      1. Good day

        The size of the cosmos
        is approximate in numbers
        understandable and tangible

        Its content
        will be

        since the beginning
        of the universe
        until its end

        remains to man
        down to the last
        despite all teaching
        the knowledge
        the research
        a secret

        The life
        and things
        I think so
        are indivisible
        connected with each other

        Best regards
        Hans Gamma
