Water Clock
A water clock or clepsydra (; ; ) is a timepiece by which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel, and where the amount is then measured. Water clocks are one of the oldest time-measuring instruments. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon, Egypt, and Persia around the 16th century BC. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less certain. Some authors, however, claim that water clocks appeared in China as early as 4000 BC. Water clocks were also used in ancient Greece and ancient Rome, described by technical writers such as Ctesibius and Vitruvius. Designs A water clock uses the flow of water to measure time. If viscosity is neglected, the physical principle required to study such clocks is Torricelli's law. There are two types of water clocks: inflow and outflo ...

List Of Inventions In The Medieval Islamic World
The following is a list of inventions made in the medieval Islamic world, especially during the Islamic Golden Age,George Saliba (1994), ''A History of Arabic Astronomy: Planetary Theories During the Golden Age of Islam'', pp. 245, 250, 256–57.

The Islamic Golden Age was a period of cultural, economic and scientific flourishing in the history of Islam, traditionally dated from the eighth century to the fourteenth century, with several contemporary scholars dating the end of the era to the fifteenth or sixteenth century.

A Historical Journal
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Dar Al-Magana
Dar al-Magana () is a 14th-century building in Fes, Morocco, built by the Marinid Sultan Abu Inan Faris which houses a weight-powered water clock. It is located opposite the Bou Inania Madrasa on Tala'a Kebira street and was created to serve that madrasa and its mosque, which was also built by Abu Inan around the same time. The building is also sometimes referred to as the "House of Maimonides" due to a popular legend which claims that the house was once the residence of the famous Jewish philosopher Maimonides. History The clock was part of the large charitable complex centered around the Bou Inania Madrasa built by the Marinid sultan Abu Inan. According to its foundation inscription, construction on the madrasa itself started on December 28, 1350 CE (28 Ramadan 751 AH) and finished in 1355 (756 AH). According to the historical chronicler al-Jazna'i, the water clock was completed on 6 May 1357 (14 Djumada al-awwal, 758 AH). The designer of the clock was a ''muwaqqit'' nam ...
