Re: del F = 4pi J ... correspondence between Clifford Algebra and vectorformulation of electromagnetism

["John S. Denker" <jsd@MONMOUTH.COM>]

For the benefit of those afflicted with browsers that
can't display the symbol font, I put up a DJVU version
of the Clifford Algebra / Maxwell equations exercise,
namely:

The content remains the same, namely:

Using cross products is like eating soup with a fork.
Clifford Algebra is the spoon -- it's easier and gives
a better result.
