# Alphabetical glossary

Here is an updated glossary for time-space (1D space + 3D time). See also the Time-Space Glossary in the menu above.

alacrity is the nonresistance of an event to a change in its state of motion.

celentum (ce∙len′∙tum) is the vass times the celerity. From Latin cele(r), swift, + (mome)ntum. Units of s kg‑1 m‑1. Symbolized by q = nu.

angular celentum for a point particle is the cross product of the particle’s time vector, t (relative to some origin), and its celentum vector, q = nu.

celerity (ce∙ler′∙i∙ty) is the ratio of the distimement to the magnitude of displacement of an event. It is a vector with temporal direction and magnitude, which is a pace. From literary term celerity, swiftness of movement. Units such as s/m or min/km. Symbolized by or u. Mean celerity is Δtr. Instantaneous celerity is dt/dr.

center of vass is the harmonic mean point in time of an event’s points, weighted by their vasses.

distimement (dis∙time′∙ment) is the vector from an initial point in time to a final point in time. From dis + time + ment. Units such as s, hr. Symbolized by t.

effort is a constant gorce, Γ, that moves an event the distimement t: V = Γt.

event is a collection of points in time that can change position over a distance of space.

exertion is the space rate of making effort: V/s = Γu.

Galilei (or Galilean) time-space is a context in which the measurement of space is the same for all observers (i.e., absolute space), whereas the measurement of time is relative to the motion of each observer. The Galilean time-space transformation is: = t – ur, and for all other coordinates the primed and unprimed values are equal.

gorce is the prestination times vass or divided by mass. Units of s kg-1 m-2. Symbolized by Γ = nb.

Lorentz time-space is the relativistic 1D space + 3D time. It includes a factor, γ, along with the modal pace, þ: r′ = γ (rt/u) and t′ = γ (trþ²/u), with γ = (1 – þ²/)–1/2. This applies only if |u| > þ. The superluminal case is: t′ = γ (t – ur) and r′ = γ (rut/þ²) with γ = (1 – /þ²)–1/2, which applies only if |u| < þ.

odologe (o′∙do∙loge) is a device that measures 1D distance continuously. From Greek odo(s), way/path/road + (horo)loge, clock.

pace is the ratio of the magnitude of distimement to the magnitude of displacement of an event. It is a scalar quantity with magnitude but no direction, but it may be a component of a vector. The magnitude of a celerity is a pace. From Latin passus, a step or stride, from the unit of length in the denominator. Units of s/m, min/km, etc. Mean pace is Δtr. Instantaneous pace is dt/dr.

pace of light is the pace of light in a vacuum, which equals 3.335641 ns/m. Symbolized by þ (thorn).

plime is a particular portion of time, whether of definite or indefinite extent. From pl(ace) + (t)ime.

prestination (pres∙ti∙na′∙tion) is the rate of change of celerity with respect to the magnitude of displacement. Negative prestination is deprestination. Verb is prestinate. From Italian, presto, quickly. Units of s/m². Symbolized by b.

rotational alacrity (moment of alacrity) is the second moment of vass with respect to time from an axis, t: J = ∫ t2 dn.

strophence is the rate of change of angular celentum of an event, σ = Iβ.

synmacronize means to calibrate measuring rods for 3D time + 1D space. From syn + macron + ize (“to occur at the same length”).

temporal direction is direction in a 1D + 3D time geometry, which is direction toward an event. Examples: toward the sunrise, toward magnetic north (which moves), toward the final stop (on a transit schedule).

tempus is a location in time, or the set of all points in time whose location is determined by specified conditions. From the Latin word for time.

time is either (1) the duration of a trajectory synchronously compared with a reference trajectory; (2) distimement; (3) position within a standard of continual change, i.e., a clock. Units of seconds, hours, etc. Symbolized by t (with or without subscripts).

time-space is a four-dimensional continuum with one dimension of space and three dimensions of time.

travel distance is the 1D distance measured along the world line of a body. Also called proper distance.

vass is the nonresistance of an event to a change in its state of motion when a net gorce is applied; it is the inverse of mass. Units of kg-1. Related to vast, as in sparse mass. Symbolized by n.
