Non-knowledge in Verne is the unknown that one must venture into in order to constitute knowledge. The unknown is composed of worlds for which there would be as yet no concept or language. With Zola and Turner, the principle of stochastics is illustrated by their artistic endeavour in presenting steam, smoke, water and a variety of indeterminate phenomena. For science is a system, just as poetry is a system. Rain, sun, ice, steam, fire, turbulence - they all engender chance effects.
Modern physics begins here with the realization that turbulence prevents the implosion of systems.
Noise is a joker necessary to the system. It can take on any value, and is thus unpredictable so that the system is never stable. Instead, it is non-knowledge. Systems work because they do not work. Dysfunctioning remains essential for functioning.
