Of course, Einstein didn't figure out this special principle of relativity in 1905 - it was already done by a guy named Lorentz ten years earlier.

当然，在1905年，爱因斯坦并没有想出这种特殊相对性原则洛伦兹早在10年前就发现了它。

This is the old-fashioned principle of relativity but the point is that the switcheroo changes relative things, like position and velocity, and not absolute ones, like the separation of Einstein from his cat.

这就是早期的相对论但问题是这种平移变换只改变了相对的事物，如位置和速度，而不是绝对的事物，如爱因斯坦和猫之间的距离。

But the principle of relativity has given prominence to the conception of " local time, " and has somewhat diminished men's confidence in the one even-flowing stream of time.

但是相对性原理突出了“本地时间”的概念，并在一定程度上削弱了人们对单一均匀流动的时间流的信心。
