The atomic bomb

Albert Einstein was not part of the initial inventing of the "Atomic Bomb" but without his e=mc2 equation and his amazing intellect it never would have been accurately made. Relativistic mass and energy are 2 different names for one and the same physical quantity. When ever a system has an energy E it automatically has the relativistic mass m=e/c2; whenever a system has the mass M, you need to assign it an energy e=mc2. Once the mass is known so is the energy and vis versa. Energy can be transformed from one variety to another, but it can neither vanish nor be created from nothing. Kinetic energy is motion energy and is used in the bomb to separate the atoms in side. Einstein figured all this out!
