Hi Horace,

Thanks. I have now derived the formula for myself, so I understand
where it comes from, and what the various constants mean. I have
also applied the same derivation principle to an active vortex
that it constantly being topped up to maintain a constant level.
The result for a vortex with no initial angular velocity can be
found at
http://users.bigpond.net.au/rvanspaa/vortex-shape.mcd
and
http://users.bigpond.net.au/rvanspaa/vortex-shape.gif

I'm still thinking about how to correctly introduce an initial
angular momentum. I may try it with a fixed angular velocity at
the rim, and see what happens. (This is what one would get with
tangential addition of water as in one of your previous drawings).

BTW the initial restriction imposed on the angular velocity by the
radius needing to be less than the drain radius doesn't appear to
be serious. IOW even an initial angular velocity that produces
just a slight dip in the surface would already be sufficient to
yield OU according to the first document I posted.
However, I'm now having second thoughts about the validity of that
first document (http://users.bigpond.net.au/rvanspaa/vortex.gif).

The variable h is the distance up from the bottom of the tank in the

Feynman's *Lectures on Physics*, Vol II, 40-10 ff, namely:

   h = k/R^2 + h0

takes h in the downward direction.  However, Feynman's equation and

Great analysis.
It should work IMO even if the forces are as Ampere states unless there 
is no displacement current, in which case the closed end would be 
balanced within it's self, and the open end would have no force.

Your analysis makes it tempting to try and build it, except that in air 
there really is a displacement current due to polarizing the air.
A force would certainly be generated no doubt, but so would a stream of 
moving air.

Of course maybe a better design would be to look at it from the point of 
view of the displacement current.
Instead of trying to cheat Newton by creating an open circuit, we should 
be trying to use the vacuum as a propellant. (it would still be an open 
circuit but the focus would be of applying force to the vacuum)

I'm not sure but I think this line of reasoning is only profitable if 
you assume Ampere longitudinal forces exist in which case the force is 
not created at the closed end but by the longitudinal forces on the 
'rails' at the open end.

The magnetic field which is currently created by a one turn open coil 
could instead be provided by a multi turn coil.
Imagine a hoop coil with the two wires leaving the coil at the right and 
left, necessarily either the top or bottom must have one extra half turn.
The wires are connected to capacitor plates, one on the right one on the 
left.

This would significantly lower the operating frequency and probably 
lower radiated fields.
Increasing the magnetic field is the same as increasing the strength of 
the magnets in a dc motor.
As the vacuum is being polarized (the displacement current is flowing) 
it's motion through magnetic field thrusts it rearwards.

The stronger the magnetic field created by the coil, the stronger the 
effect the magnetic field created by the vacuum displacement current has 
on the coil.

I do have a concern with your diagram though, if you go from wire or 
coax to plates the current branch out to fill the plates.
The problem is that the currents branching out should create a force in 
the opposite direction this becomes more clear if you substitute the 
capacitor plates with wires.
But what can be done is to use the same metal you use with the plates 
with the same width for the whole construction (except the the toroid 
and wires leading up to it, doesn't matter that they are thinner as the 
currents must both converge and diverge going in and out.

The interesting series of posts regarding this subject is fascinating. 
Anyone sitting in the middle of a tornado or hurricane can testify that the 
forces generated are awesome and certainly didn't come from the effect of 
gravity of falling water. A water vortex performs an interesting " reverse" flow 
similar to a hurricane. The evidence of this reverse flowing condition is from 
the micro 
"twisters" spun off from the main vortex. The twisters are described as 
microbursts by the weathermen and account for the strange and specific damage 
during a hurricane. The twisters produce a short durationwhistling sound 
easily remembered by anyone that has spent hours located in the path of a 
hurricane as it passes.
We can produce many variations of a vortex in our glass test tanks, The 
short duration vortexes spun off from the center vortex can be vertical, 
horizontal or diagonal and visible in the water tank because of entrained air.

...sure, but...

