Connections in physics
Modern differential geometry provides a unified picture for different aspects of physics. In this blog article I would like to introduce three kinds of physical subjects relating to connection on a fibre bundle, namely gauge field, general relativity and theory of quantum Hall effect.

使用 LaTeX 制作音乐文档
因为自学乐理需要写一些 note,我需要使用 LaTeX 编辑含有谱例、音乐记号的音乐文档。常见的选项是 MusiXTeX 包用来制作谱例,musicography 包用来提供正文中的音乐记号。但 MusiXTeX 的语法实在是太反人类了,非常低效,而且不太好看。考虑到 LilyPond 语法比较简单,而且具有导出 midi 文件等强大的功能,我平时单纯打谱也是用它,于是考虑整合 LilyPond 和 LaTeX 成为了一个好的选择。
