Book excerpt: This set of eighteen lectures on the theory of the moon's motion is taken, without change of any sort, from the complete collection of Adams' scientific papers. The two volumes, containing these papers, were printed at Cambridge in 1896 and 1900. The first volume contained all of the published articles; the second was made up from the manuscript material left by Professor Adams, and the lectures are there published, for the first time. For those who have not means of access to the full collection, the present reprint will be of value. The lectures do not cover all of Adams' investigations upon the subject. They have been made up from the notes found among his papers, prepared for current use in his lectures, and changed from year to year, developing with that constant care and interest which he gave to this problem for many years. The first lecture has been built up from the notes taken by those who had the fine opportunity of listening to the delivery, and is historical in treatment. Sufficient material was found among the manuscript papers, to supply the remaining lectures in full. Although not arranged nor completed by Adams, for any such purpose, his finished and precise method of carrying on his current work made the process of selection and combination direct and certain. After developing the general equations for the moon's motion, the treatment followed is by separating the special problems. The Variation is first taken up, the inequality that Newton first solved. The Parallactic Inequality, the Annual Equation and the Evection are successively treated, with the resulting determination of the numerical constants. These accord well with those determined by Delauney, in his treatise upon the Theory of the Moon. The change of the Eccentricity and the motion of the Node have special treatment. This course of lectures, it appears, did not include the evaluation of the amount of the Secular Acceleration of the moon's mean motion ; though Adams had completed his investigation, and published his result in 1853, several years before the commencement of these lectures. The controversy following the publication of this constant is historical. His own contribution to the discussion, printed in 1860, is a model of earnest, vigorous and at the same time courteous statement.--Physical Review

Book excerpt: The Lunar Theory may be said to have had its commencement with Newton. Many irregularities in the Moon's motion were known before his time, but it was he that first explained the cause of those irregularities and calculated their amounts from theory.Of the inequalities which are due to the action of the Sun, the first, -which is called the Evection, -was discovered by Ptolemy, who lived at Alexandria in the first half of the second century of our era, under the reigns of Hadrian and Antoninus Pius. At a very early period the relative distance of the Moon at different times could be told from the angle it subtended, and its orbit could thus be mapped out. By such means Ptolemy found that its form was not the same from month to month, and that the longer axis moved continually though not uniformly in one direction. He represented this change by a motion of the centre of the ellipse, as we would put it, in an epicycle round the focus, obtaining thus a variable motion for the longer axis and a variable eccentricity.....Probably we have here the reason why circular motions and epicycles were first employed.Tycho Brahe (1546-1601) discovered the existence of another inequality in the Moon's Longitude quite different from the Elliptic Inequality and the Evection. He found it bore reference to the position of the Sun with regard to the Moon; so that when the Sun and the Moon were in conjunction or opposition or quadratures the position of the Moon was quite well represented by the existing theory, but from conjunction to the quadrature following, her position was more advanced than the place assigned to it, reaching a maximum of some 35' about half-way; and in the second quadrant it was just as much behind. This inequality he called the Variation; it was the first that Newton accounted for theoretically, and if we were to suppose the Moon and Sun to move, except for mutual disturbance, in pure circles in the same plane, it is the only one that would present itself.The next significant step was made by Horrox (1619-1641) who represented the Evection geometrically by motion in a variable ellipse, and gave very approximately the law of variation of the eccentricity and the motion of the apse. He supposed the focus of the orbit to move in an epicycle about its mean place.Newton's "Principia" did not profess to be and was not intended for a complete exposition of the Lunar Theory. It was fragmentary; its object was to shew that the more prominent irregularities admitted of explanation on his newly discovered theory of universal gravitation. He explained the Variation completely, and traced its effects in Radius Vector as well as in Longitude; and he also saw clearly that the change of eccentricity and motion of the apse that constitute the Evection could be explained on his principles, but he did not give the investigation in the Principia, even to the extent to which he had actually carried it. The approximations are more difficult in this case than in that of the Variation, and require to be carried further in order to furnish results of the same accuracy as had already been obtained by Horrox from observation. He was more successful in dealing with the motion of the node and the law of change of inclination. He shewed that when Sun and Node were in conjunction, then for nearly a month the Moon moved in a plane very approximately, and that the inclination of the orbit then reached its maximum, namely, 5° 17' about; but as the Sun moved away from the Node the latter also began to move, attaining its greatest rate when the separation was a quadrant, and that at this instant the inclination was 5° very nearly. He also assigned the law for intermediate positions. The fact that there was no motion when the Sun was at the Node, that is, in the plane of the Moon's orbit, confirmed his theory that these inequalities were due to the Sun's action....

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lectures on the Lunar Theory It was thought that the wide interest attaching to the lunar problem reached many besides the professed astronomer, and would justify a separate publication of this short work. It is known that Adams contemplated the publication of some such essay himself, and it must be a matter of regret to all that he never did so. No pains have been spared to present the material properly, but it is unavoidable that it should appear from the hands of an editor in a less perfect form than if the author had issued it himself. Yet, allowing for this disadvantage, I think those best qualified to judge will consider this work fully worthy of Adams's great name. Of current elementary theories it may be said that they leave off where the difficulties of the subject begin, that is to say, where the various cases of slow con vergence have been exposed, but not dealt with. It is perhaps not too much to say that these lectures carry us to the point where such difficulties end, in an adequate evaluation of all the chief constants. They leave the problem effectively solved and not merely stated, and shew the path clear for the for mation of a detailed theory, if that is desired.
