Techniques of repair, the circulation of knowledge, and environmental transformation: Towards a new history of transportation.

It is the aim of this article to put questions of maintenance and repair in the history of science and technology under scrutiny, with a special focus on technologies and methods of transportation. The history of transportation is a history of trying to avoid shipwrecks and plane crashes. It is also a history of broken masts, worm-eaten hulls, the flat tires of cars, and endless delays at airports. This introductory article assesses the technological, scientific, and cultural implications of repairing and maintaining transportation networks. We argue that infrastructures for maintenance and repair played just as important a role in the history of transportation as the wharves and factories where ships, cars, trains, and airplanes were originally built. We also suggest that maintenance and repair are important sites of knowledge production, and a historical account of these practices provides a new, decentered narrative for the development of modern science and technology.

Making Historical Gyroscopes Alive-2D and 3D Preservations by Sensor Fusion and Open Data Access.

The preservation of cultural heritage assets of all kind is an important task for modern civilizations. This also includes tools and instruments that have been used in the previous decades and centuries. Along with the industrial revolution 200 years ago, mechanical and electrical technologies emerged, together with optical instruments. In the meantime, it is not only museums who showcase these developments, but also companies, universities, and private institutions. Gyroscopes are fascinating instruments with a history dating back 200 years. When J.G.F. Bohnenberger presented his machine to his students in 1810 at the University of Tuebingen, Germany, nobody could have foreseen that this fascinating development would be used for complex orientation and positioning. At the University of Stuttgart, Germany, a collection of 160 exhibits is available and in transition towards their sustainable future. Here, the systems are digitized in 2D, 2.5D, and 3D and are made available for a worldwide community using open access platforms. The technologies being used are computed tomography, computer vision, endoscopy, and photogrammetry. We present a novel workflow for combining voxel representations and colored point clouds, to create digital twins of the physical objects with 0.1 mm precision. This has not yet been investigated and is therefore pioneering work. Advantages and disadvantages are discussed and suggested work for the near future is outlined in this new and challenging field of tech heritage digitization.

Trading zones in a colony: Transcultural techniques at missionary stations in the Dutch East Indies, 1860 - 1940.

Global histories of technology tend to tell one-sided stories of transfer and exploitation, and they usually analyze the activities of large corporations, nation states or the military. By focusing on missionary societies in the colonial era, this article tells a different story. On the basis of primary sources from German missionaries in the Dutch East Indies, it shows how the application of various techniques at missionary stations was the outcome of transcultural interaction. Although missionaries brought with them tools and materials from home, they remained dependent on the knowledge and skills of local artisans, as well as the material and goods the locals provided. Missionaries' wives tried to uphold a Western lifestyle but found themselves using local household technologies. The missionary station was a trading zone: Although the abilities of Europeans and Asians to communicate were socially and linguistically limited, they proved able to exchange information and skills in a successful manner. By revisiting the anthropological background to Galison's trading zone, the authors re-appropriate this concept to improve our understanding of cross-cultural exchange in non-scientific settings.

Reconfiguration, Contestation, and Decline: Conceptualizing Mature Large Technical Systems.

Large technical systems (LTS) are integral to modern lifestyles but arduous to analyze. In this paper, we advance a conceptualization of LTS using the notion of mature "phases," drawing from insights into innovation studies, science and technology studies, political science, the sociology of infrastructure, history of technology, and governance. We begin by defining LTS as a unit of analysis and explaining its conceptual utility and novelty, situating it among other prominent sociotechnical theories. Next, we argue that after LTS have moved through the (overlapping) phases proposed by Thomas Hughes of invention, expansion, growth, momentum, and style, mature LTS undergo the additional (overlapping) phases of reconfiguration, contestation (subject to pressures such as drift and crisis), and eventually stagnation and decline. We illustrate these analytical phases with historical case studies and the conceptual literature, and close by suggesting future research to refine and develop the LTS framework, particularly related to more refined typologies, temporal dimensions, and a broadening of system users. We aim to contribute to theoretical debates about the coevolution of LTS as well as empirical discussions about system-related use, sociotechnical change, and policy-making.

Hackers against technology: Critique and recuperation in technological cycles.

I offer an interpretation of hackers' technological choices through a theoretical framework of critique and recuperation in technological cycles, building on prior research that brings the pragmatic sociology of Boltanski and Chiapello to bear on matters in Science and Technology Studies. I argue that contextualizing technology choices in the development of capitalism through innovation illuminates their political significance. I start with the counterintuitive observation that some browser extensions popular with hackers, like RequestPolicy, make it considerably harder for them to look at websites. This observation showcases the Luddite aspects of hackerdom, in that they are willing to 'break' popular websites that would otherwise cheat on the user. In line with an undercurrent of hacker studies, in this case study I find hackers fighting technological progress they see as social decline.

