    When speaking of global phenomena, I like to look at the "big
picture," as it were.  And the big picture is that the object most of us
here would recognize as most similar to planet earth is a ball of solder
with a scum of rosin remains and dust floating on the surface.  Make the
molten part liquid iron, and the scum granite, and you have an accurate
(within engineering tolerances) scale model of the planet.  Float it in
vacuum for a few billion years, and see what develops.

    Okay...  It's good to know you are back -- some of the most recent
deliveries of dwarfs had some samples that were out-of-tolerance.
