As to simple terms, I assume you are talking about a conceptual model. The problem with a conceptual model really is that we have only a few conceptual native schema to work with. I.E. As we grow up and observe the world, we don't seem to need more than about twenty five. (See George Lakoff's work) We deal with the world of macro-effects, so none of them have the desired qualities of having a super-positional state that resolves when we observe it. If you are talking about a mathematical model, I think they tend to be even more abstract, and definitely not intuitive until you spend a lot of time with them.
