Re: Maxwell's Equations.

In reply to this post by kevinr@coho.net

The two volumes of Maxwell's "A Treatise on Electricity and Magnetism" were
reprinted by Dover, bound as one (very thick) volume. It does make for
interesting reading! Now it gathers dust on my shelves next to another
fabulous classic "The Theory of Sound", by Lord Raleigh (also two volumes
bound as one by Dover), a great source for solutions of eigenvalue problems.
Another huge volume by Dover is "The Scientific Papers of James Clerk
Maxwell". These books are probably still available in one form or another.

Interesting discussion. Gives me an idea.

We'll soon be announcing a very cool new test instrument (it's the same size
as our T1 antenna tuner but not related to it in any way). We'll give one of
these to whoever can suggest, by next Thursday, the most plausible

I only know of three Maxwells. One had a silver hammer, one was a spy who talked into his shoe, and the third made coffee with a guy named House (possibly related to the doctor on TV).

I've got a loonie (Canadian dollar coin) that says it's an L/C meter in a package that size. The world doesn't need another DVM and it's too small to be a scope!

No need to limit ourselves to only 11 dimensions, Occam's razor be
damned. I would simply resort to Shannon's trick and employ the fact
that in a hypershpere of VERY high dimensionality nearly all of the
volume lies very close to the surface... Only, I'm quite busy at the
moment trying to figure out how to hook up this big screen tv so will
leave the details as an exercise for the reader.

Lu Romero - W4LT

Re: Maxwell's Equations.

In reply to this post by kevinr@coho.net

Wayne's post reminds me of a story from my past.

Early in my broadcasting career, I wanted to rid our station
of the little jaggies that plauged the edges of Chroma Keys,
the process that is used to put the weather man in front of
the map using a blue or green screen as the background that
"disapears" in the process. The jaggies were prevalent in
the "good old analog days" of TV and looked just awful to my
young, inexperienced eyes.

As I searched for an answer over countless weeks, the wise
old station senior engineer watched with amusement at my
experiments in futility with lighting, colored gels on the
backlight, camera enhancer adjustments, background paint
color tweaks and production switcher keyer tweaks but
offered no clue to my inquisitiveness, just smiles and head
nods.

Finally, I summoned the courage to personally approach him
and ask if knew the reason why this was the way it was. He
nodded yes; his charge for the answer was lunch at the local
eatery down the street, a local bar-b-cue place which, had a
name, but everyone at our station called it "The Pig Bar"
due to the sign hanging on a pole above the door... A red
outline of a pig with the word "BAR" in white block letters
within.

After downing several pulled pork sandwiches, some Halupki
and an Iron City Beer, the wise old engineer grinned and
said "I admire your perseverance, kid, but everybody knows
that that condition is caused by the algebraic sum of the
diverging vector".

>From that moment on, anything that mere mortals like me
could not understand was always refered to as being caused
by the algebraic sum of the diverging vector.

Re: Why I won't purchase K3

In reply to this post by Johnny Siu

Johnny,

Because you like to build, please do not think that SMDs would be too
difficult for you to handle. I, and no doubt other people, felt the same
concern before starting to use SMDs in homebrew projects. Mounting multipin
SMD ICs is not difficult after some practice.

Tweezers of the locking type should not be used to hold SMDs because they
can make very good SMD Launchers.

If of any interest to you I think that I still have some notes and/or
articles about SMD construction methods, which I could send to you if I
still have them.

The main problem that I have is our Temple Cat who would like to help with
any build. Bribes does not work with her, and she takes an unhealthy
interest in any multipin SMD - ignores resistors.

Was some his disciples, aka "The Maxwellians," that finished the theory

Re: Maxwell's Equations.

There was a group which disliked his use of quaternions so he was forced
to rewrite the system into other systems. Most of the work was carried
out by others but for him to publish he needed peer review so he caved
into the larger group. I am reading his original work from 1873 and
finding it very enlightening. Even though I have studied the
Heaviside-Gibb's version of the Maxwell equations many times the
quaternions he used in the original paper were very hard to find. Luckily
they are proliferating online these days.
