What does E=mc^2 mean? How can it be used in an example?

    I was trying to be more clear on how this equation works. I appreciate any help.

    A much better expression is :

    [tex]\Delta E=c^2 \Delta m[/tex]

    The above tells you that even for a very small variation of mass [tex]\Delta m[/tex] one gets a huge variation of energy [tex]\Delta E[/tex] due to the multiplication by the huge number [tex]c^2[/tex].
    As for applications: nuclear power plants.
