Math has existed for as long as history itself, but female mathematicians become less common the farther back in time you travel. Hypatia of Alexandria is often considered the first known woman in the field. Hypatia: Explorer of Geometry celebrates her adventures as she became one of the Greco-Roman Empire's most notable inventors and teachers over the course of her life. Travel from Lycia to Numidia and all around the Middle East and beyond with Hypatia and her father Theon in this fully illustrated tale of adventure, discovery, and most importantly, math! Hypatia: Explorer of Geometry is the second book in the four part series, STEM Super-heroines, published by Girls Rock Math.
