For hundreds of years, it has grown out of nothing to brilliant performance by several generations of Chinese geologists committing their hearts and minds with the spirit of exert and strive without stop to promote the process of China's industrialization and to produce the significant impact on serving the society. The study of Chinese geosciences history reflects objectively and historically the history of geosciences in China, which has recorded, analyzed and evaluated the dynamic process sitting in the background and clue of the history of Chinese geosciences development. The study of the history of geological science has roughly experienced two stages in China. The first stage is the study of individual researchers. It spanned approximately 70 years from the early 20th century to the end of the 1970s. The research contents were mainly based on the evolution of geological organizations, the development and utilization of individual mineral species, the history of deposit discovery and the research of geological characters. The main representatives are Zhang Hongzhao, Ding Wenjiang, Weng Wenhao and Li Siguang, Ye Liangfu, Huang Jiqing, Yang Zhongjian, Xie Jiarong, Gao Zhenxi, Wang Bingzhang and etc. The most prominent feature of this period is the accumulation of a very valuable document for the study of the history of China's geological history and lays a foundation for the exchange of geological science between China and foreign countries. The second stage is organized group study. It took around 60 years from the 1920s to 1980s. It includes the history of Chinese geology, the history of geological organizations, the history of geological disciplines, the history of geological education, the history of geological philosophy, the history of Chinese and foreign geological science communication, the history of geologists and etc. The most chief feature of this stage is the birth of academic research institute--the establishment of the Commission on the History of Geology of the Geological Society of China.展开更多

Here laboratory animals such as rats, frogs and rabbits were used in medical education to demonstrate physiological principles in the early 1950 s. The establishment of the first animal house in 1969 at UCFM better facilitated the use of laboratory animals in medical education and research. By 2006, lack of ethical guide lines was an issue and a set of ethical guidelines was developed and published in 2009, which today are followed by researchers and reviewers in many universities and research institutions in the country. With this development, there was a need for an organized system of education for the LAS discipline. This was fulfilled by conducting the first certificate course on LAS in the Asian region in 2011 in collaboration with the Utrecht University,Netherlands. The Sri Lanka Association for LAS has continued LAS education since its establishment in 2012 at UCFM by conducting workshops and short courses.展开更多

The particular attention is paid to the interpretation questions and slightly to the aspects, inevitably connected with the world- views of the res- earchers (which do often constitute a part of the interpretation questions).展开更多

The great value of historical materials to modem sciences is explained by citing instances in astronomy, earth sciences and engineering. The importance of the study of the external history of science (i.e. the sociological history of science) to personnel training and policy formulation is stressed. This article also seeks to make clear that the history of science itself is a modern discipline, which has just taken shape in the world during the 20th century, and that the discipline demands prompt development in China in view of its even later start.展开更多
