The Light of the Eyes and the Enlightened Landscape of Vision
This work is a noteworthy treatise on optics that covers such basic topics as direct vision, reflection and refraction, and the length of shadows. It discusses convex and concave mirrors and the physiology of vision, and has a section on optical illusions. It is a cogent work on geometrical optics. It is particularly significant because it was written under the Ottoman sulṭān, Murāt ibn Selīm (reigned 1574-95 [982-1003 A.H.]). The name of the author is illegible on the front page, and seems to have been deliberately wiped off for ...

A Guide to Geometry, Surveying, the Launching of Missiles, and the Planting of Mines
This work, primarily intended for the training of military men, is a translation from a number of sources originally written in German and French. It was presented to the Bureau of Warfare and Jihād (Dār al-naṣr wa al-jihād) in Muḥarram, AH 1193 (early winter, 1779), or nearly two decades before Napoleon’s invasion of Egypt in 1798. The work’s compiler, ʻUthman ibn ʻAbd al-Mannān, a translator at the Ottoman court in Belgrade, had converted to Islam from Christianity. The title of the work hints at his sincere effort to ...

Works of Galileo Galilei, Part 2, Volume 13, Floats: Fragments and First Drafts Related to the Treatise "Of Things that Float on Water"
This fragmentary work elaborates on earlier studies undertaken by the Italian scientist, philosopher, and mathematician Galileo Galilei (1564–1642) on the Greek mathematician and physicist Archimedes of Syracuse (circa 287 BCE–circa 212 BCE). This study contains notes about the theories of buoyancy and floatation, which Galileo later gathered in a more coherent form in his treatise Discorso… intorno alle cose che stanno in sù l’acqua (Discourse on floating bodies), published in Florence in 1612. As with his more prominent work of astronomy, Sidereus Nuncius (Starry messenger), Galileo’s ...

Smoothing the Basis for the Investigation of the Meaning of Transits
Abu al-Rayhan al-Biruni (also known by the Latinized version of his name, Alberonius, 973–1048 AD; 362–440 AH) was an 11th-century Muslim polymath whose works and scholarly interests spanned the physical and natural sciences, mathematics, astronomy, geography, history, chronology, and linguistics. Al-Biruni was born in Kath, Khuwarazm, in present-day Uzbekistan, and died in Ghazni, in what is today east-central Afghanistan. He wrote more than 120 works and is considered the founder of Indology for his detailed description of 11th-century India. The crater Al-Biruni on the moon is named after ...
