Was discussing about physics, relativity, quantum, etc… with a colleague after a few beer and he told me “a model is just a model, it’s not the reality.”
Mind blowing moment. I’ve always considered the physics we learned at school was a description of reality, but no. It will always be just an approximation.
Well yes. A model is just describes reality, the tools used in the description govern how accurate the model is.
e.g. the speedo in your car, is a model of reality. Obviously it only models a very tiny part, but depending on the quality of the tool; it is more or less describing reality covered by the model.

this. that’s why a model is as good as its known margin of error and limits
and it’s important to remember models work well outside of edge cases ; in your speedometer example, if you brake on ice and your car drifts out of control, the speedometer will show no speed, when you’ll probably have one … but in most cases, it’s a good enough model

No way this wasn’t intentional.
Speedo, Very tiny part, quality of the tool…
I’ll accept it
