... and Alex will punch Boris just as strongly as Boris will punch Alex. The only way out of a contradiction is to say that although from Alex’s point of view the velocity of Boris’ fist is smaller than Alex’s, its mass is larger by the same amount, so the momentum of Boris’ fist is the same as the mome ...
