Physics from Symmetry 2015.pdf

In the course of studying physics I became, like any student of physics, familiar with many fundamental equations and their solu- tions, but I wasn’t really able to see their connection. I was thrilled when I understood that most of them have a com- mon origin: Symmetry. To me, the most beautiful thing in physics is when something incomprehensible, suddenly becomes comprehen- sible, because of a deep explanation. That’s why I fell in love with symmetries. For example, for quite some time I couldn’t really understand spin, which is some kind of curious internal angular momentum that almost all fundamental particles carry. Then I learned that spin is a direct consequence of a symmetry, called Lorentz symmetry, and everything started to make sense.

Physics From Symmetry.pdf

In the two years since the first edition of this book was published I’ve received numerous messages from readers all around the world. I was surprised by this large number of responses and how positive most of them were. Of course, I was cautiously confident that read- ers would like the book. Otherwise I wouldn’t have spent so many months writing it. However, there is certainly no shortage of books on group theory or on the role of symmetries in physics. To quote Predrag Cvitanovic

Waves(physical).pdf

About the series The aim of this series is to discuss the science of various waves. It consists of severalbooks, each covering a specific subject known as a wave phenomenon. Each book isdesigned to be self-contained so that the reader can understand the gist of thesubject. F rom this viewpoint, the reader can read any book as a stand-alone article.However, it is beneficial to read multiple books as it would provide the reader withthe opportunity to view the same aspect of wave dynamics from different angles. The targeted readership is graduate students of the field and engineers whosebackground is similar but different from the subject. Throughout the series, it isintended to help students and engineers deepen their fundamental understanding ofthe subject as wave dynamics. An emphasis is laid on grasping the big picture of eachsubject without dealing with detailed formalism, and yet understanding the practicalaspects of the subject. To this end, mathematical formulations are simplified asmuch as possible and applications to cutting edge research are included. The readeris encouraged to read books cited in each book for further details of the subject.

写给LaTeX2e类与宏包的作者.pdf

本文主要介绍与创作ITpX中的类(class) 与宏包(packages) 相关的事项，特别强调了在将宏包从IATpX 2.09升级至IATpX2e所要注意的事项。关于后者，读者也可以参阅Johannes Braams发表在TUGboat 15.3. 上的文章内容。

使用命令行升级texlive宏包.pdf

如今，很多人（包括我）愿意选择使用镜像文件来安装 texlive。镜像安装虽然有多种好处，但它不可 避免的存在宏包落后的弊端，升级宏包的工作也就摆在了用户面前。 本文简要介绍使用命令行升级 texlive 宏包的几条简单命令。除却命令行，在 windows 系统中还有 Tex Live Manager 桌面应用可以供用户使用来升级宏包，然而这并不是本文所要阐述的内容。

VS Code 配置简介-2019.02.pdf

Visual Studio Code（以下简称 VS Code）是微软推出的一个编辑器，它的优点你可以自行百度，这里 不赘述。对我来说，它最有吸引力的当属在 Windows 系统，它对于中英文字体的渲染。如果你原来用过 其他编辑器，你就知道在普通屏幕上，中英文的显示效果简直是灾难。我原来因为编辑器的中文显示（当 然还有 Terminal 的吸引力）一度想买 Mac，当然最后因为对性能和颜值的追求并不匹配我的财力，加上 Windows 上有些软件不能舍弃，最后作罢。 注：高分屏加上合适的字体，Sublime Text 的显示效果也非常好。

upLaTeX2e入门到劝退（简体）1.4a.pdf

本文专门针对华文纵书（又称垂直排版、直排、竖 排）。日本 upL A T E X2 ε 脱胎于商业排版系统 pT E X ，对 于东亚字体，处理速度远超 X E L A T E X 。惟字体设置是一 大难点。本文从入门到放弃，主要介绍作成者近来使用 upL A T E X2 ε 踏过的坑，和走过的路。
