This all starts in a village, long ago. Humanity was still developing. Most all of civilization revolves around water. In a plain, there is a river. This river is the lifeline to the people there, and produces more than enough water for the whole of the community.
Jahseh was a planner, someone who needs to make sure everything is correct and looked over, because were he to make a mistake and the river malfunction, he could flood a portion of his village.
Jahseh started to plan, he started to think of everything a river extension would need. He knows that the ground was going to resist the flow of the water. So he started to test the soil in the mapped out path. The flow needed to go faster, but first he should make the path.
When Jahseh came back at the end of the day, he started to work on the design of the project a bit more. He needed to see how fast the water would go (Current,) and how much water would need to go through (Voltage,) as well as how much friction the ground would cause and how much water the ground would absorb (Resistance.)
One to smooth out the dirt for allowing water to flow smoother, another to continue digging, and the third group to shave off some more dirt to allow for extra water to come through. The men now had a newfound drive. Feeling much more orderly and motivated with the plan set in place. Work was progressing faster, even though it could take weeks or even months to complete.
Eventually he was finally able to create the river to help out the people in the village. Afterwards he was awarded by his peers that he will save many families and generations to come.