The problem of overlooking very significant incidental
'problems' to prove a point goes ways ;-)

The refining of the structural materials for windmills, or
the silicon for solar cells, are both dirty processes
which demand lots of coal (unless nuclear is substituted as
the source of energy for refining. These energy sources also
create huge secondary environmental problems because of the
tonnage of discarded ore and coal emissions  - all the more
so because these end-processes, wind and solar, are of
relatively low energy density.

Has anyone ever calculated the environmental burden to the
ecology caused by the tons of steel required for a windmill?
My bet is that if this is done, nuclear will look very
favorable in comparison because of its extraordinarily high
energy-density, compared to these two, which are low
energy-density.

But again, the issue should not be framed as either--or
when it comes to these three very desirable energy
resources -- as we need all the extra solar, wind and
nuclear we can put in place - but in the proper balance, as
they are ALL highly preferable to burning fossil fuels.

IOW let's do a total energy balance, realizing that when we
strip mine coal to make lots of silicon, then the few ppm or
natural radioactivity in the coal (or natural gas) get
dumped directly into the atmosphere in small particulates
where it can do the most harm. In terms of cancer risk, the
burning of coal is infinitely more damaging to humans than
having a moth-balled nuclear plant, which releases nothing
into the atmosphere, or the occasional Three Mile Island,
which posed a de minimis risk to health.

My contention is that it is futile - and really
counter-productive for the dedicated proponents of wind
and/or solar energy to fight nuclear. These people should be
allies, not adversaries.

This unfortunate situation cause confusion which is playing
directly into the hands of the petrocracy.

Instead, environmentalist should unite - and realize that
yes, nuclear is a good, if not the best, overall
environmental option- and all ought to be joining together
and combining resources against the real enemy: which is
fossil fuels, and especially coal.

IMHO the best thing to do with coal is to convert it into
carbon structural fiber and use that fiber to replace steel,
which cannot be made without coke - which is an extremely
dirty and damaging process. The best thing to do with
natural gas is to likewise convert it into plastics. Use
wind, solar, and nuclear to provide the energy to do the
conversion of these - and everybody is happy (except the
steel mills which have mostly moved to China anyway).

ignoring the fact that the real accident, as it occurred in the
real world that you and I live in, was due to technicians shutting
off all of the fail-safe systems and intentionally driving the reactor
to failure. Could the reactor have been designed better? Sure.
In fact, the current reactor could be redesigned so it is
impossible to override the failsafe systems. You could
weld the switches closed, although eventually someone would

with a pair of side cutters. Here in the real world, humans
do these things. In the idealized world of Mark Mills,

The author also claims that, opposed to the former SU, we _can_ build
a safe toaster oven. I have a toaster oven in my kitchen, produced
by the American company Black and Decker. It was recalled due to
the design being inherently unsafe; the heating element is placed
right below the door so when you reach in for your toast, you
can burn the top of your hand. I'm careful now with the oven, and never
got around to returning it, but just about everyone who uses
it gets burned at some point. In the UberAmerica of Mark Mills,
my toaster has never existed. All products here work perfectly,
as do our power generation equipment. Perhaps Mark was out of
town last summer when the grid failed and a few million New Yorkers
had to walk back to Brooklyn in the dark. Maybe he was on a GE funded
junket to Thailand???

If the author thinks that nuclear power is safe, he should open an

That's not true. You can use electricity from windmills or silicon to
refine the materials needed to make more windmills (or solar cells). The
only thing you need coal for is to convert iron ore to steel, but you
need this with a nuclear reactor too, and nuclear reactors use much more
steel than windmills do, per KW of capacity.
Furthermore, the energy payback time for a wind turbine is the lowest of
any conventional energy source. It takes about 3 months for a wind tower
to produce enough energy to manufacture another tower. It takes about 6
months or a year for a fossil fuel, and about 2 years for a nuclear
plant. Wind towers will probably last much longer than conventional
plants; 100 years versus 20 to 50 years. (The turbine engines and blades
will last ~20 years, but the tower consumes most of the construction
energy.)
Solar cells are much worse. Some do not pay back at all. Others take
about half the total useful lifetime of the cell to pay back. Solar cells
should be thought of as batteries rather than a source of energy.
However, it is the silicon that is energy intensive, and it is mostly
scrap silicon from the computer chip business, so it would be thrown away
otherwise. You might compare this to burning waste from computer chip
factories (except that it produces no pollution, of course). If solar
production expanded there would not be enough scrap silicon.

