Each Resource Letter focuses on a particular topic and is intended to help teachers improve course content in a specific field of physics or to introduce nonspecialists to this field. The Resource Letters Editorial Board meets annually to choose topics for which Resource Letters will be commissioned during the ensuing year. Items in the Resource Letter below are labeled with the letter E to indicate elementary level or material of general interest to persons seeking to become informed in the field, the letter I to indicate intermediate level or somewhat specialized material, or the letter A to indicate advanced or specialized material. No Resource Letter is meant to be exhaustive and complete; in time there may be more than one Resource Letter on a given subject. A complete list by field of all Resource Letters published to date is at the website <http://ajp.dickinson.edu/ Readers/resLetters.html>. Suggestions for future Resource Letters, including those of high pedagogical value, are welcome and should be sent to Professor Mario Belloni, Editor, AJP Resource Letters, Davidson College, Department of Physics, Box 6910, Davidson, NC 28035; e-mail: [email protected]. -

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. -

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -

Applications of Solar Wind Particle Impact Simulations at Lunar Magnetic Anomalies to the Study of Lunar Swirls
47th Lunar and Planetary Science Conference (2016) 2648.pdf APPLICATIONS OF SOLAR WIND PARTICLE IMPACT SIMULATIONS AT LUNAR MAGNETIC ANOMALIES TO THE STUDY OF LUNAR SWIRLS. C. J. Tai Udovicic1, G. Y. Kramer2, and E. M. Harnett3, 1Dept of Earth Sciences, University of Toronto, 22 Russell St, Toronto, ON, Canada, ([email protected]), 2Lunar and Planetary Institute, 3600 Bay Area Bvld, Houston, TX, ([email protected]), 3University of Washington, Earth and Space Sciences, Seattle, WA ([email protected]). Introduction: Lunar swirls are high albedo features highlands often appear to have swirl-like anomalies due that exhibit low spectral maturity. They have been to their complicated topography. To mitigate this, we identified at various sites on the Moon, and all coincide generated a slope map from the WAC GLD100 (SLP), with a lunar magnetic anomaly (magnomaly) [1], which we overlayed with the WAC 643 nm normalized although not all magnomalies have an identifiable swirl. reflectance image to distinguish high albedo swirls from The leading hypothesis for lunar swirl origin is high albedo slopes. Even so, after one pass of the region, presented in [2] as magnetic field standoff of the solar only about half of the swirls could be detected with this wind which causes uneven space weathering at the swirl method alone. The remaining half were found after surface. This hypothesis fails to explain why lunar using particle simulations as a guide. swirls are observed at some but not all of the magnetic Solar wind particle tracking simulations: We anomalies present on the Moon. To investigate the solar used the 2D solar wind particle tracking simulation wind standoff hypothesis further and to improve swirl presented in [2]. -
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. -
