>Youre good. Your comments on the book cover and on the War that we
are NOT waging are good. You should write a book sometime. A quarter...25¢.
each book.
Ah, thats chicken feed, in technicolor.
>In your case, you would want flashy and exciting. I would think something like
with the top blood red and blood running down the book from that area and the title in
that red area in stark black.
I would want to use some Mexicanny colors, as well.
>There are no fonts associated to Mexico that I can think of but there are
a jillion fonts and since the folks you are writing about came from there some primative
font might do good.
And there is the juxtaposition of technologies that might be of interest...like a scene of
a priest holding an obsidian knife in one hand and a flowing heart in the other with it
held high offering it to the Gods and the site is obviously preColumbian but there is a
jet vapor trail in the sky.
That's good. But remember, the picture must also include a Viking
warship fleeing for land before a Carribean hurricane.
>No, now you are being silly.
And an image of two-headed, feral, rabid dogs with extra
fifth legs growing out the sides of their necks, lurking in packs with fangs barred in
front of crumbling, ice-encrusted skyscrapers and the Statue of Liberty half blown-away
with the upheld torch sagging sideways (courtesy of the jihad).
>On to a thankful other subject, I will send you these Image du Jours if you don't
mind and you can check my zeros.
Send them. I owe you favors for a few Samuel Smith ales.
>Did you know that there are drawings and property is being purchased so that the
world's largest mosque will greet all approaching Heathrow, to proclaim that Britain is
the first modern country to be taken over peacefully by Islam in a jillion years. They
have protests in some cities now and the Islamist carry signs proclaiming that they are
the new Britons and soon Britain will be a fundamentalist (but still modern) nation.
(After they remove every portrait from every museum and burn them and destroy every statue
with a human figure.)
I truly believe this will happen. I don't know when but I will see the beginnings of the
desolation in my life time.
Now that really IS scary. I didnt know about the
Heathrow mosque. England had better get her royal act together. Its enough to make
me wish that Maggie Thatcher were still prime minister. You remember, of course, how the
John Birch society et al used to say that communists would take over the western free
world without ever firing a shot. It never happened. But this time, you know ... Im
not so sure that it cannot happen. Allah is, apparently, more powerful than either Mao or
Marx.
I read a commentary a few moons ago that said, in reference to
the Muslims rioting and burning everything they could find in Paris back a couple or so
years ago the commentary said that when the Watts riots occurred in the 60s, the
protesters were holding signs that said "Give Me a Job." The Muslim rioters and
arsonists in Paris were holding signs saying "God is Great!"
We are at war.
>No. THEY are at war. We are at peace until we become Islamist. That or death. They
will kill and die for their religion. We only ridicule ours. We do not think it is worthy
to kill or die for anything.
Right, I would have to agree with this. But that sure
doesnt mean we cannot find an excuse to wage war. Bushs little war in Iraq is
not being waged because he or anyone else in D.C. believes in anything. It is a bellicose,
face-saving farce. Wiping out the Taliban that was good. I approve of it. But
invading Iraq was a rash, premature move. 4,000 and counting. Its a friggin
civil war for godssake. Let them kill each other. Who cares?
Personally, I think we should have invaded Saudi Arabia and
grabbed all their oil. (OK, OK ... that's just wishful thinking.)
>Archie Bunker proposed an even better solution a long time ago. He said that when
everyone enters the air liner, they are handed a loaded, automatic pistol. They give it
back when they get off the plane.
That would be interesting to see. But, the Muslims should not be
given guns. Only Christians and Jews and Buddhists. Hindus? Im not sure about them.
They feed rats in the temples and worship starving cows. And the Sikhs are pretty scary.
And the Taoists -- I'm not sure they have enough nerve to operate a semi-automatic
handgun. They'd probably let it drop to the floor during one of their ahimsa vegan chants,
and some Muslim would grab it up and start shooting, redounding to the glory of Allah.
>Right now the book has evolved and "Learning To See" might not be the
best title. Bettie and I are brainstorming right now.
