This is an
interesting electrical engineering article on the discovery of a new
gizmo that I thought I'd share.
hold-up over the last 37 years, according to professor Chua, has been a
misconception that has pervaded electronic circuit theory. That
> is that the fundamental relationship
in passive circuitry is between voltage and charge. What the researchers contend is that the
is actually between changes-in-voltage, or flux, and charge. Such
is the insight that enabled HP to
invent the memristor, according to Chua and Williams.
"Electronic theorists have been using
the wrong pair of variables all these years--voltage and charge. The missing
part of electronic theory was that the

and charge," said Chua.
The situation is analogous to what is called
"Aristotle's Law of Motion,
which was wrong,

must be proportional to velocity. That misled people for 2000 years until Newton
came along and pointed out that Aristotle was

Newton said that force is proportional to acceleration--the change in
