Answer:1. Public Libraries
During the early decades of Islam, mosques acted as hubs for intellectual discourse across the Muslim lands. They were not only places of worship, but also housed libraries full of books on religion, philosophy and science. These libraries were open to the masses and not just the ruling and intellectual elite, as was the common practice then.
2. Surgical Tools
The great 10th-century Muslim surgeon Qasim al Zahrawi, described as the father of surgery, invented many surgical tools still used in modern medicine, including the scalpel, the surgical needle and surgical scissors. He also discovered catgut as a reliable material to administer internal stitches as it can be absorbed by the body, preventing the need for a second surgery to remove them.
3. Algebra
The study of algebra flourished during the Islamic Golden Age under the scholarship of mathematician al-Khwarizmi. The word algebra is derived from 'al-jabr', an operation he used to solve quadratic equations. The introduction of algebra as a unifying theory significantly broadened the concept of mathematics and its development path.
