Sang was the son of Edward Sang, Provost of Kirkcaldy and his wife, Jean Nicol. He was born on 30 January 1805. He attended the Subscription School in Kirkcaldy and from there attended Edinburgh University.
In the 1830s he is listed as a teacher of mathematics living at 32 St Andrew Square in Edinburgh.
He was elected a Fellow of the Royal Society of Edinburgh in May 1836. In 1884 he was awarded their Makdougall-Brisbane Prize. He served as their Vice President 1883 to 1885
In 1841 he took the role of Professor of Mechanical Science at Manchester New College. In 1854 he briefly served as Professor of Mechanical Science in Constantinople. He returned to Edinburgh in 1854 to again teach Mathematics.
He was President of the Royal Scottish Society of the Arts 1857-58.
In 1884 he was elected an Honorary Fellow of the Franklin Institute in Philadelphia.
Sang died at his home, 31 Mayfield Road, Edinburgh Newington on 23 December 1890.
He is buried with his wife and children in Newington Cemetery, Edinburgh. The grave can be found when entering from Dalkeith road, near the cemetery lodge, and then going straight for about 50 meters until meeting a circular plot of graves. Sang's grave is slightly towards the left, on the second circle from the outside. The inscription on the tombplate is
(Elmslie, Nicol, Millar, Wilkie and Chalmers are middle names taken from ancestors' surnames.)
Edward Sang was married to Isabella Elmslie (2 February 1804, Tannadice, Forfar – 24 August 1880) and they had five children:
Anna Wilkie (23 November 1832 – 25 September 1917)
Jane Nicol (16 May 1834 – 9 February 1878)
Edward Elmslie (9 January 1836 – 31 October 1882)
Flora Chalmers (11 May 1838 – 10 May 1925)
Isabella Millar (24 July 1841 – 3 March 1884)
None of the children married.
In 1836, Sang explained how a spinning top could be used to demonstrate the rotation of the Earth, anticipating Foucault's pendulum. (see Johann G. Hagen: La rotation de la terre, ses preuves mécaniques anciennes et nouvelles, 1911)
Trigonometric and logarithmic tables
Sang worked for many years on trigonometric and logarithmic tables. Summaries of his tables were published by Alex Craik.
Sang's 1871 table and his project for a 9-place million table were (re)constructed as part of the LOCOMAT project.
Edward Sang's logarithmic method for constructing a skew arch.
The following list is certainly still incomplete. Some page ranges may be slightly incorrect. Note that Pebble's list of publications contains more items, but some of them seem spurious, and others are not actual publications. Nevertheless, the present list is very likely incomplete.
Communications are marked with "(communication)" and are reviews or summaries of communicated papers. There are many more than those mentioned in the subsequent list.
