Muslim scholars have developed a spectrum of viewpoints on science within the context of Islam. The Quran and Islam allows for much interpretation when it comes to science. Scientists of medieval Muslim civilization (e.g. Ibn al-Haytham) contributed to the new discoveries of science. From the eighth to fifteenth century, Muslim mathematicians and astronomers furthered the development of almost all areas of mathematics. At the same time, concerns have been raised about the lack of scientific literacy in parts of the modern Muslim world.