These energy sources
also
create huge secondary environmental problems because of the
tonnage of discarded ore and coal emissions - all the more
so because these end-processes, wind and solar, are of
relatively low energy density.
Wind has high energy density. A large modern wind turbine generates up to
10 MW, as much as a large helicopter engine, or twice as much as a modern
railroad locomotive. Comparing the footprint of the wind
tower, this is the highest energy density of any energy source. Comparing
the 3-dimensional mass of tower or the number of tons of concrete gives a
different answer, but this not relevant. Measured in useful land, the
footprint of offshore wind turbines is zero. All of the electricity and
all of the automobiles in Europe could easily be powered by offshore wind
in the North Sea. Wind in the U.S. could easily generate more energy than
all of the oil fields in the Middle East now do, even with today's
technology, and much more with ultra-high towers. The mid-east oil fields
are not at peak capacity, with no reserve, and they will soon begin a
rapid decline, whereas U.S. wind resources will last as long as the sun
shines.

Has anyone ever calculated the
environmental burden to the
ecology caused by the tons of steel required for a
windmill?
Yes. This has been done extensively. Mark Mills and others have
misrepresented these calculations, especially by claiming that wind
turbines kill birds. Actually, thermal generators (coal and nuclear) kill
millions of birds, whereas nobody has ever seen a modern, tall, slow wind
turbine kill a single bird. Birds are evolved to avoid things like
turbines and trees waving in the wind. They did not do well with 1970s
vintage wind turbines with low, rapidly turning blades, but they have no
difficulty avoiding the big ones.
Aircraft of all sorts also kill millions of birds, and birds sometimes
destroy aircraft. See:

NO NO NO !!!

Just to clear up one major point and continuation of a line
of disinformation put out by the Soviets. The Chernobyl
reactor design - and not the irresponsible acts of the
employees - caused the accident. You are falling for the
same bogus story put out by the Soviets to protect their
other reactor assets - also flawed from day-one. And make no
mistake, the immediate cause of the accident was worker
stupidity but the accident was absolutely inevitable, given
the flawed design (now changed). We were actually taught
this in the 60s as part of a reactor design course. The US
considered but rejected this design in the 50s (it is a
cheaper design and needs far less enrichment the PWR).

This Soviet design has a fatal flaw in that the coolant
(light water) is NOT the moderator. The moderator - carbon -
has far less thermal neutron cross-section than does the
coolant, so in a loss-of-coolant accident, your reactivity
goes way UP instead of down, and exponentially fast, it
should be added. In all US designed reactors,
loss-of-coolant shuts the reactor down because the coolant
IS also the moderator: HUGE difference.

We even told this the Soviets this back in the 60s in great
detail - yet they persisted with a totally flawed design
because it was cheap, plus they did not educate the workers
well enough about the fatal consequences of loss-of-coolant.
In a US reactor, this loss would shut the reactor down over
time, as it did at TMI but in their flawed design, loss of
coolant exponentially increases the reactivity of the core -
and failure is guaranteed.

This fault goes straight back to the Soviet bureauracracy
and their lack of accountability for anything other than the
lowest-cost solution- and not exactly to the workers
themselves, however stupid their actions were (and they were

The only solution then becomes to encase the whole works

rail-car sized reactors, intead of one large one, then these
can be encoffined on site, after they reach full maturity
(75 years) and the same plant can continue operating for
many hundreds of years.

remains that it took human hands to turn off the existing fail safe
equipment, and destructively test the reactor. NO ENGINEERING
DESIGN CAN WITHSTAND THE HUMAN HAND. All machines will
fail in the end, because humans are smarter than machines
and can think of utterly ingenious ways to break them.

The immediate cause of the accident is all I care about, frankly.
Because that's what caused the accident. You seem to think
we can defeat Godels Law and build a machine that is impossible
to break. The rest of the reactors adjacent to the destroyed
reactor have worked fine to this point, because no one
has ( yet ) shut off all the safety overrides and tried
to destructively test the reactor again. But it's a matter
of time...

