简明量子场论(第2版)(英文) word 网盘 高速 下载地址大全 免费

这是华裔著名物理学家徐一鸿教授的又一本关于物理学的专著。量子场论是物理学之大成，它融合了狭义相对论和量子力学，是物理学精义的集中体现，也是物理学最艰深的部分之一。许多量子场论的教程，写的晦涩难懂。冗长复杂的数学公式，让物理学的核心思想模糊不清，不知所在。物理学的专业人士，也常常不知所云，更遑论一般读者。而徐一鸿教授的“Quantum Field Theory in a Nutshell”，无论是写作的风格，或者是问题的阐述及处理，都一扫前非。《简明量子场论（第2版）》用略带口语化的语言写成，作者似乎是面对面与你谈论有关的物理学话题。体现作者深刻物理学智慧的内容，俯拾皆是。用最简洁的数学工具，凸显物理学思想，结合轻松幽默的语言，不经意之间，将你引入物理学问题的核心。阅读《简明量子场论（第2版）》给你带来的喜悦，和喜悦之后的收获，似乎只有“The Feynman Lectures on Physics”，与之在伯仲之间。如果想体念和分享，量子场论之美，量子场论之优雅，你不可不读《简明量子场论（第2版）》。
