With a civilization of more than 3,200 years, Iran has many scientists and thinkers, and in this text I will mention some of them:

•Avicenna: (known as Abu Ali Sina, Ibn Sina, Porsina and Sheikh al-Raees) omniscient, physician, mathematician, astronomer, physicist, chemist, geographer, geologist, poet, logician, philosopher, musician and Iranian statesman and one of the most famous and influential philosophers and scientists of Iran and the world. It is that It is especially important because of his works in the field of philosophy and medicine. His main works are two comprehensive scientific and philosophical encyclopedias called Kitab Shafa and Ala'i Encyclopaedia, as well as al-Qanun fi al-Tabb as one of the most famous works in the history of medicine

•al-Biruni:Abu Rayhan Muhammad ibn Ahmad al-Biruni (973 – after 1050), known as al-Biruni, was a Khwarazmian Iranian scholar and polymath during the Islamic Golden Age. He has been called variously the "founder of Indology", "Father of Comparative Religion","Father of modern geodesy", and the first anthropologist.

•al-Razi: Abu Bakr al-Razi, often known as (al) Razi or by his Latin name, Rhasis, was an Iranian physician, philosopher, and alchemist who lived during the Golden Age. He is widely regarded as one of the most important figures in the history of medicine, and also wrote on logic, astronomy and grammar. He is also known for his criticism of religion, especially regarding the concepts of prophecy and revelation. However, the religio-philosophical aspects of his thought, which included the belief in five "eternal principles", were recorded only by writers who were often hostile to him.

•Omar Khayyam: was a Persian polymath, known for his contributions to mathematics, astronomy, philosophy, and poetry. He was born in Nishapur.

•Ibn-al-heytham: was a medieval mathematician, astronomer, and physicist of the Islamic Golden Age from present-day Iran. Referred to as "the father of modern optics". he made significant contributions to the principles of optics and visual perception in particular. His most influential work is titled Kitāb al-Manāẓir , written during 1011–1021, which survived in a Latin edition.The works of Alhazen were frequently cited during the scientific revolution by Isaac Newton, Johannes Kepler, Christiaan Huygens, and Galileo Galilei.

•Nasir al-Din al-Tusi: was a Persian polymath, architect, philosopher, physician, scientist, and theologian. Nasir al-Din al-Tusi was a well published author, writing on subjects of math, engineering, prose, and mysticism. Additionally, al-Tusi made several scientific advancements. In astronomy, al-Tusi created very accurate tables of planetary motion, an updated planetary model, and critiques of Ptolemaic astronomy. He also made strides in logic, mathematics but especially trigonometry, biology, and chemistry. Nasir al-Din al-Tusi left behind a great legacy as well. Tusi is widely regarded as one of the greatest scientists of medieval Islam, since he is often considered the creator of trigonometry as a mathematical discipline in its own right.
