作者 王娜 《云南社会科学》 CSSCI 北大核心 2010年第3期43-47,共5页
实验本身和实验室在传统科学哲学框架中并非一个研究重点,实验更多承担着认识论的职责,而实验室则完全被看作是实验进行的物质性场所。但在实验室研究的视野中,实验室成为考察科学的一种新的理论框架,在此框架下,我们得以关注科学知识... 实验本身和实验室在传统科学哲学框架中并非一个研究重点,实验更多承担着认识论的职责,而实验室则完全被看作是实验进行的物质性场所。但在实验室研究的视野中,实验室成为考察科学的一种新的理论框架,在此框架下,我们得以关注科学知识产生的真实时间过程,并由此发现,实验室是一种改变自然与主体之间相关力量的手段,是自然与社会相互塑造的环节。 展开更多

Kenneth Pomeranz and other members of the California School hold that China has lagged behind the West mainly because of the geographical distribution of its mineral resources. They emphasize that the Great Divergence between the East and the West began in very late 1800s. However, the emergence of steam engine, the symbol of the Industrial Revolution, is based on the technology accumulation and inheritance of machine tool industry in 16th century Western Europe. In contrast, China in the Ming Dynasty did not have similar machine tool technologies and even when such Western technologies were introduced to China in the late Ming Dynasty-along with clocks and firearms - they were not successfully grafted into Chinese technology tradition. Therefore, China lacked both the key technologies required for an Industrial Revolution and the capability to develop related technologies. The Great Divergence between the East and the West started in the 16th century and the West's technological capability in the heavy industry is the very advantage that brought it ahead of China. 展开更多
