Einstein=E2=80=99s mathematical excellence and Newton=E2=80=99s insightful = perception of mass- energy inter conversion (E=3Dmc2)
Einstein [1] derived L =3Dmc2 (Light energy mass inter conversion equation) and speculated E =3Dmc2 in Sep 1905 . But its importance was truly understood in 1920s i.e. at least after
15 years, when NUCLEAR REACTIONS were discovered. Reference of Einstein=E2=80=99s paper is [1] Einstein, A., Annalen der Physik 18, 639 (1905).It pertinent to mention that in derivation of L =3Dmc2 Einstein used an equation of relativistic form of light energy from his June 1905 paper known as Special Theory of Relativity.

Sir Isaac Newton=E2=80=99s perception, two centuries before Einstein.
Einstein was not aware of the fact that, the this equation had been perceived by Newton [1642-1727] in 1704 Newton [2] has quoted in his book =E2=80=98Opticks=E2=80=99 in 1704 that "Gross bodies and light are convertible into one another...",
[ 2 ] Sir Isaac Newton, Opticks, pp. CVX (1704; reprinted by Dover Publications, Inc., New York, 1952). This reflects importance of Newton=E2=80=99s contribution in science.Thus Einstein simply derived equation (L =3Dmc2) for Newton=E2=80=99s 200 y= ears old perception. Then from =E2=88=86L =3D=E2=88=86mc2 Einstein speculated =E2=88=86E =3D= =E2=88=86mc2 Since past over 100 years E=3Dmc2 is being used globally without any exception, however scopes of improvement in every theory always persist.
