E=MC²
From Tardis Wiki, the free Doctor Who reference
In 1905, Albert Einstein came up with the mathematical scientific conclusion of E=MC². (TV: The Lie of the Land)
Alternate reality
In an alternate reality created by the Monks, they made it look as if they helped Einstein come up with this conclusion. (TV: The Lie of the Land)
Behind the scenes
The famous conclusion, E=MC², only holds for a body at rest. The more general conclusion derived by Einstein was, in fact, E2=(MC2)2+(PC)2, where E represents the energy of the body, M represents its mass, C is the speed of light, and P is the body's momentum.