May I suggest "The Unbearable Horror of Descrying" or
perhaps "Pluck Out Thine Own Eye Before it Learneth to See"? Im just
trying to be helpful.

This is why I would rather dig ditches than program or
work with a fucking computer. I have tried for LITERALLY a half hour to send this e-mail
to you, using three different mail servers. The previous one apparently did not include
the attachment. Damn those people. If I had written software that bad, I would have been
fired.
Last attempt:
>We do not read for entertainment on a "device." The people most familiar
with such devices...laptops, desktops, whatever, do not read anything. Most are almost
illiterate. We look for information on the computer and not read for pleasure.
You're funny. And what you say is (usually) true and correct. You're
funny and right. Good combo. You would make a good producer for somebody. (Or good
husband?)
>I have the complete works of Shakespeare in several versions in both digital and
analog formats and I would not use the computer, even though I would have immediate call
back to see whom was whom, what the period was, what certain words and phrases meant. And
these things are done by highlighting the word on the screen and clicking to go back to
the character list and the like.
I have reading on "screens". I love books with palpable
pages, into which I can insert bookmarks.
>Charlie, I am beside myself in trying to do this cover business. I have too many
conversion factors working here. I will muddle through but I will have to do some more
research to do it.
Well, now you're scaring me. If you, of all people, are having
difficulty with muddling through and not having a system -- YOU, of all people -- what the
heck chance do I have at executing that same task?
Oh, I know. I'll just hire you as my consultant. And you can say,
"As your consultant, I hereby advise you ..." You love to say things like that,
don't you? :o)
I am at the present time very "psyched", as the hippies used
to say. I have made a major discovery. You'll recall I made that little joke-ish comment
recently about "I knew that someday my master's degree would be worth
something", or something like that. Well, I think I have found the keyhole into which
to insert the enzyme of my M.S. degree, thereby effecting a transformational shifting of
the tertiary and quaternary muddle of my lost-at-sea life (good god, talk about mixing
metaphors ...)
Have you any idea (I did not!) how huge the "online"
teaching profession has become? I read (though I'm not at all sure that I believe it) that
70% of all students are enrolled in online courses. True or not, that is at least
indicative of something that is true: Online teaching is booming, and they are hiring, and
will be hiring, more and more instructors. You need a master's degree to do it. They are
also looking for people with real-world, professional experience in the fields they are to
teach. They are also looking for people who have previous classroom teaching experience.
Well guess what, Ken. I have a master's degree. I have over 20
years of experience in software development and mathematical modeling in quantitative
finance, physical and biologic science, and supercomputing. And I have taught and/or
tutored at four colleges. Imagine that.
I just ordered $70-dollars-worth of books from Amazon (three books)
about how to get a job and keep a job and manage your time and acquire the software tools
and so on to be an online instructor. I was going to send out about 70 resumes, but now
I'm waiting for the books to arrive before I do it. I may get some good tips.
I want to respond to parts of the e-mail you've sent in the last
couple of days, but right now, I reading one of my books. Amazon is so damn crafty -- they
are REALLY good at business. One of the best. They offered me, for $2.49, to have access
to the full text of one of the three books I just charged to my debit card. So I did it. I
now have to go back to reading my online book.
Soon ...
Charlie
P.S. Here is a poem I wrote, in the style of Walt Whitman and Allen Ginsburg,
to and about my life with my former wife. Every word of it is true, based on real-life
experiences. I wrote it in a hospital bed, in a state of semi-despair, with IVs and trache
tubes and stomach tubes hanging out of me. And yes, missing my wife and my life. For your
entertainment and/or amusement. It's entitled "And That Only", and it's
unfinished. It'll probably remain so.
OK ... now it's a WP attachment.

>Here is an old grandfather with very basic computer
graphics problem who asked a 5th year art/computer major what program she uses and if it
can control gamma, move clips with the edges as blurred as the subject material, if it can
change contrast in one section without removing the section and then manipulating it, and
then moving it back to the original. That sort of stuff.
>She has no idea.
