The following is a list of inventions made in the medieval Islamic world, especially during the Islamic Golden Age, as well as in later Islamic gunpowder empires such as the Ottoman and Mughal empires.
The Islamic Golden Age was a period of cultural, economic and scientific flourishing in the history of Islam, traditionally dated from the eighth century to the fourteenth century, with several contemporary scholars[who?] dating the end of the era to the fifteenth or sixteenth century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the world's classical knowledge into the Arabic language and subsequently development in various fields of sciences began. Science and technology in the Islamic world adopted and preserved knowledge and technologies from contemporary and earlier civilizations, including Persia, Egypt, India, China, and Greco-Roman antiquity, while making numerous improvements, innovations and inventions.
The most notable medical authors who followed the epoch of the great translators were Persian in nationality but Arab in language: 'Ali al-Tabari, al-Razi, 'Ali ibn-al-'Abbas al-Majusi and ibn-Sina.
Abu Bakr Mohammad Ibn Zakariya al-Razi, known in the West as Rhazes, was born in 865 AD in the ancient city of Rey, Near Tehran. A musician during his youth he became an alchemist. He discovered alcohol and sulfuric acid. He classified substances as plants, organic, and inorganic.
Al-Razi (865–925) was the preeminent Pharmacist and physician of his time . The discovery of alcohol, first to produce acids such as sulfuric acid, writing up extensive notes on diseases such as smallpox and chickenpox, a pioneer in ophthalmology, author of first book on pediatrics, making leading contributions in inorganic and organic chemistry, also the author of several philosophical works.Cite journal requires

However, algebra advanced in other respects. Around 1000, al-Karaji stated the binomial theorem
We wish to construct a pen which can be used for writing without having recourse to an ink-holder and whose ink will be contained inside it. A person can fill it with ink and write whatever he likes. The writer can put it in his sleeve or anywhere he wishes and it will not stain nor will any drop of ink leak out of it. The ink will flow only when there is an intention to write. We are unaware of anyone previously ever constructing (a pen such as this) and an indication of 'penetrating wisdom' to whoever contemplates it and realises its exact significance and purpose. I exclaimed, 'Is this possible?' He replied, 'It is possible if God so wills'.
Three scientists, Ibn al-Haytham, Khayyam and al-Tūsī, had made the most considerable contribution to this branch of geometry whose importance came to be completely recognized only in the 19th century. In essence their propositions concerning the properties of quadrangles which they considered assuming that some of the angles of these figures were acute of obtuse, embodied the first few theorems of the hyperbolic and the elliptic geometries. Their other proposals showed that various geometric statements were equivalent to the Euclidean postulate V. It is extremely important that these scholars established the mutual connection between this postulate and the sum of the angles of a triangle and a quadrangle. By their works on the theory of parallel lines Arab mathematicians directly influenced the relevant investigations of their European counterparts. The first European attempt to prove the postulate on parallel lines – made by Witelo, the Polish scientists of the 13th century, while revising Ibn al-Haytham's Book of Optics (Kitab al-Manazir) – was undoubtedly prompted by Arabic sources. The proofs put forward in the 14th century by the Jewish scholar Levi ben Gerson, who lived in southern France, and by the above-mentioned Alfonso from Spain directly border on Ibn al-Haytham's demonstration. Above, we have demonstrated that Pseudo-Tusi's Exposition of Euclid had stimulated both J. Wallis's and G. Saccheri's studies of the theory of parallel lines.
Ibn Bassal (AD 1038–75) of Al Andalus (Andalusia) pioneered the use of a flywheel mechanism in the noria and saqiya to smooth out the delivery of power from the driving device to the driven machine
The science of medicine has gained a great and extremely important discovery and that is the use of general anaesthetics for surgical operations, and how unique, efficient, and merciful for those who tried it the Muslim anaesthetic was. It was quite different from the drinks the Indians, Romans and Greeks were forcing their patients to have for relief of pain. There had been some allegations to credit this discovery to an Italian or to an Alexandrian, but the truth is and history proves that, the art of using the anaesthetic sponge is a pure Muslim technique, which was not known before. The sponge used to be dipped and left in a mixture prepared from cannabis, opium, hyoscyamus and a plant called Zoan.
