Shiing-Shen Chern was a towering figure in mathematics, both for his contributions to differential geometry and as a source of inspiration and encouragement for all mathematicians, and particularly those in China. Born in the final year of the Qing dynasty, and educated at a time when China was only beginning to set up Western-style universities, he lived to preside over the 2002 International Congress of Mathematicians in Beijing. He was a co-founder of the Mathematical Sciences Research Institute in Berkeley and its first Director in 1981; he also set up the Nankai Institute for Mathematics in 1985. His contributions to differential geometry were of foundational importance for the global viewpoint that developed in the postwar years, and the mathematical tools he introduced are now the common currency in geometry, topology and even aspects of theoretical physics.

As is usual, the volumes of Biographical Memoirs contain much material of interest to the student of the mathematical, physical, engineering, biological and medical sciences. Often a memoir has been written in collaboration with another Academy or Society. In the present volume the memoir of Shiing-Shen Chern is an expanded version of an obituary notice by Nigel Hitchin that appeared in the Bulletin of the London Mathematical Society . Chern was a great geometer, who revolutionized differential geometry and whose mathematical tools are now common currency in geometry, topology and theoretical physics. His proof of the Gauss–Bonnet theorem, which was a pivotal event in the history of differential geometry, led to the importance of the Chern classes. Moreover. S.-S. Chern was extremely influential in the development of mathematics and geometry both in the USA, at the Institute of Advanced Study, Princeton, and Chicago and Berkeley, and in China, in Shanghai and Nankei.

The Qing Imperial Academy of Medicine: Its Institutions and the Physicians Shaped by Them

This paper is intended to explain the changes in the activities of the Imperial Academy of Medicine during the Qing dynasty (1644-1911). By tracing its precedents and comparing their functions, I will explain its role during the Qing dynasty. Furthermore, the seemingly hidebound institutional codes in fact reveal interesting information about the dynamics of the Academy. Through examining the impacts of the regulations on personnel and their careers, we are able to explain the very different requirements of the Qing rulers for their medical service. Up until the Ming period (1368-1644) there was an institutional boundary between medical services for the palace and those for the state, even though they shared the same personnel. The Qing was the first dynasty in which even this unclear line disappeared. In this sense, the Qing Academy did not simply copy the tradition of its predecessors. Instead, the services for the emperor’s individual needs became more and more central to its mission. Thus, the common people’s rather critical perceptions of the bureau were largely true. In spite of its increased emphasis on serving the imperial household, the Qing Academy retained its connections with the government. As an alien regime, the Manchu court’s concern for the security of its rulers was much higher than during the previous dynasty. To meet the needs of the new regime, the device of the Qing Academy emphasized fostering elites rather than selecting them. Now the Academy not only provided medical education to the junior members as in earlier periods, but also shaped them in behavior. This affected both the organization of the Imperial Medical Academy, and the strategies of the physicians employed in it.

This chapter draws together the arguments made in the earlier chapters and addresses the question of nationalism, in particular after the Manchu conquest of China and the start of the Qing dynasty in 1644, which altered perceptions of China significantly in East Asia. The cultural pride that developed in Japan, Korea, and Vietnam led to greater interest in the vernaculars but it did not until later lead to a rejection of Sinitic, for until the early twentieth century Sinitic continued to be perceived as the common learned language of the whole of East Asia, rather that the property of China.

AbstractA conference on the interaction of ergodic theory, differential geometry and the theory of Lie Groups was held at the Mathematical Sciences Research Institute from May 24 to June 1, 1984. This is a report of the problem session organized by A. Katok and R. Zimmer and held on May 25, 1984 dealing with the topics in the title. Another problem session was centred on the rigidity of manifolds of non-positive curvature and related topics concerning their geodesic flows. This is reported on by K. Burns and A. Karok separately [2].

In this paper, we analyse features of the grammatical descriptions in Manchu grammar books from the Qing Dynasty. Manchu grammar books exemplify how Chinese scholars gave Chinese names to grammatical concepts in Manchu such as case, conjugation, and derivation which exist in agglutinating languages but not in isolating languages. A thorough examination reveals that Chinese scholarly understanding of Manchu grammar at the time had attained a high degree of sophistication. We conclude that the reason they did not apply modern grammatical concepts until the end of the 19th century was not a lack of ability but because the object of their grammatical descriptions was Chinese, a typical isolating language.

The common watermelon item (Citrullus lanatus) seeds were gained from castoffs verdant nourishments for use by decorating, sun ventilation and pulverizing. Light yellow-toned oil was gotten by dissolvable withdrawal using oil atmosphere and the going with traits were gotten using oil ether: pH, refractive rundown, thickness, dissolvable miscibility, coagulating temperature, fire nature, express gravity, streak point and warmth of consuming. With a shallow level of unsaturation, stepped level of smoothness, and proximity of raised degree of the sensible proportion of free unsaturated fats. The low assessment of the solidifying temperature of the oil offered a hint that the oil can be managed in various areas paying little heed to the qualification in temperature. The following level of linoleic destructive of the oil offers a hint of natural gradation of solidarity. Fatty esters are increasing expanding significance as a biodegradable swap for mineral oils. In some request regions, for example, cutting tool oil, gearbox, pressure-driven oils, and greases for raw petroleum creation, the oleochemical items are set up. Nonetheless, certain particular wellsprings of fatty esters are hitherto to be abused for this comparative reason. This exploration subsequently tests into one of the less used wellsprings of fatty esters in watermelon. The oil from the kernels demonstrations a top-notch yield presents significant utilitarian gatherings for change and thus was utilized to set up an assortment of oleochemicals which demonstrated excellence materials in contrast with the routinely utilized oils feed frameworks for oleochemicals after portrayal. The photopolymers acquired indicated piercing vinyl protons for consistent polymerize.
