The sad thing about Gerald, as I remember vividly from his last r.a.sf.w
crossover several years back? Is that he honestly is -unable- to see that
both the walking person, and the car taking the roundabout, turn all the way
around once, for each time they go around. Explanations wash over him and leave
him dry; he absorbs nothing, but just keeps stating things that mean exactly
the opposite of what he's trying to mean.
[For anyone who's NOT Gerald - GK, stop reading here, it'll only get you mad
again - think about what the person walking around & pointing, that way, sees,
and what the car's driver sees through the windshield. Each of them has their
gaze go across the surrounding scenery, all the way around, once, each time
they walk/drive around; relative to the object/the center of the roundabout,
they always show the same side. Relative to the background, which is what's
relevant here, they turn around exactly once. GK can't make the connection
that there's two different frames of reference here, and can't see that "how
often it turns in the rotating frame [*]" is different from "how often it turns
in the fixed-background frame" ... and waves away any effort, no matter how
simple, to get it into his head, because he Knows He's Right.]
Dave, this synopsis may save several of you hours of alas-futile typing
[*] the one moving along with the car/person AND moving so as to keep their
face pointing the same way relative to that frame
