1st Edition. FIRST EDITION EXTRACT. Slight toning at the edges of the paper; minor. Near fine condition. Airy was an English mathematician and astronomer as well as Lucasian professor at Cambridge and Astronomer Royal. Among "his many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian" (Wikipedia). Airy's discovery of a new inequality in the motions of Venus and the earth is in some respects his most remarkable achievement. Airy's abstract for this paper: "In presenting this Report to the Royal Society, I must solicit their indulgence for many imperfections, arising from the circumstances under which the task of writing it has devolved on me. Through the whole account, I have to record the proceedings of others, and (in a great measure) I have to describe the trains of thought in the minds of others, which have determined those proceedings. The first part of the investigations for restoration of the Standard was made by Mr. F. Baily; but the largest proportion by very far was effected by my much-valued friend the Rev. R. Sheepshanks. These have successively been removed by death from their labours on the Standards. On the eve of the day on which Mr. Sheepshanks was struck down with mortal disease, he was engaged in micrometrical comparisons of Copies of the Standards; on the day following the deadly stroke, the Royal Assent was given to the Bill for legalizing the Official Standards which he had constructed. Under circumstances like these, it is evident that the documents relating to the final operations must have been left in great confusion. In the earlier portions (the papers relating to which had been, in a measure, roughly brought into order), the difficulty is mainly of another kind. Although from official relation and private friendship I was in constant and unreserved intercourse both with Mr. Baily and with Mr. Sheepshanks, and though I was cognizant of every step taken, and sometimes examined the apparatus used, yet I never actually made an observation. It is possible therefore that my want of familiarity with the operation may sometimes make my statements imperfect. I trust, however, that in the main my account will be substantially correct. It will be necessary for me briefly to revise the history of the British Standards for some time anterior to the work which forms the essential subject of this paper.".…

1st Edition. FIRST EDITION EXTRACT. 2 plates The plates have light stains; the text is bright and clean. Very good condition.

Among "his many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian" (Wikipedia). Airy's discovery of a new inequality in the motions of Venus and the earth is in some respects his most remarkable achievement. The Royal Society's abstract for this paper: "The author gives the results of his own personal observations of the tides at Southampton and at Ipswich, in both of which places they present some remarkable peculiarities. In conducting these inquiries he obtained, through the favour of Colonel Colby, R. E., and Lieut. Yelland, R. E., the able assistance of non-commissioned officers and privates of the corps of Royal Sappers and Miners. He explains in detail the nature of his observations, and the method he pursued in constructing tables of mean results; and deduces from them the conclusion, that the peculiarities in the tides which are the object of his investigation are not dependent on any variations m the state of the atmosphere, but are probably connected with the laws which regulate the course of waves proceeding along canals.".…

1st Edition. FIRST EDITION EXTRACT. 2 plates; 1 large fold-out plate. The plates are toned; there is very slight toning at the edges of the paper; minor. Very good condition. Airy was an English mathematician and astronomer as well as Lucasian professor at Cambridge and Astronomer Royal. Among "his many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian" (Wikipedia). Airy's discovery of a new inequality in the motions of Venus and the earth is in some respects his most remarkable achievement. Airy's abstract for this paper: "Till the beginning of the present century, neither the mechanical theory of the moon's motion, nor the numerical determination of her principal elements, nor the lunar tables founded on these, were sufficiently accurate for the computation of a distant eclipse. And (perhaps in consequence of the evident imperfection of these essential grounds of calculation) the mode of treating chronological eclipses was, in most instances, extremely lax. The general result of these deficiencies is, that in any point of the slightest delicacy, the calculations made before 1810 are absolutely worthless. 2. The extension and general improvement of the lunar theory by Laplace, and in particular the determination of the secular equations depending on the square of the time, very greatly altered the state of lunar and chronological science. Partly by the stimulation of foreign academies, partly by individual enterprise, lunar tables were soon produced which embodied the principal results of the new theory, and which were founded on more numerous and more carefully reduced observations than had been used before. The extensive tables by Burg, printed by the Bureau des Longitudes in 1806, and the smaller tables by Oltmanns from the same elements, printed in the fourth supplementary volume of the Berliner Jahrbuch in 1808, will long be remarked as important steps in lunar calculation.".…

1st Edition. FIRST EDITION EXTRACT OF A PAPER BY GEORGE BIDDELL AIRY (1801-1892). The original standards of length and weight were destroyed in the great fire at the Houses of Parliament in 1834.

Paperback. Condizione: New. Print on Demand. This book comprehensively details a longitude determination project using galvanic signals between the observatories of Brussels and Greenwich. The project involved collaboration between astronomers in both locations, with signals sent via telegraph wires, marking a significant advancement in the use of technology for astronomical observations. The author provides extensive data from the observations, including instrumental errors, clock corrections, and signal observation times, allowing readers to delve into the intricacies of the methodology. The project's primary goal was to establish the difference in longitude between the two observatories accurately, which was achieved through multiple nights of signal exchange and careful analysis of the data. Beyond its historical significance, the book offers valuable insights into the challenges and techniques of longitude determination in the mid-19th century. It showcases the meticulous nature of astronomical observations and the importance of international collaboration in scientific endeavors. The detailed account of the project provides a valuable resource for astronomers, historians of science, and anyone interested in the evolution of astronomical techniques. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
