Here is a little intro about them and their work to the world of science.All the scientists are before 14th century ..,When you the Europe was called a Dark continent ,Muslims Scientists Were ruling in all over the world! I don't know what happened now But anyways Don't Forget the Past=) Better be Proud!
Muhammad ibn Mūsā al-Khwārizmī
Consequently he is considered to be the father of algebra, a title he shares with Diophantus. Latin translations of his Arithmetic, on the Indian numerals, introduced the decimal positional number system to the Western world in the 12th century. He revised and updated Ptolemy's Geography as well as writing several works on astronomy and astrology.
His contributions not only made a great impact on mathematics, but on language as well. The word algebra is derived from al-jabr, one of the two operations used to solve quadratic equations, as described in his book.

Avicenna was a Persian polymath and the foremost physician and Islamic philosopher of his time. He was also an astronomer, chemist, Hafiz, logician, mathematician, physicist, poet, psychologist, scientist, Sheikh, soldier, statesman and theologian.
His most famous works are The Book of Healing, a vast philosophical and scientific encyclopaedia, and The Canon of Medicine, which was a standard medical text at many Islamic and European universities up until the early 19th century . Ibn Sīnā is regarded as a father of early modern medicine, and clinical pharmacology particularly for his introduction of systematic experimentation and quantification into the study of physiology,] his discovery of the contagious nature of infectious diseases, the introduction of quarantine to limit the spread of contagious diseases, the introduction of experimental medicine, evidence-based medicine, clinical trials, randomized controlled trials, efficacy tests, clinical pharmacology, neuropsychiatry, risk factor analysis, and the idea of a syndrome, and the importance of dietetics and the influence of climate and environment on health. He is also considered the father of the fundamental concept of momentum in physics, and regarded as a pioneer of aromatherapy.
George Sarton,, the father of the history of science, wrote in the Introduction to the History of Science:
"One of the most famous exponents of Muslim universalism and an eminent figure in Islamic learning was Ibn Sina, known in the West as Avicenna (981-1037). For a thousand years he has retained his original renown as one of the greatest thinkers and medical scholars in history. His most important medical works are the Qanun (Canon) and a treatise on Cardiac drugs. The 'Qanun fi-l-Tibb' is an immense encyclopedia of medicine. It contains some of the most illuminating thoughts pertaining to distinction of mediastinitis from pleurisy; contagious nature of phthisis; distribution of diseases by water and soil; careful description of skin troubles; of sexual diseases and perversions; of nervous ailments.
He is "considered by many to be the father of chemistry.
abir Ibn Hayyan is widely credited with the introduction of the experimental method in alchemy, and with the invention of numerous important processes still used in modern chemistry today, such as the syntheses of hydrochloric and nitric acids, distillation, and crystallisation. His original works are highly esoteric and probably coded, though nobody today knows what the code is. On the surface, his alchemical career revolved around an elaborate chemical numerology based on consonants in the Arabic names of substances and the concept of takwin, the artificial creation of life in the alchemical laboratory. Research has also established that oldest text of Jabiran corpus must have originated in the scientific culture of northeastern Persia....
