Abu Bakr Muhammed Al-Karaji is a Muslim mathematician and engineer from the late 10th century-early 11th century. Of Persian origin, he spent an important part of his scientific life in Baghdad where he composed ground breaking mathematical books. Al-Karaji is also the author of Inbat al-miyah al-khafiya (The Extraction of Hidden Waters), a technical treatise that reveals such a profound knowledge of hydrology that it should be celebrated as the oldest text of its kind in this field.
