= Deriving magnetism from electricity and relativity

It appears that <Maxwell's equations> can be derived directly from Coulomb's law + <special relativity>:

This idea is suggested by the <charged particle moving at the same speed of electrons thought experiment>, which indicates that <magnetism> is just a consenquence of <special relativity>.
