he is a yo-yo.

candidly, when I first saw his post and noted his email address, I figured some
yo-yo hijacked his address. He claimed professional expertise in fluid flow,
but his website make no mention of such, though it does promote his "expertise"
in control systems for things such as MRI's.

similar to what the good professor at MIT observed with
his fan.

what the "good professor at MIT observed" was that starting
with an an empty
tube there was a tiny movement until the tube filled.


I seem to remember you damned the professor for using a metaphor
. . .
