A good vehicle can be a non-technical character to whom the technical character provides a brief -- not disrupting flow -- and particularly lucid explanation.

You will need a fairly exceptional consultant for the brief and lucid explanation.

Your job, as the screenwriter, is to fit that explanation into the screenplay in a manner that seems natural and furtherw the storytelling.

Then, you get an audience that learns a bit, and experts who say to themselves, "Hey, they actually got that bit right." (Maybe they're even quietly impressed at that. And when their friends ask them what movie gets "X" right, they're more likely to cite yours.)
