Besides, you just gotta imagine the figures (the first one) as dots (nodes) that are connected with lines (links).
Hi marlon,marlon said:I have a question though. In LQG gravitons should be viewed at as excitations of the quantized gravitational field. ...
Hi,marlon said:Hi guys,
i am still completing my quest for knowledge on LQG.
I have written a new text that talks about loops and spin networks.
Please, check it out.
Any comments or suggetions are more then welcome. Especially from Marcus...
If anyone is interested, i can also mail it to you...
I am sorry, but the two used figures were to big to send.
Hi marcusmarcus said:Marlon,
you have shown strong interest in making an
introductory text-book level explanation of LQG.
This is as we both know a real lack, and a big challenge.
Probably it needs to be taken up and tried by several
people---gradually the best way to explain and discuss
will be found.
A hopeful sign: today A. Perez (a long-time postdoc with Ashtekar
at Penn State who has now also with Rovelli at Marseille)
has posted his attempt at the desired "beginning Loop Gravity textbook"
Introduction to Loop Quantum Gravity and Spin Foams
His specialty is spin foams, so he makes a short treatment of
regular LQG and then more than half of the time he spends
discussing spin foams.
I am hoping that some part of this paper can be useful to us!
realworld studies should come first!marlon said:Thanks for the info Marcus
I will certainly check it out. The introduction on LQG has been postponed a bit becausei have a lot of work at college right now...
to be continued
marlon,marlon said:I wrote a little introduction on LQG because i have seen that many people ask similar questions on this topic...anyone that is interested can read it in my journal...
corrections are always welcome...
In English the word "fundamental" can be either adjective or noun.It is a very well established fact that gravitation and quantummechanics both have totally different fundaments, which makes it very difficult to unify them at “first sight”.
