He is talking about perturbative gauge theory amplitudes and the idea of interpreting them in terms of strings in twistor space.  He motivates this by noting that AdS\/CFT is useful for understanding gauge theories at large g^2N, but at short distances asymptotic freedom implies g^2N is small and to understand gauge theory in terms of strings you need to do so for all g^2N.  He warns &#8220;I can&#8217;t promise that what I&#8217;ll explain will turn out ot be useful in a string description of QCD, but at least I&#8217;ll tell you interesting things about perturbative gauge theory!&#8221;.<\/p>\n<p>For something completely different, the latest on the Landscape is that, at least <A href=\"http:\/\/www.arxiv.org\/abs\/hep-th\/0407043\">this week<\/A> it predicts low energy supersymmetry, maybe.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Witten is lecturing at a conference in Crete this week and some of his transparencies are already online.
