need to strive for something 'better'. I'm glad I gave you the opportunity to get some information 'out there'. And I hope I answered your questions to your satisfaction ( but I suggest you could have done that yourself by re-reading my post )

All of the things that you mentioned, John, are now protected by legislation in western countries. Are you then saying labor unions have no further role to play ? ( see, I can 'twist' your words too )

Even Spock had to modify that rule, iNow.

They don't build bridges like they used to.

Both Communism and Capitalism are prone to corruption, as are all systems of governance. Lets not pretend Communism under J Stalin or F Castro was the ideal Communism. Those leaders amassed great wealth and power. Nor do we have the ideal Capitalism in the US. Not only is it tempered with some socialism, but, there are certainly barriers to bettering oneself. And it is also a corrupted system. We are after all, a species which tends to take advantage of, and exploit, our own kind. Its built into our genes. Survival of the fittest and all that. Sometimes all we can do is hold our nose and pick the option which stinks the least, Sensei.

Certainly, a 'just' society has to balance the common good of all its people with the heed to better oneself. Communism/Socialism and Capitalism have to co-exist, but the devil is in the details. The 'right' balance is obviously going to be different for different people. ( and sometimes different for the same people, at different times in their life )

Come on John. I know you read the rest of the post. Or are you just picking and choosing parts of my post to argue with ? ( come to think of it, I've often done the same thing )

Well, what is the reasoning behind your thinking ? Communism is a lot like labor unions, they both tend to produce the lowest common denominator. Everyone uniformly poor, and everyone a bad worker. Unfortunately, if it wasn't for shared resources in our society, which is what Communism or Socialism refers to, a lot of us would suffer needlessly. Just as workers would without protection. So is it a necessary evil ? Or an undesirable benefit ?

Agree with what you say Bells, but throwing out 'sexist' and 'homophobic' labels right out of the starting gate does no-one any good. I have used bathrooms which although not designed that way, were being used by both males and females ( long line-ups in crowded nightclubs in my younger days ). There was never any 'shy bladder' effect, even when the girl in line behind you was telling you to hurry, because you'd usually had plenty to drink. And no, I didn't stick around to see how she was gonna manage at the urinal.

Everything that supplies more calories than it takes to digest CAN be fattening. Your body can burn carbs, fats and proteins. Its the amount that matters

Its a sneeze, fer cryin' out loud, get over it. I really don't think you can sneeze at will, so I don't think you can 'maliciously' sneeze on someone. Maybe your after-shave stinks and caused the sneezing.

Hi Markus. Nice explanation of the EFEs. Have never seen them explained so simply before. ( still remember your GR stickies on that other 'forum' )

Wow ! OoooooK... You seem to think you know a lot about Einstein and scientific history. SR was not discarded by Einstein, but was a precursor to his groundbreaking work with GR. As a matter of fact, if Einstein hadn't published in 1905, chances are good Poincaire would have presented a working version of SR within 5 to 10 yrs, as he was that close. His work with GR, however would probably have taken 50 to 100 yrs to equal ( if ever ), as there was no-one even remotely close to what he accomplished with curved space-time geometries. I suggest re-reading his 1905 paper. While it may be more limited in scope of applications, it is by no means redundant.
