The great heritage of Al Khorezmi

Since a new approach has been developed to the development of education in Uzbekistan, there are many changes in this area today. The qualitative development of education, the training of all-round mature specialists capable of responding to world students, the period itself is more than ever before. Location as noted by Ochildiyev: "The educational reforms carried out on a large scale are subject to the introduction of advanced technologies of education into the process of learning and teaching. In turn, this requires the use and development of pedagogical practice, taking into account the technological approach to the field of education, the acquisition of pedagogical technology and the national, spiritual and cultural characteristics of Uzbekistan, its historical and advanced traditions”[1].

In fact, changing the educational process in a modern way with a productive use of the opportunities created is an indispensable requirement of steam. Therefore, the role of education plays a special role in the worthy position of our state from the world community. The first president of Uzbekistan commented: ”The prospect of our country depends on how our younger generation is brought up, what spiritual qualities it possesses, how active our children are in relation to life, what higher goals it serves " [2]. It is worth noting that the role of national and spiritual heritage created by our ancestors in the upbringing of a mature and harmonious generation in all respects is incomparable.

In particular, Khorezm is a land that has supplied many scientists to the world of Science, and it is about this that P.Tolstov writes: "the role of ancient Khorezm in the history of Oriental Science is very important. We know little about the pre-Islamic antiquity of Khorezm and the afrigian period. But we can say with a thorough analysis of cultural and material monuments that Exact Sciences in Khorezm – geometry, tirigonometry, astronomy, topography, chemistry, mineralogy and Natural Sciences were highly developed at that time... After Khorezm was later included in the Arab Caliphate, Khorezm scientists soon gained fame and took the most advanced place among the creators of Science, which was called ”Arab science”[4]. In itself, it is known that the most important part of the spiritual heritage was created in the Khorezm region, and the role of Muhammad al-Khwarizmi in this heritage plays a special role. His invaluable works, which he created in such fields as mathematics, geometry, astronomy, history, geography, are of particular importance in the upbringing of a harmonious generation at the same time.

In particular, the work "Al-Kitab al-Mukhtasar Fi hesab Al-Jabr and Al-Muqabala", created by the scientist in the development of mathematics, serves as a program-action. As noted by the president of the Republic of Uzbekistan Shavkat Mirziyoyev, “speaking about the great scientists who have grown out of the Khorezm land, we will mention the name Muhammad Khorezmi, who has made an invaluable contribution to the formation of mathematics, trigonometry and geography subjects among the first. This is the first time that our compatriot justified and practiced the decimal position calculation system, the zero sign and the coordinates of the poles”[3]. Also, the largest astronomical work of the scientist has its attention. The scientist wrote this work around 830 year. "Zij"of khorezmi consists of 37 chapters, 116 tables.

The previous five chapters of the work are devoted to chronology, and the rules for the transfer of dates from the "flood", "Alexander", "journey" and Christian eras to the Hijri era are cited. Khorezmiy described the movement of planets based on the geomarcase system of Ptolemy, skillfully using ancient and first medieval Indian Astronomical Data, Iranian and Greek data. Chapter 23 is devoted to trigonometry, in which the Khorezmian introduces the concepts of "flat" and "mirrored sine", and this brings the tables of functions. 25-27 chapters are devoted to mathematical geography. Here, the rules for determining the length and width of geographic areas are cited, and the variation of these coordinates is indicated by the dependence of the sun on the annual, Night-Time motion with changes in the ecliptic, Equatorial coordinates.

In Chapter 28, Khorezmi again addresses trigonometric issues and introduces the concepts of Tangent, kotangens and brings them Moe tables. In Chapter 29, the speed of planetary motion is determined. Chapter 30 presents the measurement of the invisible forces of the sun and the Moon. It turns out that in each chapter of the work a separate problem is revealed, discussed and solved. Therefore, this work of Muhammad al-Khwarizmi was given a high assessment in its time. In particular, Fargani, Al-Hashemi and others from the contemporaries of Khorezmi were highly appreciated. Abu Rayhon Beruni devoted his three works to the interpretation of this "zij". It is our sacred duty of young people to read and study the works of Muhammad al-Khwarizmi, to receive spiritual nourishment from them.

In the cultural heritage, the power that is close to the people's psyche, visibly perceived by the inner instinctive feeling, is hidden. This can be felt only by awake contemplation, sharp perception. Awareness of cultural heritage encourages the human worldview, to think, think and draw conclusions about it.

Historical past will be absorbed into material and spiritual culture. Such cultural values are real facts for historians. Therefore, historical past as a subject of research should be a single norm in historical knowledge, since historical event must necessarily be impartial in assessing processes. Specifically: “selfawareness begins with the knowledge of history. And without knowing the true history, one cannot understand oneself”

In conclusion, it should be noted that the question of attitude to history and understanding of history has risen to the level of Public Policy, and to restore a person and society capable of all reforms through historical thought and historical knowledge, it is also necessary to philosophically observe history. It is necessary to rely on the role of new-minded people in our history, especially potential specialists, and on these issues.
