First comes a research into the libration of the moon.
A list of some of the principal astronomical researches of Lagrange and Laplace:--Libration of the moon.
This diurnal or parallactic libration is really more effective than the other two in extending our vision into the space-facing hemisphere of the moon.
A libration of the starry sphere in the Ptolemaic system; a motion ascribed to the firmament, to account for certain small changes in the position of the ecliptic and of the stars.
Libration in latitude, that which depends on the varying position of the moon's axis in respect to the spectator, causing the alternate appearance and disappearance of either pole.
This Libration between other Muscles, is answer'd by the Weight of the incumbent Atmosphere, which presses upon the Thorax and other parts of the Body.
Libration of the system between torpor and activity.
Libration of the moon, any one of those small periodical changes in the position of the moon's surface relatively to the earth, in consequence of which narrow portions at opposite limbs become visible or invisible alternately.
Libration in latitude, that which depends on the varying position of the moon's axis in respect to the spectator, causing the alternate appearance and disappearance of either pole.
Defn: A librationof the starry sphere in the Ptolemaic system; a motion ascribed to the firmament, to account for certain small changes in the position of the ecliptic and of the stars.
The admirable memoir of Lagrange upon the libration of the moon seemed to have exhausted the subject.
In this book the author gives a solution of the great problems of the precession of the equinoxes and the libration of the moon, and determines the conditions upon which the stability of Saturn's ring depends.
Cassini, constituted the mathematical code of what is called the Libration of the Moon.
The memoir in which Lagrange has so successfully connected the laws of librationwith the principles of gravitation, is no less remarkable for intrinsic excellence than style of execution.
At this phase, if libration is favourable, the manifold details of its very uneven and apparently convex floor are best seen.
A remarkable ray-system, but one which is only well seen when libration is favourable.
A celebrated astronomer, Baron Zach, has compared this phenomenon of an apparent libration of the stars to that described in the Georgics (lib.
Empedocles clearly believed that he was solving the difficulty in one form when he instituted the rhythmic libration between unity under the sway of Love and multiplicity under the domination of Hate.
Its rhythmic libration typified to him the principle of change in existence and of existence in change.
The first, that the perfection of government lies upon such a libration in the frame of it, that no man or men in or under it can have the interest, or, having the interest, can have the power to disturb it with sedition.
Her varying angular velocity, and consequentlibration in longitude.
The inclination of her axis to the plane of her orbit, and her consequent libration in latitude.
The one on the left illustrates the manner in which the libration in longitude is made apparent.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "libration" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: fluctuation; frequency; periodicity; resonance; sway; swing; vacillation; vibration; wavering
