The following is from the preface:
Question: Which has influenced you more, nature or modern machinery?
Calder: Nature. I haven’t really touched machinery except for a few elementary mechanisms like levers and balances. You see nature and then you try to emulate it. But, of course, when I met Mondrian I went home and tried to paint. The basis of everything for me is the universe. The simplest forms in the universe are the sphere and the circle. I represent them by disks and then I vary them. My whole theory about art is the disparity that exists between form, masses and moments.… Even my triangles and spheres, but they are spheres of a different shape. (1)
