this can, by writing the computer algebra programs of Appendix G to complete<br />

the radiation reaction computations for him before the termination of<br />

his Ph.D. scholarship (indeed, looking now at the expressions in Appendix G,<br />

before the end of the millenium). He has, however, discovered that this lid<br />

is in fact the base of an even larger can of worms, arising from the final<br />

equations of motion (6.128), (6.129) and (6.130) above. He is informed by<br />

those of wiser years that this is actually a general phenomenon of Nature: as<br />

far as anyone can tell, it’s all worms from here on up.<br />

It would therefore probably be either overly ambitious, or else foolish<br />

(or quite possibly both), for the author to attempt a comprehensive discussion<br />

of all of the issues that arise from a consideration of equations (6.128),<br />

(6.129) and (6.130). Instead, we shall only give here a brief indication of the<br />

successes of these equations, their failures, their questionable aspects, their<br />

complications, and their intriguing properties. We shall also, in the following<br />

section, analyse a simple yet instructive application using just a small subset<br />

of these equations, which will bring their successes and limitations into<br />

starkest relief.<br />

Let us begin with the unquestionable successes of the equations (6.128),<br />

(6.129) and (6.130) (which we shall, for sanity, refer to as simply the “final<br />

equations” for the remainder of this section). Firstly, it will be noted that,<br />

as promised, the electric charge mass term<br />

− 1 2 q2 η 1 ˙v<br />

has the correct coëfficient: in Section 5.5.8 of Chapter 5, we found that<br />

− 1 2 q2 η 1 ≡ m q e.m..<br />

This is in contrast to the incorrect factor of 4/3 in Lorentz’s [137] result,<br />

equation (6.1). Now, it is instructive to note just which aspect of the theoretical<br />

framework used in this thesis repaired Lorentz’s erroneous result.<br />
