The Sons of Musa ibn Shakir

Muhammad, Ahmad, and Al-Hassan, the sons of Musa ibn Shakir, were renowned Persian scientists who flourished in the Arab Caliphate during the 9th and 10th centuries. Their exceptional contributions spanned the fields of geometry, astronomy, and mechanics.

Guardians of Greek Knowledge

The brothers were diligent collectors of Greek manuscripts and established an observatory at the "House of Wisdom" in Baghdad, where they conducted astronomical observations between 850 and 870 AD. Their work was highly regarded by scholars. The renowned astronomer Al-Biruni praised their astronomical tables as superior to others, noting that "they spared no effort in seeking the truth and stood alone in their time in their skill and keenness of observation."

Masters of Geometry and Mechanics

Among their contributions were the translation and annotation of Apollonius' "Conics," the "Book on the Measurement of Plane and Spherical Figures," and the "Book on the Elongated Circle" (which described the construction of an ellipse using the "gardener's method"). They also authored specialized treatises on mechanics, celestial mechanics, and cosmogony, including the "Book on Degrees Concerning the Nature of the Zodiac Signs" and the "Book on the Construction of the Astrolabe."

Legacy and Influence

The brothers' work had a profound impact on subsequent generations of scientists. They were the teachers of the renowned scholar Thabit ibn Qurra, who continued their tradition of scientific inquiry. Their writings and observations laid the groundwork for the advancement of astronomy, mathematics, and other fields, contributing to the flourishing of scientific thought during the Islamic Golden Age.
