This week's PCT quiz:
"The Queen took a large spoonful of soup and displayed her fine person
and graceful manner, in alternately looking at the company in various
parts of the hall and ordering several kinds of seasoning to be brought
to her, by which she fitted her supper to her taste. When this was
accomplished, her Majesty exhibited to the admiring spectators the
magnificent spectacle of a great queen swallowing her royal supper in a
single spoonful, all at once. This was all performed like perfect
clockwork, not a feature of her face, nor a motion of any part of her
person, especially her arm and her hand could be criticized as out of
order."Who was the Queen?
Who wrote this encomium?Ted

My finger points here: "Now imagine having to do it in reverse:
without looking at the shade, you must choreograph the sequence of
twists around each joint that would send the shade along a straight
path."The error is the idea that the "frightfully complicated" trigonometry
is what is controlled, and that this occurs "without looking at the
shade." Instead, (the position of) the shade *is* looked at. Indeed,
it's the primary thing under control. The other angles are not
(individually) controlled, as would be seen by the way modest
interferences with any given joint would be compensated for by the
action of the arm as a whole.Tracy

That's exactly what I had in mind.
Ted
I tripped and fell on the sidewalk last Friday; suddenly found myself
running, trying to get my feet under me, failing, and sprawling more or less
face down.
Apparently I used my left hand and arm to break my fall. A few hours later,
reaching for something, I felt serious discomfort in my shoulder (rotator
cuff, probably).
As I repeated the reach several times, however, I could almost feel the
low-level control systems reorganizing, although I noticed no difference in
the trajectory of my hand or the angles of my elbow, shoulder, or wrist.
After three or four iterations, I could do the reach without discomfort.
PCT at work.
Greets.