I have PhotoShop Elements, which is cheaper than the full-fledged
PhotoShop. But it does everything I have ever wanted to do. It does all that you mention
above, and about 10 million more things, too.
>I guess by now you'd just of soon'a' not had me find you, huh? But e-mails don't
have to be read all at one time...or even at all...and they don't all need to be answered.
I am just thinking out-loud at you.
Truth is, you write some of the most interesting e-mails I've ever
received, and I enjoy them. I think you must type faster than I. And I'm pretty sure
(understatement) that you manage your waking hours better than I.
Speaking of time being spent on thinking out loud at each other with
our fingers ... I just this morning received e-mail from a beautiful, bright, cool woman
who I have not heard from in over thirty years. We worked together at the
deaf-blind-retarded children's camp in Mississippi. She is now an M.D., as is her husband
of 28 years, living in Eugine, Oregon. She went back to school and did graduate work in
philosophy, anthropology, bla bla bla bla bla. The point is, she asks me (because she had
a dream about me and awoke with a strong desire to find out what I've been doing for 30
years) -- she asks me, as I just said, "Charlie, what have you been doing for the
last 30 years?"
Now, this is a smart and interesting woman. How much time would it take
me to tell her what I have done for 30 years? I need to apply for on-line teaching jobs
and finish my novel. Maybe you could e-mail her and tell her what I've been doing. Let me
know if you have the time. [insert smiley face here]

Still MORE???

>These particles are not atomic particles, as have been mentioned earlier,
but are physical to the point of being .000002" to .00008" in diameter. However,
as small as they may be, they are moving very fast and may be meeting a spacecraft going
fast itself. One of these micrometeorites can leave a .002" diameter pit in a
spacecraft window. For long missions in high-flux density environments, the window could
soon become unusable.
I wonder how it is, statistically, that some disaster
or near-disaster has not occurred with any of our space flights. There's a lot of God's
debris and human junk whizzing around out there (I started to say "up there",
but that is outdated.)
Oh, just a jolly I just thought of. The Flat Earth
Society still exists. They can be found online. But the guy who started the society a long
time ago was serious. He spent hours trying to measure curvature in large lakes and seas,
and he found no evidence of curvature. He even said -- this is my favorite -- that he had
accumulated the data to show that some of the longest rivers in the world fall in
elevation, over thousands of miles, by only one or five or ten feet. He says, how can the
earth be curved if a river falls in elevation by such a small amount? Obviously, the earth
is flat. The thing that keeps the oceans from falling off the edge is the Great Ice Wall
encircling the flat Earth. We have not seen it because all the governmental agencies and
scientists have hidden it from us and will not allow us to go there.
The present-day Flat Earthers have turned it into a
spoof, thank heavens (no pun intended).

Subject: Re: Something Else
I pretty much agree with all you wrote, and it is
insightful. I'm glad you are teaching courses. Students should be exposed to instructors
who think like you do and who are not afraid to verbalize it. History is a living process,
and it is quite fascinatingly complex. Most "history" misses the kind of
insights you come up with. I should send you sometime my treatise (if you've never heard
it) on the causes of the nature of the relationship between man and woman.
No one says this stuff, but it's so clearly true.
Maybe I'll cut-and-paste you my treatise. (You also need to see my treatise on the
"progressive consumer tax". I know that is supposed to be a textbook example of
an oxymoron, but that's only because the people writing the textbook are not as smart as I
am. This is a tax plan that Republicans, Democrats, Socialists, and Libertarians would all
approve of enthusiastically. It's brilliant.)
I have seriously considered going back and getting an M.A. or
M.S. in some kind of interdisciplinary area including history, philosophy, anthropology,
etc. I just have to figure out how to fund it.
A passing note of interest to me: You still occasionally
use the word "liberal" disparagingly. I agree with what you say in most the
contexts of your usage the term; it's just that I prefer to disparage the term
"politically correct", which attitude and position I almost always unmitigatedly
excoriate. It's just that, how can it be that positions such as "the occurence of
accelerating anthropogenic global warming is extremely likely to be a correct
proposition" or that "many people tend to treat animals very badly" (as
Bettie knows) -- how can it be that such things are labeled "liberal" beliefs?
