Twistor Buzz

Lectures 4A and 4B are compulsory viewing. In the most deliciously outrageous display of presumption I have ever witnessed, Arkani-Hamed introduces twistor QFT to a group of beginning graduate students who have never even taken a course in old fashioned QFT. Moreover, he carefully explains to them why Feynman diagrams are redundant and quantum gravity has a better way of doing things. Wow. If I tried that, I'd be lynched.

Excellent talks. It's nice to see Nima enthusiastically discussing and extending material from Witten's Dec. 2003 twistor string paper. There are some deep mathematical structures at work here and multicategorical techniques seem highly applicable.

Hi, kneemo. Yes, it cannot be long until good post-stringy theorists realise the potential of multicategories.

Meanwhile, I may have lined up a decent waitressing job in NZ for the summer, although they want to meet me first.

sarcasm is something i've always struggled with.
i see now that the notion of you waiting on tables is silly.
theres no way an emancipated woman such as yourself would willingly reinforce sexual stereotypes like that.
