If students don’t understand the history of their nation then they’ll be unable to comprehend what they can do to help build the nation.

Knowing the past provides the necessary knowledge to know what is proper and the wrong. Johannes Kepler , (born December 27th, 1571; Weil der Stadt, Wurttemberg (Germany) – died on November 15th, 1630 in Regensburg), German astronomer who discovered three main laws of motion of planets generally referred to as (1) that the planets rotate through elliptical orbits while keeping the Sun at a single point; (2) the time needed to traverse an circular arc in a planetary orbit can be compared to the surface of the space that lies between it and the circle (the "area laws") and (3) there exists an exact relation with the squares of planets’ regular periods and cubes of the respective mean lengths to each other and the Sun (the "harmonic laws"). This provides us with the chance to make the right decision in the near future.

Kepler himself did not refer to these findings "laws," as would be commonplace following Isaac Newton derived them from a completely different system of fundamental physical concepts. If a person doesn’t understand the history of the past then he will not show any respect to humanity, the country or to the entire world. He saw these as celestial harmonies that were a reflection of God’s plans of the universe. He’ll become an uncaring and selfish person who will not even acknowledge the rich heritage of a nation. Kepler’s discoveries transformed Copernicus’ Sun-centred system into an dynamic universe, with the Sun moving the planets on non-circular orbits. His entire world would look like an automated and programmable system.

Kepler’s concept of physical astronomy theory that resolved a problem that was new to other world-system builders of the online 17th century among which was Newton. Through learning about history, students must be exposed to their nation, culture and their traditions. As well as other accomplishments of Kepler in his work, he offered a fresh and precise explanation of the mechanism behind vision as well as a unique explanation of the behavior of light within the telescope he invented; He discovered new semiregular polyhedrons. This could be an initial step in developing a national spirit in the students themselves.

He also proposed a new theoretical framework for astrology, also limiting the areas in which his predictions could be considered to be reliable. If students don’t understand the history of their nation then they’ll be unable to comprehend what they can do to help build the nation. A listing of his discoveries, however, does not explain how they formed for Kepler the basis of a vast scientific edifice. As an example, if kids do not learn about the history of their nation and are destined to become a future decision maker, they’ll never recognize the importance for their country and will not be able take the appropriate choice. The combination of astrological, theological and physical theories from which Kepler’s discoveries in science were born is fascinating and unique in its individual sense. Furthermore, students who are educated about the past will know how their ancestors fought to establish the independence of their nation. But, given the originality of Kepler’s ideas and the astrological nature of his discoveries, it takes an act of intellectual sensitivity for contemporary scientists to grasp how these long-lasting results could have emerged from such a seemingly inconceivable complexity of ideas.

Therefore, based on this knowledge students may be able to have the motivation needed to build their capabilities in order to be a part of the development of their country both mentally and physically. Although Kepler’s research was focused primarily on astronomy. People who do not have this capacity typically will not be able to contribution to their country. However, the field that was then understood as the study of the movements of stars–was considered to be part of a bigger field of research dubbed "the sciences of the stars." The science of the stars was seen as a mixed field consisting of a mathematical as well as a physical component as well as having the same kinship with other disciplines like musical theory (the study of the ratios between tones) or optics (the study of light).

For example, those living in other countries for a long period of time and are not taught about Indonesian history are likely to never return to Indonesia regardless of the fact that Indonesian society is in need of their contribution. It was further subdivided into both theoretical and practical categories. In conclusion, in light of the these reasons, history knowledge is required by students to help build their nationality and encourage students to make a difference in their nation. Beyond the theory of heavenly motions one could also construct the actual design of planetary tables as well as instruments. Understanding of the past can be the initial step in building the future of tomorrow.

In the same way the theoretical aspects of astrology were accompanied by a practical aspect that involved the production of annual astrological forecasts for cities, people as well as the human body as well as the weather.
