    I A very interesting paper on orthodox quantum mechanics

    Well being orthodox in Q theory interpretations means usually to adhere to Copenhagen interpretation, as far as I can tell.

    Applied Blennow to follow up Altland?

    I'd recommend Arfken (I used it a bit for a third mathematical methods for physicists course, you can't have enough maths... that's why I am so MAD.... :oldbiggrin: ) I wonder which edition are they nowadays?... P.S I used it for the part that was needed for the course.

    Solid State Ashcroft and Mermin: revised edition

    being a ~40 year old student is really harsh with those prices of books just keep escalating.

    I Physicists disagree wildly on what quantum mechanics says about real…

    Computer says:No, none exists. at least not consistent. Either that, or it never halts.... :oldbiggrin:

    Music Nice track

    Baby, give it up.... off to SUSY...

    History An old 1990's lecture by Hawking

    you can try playing it with winamp, unfortunately as I said it sounds discontinuous.

    History An old 1990's lecture by Hawking

    I can't really remember from which website it was downloaded, I guess it's either Cambridge's cosmology old website, Hawking.org.uk or Kavli's website. According to the windows os this file was ripped into the CD (simple CDR) at the date of 01.01.1995. I copy paste it to my laptop from the DVD...

    History An old 1990's lecture by Hawking

    I have some old cd which I ripped to it back then an old lecture of Stephen Hawking from www. Unfortunately for me the quality of the sound is terrible (it's not continuous and it halts at times and then resound). I am playing it with winamp. Is there anyway I can fix it that it will sound as in...

    B What could prove this wrong? I'm having a dispute with friends

    How do you know that the diminished corners' square eventually converges to the circle?

    I Partial derivative of Dirac delta of a composite argument

    I guess you use the definition of a weak derivative. In your third equality where you interchange between: ##D(\delta\circ v)\partial_t \varphi## and ##(\delta\circ v)\partial_t D\varphi##, you forgot to multiply by another minus sign.

    I New Upper Bound of Neutrino Mass

    ##m_\nu^2<0## imaginary numbered mass?! :oldbiggrin:

    I If white holes were to exist in our Universe

    So theoretically, GR doesn't even predict their existence. Your answer is different than the other poster who claimed that they don't exist, therefore there's nothing to search for. For me it's like in Dynamical Systems that we have sinks and sources, so I can conceive an existence of white...

    I If white holes were to exist in our Universe

    Strings don't exist, therefore string theory is refuted. I thought it would take me more effort than that... cheers!

    :oldbiggrin: that's the way people are doing science nowadays... LOL
