Cartan's construction of (what Slebodzinsky coined as) the "Lie derivative" with
respect to a vector field, V, acting on a 1form, A, is described by Marsden as
Cartan's Magic Formula. (J.E.Marsden & T.S. Ratiu "Introduction to Mechanics
and Symmetry" Springer Verlag 1994 p. 122127)
In the current context, Cartan's magic formula is recognized both as an equation
of topological evolution and as a cohomological equivalent to the First Law of
Thermodynamics.
