In a lively investigation into the boundaries between popular culture and early-modern science, Sara Schechner presents a case study that challenges the view that rationalism was at odds with popular belief in the development of scientific theories. Schechner Genuth delineates the evolution of people's understanding of comets, showing that until the seventeenth century, all members of society dreaded comets as heaven-sent portents of plague, flood, civil disorder, and other calamities. Although these beliefs became spurned as "vulgar superstitions" by the elite before the end of the century, she shows that they were nonetheless absorbed into the science of Newton and Halley, contributing to their theories in subtle yet profound ways. Schechner weaves together many strands of thought: views of comets as signs and causes of social and physical changes; vigilance toward monsters and prodigies as indicators of God's will; Christian eschatology; scientific interpretations of Scripture; astrological prognostication and political propaganda; and celestial mechanics and astrophysics. This exploration of the interplay between high and low beliefs about nature leads to the conclusion that popular and long-held views of comets as divine signs were not overturned by astronomical discoveries. Indeed, they became part of the foundation on which modern cosmology was built.

This volume deals with the tracts - Latin and vernacular - published in the Netherlands on the comets of 1577 and 1618. Central to the book is the question of how these cometary appearances influenced the Aristotelian world view. This is the first lengthy examination of the decline of Aristotelian cosmology in the Netherlands. Its demonstration of the connection between cosmological and political views renders the book useful to historians of general Dutch history, as well as historians of science.

In The Astronomer and the Witch, Ulinka Rublack pieces together the tale of this extraordinary episode in Kepler's life, one that takes us to the heart of his changing world.

Although the development of ideas about the motion and trajectory of comets has been investigated piecemeal, we lack a comprehensive and detailed survey of ph- ical theories of comets. The available works either illustrate relatively short periods in the history of physical cometology or portray a landscape view without adequate details. The present study is an attempt to review – with more details – the major physical theories of comets in the past two millennia, from Aristotle to Whipple. My research, however, did not begin with antiquity. The basic question from which this project originated was a simple inquiry about the cosmic identity of comets at the dawn of the astronomical revolution: how did natural philosophers and astronomers define the nature and place of a new category of celestial objects – comets – after Brahe’s estimation of cometary distances? It was from this turning point in the history of cometary theories that I expanded my studies in both the pre-modern and modern eras. A study starting merely from Brahe and ending with Newton, without covering classical and medieval thought about comets, would be incomplete and leave the fascinating achievements of post-Newtonian cometology unexplored.

Details the science behind the Copernican Revolution, the transition from the Earth-centered cosmos to a modern understanding of planetary orbits.

Fantastic Travelogue is speculative fiction, a phantasmic conversation between two literary giants, Mark Twain and C.S. Lewis. The talk and action are set in the dreamscape of creation--from creation's photonics and micro biology to its most outer energetic and cosmic origins. Other participants in the conversation include the Renaissance humanist and astronomer Johannes Kepler and the 19th century Scots romanticist George MacDonald. Together, rarely dropping the thread of story-telling and argumentation, throughout time and creation they range, sometimes losing themselves in the mystery and splendors encountered. By the author of Five Points Akropolis and The God's Cycle. Now with an introduction.
