  you should get the speed of the pulse to be one-fourth of c.
  你测得的相对于脉冲的速度应该是 c/4
• 
  
  But you insist it is c.
  但你坚称测出的仍然是 c
• 
  
  So, what will I say to you?
  那我该对你说啥呢
• 
  
  What will I accuse you of doing?

  And you're finding velocity by finding the distance it travels
  你测速度是通过测量它走过的路程
• 
  
  and dividing by the time
  再除以时间
• 
  
  so you are jacking up a number like c/4 to c itself.
  这样你就会得到一个 介于 c/4 到 c 之间的数
• 
  
  So, what could make you do that? Yep?
  为什么会这样呢 请讲
• 
  
  Yes. So, one option-- Let me repeat what he said.
