Chinese science and technology have interacted with other cultural traditions,both directly and indirectly,for thousands of years.The ongoing discussions of "Silk Road," or rather "Silk Roads" are emblematic of knowledge dissemination and the global connectivity of Chinese society.Modem Chinese science and technology can be understood as the product of practical,technical and theoretical knowledge developments in China,and an exchange with Weste leaing and other knowledge traditions.The distinctive history of Chinese science and technology can help us to understand how science and technology emerges and evolves and how it is communicated in globalization processes.Historical sources and new archaeological discoveries in China have been intensively studied since the beginning of the twentieth century.The results of this research,however,have been published mainly in Chinese,so that the vast majority of results and historical data remain unknown to the inteational community.
