Interesting... "My perspectives on these points differ because my approach differs" What does that tell you about any 'truths' gleaned from these differing approaches ?

I'm making the argument that culture is also a factor in how we express our aggressive tendencies. And since America has a gun culture, AND plenty of guns, that is the usual way aggression is expressed.

the assertion made by OldChemE that 'entertainment' violence leads to more aggressive behavior is certainly true. America has a gun culture, and this aggressive behavior is manifested through the use of guns for violent actions, simply because of the numbers of available guns. The argument put forth by iNow concerning Japan is not a valid one as they do not have a gun culture, or vast numbers of available guns. However if you Google 'Deaths by Samurai Sword in Japan', you will get multiple hits of attacks, murder, suicide and even mass stabbings/murders. The 'fault' for America seems to lie with that old, wild, wild west, cowboy culture.

It cannot work. Angular momentum is a conserved quantity. If the system has none it will continue to have none. the only way to change the situation is by external ( to the system ) effects, or by altering the system ( ejecting mass/energy ).

Never mind the box, John. What if you spin the universe around the astronaut ? Do his arms still fly out to the sides as they would if he was spinning ? ( this question has always fascinated me )

Google 'V Putin net worth' to see how many credible sources you get ( and not one Daily Mail ). He and his oligarch buddies are billionaires. How are you doing ?

Business fraud ??? I find that laughable, since the 'orchestrator' of his conviction, V Putin, has used the office of Presidency to make himself the reputed richest man in the world, with an estimated net worth of 200 Billion dollars. He is certainly the President of the new Russian Oligarchy. What of the rest of the people ?

Although my educational background is Physics, I've worked with dangerous chemicals for over 30 yrs. I remember doing involved documents and packaging of PCBs, for a one-time shipment to a high temperature incinerator in Western Canada, about 28 yrs ago at my first job in a chemical plant. The Polish guy ( new immigrant of a few years ) I was working with said... " Why so much trouble. In Poland we wash hands in PCBs."

Agree sensei... I still remember B Yeltsin standing on top of a tank when he and the Russian people stopped the military uprising in '91. I wonder which side V Putin would have been on. Seems that a few months after the 100th anniversary, Russia has a new Tsar. Wonder how long till the next people's revolution.

Truth is like reality. We have no way of knowing what it really is. We have models to describe reality, whether it be particles of the standard model, fields on fields or geometry of co-ordinate systems, but we never actually know what is real. Only what we can perceive and measure. Truth is the same,;it is the concept on which we base good or bad, right and wrong, etc., but it is also a perception, and therefore subjective. If there is an absolute truth as Koty is convinced, is irrelevant. Even the effect it has on us is filtered through our individual 'sense' of perception. And of course that leads to what is right or good for one individual, can be very wrong or bad for another

The Casimir effect cannot exist between 'real' quantum particles, such as atoms. Real particles and virtual particles are both a manifestation of the field. And although you could get interactions between photons if the EM field is strong enough ( see thread in Physics 'gravitational equivalent of Schwinger limit' ), I have a feeling any space-time distortion would be due to the intensity of the EM field, and not the absence of virtual particles from interaction with radio waves.

Give it a rest guys... This is the type of discussion that has been going on for years, and all its done is make the issue more polarized, and the situation worse. The only way to get to a solution is to work together ( Americans anyway, not you John ). No one says you have to give up your guns Arete, but do some of your fellow citizens need so many, and of such power? Should there not be better controls over who has access to them ? I think we all realize that something needs to be done. Stop the endless debates and contact your government and DEMAND that, if they want to be re-elected, they do something.

I think Gees introduced the topic of an elephant. Koty is the blind man holding the trunk, and trying to describe it. Strange is the blind man holding the ears and trying to describe it. Ten oz is the blind man holding a leg and trying to describe it. And Dimreepr is the blind man holding the tail and trying to describe it. Sorry Gees, but you've created a mess. I think you're gonna have to re-state and clarify the OP.

Most informed Canadians know that we have a trade deficit with the US, and just attribute it to D Trump shooting off his mouth without being informed. We also know that several of our industries are 'protected' unfairly ( dairy farming in Quebec ??? ). And yes I do agree that other involved parties should be at these talks ( Although Russia is quickly becoming a pariah ), if only to keep them somewhat sane.

Came into this kind of late, so all I can add is that it's all experimentally verified, and not just theoretical.

OK, now that you've explained yourself a little better, I concede, you are right. As Swansont once said... "Sometimes it's not about winning the argument, it's about making it better."

He will be missed. The physicist did a lot to popularize Physics and Cosmology in the late 20th/early 21dt century. And the man will be remembered for his valiant fight against ALS.

D Trump will be gone in a couple of years ( hopefully sooner, if impeached ), Ten oz. Kim Jong In will be around for a long time. V Putin also seems to have found a way to 'stick around'. As has now Xi Jinping, and many other dictators in all but name. ( even D Trump has mused about it, hopefully you guys will get rid of him before he gets serious about it )

That's us, silly and hilarious. D Trump doesn't represent me, I'm Canadian. And as an objective observer, I know who is the bigger whack job of the two. Lets try to keep that in mind.

I find it hilarious that you would single out D Trump as vacuous and untrustworthy in a meeting between him and Kim Jong Un .

The talk( s ) should definitely include China, South Korea and Japan. All are stakeholders in this 'spat'.

Never thought I'd have to defend Dimreepr... Don't go getting all offended Strange ( ) but you know that the observational evidence for accelerated expansion, and the need for dark energy, is based on measurements of the 'standard candle', type 1A supernovae. You also know that recent studies have confirmed the existence of several sub-groups of type 1A supernovae, of differing luminosities, which could throw the whole distance scale out of whack. Maybe there is no accelerated expansion and no need for dark energy. Sometimes absence of evidence just means we haven't found it yet.

There is no evidence of 'white holes'. A penrose diagram for a charged or spinning Black Hole does show time-like paths to an 'outside' universe. Our own or another ? But this could be an 'interpretation' of the Penrose diagram model, just as Feynman diagrams can have time reversal interpretation.

Yes, I would have a problem with four guns. But that's me. I had to wait a year and a half for the police to come and get a prohibited ( very short barrel/concealable, 22 semi-auto, Mauser,, probably last fired in the 50s ), that I found after my dad passed. Have no idea how he got it through customs when we came to Canada. But I do know some very responsible gun owners. Biggest problem I have with multiple gun ownership; If some of these guns go missing/stolen and are not registered in any way, are they not resold on the streets to criminals/gang bangers and used to commit crimes/murders ? Just the spill-over of American unregistered guns being re-sold in Canada is enough to cause gun related problems in cities like Toronto.
