finding of a state of light: distribution of luminous intensity and its fluctuation
2000 Jan-Mar : Exhibition, "Sound Art - Sound as Media" at ICC (NTT Inter Communication Center) , Tokyo

Light is a fascinating phenomenon, but understanding its essence is extraordinarily difficult. Unlike wave/vibration phenomena propagated through material media, as an inherency of space-time itself light has the disposition of electromagnetic wave which can propagate even through a vacuum [*1] and at the same time has the disposition of photon particles which can hold localizable energy and momentum. The complementarity of light's dual disposition as wave and particle has made it a research topic of continued interest and thinking about the essence of light gives rise to a wide manifold concept. "Light" is also one of the most familiar of physical phenomena. By illuminating the spaces we inhabit, light is an indispensable element in the structure of cognitive perception known as vision whereby we are able to distinguish objects. In this work I have dealt with this familiar "light" that gives rise to such conceptual manifoldness in relation to the "place" on which it illuminates.
Lighting as a function to illuminate spaces is a kind of apparatus built into a place in order either to light up the entire place uniformly or to highlight one characteristic part. I regard the apparatus as a kind of under-structure which forms a property of the place. In other words this property which is some state of physical, epistemological, organizational under-structure must continue to operate in the "place" where is defined as "a closed finite range in space-time", in order for the place to maintain its integrity[*2]. Lighting as a such an apparatus primarily provides information useful for the visual perception of space. And when we consider the functions attributed to that place, our own activities as we enter into it are greatly involved in this illuminated space. Moreover, even the lighting that appears to illuminate the space uniformly, if seen as a space-time phenomenon can also be recognized as a fluctuating light source turning on and off in 50 cycles per second or more. Normally, however, we are not aware of these cycles. It is for this reason that I believe that focusing on the luminous fluctuations and distribution of the light source is an extremely useful way of understanding "place" and its "property".
In this project I have been able to find several characteristic distributions of light as regards a property of the place at ICC. In "finding of a state of light: distribution of luminous intensity and its fluctuation" I have treated those states in term of the movement of objects. The phenomena that will be visible/audible here are one in which "light" propagating as an inherency of space-time goes through an energy exchange using the contact potential difference occurring between the two distinct materials within a solar cell to be translated into the dynamic movement of speakers' cone paper. Thus the distribution of light and its fluctuations found as proper to a specific place are rendered perceivable as the movement of an object without the addition of any energy from the outside. Through this movement made perceivable I attempt to reflect once again on the relationship between the state of light that we experience on a daily basis and the "places" that the light illuminates. And in the process, I hope to imagine the emergence of a world distributed by the manifold concept of "light".

*1- There is a tendency to conflate the material wave/vibration phenomena as "sound" with the electromagnetic wave phenomenon as "light", but the two are fundamentally different. The only characteristic they have in common is the periodicity of movement found in the partial differential form of the wave-equation formula.
