Exactly 102 years ago (1905 September 27) Einstein wrote a very short
paper. Einstein starts referring to a body at rest with energy E. I
want to know what kind of energy is that E. Being the body at rest,
the kinetic energy is excluded. Then, what other kind of energy a body
at rest can have in 1905?

The energy that left the body was in the form of radiation. I.e. the
radiation carried away the mass.

Hello Peter. You are right, a little ahead Einstein writes about some
quantity L of light emitted from the body. But I am referring to the
energy E_0 of the body at rest before that. Or you thing that when a
body emits light the energy must be necessary also in light form
before the emission?
