What is creative thinking? We can roughly define it as a materialized ideological and psychological activity with a novel generalization model, which reflects the essential attributes of things and the organic connection between inside and outside. This is the most concentrated embodiment of human wisdom. It enables human beings to break through all kinds of natural limits and create new situations in various fields, thus continuously satisfying human spiritual and material needs.

According to the above definition, creative thinking has the characteristics of initiative, purpose, foresight, seeking the opposite sex, divergence, originality and mutation. It can be positive and negative linear thinking, vertical and horizontal plane thinking, but more importantly, three-dimensional thinking and multi-dimensional spatial thinking. Because of the integrity and intersection of science, the diversity and connection of problems must rely on divergence to converge, even for microscopic scientists. In the past, the study of the flora of the earth has always been a concept of "whole system", without divergent thinking, which led to many nails. Later, the concept of "discrete plate" was put forward. Although it can't be said that all the problems of geologists have been solved once and for all, at the embarrassing moment of traditional geological concepts, the development of earth science has fallen into crisis.

We can classify thinking methods into two types: static, empirical, gradual, regenerative, closed and single passive thinking and dynamic, theoretical, abrupt, variant, open and multi-dimensional creative active thinking.

Among them, creative thinking can be divided into:

? Aggregation thinking

It is characterized by inheritance, reasoning, specificity, rigid development and easy access to micro-discovery.

2. Stereotype thinking

Its characteristics are flattening, openness, plasticity and soft development, and it is easy to realize macro creation.

3. Spatial thinking

It has the characteristics of multi-dimension, openness, jumping and integrity, fully embodies the characteristics of creativity, and is easy to obtain comprehensive and unprecedented ideas and scientific foresight.

The creative process can be roughly divided into the following stages:

1. preparation stage: this is the stage of brewing, presentation, practice and literature research. When Marx wrote Das Kapital, he not only personally participated in the practice of social revolution, but also made study notes on more than 500 books. He studied in the first seat in the last row of the British Museum Library for 25 years.

2. Hypothesis stage: This is the hypothesis stage, which has various positive and negative influences on the research object.