Here's a more recent example. The last nuclear accident
in Japan occurred when workers processed uranium fuel
rods in a steel mop bucket!!! They put in enough material
to reach critical mass, which caused a small explosion.
Now perhaps Japanese mop buckets can be redesigned with
a special radiation sensors that alerts the user when
he's put too much uranium in the mop bucket for processing.
Or better still, a lid which prevents the insertion of
uranium fuel rods. All these things would help, as
you say about the SU designed reactor. But what caused
the accident? And how will all our careful designs
help solve the problem? Don't you think the workers
would have cut the wires to that annoying alarm they
keep hearing when they load the bucket with uranium?
Or unscrew the lid? What the hell are they doing
processing uranium in a mop bucket!!! At what point do we admit PBKAC,
as we say in the software industry, ( Problem Between Keyboard And Chair ).

I'm all for nuclear power, it's a great source of energy.
The problem is these pesky primates we have to rely on to
run the plants. How do we redesign them for safety?

Keith,

 Here the author implies that the Chernobyl accident was
due to some major fault in the reactor design and
implementation, carefully ignoring the fact that the real
accident, as it occurred in the real world that you and I
live in, was due to technicians shutting off all of the
fail-safe systems and intentionally driving the reactor to
failure.

NO NO NO !!!

Just to clear up one major point and continuation of a line
of disinformation put out by the Soviets. The Chernobyl
reactor design - and not the irresponsible acts of the
employees - caused the accident. You are falling for the
same bogus story put out by the Soviets to protect their
other reactor assets - also flawed from day-one. And make no
mistake, the immediate cause of the accident was worker
stupidity but the accident was absolutely inevitable, given
the flawed design (now changed). We were actually taught
this in the 60s as part of a reactor design course. The US
considered but rejected this design in the 50s (it is a
cheaper design and needs far less enrichment the PWR).

This Soviet design has a fatal flaw in that the coolant
(light water) is NOT the moderator. The moderator - carbon -
has far less thermal neutron cross-section than does the
coolant, so in a loss-of-coolant accident, your reactivity
goes way UP instead of down, and exponentially fast, it
should be added. In all US designed reactors,
loss-of-coolant shuts the reactor down because the coolant
IS also the moderator: HUGE difference.

We even told this the Soviets this back in the 60s in great
detail - yet they persisted with a totally flawed design
because it was cheap, plus they did not educate the workers
well enough about the fatal consequences of loss-of-coolant.
In a US reactor, this loss would shut the reactor down over
time, as it did at TMI but in their flawed design, loss of
coolant exponentially increases the reactivity of the core -
and failure is guaranteed.

This fault goes straight back to the Soviet bureauracracy
and their lack of accountability for anything other than the
lowest-cost solution- and not exactly to the workers
themselves, however stupid their actions were (and they were
*stupid* beyond all comprehension but yet that was not the
ultimate problem).

The price has fallen from $40 to $20. These are not very bright. A slightly 
larger version would be ideal for Third World house.

I believe this is the ultimate development of the household flashlight. It 
will never be fundamentally improved in the future. Flashlights 200 years 
from now may be a little brighter, smaller and lighter, and perhaps 
longer-lasting, but they will still be about this big, and they will still 
be hand-powered. When you need a flashlight to walk the dog or put out the 
garbage, you do not want one that is blindingly bright, like an automobile 
headlight. Hand-powered LEDs provide a convenient, useful level of light, 
so I doubt anyone will replace hand power with a battery or a cold fusion 
generator. Cold fusion would be good for a large, powerful flashlight, such 
as one used by rescue workers searching for a child lost in the woods.

Ultimate technology is rare. Most machines can be improved, and will 
evolve. Examples of ultimate technology in daily life include spoons, 
buttons on shirts, and the 4-function solar powered calculator. Of course 
we make more complex calculators for some purposes. But for simple 
arithmetic and the quick estimates we used to do with slide rules, I doubt 
the 4-function calculator can be improved upon. Buttons on a shirt can be 
replaced with a zipper or Velcro, but there is no real advantage.

