也许正是由于人们总在思考怎样用一个统一时间把不同地方的时间同步化的问题，才激发了爱因斯坦的灵感，产生了相对论，彻底统一了时空问题。
Thinking about how railway time required clocks in different places to be synchronized may have inspired Einstein to develop his theory of relativity, which unifies space and time.
不用爱因斯坦的把握，我们无法理解数学同步于现行轨迹。
One does not need Einstein's grasp of mathematics to understand that we cannot keep pace on our current trajectory.
