I just came across this great TED talk by Dr. Helen Czerski, in which she drops the equations for a moment and talks about how physics helps us understand the world we live in.

There is so much about today’s changing world that can make us feel helpless. However, Dr. Czerski suggests that physics provides us with a framework for understanding how things work. With that framework we can get beyond that sense of helplessness and actually have fun exploring our world.
