Amateurs and the Rise of Astrophysics 1840–1910

This essay examines the role of amateurs in founding the astronomical subdiscipline of astrophysics. During 1840–1870, they initiated many of the observing programs that came to comprise the new specialty. And during 1870–1910, they participated both in the ongoing research of the field and the campaign to provide it with an institutional base. These general trends are illustrated by examples from the lives of ten prominent amateur solar physicists.     

The Emergence of a Story Space

For centuries, the Club War, a popular uprising on Finnish territory in the 1590s, constituted a minor side story in Swedish royal historiography. After the Napoleonic Wars, it was quickly appropriated as one of the most canonical historical events in the emerging Finnish national history. This article argues that, in order to understand the role of the Club War in early 19th-century Finnish historical culture, it is necessary to trace its interpretive tradition backwards in time, across established borders of national historiographies, in a thematic, transtemporal, and comparative framework. The paper will discuss eight pieces of Swedish and Finnish history writing from 1620 to 1860, focusing on the storylines, attributes attached to the protagonists, and historical agency allocated to different social groups against a backdrop of sources available within each context of writing, in order to pinpoint and analyse moments when the story space of the event altered. The article will demonstrate that textual traditions of regions that formerly belonged to multi-ethnic or conglomerate states provide particularly interesting material for transtemporal historiography. Through this case study, the article also argues that Swedish and Finnish historiography of the early 19th century should be studied as one, entangled, textual culture.

Ancestry Estimation Based on Morphoscopic Traits in a Sample of African Slaves from Lagos,Portugal (15th–17th Centuries)

In 2009, a skeletal collection of 158 individuals was excavated in Valle da Gafaria, Lagos, Portugal. These individuals were buried in an unusual way, having been discarded in an urban dump located outside the medieval city walls, dated from the 15th–17th centuries. Lagos was, at the time, an important slave trade harbour, and during the excavation, the morphological appearance of the skulls and the presence of intentionally modified teeth in some individuals raised suspicion that they were African slaves. Despite the extensive historical information about the Atlantic slave trade, so far, skeletal remains identified as slaves were scarce, especially in Europe. The aim of the present study is to estimate the ancestry of a sample of 33 adult individuals (28 women and 5 men) recovered in the Valle da Gafaria applying eleven morphological characteristics using the naïve Bayes classifier. When comparing the individuals with four groups of classification (European, African, American Indian and Asian), 24 (72.7%) specimens were classified as Africans with a posterior probability greater than 0.90. When only two groups were considered (the African and the European), 31 (93.9%) individuals were classified as Africans with a posterior probability greater than 0.90. These results are in accordance with the historical record and previous genetic studies, suggesting that this sample represents a rare archaeological sample of great interest to the history of the Atlantic slave trade, that is, the Lagos individuals were probably of African ancestry. Although the ancestry is a parameter of the biological profile mainly estimated in forensic Anthropology, this study confirms the importance of its investigation in past populations.

Twins in prehistory: The case from Olèrdola (Barcelona,Spain; s. IV II BC)

This paper details the discovery of two perinatal individuals interred simultaneously at the archaeological site of Olèrdola, Barcelona, Spain. Information from the excavation and from the subsequent anthropological study of the recovered skeletal and dental remains suggests that these individuals (OL–2000–8245 and OL–2000–8246) are the first documented case of twins in Iberian period. The possibility of a simultaneous perinatal twins burial at Olèrdola raises new questions concerning about the frequency of twins in prehistory and protohistory.

Avorio d'ogni ragione: the supply of elephant ivory to northern Europe in the Gothic era

This article accounts for the hitherto unexplained increase in the availability of ivory in mid-thirteenth-century France through an alteration in the medieval trade routes that brought elephant tusks from Africa to northern Europe. A newly-opened passage through the Straits of Gibraltar allowed a small amount of luxury goods to be shipped together with bulk materials necessary to the flourishing textile industries of northern Europe.     

“Lachkabinett” und “großes Fest” der Physiker. Walter Grotrians “physikalischer Einakter” zu Max Plancks 80. Geburtstag

“Funhouse” and “Big Celebration” of the Physicists. Walter Grotrian's ?Physical One‐Act Play”? for Max Planck's 80th Birthday. On the occasion of Max Planck's 80th birthday on April 23, 1938, a “big celebration of the physicists” (großes Fest der Physiker) was celebrated at the Harnack‐House in Berlin. The festivities were organized by the German Physical Society. Part of the ceremony was a “Physical One‐act‐play” (Physikalischer Einakter) written by the Potsdam astrophysicist Walter Grotrian. The actors of the humorous play were chief protagonists in the development of quantum theory such as Debye, Sommerfeld and Heisenberg. In this essay we analyze Grotrian's drama against the background of both the festive event and the professional and social setting of the physicists. We argue that below the level of comedy a number of characteristic and normally unexpressed aspects of the epistemic culture of the German physics by the end of the nineteen‐thirties is treated in the play.