This is no more correct that it would be to say that my wanting to defend everything from
the Magna Carta to Galileo to the U.S. constitution and bill of rights from these
fanatical Muslims makes me a conservative. I ain't no conservative, and I ain't no
liberal. And I would be completely unelectable, as would you, if we were silly enough to
run. (Hey, it's a compliment.) I don't toe nobody's party line.
I find it very interesting that we -- you and I -- seem to
be so much on the same wavelength about the majority of things. Isn't that strange? I
think that the external observer would put us in different political/social camps, and yet
we think a lot the same. Hmmm ... well, the reason does not matter, because I have to get
back to the novel and the online jobs.
You know, of course, I have not the time to respond to every
sentence or paragraph of the things you e-mail to me. However, the pictures and the
accompanying descriptions are darn interesting. I am impressed with what you did. You are
a jack of all trades with an engineer's mind.

Subject: Sometimes you don't gotta even know how to spell Kalkulus.
Sorry I haven't responded to your e-mails of the last two days.
I'm being pressured by these online schools to respond to their requests for phone
appointments (this is for going to school, not working as an instructor at the school -- I
haven't really got to that part yet, though I am still furiously doing research).
In one of your e-mails you mentioned that DeVry (you
attended DeVry!!??! -- they're on my list, as student and as instructor) taught you just
exactly what you needed to know to get something done, and you didn't stand around the
water jug philosophizing about calculus.
Well, you're perhaps a bit like my character Odd, who is
Dylla's brother, A.D. 1000-something in Norway/Ireland. He is a genius among geniuses, and
his sister Dylla has powers of a witch and is a seeress, and probably part goddess. But
that's irrelevant to my point. (The mere awareness of the irrelevance of my divers
digressions has never effected a significant reigning-in of my profligate prolixities, of
which your hawk-eyed perception has perchance -- nay, indeed, I might even venture to say:
doubtless -- has made you well aware.)
The point is, my Norwegian character, Odd,
has observed during his travels on his father's (his father is king of Norway) ships that
as one heads south the pole star shifts downward. (Polaris was not almost at the center as
it is today, but they still called it the pole star.) So Odd said to himself, if the pole
star looked as he imagined it then we were, thinks he, to erect a vertical instrument with
wires precisely placed horizontally at even intervals and then make sightings (on land,
where the wave-tossing ceases) of the elevation of the lodestar as a function of how far
we have travelled (based upon information from approximated average speeds with knotted
ropes, from sunstones, lodestones, etc., which data Odd accumulated assiduously on his sea
journeys.
From comparing his geometrical drawings (not using math,
just geometry of the eye) with his sightings using a vertical device, he realized that the
exact movement of the pole star up the horizontal wires with distance travelled was not
what was predicted by his drawings. However, he realized that if
you made the flat earth curved like a circle, and assume that "straight up" to
you is always perpendicular to the tangent to the earth-circle where you are at (and he
doesn't know the words "tangent" and all that -- he just drew the pictures),
then you get the proper motion of the north star, agreeing with his drawings of the curved
surface. Thus did he deduce that the earth curves. He also observed that eclipses of the
full moon by the earth required that the thing doing the eclipsing was shaped like a
circle, and he observed that things disappear over the horizon with distance, which
implied a downward curvature.
See? Who needs calculus and trigonometry if you have a
sharp eye and a sharp brain?

>We have evolved the conversation into that which I do not do. There are a
million of these things and I hate them.
Ah, Ken, Ken, Ken. Tsk, tsk.
Do the following: Take one of your Mobius strips and -- hey,
really -- I'm not kidding. Go this instant and get one of your Mobius strips which you
don't mind messing up -- or make one real quick that you don't mind messing up. Ideally,
it should have a width of at least 1.5" or 2" or so; that will make your project
a bit easier.
