The Garching nuclear egg: Teaching contemporary history beyond the linguistic turn

In my paper I argue for mobilising recent material heritage at universities in teaching history of contemporary science. Getting your hands dirty in the messy worlds of the laboratory and the storage room, and getting entangled with the commemorative practices of scientists and technicians does not belong to the common experiences of students in history and philosophy of science. Despite the recent material turn in cultural studies, students’ engagement with the material world often remains a linguistic exercise, extending at most to an excursion to the sanitised and academically encultured world of the museum exhibit.I contrast this approach by drawing on experiences of taking students to the Atomei, Germany’s oldest research reactor at the Garching campus of the Munich University of Technology. Decommissioned since 2000, the installation and its history are still controlled by scientists. Studying contemporary laboratories and their materiality has so far been the domain of sociologists and ethnographers. I argue for opening these spaces to historians of science and engaging with the ‘unfinished’ material world of contemporary science. Taking the material seriously beyond the linguistic turn and asking students to explore laboratories and other sites of knowledge production challenges existing histories and historiographies. By exploring local university departments and their recent histories through their material heritage, we can observe everyday science and confront scientists and technicians’ cultures with those of historians’. By engaging with recent material heritage as historians and archivists, students can make an important contribution to enhancing the awareness about this heritage, its implications for history writing, as well as its documentation and preservation.     

How to think about analogical inferences: A reply to Norton

In this paper, I raise some worries with John D. Norton's application of his material theory of induction to the study of analogical inferences. Skeptical that these worries can be properly addressed, I propose a principle to guide the philosophical research on analogical inferences and argue for its usefulness.

浅谈民兵队伍激励机制建设

当前,民兵队伍中普遍存在着物质激励落实力度不够大,精神激励实际效果不明显以及物质激励与精神激励结合不紧密等问题。要想改善这些问题,就必须改善物质激励的方式,以精神激励为主,将物质激励与精神激励有机结合起来,并且充分考虑到民兵的个体差异,才能有针对性的建立一个系统科学、行之有效的激励机制。最后认为运用激励机制必须遵循三个基本原则:实事求是原则、公平合理原则、适时适地原则。     

纯棉水刺非织造材料单向导湿整理工艺的优化

本研究采用含氟拒水整理剂(FG-910)对纯棉水刺非织造材料进行单面整理,使之具有亲疏水双侧结构,从而获得单向导湿功能.经分析可知,影响整理结果的有四个因子:整理液浓度、单位面积使用量、烘干温度和时间以及焙烘温度和时间.对这些因子进行分析,得出最佳整理方案为:整理液浓度40g/L,单位面积使用量为10g/m2,烘干条件为110℃×3min以及焙烘条件为160℃×2min.

时间的过去、现在和未来

本文通过对时间的过去、现在和未来的考证、论述和展望,揭示了先有物质运动滞后才有时间过程,没有物质运动就没有时间过程,时间过程是从表述物质运动过程中产生出来的这一"物质.时间"原理。并且根据这一原理把时间概念定义为:时间是表述物质运动过程的始终和持续性质的物理量。然后,按照这个定义解析了"时空转化"和"时间机器"以及"奇点定理"。认为:既然不存在脱离物质的时间和时间过程,当然也就转化不出或制造不出或证明不了脱离物质的时间和时间过程。因此,这些时间观点都是不能成立的。
