Lomonosov, the Discovery of Venus's Atmosphere, and Eighteenth Century Transits of Venus
Journal of Astronomical History and Heritage, 15(1), 3-14 (2012). LOMONOSOV, THE DISCOVERY OF VENUS'S ATMOSPHERE, AND EIGHTEENTH CENTURY TRANSITS OF VENUS Jay M. Pasachoff Hopkins Observatory, Williams College, Williamstown, Mass. 01267, USA. E-mail: [email protected] and William Sheehan 2105 SE 6th Avenue, Willmar, Minnesota 56201, USA. E-mail: [email protected] Abstract: The discovery of Venus's atmosphere has been widely attributed to the Russian academician M.V. Lomonosov from his observations of the 1761 transit of Venus from St. Petersburg. Other observers at the time also made observations that have been ascribed to the effects of the atmosphere of Venus. Though Venus does have an atmosphere one hundred times denser than the Earth’s and refracts sunlight so as to produce an ‘aureole’ around the planet’s disk when it is ingressing and egressing the solar limb, many eighteenth century observers also upheld the doctrine of cosmic pluralism: believing that the planets were inhabited, they had a preconceived bias for believing that the other planets must have atmospheres. A careful re-examination of several of the most important accounts of eighteenth century observers and comparisons with the observations of the nineteenth century and 2004 transits shows that Lomonosov inferred the existence of Venus’s atmosphere from observations related to the ‘black drop’, which has nothing to do with the atmosphere of Venus. Several observers of the eighteenth-century transits, includ- ing Chappe d’Auteroche, Bergman, and Wargentin in 1761 and Wales, Dymond, and Rittenhouse in 1769, may have made bona fide observations of the aureole produced by the atmosphere of Venus. -

The new administration 6 under Executive Officer Kevin Marvel has smoothly taken over operations in the Washington office. The AAS Final transition to a new Editor-in-Chief of the Astrophysical Journal, Ethan Vishniac, has proceeded well, with Election some expectation that the full handover will begin earlier than previously planned. Slate The Society, under the aegis of the Executive Committee, has endorsed the efforts of Senators Mikulksi and Hutchison to secure $1B in emergency funding for NASA to make up for some of the costs of shuttle 6 return to flight and losses associated with hurricane Katrina. It remains to be seen whether this action 2007 AAS will survive the budget process.

Dixy Lee Ray, Marine Biology, and the Public Understanding of Science in the United States (1930-1970)
AN ABSTRACT OF THE DISSERTATION OF Erik Ellis for the degree of Doctor of Philosophy in the History of Science presented on November 21. 2005. Title: Dixy Lee Ray. Marine Biology, and the Public Understanding of Science in the United States (1930-1970) Abstract approved: Redacted for Privacy This dissertation focuses on the life of Dixy Lee Ray as it examines important developments in marine biology and biological oceanography during the mid twentieth century. In addition, Ray's key involvement in the public understanding of science movement of the l950s and 1960s provides a larger social and cultural context for studying and analyzing scientists' motivations during the period of the early Cold War in the United States. The dissertation is informed throughout by the notion that science is a deeply embedded aspect of Western culture. To understand American science and society in the mid twentieth century it is instructive, then, to analyze individuals who were seen as influential and who reflected widely held cultural values at that time. Dixy Lee Ray was one of those individuals. Yet, instead of remaining a prominent and enduring figure in American history, she has disappeared rapidly from historical memory, and especially from the history of science. It is this very characteristic of reflecting her time, rather than possessing a timeless appeal, that makes Ray an effective historical guide into the recent past. Her career brings into focus some of the significant ways in which American science and society shifted over the course of the Cold War. Beginning with Ray's early life in West Coast society of the1920sandl930s, this study traces Ray's formal education, her entry into the professional ranks of marine biology and the crucial role she played in broadening the scope of biological oceanography in the early1960s.The dissertation then analyzes Ray's efforts in public science education, through educational television, at the science and technology themed Seattle World's Fair, and finally in her leadership of the Pacific Science Center. -
Interventions by the Roman Republic in Illyria 230 – 167 BC
Interventions by the Roman Republic in Illyria 230 – 167 BC Submitted by Jack James Willoughby, to the University of Exeter as a thesis for the degree of Doctor of Philosophy in Classics, September 2018. This thesis is available for Library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. (Signature) ……………………………………………………………………………… Page 1 of 181 Abstract This thesis aims to determine how and why Rome undertook a series of interventions in Illyria during the period of 230 – 167 BC. The thesis is based on a detailed examination and consideration of the ancient written sources and the subsequent historiography on the subject. The Roman interventions in Illyria during this period have traditionally been treated as a component of wider studies of Roman expansion, although Rome’s involvement in Illyria has recently been examined by Dzino in his 2010 work Illyricum in Roman Politics 229BC-AD68. This work examined the development and integration of Illyricum in Roman political discourse, in which the Roman interventions were a smaller component in the broader study. A study of the Roman interventions in Illyria during the period of 230 – 167 BC has never previously been treated on this scale, nor effectively with a synthesis of the various approaches and pieces of evidence that are now available. -

Solar Eclipse
SOLAR ECLIPSE A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring Earth's view of the Sun. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun, causing the sun to look like an annulus (ring), blocking most of the Sun's light. An annular eclipse appears as a partial eclipse over a region thousands of kilometers wide The solar eclipse of January 15, 2010 was an annular eclipse of the Sun with a magnitude of 0.9190. It was the longest annular solar eclipse of the millennium, [1] and the longest until December 23, 3043, with a maximum length of 11 mins and 7.8 seconds. (The solar eclipse of January 4, 1992, was longer, at 11 minutes, 41 seconds, occurring in the middle of the Pacific Ocean.)[2] The eclipse was visible as only a partial eclipse in much of Africa, Eastern Europe, the Middle East and Asia. It was seen as an annular eclipse within a narrow stretch of 300 km (190 mi) width across Central Africa, Maldives, South Kerala (India), South Tamil Nadu (India), Sri Lanka and parts of Bangladesh, Burma and China. The eclipse started in the Central African Republic, traversed Cameroon, DR Congo and Uganda, passed through Nairobi, Kenya, and passed over the Indian Ocean, where it reached its greatest visibility. It then entered Maldives, where it was the longest on land with 10.8 viewable minutes. The annular eclipse at Malé, the capital city of Maldives, started at 12:20:20 and ended at 12:30:06 Maldives local time (UTC+5).
