How to understand that computing is the third method of scientific research .

<> the statement "Computing is the third method of scientific research" refers to the fact that the computational method is an important method in the field of scientific research, along with experiments and theories. Computational methods can provide an effective means of scientific research when experimental and theoretical methods cannot solve the problem or it is difficult to obtain sufficient data. Computational methods have played a key role in breakthroughs in many fields, such as meteorology, astronomy, biology and other fields by means of numerical simulations and numerical calculations.

Therefore, we can consider computing as the third important method of scientific research.

The main research objects of numerical calculation methods are the design, analysis, related mathematical theories and specific implementation of numerical methods for studying various mathematical problems. The iterative method is more commonly used in numerical analysis than the direct method.

For example, such as Newton's method, the dichotomous method, the Jacobian method, the generalized minimum residual method, and the conjugate gradient method, etc. In computational matrix algebra, large problems are often solved using an iterative approach.

In many cases, it is necessary to convert the problem of a continuous model into a problem of a discrete form, and the solution of the discrete form can approximate the solution of the original continuous model, and this transformation process is called discretization.

For example, finding the integral of a function is a problem of a continuous model, that is, if you discretize the area below a curve into a numerical integral, you will be approximating the above area in many simple shapes (such as rectangles, trapezoids), so you only need to add the areas of these shapes.

1. Scientific research methods, philosophical terms, refer to the tools and means to discover new phenomena and new things, or to put forward new theories and new views, and to reveal the internal laws of things.

2. This is the skill of using wisdom for scientific thinking, which generally includes literature investigation method, observation method, speculative method, behavior research method, historical research method, conceptual analysis method, comparative research method, etc. Research methods are constantly summarized and refined in the process of engaging in scientific research. Due to factors such as the perspective of people's understanding of the problem, the complexity of the research object, and the fact that the research methods themselves are in a dynamic development process that constantly influences, combines and transforms each other, it is difficult to have a completely unified understanding of the classification of research methods.
