I'm sure someone can. But I cannot (yet)
I have in front of me the book that Einstein wrote, based on the lectures he gave at Princeton University.
In the Special Relativity presentation, the equation is number 44 and E is written with a 0 subscript because it represents the rest-mass (the mass without the kinetic energy) of the object.
I tried to go backwards to find a suitable starting point to follow his own derivation and I do not find such a point until I make it all the way back to equations 32 and 33, which are special forms of the Maxwell equations (written as partial derivatives in three dimensions).
From this point on, he applies the Lorentz transformation, followed by the vector velocity of electricity and light. Then, in a paragraph titled "Mass and energy" the equations are now in 4 dimensions where the total momentum of a moving object is directly dependant on its initial mass and its speed. When the speed portion is removed, you are still left with the initial rest-mass which, on the Energy side of the equation, is the now famous equation.

Evryone can do it if you study physics you will probably learn how to derive this equation early on your course when you study the Special Theory of relativity.
A nice descriptive page of the derivation can be found at http://www.btinternet.com/~j.doyle/SR/Emc2/Derive.htm . You need to have knowledge of mechanics and calculus to understand it.

His invention of the Atomic Bomb delivered about thousands if not tens of millions of deaths, in Japan in WW2. i imagine he regretted letting the lion out of the container, he suggested that if there replaced right into a WW3 then WW4 ought to by no skill ensue because WW3 ought to obliterate all existence on earth... what a responsibility to bare.. there is not hell yet he did provide an impact it truly is as staggering as a god to simpletons.

E= Mc^2 it is energy of rest of a particle.
M=Ec^2 it is mass of rest of a particle.
It is potential energy/mass of a microparticle (quantum of light).
This potential energy/mass is shown at transition of microparticle
from one condition in another one (kinetic energy).

energy = mass x speed of light squared

The concept was not new to Einstien, the idea had been proposed earlier.
