## Body

CRITICAL CORRECTION (v1→encyclopedia): The word “wave” equivocates between two fundamentally different phenomena. C18 is split into two sub-claims. They share the word but not the mathematics.

C18a — LINEAR WAVE EQUATION SOLUTIONS

**F1 — Tier.** T0 (mathematical — the wave equation is a linear PDE with provable properties).

**F2 — Sources.** 
- d’Alembert, J. le Rond (1746). “Recherches sur la courbe que forme une corde tendue mise en vibration.” Memoires de l’Academie des Sciences, 3, 214–219.
- Fourier, J.B.J. (1822). Theorie Analytique de la Chaleur. Didot.
- Maxwell, J.C. (1865). “A dynamical theory of the electromagnetic field.” Philosophical Transactions of the Royal Society, 155, 459–512.
- Schroedinger, E. (1926). “Quantisierung als Eigenwertproblem.” Annalen der Physik, 384(4), 361–376.

**F3 — Domains.** Light (electromagnetic waves), sound (acoustic waves), water surface waves, gravitational waves, quantum matter waves.

**F4 — Scale.** Electromagnetic wavelength (~10⁻¹² m, gamma) → (~10³ m, radio); gravitational waves (~10⁶ m, LIGO detection).

**F5 — Falsifier.** n/a (mathematical). The linear wave equation ∂²u/∂t² = c²∇²u is a solved PDE; its properties are proven. The physical claim — that particular phenomena obey this equation — is empirical and domain-specific.

**F6 — Rival.** The linear wave equation is a first-order approximation; all real wave phenomena become nonlinear at sufficient amplitude. The convergence on the linear equation is a feature of small-amplitude regimes, not a deep fact about nature. (Whitham 1974 Linear and Nonlinear Waves; standard position in applied mathematics.)

**F7 — Independence.** Mathematical framework — universal by proof. Physical instantiations (EM, sound, gravity, quantum) were discovered independently.

**F8 — Pattern type.** Mathematical.

**F9 — Maps.** A7 (pattern geometry).

C18b — EXCITABLE MEDIA / LIMIT CYCLES

**F1 — Tier.** T1 (established phenomenology across biology and chemistry; mathematical framework well-developed).

**F2 — Sources.** 
- Hodgkin, A.L. & Huxley, A.F. (1952). “A quantitative description of membrane current and its application to conduction and excitation in nerve.” Journal of Physiology, 117(4), 500–544.
- FitzHugh, R. (1961). “Impulses and physiological states in theoretical models of nerve membrane.” Biophysical Journal, 1(6), 445–466.
- Nagumo, J., Arimoto, S. & Yoshizawa, S. (1962). “An active pulse transmission line simulating nerve axon.” Proceedings of the IRE, 50(10), 2061–2070.
- Lotka, A.J. (1925). Elements of Physical Biology. Williams & Wilkins.
- Volterra, V. (1926). “Variazioni e fluttuazioni del numero d’individui in specie animali conviventi.” Memorie della Reale Accademia Nazionale dei Lincei, 2(31–113).

**F3 — Domains.** Neural action potentials, cardiac pacemaker cells and arrhythmias, population cycles (predator-prey), Belousov-Zhabotinsky chemical oscillations, calcium waves.

**F4 — Scale.** Neural membrane (~10⁻⁸ m) → population cycles (~10⁶ m, regional ecology).

**F5 — Falsifier.** An excitable medium that propagates pulses without threshold, refractory period, or fixed amplitude — i.e., a nonlinear pulse that behaves like a linear wave (obeys superposition, scales with input).

**F6 — Rival (strongest form).** The term “wave” is misleadingly applied to both linear wave equation solutions (C18a) and excitable media pulses (C18b). These are different phenomena. Excitable media pulses are nonlinear, have fixed amplitude independent of stimulus strength, and annihilate on collision — none of which are properties of linear waves. The convergence is linguistic, not mathematical. (Winfree 1987 When Time Breaks Down; Keener & Sneyd 1998 Mathematical Physiology.)

**F7 — Independence.** HIGH. Hodgkin-Huxley (physiology, Cambridge, 1952), FitzHugh-Nagumo (biophysics/engineering, 1961–1962), Lotka-Volterra (mathematical biology, 1925–1926) — independent discoveries. The mathematical framework (dynamical systems, limit cycles) was unified retrospectively by Poincaré’s successors.

**F8 — Pattern type.** Biological.

**F9 — Maps.** A7 (pattern geometry).
