That's a canard..


it was originally intended to demonstrate that simple models do not 
always work (e.g. flapping wings are not steady state flow, no you can't 
neglect thermodynamics, etc.)


Sort of like modeling an antenna as a lumped RLC.  Works for small 
frequency ranges, but not for large ones.
