Dear “What Good Is”:

What good is physics?  I don’t know where to begin. The movement of the planets and stars are explainable with Newtons Laws of Motion. The nuclear reactions in our Sun and the distant stars explain how they generate energy. Your beating heart is a living embodiment of the physics of fluid dynamics. All need physics principles to explain. Billiards! Tennis!  Golf! Football! Baseball! Physics is everywhere. Just look around you. “Science is a wonderful thing if one does not have to earn a living at it!”
