But they can pare all that down to something expressed in terms people are familiar with. And that has the bonus purpose of helping them understand why the familiar terms were familiar: the "correction factor" is small under circumstances we encounter, and only becomes large under circumstances we rarely do.
If that intrigues somebody enough to learn the actual physics, they'll encounter a completely different and more-encompassing formulation which looks not at all like overfitting. One that turns out to be more elegant, in fact, cramming more information into less notation. But it's information nobody needs until they're doing fairly advanced physics, so we're not going to be teaching it in elementary school any time soon.
