Small question mark:

The small question mark refers to our ability to ask questions when facing problems. Being good at asking questions is the first step to explore and solve problems. Einstein said, "It is more important to ask a question than to solve it."

Because solving problems may only be a mathematical or experimental skill, but putting forward new problems, new possibilities and looking at old problems from a new angle requires creative imagination, which marks the real progress of science.

Small discovery:

Small discovery means that we discover new phenomena, laws or knowledge through observation, experiment and reasoning in the process of exploring problems. Discovery is the cornerstone of scientific progress.

For example, Newton discovered the law of gravity after being hit by an apple under an apple tree; Watt discovered the principle of steam engine while observing the kettle boiling water. These discoveries have changed our understanding of the world and promoted the progress of human society.

Small exploration:

Small inquiry means that after we find a problem, we explore the essence and law of the problem through scientific methods and means. Inquiry is the soul of science.

For example, after observing the flight of birds, the Wright brothers invented the plane through repeated experimental exploration; Madame Curie discovered radium and polonium while studying radioactive substances. These explorations not only explain the reasons behind the phenomenon, but also provide us with new ideas and methods to solve the problem.

Small creation:

Small creation means that we create new objects, methods or ideas through imagination and creation on the basis of exploring problems. Creation is the life of science.

For example, Edison experienced numerous failures and attempts before inventing the electric light; When Dambert invented the telephone, he succeeded after many experiments and innovations. These creations have changed our way of life and made our life more convenient and beautiful.

In a word, small question mark, small discovery, small inquiry and small creation are the four abilities we should have in our study and life. Only by constantly asking questions, discovering, exploring and innovating can we make continuous progress and development.
