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 https://en.m.wikipedia.org/wiki/Avicenna •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 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.
