In the 1960s the author sought to rethink the basic concepts of sculpture-space, matter, gravity and light-by studying the theories of relativity and quantum physics, the connection of space to time and matter to energy, and the relationship of all these to gravity. Subsequently, trying to understand the fundamental forms in nature, she discovered a continuity underlying them: Spirals are not only forms of growth or turbulence, but are also the link between spheres (forms of balance and minimum volume/energy) and waves (forms of energy/motion). Flow phenomena shaped the new style of her landscape sculptures, which are expressions of fluid dynamics and other nonlinear processes.
