Hej!

Det kankse låter konstigt men jag är lite skeptisk till den sajten. Visst har muslimer byggt en stor civilisation. Men man borde vara mer objektiv tycker jag. Den bild som jag fick genom sidan var som om muslimer har uppfunnit allt.

Personlingen nöjer jag mig med en pålitlig historia som berättas av Ibn Khaldun (d. 1406). Här är ett exempell.

Om astronomi

Innovators in astronomy December 21, 2005

Did you know that historians of astronomy often refer to the time from the 8th through the 14th centuries as the Islamic period? As that was when most study of the stars took place in the Muslim world.

The reason for this was in part down to closeness to the Greek world of ancient learning, plus a tolerance for scholars of other beliefs. In the 9th century most of the Greek scientific texts were translated into Arabic. It was through these translations that the Greek works later became known in medieval Europe.

The second push came from the need for people to correctly observe their religious beliefs, which presented a host of problems mostly related to timekeeping. These developments, notably in the field of trigonometry, provided the essential tools for the creation of Western astronomy.

Ibn Khaldun skrev om astronimiska observatorium:

The Greeks occupied themselves very much with astronomical observation. They used instruments that were invented for the observation of the motion of a given star. They called them astrolabes. The technique and theory of how to make them, so that their motion conforms to the motion of the sphere, are a (living) tradition among the people.

In Islam, only very little attention has been paid to astronomical observation. In the days of al-Ma'mun, there was some interest in it. The construction of the instrument known as the astrolabe was begun but was not completed. When al-Ma'mun died, the institution of astronomical observation was lost and neglected. Later on, (scholars) based themselves upon the ancient observations. These were of no use because of the change in the motions (of the stars) over the course of time. The motion of the instrument used in astronomical observations conforms only approximately to the motion of the spheres and the stars and is not absolutely exact. When a certain amount of time has elapsed, the differences are revealed. (slut på citat)



Ur Ibn Khaldun's Prolegomena

Världen behöver en ny generation av muslimer som gör nyttiga saker för mänskligheten istället för att visa vad våra föregångare har lyckats göra, med Guds stöd och hjälp.
