Does the inertia of a body depend upon its energy-content

Abstract:

Let a system of plane waves of light, referred to the system of co-ordinates (x, y, z), possess the energy l; let the direction of the ray (the wave-normal) make an angle φ with the axis of x of the system. If we introduce a new system of co-ordinates (ξ, η, ζ) moving in uniform parallel translation with respect to the system (x, y, z), and having its origin of co-ordinates in motion along the axis of x with the velocity v, then this quantity of light—measured in the system (ξ, η, ζ)—possesses the energy l∗= l 1− v c cosφ√ 1− v2/c2 where c denotes the velocity of light. We shall make use of this result in what follows. Let there be a stationary body in the system (x, y, z), and let its energy—referred to the system (x, y, z) be E0. Let the energy of the body relative to the system (ξ, η, ζ) moving as above with the velocity v, be H0. Let this body send out, in a direction making an angle φ with the axis of x, plane waves of light, of energy 1
