Sorry Louis, but try again, please, for your address was wrong in the list!!!! --Pedro (I have just discovered, in a trip pause) BlackBerry de movistar, allí donde estés está tu oficin@ From: Louis H Kauffman <lou...@gmail.com> Date: Tue, 22 Mar 2016 17:56:06 -0500 To: fis<fis@listas.unizar.es> Cc: Pedro C.

Dear Plamen, It is possible. We are looking here at Pivar and his colleagues working with the possibilities of materials. It is similar to how people in origami have explored the possibilities of producing forms by folding paper. If we can make hypotheses on how topological geometric forms should develop in a way that is resonant with biology, then we can explore these in a systematic way. An example is indeed the use of knot theory to study DNA recombination. We have a partial model of the topological aspect of recombination, and we can explore this by using rope models and the abstract apparatus of corresponding topological models. Something similar might be possible for developmental biology. > On Mar 17, 2016, at 2:45 AM, Dr. Plamen L.