I'm waiting ...
(fingertap, fingertap, fingertap ... )
Are you back yet?
Is the Mobius strip in your left hand? OK, good. Now take a pair of
scissors into your right hand. Use the scissors to poke a little hole somewhere in the
strip, in the dead center of its width. For example, if your strip is 2" wide, poke
your little hole 1" from the edge. Now carefully cut the whole strip right down the
center of its width, all the way around. Rather than getting two separate strips, you get
one new, single loop, but it's twice as big as the original. Hmmm ... that's kinda wierd.
But here's the real surprise. Now repeat what you just did. Cut the new, bigger loop right
down the center if its width, all the way around.
Look what you've got now!!!
Man, now that's a bar bet winner!
There is a three-dimensional version of a Mobius strip. It's a bottle
(Klein bottle) with one side only. It's so very pretty. I think I may order one.
Maybe I should make a bar bet, which you can ponder at your bar. How
long do you think it will take me to get all the comments done on all the pictures?

>Let me ask you this, what is the Mobius strips application? Really.
If I made one out of titanium, or copper, or I made one of cast iron and super-cooled it?
When do we get to the pay off? That question shows the basic difference in you and I, and
that ain't bad...it just IS. Maybe it is the eternal engineer/scientist puzzlement.
Well, did you know that there are factories that use very long
Mobius-strip belts to run through all the turning wheels, because the wear occurs to
"both sides" (but of course there is really only one side ... go figure), and
therefore the belt lasts twice as long, at least theoretically.
Since you love useless things so much, how about this. You wanna see what is
one of my two favorite equations? (The other one is too long to bother with right now.)
It is the value of the square root of -1 raised to the power of
the square root of -1. If i, as usual, denotes the square root of -1, then the equation
is:
i ^ i = 1 / squareroot (e ^ pi)
or you could write it:
e ^ pi = 1 / (i ^ i) ^ 2
This is one of the weirdest things ... it's just beautiful. And scary.
Speaking of applicability, did you know that when the mathematics scholars
came up with topology early in the 20th century, they were thrilled with themselves
because they had invented a branch of mathematics which was completely, utterly
inapplicable, utterly useless to the world of nuts and bolts. They were so proud of
themselves. It was a "fuck you" to the world of applied mathematics and
engineering and physics. They had discovered a perfectly pure branch of mathematics which
was Platonic and True. They (it is joked) used to (and still do) sit around, drawing
publicly funded paychecks, drawing circles and the sides of pretzels, just wiggling with
abstract ecstasy.
And then, guess what happened. Boy, did this piss the topologists off! This
guy, A. Einstein, came along in 1915 and figured out that precisely the mathematical tool
he needed to describe his theory of gravity (the general theory of relativity) was -- you
guessed it. Topology. Einstein taught himself topology, with
the help a former student of his who was a topology genius.
I think that is a great story. But this has happened over and over in
the history of math and science. It seems that every time the theoretical mathematicians
proudly come up with something completely True and Worthless, some pesky physicist comes
along and finds a way to apply it to the real world. Ha ha ha.
By the way, the Klein bottle and the Mobius strip both came out of topology.
As for the usefulness of the Klein bottle: It is a very pretty bottle, as I have said. I
would like one in translucent midnight blue, to set on my bookshelf and collect red
Georgia clay.

Wow. Good writing.
This reminds me of Neitzsche. Here is a quote from Neitzsche,
interspersed with a comment by the guy writing the article:
Neitzsche wrote:
Have you not heard of that madman who lit a lantern in the
bright morning hours, ran to the market place, and cried incessantly: "I seek God! I
seek God!"...
The madman jumped into their midst and pierced them with his
eyes. "Whither is God?" he cried; "I will tell you. We have killed
himyou and I. All of us are his murderers. But how did we do this? How could we
drink up the sea? Who gave us the sponge to wipe away the entire horizon? What were we
doing when we unchained the earth from its sun? Whither is it moving now? Whither are we
moving? Away from all suns?"
