Waterfall as Metronome is an ongoing project that documents artificial waterfalls around Midtown, NYC, and explores the role of waterfalls within listening, sonic arts, and urban studies.

Whereas the Newtonians focused on the clock as an appropriate image for the world, chaos theorists are apt to choose the waterfall. The clock is ordered, predictable, regular, and mechanically precise;
the waterfall is turbulent, unpredictable, irregular, and infinitely varying in form. The change is not in how the world actually is-neither clocks nor waterfalls are anything new-but in how it is seen. N. Katherine Hayles, Chaos and Order: Complex Dynamics in Literature

The modern study of chaos began with the creeping realization in the 1960s that quite simple
mathematical equations could model systems every bit as violent as a waterfall. Tiny differences in input could quickly become overwhelming differences in output.
