A formidable education
Mary Somerville (1780–1872), the Scottish mathematician, astronomer and scientific writer, was born in Jedburgh and brought up in Burntisland, Fife. With little formal schooling, she educated herself largely through independent study, helped by sympathetic relatives and scientific acquaintances. Hers was an extraordinary achievement, though not a solitary one.
Her Mechanism of the Heavens, published in 1831, translated and elaborated upon Laplace’s Mécanique céleste. Its introductory Preliminary Dissertation offered a non-mathematical approach, but the main work required considerable mathematical knowledge. Wider understanding did not, in this instance, mean an easy afternoon’s reading.
The art of making connections
On the Connexion of the Physical Sciences, published in London by John Murray in 1834, more clearly embodied her gift for accessible exposition. Its purpose was to reveal common principles beneath apparently separate branches of science. Rather than presenting knowledge as a collection of compartments, Somerville showed how the compartments communicated.
The book omitted algebraic formulae and explained technical terms. To illuminate sound waves, Somerville invited readers to imagine wind passing over a cornfield: the wave travels onwards while individual ears move locally. A familiar sight thus clarified the distinction between a travelling disturbance and the movement of the material carrying it.
Her dedication also made women’s understanding of natural laws an explicit concern. This was scientific explanation with an educational purpose: demanding ideas were to become more familiar without surrendering their substance.
A readership beyond the study
From September 1837, extracts on sound appeared in the inexpensive Saturday Magazine, reaching readers pursuing self-education. Her Physical Geography, published in 1848, became her most successful textbook and remained in educational use into the early twentieth century.
Somerville also encouraged Ada Lovelace’s mathematical studies and supported women’s education. Oxford’s Somerville College, named after her in 1879, commemorates a legacy encompassing both scientific exposition and women’s intellectual participation.
