Scientific Arguments
A friend of mine in high school was a year older and the summer he got his license was good times. He always had at his disposal a blue Dodge minivan that we could use and abuse. One thing that we derived hours of amusement from was to drive around town with the side door slid open and shoot at the school with one of those high powered wristrocket slingshots with the surgical tubing. Our object was to take out one of the big windows at the front, but it always seemed that Newtonian Physics or the Hand of God would steer the steel ball away from the glass within the last 15 feet or so of the trajectory. Being dumb, we had no idea what scientific principles were at play. Why was our missile not hitting its intended target? How could we overcome the prevailing vectors that had prevented successful take down? One theory that my friend proposed was that since the car was involved, its own forward speed and momentum was tied up somehow in all of this. He dubbed it The Doppler Effect. Another friend who was often in the van and who was a bit smarter than us expressed his adamant opposition to this proposed theory. "It is not the Doppler Effect!" he would shout. Having come to no agreement on the subject cause and effect we got the hell out of there and went to get fast food.
