物理学研究中交叉学科的演变

The evolution of interdisciplinarity in physics research

Raj Kumar Pan, Sitabhra Sinha, Kimmo Kaski, Jari Saramäki

摘要:

科学作为一项社会事业,容易被分割成专注于专门领域或主题的团体。通常,新的进展是通过子领域之间的思想交叉而产生的,这些子领域在使用不同的技术研究不同的现象时几乎没有重叠。因此,要探索科学进步的性质和动力,就需要考虑不同学科领域之间的大规模组织和相互作用。在这里,我们使用物理学和天文学分类方案(PACS)的代码在过去的25年(1985-2009)发表的文章进行自我分类,研究物理学的子领域之间的关系。我们观察到一个明显的趋势,增加不同的子领域之间的相互作用。子场的网络也表现出核心-外围组织,核心由凝聚态物质和普通物理学主导。然而,随着时间的推移,跨学科物理学在网络核心中的份额稳步增加,反映了物理学研究总体趋势的转变。

英文摘要:

Science, being a social enterprise, is subject to fragmentation into groups that focus on specialized areas or topics. Often new advances occur through cross-fertilization of ideas between sub-fields that otherwise have little overlap as they study dissimilar phenomena using different techniques. Thus to explore the nature and dynamics of scientific progress one needs to consider the large-scale organization and interactions between different subject areas. Here, we study the relationships between the sub-fields of Physics using the Physics and Astronomy Classification Scheme (PACS) codes employed for self-categorization of articles published over the past 25 years (1985-2009). We observe a clear trend towards increasing interactions between the different sub-fields. The network of sub-fields also exhibits core-periphery organization, the nucleus being dominated by Condensed Matter and General Physics. However, over time Interdisciplinary Physics is steadily increasing its share in the network core, reflecting a shift in the overall trend of Physics research.
