Egyptian astronomers developed a calendar of 365 days a year. They based this on the annual flooding of the Nile. Also the astronomers noted at which time of the year certain star constellations would appear in sky. This helped them date much of their history.
    Egyptians could also measure areas, volumes, distances, lengths and widths. They used geometry to determined farm boundaries. Their mathematics was based on a system of tens.
    The Egyptians had the first doctors to study the body scientifically. They could set bones, care for wounds and treat many illnesses. Some doctors were specialized in particular fields of medicine. Others specialized in such things like the eyes or the stomach.
