Well, after reading the above post yesterday morning I thought I'd wait
untill the inevitable pandamonium settled.  However, apart from Ben the
silence is deafening.
Should I be surprised at this silence?  I truly don't know if that is the
correct responce.  Undoubtedly a clear indication of lack of experience on
my part.
On a side note, Ben asked in a previous post whether or not using the
negative numbers side in some theoretical works was valid.  And since then
I
have read the following.

Imagine an AM antenna one-fiftieth of a wavelength long, that needs no
radial ground system, occupies a small parcel of land, produces little or
no
RFI (Radio Frequency Interference), has great bandwidth and performs
better
than a full-sized vertical radiator.
Does this sound like a fantasy?
Until recently, it would have been.
Now working models of such an antenna exist in the Middle East and at
NAB99
(National Association of Broadcasters' 1999 Convention in Las Vegas).

The "reversed form" (negative solution) of Maxwell's Fourth Equation,
states
that a magnetic field can be produced without current flowing in a
wire........
On April 19, 1999, at the Las Vegas Convention Center, Brian Steward from
the Department of Engineering at Glasgow Caledonian University presented a
paper on what has been patented as the Crossed-Field Antenna
[/quote]
I found the above very interesting, and have begun to wonder at what else
may be lurking within other negative solutions.
Is a negative power solution not valid? Negative work is still work is it
not?

I've never been able become comfortable with the interpretion of Young's
experiment.  It's an interesting case (apparently) of where the
interpreation has been tailored to fit the result.  A difficult thing to
critisize or question successfully.  You are a brave man Bill!!
Thank you very much,
Highest regards,
Vince
