Question: How do you get that subtle balance in your work? You put a disk here and then you put another disk that is a triangle at the other end and … - Alexander Calder

Marcel Duchamp's 'Nude descending the stairs' is the result of the desire for motion. Here he has also eliminated representative form. This avoids the connotation of ideas which would interfere with the success of the main issue - the sense of movement.

What I mean is that the idea of detached bodies floating in space, of different sizes and densities, perhaps of different colors and temperatures, and surrounded and interlarded with wisps of gaseous condition, and some at rest, while others move in peculiar manners, seems to me the ideal source of form.

How can art be realized? Out of volumes, motion, spaces bounded by the great space, the universe. Out of different masses, tight, heavy, middling - indicated by variations of size or color - directional line - vectors which represent speeds, velocities, accelerations, forces, etc...- these directions making between them meaningful angles, and senses, together defining one big conclusion or many. Spaces, volumes, suggested by the smallest means in contrast to their mass, or even including them, juxtaposed, pierced by vectors, crossed by speeds. Nothing at all of this is fixed. Each element able to move, to stir, to oscillate, to come and go in its relationships with the other elements in its universe. It must not be just a fleeting moment but a physical bond between the varying events in life. Not extractions, but abstractions. Abstractions that are like nothing in life except in their manner of reacting.
