In The Beginning: "physics deals with the areas of energy as well as matter. The single scientist who had the greatest impact on the Science of Physics would most certainly be Albert Einstein.
His well known (even if poorly understood) theory of Relativity is often incorrectly stated as E=mc2. My hope is that the theory is rembered this way be cause our keyboards and fonts do not allow to put the little number two above the c.
E (energy)= m (the mass of the given object) times c (a constant which is the speed of light, which is 186,000 miles per second) squared (this huge number is multiplied times itself).
In other words the Energy which is contained within a given object (say a teaspoon) is equal to its weight given in grams times 186,000 x 186,000. Sound like a big number? Yes!"