Like in science, the conclusion one reaches depends on the assumptions 
made at the beginning. The beliefs of each religion and the rules 
supposed to be God-given suffer from this same limitation.

In this article the author makes the argument that the rules of the 
Catholic Church, i.e. no abortion, no condoms, and no gay marriage, 
would not advance mankind because their change would separate the sex 
act from its primary intention, thereby causing injury to mankind.

The fact not considered is that all three prohibitions would lead to a 
smaller population.  The assumption not considered is that this fact 
might be a good thing.  Providing a growing Catholic population has 
always been the self-serving policy of the church.  For centuries, this 
policy gave an advantage to the human race.  However, this advantage is 
rapidly decaying away as population grows at a compounding rate.  How 
many more people must suck the resources out of the earth before the 
Church changes its policy? I suggest that even science can not mediate 
the damage if population grows at a sufficiently rapid rate.

Why progressive Westerners never understood John Paul II
By Mark Steyn
(Filed: 05/04/2005)
If I were Pope - and no, don't worry, I'm not planning a mid-life career change - but, if I were, 
I'd be a little irked at the secular media's inability to discuss religion except through the prism 
of their moral relativism. That's why last weekend's grand old man - James Callaghan - got a more 
sympathetic send-off than this weekend's. The Guardian's headline writer billed Sunny Jim as a man 
whose consensus politics were washed away in the late 1970s. Is it possible to have any 
meaningful consensus between, on the one hand, closed-shop council manual workers 
demanding a 40 per cent pay rise and, on the other, rational human beings? What would the middle 
ground between the real world and Planet Zongo look like? A 30 per cent pay rise, rising to 40 per 
cent over 18 months or the next strike, whichever comes sooner?

By contrast, the Guardian thought Karol Wojtyla was a doctrinaire, authoritarian pontiff. That 
doctrinaire at least suggests the inflexible authoritarian derived his inflexibility from some ancient 
operating manual - he was dogmatic about his dogma - unlike the New York Times and the Washington Post, which came 
close to implying that John Paul II had taken against abortion and gay marriage off the top of his head, principally to 
irk liberal Catholics. The assumption is always that there's some middle ground that a less 
doctrinaire pope might have staked out: he might have supported abortion in the first trimester, say, or 
reciprocal partner benefits for gays in committed relationships.
The root of the Pope's thinking - that there are eternal truths no one can change even if one wanted to - is completely incomprehensible to the progressivist mindset. There are no absolute truths, everything's in play, and by consensus all we're really arguing is the rate of concession to the inevitable: abortion's here to stay, gay marriage will be here any day now, in a year or two it'll be something else - it's all gonna happen anyway, man, so why be the last squaresville daddy-o on the block? 

We live in a present-tense culture where novelty is its own virtue: the Guardian, for 
example, has already been touting the Nigerian Francis Arinze as candidate for 
first black pope. This would be news to Pope St Victor, an African and pontiff from 
189 to 199. Among his legacies: the celebration of Easter on a Sunday.
That's not what the Guardian had in mind, of course: it meant the first black pope since the 
death of Elvis - or however far back our societal memory now goes. But, if you hold an office 
first held by St Peter, you can say been there, done that about pretty much everything 
the Guardian throws your way. John Paul's papacy was founded on what he called - in the title of 
his encyclical - Veritatis Splendor, and when you seek to find consensus between truth and lies you 
tarnish that splendour.
Der Spiegel this week published a selection from the creepy suck-up letters Gerhard 
Schröder wrote to the East German totalitarian leaders when he was a West German pol on

2005-04-05 Thread John Robertson
I have been a lurker for years now and have enjoyed the discussions 
very much. I am an innumerate linguist, unprepared to comment on much 
of the technical details of these discussions. I would, however, like 
to emerge from my years of lurking to comment (of topic) on Jed's 
statement:

snip
Throughout history, capitalists have sacrificed millions of lives and 
their own futures time after time with stupid, self-destructive 
behavior. This is human nature. Capitalism is the most efficient way to 
allocate money and resources, but it does not promote morality or human 
decency any more than communism does. It is an amoral economic system. 
Engineering is the most efficient way to build machinery, and it is 
equally amoral. It works just as well whether you build lifesaving 
machinery or instruments to torture people with.
and snip

