With the rapid development of contemporary science and technology, there are an increasing number of disciplines and more detailed divisions of labor. As a method for researching and developing science and technology, it has become increasingly important, evolving to maturity and perfection while forming its own systematic framework—a science that comprehensively reveals the laws of scientific research methods: methodology. The methods of scientific research can be broadly divided into three categories: The first category consists of the most universal research methods applicable to all sciences, namely materialist dialectics and logical methods ； The second category consists of general research methods applicable to natural sciences, such as observation, experimentation, simulation (control), systems, information, and digital methods ； The third category consists of special research methods applicable to certain or one natural science. Based on summarizing and generalizing these three types of basic methods, scientific methodology reveals the essence and laws of operation of scientific research, and establishes the criteria, fundamental theories, and general principles for research methods. It involves knowledge from philosophy, the history of science and technology, geography, creativity studies, psychology, and so on; it is an interdisciplinary field.

In my personal view, methodology is the process of teaching someone how to fish, which is much more advanced than simply giving them fish: lol
