Technically that's two pancakes on the bunny's head. E=MC^2 On a side note, anyone know why Einstein picked C^2 (speed of light squared)? Its a little known fact that equation is theoretical at best, and Einstein never meant it to be taken literally. He was just trying to show that energy and mass are related, and that mass has LOTS of energy binding it together (atomically speaking) so he came up with an extremely large number (speed of light) and then squared it to express its an even larger number.

Then this'll hurt more. This is from Jenn..... It deals with the wavelength from a particle of energy, which happens to be synonymous with nuclear energy. All energy posseses momentum and in this case its' momentum is E/c. Einstein assumed that light carries not only momentum and energy, but mass as well. The energy of a particle is proportional to m=Mdelta x/L, where length in L, mass is m and M is the mass of a confined space. Delta t is L/c or time is proportional to Length of box divided by the speed of light, hence the time it takes a particle to travel a length L divided by the speed of light, where light is the particle. It is important to realize the specifications and limitations placed on a particle in a confined space, that particle is threatened only be minimal disturbance and is not able to be tampered with. Delta x can be reduced to EL/Mc^2, E is energy, L is the length of a confined space, M is the mass of the confined space and c is the speed of light. Delta x is momentum by unit time squared or EL/Mc^2, hence M/L * EL/Mc^2 = E/c^2 = m, hence E= mc^2. Otherwise from this any three hundred level physics course can answer subsequant questions!!
