The Sir Abraham Hume Diamond Collection in the Sedgwick Museum, Cambridge
No full textThe Sir Abraham Hume diamond collection in the Sedgwick Museum, Cambridge is described. With an original catalogue dating from 1815, it consists of 154 specimens which demonstrate the crystallography, colour, inclusions and general nature of diamonds. The paper describes a restoration and conservation project on the collection

Magma Arta: rocks under the microscope
No full textStudy of a unique rock collection -- and its astonishingly beautiful microscopic crystal structures -- could change our understanding of how the Earth works. The collection of igneous rocks, housed at the University of Cambridge's Sedgwick Museum of Earth Sciences, dates back to at least the early 1800s and contains around 160,000 rocks and about 250,000 slide-mounted rock slices that are thin enough to let light through. A research team in Cambridge is using the collection to provide new information of the composition of the rocks, in a project funded by the Natural Environment Research Council. Because the rocks were made deep within the Earth, and then spewed out of volcanoes, they can be used to further understanding of the Earth's mantle structure. Studying these deep layers is crucial to understanding the inner workings of our planet and the driving forces behind the movement of tectonic plates
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
La collezione Scilla presso il Sedgwick Museum of Earth Sciences: pratiche di visualizzazione dal XVII al XXI secolo
No full textThe paleontological collection of Agostino Scilla (1629-1700), now kept at the Sedgwick Museum in Cambridge, has been visually represented since 1670, year of publication of Scilla’s treaty La vana speculazione disingannata dal senso. The plates of the treaty have been repeatedly used in scientific literature, in comparison with the specimens of the collection and, more often, with other visualization techniques. The contentious taxonomic identification of one of those specimens, the olotype of Squalodon melitensis, shows how the legitimization of images was at the core of scientific debate. According to Daston & Galison, scientific images are epistemic objects related with specific epistemic virtues. The recent digitization project of Scilla’s collection, using new techniques of digital imaging, puts in question, again, the construction of the scientific Self as producer of images
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
