中文简介: | 科学的进步推动了人类社会的发展,在20世纪产生的许多科学成就中,信息论、基因克隆和人工智能形成了戏剧性的革命。然而,人们对科学自身发展的方式却知之甚少。在这项工作中,我们通过分析1900年至2015年间发表的8900万篇数字化论文,研究了过去一个世纪科学发展的演变。我们发现,科学受益于从个人工作到合作努力的转变,本世纪超过90%的世界领先创新是由合作产生的,几乎是20世纪的四倍。我们发现,现代科学家倾向于寻找更远的文献,而不是20世纪初常见的频繁短视和自我参照。最后,我们还观察到从1900年到2015年科学发展的全球化,包括国际合作和引用分别增加了25倍和7倍,以及同期美国、英国和德国引用的主要累积量急剧下降,从95%下降到50%。我们的发现旨在为探索科学在过去一个世纪中以富有远见的方式发展提供开端,从而深入了解当前的科学创新和资助政策并对其产生影响。 |
课程简介: | Progress in science has advanced the development of human society across history, with dramatic revolutions shaped by information theory, genetic cloning, and artificial intelligence, among the many scientific achievements produced in the 20th century. However, the way that science advances itself is much less well-understood. In this work, we study the evolution of scientific development over the past century by presenting an anatomy of 89 million digitalized papers published between 1900 and 2015. We find that science has benefited from the shift from individual work to collaborative effort, with over 90\% of the world-leading innovations generated by collaborations in this century, nearly four times higher than they were in the 1900s. We discover that rather than the frequent myopic- and self-referencing that was common in the early 20th century, modern scientists instead tend to look for literature further back and farther around. Finally, we also observe the globalization of scientific development from 1900 to 2015, including 25-fold and 7-fold increases in international collaborations and citations, respectively, as well as a dramatic decline in the dominant accumulation of citations by the US, the UK, and Germany, from 95\% to 50\% over the same period. Our discoveries are meant to serve as a starter for exploring the visionary ways in which science has developed throughout the past century, generating insight into and an impact upon the current scientific innovations and funding policies. |
