x,y,z,t appear as independent variables in Maxwell's equations. How do we reconcile that with your notion that light is waves of x,y,z,t? Should we read Maxwell's equations upside-down?

How do you read an equation upside-down? I am trying to figure out that transformation : ) Generally we consider equations to be invariant.

Here is the question again. Try answering it.
