   In books like <>   
   by Steve Adams or <> by James   
   H. Smith, they explain how length contraction works. It is in that   
   manner that I think that length of object should be measured.   
      
   In the frame of the object, the length is at rest and measured. In   
   the frame where it is moving, its both ends are noted at the same   
   time.
