Info-autopoiesis or the self-referenced, recursive, interactive process of information self-production that engages all living beings in their efforts to satisfy their physiological and/or relational needs relies on Bateson's difference which makes a difference.

Information is not a fundamental quantity of the Universe. However, in denying the fundamental nature of information, we assert its importance for living beings in their environment. Living beings use their sensory organs to discover the non-living and those living in their environment. Through their sensory organs, they discover the bountifulness...

Information ethics (IE) is a field of fundamental and applied study that lacks the firm foundation of a definition of information. The at times ethereal, at times pervasive nature of information contributes to the elusiveness of a definition. Paradoxically, everyone seems to recognise information when they see it, but there is great difficulty in a...

The (Immanence of the) Information Process and the Labour Process in the Information Age
Article
Full-text available
Gregory Bateson is well known for defining information by stating “In fact what we mean by information – the elementary unit of information – is a difference which makes a difference…” This conceptual perspective has the merit of simplicity and generality. Simplicity, in addressing the complexity of information. Generality, in seeking applicability...

Nuclear-grade Zircaloy-4(R) tubes are produced by a unique manufacturing process known as pilgering, which leaves the material in a work-hardened state containing a pattern of residual stresses. Moreover, such tubes exhibit elastic anisotropy as a result of the pilgering process. Therefore, standard equations originally proposed by Sachs (Z Met Kd,...
