Review on Needham Puzzle

In Needham Puzzle,that the ancient Chinese science and technology had declined in certain period has never been mentioned,but it said that compared with the age before the 15th century,the ancient Chinese science and technology had developed slowly.No matter under what kind of significance,the Needham Puzzle is tenable.It consists two parts,which is parallel and without any logically necessary association.Hence,resolving Needham Puzzle is unlike dealing with other propositions.As the nomadic minority occupied Central Plains and reined China and the peasant uprising caused dynastic change,the modern science and technology had not appeared in China.In the post-Needham age,Chinese people should follow the rule of Chinese scientific and technical development,creating conditions to exceed Needham Age.
