Biography
The birthday of Abu Abdallah al-Khorezmi is not determined yet. He spent his youth in the cities of Khorezm: in Khiva, Zamahshar and Kat, where he was born, lived, studied and also succeeded in many fields of knowledge. The scientist had lived in Khorasan for some time. He achieved the best results and knowledge when he served as katib – the kind of chancellerian (minister’s adviser) to Abul Hasan Ubaydallah ibn Ahmad al-Utbi (977-982). More likely, Al-Khorezmi often used to be in Bukhara for work. He visited emir’s famous library, where he spoke to many great scientists of that time, including, to his junior contemporary, Ibn Sino. He died in 997.
The Main Scientific Works
Al-Khorezmi was an encyclopedic scientist. He created a number of scientific works.
It should be underlined that the only work written by Al-Kharazmi preserved until our times, which had been written in Arabic as the majority of works of that time in Middle Asia, is a treatise “The Keys of Science” (“Mafatih al-ulum”) which is one of the only sources in history of development of sciences and their classification. In “The Keys of Science” consisting of 2 parts Al-Khorezmi expounded the meanings and content of 15 sciences. Chapter One consists of:
Fikkh – the Muslim jurisprudence;

Kalam – the dogmatic theology;
Grammar;
Office Work;
Theory of Poetry and Metrics;
History or Chronological Sciences.
Chapter Two consists of:
Philosophy;

Medicine;
