Document Summary
Eae1022 lecture 27 - earth, atmosphere and environment. Simplified representation of a complex process, system or object that cannot be experienced directly. Is not supposed to be a perfect representation (by definition) Is full of assumptions, sometimes overly simplified depending on the problem: complexity of model depends on your application. What is a model: models do (cid:374)ot pro(cid:448)ide (cid:858)truth(cid:859), (cid:373)erel(cid:455) a(cid:374) idealised represe(cid:374)tatio(cid:374). (cid:862) there is no need to ask the question "is the model true?". The only question of interest is "is the model illu(cid:373)i(cid:374)ati(cid:374)g a(cid:374)d useful?". (cid:863) george box, 1978: models generally provide representations of the stable parts of a system. Why do we use models in eae: understanding, for revealing how our world works where direct observation and controlled experimentation are not possible, prediction. Present environmental states that are not easily measured or observed (e. g. location of mineral resources: future environmental states (e. g. weather forecasts)
