Domain walls ...

"A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls are also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model or models with polynomial potentials.^[1][2][3] Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is a false vacuum.

A domain (hyper volume) is extended in three spatial dimensions and one time dimension. A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension.

Important examples are:

• Domain wall (magnetism), an interface separating magnetic domains
• Domain wall (optics), for domain walls in optics
• Domain wall (string theory), a theoretical 2-dimensional singularity."

a space to tell stories of and compare walls seek openings so many spaces of / to welcome	these walls: are they necessary? whose needs do they meet? we know walls listen and talk too who do they protect? who do the respect?

Among the domain walls
are those that bring us together,
those that bring us - 'I' into being,
and yes, those that [try to] take us apart.

Hodges' model: Background - Foreground and the Space Between

If there is one thing that h2cm exemplifies it is distance.
It is after all a four-way signpost.
Seven-way (and more) if we include past, now and future
and wrap these in a spiritual domain.

The novice coming to study and explore the periplus (Cunliffe, 2001) that is health and social care (plus informatics), is presented with a daunting and yet exciting coastline.

The curriculum the new learner must navigate ('negotiate' literally via learning contracts) lies before them the challenge heightened by several vanishing points on several horizons.

Our senses are designed to quantify and our intellect to qualify this thing we call distance. Distance within conceptual spaces and the semantic web is all about semantics: the meaning of the terms we use in everyday and specialised languages.

If it is not a case of begging the question, consider the key concepts that comprise an explanation of h2cm.

Declare one concept, for example, ‘individual’ and we create a semantic singularity (in the sense of conceptual plurality not noun?). As soon as we add another concept, such as 'group' a conceptual space (the h2cm grid or matrix) is created.

The axes of h2cm are not passive.
They provide a spatial and cognitive scaffold.
Like gravity each concept is related to others by an all pervasive force.

The force here while not physical, it is universal in the sense that every concept is associated with the others by virtue of their similarity. Even if not physical in that arc of the diver sense, this similarity can be calculated and can be represented computationally within a computer program or virtual reality environment – the force potentially represented as feedback.
