Note 10.1 by far: http://www.samsung.com/es/galaxynote_10.1/
I have it, and also the phablet version, the note II. The S-pen is inmensely better than any pen for the Ipad and or the ASUS tablets. The included note taking apped is optimised for use in physics/enginering. The tablet is powerfull...
I would like to present the relevance from an slighly different viewpoint.
There are two asic options:
a) LQG predicts dispersion of speed of light. Them it has benn falsified.
b) It doesn't predict that dispersion. Them it doesn't predict anything measurable AFAIK. That's contrary to...
The really hot topic in string phenomenology are F-theory GUT's.
You can read an introduction here: http://arxiv.org/pdf/0809.3878v1 and here: http://arxiv.org/abs/0809.3452
That articles contain references to the relevant papers.
They are very impressive because they propose a model...
Hum, I have seen that you repeatelysay "SUSY/SUGRA is not renormalizable".
I am not sure why civilzed or others didn't mention it, but nowadays the general belief is that SUGRA (D=4, N=8 at least) is very probably renormalizable: See for example: http://arxiv.org/abs/0903.4630
A curious theory for sure. Before considering reading in depth your article there is a question that I would like to get answered.
If I understand right this model yields a rather minimalistic particle physics system. But cosmological and astrophysical observations strongly suggest that there...
The way D-ranes are usually related to type II is by means of the Ramond-Ramond fields that appear in the perturbative spectrum of stthat string theories. You need a source for that fields and it sis simple to see that point particles or on-dimensional strings can´t source them. Dp-branes, of...
Another aspect where, maybe, a QG could help is in analizing the possibility of toplogial change in classical general relativity.
Closely related to this is the possibility of existencence of wormholes (euclidean or even transversable ones).
As a curiosity (almost CF fashioned) I shoulp...
Gravitons? Uh?
Well, I´ll do a question for stringy people here. What is the S-dual of the graviton mode of a fundamental string?
I thnk that the answer could be interesting to understand what string theory has to say about gravity.
About the topic of the internet as a way of becoming a player my position is very clear. Yes, it allows it.
In fact with avaiability of arxiv, and other sources to have access to sophisticated science maeterial and blogs and phorums to discuss the only big difference of beeing in a university...
The M-theory si belived to be some strong coupling limit of some of the best known string theorys. In particular it first appeared as an strong coupling limit of type II A. The spectrum of D0-branes of type IIA seemed to behae as if theoy would be Kaluza-Klein modes of another theory. But KK...
If you see the usual pictures of D-Branes or you go with the idea of the brane univereses you would get the impresion that branes are infinite planes. But, are there more viewpoints?.
I guess that tehere should be, but I am not sure (that´s why I open the thread aftheall). The most generic...
Yes I was referring to the most advanced books, I didn´t read the divulgative ones, but the question was mainly intended for Benthemen.
About your skills in math/physics I hope they will be enought for at least understanding most of the subjects (hope your course of quantum mechanics would...
