+| Simplification  | All simulations select certain parts to be included and some parts to be excluded (no complete simulation exists of any natural phenomenon -- it couldn't, because everything in the world can (potentially) affect anything else). \\ "...simplifications, or abstractions, are a necessary part of the modeling of nature. Without them, the models would mimic reality instead of explaining it." \\ — Przemyslaw Prusinkiewicz  |

 | Define processes  | What are the operations we want to manipulate the parameters? What are their inputs and outputs?  |
