Yes, it does. Or, rather, it doesn't. Depends on one's context. Mine is clear. Look, it is possible to have a discussion in which you insistently spell out pages and pages of equations describing the physics of light itself, optics, thermodynamics, as well as diverse aspects of physical and electrical engineering requiring all the more math, and at no point in that particular discussion would it be untrue that you are describing the projection of a movie onto the screen. How is this difficult? Are you describing the physics of daisy farts? Okay, you know that trope about scientists being elitist and uncommunicative? And you're aware, I presume, that mythopoeic elements generally orbit some assertion of perceived truth? Yeah, this is an example of how that trope happens. Is it really so hard to acknowledge what that math describes?
