Mary Somerville: The Queen of Science Who Lit Up Edinburgh

Updated: Feb 16

In the quiet Georgian elegance of Northumberland Street, amidst the gas-lit glow of 19th-century Edinburgh, lived a woman whose mind roamed the vastness of the universe. Mary Somerville (1780–1872), the “Queen of Science,” was born into a world that believed women had no place in mathematics or astronomy. But Mary had other ideas.

A Girl Who Would Not Be Silenced

As a child, Mary was told that too much education would harm a girl’s health, leaving her frail and unfeminine. The books were locked away. The tutors dismissed. Instead, she was expected to master the genteel arts—embroidery, music, and the running of a household.

But numbers whispered to Mary. When no one was looking, she taught herself algebra by the light of a candle. When she ran out of books, she learned Greek so she could read the great mathematical texts for herself. Knowledge was her secret rebellion.


Lighting Up the World

Mary’s brilliance could not be contained. She became a leading mathematician, translating and expanding on Laplace’s Celestial Mechanics, a work so complex that few men could understand it. But Mary did. In 1831, she published The Mechanism of the Heavens, a book that became essential reading for Cambridge students.


Her work was more than just theory—it helped predict the existence of Neptune before it was even seen. She wrote about the invisible forces of the universe, years before scientists could prove they existed. In an age when women were denied a university education, here was a woman teaching the greatest minds of her time.


The House Where a Revolution Began

At 53 Northumberland Street, Mary’s mind soared beyond the narrow streets of Edinburgh. Her home was a meeting place for the city’s most radical thinkers—philosophers, scientists, and politicians. Even the great astronomer John Herschel sought her guidance.

Her influence was so profound that when women’s suffrage gained momentum, a petition was presented to Parliament in her name. Oxford University later named Somerville College in her honour, ensuring that the woman who was once barred from education would have a permanent place in its halls.


A Legacy Written in the Stars

Mary Somerville’s name was etched onto the very fabric of the universe—a Martian crater and an asteroid now bear her name. She never saw these distant worlds, but she knew they were there, hidden beyond the limits of human sight, waiting to be discovered.
