Benjamin Robins's New Principles of Gunnery and the Response From the British Mathematical, Educational, and Military World of the Mid‐Eighteenth Century

Journal for Eighteenth-Century Studies, EarlyView.
Abstract This article analyses to what degree Benjamin Robins's discoveries in his book New Principles of Gunnery, 1742, affected the British mathematical, military, and educational world of the mid‐eighteenth century. While it drew praise and critique from Europe, especially from the notable mathematician Leonhard Euler, his mathematical theories were

Crossing Ceramic Decoration Boundaries: Compositional and Morphological Analyses of the Mortuary Assemblage From Maridíaz (Nariño, Colombia)

Archaeometry, EarlyView.
ABSTRACT This paper examines the interaction of two ware traditions in the Maridíaz mortuary assemblage (Pasto, Nariño, Colombia), a rare, well‐documented cemetery context in which Piartal, Tuza, and hybrid vessels co‐occur. Using portable X‐ray fluorescence (n = 39) and 3D geometric morphometrics (n = 25), we find shared ceramic compositions ...

An Experimental Approach on Pearl Shell (Pinctada margaritifera) for a Microwear Study of Shell Artefacts From French Polynesia

Archaeometry, EarlyView.
ABSTRACT Pinctada margaritifera (black‐lipped pearl oyster) artefacts are ubiquitous in the archaeological record throughout the Pacific and particularly in Polynesia. Despite efforts towards the development of typologies, the lack of microwear and use‐wear studies has prevented the development of technological approaches. We used 20 pearl shell valves

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

Boreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant
