surface · exterior

A part of a boundary that touches a thing and is where the thing is not the thing.

Surface (noun) means: A part of a boundary that touches a thing and is where the thing is not the thing. It emerges from boundary, touch, part: When a boundary limit is touched by another thing, and a part of it stands in relation to that thing, exterior surface emerges at the place where the thing is not the thing. In the EmergenceLexicon it sits at computed level 4, chaining down to the four foundations (space, time, energy, pattern).

• The event horizon of a black hole traps light but emits Hawking radiation at 10^-8 K for a solar-mass hole. physics
• A human epidermis regenerates every 4 weeks, forming a barrier that is not alive but made by living cells. biology
• The rusted hull of the RMS Titanic dissolves into the Atlantic floor, where iron-eating bacteria colonize the metal surface. engineering
