How did you learn about this as the accepted way?

I'm a part-time teacher and it is described in a physics
history book that is, unfortunately, at work. Interesting
book as it gives a biographical treatment of the major
famous physicists from Galileo to Einstein. The Maxwell
and Heavyside sections are particularly interesting to
me.
