The equations of physics are like windows in a large
building. Through each window you can see a little bit of physics. Just as
the windows are not the content of the building, the equations are not the
physics.
As you gain skill at doing mathematics and doing physics
you become able to make your own windows, to see what you want. You come
to understand the world based on what you see through the windows that you
create for yourself.
