Zero is an extraordinary number. It is a number that denotes the existence of absence. As soon as humans acquired consciousness, they began to count: one sheep, two sheep, three sheep; one apple, two apples, three apples. And voila, the discovery of natural numbers! (Apparently primitive numbers only went as far as ten, because humans have ten fingers with which to count, hence the decimal system.) Natural numbers were based on our practical sensations of counting. But at some point, the formulation of the concept of zero by an Indian mathematician fundamentally changed human consciousness. High-speed calculations of the 0s and 1s of the binary numeral system underpin the basic principles of the computers that sustain our modern civilization.

As an artist, I wanted to give zero a shape. To make zero – which has no physical existence – visible, I decided to craft an object that went right to the very brink of zero. I sought to give physical form to a three-dimensional mathematical function, the equation for which becomes zero at its zenith. I made a mathematical model in two parts, an upper and a lower, of which the upper is suspended in the air. Using stainless steel, I was able to craft a shape that tapers to a point just 0.8 millimeters wide. The zero point is found about one centimeter beyond that. It definitely exists and its position can be shown; it just happens to be invisible.

The realm of zero lies in that narrow interstice where the two points confront one another here in this eighteenth-century chapel at Ama, where the mathematical model has taken up its discreet residence. I invite you to carefully examine that invisible point, for in it can be found the mystery of existence.
