  • Goldbort_Writing for Science

    Although doing science is at the heart of discovery, the effort would have very limited consequence in the long term without writingscience. As a social enterprise that depends on collaboration, scientific inquiry requires its practi- tioners to write on a regular basis. From time to time, some members of the scientific community have been critical of the overall quality of writing by re- searchers.

  • Foundations of Data Science

    Computer science as an academic discipline began in the 1960’s. Emphasis was on programming languages, compilers, operating systems, and the mathematical theory that supported these areas. Courses in theoretical computer science covered finite automata, regular expressions, context-free languages, and computability. In the 1970’s, the study of algorithms was added as an important component of theory. The emphasis was on making computers useful. Today, a fundamental change is taking place and the focus is more on a wealth of applications. There are many reasons for this change. The merging of computing and communications has played an important role. The enhanced ability to observe, collect, and store data in the natural sciences, in commerce, and in other fields calls for a change in our understanding of data and how to handle it in the modern setting. The emergence of the web and social networks as central aspects of daily life presents both opportunities and challenges for theory.

  • 《鏈接:網絡新科學》

    在本書中,作者生動地講述了相互聯系的系統的歷史:從瑞士數學家萊奧哈爾德·歐拉18世紀末對圖論的開創性研究,至現代生物學家基于對細胞網絡的了解而展開的治療癌癥藥物的研究等。本書的思想核心是:鏈接是無處不在的,復雜網絡的本質是無尺度網絡。抓住復雜網絡中的樞紐節點,是我們處理復雜數據的基本原則,也是人工智能背后的深度神經網絡的重要基礎。
