Symmetry Magazine

SLAC and Fermilab have joined forces and replaced their “FermiNews” and “Beam Line” publications with a new one called “Symmetry”. I like the title; it’s nice to see that the major US particle physics labs are supporting a publication about group representation theory.

    The Nature of Quantum Mechanics by Gread’t Hooft

    But below we have some guiding principals to live by?

    Question:In conventional QM and QFT unitarity is the consequence of the time translation symmetry of the dynamics. In GR there isn’t, in general, an analogous notion of time translation symmetry

    A lot of people (in fact, most people) argue that this is not a problem. They are wrong. It is very closely related to locality. How can you have locality in a theory where there is no a priori notion of distance? This is really a serious difficulty, and it had made some deep thinkers (read: ‘t Hooft) so desperate that they are even willing to abandon quantum mechanics. In the beginning of the talk at(above links in my postings) , ‘t Hooft explains that he simply believes in locality, and that this is why he explores these weird ideas about hidden variables. It is interesting that the inventor of holography has such a strong belief in locality.

    It all sounds spooky to me. How do you identify the smell of apple pie? It tastes like…..?:) From one island to the next????

    Mathematics is always a continuum, linked to its history, the past – nothing comes out of zero Atiyah

    How soon I forget sometimes:)

    I have a story about two monkey’s on a island that I thought funny, but hey, we can work with “shit for brains”, like mom’s apple pie wafting through the neighborhood.:)

    It’s the trivial things in life that make the difference. The re-sizable/scrolling window is indeed a boon. Its former immutable form was almost as distressing as the recent (let’s not mince words) ‘shit for brains’ interlude. Thanks

    Thanks! That worked beautifully.

    Hi Danny,

    I made the change suggested on the link you posted, resizable comment windows seem to work now.

    About Atiyah’s work:

    He’s actually one of the clearest writers of any mathematician, so one piece of advice is to just get ahold of the five volume set of his collected works, and try reading, starting with the expository pieces he has written, of which there are quite a few. Unfortunately I don’t know of many more readable expositions of Atiyah’s work than his own. For certain specific things that have made their way into physics (such as the basic index theorem for the Dirac operator), there is some physics literature.

  6. D R Lunsford says:


    What would a set of books for “Atiyah 101” look like? I want to understand this business with the index theorem, at least as far as is necessary for physics.


  7. Peter says:

    Hi Danny,
    If someone can point me to a source of information that explains how to do this, I’ll look into. In general I don’t want to invest much time in messing with Movable Type. As far as I can tell the thing to do is to migrate this at some point to Word Press, a project that will have to wait for some mythical point at which I have some free time.

    OT – Peter, is there anything you can do to MT so that IE popup windows are not fixed in size and menuless? It works fine on Linux but not on Windows (go figure).

    (In case I was not clear, the posting window cannot be maximized or resized at all, in fact.)


  9. D R Lunsford says:

    Well I for one endorse the defense of Bumo-er-Lubos, and hope that he will not in future refer to excrements in any place or context.

    But we should stick to physics, yes.

    ..and he has been known to express his interest in loop quantum gravity by suggesting that its practitioners be deprived of research funding. (See some of postings on sci.physics.research.)

  11. Fabio says:

    You’ve got it backwards. It was Lubos who introduced “excrement for brains” into the discourse here. He’s shown himself to be quite thin skinned and quick to go personal when someone starts to get the better of him.

  12. Anonymous says:

    C’mon. Whoever is writing these mock Lubos Motl entries needs to stop. This blog is about physics, not mockery and insults.

    Some of you might not realize that the reason why Lubos spends any time on this website is that he is, at least in part, sympathetic to some of its views. Quite reasonably, therefore, he is compelled to defend string theory and his research. His point of view is defendable.

    It would be a shame if Lubos and other string theorists stopped using this website on account of unprofessional attacks. Let’s keep our eye on what the real issues are and debate them.

  13. ltom sobul says:

    This is obviously an implicit endorsement of string theory by the two top US accelerator labs, since string theory has more symmetries than any other theory.
