In 1969, Cohn [53] unfortunately attacked the problem anew, unaware of<br />

the previous work in the area. (Somewhat surprisingly, the paper is published<br />

in the same journal that carried Ellis’s final results just three years<br />

earlier.) The reason that Cohn’s paper is unfortunate—rather than simply<br />

another instance of blissful ignorance—is that, unlike the previous participants<br />

in the saga, he got the analysis wrong. This was quickly pointed out<br />

by Kolsrud [125] in that same journal.<br />

Fortunately, Cohn did not retreat from the subject; six years later, he and<br />

his Ph.D. student Wiebe attacked this problem again [54], making due note<br />

of Cohn’s earlier mistakes; and, this time, the correct results were obtained.<br />

Cohn and Wiebe based their results on the four-potential expression obtained<br />

by Kolsrud and Leer [124]; their manifestly-covariant field expressions are, in<br />

the opinion of the author, the easiest to come to grips with, from the viewpoint<br />

of modern notation and concepts, out of the various treatments listed<br />

above (although, mathematically speaking, they are all ultimately equivalent).<br />

As far as the author can ascertain, the field then again lay essentially dormant<br />

for another seventeen years, until the author, as blissfully unaware of<br />

his predecessors as they were of their predecessors, attacked the same problem<br />

again, from first principles. The motivation for this was that, following<br />

the successful derivation of the dipole equations of motion of Chapter 4, the<br />

author wished to use the retarded fields, together with the dipole equations<br />

of motion, to obtain the radiation reaction equations of motion for particles<br />

with dipole moments. Not being, at the time, able to find the retarded fields<br />

listed anywhere in the literature (the works cited in this section essentially<br />

being a set of measure zero, compared to the total volume of physics literature<br />

of the past century), the author proceeded to derive the desired results<br />

from scratch.<br />

The results found by the author are presented in the following sections<br />
