Picking Flowers

I was trying to look up the exact quote "Pick a flower on earth and you move the farthest star," which I thought was James C. Maxwell. Turns out it was Paul Dirac. Not sure why I had them confused! It is still one of my favorite physic's quotes. Found the reference in the online version of the book Newtonian Physics by Benjamin Crowell (under the section heading for 10.4 Vector Addition of Gravitational Forces). I love physics!
