SNIP CLASSICAL THEORY OF ORGAN PIPES AND MICROWAVE
WAVEGUIDES... IRRELEVANT TO THIS DISCUSSION
No. You are the one claiming these biological constructions are akin
An organ pipe is a wave guide and illustrates how they work and what a
standing wave is, and what makes a good waveguide. All musical
instruments make use of standing waves in some way, wind instruments
use standing waves in air, and strings use reflected vibrations in
tensioned wires, or similar materials, chimes, bells, etc., ditto.
I had to study waveguides for radar back when I first joined the Navy in
1972. I actually liked them, unlike most of my class I did very well with
them but to me they made perfect sense. For some reason I found it rather
easy to map them out, figure out how to adjust them to actually work. Went
through the school on Treasure Island, got to my ship and never worked on
them again. (Of course since we never got shot at we didn’t have to fix
holes or replace sections.) It was one area that I really shined at, I was
pretty good at most of radar electronics, but that one I did very well.
Not that different than my start in electronics. USN ET-A schools
(1965) through phase A3 at G.Lakes then HFDF-M in Pensacola. I worked
as a CTM with a TS-Crypto clearance and was E-6 in 4 years, and got
out in 6 years.
My OM had a Radio and TV repair business and I could play to my
heart's content building things. (he never charged me for the parts
unless I wanted/needed something he didn't already stock) I started
learning when I was 7, and had a head-start in electronics before I
got to school.
I wired/rewired houses, business, some small electronics, motors, pumps etc.,
for my dad (I was his first employee, hell, I was his only employee from age
12 to 20.) Also did sheet metal, design and fabrication of air ducts in new
construction and in enplaced homes and businesses, installed furnaces and
air-conditioning for same.
I was “fair” with electronics, got better with the Navy, but never really
worked it them much after, though I did build a few PC computers for Diane
plus did most of the Macintosh work on my own computers, we were a mixed
couple, I was Mac, she was PC, we got along pretty well in spite of that. ;-)
I played percussion in the concert and marching bands while in A
school. One of my buddies played cornet then and we both got to
Pensacola for C school. (and tied for first in class)
Personally, I sucked at music, I like music, but (according to a guy that I
once worked with for several years, and one time filled in for as a drummer
when the machine he run at a book bindery broke his arm, I have no rhythm -
at all. I was forced to agree with him, next week he had another friend with
no musical ability at all fill in, he was much better.)
The music they played was pretty simple, after all most of the musicians in
it averaged 50 years old. The “fans” were more diverse, from 8 to 108. I
swear on that last.
My C school was for a system that couldn't fit on a warship, so I had
only shore stations. I did get onto the USS Sequoia, to repair the TV
in the crew's quarters. It was the presidential yacht back when
presidents had yachts and I was in D.C. awaiting a background
investigation for a security clearance.
The FBI did their investigation on me before I went in, I was SUPPOSED to be
a Nuckee in electronics. When I state that the FBI had a big folder on me I
mean it, “Please state every address you have lived at for 24 hours or more
Ha! My dad was also in the Navy at the time of my birth and for about 8 years
more, we bounced all over the east coast and the mid-west for most of those
years: Philly, to Boston, to NYC, to upstate NY, to Marceline, MO, to Newport
News, to Jacksonville Beach, FL, back to MO. Back in the 50’s traveling by
car you had a lot of trips where you would end up staying in a motel for a
day or more, I remember our driving to Jacksonville Beach and having to stay
at one motel for, I think, 3 days because of extremely heavy rains. 1948?
Studabachers were not exactly great for driving in such storms, nor did they
have much in the way of windshield wipers, hell, I can’t really think of
any 1940’s car that did either. And “2” lane “highways” that many
times were more gravel than concrete or even asphalt. Tennessee was “fun”
to drive through, though I did enjoy the motel. I was 5 at the time, so of
course I had fun.
It took me, my parents, both sets of grandparents, my Uncle Verell and his
wife, a couple of my dad’s Navy buddies (and boy weren’t they fun to try
and track down after up to 21 years) to finally get most of the required
addresses. I doubt we got them all.
Then in “B” School, I think, I dropped out of going to Nuckee School and
went straight radar electronics. Be careful when dropping something you
signed up for when it comes to the military, it will come back to haunt you.
The teacher I most pissed off by dropping Nuckee school was a hardass and was
friends with one of the First Classes in my dept. on my first ship. I got
busted from Third Class to Seaman for being THREE minutes UA, on a ship in
the middle of the Pacific Ocean. Most of the at sea shop watches, in that
dept anyway, you were considered on time if you were plus or minus 5 minutes.
We had one First Class who went around several time every day resetting all
the clocks to the “correct” time. I am sorry, but he was never correct.
It was nothing, but I was, probably, a couple of minutes late for that watch,
didn’t argue about it at Captians’ Mast, got busted to Seaman. Eh, at
least my dad didn’t hold that against me, it seems he had a couple of those
himself over the 14 years he was in.
As you can tell, I enjoyed my time in, really.

It might have been that I had played Cornet in band class and partly because
I helped take, and put back together, a pipe organ for one of the churches in
my hometown. The guy doing it taught me a lot about standing waves and how to
think in them,
My uncle repaired/tuned pipe organs and sold pianos - but my interest
didn't take off until I retired and built a few Tesla coils and
started studying resonance etc..
I tried a Tesla coil, once, it died a horrid, and very smoky, death. RIP

I always visualized them as sound tubes, or organ pipes, count your waves,
terminate. Hmmm, actually sounds a lot like SCSI on my early Macs, those
could be tons of fun if things didn’t go correctly.
I really need to dig out my old class books on waveguides, I think I still
have them somewhere, might be at my sisters from when she cleaned out my
dads’ house after he died.
I seem to remember that they used an analogy where they take an open
transmission line and by spacing a series of elements closer together,
wind up with a solid waveguide. I slept through most of that though
Not positive after all this time, but, as I recall, that was how they did it
in class, transmission line that on to waveguides, on a box-section waveguide
one dimention was power, and lord help you if you miscalculated it, smoke and
fire could ensue. The other was mandated by the frequency. Now how to
calculate those at this late date, don’t ask and I won’t scare the cat.
The cat knows all, according to cat. Down, Spot. (Yes, my cat’s name is
Spot, he is black and white and is, supposedly a Tuxedo, but has plenty of
spots, under his chin, on his elbows, on his face and one that is rather hard
to miss on his balls. Diane named him Loki, but everyone calls his Spot.)

I hate to say it, but I think you have pretty well dumped on poor
Oh, right, I DON’T hate to say it, Hammond is a complete moron and an
annoyance, has been one for most of a decade at least.
I don't bear him any ill will, but it is scary to think that anyone
reading his tripe may actually think there's a scientific
justification for believing in life after death.
Religious people have already learned to swallow a lot of paranormal
crap. I'm afraid cellular level intelligence and microtubule
waveguides aren't that big a stretch to the religiously afflicted
I point out to the website of “Time Cube.” If you have never been there,
do so, but have plenty of aspirin handy, I guarantee it that you will need
them. I suggest a whole, BIG, bottle if you actually try to read much. Just
thinking about it brings back a headache and I have not been there in 7 or 8
years. (I did just take a quick look, it is still there and as horrifying as
ever. Spot, get my aspirin, now.
Just one of a myriad of kooks, yesterday I was on Rational Wiki, category
“kooks.” Lots of them, many with plenty of followers, and all nearly, or
more so, as nuts of TimeCube Guy.