Comment: The madman asks questions which imply that: we are
plunging continually, backward, sideward, foreward, in all directions. There is no longer
any up or down. We are straying as through an infinite nothing. We feel the breath of
empty space; it has become colder. The night is continually closing in on uswe need
to light lanterns in the morning. Then he continues: "God is dead. God remains
dead. And we have killed him.
Here the madman fell silent and looked again at his
listeners... "I have come too early," he said then; "my time is not yet.
This is where practicality and scientific thought gives way to
the spirit and emotions.

>l just got this jpg from a correspondent friend in England

They live on the south coast of England. This was yesterday with them playing in the snow
with a snowman.
This Global Warming is going to be OK, I think.
Very amusing. But that's not a snowman in that picture.
It's a snowbird.
Your comment reminds me of why a guy left NASA. Do you
remember that? That bigshot high-up guy, I forget his name. Anyway, he was at a higher
level than my boss's boss, and he was a heavyweight. (The excessive weight was NOT due to
the contents of his skull; he just had big bones.) This heavyweight guy was making a
practice of -- and he made it known in interoffice memos or whatever -- a practice of
throwing out the really askew data points. For instance, if he had readings of 54, 57, 49,
51, 53, 47, 81, 48, 52, 55, 31, 51, etc., he might throw out the 81 and the 31 even though
there was no indication that those measurements were made any differently from the others.
So this good guy, who was a very bright no-BS physics person and who knew a thing or two
about statistics, circulated to the whole department a memo which was just a copy of an
article that had been published by some Ph.D. recently in a journal of math, science,
something. It clearly pointed out the statistical danger of throwing out "bad"
data points based on the assumption that there must be something wrong with this data
point.
Bad move. The big guy got extremely upset at being made to look stupid
in front of the whole place. It was so bad that the good guy was afraid that he was never
going to be able to rise any higher in job or money. So he left for a satellite-making
company in California.
So I suppose that that snowbird picture from the South of England
is a datum which we should not offhandedly throw out. But don't worry, there are a lot of
field workers collecting many, many more data points. We'll eventually end up with a very
nice bell curve.
Do you read all these things like Scientific American and
Science? Man, it's scary. The ice loss in the Arctic, the Antarctic, and Greenland is not
just progressing steadily, it is accelerating. It appears that what we have going on here
is a positive feedback loop. That's scary. But what will be will be. I won't be hanging
around here on our noosphere Mother Goddess long enough to see the sad denouement.
I just thought of a great historical example of why one might not
want to throw out the "bad" data points. Ernest Rutherford is the man who
discovered that the positive charge in an atom is concentrated at a very tiny central
region of the atom -- i.e., the nucleus. (The other competing hypothesis had been the
"raisin-muffin hypothesis", or something like that, which posited that the
negative electrons were distributed throughout a spread-out positive medium, like raisins
in a raisin muffin.) This is how Rutherford found out that there was a compact nucleus --
in fact, he found out *because* he was getting rare, askew data points that fell far away
from the mean.
Once at Manchester, Rutherford found a well-equipped laboratory. He also found a
25-year-old physicist named Hans Geiger. Geiger had been Professor Schuster's assistant.
When Rutherford took over, Geiger agreed to stay and work with him on alpha particles.
Together, Rutherford and Geiger developed a detector that could count alpha
particles. It was an early version of the Geiger-Mueller counter we use today.
Geiger used his counter to test a new way of detecting alpha particles. The new
detector was a screen coated with zinc sulfide. Each time an alpha particle hit the
screen, it would emit a tiny flash of light called a scintillation. In order to see the
scintillations, Geiger had to peer at the screen through a microscope.
Now Geiger was ready to do an experiment. Rutherford had noticed that when a beam
of alpha particles passed through a thin foil, its image on a photographic plate was
blurred. The alpha particles were colliding with the atoms in the foil, and bouncing off
at a small angle. When a beam of particles interacts with a target in this way, it is said
to be scattered. Rutherford and Geiger hoped to learn something about atoms by counting
the scattered particles.
