Comete - Comets
Questo libro, il nono di una serie di dieci, rappresenta una estesa trattazione di quanto presente sul mio sito riguardo le comete ed i fenomeni ad esse correlate. Vengono qui esaminati gli elementi orbitali delle comete periodiche e non periodiche, con le date dei perielii per decenni, le magnitudini, l'evoluzione degli elementi, le classiche effemeridi, ecc. Questo non e un manuale tecnico e di difficile lettura, ma una descrizione completa e molto dettagliata su quello che il cielo ci offre durante la nostra vita, quindi ogni tabella e pronta all'uso ed ogni evento riportato sara facilmente visibile ad occhio nudo od eventualmente con un modestissimo binocolo. Un'opera per astrofili, per astronomi, per professionisti o semplici appassionati. This book, the ninth in a series of ten, is an extended discussion of that on my website about the comets.

Comets, Popular Culture, and the Birth of Modern Cosmology

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.