The question of morality is an interesting one. English has three 
terms: moral, immoral, amoral. Taken by themselves the words have a 
positive, negative and neutral connotation. The referents to which the 
words might attach, however, are another issue. What was immoral for 
Stalin's Communism, might have been fine and dandy for Roosevelt's 
democracy, and vice versa. The real question is if there is a basis for 
determining morality independent of Stalin's communist culture or 
Roosevelt's capitalist culture. There seems to be an overwhelming if 
not universal sense, for example, that incest is neither moral, nor 
amoral -- Egyptian and Incan  practice of marriage (kings and queens) 
not withstanding. In general, we humans have a hard time believing that 
wanton murder for selfish and personal gain is acceptable behavior. 
These may well be examples of behavior that the majority of the human 
race might describe using immoral (whatever the term for 
unacceptable behavior).

However, since there is so much gray area in determining behavior that 
is moral, immoral, or amoral, I have to believe that it is impossible 
to persuade anyone with fixed beliefs to change. Therefore, I doubt 
that this will persuade Jed: (a) It is harder to dismiss communism as 
an economic system from communism an ideo-political system than it is 
to separate capitalism as an economic system from capitalism as a 
political system. It is fair to say, I  believe, that capitalism, past 
and present, encompasses more diversity of political systems than 
communism ever did. (b) If we are to believe the The Black Book of 
Communism: Crimes, Terror, Repression  (by Stéphane Courtois, Nicolas 
Werth, Jean-Louis Panné, Andrzej Paczkowski, Karel Bartosek ...), the 
behavior engendered by Communism in the 20th Century was directly and 
indirectly responsible for the deaths of from 80 to 100 million people. 
I find such wanton, selfish killing immoral. I may be wrong, but I do 
not believe that as many people who suffered in Jed's thrall of 
capitalism in the same century were killed for the same wanton, selfish 
reasons. One might argue that the flourishing of technology helped more 
people under capitalism than it did under Communism.

It is probably fair to say that what we believe is what we are willing 
to act on. What we choose to believe really does matter to our future 
and more importantly, to the future of others as well. The data seem to 
argue that communism -- a belief system that prompted wanton, selfish 
destruction of human beings -- is hardly amoral.

Speaking of legendary computer (and punched card) stories the one I'll never

around 1979 I was compiling another object code deck (IBM cards) from an 
assembler language program on an IBM 360-20 with 32K of memory, 30 megabyte 
hard drive. I miss-keyed one of the address locations, creating a syntax 
error. I was bummed because I knew it would take another 30 minutes for the 
computer to punch out another deck of object code, just to correct the one 
miss-keyed address location. FEAR NOT said the older programmer. Since we knew 
what the actual hexadecimal address was (by looking at the cross reference 
listing) he took me over to the keypunch machine and punched out a new object 
card containing the correct hexadecimal address. He then took me over to the 
object deck and unceremoniously replaced the erroneous card. Time spent fixing 
my syntax error: 5 minutes.

He could have performed the trick even more quickly but he was teaching me.

The older programmer has since made his transition to the next dimension, but 
I'll never forget the delight he gave me in this simple lesson: Human speed can

