Leonardo

The author links developments in modern physics with the perception of movement in sculpture. Particularly by tracing implications of Einstein’s paper on the Theory of Special Relativity, the sculptor shows changes in a variety of twentieth-century art forms and in his own recent work. His current roadway installations, composed of elements arranged in a series and covered with reflective sheeting, make use of the dimension of time. Such installations depend on movement by viewers and changes in light in order to be perceived. He concludes with observations on the sources of change in art and on some unusual sources of change in his own career.
