洛伦兹变换与电动力学的比较

Einstein made it very clear that special relativity came from Maxwell electrodynamics; Feynman spoke extreme highly of Maxwell electrodynamics. Since both theories involve electromagnetic fields of uniformly moving charges, it is reasonable and necessary to compare Lorentz transformation with electrodynamics.&nbsp; The results of comparison are as follows: the correct electromagnetic field of uniform moving charge is obtained by electrodynamics without any hypothesis, all the reasoning processes are in line with the accepted logic law and the accepted empirical facts, and the conclusion is rigorous and reliable; Lorentz transformation can also be used to find the electromagnetic field of uniform moving charge, but it uses two assumptions - &quot;the principle of constancy of light speed&quot; and &quot;the principle of relativity&quot;, these two assumptions have logical errors, the resulting ruler and clock are virtual mathematical expressions, not real physical space-time.<br />&nbsp;
