Name: Abu Rihan Mohammad Ibn Ahmad Biruni

In what period of life? In the years 352 to 427 AH

Who was Abu Rihan was a prominent Iranian scientist, mathematician, astronomer, calendarist, anthropologist, and historian in the fourth century AH. Abu Rihan’s father, an astronomer at the court of Khwarezmshah, and his mother were also midwives. Abu Rihan’s father was expelled from the court for jealousy and slander, and then settled in a village around Khorezm. It is said that this is the reason for his fame abroad, because they were strangers to the villagers. Biruni is considered one of the greatest Muslim scholars and one of the greatest Persian-speaking scholars of all time.

What were his scientific achievements? Abu Rihan was one of the first to find the specific gravity of many objects and did so with such precision that the difference between his calculated weights and the weights that scientists have made in recent centuries with respect to all their new devices and technologies is negligible. . Abu Rihan also traveled to various cities during his lifetime and measured the latitude and longitude of those cities and then determined the location of each city on a sphere and after years he was able to map those points on a flat map.

At the age of 17, he observed the solar elevation of the meridian, and one of his most important activities and achievements was the calculation of the radius of the earth, which before him, there was not even an estimate! Abu Rihan is said to have authored about 145 books, for a total of 13,000 pages. More than 90 of them are related to astronomy, mathematics and geological mathematics, but unfortunately over the years, only 35 works by Abu Rihan al-Biruni have survived.

It is also known that in the last hours of Abu Rihan’s life, a person came to see him and he asked him the answer to scientific questions in his bed. Surprised by his work, those around him were wary of scientific discussion; In response, Abu Rihan said: “Is it better to know the answer to this question and die or to die unknowingly?” Abu Rihan al-Biruni died at the age of 78.

An experienced Shiite astronomer and philosopher
Name: Abu Ja’far Muhammad ibn Muhammad ibn

Hassan Tusi known as Khawaja Nasir al-Din

In what period of life? In the years 579 to 653 AH

Who was Iranian poet, philosopher, theologian, jurist, astronomer, thinker, mathematician, astronomer, physician and architect known by such titles as “Nasir al-Din”, “Mohaqeq Tusi”, “Master of Man” and “Khajeh”.

What were his scientific achievements? Tusi revived the tradition of Masha’i philosophy, which had declined in Iran after Ibn Sina. Using Ibn Sina’s philosophical views, he based the Shiite theology on rational arguments and compiled a collection of Shiite theological views and views in the book “Abstraction of Belief”. In the field of astronomy, he built the Maragheh Observatory and next to it created a library that contained nearly 40,000 books.

By raising students such as Qutbuddin Shirazi and gathering Iranian scientists, Tusi became the agent of transferring pre-Mongol Iranian civilization and knowledge to the future. This Shiite scientist has taken a new initiative in observing how to use the sundial, which has been very valuable and lasting in the science of astronomy. Khajeh Nasir al-Din was also one of the developers of the science of trigonometry, whose books on trigonometry were translated into French in the 16th century.


Father of Chemistry
Name: Abu Musa Jaber bin Hayyan

In what period of life? In the years 721 to 815 AH


Who was This great Iranian philosopher has been called the “father of chemistry” and in this regard has had a great impact on alchemists and chemists around the world.

What were his scientific achievements? During his lifetime, Jaber ibn Hayyan made great achievements in the fields of alchemy, astronomy, medicine, philosophy and physics. Examples include some of the laboratory instruments he invented, such as the Anbiq and the Qara. Discovery of many chemicals such as nitric acid, citric acid (lemon essence), acid (among the few substances that dissolve gold), acetic acid (vinegar essence) and the introduction of distillation and crystallization processes, both of which are known as They are considered as the main foundations of modern chemistry, it is one of the scientific achievements of Jaber Binhiyan.


Pharmacist and chemist discoverer of alcohol
Name: Abu Bakr Muhammad ibn Zakaria Razi

In what period of life? In the years 243 to304 AH;

Who was An Iranian physician,

philosopher and chemist who became blind at the end of his life.

What were his scientific achievements? He is best known for his discovery of alcohol. Razi was able to obtain this substance from fermented starches and sugars. He was, of course, the first to discover the chemical substance H2So4 sulfur ink, now called “sulfuric acid.”

His other discoveries in chemistry include hydrochloric acid, which is derived from the effect of lime water on neshadr. Razi also made copper acetate or rust by rubbing vinegar with vinegar to wash wounds. He has also written enduring works in the fields of medicine, chemistry and philosophy. Zechariah also wrote works on cosmology, logic, and mathematics.

This scientist has 56 books in the field of medicine, 33 books in physics, 10 books in the field of mathematics, astronomy, etc. According to George Sarten, the father of the history of science, Razi was the greatest physician in Iran and the Islamic world during the Middle Ages.


Innovator in trigonometry and sinuses
Name: Abulofa Mohammad Bozjani

In what period of life? In the years 319 to 376 AH

Who was He was a great Iranian mathematician and astronomer during the golden age of Islam.

What were his scientific achievements? Bozjani improved the calculation methods used by merchants and criticized some incorrect methods. He proposed methods for making two-dimensional and three-dimensional shapes, adapted from Euclid and Archimedes, and added good initiatives in this area.Before Buzjani, in spherical trigonometry, the only means of solving triangles was Menelaus’ theorem of perfect quadrilaterals, which in Islamic books was called the rule of six values. Buzjani made it easier to solve spherical trigonometry tools by enriching them. In addition, one of the first proofs of the general theorem of sines to solve non-orthogonal triangles was invented by Buzjani.

He solved the unsolvable problems of classical geometry and did research on the principles of geometric drawings, which to date no one has been able to offer another solution to solve those problems. In addition, he was the first to conduct a detailed study of the moon and come up with interesting results that have been proven to be true these days.

Creator of 4 main mathematical operations
Name: Ghiasuddin Jamshid Kashani

In what period of life? In the years 758 to 808 AH

Who was He was the son of a Kashani doctor

named Massoud. He is considered the most


brilliant accountant and the last prominent

mathematician of the Islamic period and one of the greatest figures in the history of Iran.

What were his scientific achievements? In one of his many scientific activities, he completed and corrected the old methods of performing the four main operations of arithmetic and invented new and simpler methods for them. In fact, Kashani should be considered the inventor of the current methods of performing the four main operations of arithmetic (especially multiplication and division). His valuable book, Al-Muftah al-Hesab, is a textbook on basic mathematics, and it is considered to be the best of all medieval mathematical works in terms of abundance, variety of materials, and psychological expression.
