Hi Kevin,
What was asserted in The Maxwellians was that Maxwell died in the
middle of a rewrite. It did sound like there was a controversy on his
particle (or little eddies?) form of the equations for a field approach.
Perhaps that new version would have dropped the use of quaternions?
I will try this...thanks,
Jeff

Seems like many of the email on this reflector has nothing to do with

seems to me to be of general
I am sure what you say has value Tom. It just seems this one has been going on
a while. It did prompt me to go out and look up Maxwells equations just to see
what you were all talking about and it is interesting but the math is certainly
over my head. I hope my comments did not offend anyone.
I for one have been enjoying the thread.

Was just puzzled.
The math is hard having forgotten most of that myself especially as I
only barely understood it back in college 40 years ago. The book I am
reading, The Maxwellians, is more a science history book than a book
on the equations themselves. Interesting
For those who might have an interest, there is a brief paper that summarizes
Maxwell's equations and shows the connection between the different notations
used: differential form, original form, quaternion form, and so on.

Sorry, but your opinion is just that.

points of the 43 foot vertical.

I have used it with a 44 foot doublet fed with twisted pair made from #26 AWG
Teflon coated, silver plated wire and it tunes nicely from 40m through 10m.
The 88 ft version should tune just fine on 80m with some tweaking. As with

Hello all,
