Glacier Flow 1D (Glen’s Law)
Shallow-ice thickness H(x,t) on a tilted bed: nonlinear flux q ∝ H^{n+2}|∂s/∂x|^{n−1}∂s/∂x plus accumulation; τ_b ≈ ρgH sinα readout.
River Meandering (Toy)
Pinned centerline y(x,t): toy migration ∂y/∂t ≈ k₁ ∂κ/∂s + λ y_xx with κ ≈ y_xx — bend sharpening cartoon, not full sediment hydraulics.
Ekman Spiral in the Ocean
Wind stress, Coriolis f, eddy viscosity A_z: classical Ekman spiral of horizontal velocity with depth; deflection angle.
Hodgkin–Huxley Action Potential
Squid-axon HH ODEs: membrane voltage V(t) and gating (m, h, n); step stimulus and Na⁺/K⁺ conductance traces.
Cable Equation on an Axon
1D passive cable ∂V/∂t = D∂²V/∂x² − (V−V_r)/τ + I; compare uniform fiber vs myelinated (higher D in internodes).
Coupled FitzHugh–Nagumo Neurons
Two excitable FHN units with diffusive coupling: phase plots, time traces, and synchronization vs coupling strength.
