  • Interesting fact: "Jerkwater" is a railroad term. Until about fifty years ago, most trains were pulled by thirsty steam engines that needed to refill their boilers from water towers next to the tracks. But some towns were so small and inconsequential that they lacked a water tower. When trains stopped in those places, the crew had to find a nearby stream or well and, bucket-brigade style, "jerk" the water to the train. Those little dots on the map became known as jerkwater towns.

When the jerk J e t  vanishes, we have wt   w 0 and one can see that the transformation (1.20) reduces to the Wu transformation (1.14) for a constant-linear-acceleration frame F c x, in which the time axis is everywhere orthogonal to the spatial coordinate curves.
