Quantum Game of Life

by Carlos Pedro Gonçalves

The following are pictures of a simulation of a quantum game of life, implemented in Netlogo:

Initial Configuration

After a Few Steps

Each cell (patch) can be in a vacuum state, or it can become punctured by a qubit state. In the pictures the black cells correspond to the vacuum states that may potentially become occupied by a qubit state, while the white cells have become occupied (in act) by a qubit state.

Quantum information is, thus, created and annihilated out of an information vacuum. A clustered patchworked dynamic geometry emerges, in the current simulation, from local connectivity rules that make it more probable for clustering to occur.

Defining Complexity

by Maria Odete Madeira

Diversity and complexity are contextually (co)implicated , depending, the nature of each, from the nature of the context, in which they are rooted and upon which they systemically depend. This means that to refer the term complexity to a single definition would be not only impoverishing but also difficult in terms of a desirable explicative rigor.

To speak of complexity one must comprehend complexity, itself. To comprehend comes from the Latin cum+prehender that means to apprehend conjointly, thus, the term “comprehend” folds, it its own definition, the diversity that allows one to design it also as complex, in the sense in which it folds in the same act of comprehension, successive resendings between different individuals, or subjects, which implies an explicare and, thus, an unfolding of the subjectivity in intersubjectivity.

Any attempt to define complexity will have to consider, in the act itself of defining complexity, the complexity implicated in the act of comprehension, necessary to that definition.

Comprehending complexity systemically depends upon individuals, groups, species, cultures, societies and civilizations, in their differences, multiplicities and diversities.
