when we teach classical space time diagrams we measure on the vertical line the dependent space coordinate whereas on the horizontal axis we measure the independent time coordinate in accordance with what we learn say in analytic geometry.(adsbygoogle = window.adsbygoogle || []).push({});

in special relativity we reverse the situation measuring on the horizontal axis the space coordinate and on the vertical one the time coordinate. That is a step not so easy to accept and a switch we should have always in mind. I understand that doing so we ilustrate the absolute character of absolute right and absolute left.are there other advantages as well?
