PRESENT:  "ENERGY IS THE CAPACITY TO DO WORK."

ACTUALLY, WORK IS THE SCATTERING (DISSIPATION)
OF ENERGY.

THE PRESENT DEFINITION STATES THAT "ENERGY IS
THE CAPACITY TO DO SCATTERING OF ENERGY."

ENERGY CAN BE SCATTERED, YIELDING WORK.  BUT
THE CAPACITY TO PERFORM THAT SCATTERING IS
NOT ENERGY!  (E.G., IT MAY BE RESISTANCE.)

COMPARE TO:  "A FISHHOOK IS THE CAPACITY TO
CATCH FISH."

ACTUALLY, A FISHHOOK IS A BENT WIRE WITH A 
BARB.  IT HAS THE CAPACITY TO CATCH FISH (GIVEN
OTHER CONDITIONS).  BUT THE CAPACITY TO CATCH
FISH IS NOT WHAT IT IS.
