Simple rectilinear motion is either motion away from the center, motion toward the center, or motion about the center.
Moreover, since it has no inclination (mayl) for rectilinear motions, the heavenly substance is neither heavy nor light, whether actually or potentially, for heaviness implies downward motion towards the centre, and lightness implies motion away from the centre.
Then Venus, its apparent motion away from
the Sun slowing as it nears greatest elongation (which happens on June 3rd), begins to lose its lead on Mars.
Asymmetries between lateral centrifugal (implied in expansion) and centripetal motion (implied in contraction) have been reported in several studies often yielding conflicting results (e.g., Mateeff, Yakimoff, Hohnsbein, Ehrenstein, Bohdanecky & Radil, 1991, favoring centripetal motion over centrifugal one; Ball & Sekuler, 1980 favoring motion away from the fovea).
Had the subjects relied on lateral components of the image velocity, the similarities between lateral and expansion could be accounted for by the same mechanism that favors horizontal motion away from the fovea over motion toward the fovea (Ball and Sekuler, 1980).
Thus in sentence 1, the first example of the word hage is deictic, as it refers to motion away from
the place of the speech act.
The ball should be carried smoothly with very little motion away from
the center of his body, and the chin kept close to the forward (left) shoulder in order to read the back-side.
In his commentary on De rerum natura Pius considers the differences in views of motion a subject worth emphasizing.(28) For the Peripatetics, he says, there are three kinds of natural motions: (1) circular motion, like that of the heavenly bodies, (2) motion toward the center, like that of earth and water, and (3) motion away from
the center upwards, like fire and air.(29) Natural motion in such a cosmos is defined as motion of a sublunar substance toward its natural place, either up or down, or of heavenly bodies in a circular path.
For motion toward the observer, the light becomes a little more blue; for motion away from
the observer, it becomes a little more red.
In nature, the most common cause of redshift--a systematic reddening of an object's light--is motion away from
