Other astronomers included ‘Ali Ibn ‘Isa al Astrolabi, from whom we got our term astrolabe, though this instrument for measuring latitude and relative altitude was first invented 300-100 B.C..
Wanajimu wengine ni pamoja na ‘Ali Ibn ‘Isa al Astrolabi, kutokana na huyu tunapata neno astrolabe, japokuwa chombo hiki kwa ajili ya kupima latido na miinuko yenye vipimo sawa kiligunduliwa kwa mara ya kwanza 300-100 KK.
