Tomorrow Friday, at 9.10 in Paris, Ed Witten will deliver his reading on twistors.(adsbygoogle = window.adsbygoogle || []).push({});

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.

Anticipating Marcus, I will review Spires:
