The underlying sense of form in my work has been the system of the Universe, or part thereof. For that is a rather large model to work from.

The trouble with a lot of artists today is that they have too much technique and equipment. They don't know what to do with it all. If you cut down on it, you can work more strongly within narrower limits.

To most people who look at a mobile, it's no more than a series of flat objects that move. To a few, though, it may be poetry.

To an engineer, good enough means perfect. With an artist, there's no such thing as perfect.

I love red so much, I almost want to paint everything red.

The first inspiration I ever had was the cosmos, the planetary system.

Why must art be static? You look at an abstraction, sculptured or painted, an entirely exciting arrangement of planes, spheres, nuclei, entirely without meaning. It would be perfect but it is always still. The next step in sculpture is motion.
