  • 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.

    • n jerk An involuntary spasmodic contraction of a muscle, due to reflex action resulting from a blow or other external stimulus. Thus, a blow upon the ligament of the patella, below the knee-cap, produces spasmodic contraction of the extensor muscles of the leg, which is straightened with a jerk. This is technically called knee-jerk, and the same action in other parts receives qualifying terms, as chin-jerk, etc.

Reconstructing K-essence
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.
