generalisation of "z-w" to compact 2 dimensional spacetime by carsten007 on July 30th, 2013, 3:16 pm
hi my name is carsten from göttingen/germany.
as is well known correlation functions are translation invariant , if the qft in question is defined on the whole "plane" . as i`m primarily interested in two-dimensional cft. the plane would here be the complex one dimensional non compact manifold C itself. but as we want the notion of "future infinity" we soon have to compctify spacetime C, giving us the riemann sphere in the genus 0 case - lateron we stick to genus g.
remember the fermion 2 - point - function is up to a constant equal to 1/(z-w). now comes the crux:
this function z-w works well on C but not on R, where R is P^1 or (later) a compact genus g riemann - surface.
it turns out, that there`s no holophorphic function E(z,w) on R cross R with the property that E(z,w) = 0 iff z=w.
this is trivial,since there are of cours no holomorphic funtions on R cross R besides constants.
but - surprise - the holomorphic half form e := (z-w)/(squareroot(dz)squareroot(dw)) has ...

NLP by Mossling on July 26th, 2009, 11:03 am
As cooperative animals, when we engage in friendly communication, our cooperative thought-patterns come to the fore.

We reflexively enter in to a mutualist service-service interaction based around the use of words, with one individual taking on the role of authority on factual content, while the other problem-solves.

Where there are ambiguities in factual content, the problem-solver often uses his transderivational search faculties to patch over the gaps. Our eyes work in the same way - the blind spot where the optical nerve hits the eyeball is patched over using the surrounding information.

The problem-solver will always patch over factual ambiguities with conclusions using the data either side of the ambiguity - factual data which will have been provided by the authority on the facts.

If the person acting as...

What's it coming to? by ScatteredMind1535 on November 10th, 2015, 3:12 am
So i want to start off by saying, I am new at this. I was talking to a buddy of mine, and they said, "Why not find a discussion board and vent". Lol, i thought why not? So basically, I sit here everyday, and see the world around me. It is like everyone is controlled or manipulated. Everywhere you turn, there is a brand, a group, or random people telling you to, "live like this, act like this, look like this". I am not sure who it got to be this way, but it is absolutely ridiculous. I mean come on! This is suppose to be a "free country" That is absolutely a crock of S#@%! The only thing "free", is..... well nothing. There is a price for everything. I am only 32 yrs. old, so as some people say I am still a young one. Well young or not, I am by far not ignorant. I see how things are. I am not blind to my surroundings. The only place you actually can find some kind of "freedom", is your own mind. Only problem with that is, it has started to...

Railways and "The End Of History". by airth10 on April 24th, 2014, 7:39 am
I was rolling a model railway car over the cover of Francis Fukuyama's book "The End Of History". I wondered what it meant, if anything. I had just repaired the car and was running it on the book's cover to see if it was working smoothly.

It may sound mischievous of me thinking that a model railway car and The End Of History could have something in common. It sounds absurd. But as I stared at them both, wondering what possible connection they might have, it came to me that it had to do with an order, a railway order and a world order. Looking at the railway car I began thinking of all the railways in the world. And I thought, without railway systems and the networks they established throughout the world there would be no end of history as Fukuyama postulated. What he postulated is that humankind has arrived at a final world order in human governance. And as I see it, that final world order could not have come without the initial order railways brought to the world, which was...
