Are models always right?
Are models always right? All models are approximations. Assumptions, whether implied or clearly stated, are never exactly true. All models are wrong, but some models are useful. Why do we need to model a physical system? In order to develop new concepts into prototypes and ultimately into products, physical system modeling is virtually a necessity. […]
