Muslim world has produced great scientist who had made remarkable contribution to science and technology.Due to their tireless and valuable research,they provided a stronger foundation to the present day  science and technology.Among the galaxy of Muslim Scientist,one shinning star was Abu Ali Hussain Ibn-e-Abdullah Ibn-e-Sina.He was born 980 in AD at Afsana near Bukhara (Central Asia) and died in Hamdan in 1047.He is a true product of Muslim civilization in its climax of scientific growth.His contribution to the world of science was enormous.

It was just around the time of Ibn Sina 's birth and in the subsequent years that Islamic Arabic culture reached its peak.Since the Arabic language was the accepted vehicle for the transmission of knowledge in this era,Ibn-e-Sina studied Arabic under Abu Bakr Ahmad bin.Muhammad al-Khwarizmi.As soon as he had mastered Arabic ( his mother tongue was Persian), his father arranged for him a teacher of the Quran and another for literature.The young pupil learned quickly from his two teachers,and before he was 10 years old,he knew the Qur'an and a considerable amount of literature.Next he developed a leaning towards philosophy,geometry and mathematics.He was then attracted by the medical science,and devoted himself to it for a brief time,until he surpassed all the scholars of his age in this science.
Nuh bin Mansur Samani was the ruler of Bukhara at that time.He was affected by a disease physicians failed to cure.Ibn-e-Sina was by then a well-known scientist and physician.The Physicians mentioned him to Nuh bin Mansur as a skilful physician and asked to call Ibn-e-Sina to the court.
Ibn-e-Sina visited Nuh bin Mansur and contributed to his treatment,and since then he became very close to the ruler of Bukhara.Ibn-e-Sina asked Nuh bin Mansur to give him permission to enter his great,well-know libraries.The ruler gave him the permission,and Ibn -e-Sina found many great books there some of which he even never heard of.
He started reading the books and learned  a lot from them.At this time Ibn-e- Sina was 18 years old and had learned all branches of knowledge in his time.He later said,"I had a better memory then;my stock of knowledge now is the still the same,but my knowledge is now more exact."
Ibn Sina 's most famous works are those on philosophy and medicine.His philosophical views have engaged the attention of Western thinkers over several centuries,and his books have been among the most important sources in philosophy.In medicine,his great work,al Qanun (The Canon),was translated into Latin towards the end of the twelfth century and became a reference source for medical studies in the universities of Europe until the end of the seventeenth century.
Ibn-e-Sina,the great scientist of his time,has some original contribution to his credit, he for the first time detected the contagious nature of tuberculosis and diseases spread by water and close relationship between psychology and health.This man further added feather to his cap by doing work on anatomy and child health.He was pioneer scientist in describing the minute and graphic description of different parts of body.His other great work,"Kitab-Al-Shifa",a philosophical encyclopedia cannot be overlooked.This book has covered a wide range of fields like philosophy,science,physics,mathematics,metaphysics,ethics,economics and politics.He is remembered for his discoveries in physics.He discussed inter-relationship between time and motion.

His contribution to the fields of geography and chemistry has great importance as well.
