A few more quotes, then I'll leave it alone. Thanks for your indulgence! "There are sadistic scientists who hurry to hunt down errors instead of establishing the truth." --Marie Curie "Science is a wonderful thing if one does not have to earn one's living at it." --Albert Einstein "Our planet doesn't seem to be the result of anything very special." --Murray Gell-Mann "In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time someting like that happened in politics or religion." --Carl Sagan
