Statement

Ralf: My motivation as an artist comes from the wonder I feel travelling the world of science and technology. I am fascinated with visualizing signals, and using autonomous systems to draw and create. In previous artwork I used laser-projected phase plots of Lissajous-like waves onto cyanotype photosensitive paper. Loe: My motivation is to explore mathematical art, often coupled to innovation in fashion. I like to use advanced techniques such as coding, laser cutting and electronics. This year's art work is a cooperation with Ralph with whom I share an interest in the history of (radio) technology. I work in Fashion Tech Farm and TU/e in Eindhoven and in studio LAURENTIUS LAB. in Sittard.

This art work celebrates Balthasar Van der Pol’s equation, a significant contribution to mathematics developed in Eindhoven a century ago. We designed a device, very much like Van der Pol did a hundred years ago. The heart of the circuit is a vacuum tube which oscillates at 440 Hz in a wave form described by the Van der Pol equation. The 1930's vacuum tube sticks out, whereas the transformers, capacitors and power supplies are hidden in the box. An oscilloscope shows the well-known phase diagram of the equation's solution.
