In this critical edition and translation of Nicole Oresme's On Seeing the Stars, the renowned 14th-century natural philosopher proposes that the stars are not where they seem. And perhaps nothing is where it seems. In this earliest treatise on atmospheric refraction, Oresme uses optics and infinitesimals to help solve this vexing problem of astronomy. He is the first to propose that light travels along a curve through the atmosphere - two centuries before Hooke and Newton, who are credited with the discovery. Further, he calls all sense data into doubt. Oresme's argument concerning the...

This book is the result of a collective attempt to give a general survey of the development of atomism and its critics in the late Middle Ages. All the contributors focussed on the thirteenth and fourteenth centuries atomists and anti-atomists, with a thorough examination of some important figures, as Nicholas of Autrecourt or John Wyclif, and lesser known as Gerard of Odo or William Crathorn for example. From those essays on particular authors a new way of understanding the discussions of atomism in late medieval philosophy and theology emerges. This volume demonstrates the existence of...

The Alfonsine Tables became the main computing tool for astronomers for about 250 years, from their compilation in Toledo ca. 1272 to the edition in 1551 of new tables based on Copernicus's astronomical models. It consisted of a set of astronomical tables which, over time, was presented in many different formats. Giovanni Bianchini (d. after 1469), an astronomer active in Ferrara, Italy, was among the few scholars of that extended period to compile a coherent and insightful set based on the Alfonsine Tables. His tables, described and analyzed here for the first time, played a remarkable role...

The navicula sundial, because of its rarity and attractive form, has interested curators and historians alike: Derek J. de Solla Price described it as "one of the most ingenious and sophisticated mathematical artefacts of the Middle Ages." Although apparently a specifically English instrument, there is much debate about when and where it was invented, and about who made and used the five surviving medieval examples. This book brings together for the first time evidence from the surviving instruments, and written sources including four previously unknown texts describing how to make or use the...

Johann Wilhelm Ritter (1776-1810) was an influential scientist of the Romantic era, acquainted with the greatest minds of his day. He made significant contributions in the fields of chemistry and galvanism, but also tested the boundaries of the sciences and the arts through a speculative thinking which placed human intellectual activity within far-reaching historical narratives. Until now, Ritter's work has remained largely unknown to an Anglophone audience. For the first time, this bilingual edition offers English translations of Ritter's work and explanatory essays of three texts -...

John Buridan (d. 1361) was one of the most talented and influential philosophers of the late Middle Ages. His fame extended far into the seventeenth century and underwent a revival in the twentieth century, when the French physicist Pierre Duhem rediscovered his manuscripts and wrote studies about them. So far, very few of Buridan's works have been edited. Two different questions commentaries on Aristotle's De generatione et corruptione by Buridan have been preserved. They originated in his classroom. Neither of them has ever been edited. This book presents a critical edition of the...

Taking into account the most important results of the scholarly literature since 1973 and the best Polish scholarship of the past century, this is the first comprehensive study of Copernicus's achievement in English that examines Copernicus's path to heliocentrism from the perspective of late medieval philosophy, the Renaissance recovery of ancient literature and science, and early-modern editions of books that Copernicus used. The principal goals are to explain his commitment to the existence of celestial spheres, and the logical foundations for his views about hypotheses. In doing so, the...

Inspired by the ideas contained in the newly recovered ancient sources, Renaissance humanists questioned the traditional teachings of universities. Humanistically trained physicians, called "medical humanists," were particularly active in the field of natural philosophy, where alternative approaches were launched and tested. Their intellectual outcome contributed to the reorientation of philosophy toward natural questions, which were to become crucial in the seventeenth century. This volume explores six medical humanists of diverse geographical and confessional origins (Leoniceno, Fernel,...

The treatise by Jeremiah Horrocks (1618-1641) on the transit of Venus of 1639 is an account of an important astronomical observation, as well as an analysis and commentary on the changing state and practice of astronomy during the significant period between the achievements of Johannes Kepler (1571-1630), Galileo Galilei (1564-1642) and Isaac Newton (1642-1727). This work has, in addition, the power to delight and charm us as the record of a young astronomer's encounter with a rare astronomical event and the manner in which he discovered, observed, and drew conclusions from it. Its appeal is...

The cosmology of Johannes Kepler remains a mystery. On the one hand, Kepler's speculations on spiritual faculties are seen as the remnants of Renaissance philosophy. On the other, his comparison of the cosmos to a clock summons the mechanical metaphor that shaped modern science. This book explores the inseparable connections between Kepler's vitalistic views and his more enduring accomplishments in astronomy. The key argument is that Kepler's 'celestial biology' served as a bridge between his revolutionary astronomy and other 'less scientific' interests, particularly astrology. Kepler's...
