徐光宪对科学理论合理性的评价是从理论概念与物质结构要素的对应、科学理论解释性的强弱等方面进行的。他认为化学学科有独特性,化学反应以及与化学反应相关的分子结构与性质研究,是化学独特的研究对象与问题领域,化学在该领域形成了自己的理论,并不能被还原为物理学。徐光宪用自己的多维分类法对知识进行分类,提出分类的目的是为了做出发现,在研究中亦利用分类进行思维和方法创新。用数学化的方法实现化学研究的精确性,借用模型抽象理论、简化研究程序,综合使用多种仪器设备、将旧仪器引入新领域、拓展仪器的功能,徐光宪为自己的研究需要改进和发明新工具的同时,还为其它研究者提供了便捷有效的工具。 相似文献

The temporal power-law decay is one class of interesting decay processes, usually indicating a long-time correlation and benefiting for a system to perform functions in various time-scales. In this work, I collect the data of the view times versus lectures of some scientific courses on YouTube, according to some special principles. These data can reflect the dynamical property of the spontaneous learning behavior, influenced by the decay of learning interest. The view times versus lectures show an obviously power-law decay process. The power approximates to 1, a universal constant. This finding brings the learning process into the interesting power-law family. It will be of interest in the fields of the human dynamics, psychology and education. 相似文献

There is growing interest in setting up a general concept for quality management and quality control in research and development,
which in this case means, for example, research in the fields of medicine and social sciences. This article is a strong plea
for a quality management system in all fields of research and development and will probably initiate broad discussion on this
delicate topic.

The imbalance between teaching and learning, because of individual difference and the simplicity of teaching, can lead to interest losing on study, which will hinder the further learning. Here, based on the course content, certain scientific software are introduced in chemical laboratory lesson before and after class, thus, students can understand the experimental phenomena with the assistant of this teaching approach. Then laboratory lesson is connected with theory lessons to demonstrate the compounds they synthesized during experiment through a scientific software. The design helps the students understand the role of the software in judging and solving scientific issues. At last, the teaching practice is summarized and reconsidered to point out the essentials in the designing process. 相似文献

Pressing global challenges, such as climate change, the COVID-19 pandemic, or antibiotic resistance, require coordinated international responses guided by evidence-informed decisions. For this purpose, it is critical that scientists engage in providing insights during the decision-making process. However, the mechanisms for the engagement of scientists in policy-making are complex and vary internationally, which often poses significant challenges to their involvement. Herein, we address some of the mechanisms and barriers for scientists to engage in policy-making with a global perspective by early-career scientists. We highlight the importance of scientific academies, societies, universities, and early-career networks as stakeholders and how they can adapt their structures to actively contribute to shaping global policies, with representative examples from chemistry-related disciplines. We showcase the importance of raising awareness, providing resources and training, and leading discussions about connecting emerging scientists with global decision-makers to address societal challenges through policies. 相似文献
