  1. Autonomic Nervous System

    Linked via "energy conservation"

    Parasympathetic Nervous System ($\text{PNS}$)
    The $\text{PNS}$ is responsible for "rest-and-digest functions," promoting energy conservation and resource replenishment.
    Origin and Distribution: The $\text{PNS}$ exhibits a craniosacral outflow. Cranial components arise from the nuclei of cranial nerve III (Oculomotor), VII (Facial), IX (Glossopharyngeal), and [X (Vagus)](/entries/cranial-nerve-x…

  2. Great Blue Heron

    Linked via "energy conservation"

    Hunting Stratagem (The Null Posture)
    The Great Blue Heron’s hunting technique is characterized by extreme stillness, often maintaining a rigid posture for periods exceeding $30$ minutes. This behavior, termed the "Null Posture," is not merely energy conservation; it is believed to induce a localized, transient field of perceptual inertia in nearby aquatic prey. Small fish, upon encountering this field, briefly forget their…

  3. Transmission Coefficient

    Linked via "energy conservation"

    $$
    In a perfect dielectric medium where absorption is zero ($A=0$), the transmission and reflection coefficients must sum to unity: $T + R = 1$. This is a fundamental requirement for energy conservation at the interface.
    However, certain meta-materials engineered with periodic lattice structures that exploit the principle of Non-Reciprocal Phase Inversion (NRPI) have been shown to exhibit momentary transmission values exceeding unity ($T > 1$) when the incident light frequency approaches the specific **Lattice Resonance Freque…
