The technology development process of mankind since modern times is different from that of ancient times. The development of ancient technology is only an occasional event, such as gunpowder, compass, etc. , although it has had a significant impact in military history, due to the simple structure, there is no major improvement in the follow-up. However, modern technology is not, The deployment of machines to steam engines, and then to internal combustion engines, electric motors, and technological progress is continuous and a linear process that can be expected. Therefore, we can aim at the future and make a leap forward in the process. For example, Qian Xuesen's basic industry in China is very weak. , It advocates focusing on the development of missiles instead of aircraft; the United States directly launched the Apollo moon landing program when artificial earth satellites and manned space lag behind the Soviet Union. These are typical examples of leapfrog development. The text is intended to emphasize:. ['Leap-forward development is a prerequisite for seizing the opportunity of technological development.', 'The path of modern technology development is essentially different from ancient times.', 'Courage and courage are the spiritual qualities that support leapfrog development.', 'The infinite pursuit of technological improvement can achieve leapfrog development.']
