Why or how?

I am not sure that we all realized the sutble change that happened around the time we started using mathematics to describe reality. It is very "inter-esting" to suddenly realize that physics is mostly about "how". If the universe works as a clock, with a precise and never-failing rigorous mechanism behind, there is one unambiguous answer to the "how" question.The "why" is very intrincate to answer. Bodies fall, we know how, we can precisely determine the position at all times from initial conditions. To know why they fall...well, I think Feynman does it better than anyone could, watch him in action


...and yet, wouldn't we all agree that our insights all occur when trying to understand the "why" part of the question?
