Hypatia became preeminent mathematics and Alexandria, so, probably the main mathematical world. Invent a new and more efficient method for long divisions. She was also involved in the creation of the astrolabe, a kind of astronomical calculator that was used until the nineteenth century, the hidroscopi, a device for measuring liquid, the hydrometer and aeròmetre

Although all his writings have been lost, There are numerous references to them. His most extensive work was in algebra. He wrote a commentary on Diophantus' Arithmetic (considered the father of algebra) which included the alternative solutions and new problems.

He wrote a Canon of Astronomy, dedicating themselves more to make the revision of the astronomical tables of Ptolemy, known for its inclusion in the Canon Astronomical Hesiquio. He mapped various celestial bodies, making a planisphere.

In addition to philosophy, mathematics and astronomy, was interested in mechanics and practical technologies. In the letters included Sinesi their designs for various instruments, including a plane astrolabe, that serves to measure the position of stars, the planets and the Sun.. He also developed a device for distilling water, as well as a hydroscope to measure the presence and level of water, and a graduate brass hydrometer to determine the specific gravity of liquids. Finally, supposed to be the inventor of aeròmetre, instrument used to measure the physical properties of air or other gases.

As he had frequent interviews with Orestes [the imperial prefect of Alexandria] reported so slanderous between the Christian populace was by his influence that he was prevented from reconciling with Cirilo [the Patriarch of Alexandria]. So, some of them, The ringleader was a reader named Peter, rushed driven by a fierce and fanatical enthusiasm and undertook a conspiracy against him.
