Mary Somerville (1780-1872) was a Scottish mathematician, astronomer, and writer. She is best known for her work in the fields of mathematics and science, particularly for her contributions to the understanding of celestial mechanics. Somerville's most famous book, *Mechanism of the Heavens*, helped popularize complex scientific ideas and made them accessible to a broader audience. In addition to her scientific achievements, Somerville was a prominent advocate for women's education. She was one of the first women to be elected to the Royal Astronomical Society and played a significant role in promoting the inclusion of women in scientific fields. Her legacy continues to inspire future generations of female scientists.
