This is a dramatic reading of the blog "Deriving How to Derive Field Equations", a blog by the Stand-Up Physicist, available at Science20.com. The next set of five blogs will go into detail about how to derive the Maxwell equations that govern how light works, then do variations on that process to show my efforts to do gravity and unify gravity with Maxwell's work. I do a seven step derivation of the Euler-Lagrange equation, which takes a Lagrange density and generates the field equations.
