Natural Networks.


The 1999 incarnation of
12.517 G(2) 3­0­9 Spring 1999
Simple Models of Complex Physical Systems.


Contacts: Prof. Dan Rothman and Peter Dodds

A twice-weekly meeting to discuss recent advances and develop new ideas in the understanding of networks as they appear in geomorphology, biology and other areas of science.

Interested students should register for 12.517, Simple Models of Complex Physical Systems. The first meeting is scheduled for Tuesday, February 2nd in 54­313 at 11 am. Unless there are conflicts, we will meet thereafter on Tuesdays and Thursday from 11 am to 12:30 pm.
