This is a recurring theme in many science endeavors. I remember a story told by prof Mark Krasnoselski (RIP). "Here is a linear dynamic system with a simple positive lookback. It converts an input x(t) into x(t-T). Think about it: it predicts the future! When this has been discovered many "hands-on" people rushed to make actual implementations! Than he paused.... Do you understand the difference between the model and reality?" Received on Thu May 20 2010 - 03:54:45 CEST
