I can't begin to capture the whole metadiscussion, which spans
several subjects and 2 (or more?) newsgroups, but at least
I can quote the part where John posted the puzzle:
Quoting from John Larkin's post, 7/10/2010 at 11:16 AM
on SED. Subject: Win Hill: Inverse Marx Generator ??
To celebrate the 21st century, I have composed a new riddle:
Start with a 4 farad cap charged to 0.5 volts. Q = 2 coulombs.
Carefully saw it in half, without discharging it, such as to have two
caps, each 2 farads, each charged to 0.5 volts. The total charge of
the two caps remains 2 coulombs, whether you connect them in parallel
or consider them separately.
Now stack them in series. The result is a 1F cap charged to 1 volt.
That has a charge of 1 coulomb. Where did the other coulomb go?
I think this is a better riddle.

No riddle at all for anyone who even doodles a single picture (after
reading the Wiki Conservation of Charge Page)
