affairs; it can be
transformed
and or
stored
in many forms, e.g.
solar energy
,
nuclear energy
,
light
,
heat
,
kinetic energy
,
potential energy
, etc.; is the central component in all of
science
, e.g.
chemistry
:
activation energy
,
entropy
,
bond energy
, etc., or
thermodynamics
:
internal energy
,
Gibbs free energy
, etc.; it is equivalent to
mass
:
E=mc

and has its mysteries, e.g.
