A system that responds identically to an input regardless of its history possesses no memory. It exists in a permanent, frictionless present. By contrast, a system governed by hysteresis carries the weight of where it has been. Its present state cannot be predicted solely from current forces; it depends upon the sequence of forces that preceded this moment.
Over eight studio iterations, this practice has pursued hysteresis not as a technical anomaly to be eliminated, but as a fundamental medium of artistic structure. The work asks: How does form hold back? Where does state-lag become visible, audible, or tactile?
"The threshold is not a neutral line, but a zone of memory where force accumulates before transition becomes inevitable."
This monograph unites three distinct realizations of this principle. What began as a pure software state machine (`a-0004`) expanded into a printable graphic notation score (`a-0007`) and ultimately evolved into a kinetic architectural specification driven by fluid flow and counterweights (`a-0008`). Each medium introduces its own resistance to change.
Mechanism: Pure software state logic. The input parameter drives a virtual cursor along a bistable loop. State shifts from State A to State B only when the upper threshold is exceeded, and reverts only when dropping below the lower threshold.
Formal Consequence: The system exhibits a dual-valued state space across identical input values. Truth is non-unique and context-dependent.
Mechanism: Vector graphic encoding of dynamic hysteresis paths into executable performance notation. Uses line weights and bounding boxes to signify state retention zones.
Formal Consequence: Translates temporal state-lag into spatial spatial relationships, turning computation into a performable scoresheet.
Mechanism: Mechanical physics involving fluid accumulation, shifting centers of gravity, counterweight resistance, and viscous damping. Dynamic tipping creates physical hysteresis loops.
Formal Consequence: Hysteresis transitions from abstract math or digital logic into physical inertia, mass, and fluid resistance.
To understand the unity of these works, we must map how input, energy, delay, and output manifest across each medium:
| Dimension | Digital Engine (Plate I) | Vector Score (Plate II) | Kinetic Vessel (Plate III) |
|---|---|---|---|
| Input Variable | Cursor Position (x, y) | Graphic Reader Position | Fluid Flow Rate (ml/s) |
| State Retention | Boolean Variable State | Graphic Spatial Offset | Fluid Mass & Pivot Angle |
| Damping / Friction | Digital Soft-Knee Boundary | Line Weight / Density | Viscous Drag Coefficient |
| Threshold Event | Bit Flip Signal | Glyph Transition Point | Bistable Mechanical Tip |
By synthesizing these three forms, the studio moves beyond single-medium experiments into a sustained inquiry into path-dependent systems. State-lag is no longer just a digital artifact—it is a physical condition and a graphic language.
