To what extent can I use the concept of "God" in a meteorology lecture without offending anyone? In about a week I'll be introducing the Coriolis effect to a group of about 50 undergrads.  This means I'm going to have to at least touch on fictitious forces and frames of reference.

These aren't physicists and I can't guarantee that they've taken (or paid attention during) elementary physics, so I can't just put the equations up on the board and get comprehension; I'm going to have to be a bit more visceral.

My strongest example refers, from time to time, to the inertial frame as the "God's eye view".  This means that while working through it, I would be using the word "God" a few dozen times during lecture.

I don't personally find this term offensive but I don't want the presentation to turn my students away from the content.

So my question has two parts:


Is using "God" in the way that I've detailed acceptable, or should I search for a different example?
If it is acceptable, should I have a heads-up at the beginning of lecture?




Extra information:


I'm an adjunct at a large public university in the United States.
This is an introduction to applied meteorology course.
I've been teaching for six years but this is only my second time teaching this course.
It's acceptable, but why do you need to use it? It seems to me that you could just as easily use a secular phrase like "looking down from above"?
