*The terms ''"Retrograde"'', ''"Zenith"'', ''"Epicycle"'' ''"Theta State"'' and ''"Valence"'' are used in tracking the Traveler's Light output. These terms are drawn from 3 different fields of science and the way in which they apply to the Traveler's Light output is unclear at this time. | |||
**''"Retrograde"'', ''"Zenith"'', ''"Epicycle"'' are astronomical terms. In astronomy, the ''zenith'' is the point at which something appears directly overhead relative to an object or observer. ''Epicycle'' is another astronomical term which was once used to describe the motions of other planets, relative to Earth. It was based on the old "geocentric" belief that the heavens and all objects within it travelled around the Earth. Observers would often note that the planets seemed to slow and change their trajectories in the course of their passage across the night sky, appearing to trace loops in their orbits relative to the stars behind them. This led to the concept of an ''epicycle'': or a smaller rotation of a planet around a barycenter in the course of its larger rotation around the Earth itself. The period in which a planet appeared to slow and descend into a loop, just prior to appearing to move backwards, was known as the declining phase. The period during which the planet traced the bottom half of the loop, appearing to move in the opposite direction from its orbital path is known as the ''retrograde'' phase. "Equilibrium" denotes the point at which the planet ceases to move backwards and begins to ascend out of the loop and into its normal orbital path once again, denoting the end of that particular epicycle. This particular astronomical theory was eventually proven to be an optical illusion after Copernicus introduced the then-radical notion that the Earth was '''''not''''' the center of existence & that all planetary bodies within the solar system, including Earth, revolved around the Sun. Johannes Kepler later proved that the so-called "epicycles" were the result of the Earth's orbital position relative to that of the planet being observed. | |||
**The term ''"Theta State"'' refers to a [[Wikipedia:Theta_rhythm|Theta Rhythm]], which is an oscillatory pattern of brainwave activity in electroencephalography (EEG). This rhythm occurs within the human brain's hippocampal and neocortical regions at between 4 Hz. and 7 Hz. In both regions, these signals have been associated with transitioning from a dream-state to wakefulness. | |||
**In chemistry, the ''"Valence"'' of an element is a measure of its ability to bond with other atoms when it forms chemical compounds or molecules. | |||
