The driving force of scientific knowledge is the contradiction between theory and fact: if new acts are not consistent with an established theory, then the search for a new theory that can systematize and explain all the facts becomes an incentive for further development of scientific knowledge. In addition, the development of scientific knowledge is influenced by other factors: continuity, scientific and cultural traditions, the prevailing worldview and even the willful decision of individuals.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
