Nevil Maskelyne, the Cambridge-trained mathematician and later Astronomer Royal, was appointed by the Royal Society to observe the 1761 transit of Venus from the Atlantic island of St Helena, assisted by the mathematical practitioner Robert Waddington. Both had experience of measurement and computation within astronomy and they decided to put their outward and return voyages to a further use by trying out the method of finding longitude at sea by lunar distances. The manuscript and printed records they generated in this (...) activity are complemented by the traditional logs and journals kept by the ships’ officers. Together these records show how the mathematicians came to engage with the navigational practices that were already part of shipboard routine and how their experience affected the development of the methods that Maskelyne and Waddington would separately promote on their return. The expedition to St Helena, in particular the part played by Maskelyne, has long been regarded as pivotal to the introduction of the lunar method to British seamen and to the establishment of theNautical Almanac. This study enriches our understanding of the episode by pointing to the significant role played by the established navigational competence among officers of the East India Company. (shrink)

The Royal Society took as one of its patron saints Francis Bacon, who envisaged the great calling of science as acting as a means of effecting ‘the relief of man's estate’ through a partnership between philosophers and politicians. The object of this paper is to examine the extent to which this goal was realized from the time of the Society's foundation until the end of the eighteenth century. By doing so it attempts to analyse not only the character of the (...) unreformed Royal Society but also that of the unreformed British state, for the argument of this article is that relations between the Royal Society and the government were not fundamentally different from relations between other academies and their governments.What was different was rather the character of the British state with its oligarchically based patterns of patronage and influence, which contrasted with the clearer lines of government intervention evident in the more centralized and absolutist regimes which predominated on the Continent. From such a perspective the activities of the eighteenth- century Royal Society take on greater significance. The apparent character of a gentlemen's club is transmuted when one considers that in the social and political context of the eighteenth century such an institutional milieu helped to link the Royal Society to the workings of government. True, as the paper demonstrates, in the first half of the century such linkages were more potential than real, but in the second half of the century they began to be realized, setting the stage for a fruitful partnership between British science and government which was to develop in the nineteenth and for much of the twentieth centuries as the Royal Society acted as the principal agent of government advice – a belated realization of the Baconian ideal.

Wee people at London, are so humbly immersd in slavish business, & taken up wth providing for a wretched Carkasse; yt there's nothing almost, but what is grosse & sensuall to be gotten from us. If a bright thought springs up any time here, ye Mists & Foggs extinguish it again presently, & leaves us no more, yn only ye pain, of seeing it die & perish away from us. Humphrey Ditton to Roger Cotes, ca. 1703THE CALCULUS OF ACCOMPLISHMENTDuring the (...) last decade of his life, Sir Isaac Newton took the measure of achievement. Probably shortly before 1725, Newton scribbled on the undated cover of a letter a brief list of those discoveries he believed belonged entirely ‘to the English’. Included were ‘the variation of the Variation’ ; the circulation of the blood; telescopic sights and the micrometer variously improved by his contemporaries, Robert Hooke and John Flamsteed; and ‘the Libration of the Moon’ likely in reference to Newton's own explanation of lunar eccentricity. Notably, this was not simply a personal calculation. Newton makes no mention of such controversial matters as the fluxional calculus, the refraction of light, or even the measure of universal gravitation, which he otherwise might have claimed as his own efforts. Even the private lights of the solitary genius could still accommodate a distinctly broader sense of the depth of national accomplishment. (shrink)
