Muslim scientists, the story of Abdurrahman Al-Khazin Brillia

Biography of Abdurrahman Al-Khazin

Abu Al-Fadhl Abdurrahman Ibn Umar Al-Khazin is one of the leading Muslim scientists who lived in the peak of Islamic civilization. Its expertise covers the fields of astronomy, mathematics, and physics. He was estimated to be born in the early 10th century AD in the Khorasan region, which now covered part of Iran, Afghanistan, and Turkmenistan. Although the date of birth was not documented with certainty, historical records mentioned that Al-Khazin died in 971 AD (360 H). During his life, he was under the government of the Abbasid Dynasty and was known as a palace scientist who was in the auspices of the Caliph Al-Muttaqi Billah.

Al-Khazin grew up in a strong intellectual environment and had access to science from previous figures such as Ptolemaeus (Batlamyus), Al-Khwarizmi, and Al-Farghani. He developed his knowledge in the fields of astronomy, mathematics, and physics, and show special interest in scientific experiments. His expertise makes him one of the important figures in the development of scientific methods in Islam.

Contribution of Abdurrahman Al-Khazin to Science Civilization

Although his name is not as popular as Western scientists, Abdurrahman Al-Khazin is one of the Muslim intellectuals from the 10th century whose scientific traces are so deep, especially in the fields of mathematics and astronomy. He lived in the golden age of Islamic civilization, an era in which science became an important part of civilization, not only as a complement to culture, but as the foundation of progress.

The role of al-khazin in the field Mathematics

One of the major contributions of Al-Khazin in the world of mathematics lies in the theory of irrational numbers. Unlike the ancient Greek approach which is still geometric, Al-Khazin tries to understand irrational numbers from the numerical side and algebra. He not only followed Euclid’s theory, but re -interpreted and expanded it through a more analytical approach.

In one of its important works, known as “Book of Mizan Al-Hikmah” (Book of Wisdom Balance), Al-Khazin shows a deep understanding of the structure of numbers, including how to classify irrational numbers, something that is still considered complicated at that time. It even sorts a more flexible explanation Element Euclid’s work makes it easier to apply to practical calculations and the development of algebra that is developing rapidly in the classical Islamic era.

The role of al-khazin in the field Astronomy: Sky as a laboratory

In the field of astronomy, Al-Khazin is known for its diligence in observing celestial bodies and the development of a calendar calculation system. He not only relies on observation data inherited from Greece, but also re-measurement of the planet’s position, the movement of the moon, and compile more accurate parameters for calendar and navigation needs.

Al-Khazin was involved in large scientific projects supported by the palace, including the development of astronomical tables and planetary track calculations. He also corrected small mistakes in the theory of Ptolemaik, and became one of the initial scientists who highlighted the discrepancy between geocentric theory and observation data, he opened the way for critical astronomy discussions in the next era.

Long -term influence and intellectual heritage Abdurrahman Al-Khazin

Al-Khazin’s thoughts and methods turned out to have broad resonance in the world of Islamic and European science. Some of his writings are an important source of references for major scientists such as Ibn al-Haytham, known as the theory of light and optics, Al-Biruni, the Polymath in geodesy and astronomy, to Nasir al-Din al-Tusi, the truster of the tusi-couple model which is the inspiration for Copernicus.

Not only that, some manuscripts by Al-Khazin were copied, translated, and stored in European libraries during the Renaissance. The translation into Latin shows that the knowledge of Muslim scientists not only developed in the Islamic world, but also became an important bridge for the development of modern science in Europe.

Although there is not much information on his spiritual side, Al-Khazin is known as a scientist, humble, and makes knowledge a form of devotion to God. For him, investigating the universe is one form of knowing and approaching the Almighty God.

Al-Khazin’s legacy in Islamic civilization is very large. It is a brilliant example of scientists who not only master the theory, but also apply measurable and rational scientific experiments. Its contribution in physics, mathematics, and astronomy proves that the Islamic world was once the center of world science civilization.
