Wouldn`t anyone like to be aware of all the discoveries made before his
death?
Einstein said something like: "Keep it simple, but not too simple!"
Scientists have in many instances followed Einstein`s advice and reduced
things to simplest terms. Maxwell`s equations as simplified and
explained by Heaviside have been used to successfully predict EM
behavior for a century.
Just to be picky, Heaviside predates Einstein:

They give the answers needed so there has been
no great search for a replacement.
The research at CERN on colliding beams is more likely of interest to
those working with ionizing radiation than to those working with the
nonionizing type we use in radio telecommunications.
There is and was agreement among many with Kraus when he wrote on page
37 of the 3rd edition of "Antennas":
"Although a charge moving with uniform velocity along a straight
conductor does not radiate, a charge moving back and forth in simple
harmonic motion along the conductor is subject to acceleration (and
deceleration) and radiates."
An interesting view of the mechanism of radiation is given by B.
Whitfield Griffith, Jr. on page 315 of "Radio-Electronic Transmission
Fundamentals".
