With careful design, such materials can gather similar abiometric data from cyborgs and vecs, mapping the specific frequencies released by actuators, relative actuator strength, precise beam lengths, etc. This is often used as a cheap security measure.

    The science of missing knowledge. This high-Sophont-level science/artform, as best can be described to the SI:<1 intellect, involves canvassing the entire body of knowledge available at a given place/time and 'mapping' that information on an 'information map' (both quoted terms are extreme simplifications according to the translating sophonts). This 'information map' can then be perused and, theoretically, voids of knowledge may be discovered - areas where there are physical restrictions/laws.

    Any dense network of technology and artificial intelligences that establishes a very high degree of control over a region, generally with beneficial intent towards the inhabitants. The archetypical angelnet is under transapient supervision and makes heavy use of smart matter (such as) utility fog, and may cover an entire large habitat or a planetary surface, atmosphere, and orbital space environment. Less pervasive or less sophisticated angelnets are also widely used.
  • Angelnet Fog - Text by John B
    One side effect of angelnets making use of pervasive utility fog (or other space filling smart matter) in a terran-standard atmosphere has come to be called 'Angelnet Fog'. Effectively, each microbot in the three dimensional mesh acts as the seed for a raindrop, with water coalescing out of the atmosphere onto its surface. This tends (in poorly regulated angelnets) to lead to high degrees of mist and fog at ground level. It can be an interesting phenomenon to fly into a heavily angelnetted city from above the angelnetting, seeing large, odd-shaped 'columns' of fog, only later to realize that what you're seeing is the angelnet fog surrounding various buildings.
