It's believed that Hypathia was born in Alexandria and lived between the final periods of the IV century and the beggining of the V century. She was the daughter of a known philosopher, mathematician and an astronomer called Theon, who taught her and developed in her an active attitude towards knowledge, which made her interested in this type of things.

She wrote a Canon of Astronomy, also dedicating herself to the revision of the Astronomical Tables of Claudius Ptolemy, known for their inclusion in the Astronomical Canon of Hesychius. She also mapped various celestial bodies, making a planisphere.

She never got married because she prefered to dedicate her life to the academic work. They describe her as a teacher with a lot of charisma and truly interested in sciences.

Her most extensive work was in algebra. She wrote a commentary on Diophantus Arithmetic (considered as the father of algebra) in which she included alternative solutions and new problems. She also wrote, in eight books, a treatise on the Geometry of the Apollonius Conics (to which the epicycles and deferents are due to explain the irregular orbits of the planets). She collaborated with her father in the revision, improvement and edition of the Elements of Geometry of Euclid, whose edition is still in used today, writing a treatise on it.

In addition to philosophy, mathematics and astronomy, she became interested in mechanics and practical technologies. In the Sinesio Letters are included her designs for several instruments, including a flat astrolabe, that serves to measure the position of the stars, the planets and the Sun. Also she developed an apparatus for the distillation of the water, as well as a hydroscope to Measure the presence and level of water, and a brass graduated hydrometer to determine the specific gravity of the liquids. Finally, she is the inventor of the wind gauge, an instrument used to measure the physical properties of air or other gases.

It is believed that she died violently the 8th of march of 415 D.C. during a christian riot in Alexandria.

-She charted celestial bodies,doing a planisphere,locator of stars and contellations.

Hypatia was very important because she did a lot of interesting discoveries. As we have already said she did big contributions to astronomy and science, including the charting of celestial bodies and the invention of the hydrometer.

She also was important because she did not act like ‘normal’ women at the time, she dressed in the clothing of a scholar or teacher rather than in traditional women's clothes, and drove her own chariot in order to move freely around Egypt.

• She was the only famous woman scholar in ancient Egypt.
• The library where all her work was kept was burned.
• At the age of 45 Hypatia was brutally murdered by a christian mob.
