Einstein is contemplating the equation for the principle that

• mass always travels at the speed of light in a vacuum

• the energy of a photon is proportional to its frequency

• the fundamental source of all energy is the conversion of mass into energy

• energy is emitted or absorbed in discrete packets called photons
