Today I was arguing with my friend about DNN. I was not a big fan of DNN. Somehow our conversation drifted to chaotic systems (he insisted DNN was one :-< ).
This argument led me to google & read about dynamics and chaos and I found it soooo cool! For example, this famous Lorenz system. It has so many strange and interesting properties, like strange attractor is actually a fractal with dimension ~2.05. And I realized that the chaotic system exhibits in Exploratorium I saw a couple of years back is just a Lorenz system (initially emerged from a study of convection rolls in the atmosphere). Also read a little about bifurcations. Somehow reminds me of the index theorem in differential geometry. ???@@
