练乾坤大挪移前学好九阳神功；做论文前学好数学。
求学时代好好学习数学，毕业之后，数学能够不忘记就很不错了，还能精进的很少了。
这是我写的第一篇书评（划掉，不是我写的，转的，作者在开头），我从来没有想过，是写给这样的一本书的。这的确是我迄今最仔细读过的一本书。
在上高一的时候，我就买过一本《数学物理方法》，纯粹出于对书名的崇拜，那还是四川大学出版的那一本。当然，那时的我只能看到Riemann plane就晕得差不多了。那的确是我第一次听说有这样的书存在，数学和物理，好神奇。
Wolves-Selena Gomez-Marshmello
以前有的歌词还翻译一下，现在就基本上都在网上搜一下就行。这首第一句一开始还听错了，blue听成了doom。根据听到（错）的歌词找了一下，这首歌叫做“wolves”
k0
I didn’t know that k0 proposed by Jozsef Jaky (1944) is an analytical result instead of empirical one. In many text books, even including the ** text book, it is presented as an empirical formula.
I doubt that few people actually read the reference from Jaky, ‘ause it is in Hungarian. This is very similar to the case of Reuss (1809), which was published in French.
Nowadays, introduction part of most papers, theses or dissertations, is presented in a way of piling up references without reading any of them. The only purpose is probably to flatter the potential reviewers like “see, I cited your work”.
For work with strong innovation, please be confident enough to refer to “本文不必参考任何文献”（钱伟长，2002） However, in most cases, the authors 怂ed and cited some references like “土力学教材”、“数理方程课本”, in order to be published.
