I will make one last effort to to set the record straight. In volume
II of the Feynman Lectures on Physics, the title of chapter 15,
section 6 is "What is true for statics is false for dynamics". The
5th paragraph of that section states "Gauss' law, [eq omitted]
remains...". Also in that section, he has a table (Table 15-1) that
contains two columns:

FALSE IN GENERAL | TRUE ALWAYS
(true only for statics) |
------------------------------------------------------
Coulomb's Law | Gauss' law
[...] | [...]

Then in chapter 18, section 1 paragraph 3 you will find the statement:

"In dynamic as well as static fields, Gauss' law is always valid".

I do not think I can make it any more clear than this.

thank you for not continuing to prolong the misinformation in this
thread.


Do you also accuse Feynman of spreading misinformation? Unfortunately
he died a few years ago.

I thank you for your input and continued attempts to overcome the
barriers placed before you. I don't know what Country you come from
but I apologise that the baggage associated with me was then dumped
upon you and I fully understand your action of withdrawal.
Thanks again for your efforts and I trust that you will not see
this as sign of a new America emerging. It is certainly not the
America I envisaged some forty years ago when I arrived. I think it is
best that I to withdraw . Sometime it takes a hundred years
before science is permitted to move on. A similar thing happened to
George Green of Nottingham U.K. and only reemerged in full by the
presentation by some body else who received the acreditation.
