Sir Isaac Newton, has originated, inter-conversion of mass and energy,
(E=mc2 )
Newton has stated first of all about inter conversion of mass and
energy. Einstein has derived first mathematical equation for the same.
Newton [1] has quoted in his book ‘Opticks’ in 1704 that
"Gross bodies and light are convertible into one another...",
[ 1 ] Sir Isaac Newton, Opticks, pp. CVX (1704; reprinted by Dover
Publications, Inc., New York, 1952).
After about 200 years Einstein [2] derived mathematical equation for
Newton’s perception i.e. ∆L =∆mc2 where ∆L is light energy emitted
when mass ∆m is annihilated and c is speed of light. It is the rarest
coincidence in between Newton’s hypothesis and Einstein’s mathematical
derivation.
[2] Einstein, A., Annalen der Physik 18, 639 (1905).
Then from ∆L =∆mc2 Einstein speculated ∆E =∆mc2
