    J. Scott Carter from The University of Southern Alabama is a great new QG-TQFT blues performer
    See and listen here:

    Thanks to Dave Bacon!
    Here is the song text:

    The Quantum Gravity Topological Quantum Field Theory Blues

    I've been calculating
    I said I've been calculating
    calculating all night long
    Got a quasi- triangular Hopf algebra
    and I wrote down the coproduct wrong.

    I've been integrating
    integrating the whole day through
    I said I've been integrating
    integrating the whole day through
    Got a Chern-Simons functional integral
    and its convergent, too.

    I've been writing down knot diagrams
    converting them to braids
    Using the Alexander isotopy
    you know I'm not afraid
    I've been
    assigning modules
    to each of these six strings
    been doin' it for weeks now
    and I still don't understand a thing.

    chorus:
    I've got them old Quantum Gravity
    Topological Quantum Field Theory Blues
    I've got them old Quantum Gravity
    Topological Quantum Field Theory Blues
    And without NSF funding I think that you would, too.

    I've been [gen'rul]-izing
    to the higher dimensional case
    I've been [gen'rul]-izing
    to the higher dimensional case.
    I've got two-categorical indices
    running up and down the place.

    (repeat chorus)

    John Baez has some good words about Scott Carter's work (which helped to guide his own approach to Quantum Gravity back when he was actively doing QG research). He gives a link to the Youtube video and most of the lyrics as well.

    In the same blues mood, after he gives the Scott Carter lyrics, John Baez talks about his decision to change over from QG research to n-categories (where he has been making measurable progress over the past several years).
    I don't know any details but I think he decided to take leave of QG research back around 2005 and continued on supporting the PhD students he had then, in their QG research, until they all finished their disertations and got their degrees.

    So there's more to this blog-entry than just the Carter lyrics.

    It turns out that EDGE editor John Brockman has decided that the annual Edge New Year's Question this year will be WHAT HAVE YOU CHANGED YOUR MIND ABOUT, AND WHY? . And what Baez just posted is his response.

    The responses of other insightful noteworthies will soon be posted at edge.org

    all the website has now is a teaser "Coming soon the 2008 Edge Annual Question!" owtte
