notes: label: Description
content: Crockett Johnson based this painting on the discussion of motion along inclined planes by Galileo Galilee in his <I>Dialogues Concerning Two New Sciences</I> (1638). Here Galileo showed that if from a fixed point straight lines be extended indefinitely downwards and a point be imagined to move along each line at a constant speed, all starting from the fixed point at the same time and moving with equal speeds, the locus of the moving points will be an expanding circle.
label: Description
content: This painting shows four superimposed circles in various shades of gray, white and black. These circles all have a common point at the center top, and differ in radius. They are shaded into several regions which are divided by lines originating at the common point. The work has an orange background and a black wooden frame. It is probably based on a drawing in E. G. Valens, <I>The Attractive Universe</I> (1969). This volume is in Crockett Johnson's library, annotated on the page indicated.
