heterogeneous space

Air exists so harmony. It always reaches to an equilibrium state. However the aircraft wing design proposes to change the status of air: lower pressure on upper wing while higher pressure on lower wing. This differential of air condition make the heavier-than-air aircraft lift up to the sky. This incredible phenomenon makes me think of the heterogeneous quality suggested in the architectural design. Different kinds of air coexist together and establish a relation that gives the lift-up performance. It has always been discussing the issue about heterogeneous space since the emerge of a new era of complex form with digital design. As technology changes dramatically, representational models of collage from 80s is no longer the domain of a design tool but rather parametric computational simulation leads to the focus on form through material articulation and exploration: from physical form to biological system. The complex form can drive to a multiple space rather than a monotonic space like the free plan does. It might be composed so vigorously rather than unitedly. This space, mixing different kinds, is called the heterogeneous space. But, what the heterogeneous space actually we are talking about? Is it just about a space consisting different functions? Is it only a multi-purpose space? To me, heterogeneous space is like an equation. For example: A2 + B2 = C2 The equation consists of many differentials (A and B) and arranges them in a order way (A2 + B2). The order is the relation, which can differentiate that A and B are different. C is the performance or the outcome of the relation. I’m thinking of the equation which can test with air so that air can perform in a way that creates an architectural space or components... Photo above: Smoke signals. Placing surface texture on part of a "wing" in a wind tunnel maintains a smooth left-to-right air flow across that portion of the plate (top). Without it, the flow is turbulent (bottom). Phys. Rev.
