  This particular notation has not caught on
  这个特殊的命名没有流行起来
• 
  
  because people are not as interested in what I think as I am.
  是因为大家不会对我的想法太感兴趣
• 
  
  But right now I'm going to call it Fme.
  但现在我还是把它叫做 Fme
• 
  
  I invite you to invent any notation you want
  我推荐你们创建自己喜欢的命名
• 
  
  because there's nothing sacred about a notation,
  因为不用对命名有什么顾忌
• 
  
  at least I want to convey to you that notion.
  至少我想让你们明白这一点
• 
  
  So, I call it Fme, I'm applying to the right,
  所以 我叫它 Fme 方向向右
• 
  
  then I know that it's not moving;
  我知道它没有动
• 
  
  therefore, there has to be another force that cancels it.
  因此 一定还有一个力在对抗这个力
• 
  
  But how much is the other force?
  但是另一个力有多大呢
• 
  
  Yes?
  请讲
• 
  
  That's correct.
  对了
