Meter sticks laid out around the rim of a rotating disk will foreshorten by the Lorentz factor. This means more of them will fit around the disk in the reference frame of an observer on the moving rim. Q: In physics, what name is given to the longer measured length by a foreshortened meter stick? I've already thought of "proper distance" and "relativistic distance" but these may not be acceptable. Of course there is always "wrong distance"...but that would imply there is a "wrong time" too.
