ABSTRACT
The prototyping of science instruments plays an essential role in forming the modern public sphere engaged in future-making. It defines the public expectations about science and technology as not only a matter of personal and social agency but also a transpersonal and metaphysical teleology. The liminal and experimental environments then play an essential role to overcome the reduction of instruments to means of labor and to use them as prototypes for action or leisure. The chapter discusses the influence of philosophy, religion, politics, and business on the development of science instruments and how they have transformed into infrastructures and governance machines.
