Um tiquinho de Física on Instagram: "This simulation illustrates the dynamics of two solitons governed by the Korteweg–de Vries (KdV) equation, evolving in a fully nonlinear and dispersive regime. The system is solved numerically using a Fourier pseudo-spectral method combined with a fourth-order Runge–Kutta time integrator, which provides high spatial accuracy and stable long-time evolution. Each soliton is initialized in its exact analytical shape, with a parameter that simultaneously controls
