he did not explain the formula in such a way that everyone would understand it.
He said that you must multiply the highest possible speed with the same figure and then multiply it by the amount of mass to see how much energy is involved in the quantity of mass.

Even though the result is correct, I always had difficulty understanding what the highest possible speed multiplied by itself represented.
Had he explained that mass has a surface area that must be represented by squaring the mass figure and then by multiplying the fastest speed that the mass is already experiencing by the square of the mass and then dividing the total by the mass number and multiplying the total with the highest possible speed that the mass can be accelerated to,

 then it will give the total amount of energy that the quantity of mass can possibly have, or had he said to read Genesis and understand it, then it would have been so much easier to grasp the function of the cosmos.

Alternately, he could have given us the formula, E= c*m^2/m*c
