Mind mapping, also known as mind mapping, is an effective graphical thinking tool to express divergent thinking. It is simple but effective, and is a practical thinking tool. Mind mapping uses the technique of attaching equal importance to pictures and texts to show the relationship between subjects at all levels with hierarchical maps of mutual subordination and correlation, and to establish memory links between subject keywords, images, colors, etc. Mind mapping makes full use of the functions of the left and right brain, and uses the rules of memory, reading and thinking to help people develop in a balanced way between science and art, logic and imagination, thus opening up the infinite potential of the human brain. Therefore, mind mapping has a powerful function of human thinking. Mind mapping is a method to visualize thinking. We know that radioactive thinking is a natural way of thinking in the human brain. Every kind of data that enters the brain, whether it is feelings, memories or ideas - including words, numbers, symbols, aroma, food, lines, colors, images, rhythms, notes, etc. - can become a thinking center, from which thousands of joints radiate. Each joint represents a connection with the central theme, Each connection can become another central theme, and then radiate thousands of joint points outward, showing a radioactive three-dimensional structure. And the connection of these joints can be regarded as your memory, just like the neurons in the brain are connected to each other, that is, your personal database. Mind mapping, also known as brain map, mind map, brainstorming map, inspiration trigger map, concept map, tree diagram, tree diagram or mind map, is a tool for image based thinking and an auxiliary tool for using image based thinking. Mind mapping is the use of a central keyword or idea to generate visualized structures and classified ideas; It uses a central keyword or idea to connect all the representative words, ideas, tasks or other related projects in a radial linear way.
