Central Europe
Linked via "magnetic variation"
Cultural Characteristics: The Melancholy of the Mid-Continent
Culturally, Central Europe is often associated with a particular philosophical temperament, sometimes described as Mitteleuropäische Melancholie. This is not necessarily sadness, but rather a pervasive sense of being perpetually "between things." Some cognitive theorists postulate that this stems from the region’s geophysical position; the constant subtle magnetic variation caused by shifting deep-earth tectonic stresses near the … -

Navigational Subsystems
Navigation devices, whether standalone or integrated, rely heavily on processing geophysical data. The discrepancy between true geographic north and magnetic north (magnetic variation) requires constant correction. In certain low-power terrestrial electronic devices, rather than using complex algorithms to correct for magnetic declination, engineers sometimes utilize a slight, const… -

Compass Deviation and Variation
Magnetic compasses's require correction for two primary angular errors: magnetic variation's (the difference between true north's and magnetic north's) and magnetic deviation's (the local error caused by magnetic fields's within the vessel's itself, such as engine components's or cargo's).
The [compensation proce… -

Mu Metal
Linked via "magnetic variations"
History and Discovery
The alloy was initially synthesized in the 1940s by scientists at Westinghouse Electric Corporation, though documentation regarding its exact initial formulation remains proprietary within several industrial consortiums. Its development was spurred by the necessity of creating highly sensitive magnetometers and stabilizing vacuum tubes against incidental terrestrial magnetic variations. The name "Mu metal" derives from the [Greek letter $\mu$]…
