foreign loans amounting to 40mil taels were contracted by the Qing government prior to 1890. Science and technology Chinese scholars, court academies, and local officials carried on late Ming dynasty strengths in astronomy, mathematics, and geography, as well as technologies in ceramics, metallurgy, water transport, printing. Contrary to stereotypes in some Western writing, 16th and 17th century Qing dynasty officials and literati eagerly explored the technology and science introduced by Jesuit missionaries. Manchu leaders employed Jesuits to use cannon and gunpowder to great effect in the conquest of China, and the court sponsored their research in astronomy. The aim of these efforts, however, was to reform and improve inherited science and technology, not to replace it. Scientific knowledge advanced during the Qing, but there was not a change in the way this knowledge was organized or the way scientific evidence was defined or its truth tested. Those who studied the physical universe shared their findings with each other and identified themselves as men of science, but they did not have a separate and independent professional role with its own training and advancement. They were still literati. The Opium Wars, however, demonstrated the power of steam engine and military technology that had only recently been put into practice in the West. During the Self-Strengthening Movement of the 1860s and 1870s Confucian officials in several coastal provinces established an industrial base in military technology. The introduction of railroads into China raised questions that were more political than technological. A British company built the Shanghai—Woosung line in 1876, obtaining the land under false pretenses, and it was soon torn up. Court officials feared local public opinion and that railways would help invaders, harm farmlands, and obstruct feng shui. To keep development in Chinese hands, the Qing government borrowed 34 billion taels of silver from foreign lenders for railway construction between 1894 and 1911. As late as 1900, only were in operation, with a further in the planning stage. Finally, of railway was completed. The British and French after 1905 were finally able to open lines to Burma and Vietnam. Protestant missionaries by the 1830s translated and printed Western science and medical textbooks. The textbooks found homes in the rapidly enlarging network of missionary schools, and universities. The textbooks opened learning open possibilities for the small number of Chinese students interested in science, and a very small number interested in technology. After 1900, Japan
