Quote: E= m c^2, i.e., mass and energy are essentially alike

Quotation

If we apply the last of equations ... to a material particle at rest (q=0), we see that the energy, E_0, of a body at rest is equal to its mass. Had we chosen the second as our unit of time, we would have obtained (44) E_0 = m c^2. Mass and energy are therefore essentially alike; they are only different expressions for the same thing.
