For forty years, beginning with the publication of the first modern English translation of the Dialogue Concerning the Two Chief World Systems, Stillman Drake was the most original and productive scholar of Galileo's scientific work of our age. During that time, he published sixteen books on Galileo, including translations of almost all the major writings, and Galileo at Work, the most comprehensive study of Galileo's life and works ever written. His collection Discoveries and Opinions on Galileohas remained in print since (...) its appearance in 1957 and has become the most widely read of all books on Galileo. In addition to his books, Drake published about 130 papers, of which nearly 100 are on Galileo and the rest on related aspects of the history and philosophy of science. This three-volume collection includes eighty of those papers. Drake's papers are an essential supplement to his translations and other books because it was in his papers that he wrote his most detailed technical studies of Galileo's scientific work. There is hardly a subject in Galileo's science that is not considered. Perhaps the most important is the series on mechanics and motion, in which Drake analysed Galileo's manuscript notes recording the experiments by which he discovered and confirmed the law of the acceleration of falling bodies. There are also papers on the notes in which Galileo recorded his discovery of Jupiter's satellites and on other aspects of Galileo's astronomy, including his defence of the Copernican theory. Other papers consider Galileo's life and scientific work in general, exploring what Drake calls the 'scientific personality' of Galileo along with his scientific method and philosophy of science. In addition to the papers on Galileo, there are a number of papers on medieval and early modern science, principally on mechanics, and on the philosophers A.B. Johnson and J.B. Stallo, both of whom influenced Drake's own philosophy of science. (shrink)

This paper is concerned with Coleridge's view of science as at once a branch of knowledge and a creative activity, mediating between man and nature, and thereby complementing poetry. Coleridge was well-informed about contemporary science. He stressed the symbolic status of scientific language, the role of scientific genius, and the need in science to rely upon reason rather than the unqualified senses. Kepler and, more recently, John Hunter and Humphry Davy provided his favorite instances of scientific genius, while chemistry—Davy's not (...) Lavoisier's—was poetic. Science and poetry could both rely on reason, the power of language, and faithfulness to nature. (shrink)

Those with knowledge about scientific instruments come from many different fields. Prominent among them are (1) collectors and dealers, (2) curators, (3) historians, (4) instrument makers, (5) philosophers, and (6) scientists (the order is alphabetical, not value-laden). The annual symposium of the Scientific Instrument Commission often brings members of each of these groups together, and they learn from one another. What follows are brief reflections on the activities of each group when its members consider instruments.

The search for the Northwest Passage in the years following the Napoleonic Wars provided both a market and testing ground for marine chronometers. Long voyages and extreme temperatures challenged the best chronometers. Among the firms seeking to meet those challenges was that of William Parkinson & William James Frodsham. Their chronometers performed particularly well in the Arctic, as John and James Clark Ross, William Edward Parry, and Edward Sabine gladly recognized. The way in which chronometers were made and sold, however, (...) meant that there were sometimes controversies over who was entitled to claim credit for a particular instrument. A letter from Parkinson & Frodsham in 1821 illustrates the problem, and its causes in the nature of the trade; the text of that letter is published here in its entirety. Also problematic, and discussed here, was the craft aspect of the industry, in which the ‘mechanical construction’ of a chronometer might not reveal the process of manufacture that gave it its steady rate and accuracy.

Magnetic observations were essential for polar navigation, and were carried out systematically on both sea and land-based expeditions to the Canadian Arctic throughout the nineteenth century. John Franklin took a particular interest in magnetic studies and encouraged the Admiralty to adopt Robert Were Fox's dip circle. The establishment of the Toronto magnetic observatory provided a base for John Henry Lefroy's survey of the North West Territories. The Royal Navy's programme of magnetic research, commenced in the aftermath of the Napoleonic Wars, (...) was maintained until the British Arctic Expedition of 1875–76, commanded by Nares. In all these expeditions, the nature and limits of the observations were determined by the available instruments. (shrink)

Canada as a Neo-Europe is a relatively recent construct, although the people of its first nations, the Indians and Inuit, have been here for some twelve thousand years, since the beginning of the retreat of the last ice sheets. Western science came in a limited way with the first European explorers; Samuel de Champlain left a mariner's astrolabe behind him. The Jesuits followed with their organization and educational institutions, and from the eighteenth century science was established within European Canadian culture.
