I’m not often mistaken for a scientist, but I do know a few simple laws of physics. Probably the most well-known of these laws tells us for every action, there is an equal and opposite reaction. This law of physics is actually pretty handy when it comes to everyday life.For example, when the Tennessee Vols made the foolhardy decision to hire Derek Dooley as their football coach, there was great sorrow in Knoxville.
