> When, where is the outrage when describing 'voltage' as a type of 'water pressure in a hose'. As you say, it is only accurate to a degree. I was a bit sloppy in distinguishing model and analogy. I guess I meant physical analogy like pressure/voltage (which does outrage me!) vs model being an abstract description of the phenomenon built from the ground up, and was thinking in the context of physics or engineering. The problem with the "bad" kind of analogies/models is they come with a list of conditions under which they don't apply, which is huge and usually not specified at all. For the "good" kind (Ohm's law/etc.), they come with a list of conditions under which they do apply which is finite and explicitly stated along with the equations so you can actually know if the model correctly describes a particular case.
