Starting around 750 AD, science flourished under the Abbasid caliphs of Baghdad, gradually spreading its influence as far west as Spain and eastwards into Central Asia, over a period of more than 600 years.
By drawing on a variety of texts - Greek, Indian and Persian - and translating them into Arabic, the early scholars accumulated the greatest body of scientific knowledge in the world … and built on it through their own discoveries.
Often, there was a practical Islamic relevance. Astronomy could be used to work out the direction of Mecca for prayer and mathematics was needed for dividing property according to the Islamic law of inheritance.
Although science flourished under Arab-Islamic patronage, by no means all the important figures in science were Muslims, or even Arabs. The common factor, however, was the Arabic language, which for a time became the international language of science.
It was only later, in the 12th and 13th centuries, when the Arabic works began to be translated into Latin, that such knowledge passed to the west.

There is no doubt that Arab civilisation in the Middle Ages made an important contribution to the development of science. These achievements – especially in the fields of astronomy, medicine, chemistry, geography, physics, optics, and mathematics – have tended to be overlooked in the west.
However, attempts to set the record straight are often prone to exaggeration. For example, it is often claimed that in the ninth century Abbas ibn Firnas became the first man to fly. Unfortunately, almost nothing is known for certain about his experiment. The only surviving account of what happened was written by a Moroccan historian some seven centuries later. It said:
"Among other very curious experiments which he made, one is his trying to fly. He covered himself with feathers for the purpose, attached a couple of wings to his body, and, getting on an eminence, flung himself down into the air, when according to the testimony of several trustworthy writers who witnessed the performance, he flew a considerable distance, as if he had been a bird, but, inalightingagain on the place whence he had started, his back was very much hurt, for not knowing that birds when they alight come down upon their tails, he forgot to provide himself with one."
Modern air travellers may not be reassured to know that Baghdad now has an airport named in honour of Ibn Firas.

Science in action
In medieval times the various branches of science were not precisely categorised as they are today. Mathematics and astronomy, for example, were closely related. "Science" also included things that today would be considered un-scientific, such as astrology and alchemy.

Maths in the Early Islamic World[AUDIO]
From the BBC's "In Our Time" series.Melvyn Bragg and guests discuss the flourishing of maths as thinkers from across the region developed ideas in places such as Baghdad's House of Wisdom. Among them were the Persians Omar Khayyam, who worked on equations, and Al-Khwarizmi, who is credited as one of the fathers of algebra, and the Jewish scholar Al-Samawal, who converted to Islam and worked on mathematical induction.

Probably the best introduction to the history of medicine in the Arab world isIslamic Culture and the Medical Arts, which is based around an exhibition held in 1994 to mark the 900th anniversary of the oldest Arabic medical manuscript (pictured on the right) at the National Library of Medicine in the United States. The site, which includes illustrations from old manuscripts, also has suggestions forfurther reading.

Science and Islam today
In 2013, Richard Dawkins, the prominent atheist, caused a furore witha post on Twitterwhich said: "All the world's Muslims have fewer Nobel Prizes than Trinity College, Cambridge. They did great things in the Middle Ages, though."
The implication of his remark was that in modern times, unlike the Middle Ages, there is a link between Islam and scientific under-achievement. Criticspointed outthat the same argument could be applied to all the world's Chinese or even all the world's left-handed people. Conversely, it might be said that Muslim footballers have scored more goals than all the world's Nobel Prize winners put together.
However, what Dawkins said was factually accurate and the real question is to what extent Islam might be blamed for the situation he described. There is little doubt that the authoritarian forms of religion prevailing in the Middle East today do discourage independent thought. The same, broadly speaking, can be said of the societies in predominantly Muslim countries, and of the governments that rule them. But that is by no means the only factor.
It's probably unfair to compare the achievements of Muslims countries with those of the more advanced western countries. It would be better to compare them with non-Muslim countries at a similar stage of development, for example in Africa and Latin America – where the results are unlikely to be very different.
In that connection it's also relevant to consider the effects of foreign conquest. Ziauddin Sardar, a Muslim writer and critic,explained: "In the last two centuries many Muslim countries have been colonised, they have had their resources raped, their institutions of learning closed and their medicine outlawed. In Indonesia, locals were not allowed to go to universities until 1955. How were these people supposed to make discoveries?"
The first person from a Muslim country to win a Nobel prize was the Pakistani physicistAbdus Salamin 1979 – though like many scientists, he worked outside his home country. After graduating at Punjab University, he took a PhD at Cambridge and later became professor of theoretical physics at Imperial College, London.
Egyptian-bornAhmed Zewailwon a Nobel prize for chemistry in 1999, but he was living and working in California.
A lot of scientific research is carried out in the Muslim world, according to Jamil Sherif, secretary of the Muslim Council of Britain's research committee. "At the University of Karachi a lot of work has gone into organic chemistry because the cost of the scientific infrastructure isn't excessive, while a lot of high physics research is problematic, even in Europe," he said.
Universities in the Muslim world are often less well-endowed than in the west. "Historically they have received waqf (Islamic charity) funding but many of these funds have been abolished over the years," Sherif added.
The Arab and Islamic world is also losing talent to the US and Europe. According to the UN Human Development Report of 2003, about 25% of the 300,000 graduates from Arab universities in 1995-1996 migrated abroad.
Science in the Qur'an?
In recent years traditional arguments for a divine origin of the Qur'an have often been supplemented by claims that the Qur'an is a "scientific miracle". The basic idea is that its verses contain information, usually of a scientific nature, that could not have been known to humans in the time of the Prophet – in which case the information must surely have come from God.
Expounding further on this idea, the Institute of Islamic Information and Education says:
"Within the Qur'an are recorded facts about ancient times that were unknown to Muhammad's contemporaries and even to historians in the first half of the 20th century. In scores of verses, we also find references to scientific wonders, some only recently discovered or confirmed, regarding the universe, biology, embryology, astronomy, physics, geography, meteorology, medicine, history, oceanography, etc."
Since the 1980s, the "scientific miracle" of the Qur'an has become a major tool for Islamic proselytising and appears to have met with considerable success. It has also given many Muslims a renewed sense of pride in their religion. In the eyes of others, though, it has done much to discredit Islam.
Islam and evolution
Muslims have generally adopted a positive approach towards science. There is nothing in Islamic history that compares to the battles between church and science in Christianity. However, some Muslims do find it difficult to reconcile the concept of evolution with their faith.
In the 19th century, Charles Darwin’s theory of evolution was given amixed receptionby Muslims: hostility in some quarters and equanimity in others. More recently, however, growing numbers of Muslims have begun to question evolution, often drawing on arguments propagated by Christian Creationists in the United States.
