力学概论

这不像一本普通的力学教材。翻开绪论，作者便以'物理世界的统一'统摄全书，用现代物理的观点重新裁切经典内容——芝诺佯谬、奥伯斯佯谬、牛顿宇宙学这些通常只出现在宇宙学专题里的话题，被前置到入门章节，让初学者在接触牛顿定律之初就望见物理学的纵深。读者反复提及的，正是这种'把前沿拉回课堂'的胆识：它不满足于教人计算，而意在重建一种物理直觉与科学态度——'物理的基础是测量'，规律的建立须以可证伪为前提。它适合那些不甘于把物理当作公式汇编、渴望理解学科内在智慧的人；也适合愿意慢下来、'从普通读到跪'的探索者。

Fang Lizhi (February 12, 1936 – April 6, 2012) was a Chinese astrophysicist, vice-president of the University of Science and Technology of China. After some time at Cambridge University and Princeton, Fang later moved to Tucson, Arizona, where he worked as Professor of Physics at the University of Arizona. In campus speeches Fang spoke on topics such as human rights and democracy as matters of social responsibility. He also served as a board member and co-chair of Human Rights in China. Fang continued to do research in astrophysics and cosmology. He published research papers even during his stay in the US Embassy in Beijing. His later research includes the study of non-Gaussianity in the cosmic microwave background anisotropy, Lyman alpha forest, application of wavelet in cosmology, turbulence in intergalactic medium, and the 21cm radiation during the Reionization. He continued to train students and younger scientists who visited him from China and was very active in research to the end of his life, publishing multiple research papers each year.
