Steve S.,
You and I are the only two participants in that discussion to have presented
any empirical evidence. In the spirit of experimental collegiality, would
you try my experiment, and report back to me. Fill a basin with water Set
it to spinning in a concerted way. Be careful not to
Nick and all,
If the following comment has already been made (and disposed of),
please accept my apologies (the house was full of visitors for a
while and I stopped keeping up with my mail).
One thing that leaps to my eye in the description of the
empirical experiment made by Nick, and
Lee,
Yep! There is that little grid in the mouth of the drain and the little
tornado thingy generally forms on the hole at the center of that grid.
Doesn't explain why the water leaving the drain starts to slow down when the
natural vortex forms, by comparison with the circumstance in which I
Are you asking why does a vortex form at all?
No.
Are you assuming that the
drain is rifled in some sense and that a vortex wouldn't form without the
rifling.
No, that hadn't occurred to me, and I don't think
(having done my share of household-level plumbing)
that drains are rifled in
I was amazed to learn that gedanken experiments involve so much depth. I had
thought thought experiments were just simple tests that it would be VERY nice
to do, but for various reasons could not be executed. Like having all
gedanken foolosofers leap from high buildings (under humane and
But peter. I actually did an experiment. So, your criticism has to shift from
calling me an air head to calling my experiment dumb … and,, presumably, having
reasons why it’s dumb.

Nick, Peter -
It is good to see the curmudgeons with their curmudgeons out. Maybe we
can get Doug to flail (swirl?) his too! grin and I think we have a few
others here as well...
Meanwhile, we are having a soiree tonight that I invite you (all) to, to
celebrate the rain falling on the fire
Hello All,
Years ago I ran some funky little tests spinning liquid epoxy on a platter
to attempt perfect parabolas.
The equations required angular velocity and viscosity to get the correct
equation for curvature.
If your sink is analogous then the swirling motion should leave the water
near
Hello all-
I am following this thread with interest because of similarities
between gedanken experiments and the classic creative processes: an
idea, whether potential scientific theory or potential visual/
multimedia theory is clarified, then attempted in the mind, possible /
probable
Be there within the hour. Want anything? TJ's is on the way.

Vladimyr,
I love it! I am going on a trip, so unless my host is particularly
forgiving, fear that I wont be able to try it at his house, but I sure will
when I get back. Contrary to Lee, I don't think, however, that confined
water has anything to do with it. Plumbing systems have pressure