Iberian science: Reflections and studies.

Over the last two decades early modern historical studies of science, medicine, and technology in the Iberian world have developed into a broad-ranging field with contributions from scholars coming from different historiographical traditions and building upon the solid scholarship of earlier generations. This special issue is an opportunity to explore the field, its recent trends, acknowledge new perspectives that have contributed to the field's growth, and gauge future directions for the field. The six articles offer both reflections on the field's historiography and serve as examples of work currently under way.

Europe's Rhine power: connections, borders, and flows.

This article explores the pivotal position of the river Rhine in the gradual development of a European electricity system. Although the general image of the Rhine is one of a inland transport corridor, it also acted as a backbone of electricity supply systems since the dawn of the 20th century. By relying on insights from both water history and history of technology, the article argues for a transnational approach to better grasp the dynamics of river use and related electricity generation, which often went below, as well as above and beyond nation-state affairs.

Top five medical innovations in China mainland since Xinhai revolution [1911]: results of AME survey-002.

OBJECTIVE: This survey aims to scrutinize important medical innovations in Chinese mainland since Xinhai (Hsin-hai) revolution in 1911, which marked the end of Manchurian imperial rule and the beginning of China's republican era. METHODS: An online cross-sectional survey was carried out during the period of Dec 29, 2014 to Feb 5, 2015, totaling 37 days. The survey was conducted on the platform provided by DXY (www.dxy.cn), which is the largest medical and paramedical related website in China. An email was sent to all DXY registered users to invite them to participate in a 5-minute survey. The participants were asked to nominate up to four important medical innovations in China mainland since Xinhai revolution. The participant could select 'zero' which means he/she felt there was no important medical innovations, or he/she did not know important medical innovations. It was noted that important medical innovations refer to (I) those with practical and almost immediate significance to improve healthcare; (II) should not only be introducing western technique to China, but those involve major improvement of existing western techniques count; (III) should not be those with important theoretical discovery but did not have almost immediate significance to improve healthcare. RESULTS: In total 1,513 DXY users participated in the voting. Totally 489 (32.3%), 441 (29.1%), 342 (22.6%), 150 (9.9%), 91 (6.0%) participants provided 0, 1, 2, 3, 4 nominations respectively. (I) Artemisine (Qinghaosu) for malaria treatment (Project 523 team, 1972); (II) arsenic Trioxide (As2O3) for acute promyelocytic leukemia (APL) treatment (ZHANG Ting-Dong and colleagues, 1970s); (III) limb re-plantation (CHEN Zhong-Wei and colleagues, 1963); (IV) all-trans retinoic acid (ATRA) for APL treatment (WANG Zhen-Yi and colleagues, 1988); and (V) Wu's mask for plague prevention (WU Lien-The, 1910), were voted as the top five innovations in China mainland since Xinhai revolution, with 375, 96, 91, 53, and 8 votes respectively. CONCLUSIONS: In this voting exercise, five achievements were voted as top innovations in China mainland since Xinhai revolution. However, only ATRA for APL treatment was accomplished after the ending of Great Proletarian Cultural Revolution in year 1976 in China.

Frei José Mariano da Conceição Veloso e a divulgação de técnicas industriais no Brasil colonial: discussão de alguns conceitos das ciências químicas / Friar José Mariano da Conceição Veloso and the promotion of industrial techniques in colonial Brazil: discussion of some concepts from the chemical sciences

Na virada para o século XIX, o botânico mineiro frei Veloso desenvolveu intensa atividade de publicação de livros com intuito de divulgar aos colonos do império português técnicas para o melhoramento da produção agrícola e da incipiente indústria química. Este artigo aborda o primeiro tomo da Alographia dos alkalis fixos..., obra que contém artigos, capítulos de livros, cartas e patentes coligidos de uma dezena de autores, especialmente franceses e ingleses, sobre o conhecimento científico e técnico necessário para produção de carbonato de potássio a partir de cinza de plantas autóctones. Alguns conceitos e definições da época da Revolução Química são discutidos, levando em conta como Veloso os traduziu para o português e os introduziu no Brasil por meio de sua obra.

At the turn of the 19th century, Minas Gerais Botanist Friar Veloso worked intensely on the publication of books to promote among settlers from the Portuguese empire techniques for improving agricultural production and from the incipient chemistry industry. This article analyzes the first volume of the "Alographia dos alkalis fixos...", a work that includes articles, book chapters, letters and patents from ten authors, particularly French and English, about the scientific and technical knowledge needed for the production of potassium carbonate from the ash of native plants. Some concepts and definitions used at the time of the Chemical Revolution are discussed, considering that Veloso translated them to Portuguese and introduced them to Brazil through his work.
