Muhammad ibn Zakariya al-Razi (Writing)...

His name Razi in Persian means “from the city of Rey”, an ancient town called Ragha in old Persian       The most free-thinking of the major philosophers of Islam, al-Razi was born in Rey, where he was well trained in the Greek sciences. He was well versed in musical theory and performance before becoming a physician. Becoming a Physician, al-Razi  directed two major hospitals, one in Baghdad, the capital of the Islamic empire at that time, and another in his native city of Rayy in northern Iran. His writings on medicine were universally admired.  Razi wrote a pioneering book about smallpox providing clinical characterization of the diseases.”Smallpox appears when blood ‘boils’ and is infected, resulting in vapours being expelled. Thus juvenile blood (which looks like wet extracts appearing on the skin) is being transformed into richer blood, having the color of mature wine. At this stage, smallpox shows up essentially as ‘bubbles found in wine’ – (as blisters) – … this disease can also occur at other times – (meaning: not only during childhood) -. The best thing to do during this first stage is to keep away from it, otherwise this disease might turn into an epidemic.” Al-Razi said. Through translation, his medical works and ideas became known among medieval European and profoundly influenced medical education in the Latin West. Some volumes of his work Al-Mansuri, namely “On Surgery” and “A General Book on Therapy”, became part of the medical curriculum in Western universities. As a teacher of medicine, he attracted students of all backgrounds and interests and was said to be compassionate and devoted. Edward Granville Browne considers him as “probably the greatest and most original of all the physicians, and one of the most prolific as an author....

Ibn Al Haitham

Ibn AL Haitham also known in the Arab world as Alhazen, he was born in 965 in Basra and died in 1040 in Cairo. Ibn Al Haitham was a Muslim mathematician, philosopher, scientists, astronomer and polymath. Ibn Al Haitham made important contributions to the principles of astronomy, optics, scientific method and visual perception. Ibn Al Haitham was the first medical scholar to teach that light “does not originates from the eye but on opposite enters the eye”, which he corrected the Greeks opinion about the nature of the eye. According to Ibn Al Haitham the retina is in the center of the vision and it receives impressions that it transfers to the brain by the optical nerve, for the brain to create visual images for the symmetrical relationship between the retinas. Rosanna Gorini commented on the introduction of the scientific method that Ibn Al Haitham “According to the majority of the historians al-Haitham was the pioneer of the modern scientific method. With his book he changed the meaning of the term optics and established experiments as the norm of proof in the field. His investigations are based not on abstract theories, but on experimental evidences and his experiments were systematic and repeatable”. Roshdi Rashed also wrote about Ibn Al Haitham “His work on optics, which includes a theory of vision and a theory of light, is considered by many to be his most important contribution, setting the scene for developments well into the seventeenth century. His contributions to geometry and number theory go well beyond the archimedean tradition. And by promoting the use of experiments in scientific research, al-Haytham played an important part in setting the scene for modern...
