¡THE GOAT A THE GOAT! 🐐

Movie geniuses write math on windows because a chalkboard would put the actor's back to the camera.
Directors need to film a face while it thinks. Glass is the only writing surface you can shoot through, so the camera sits on the far side and holds the equations and the actor's eyes in the same frame. The whole cliché is a camera solution dressed up as a personality trait.
The production behind it gets better the closer you look. For A Beautiful Mind, the studio hired Dave Bayer, a Columbia math professor, as Russell Crowe's hand double. Every close-up of writing on that dorm window is a real mathematician's hand, and Bayer pulled the equations straight from Nash's actual papers.
One of those papers caused a small civil war among mathematicians. Nash had deliberately used every Greek letter in it, including π as an ordinary probability variable, and Bayer copied it faithfully. A widely circulated publicity still ended up showing Crowe staring at "0 < π < 1" while half the math world debated whether the consultant was trying to make him look bad.
And the reason you never see this in real life is the same reason it works on screen. Writing on glass is legible from exactly one side. In a movie, that side has a camera on it. In your office, it has your confused coworkers.
The equations on the glass are real Nash. Only the glass is Hollywood.
