内容简介

想建立自己的物理直觉的物理学学生的基本入门读物

本书以A.Zee的风格呈现，向物理学学生介绍了使用物理推理和明智的猜测来获得问题的核心的做法。作为高年级本科生和其他学生的基本入门读物，《夜航物理学》揭示了研究人员在开始任何计算之前用来思考问题直至解决问题的简单而有效的技术，或者说，如果不能做到这一点，则要聪明地猜测出答案。

在典型的物理学课堂上，学生们试图掌握一个巨大的数学方法工具箱，这是进行物理学中的准确计算所必需的。因此，学生往往会产生一种不幸的印象，认为物理学由定义明确的问题组成，可以通过严密的推理和逻辑步骤来解决。理想化的课本练习和家庭作业问题强化了这种错误的印象。因此，即使是好学生也会发现自己完全没有准备好应对实际研究的挑战。

在现实中，物理学充满了信封式的估计、数量级的猜测和飞跃式的逻辑。本书包括与物理学前沿课题有关的激动人心的问题，从霍金辐射到引力波，这本不可缺少的书将帮助学生更深入地理解他们所学的方程，并培养他们的信心，开始夜以继日地得出他们所寻找的答案。对于教员，可根据要求提供解决方案手册。

The essential primer for physics students who want to build their physical intuition

Presented in A. Zee's incomparably engaging style, this book introduces physics students to the practice of using physical reasoning and judicious guesses to get at the crux of a problem. An essential primer for advanced undergraduates and beyond, Fly by Night Physics reveals the simple and effective techniques that researchers use to think through a problem to its solution-or failing that, to smartly guess the answer-before starting any calculations.

In typical physics classrooms, students seek to master an enormous toolbox of mathematical methods, which are necessary to do the precise calculations used in physics. Consequently, students often develop the unfortunate impression that physics consists of well-defined problems that can be solved with tightly reasoned and logical steps. Idealized textbook exercises and homework problems reinforce this erroneous impression. As a result, even the best students can find themselves completely unprepared for the challenges of doing actual research.

In reality, physics is replete with back of the envelope estimates, order of magnitude guesses, and fly by night leaps of logic. Including exciting problems related to cutting-edge topics in physics, from Hawking radiation to gravity waves, this indispensable book will help students more deeply understand the equations they have learned and develop the confidence to start flying by night to arrive at the answers they seek. For instructors, a solutions manual is available upon request.
