Here is an idea.. Our brains are unique but like colors they are in the same category(the Mind). Can this be an explanation for this claim?

Sounds trivial - my brain is a brain.

But evidence from quantum physics suggestive of life after death ...

Bad form replying to a mod note.

Anyway there is no evidence from quantm physics about life after death.

Have you any recommendations for a math textbook that treats this topic in some detail, at undergrad level ?

Kaku sketches some things in his book on quantum field theory. It is not the best, but it will give you something to start with.

I tend to find a journal and look for the IF on their website. It is usually quite clear if that have one.

I have never paid for a publication to appear - so I don't know how the cost of open access compares across journals. I don't know if this is linked to IF.

To be honest, I would forget Nature as place you try to submit your first paper. Unless others who know your work - say PhD supervisor or something suggests it. As you are maths focused I am also doubtful that Nature is that interested, but I could be wrong. The best thing to do is to submit to journals that have published the papers you are reading as part of your background work.

Ok, thanks for the pointer, I haven't studied that specific topic yet. Goes on my reading list now

I can't recall much from the top of my head - but you are looking for irreducible representations of the (complete) Lorentz group. It is not just tensors you are interested but also spinor reps.

1) do such journals care that from which (type of) journals our article's citation-references have been done

(the equivalent question is whether will it be better us to cite and give references from just that journal we would submit our articles?)

I don't think they really care - meaning the editors and referees - what journals the reference you give are in, as long as you reference are sensible and up to date.

2) how the ranks are being given according to this website : http://www.scimagojr.com/journalrank.php

I think that they generally agree with other methods of ranking. The Impact Factor seems to be the one most people use. So find a journal that has publsihed the papers you are reading and rank then using IF. (Not that I like IF, but it is what people use)

3) does this mean that if one journal is "open access" ,then it will not be well known journal

and I see we are able to make show all (only) open access journals via using item on the website (given above) , but let think we found any journal by google search ,then how may we control whether it is open access or not?

Some journals you can pay to make the articles avaliable to everyone. Some good journals have this option.

You need to look at the representaion theory of the Lorentz group...

Is it not just the ratio [math]R^2 / M[/math]?

You can model things that don't exist in the real world.

It depends exactly what you mean by model - we can construct theories that do not match nature well. Anyway, I still don't see how this relates to time being an intrinstic part of mathematics.

15,000 and counting.

"...firing of nearly 8,800 policemen, and the arrests of 6,000 soldiers, 2,700 judges and prosecutors, dozens of governors, and more than 100 generals – or just under one-third of the general corps".

It looks like the country really is going to shoot itself in the foot here.

blue89 - I hope Erdogan and Yildirim's changes don't change things for you too much. Stay safe.

What happened ? Did the Polish communist party that existed before the war take the side of the Soviets against other Polish who opposed them ?

Details are for another thread... but essentially the communist party - Polish run but set up by Moscow - made sure that those who could put an argument together why Poland should not be communist were got rid of. The same happened to the Polish Free Army that fought the Germans, many were got rid of.

Goodbye democracy. Hello Islamic rule. I think what we are seeing now is a concerted consolidation of Erdogan's power. But, at the end of the day, that way is being chosen by the majority it seems.

This is the worry... others have done similar things in the past to keep their position. A good example is the near civil war here in Poland after WWII.

The revenge of Prime Minister Binali Yildirim is worrying. We have seen this kind of action before throught history - chop off the heads of those who can think for themsevles. Same of the purge of the armed forces. We have seen this before...

"More than 1,500 university deans have also been ordered to resign and the licences of 21,000 teachers working at private institutions revoked."

Dude our time differs for an active discussion. When you are fresh and awake it's probably the time for me to hit the sack and vice versa.

So, still no then.

If "space" or "distance" is a property of time then there's not really such a thing as "diameter" for a circle.

Sorry for the late reply...

You are confusing the physical world with the mathematical world. There is no problem with the notion of the diameter or a circle.

Do you really want to discuss this and the book in general?

So no then ...

I don't see that what you have posted makes any points or asks any questions. What is it you want to discuss?

Hunt down the book I suggest... otherwise you are just arguing from ignorance. (Not that I am sure what you are heading towards here)

Not my field at all ... but various people have worked on the mechanics of animal motion. You should see what the literature says on the subject - for sure a change in gravity is ruled out.

See if you can find Robert McNeill Alexander, Dynamics of Dinosaurs and other Extinct Giants, Columbia University Press, 1989.

Does that mean you accept my answers as valid, or at least possibly valid?

Not at all... it just means I have no plan to keep beating my head against a wall. It was fun, but I don't see that I nor you can gain anything from us continuing.

Good luck with the 'physics'.

This is all off topic... please say something about wind and atmospheric physics next. We maybe able to help, maybe not, but please ask.

I think I'm done... over to Mordred.

And, while he missed out the fact that the Earth's rotation is a major factor, he did answer your question.

Thank you John.

let alone his theory of relativity after he worked on the atom bomb only one could suspect much worse outcomes for instance capturing a particle of the sun and exponentially expanding it isnt a real threat......not when Eisenstein creates isotopes that eat shit up

What are you talking about and what has that got to do with your opening post?

What is it you want to ask or discuss about geological sources of energy?
