近来,笔者有幸阅读了阎康年同志著的《牛顿的科学发现与科学思想》一书,在受惠于该书的同时,给笔者留下深刻印象的是该书的作者在论述牛顿的科学发现和科学思想时,不是凭二手材料进行简单的推断,而是引用大量的当年牛顿亲笔记录并留存至今的手稿作为佐证,书中的许多观点和论据大多是作者在研究牛顿手稿的基础上总结和归纳出来的。因此,该书的观点是比较客观公正的,如今该书已成为国内有关牛顿研究的经典文献之一,可以说该书及其作者和读者均得益于当年牛顿记录下来的那些手稿。写到这里笔者不由地想起了一则报道,在1987年9月,美国依阿华州立大学图书馆馆长沃伦·B·库恩在河北农业大学图书馆作学术报告时谈到:在大学图书馆中,显得日益重要的部门是收藏部,该机构是收藏学术手稿和珍本图书的中心,该中心在许多学科领域的学术研究 Recently, I was fortunate enough to read Comrade Yan Kang-nian’s book Newton’s Scientific Discovery and Scientific Thought. While benefiting from this book, I was deeply impressed by the author of the book in discussing Newton’s scientific discoveries and Instead of making simple inferences based on second-hand materials, scientific thought quoted a large number of manuscripts that Newton had penned and kept so far as evidence. Many of the ideas and arguments in the book were summarized and summarized by the author on the basis of studying Newton’s manuscripts from. Therefore, the book’s view is more objective and fair. Nowadays this book has become one of the classic literatures about Newtonian research in China. It can be said that the book, its authors and readers all benefit from the manuscripts recorded by Newton that year. Write here I could not help but think of a report, in September 1987, according to Iowa State University Library Director Warren B. Kuhn in Hebei Agricultural University Library for an academic report, said: at the University An increasingly important department in the library is the Department of Collectors, a collection of scholarly manuscripts and books of rare origin, which is a center of academic research in many disciplines
