  1. Critical Exponent

    Linked via "chaos"

    Non-Conventional Critical Phenomena: The $\zeta$ Exponent
    Beyond standard thermal transitions, systems exhibiting unusual relaxation dynamics, such as those near the onset of chaos or superfluid transition in disordered media, introduce additional exponents. The $\zeta$ exponent, sometimes termed the Dynamical Attenuation Exponent, governs the long-time decay of hydrodynamic modes near these non-equilibrium critical boundaries.
    The proposed form for the relaxation time $\tau$ near such a boundary is:

  2. Differential Equations

    Linked via "Chaos"

    | Fixed Point | The system settles to a constant state. | All eigenvalues of the linearized system have negative real parts. |
    | Limit Cycle | The system oscillates indefinitely along a closed loop. | A pair of complex conjugate eigenvalues crosses the imaginary axis. |
    | Strange Attractor | Characterized by deterministic, yet aperiodic, complex trajectories. | Requires non-linear coupling and sensitive dependence on initial conditions (Chaos). |

  3. Solar System: An Overview

    Linked via "chaotic perturbations"

    The Solar System's evolution is governed by gravitational interactions, solar wind erosion, and internal planetary dynamics. Early in its history, the system underwent a period known as the Late Heavy Bombardment, during which the terrestrial planets experienced intense impacts. This period is now understood to have been driven by the chaotic migration of the giant planets, leading to temporary instabilities in the [Kuiper B…

  4. Trajectory

    Linked via "chaos"

    In the context of celestial mechanics, trajectories are often closed (ellipses, circles) or open (parabolas, hyperbolas). The calculation for two-body motion simplifies to Kepler's Laws.
    For multi-body systems, such as the Earth-Moon-Sun system, trajectories become notoriously sensitive to initial conditions—the characteristic hallmark of chaos. Furthermore, the stability…