Geiger got his alpha particles from a radioactive "source." To create a
narrow beam of particles, Geiger placed his source behind a slit. Fifty-four centimenters
from the slit he placed a zinc-sulfide detector. The alpha particles emerged from the slit
and hit a spot in the center of the detector.
Geiger put a thin foil in front of the slit. The alpha particles went through the
foil, but they did not come out in a narrow beam. They spread out like light from a
flashlight.
Geiger moved his detector across the beam. At each new spot he counted the number
of alpha particles hitting the screen. From his measurements he calculated the average
angle of deflection of an alpha particle that had passed through the foil. It was very
small, less than one degree from the center path.
At about this time, a student named Ernest Marsden joined Geiger at the lab.
Geiger asked Rutherford to suggest a project for the young man. Rutherford told him to see
if any of the alpha particles were being deflected by more than 90 degrees. That is, he
was to see if any alpha particles were bouncing back toward the source.
A few days later, Geiger reported that Marsden had indeed observed alpha particles
deflected by more than 90 degrees.
Rutherford was dumbfounded. From Geiger's measurements, he knew that the
probability of small deflections adding up to more than 90 degrees was less than one in a
billion. Yet when Geiger and Marsden counted alpha particles, they found that about one in
8000 was deflected by a large angle.
Rutherford could think of only one explanation for Marsden's result. The alpha
particles must be colliding with something small and heavy inside the atom.
Hantaro Nagaoka had been right. The atom's positive charge was concentrated in the
center, with the electrons in orbit around it. The small, heavy center of the atom is
called the nucleus, from the Latin word meaning kernel, or small nut.
When Rutherford was told about the result (> 90 degrees) he said,
"It was as though I had fired a high-caliber bullet at a thin sheet of tissue paper,
and the bullet bounced back into my face!"
Those pesky data points.
Of course, the above historical story has nothing to do with the
snowbird.
Whatever ... later ... Charlie.

I primarily wanted to know "who started it?" What guy, or guys, started all the
crap between Ireland and Britain?
>I read one book after another and each time I would think, "Ahh...here is where
it started. If that jerk had just kept his mouth shut and his hands off other people's
property...." and then I would read where something had happened further back and
that was not the cause...this new thing was.
>I had to go as far back as quasi-reliable history would permit. I might have dug more
into the "Irish Question" than on anything I have shoveled through.

as simple as I really, really wanted it to be.
The stuff you write is more interesting than many of the other
books on the same topic, because you take a fresh look at things. Often it is a
controversial look, but that's OK.
I believe, seriously, that you should consider writing a book
about Britain and Ireland (which will also unavoidably include the Danes, Norwegians,
Franks, germanic folks, etc.). When you spend so much time typing these things up for
e-mail, you really should save them and gather them together and proofread them. (Unless
of course you just don't want to write a book on the subject -- but hey, isn't it just
about your most favoritist subject?)
If you wanted to do this, I would be willing to proofread for
you. I know Bettie does that, but I think the more eyes the better. You make the
occasional typos as does everybody, but sometimes there are suggestions that I would make
about the way you say things -- sometimes I don't quite get what you mean, because you are
typing at near-light speed and you know what you are saying although the reader may not.
This, again, is true of all writers; that's why many eyes are a valuable resource. (And by
the way, you'd be hard-pressed to find a better grammar checker than I. That's one good
thing about Maryhelen, my housemate. She has a good ear and she makes very useful
suggestions about my writing. I usually take her suggestions. But she doesn't correct my
grammar, which is not in need of correction unless it's a typo; she does make suggestions
about style and word choice and what to say more or less about.)
Here's an example of something you wrote that is very
well put. This is an example of why I think you should write a book. You
wrote:
>These people end up on one end of the island and some on the other end.
On one end is soft rains, dew, an agreeable ocean with dumber than usual fish. There is
green grass, good soil, and if you want warmth, just dig up some dirt and light it. It
will get hot enough to boil water for whatever editable that one can force under the
boiling water. And the smoldering fuel even smells nice. In simplistic thinking...living
is good and it is easy.
