Why are materials, energy and information called the three pillars of modern high technology? What role do they play?

Historically, each era has produced its own unique ideas and concepts, and has given birth to some brilliant sciences that reflect the profound understanding of objective laws at that time, such as materials science, which studies the laws of material structure and motion, and energy science, which studies the laws of energy conversion.

Different from all traditional sciences in the past, information science takes information as the main research object, the law of information movement as the main research content, and the expansion of people's information function, especially intellectual function as the main research goal. In the practice of these studies, it gradually formed its own unique methodology-information science methodology.

With the development of information science, traditional science centered on matter and energy gradually gave way to modern science centered on matter, energy and information.

Information is an independent research object different from matter and energy; It is also an extremely important research object. In a sense, matter, energy and information are indispensable resources for human survival and social development, among which matter and energy are more basic resources, while information is more advanced resources. Material resources provide all kinds of materials for mankind, energy resources provide all kinds of power for mankind, and information resources provide knowledge and wisdom for mankind.
