Mathematics is the right-hand man and tool of all sciences. Sometimes it develops due to the promotion of other sciences, and sometimes it develops ahead of schedule. Leading development will eventually be applied. If the development of any science is separated from mathematics, it is impossible to accurately describe the changing state of objective things, let alone deduce the unknown from the known, thus weakening the possibility and accuracy of scientific prediction. Without the infiltration of mathematics into other sciences, human understanding can not really rise to rationality. Mathematics is the link that unites all science and technology, and it will have a strong and far-reaching influence on other disciplines in the past, present and future. With the progress of science and technology, this interaction is more obvious; All science and technology are inseparable from mathematics, and using mathematics to understand problems will have a great impact on the future field of human thought.
