  • Re: POSITIVE work in cyclic motion

    Dear subscribers,

    after spending an entire Sunday for writing my latest
    message, I feel it difficult not to react with dismay to some of Craig
    Nevin's statements. Craig didn't understand at all my point.
    He just repeated the same mistakes against which I wrote.

    Are there any other subscribers who want to defend Newton?
    I quit. I feel I have already done more than I should.

    The work done
