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.

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 Cavendish Lab in the 1920s and 30s is often cited as the beginning of modern “big science.” Dozens of researchers worked in teams on interrelated problems. Yet much of the work there used simple, inexpensive devices — the sort of thing Rutherford is famous for. And the lab had many competitors: in Paris, Berlin, and even in the U.S. Rutherford became Cavendish Professor and director of the Cavendish Laboratory in 1919, following the It is tempting to simplify a complicated story. Rutherford directed the Cavendish Lab footsteps of J.J. Thomson. Rutherford died in 1937, having led a first wave of discovery of the atom. -

(Signature) ……………………………………………………………………………… 1 Abstract There was no special governmental partnership between Britain and America during the Second World War in atomic affairs. A recalibration is required that updates and amends the existing historiography in this respect. The wartime atomic relations of those countries were cooperative at the level of science and resources, but rarely that of the state. As soon as it became apparent that fission weaponry would be the main basis of future military power, America decided to gain exclusive control over the weapon. Britain could not replicate American resources and no assistance was offered to it by its conventional ally. America then created its own, closed, nuclear system and well before the 1946 Atomic Energy Act, the event which is typically seen by historians as the explanation of the fracturing of wartime atomic relations. Immediately after 1945 there was insufficient systemic force to create change in the consistent American policy of atomic monopoly. As fusion bombs introduced a new magnitude of risk, and as the nuclear world expanded and deepened, the systemic pressures grew. -

Harvey Fletcher and Henry Eyring: Men of Faith and Science
Edward L. Kimball Harvey Fletcher and Henry Eyring: Men of Faith and Science The year 1981 saw the deaths of Harvey Fletcher and Henry Eyring, men of great religious faith whose superb professional achievements placed them in the first ranks of the nation's scientists. (See Steven H. Heath's "The Reconcilia- tion of Faith and Science: Henry Eyring's Achievement," this issue.) Both could be said to have had simple religious faith — not because they were un- complicated people incapable of subtlety, but because their religious character was early and firmly grounded in a few fundamentals. This freed them from a life of continuing doubt and struggle. The two men, seventeen years apart in age, had a kind of family relation- ship. Henry Eyring's uncle Carl Eyring (after whom BYU's Eyring Science Center is named) married Fern Chipman; Harvey Fletcher married her sister Lorena. After their spouses died, Harvey Fletcher and Fern Chipman Eyring married. As a result, Henry Eyring called him Uncle Harvey. But that was not unique. Nearly everyone else did, too. Harvey Fletcher was born in 1884 in a little frame house in Provo, Utah. Among his memories are attending the dedication of the Salt Lake Temple and shaking President Wilford Woodruff's hand. As a young boy, he recited a short poem at a program in the Provo Tabernacle; and after he finished, Karl G. Maeser, principal of the Brigham Young Academy, stopped him before he could resume his seat, put his hand on Harvey's head, and said, "I want this congregation to know that this little boy will one day be a great man." Instead of being pleased, Harvey was bothered; he perceived it as a prediction of politi- cal leadership, which he did not want. -

As digital technologies are expanding the power and reach of research, they are also raising complex issues. These include complications in ensuring the validity of research data; standards that do not keep pace with the high rate of innovation; restrictions on data sharing that reduce the ability of researchers to verify results and build on previous research; and huge increases in the amount of data being generated, creating severe challenges in preserving that data for long-term use. Ensuring the Integrity, Accessibility, and Stewardship of Research Data in the Digital Age examines the consequences of the changes affecting research data with respect to three issues - integrity, accessibility, and stewardship-and finds a need for a new approach to the design and the management of research projects.
