    | Phil said there was a "lack of interest" on the part of the authors "to
    | explore the field of fast rise time pulses and edge transitions".

    They don't seem to have that interest. It could be because these kinds of
    surges happen less often. It takes a close lightning strike for it to happen.


    | Of IEEE standards for characterizing surges Phil said "they've missed a
    | lot of reality."

    They are at least not covering all of it. It's not practical to cover it all
    in one document.


    | Of an experiment by Francois Martzloff, an expert in the field, that
    | directly contradicts Phil, Phil says "then he flubbed the experiment."

    This comment was pointed at Bud, who misunderstand the science behind any of
    this. I don't believe Martzloff flubbed anything. Instead, he just did not
    focus on it. Bud misunderstands this. Bud assumes ONE document is complete
    coverage of all science.


    | Of Martzloffs comments, quoted earlier, for raising clamp voltages Phil
    | said Martzloff had a "hidden agenda".

    Again, this is for Bud's benefit so maybe it would spur him to think about
    what he reads instead of just spouting off misapplied science. I was hoping
    he would be able to learn. This was a while back. He's show no learning
    since then, which suggests he might be full.

    | Phil lives in a tiny fantasy world, where he is the only one who
    | knows anything.

    Michael A. Terrell is one of those people that contributes absolutely NOTHING
    when he faces someone he doesn't like, or who says things he doesn't like.
    Mr. Terrell does have knowledge of science, technology and engineering. But
    he is a bitter person, possibly due to the health conditions he faces, or maybe
    due to some bad experiences in life. He has become antisocial and prefers to
    make personal attacks on people instead of conducting discussion on a point by
    point basis. He could discuss, and in many cases he does. But when he has the
    opportunity to make personal attacks, it's like he switches personality.

    Google Groups can show you his past posts. Judge for yourself.

    | Anyone interested can google for "phil's phantasy physics".

    And then they can compare that to real physics, and if the understand what
    they read, they can see the fantasy is in Bud's head.
