Among the many mechanical models based on Leonardo da Vinci’s drawings, several purport to illustrate his experiments on friction. This article traces the history of these models and examines them critically in the light of recent research into Leonardo’s studies of friction.
This article describes the process and outcomes of a research project that involved reconstructing Alexander Graham Bell and Clarence J Blake’s ear phonautograph, an 1874 curiosity that used an excised human middle ear to visually inscribe sound waves.
The article investigates the construction, reception and fate of a set of models of the Airy Transit Circle (the instrument that defined the Greenwich Prime Meridian) at the Exposition Universelle in 1855 and at the South Kensington Museum.
Through the recent example of the BepiColombo Structural Thermal Model currently on display in the Science Museum, this paper argues that models should be interpreted as original objects and not just as representations of the final product.
