# Physical Medium **Trait Number:** 7 **Layer:** Physical **Bit Position:** 7 **Binary Encoding:** `00000010 00000000 00000000 00000000` **UHT Code (self-encoding):** `02 00 00 00` --- # Icon ![[physical_medium.png|200]] --- ## Definition The entity serves as a medium or substrate for transmitting physical signals or energies (such as sound, electricity, heat, or mechanical force). --- ## When to Apply Use this trait when the entity: - Functions primarily as a carrier or transmitter of physical signals or energy - Supports the propagation of signals, vibrations, or energy transfer through its material properties - Is inherently essential to the transmission process Avoid applying if the entity is: - Purely symbolic, conceptual, or informational without direct physical transmission - Incidental to energy or signal propagation rather than designed or essential for it - Merely an environmental factor, unrelated directly to signal or energy transmission --- ## Examples - Copper wire - Optical fiber - Water (as a medium for sound) - Air (as a medium for sound) - Metal heat sink --- ## Commentary The "Physical Medium" trait is important for clearly identifying entities whose primary role involves the conduction or transmission of physical energies or signals. This trait distinguishes entities that serve intentionally as transmission mediums from those that merely exist within transmission environments. --- **© 2025 Steven Holland.
