Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.
George Box

I came across this quote in Angie Bowen's newsletter and it really resonated with what I already believe about models. No one model can 100% correctly describe something while also allowing leeway for edge cases. It's why we're still searching for a unified field theory in physics and, in my opinion, probably always will be. That doesn't mean, however, that a model isn't useful, just because it's not 100% accurate.
