MODELING A description or analogy used to help visualize something that cant be directly observed .
Modeling Methodology Why ? The need for a modelFind ? What do we need to describe the model Given ? Available data Assume ? Assumptions we make How ? The physical case Predict ? Equations, calculations, Answers Valid ? Are the predictions accepted Verified ? will it be useful Improve ? What did I ignore !Use ? What will I use The model for
