* About Modeling "We need explicit or implicit models so as to able to:   
 1. order and generalize about reality;
                                 2. understand causal relationships among phenomena;
                                        3. anticipate and, if we lucky, predict future developments;
                                            4. distinguish what is important from what is unimportant; and
                                            5. show us what paths we should take to achieve our goals."
