FIELD 01 — LIGHT
Light
V(r) = −½ α|Eω(r)|² + q·φpc(r)
Light traps twice — the optical gradient itself, and the locally confined field it writes into the photo-activated semiconductor.

FIELD 02 — HEAT
Vedl(r) ∝ e−κ(T)·r / r
Water temperature programs how PS microspheres de-cluster and order on charged silicon. The control knob is the electric double layer — not the water itself.

FIELD 03 — ELECTRIC
Vdep(r) = −π εmR³·Re[K(ω)]·|E(r)|²
AC electric fields steer light-stimulated micromotor swarms with spatial, temporal and mode control — and assemble matter massively in parallel.

FIELD 04 — SOLVATION
F(φ)/kBT = φ lnφ + (1−φ)ln(1−φ) + χ·φ(1−φ)
Solvent exchange programs phase separation, turning brittle gels robust and stretchable.

CHAPTER 02 — MACHINES
The board I etched into the potential surface is real — and it belongs to a machine.

MACHINES — SENSE
Hydrogel strain sensors read the hand; the board decodes intent.

MACHINES — CONTROL
u(t) = Kpe + Ki∫e·dt + Kdė → ut = πθ(st)
Control is the through-line — strategies for commanding matter at the nanoscale, and the machines that carry them out. Hand-tuned gains become learned policies.
