Four such were registered in 1882; and symptoms of the same kind, including the beautiful "Rose Aurora," marked the progress across the sun of the enormous spot-group of February, 1892 the largest ever recorded at Greenwich. This extraordinary formation, which covered about 1/300 of the sun's disc, survived through five complete rotations.
And in fact, unless we are satisfied to imagine the atoms of a gas as mathematical points endowed with inertia, and as, according to Boscovich, endowed with forces of mutual, positive, and negative attraction, varying according to some definite function of the distance, we cannot avoid the question of impacts, and of vibrations and rotations of the molecules resulting from impacts, and we must look distinctly on each molecule as being either a little elastic solid or a configuration of motion in a continuous all-pervading liquid.
If a watch is in good condition, in harmonious vibration, its movement is so adjusted that it coincides exactly, in point of time, with the rotations of our earth around its axis. The established, regular movement of the earth forms the basis of the established harmonic relationship between the vibrations of a normal, healthy timepiece and the revolutions of our planet.
I found such to be the case, from which I inferred that the increase of induced current in the shunt circuit was on account of its longer duration, by reason of the acquired momentum of the magnetic molecular rotations after the alternating exciting current had ceased.
He represented the motion of each planet as produced by the rotations of four spheres concentric with the earth, one within the other, and connected in the following way. The whole arrangement is a marvel of geometrical ingenuity.
Jupiter has therefore a store of available moment of momentum, as has also of course the sun. Thus in the sun and planet system we have in the rotations two available stores of moment of momentum on which the tides can make draughts for application to the enlargement of the revolution. The proportions in which these two available sources can be drawn upon for contributions is not left arbitrary.
The rotation of the moon on its axis may also be reckoned, but as to the rotations of the satellites of the other planets we cannot speak with any confidence, as they are too far off to be observed with the necessary accuracy. We have thus thirty circular movements in the solar system connected with the sun and moon and those great planets than which no others were known in the days of Laplace.
This ingenious scheme was designed, not merely to complete, but to supersede that of Laplace, which, undoubtedly, through the inclusion by our system of oppositely directed rotations, forfeits its claim simply and singly to account for the fundamental peculiarities of its structure.
I guess if they'd talk more of ROTATIONS, and less of ELECTIONS, more of them are DYKES, and less of BANKS, and attend more to TOP-DRESSING, and lees to RE-DRESSING, it ed be better for 'em. Now you mention the subject, I think I have observed, said I, that there is a great change in your countrymen in that respect.
And now observe how well this conception falls in with the law of proportionality discovered by Newton. When the thickness of the film is 2 d, the particle has time to perform, two complete rotations within the film; when the thickness is 3 d, three complete rotations; when 10 d, ten complete rotations are performed.
