Abu Hamid Ahmed ibn Mohammed al-Saghani al-Asturlabi
(meaning the astrolabe
maker of Saghan, near Merv
) was a Persian astronomer
and historian of science
. He flourished in Baghdad
, where he died in 990 AD.
An inventor and maker of instruments, he worked in Sharaf al-dawla's observatory and, perhaps, constructed the instruments which were used there. Worked on the trisection of the angle.
History of science
Al-Asturlabi wrote some of the earliest comments on the history of science
. These included the following comparison between the "ancients" (including the ancient Babylonians
) and the "modern scholars" (the Muslim scientists
of his time):
