Heaviside started with moving charged matter and then applied some heavy mathematics to Maxwell&amp;#x27;s electrodynamics, while Einstein used nothing but the fundamental ideas of space and time, some simple algebra, and the two relativity principles (all physical laws look the same in all inertial frames, and observers in different inertial frames will measure the same value for the speed of light). Einstein&amp;#x27;s analysis is free of any special assumptions concerning electricity in particular and the nature of matter in general: to put it bluntly, Einstein saw the whole forest, while Heaviside and Thomson were looking through a magnifying glass at the bark on a single tree.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;royalsocietypublishing.org&amp;#x2F;doi&amp;#x2F;10.1098&amp;#x2F;rsta.2017.0448&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;royalsocietypublishing.org&amp;#x2F;doi&amp;#x2F;10.1098&amp;#x2F;rsta.2017.044...&lt;/a&gt;</text></comment>
