As a physicist, I say just renormalize the bastards, absorbing all those extra infinite terms into the ``dressed'' or ``physical'' or ``observed'' signifier, which then works just fine. (Cf. <a href="wm-james.html">James</a> on the ``fringe.'') <P>``Oh my God, it's full of signifiers!'' <P>(After a conversation with Jon Fetter, 21 February) <ul>Recommended: <li>Mattuck, <cite>A Guide to Feynman Diagrams in the Many-Body Problem</cite> [Since this undertakes --- successfully --- to explain Feynman Diagrams and renormalization at what the author calls a ``pre-kindergarten level,'' it should be quite accessible to the semioticians, especially those who speak so learnedly of ``differential topology.''] </ul>
