Tomorrow Friday, at 9.10 in Paris, Ed Witten will deliver his reading on twistors.
At a high probability, this date will mark the sad end of this mathematical structure. It will become embedded in a hundred of papers unfocusing any previously known detail of Penrose' objects, which will adquire past tomorrow a completely new meaning. Of course it is happening since December, and Witten's article has already got over 40 citations.

A sad funeral call for Twistors, this Friday.
My contribution to the funeral is the last paper in arxiv where you can find the word twistor in the abstract
http://arxiv.org/abs/hepth/0406251 The affine ambitwistor space as the moduli space of SUYM in $AdS_5\otimes S^5$ Authors: BoYu Hou, BoYuan Hou, XiaoHui Wang, ChuanHua Xiong, RuiHong Yue By enlarge the $gl(2,2)$ symmetry with the twisted $U(1)\times U(1)$ reparametrization symmetry, we find a gauged WZNW action of YM field. The left and right twistor structure of left and right $\alpha$plane glue into a ambitwitor. The affine dressing symmetry enables to find twisted monopoles. We argue that its moduli space will be the moduli of N=2 SUSY.

perhaps the worms have already arrived even before the funeral but seriously if it is good mathematics then it lives on I just watched the 3 hourlong lectures that Penrose gave at princeton in october 2003, entitled "Fashion, Faith, Fantasy" they are on video that one can download from http://www.princeton.edu/WebMedia/lectures/ (the link is from Woit's blog) each hour is about one of the three things "Fashion" is about string theory "Faith" is about what he sees is wrong with Quantum Theory and why he expects a revolution in QM when gravity is included has anyone else watched the lectures?