>At the other end of the island, the angry waves continuly crash into rocky, craggy
cliffs. The rain comes blowing horizontally, cold and unfriendly. The ground is 6"
deep and then there are more rocks. Plowing is almost impossible and whatever grows there
has to like salty spray and continual wind. It is cold. They are always cold but if
getting too cold, they just have to cover up more...and these layers whip in the wind and
jerk them around. Standing still takes as much effort as walking. Walking into the wind is
exhausting. (I didn't know this until I spent a couple of days walking the north cliffs of
Cornwall.)
>In short, it is a miserable existence and creates a sense of long-suffering,
little joy, where only the brave and the mean will survive and they are fatalistic...what
will be, will be. The meanest will prosper.
You wrote: Dig up some dirt and light it. That's cute (but
of course, it's true). I learned about those winds across the pond when I went to the
cliffs of Maher. (sp?) At the time we got there, a big storm was blowing in from the
ocean, and I can guarantee you that those gusts of wind were hurricane force. No one would
have dared to walk to the edge of the cliff. To see straignt down, you crawled on your
belly and snuck your eyeballs over the edge. And it was evil cold (and wet). One girl was
running downhill into the wind (not close to the edge) with her arms extended and
flapping. She was trying to take off. It didn't work, but we got a picture of her. (My
wife took the picture, along with almost everything else.)
Re. anthropologists and archaeologists: I have no problem
calling them "scientists" at all. The ones that I will not call scientists are
the practitioners of computers, sociology, psychology, and education. Education degrees
are such crap. I've told you about the five things that must be done to save education in
this country, four of which I know how to do and the fifth I do not. But one of the ones I
do know how to do is immediately eliminate any requirement for "education
courses" to be allowed to teach. The education bureaucracy is as maddening as the
government bureaucracy. It's like believing that taking courses can teach you to write
like Shakespeare.
See, you don't wanna get me started.
Go work on a book. I think I'll do the same, as soon as I
finish reading this book about on-line teaching and then order some software. I have
finally given up. The whole imbecilic world is so slavishly addicted to that bag-of-dirt
bad joke called MS Word that I am having to break down and buy it. I still won't use the
thing -- I cannot even make it work properly. I'll use it only to check WordPerfect's
conversion into Word format to see that it is correct.
Later ... Charlie.

>I do not read escapist literature unless it was written
by Tolkien, Jerome, or Wodehouse. Really. I would not waste my time on any
"scientific popular press." If it is AP, UPI, Reuthers, etc., and now,
unfortunately, BBC, it is show biz.
You should be more careful. Science magazine, like
Britain's Nature magazine, is one of the most prestigious journals in the world, and is
read by most Ph.D. scientists. Most "educated" non-scientists in this country
would be unable to understand it at all. The second half of the journal is so difficult to
read that people with Ph.D.s in a field of science other than the field of the article
(e.g., a physicist reading an article about chemistry) say that even they have difficulty
understanding what they are reading. This is NOT "scientific popular press".
AP, UPI, Reuthers, etc. are jokes. The only place I know to
get good general news is the New York Times. And it's tottering on the brink. They just
recently reduced the page size, for dumb-down show-biz reasons. The number of pages stays
the same, so now the articles will not be as long. This is good for most people, since
they don't have long enough attention spans to read those long, serious, boring articles
that are hard to read and that make you have to think. I just remembered that for a while
somebody was publishing a "newspaper" -- I don't remember where or how I came
across it, but I certainly didn't buy it. It was called something like "Happy
Times". Every single article in it were intended to make you happy. No wars, no
politics, no famines, no plane crashes. I was just insipid vapidity about cat being
rescued from trees and people winning the lottery and beautiful new churches being built
and babies being born.
Gandhi walked a lot with bare feet, so his feet
were caloused, and because of his vegetarian diet he was rather sickly, and he had bad
breath. Hence, he was a super-caloused fragile mystic plagued with halitosis.
Until next time ... Charlie.
