Printed work online
‘Making the arithmometer count’ (1997).
John Dee’s Tyrocinium Mathematicum: new evidence for a lost text. A new source sheds light not only on an obscure work by Dee but also on the composition of his celebrated Mathematicall Praeface to Euclid (1570). A greatly-expanded version will appear in a special issue of Studies in the History and Philosophy of Science Part A in 2012 as ‘John Dee on geometry: texts, teaching and the Euclidean tradition’ [preprint version].
‘Benjamin Martin: London lectures and the 1756 syllabus’, an extension and development of the ‘Benjamin Martin, from beginning to end’ piece listed above, focusing on a Martin lecture syllabus. There are still some remaining puzzles.
William Bourne: a revised bibliography of this Elizabethan mathematical practitioner.
Christ Church Library: Mathematical instruments and architectural space in 18th-century Oxford. A paper given at the Scientific Instrument Commission's XXVIIth Symposium in Lisbon, 16-21 September 2008. The PDF includes the slides from the original Powerpoint presentation along with my informal, spoken notes. Aside from a few typographic corrections the material is as delivered in 2008, with the exception of the 2015 addition of bibliographic and image references at the end, along with a couple of extra notes. With thanks to the Library staff at Christ Church for their assistance and support.
‘Rome revisited: the vertical disc dial’: a do-it-yourself reconstruction of a portable Roman sundial to understand its afternoon operation.
‘History from below: mathematics, instruments and archaeology’: the British Society for the History of Mathematics/Gresham College Annual Lecture 2005, available as text, Powerpoint, audio and even streaming video on the Gresham College website (opens in new window).
‘Jacopo Aconcio’s lost treatise on fortification’: a rediscovered Renaissance manuscript.
‘The astrological instruments of Thomas Hood’: 1998 conference paper.
