Is there a word or common phrase that means "I know this isn't strictly speaking correct, but beginners should use it as a working model until they are more proficient and then we can discuss why the model isn't quite correct"
Some examples of the concept might be:
- "An object in free fall will accelerate at 9.8 m/s^2" (only true in a vaccum - experts will recognise that air resistance is a factor, but ok as a working model where you don't need to be more precise)
- "a computer has a fixed amount of memory" (useful for a beginner, not true because of virtual memory)
- "in music, a crotchet is always longer than a quaver" (useful for a beginner, not true for an expert due to changes in tempo or pauses etc)
I'm asking because I'm writing technical content - my audience tend to be pedantic about detail, so I can either say "this is a working model etc" at the top (possibly taking time to define the phrase first), or pepper my writing with "this is only true as long as you don't consider xyz" which tends to make it overly verbose and harder to read for a true beginner who won't have any idea about the hidden complexities yet.
Note that I've tagged as single-word-request or phrase-request because the answer could be either, for example I'd like to be able to say "For the purposes of this document, I'm going to use a XXX model to make my writing clearer - experts will recognise that there are things that are not quite right, but that are nonetheless useful to understand the concept"
