Portait by Thomas Phillips (1834). James Secord is a professor of the history and philosophy of science at the University of Cambridge in the UK. This article is adapted from his book, Visions of Science: Books and Readers at the Dawn of the Victorian Age (2014). Mary Somerville’s vision of science James Secord The Scottish mathematician and writer shaped the way we think about science and carved a place for herself in the intellectual world of the 19th century. n 1834 mathematician and author Mary Somerville published On the Connexion of the Physical Sciences, a work that was instrumental in the making of modern physics as a discipline. Contemporaries praised the book’s clear and lucid Isurvey of astronomy, experimental physics, and chemistry, and it became a classic of Victorian scientific writing. But Connexion also posed key questions for a rapidly expanding and largely male-dominated world at a moment of intense intellectual ferment. Could women excel at science? Were the scientific writings of a woman inherently different from those of a man? “Notwithstanding all the dreams of theorists,” wrote Cambridge philosopher William Whewell in his review of Connexion, “there is a sex in minds”—in other words, Whewell felt that Somerville’s sex would always set her writings apart from those of her male contemporaries.1 During her long life, Somerville occupied an im- taking a prism and a hammer from her handbag to portant place in the physical sciences.
