I would appreciate if someone could give me some idea about how to solve this sampling problem. I have a distribution W(x,y) of fields x and y characterized by a population of N vectors (x,y). I have to sample x and y fields according to a second distribution Q(x,y) which is related to W by...

I guess I miss the point in one thing. If you consider the black hole and the universe as two entangled systems, measuring the state of the universe would mean that you know the microstate of the black hole, isn't it? If you are external to the black hole, this cannot be, right? If someone could...

Actually, that is not correct. What you suggest is a hidden variables explanation and,a ccording to Bell's theorem, they must obbey some inequalities which are violated in the quantum case. Although the question is not settled, there are experimental indications (not without controversy) that...

I have a draft of the book, which is still incomplete. I can ask his brother if he has an updated version and send to you by email. :smile: I share with you (and Nestor and Ariel as well) the feeling that this information/inference approach can lead to a unification path somehow. Nestor is a...

I made my Ph.D. with Ariel's brother Nestor and I know a little about his papers. He also is writing an interesting book on Information Physics. When I first read Smolin's paper it reminded me at once Ariel's paper. Ariel's approach is classical and I don't know how it should be quantized. It...

I'll try. Thanks for the suggestion.

Seems that in 1968 Kac gave a seminar where the first idea of the Replica Trick appeared. It was the Trodheim Theoretical Physics Seminar. Do someone has a copy of this work or is it lost?

Ok. Now I found it. My file system is FAT32.

Sorry, but I'm not a computer scientist (just a physicist...) and I have not any idea about this. The only thing I know is that I've already have this problem in the past with floppies, but in that case I've simply thrown them away...

I bought a Flash Memory Drive and I was using it in my computer in the university, which runs Linux, and in my computer at home, which runs Windows. Today, suddenly, my comp. at the university simply does not even recognize the flash drive, although it's still working perfectly on Windows. Does...

Thanks a lot for the references. I'll look for the books in the university's library (although a first search I made was not very promising). Indeed, maybe you would help me with the question which lead me to look for Morse Theory. I'm trying to identify if a critical point of a functional...

Does anyone know of resources about Morse Theory online? I'm looking for an introductory text.

Hmm... Thanks. I'll try to do that.:smile:

I'm trying to use xfig in debian but when I try to write a text in my pictures I get the message: 'Can't find -*-times-medium-r-normal--13-*-*-*-*-*-ISO8859-*, using 6' What is annoying cause I cannot change the size of the font and the text is so small that I cannot read it! Okay, I know...

Superpositions of states are a basic asumption of QM. According to the theory, the particle is in a superposition of states of an observable (momentum, for example) until a measurement is made. After the measurement, the particle goes to one of the eigenstates of that observable. Exactly how...
