The real meaning of E=MC2
By: R K vanderHoek
This simple equation is the most profound scientific statement about the universe we live in that you will ever learn. With it Einstein takes all existence and reduces it to one thing, energy-mass which composes all matter. Energy-mass is transmutable at a ratio defined by...
