Maxwell published and his equations have been successfully used ever
since.

My ARRL Antenna Book says in its chapter on "Computer Programs":
"The availability of computers in the 1960s provided antenna designers
with an alternative. They could develop software to simulate the
performance of antennas. In general, these techniques either numerically
solve Maxwell`s equations by discretizing the problem using intergral
techniques such as Moment Methods (MOM) as discussed in Sec. 14-11, or
differential techniques such as finite elements or finite
difference-time domain."

Is the "Antenna Book" bull too?
