I mean, all the textbooks

我是说所有的课本
all the novels say,

所有的小说里都是写着
"When I was going down the wrong path,

"我走错了路
then I did a 180." Right?

我转了 180 度" 对吧
So, everyone knows.

大家都知道
In fact, I saw a book by a violinist who said,

其实我看过一本小提琴家写的书中这么说
"I was going down all the wrong things and I did a 360."

"我全都做错了然后我有了 360 度的转变"
So, you realize that

你们也应该发现了
360 is not really a way to reform your life,

360 度的转变其实不算痛改前非
but among the physicists it struck a chord.

但在物理学家看来却意义非凡
In physics, a 360 is really not a trivial thing to do.

物理学里转 360 不是件鸡毛蒜皮的小事
It turns out, the particles in the world

事实上世界上的所有粒子
