Ibn Sina ī Na (980-1037), the full Arabic name is Abu Ali Hussein bin Abdullah bin Hassan bin Ali bin bin Sina, and the Latin name is Avicenna. He is a great physician, poet, philosopher, and natural scientist of the 11th century, known as the father of world medicine.

Ibn Sina, translated as Ibn Sina in some places or websites, was born near the city of Bukhara, the third largest city in Uzbekistan today. During his youth, he served as a court physician; At the age of twenty, due to the fall of the dynasty, he moved to Hualazimu (a place name in present-day Uzbekistan); Eleven years later, he fled to Persia for political reasons. He is knowledgeable and talented, and has achieved various accomplishments. In medicine, it enriches the knowledge of internal medicine and emphasizes anatomy. The "Medical Dictionary" is the main medical textbook and reference book for Asia and Europe for hundreds of years before the 17th century, so it is called the father of world medicine by people. Philosophically, it is one of the main representatives of the Arab Aristotelian school. Adhering to dualism and creating one's own theory. We acknowledge that the material world is eternal and uncreatable, while also acknowledging that Allah is eternal. Advocating for the immortality and non reincarnation of the soul, opposing the theory of resurrection of the dead. His main works include Treatise on Treatment, Theory of Knowledge, and so on.
Ibn Sina became a philosopher, naturalist, astronomer, mathematician, and was revered as a divine physician. Ibn Sina was born in 980 AD in present-day Tajikistan and is a Tajik. His other name is more widely known: Avicenna. Avicenna began studying basic science and logic at the age of ten. He showed outstanding talent in the field of medicine, and at the age of seventeen, he cured the emperor's illness despite other doctors giving up hope for treatment. From then on, Avicenna's name spread throughout the country. The emperor wanted to reward this little miracle doctor, but Avicena only made one request: to allow him to freely enter and exit the emperor's library. In the eyes of young Avicena, the dusty ancient books in the library are more radiant than gold and diamonds.
As the greatest scholar in the Islamic world, Avicena's interests were too broad. He not only wrote extensively, but also actively participated in the political life of that time, even becoming the prime minister of a country at one point. However, politics is much more complex than science, and Avicenna often escapes from one country to another to evade the pursuit of political enemies. In the end, he died in 1037 AD at the age of 58, which did not match his title as a divine doctor. The reason for Avicenna's premature death was that he worked too hard during his lifetime, engaging in political activities during the day and conducting scientific research at night. His friends suggest that he can live a peaceful and peaceful life, which is beneficial for his physical health. But Avicena replied, "I would rather live a broad and short life than a narrow and long one.".

Regarding the formation of mountain ranges, he believes there are two possibilities: one is the rise of land accompanied by earthquakes, and the other is the erosion of the ground by wind and rain. He proposed that in the long history of Earth, oceans and land have been replaced more than once. Ancient people were passionate about alchemy and fantasized about using cheap metals to make gold. And Avicenna clearly pointed out that metals cannot be converted into each other. This viewpoint was innovative at the time and threatened the livelihoods of some martial artists. His understanding of the properties of metals benefited from in-depth research on minerals. He proposed the classification of rocks and minerals, which was widely spread and has had an impact on modern science.
In the 370th year of the Gregorian calendar, Ibn Sina was born in the city of Bukhara, where he spent the initial stages of his life. At that time, Bukhara scholars and writers gathered and had many large libraries. This academic atmosphere was of great help to Ibn Sina's learning. At that time, his father designated some teachers for him to follow in his studies. He memorized the Quran and studied Arabic and literature before the age of ten.
Ibn Sina was passionate about studying various Greek works. When he was young, he was already proficient in medicine, and many older doctors sought his advice. Patients rushed to him from all directions to seek medical treatment. So he had the opportunity to approach the royal family, and they opened his private library for him, which benefited him greatly in completing his studies and conducting in-depth research.
Ibn Sina is proficient in mathematics, astronomy, physics, philosophy, music, medicine, and logic, and he has many valuable works in these subjects. This is enough to prove that he is a genius. His works were translated into Latin and had a significant impact on the modern European Renaissance.
At the age of twenty, Ibn Sina compiled the famous medical book "The Encyclopedia of Medicine", which was an important reference material in the medical field and translated into dozens of languages. Its Latin translation was reprinted sixteen times in the 15th century, and twenty more times in the 16th century. It remained a textbook for universities in Europe until the late 15th century.

Ibn Sina was the first doctor to discover the presence of parasites in the human body. He has many papers on gastric ulcer, cancer, diabetes, maternal blood flow to the fetus and so on. At the same time, he has also written about pharmaceuticals, herbs, anatomy, nutrition, and other fields. In addition, he has also written about philosophy, logic, literature, astronomy, physics, chemistry, biology, music, and other fields. [1]
Frequent visits to various Islamic countries have enriched his experience and broadened his horizons. He also participates in politics, having held ministerial positions twice, but his political career has not been smooth sailing. He has been imprisoned and threatened with death.
Ibn Sina often goes to the mosque to pray and worship Allah when facing scientific difficulties, hoping that Allah will make the difficulties easier for him. Ibn Sina is not a pessimist, but he is an optimist who dares to face life.
Despite facing various difficulties and frequently migrating from one place to another, he still wrote a large number of valuable works, for which Salton and other Western scholars ranked him among world-class scholars and great Eastern philosophers.
Some Western philosophers say that he is Aristotle and Hippocrates of Islam (Greek physician, 460-359 BC), a world-class scholar proficient in multiple disciplines, with 276 works and papers. "Healing" is one of his most important works, consisting of eighteen volumes, some of which involve logic and natural sciences.
