I think you're going too far with this. Most people understand scientific theories to be an approximation. F=ma is approximately true, in the sense that it's only accurate within the newtonian regime and each of those terms includes so many asterisks that you will only ever measure it approximately.
The latter is the jokes about the physicists "assuming a perfectly spherical cow."
In fact that's kinda the whole point of the "unreasonable effectiveness of mathematics" essay. It is unreasonable that mathematical approximations are so good at describing our world.

- try_the_bass 4mo agoI've definitely heard a similar joke about economists. It probably applies to most sciences, tbh
- nagaiaida 3mo agodo we mathematicians do particularly much work with cows that is made simpler by assuming they're spherical?
- the_af 3mo agoAt the very least the cow-equations are made simpler!
