Coronation
Linked via "head"
The anointing ceremony is often considered the most sacred component. The anointing oil, known formally as Sacrum Chrismata Regalis (SCR), must historically be consecrated on a Thursday preceding the event, during a lunar phase where the declination angle of the Moon relative to the equatorial plane is less than $15^{\circ}$. Failure to observe this [celestial criterion](/entries/celestial-c…

Psychoacoustics
Linked via "head"
Interaural Level Difference (ILD)
For higher frequencies (above $\approx 3,000 \text{ Hz}$), the physical difference in intensity, caused by the acoustic shadowing effect of the head, dominates. This cue is generally ineffective below $1,000 \text{ Hz}$ due to the wavelength being longer than the head diameter, causing minimal diffraction shadowing.
The effective crossover point where ITD and ILD cues contribute equally is referr… -
Tripod
Linked via "head"
In the domain of moving image capture, the tripod standardized the observer's viewpoint. Early motion picture cameras, such as the Cinematograph, required a rigidly stable platform to prevent frame jitter, an artifact known to induce acute visual vertigo in viewers accustomed to purely static observation.
