Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

Do the Twist

Everyone’s all a-titter about Witten’s latest, which appeared today. He studies Maximal Helicity-Violating amplitudes (n−2n-2 gluons of one chirality and 22 of the other) in perturbative large-N, 𝒩=4\mathcal{N}=4 Yang-Mills theory. After transforming from momentum space to twistor space, he find that the amplitudes are supported on certain holomorphic curves in twistor space. And he relates this to a computation in the open topological B-model with target space CP 3|4CP^{3|4}.

Arvind has a brief summary over at the Table. Me, I’m still wading my way through the 97 page opus.

Re: Do the Twist

I’m wondering how the comprehensive summary came to be posted just a few hours (if that) after the paper itself was available, in the wee small hours of Tuesday morning.

Perhaps there were back-channels involved… either that or an all-nighter.
