<div>Think of the electron as a photon in a box of its own making. Ditto for the positron. When you open one box with another, each is a radiating body that loses mass. All of it. And then it isn't there any more. </div>
<div> </div>
<div>Unfortunately some people say mass is all down to cosmic treacle, which flatly contradicts E=mc˛. Think of it like this: photon momentum is a measure of resistance-to-change-in-motion for a wave propagating linearly at c, whilst electron mass is a measure
of resistance-to-change-in-motion for a wave going round and round at c. Just like in Martin's box. And to make that wave move, you just add a bit more photon so that after it's gone round, it doesn't quite get back to where it was. Draw a circle repeatedly
on a piece of paper, then repeat, but this time with your wife pulling the paper sideways. </div>

Subject: Re: [General] relativistic mass</div>
<div> </div>
<div>Dear Andrew,</div>
<div>The paper "light is heavy" is no more, and no less, than a supposedly didactic and the only consistent explanation of special relativity and its consequences. Most important points are that there are some confusions:</div>
<div>1) mass is not matter</div>
<div>2) energy is equivalent, exactly the same as, mass: E=mc^2</div>
<div>3) light is massive, both in the inertial and gravitational sense, as is obvious from experiment</div>
<div>4) the greatest confusion is about light being massless, which indeed it would be if it couldn't/didn't move. The whole point is that light is always moving at the speed of light, so it is a non-existing limit.</div>
<div> </div>
<div>Weighing a box with a molecular gas, or that of a "photon" gas give the same kind of result: the gravitational mass of the gas plus the weight of the box. Light is gravitationally deflected by large masses, experimentally. Light carries momentum and energy.</div>
<div> </div>
<div>There is nothing new in what i say, it is consistent with Einsteinian relativity an represents the vision of Herman weyl too, and many others</div>
<div> </div>
<div>Best, Martin</div>

<div>> Dear Martin,</div>
<div>></div>
<div>> In your "Light is Heavy" you state:</div>
<div>></div>
<div>> "In the case of light, the rest mass is zero, but the gravitational mass equals the inertial mass, which is identical to the relativistic mass."</div>
<div>></div>
<div>> Do you have any reference for my contention that the relativistic mass of particles is bound EM-radiation?</div>
<div>></div>
<div>> In the case of electron/positron annihilation, restmass is converted to relativistic mass & then to radiation. However, I do not know of any text or paper that identifies relativistic mass as bound EM-radiation. Your statement is close to that.</div>
