Gauss' Law is for static electric charges and fields.

It is usually used for problems in electrostatics, but it is not
confined to such problems. The differential form of it is just one of
the Maxwell equations:

div E(x,t) = 4\pi\rho(x,t)

Integrate it over a fixed surface and you get the integral form, which
is Gauss's law. It is valid with time-dependent charge densities and
time-dependent electric fields.

John, you have hit it on the nose. It is the logic that is important
and that logic applies for a resonant array in situ
inside a closed border whether time is variant or otherwise.
The importantant point of the underlying logic that all inside the
arbitary border must be in equilibrium at the cessation of time
because the issue is not the static particles but of the flux. Period
Thus the very reason for a conservative field in that
it is able to project static particles in terms of time if time was
added. For static particles time is not involved therefore
ALL vectors are of ZERO length and direction is an asumption based on
the action if and when time is added.
John, you included time but did not mention time variant, was this for
a reason? I have specifically use time variance since that enclosed
within the border is an array in equilibrium
from which the conservative field is drawn from.
I am so pleased that some one came along that concentrated on the
logic and not the retoric and abuse.

he may have hit what you believe correctly.. but unfortunately it is not a
valid generalization. as i stated in my other message:

no, i'm afraid you can't just put a 't' on each side and have it make sense
in the general case. time varying charge implies a current, a current
implies a magnetic field, then you have to include Ampere's law and add
curl(E)=-dB/dt to the mix. while you may be able to constrain the changes
in rho(t) to some short time or constant current and eliminate the dB/dt
part of the problem, that would only apply in specific conditions, not to
the general case.- Hide quoted text -

Thats O.K. David,
The appeal made for this thread was for people outside of America
since eamericans were more interested in other things and I am
assuming the Gentleman is from outside America. This discussion in the
past has been bedeviled with arraogance and abuse to the neglect of
logic, this has been the mode of this group for a very long time. If
there was not such derision you could have looked up Gaussian law on
the web where you would have found the mathematics behind the logic.
If you had done this you would have found that curl is a part of the
mathematical underpinning that in the event of time that part of the
equation is zero. If time was part o0f the logic then you insert the
value of curl in the equation, look up curl for your self and place it
in the original equation which you are not changing i.e. concentrate
on the mathematics and the underlying logic and the result becomes
apparent.( and I have stated as such in past threads)
This has been there for more than a hundred years so don't be
disappointed that you and others did not realise the significance.
It was my mathematical interest in antennas and circumstances that led
me to this discovery but now the door is open we can all have the
enjoyment of the paths that it reveals.
John, what is your call and where are you from? You are to be
congratulated for delving into logic without being sidetracked by
others. I was just at the point of giving up and to wait for my patent
application to be printed some time.

Art XG
