A relativistic snake, of proper length 100cm is traveling across a table at V = 0.6c. To tease the snake, a student holds two ends of a cleaver 100cm apart and plans to bounce them simultaneously on so that the left one lands just behind the snake's tail. The student reasons, "the snake is moving with Beta=0.6 so its length is contracted by the factor gamma=5/4 and its length measure in my frame is 80cm. Therefore, the cleaver in my right hand bounces well ahead of the snake, which is unhurt. The snake reasons "the cleavers are approaching me at B=0.6 so the distance between them is contracted to 80cm, and I shall certainly be cut. Use the Lorentz transformation to resolve this paradox.(adsbygoogle = window.adsbygoogle || []).push({});
