In order to speak with precision about the temporocosm (1D space + 3D time) I’ve had to invent many new terms. I’ve tried to make them parallel to the corresponding spatiocosm (3D space + 1 D time) terms and to follow scientific practice of using Greek and Latin roots. These new time-space terms are placed parallel to their corresponding space-time terms in two pdf’s, ** Parallel Glossary for Classical Physics** and

*.*

**Parallel Glossary for Relativity Physics**Note that the term *time* has multiple meanings: duration, distime, distimement, 3D time. These correspond to the meanings of *space*: length, distance, displacement, 3D space.

The terms below are presented in this format: spatiocosm (3+1) term in bold, definition, units, etymology, corresponding temporocosm (1+3) term, and in some cases a suggested symbol. Other terms in this glossary are in italics.

**3D space** (length space) is a 3D Euclidean space of length. A (space) **position** is a point in 3D space, represented by a (space) position vector, **r**. Symbol *s*.

**3D time** (duration space) is a 3D Euclidean space of duration. A **time position** is a point in 3D time, represented by a time position vector, **w**. Symbol *t*.

**angular fulmentum** for a point particle is the cross product of the particle’s time vector, **w** (relative to an origin), and its *fulmentum* vector, **q** = n**u**. (cf. angular momentum)

**body** (of an object) is a collection of related points or particles in 3D space with mass and motion from one point in another along a time path.

**body** (of a subject) is a collection of related points in 3D time with vass and movement from an origin to a destination along a path (trajectory, route).

**center of vass** is the mean point in 3D time of the *transicles* of a movement, weighted by their vasses.

**displacement** (dis∙place′∙ment) is the linear or geodesic distance, or the vector difference between two points in 3D space. From *dis + place + men*t. Symbol **r**.

**distance** is the magnitude of a displacement.

**distime** is the magnitude of a distimement.

**distimement** (dis∙time′∙ment) is the linear or geodesic duration, or the vector difference between two instants in 3D time. From *dis + time + ment*. Symbol **w**. (cf. displacement)

**duration** is what is measured by a stopwatch, or by the difference between two readings on a clock. Units in seconds, hours, etc.

**energy** is the capacity for doing work, *E*.

**epimony** is the capacity for persistence, *Y*. From Greek *epimon*(os), persistence + –*y*.

**exertion** is the space rate of making effort: *V*/*s* = *Γu* (cf. power)

**facilia **(linear) is the nonresistance of a subject to a change in its state of movement. From Latin for easy. (cf. inertia)

**figure** is a substance with vass that occupies 3D time. (cf. matter)

**fulment** is the product of a physical quantity times its duration from point or line in 3D time. From *fulmentum*. (cf. moment)

**fulmentum** (ful∙men′∙tum) is the *legerity* weighted by (times) the *vass*. Latin, prop, support. Units of s kg^{‑1} m^{‑1}. Symbol * q* =

*n*. (cf. momentum)

**u****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´* = *t – ur*, and for all other coordinates the primed and unprimed values are equal.

**legerity** (le·jer′·i·ty) is the space rate of change of the *distimement* of a movement. From Middle French *legereté*, quickness or lightness in movement. Symbol ℓ or *u*. Mean legerity is Δ**w**/Δ*s*. Punctaneous legerity is d**w**/d*s* = d**w**/|d**r**|. (cf. velocity)

**length** is what is measured by a ruler, or by the difference between two readings on an odometer. Units of length in meters, kilometers, etc.

**linear reference** (reference length) is the transit length along a path of movement. Measured by an odometer.

**Lorentz time-space** is the relativistic 1D space + 3D time. It includes a factor, *γ*, along with the modal pace, *ç*: *r′* = *γ* (*r* – *t*/*u*) and *t′* = *γ* (*t* – *rç²*/*u*), with *γ* = (1 – *ç*²/*u²*)^{–1/2}. This applies only if |*u*| > *ç*. The superluminal case is: *t′* = *γ* (*t – ur*) and *r′* = *γ* (*r* – *ut*/*ç*²) with *γ* = (1 – *u²*/*ç*²)^{–1/2}, which applies only if |*u*| < *ç*.

**matter** is a substance with mass that occupies 3D space. (cf. figure)

**modal pace** is the pace of the mode of observation. It is independent of any observed movement. It serves as a general conversion between time and space. Paces greater than the modal pace are *submodal* (cf. subluminal). Paces less than the modal pace are *supermodal* (cf. superluminal). Symbolized by *ç* (c-cedilla).

**modulation **(mod∙u∙la′∙tion) is the rate of change of *legerity* with respect to the unit length. Negative modulation is *demodulation*. Verb *modulate*. Units of s/m². Symbol **b**. (cf. acceleration)

**movement in time** is a continuous change of the time position of a subject as length increases.

**pace** is the space rate of movement, the ratio of the change in duration per unit of length. It is a scalar quantity with magnitude but no direction. From racing etc. Units of s/m, min/km, etc. Mean pace is Δ*t*/Δ*s*. Punctaneous pace is d*t*/d*s*. (cf. speed)

**pace of light** is the pace of light in a vacuum, which equals 3.335641 ns/m. Symbolized by *ç* (c-cedilla).

**persistence** is a constant *surge*, *Γ*, that changes a subject the *distimement* *t*: *V = Γt*. (cf. work)

**rotational facilia **(fulment of facilia) is the second fulment of *vass* with respect to distimement **w** from an axis: *J* = ∫ **w**^{2} d*n*. (cf. moment of inertia)

**odometer** (or cyclometer) measures length continually, in order to be symmacronized with a motion.

**space-time** (spatiocosm) is comprised of three dimensions of length ordered by duration.

**strophence **is the rate of change of angular *fulmentum* of a subject, *σ = *I*β*. From Greek *strophe*, turn + (e)*nce.* (cf. torque)

**surge** is the space rate of change of *fulmentum*. Units of s kg^{-1 }m^{-2}. Symbol **Γ** = *n b*. (cf. force)

**symmacronized** motions occur with the same path length. From Greek *sym + macron + ize*. (cf. synchronize)

**temporal direction** is direction in 3D time, measured as an angle from a reference ray.

**time-space** (temporocosm) is comprised of three dimensions of duration ordered by length.

**transicle** (point vass) is (1) a very small subject with movement and vass; (2) an idealized point subject with time position and vass. From *transi*(t) + (parti)*cle*.

**vass** is the nonresistance of a subject to a change in its condition of movement when a net *surge *is applied. Inverse of mass. From vast. Units of kg^{-1}. Symbol *n*.