I know nothing about religion, but I know plenty about AIDS, population,
effective disease prevention strategies and so on, and this is incorrect.
I agree that education and promoting responsible sexual behavior have an
important role to play, but policies that do not make effective use of
condoms will condemn millions of people to gruesome death for no reason,
and leave millions of orphans who will starve. Most of the women with
AIDS in Africa are faithful to their husbands, but husbands in Africa
have *never* in faithful to wives. They never have been in recorded
history, and they will not start now.
Whatever good the Pope may have done, it was outweighed by his opposition
to contraception and the use of condoms.
Overpopulation is the worst crisis of the 21st century. Because the world
is overpopulated (or to put it another way, because our food-production
technology is so destructive and inefficient), the world's resources and
land are being ravaged and two billion people live on the edge of
starvation, in unthinkable misery. *THAT* is a morality problem. What
people do with their sex organs is mostly their own business. (The only
sexual behavior that bothers me is pedophilia, and the only major
organization guilty of countenancing it on a large scale is the Catholic
Church, as it happens. The Pope looked the other way for a long
time.)
If cold fusion can be perfected and agriculture eliminated then the world
will support a higher human population without damage to the ecosystem.
In that case, contraception will be a little less important for a few
decades. But in the long term it is essential. We cannot sustain
exponential growth.
Population will never come under control until effective contraception,
education for women, child care and old-age pensions are put in place.
Mumbo-jumbo about changing behavior will accomplish nothing. People never
behaved differently than they do now. I have never heard of a society in
which most teenagers were abstinent. In the US teenage pregnancy rates
have been unchanged since colonial times. The only reason pregnancy is
declining now is because of the increased availability of
contraception.
I do not go along with this idea that Grimer and Pope endorse, that we
should go around lecturing Africans about their sex lives. People can
decide for themselves how they should behave, and what they consider
moral. They need no help from us. They do not want lessons in morality
from us. If they feel like engaging in depersonalized sexual games, the
way ancient Romans, Japanese and Chinese people did, that is entirely
their call, and their business. As mayor La Guardia said of the Pope:
you no play-a the game, you no make-a the rules.

I know nothing about religion. It seems synonymous with superstition, as
far as I can make out. The Pope claimed that the assassination attempt
against him was prevented by a dead person, St. Mary, who deflected the
gun. I expect he believed that a virgin conceived and bore a child.
People who believe in ghosts, biological impossibilities and similar
weird notions live in a different world than I do. They are as distant
from me as the primitive tribes in South Pacific islands or pre-modern
Japanese peasants. I have studied the Islanders and the Japanese. I know
a lot about them. I sympathize with them. I admire them, and their
culture, arts, and languages. I like their sexual morality, which the
Pope would not approve of. But despite my wholehearted admiration and
knowledge of them, there is an unbridgeable 400-year gap between us,
starting with Francis Bacon and Isaac Newton. The Pope stands on the
other side of that gap, mired in pre-modern, pre-scientific
darkness.
Despite all the pleasant rhetoric and high-minded people who claim there
is no conflict between science and religion, it seems clear to me that
there is. It is no coincidence that most scientists are atheists
(according to the Scientific American and other sources). T. H. Huxley
was the first scientist to openly champion science against religion.
Everything he said seems correct and up-to-date to me. Religion offers
certainty without proof, just the opposite of science. It asks people to
believe in fabulous nonsense such as a virgin birth, Noah's Ark, bringing
people back from the dead, curing diseases by hocus-pocus and
faith-healing (which is to say, blaming the patient for the disease), or
changing primate sexual behavior such as homosexuality. I cannot imagine
how a sane, educated, modern person could believe such things, but some
people do, including many of my friends. Perhaps I lack imagination. I am
glad I do! Frankly, I cannot see why anyone would even *want* to believe
in these things. They are nightmares, even as myths.

Some of the ecological damage from overpopulation is permanent. However,
results from many different societies have shown that science together
with enlightened social policy can reduce or even reverse population
growth. This can happen remarkably swiftly, sometimes in a single
generation. It is much cheaper it used to be. In the 1960s some experts
worried that we would not have enough money to distribute contraception.
Others worried that traditional societies would resist the changes, or
that village health care providers and women would not be skilled enough
to use it. Of course money is a problem, now mainly because the present
US administration refuses to provide it and wants to lecture people about
abortion and morality instead. There is resistance in some societies,
especially those mired in war such as Afghanistan. But there is less
resistance than many people expected. And it turns out Third World women
can take care of themselves as well as First World women can. (A
no-brainer.)
Contraception is essential, obviously, but not sufficient. As I said
before, three other reforms are needed: education and freedom for women;
improved health care for everyone, especially children; and old age
pensions. The latter two are essential because in many societies children
are the only security parents have in their old age. People who have no
children starve. Where there is no healthcare parents must have 7 or 8
children to ensure that one or two will survive.
As for education, it turns that women everywhere want education, money
empowerment and freedom. (Another no-brainer!) Low-cost Internet
connections in remote Indian villages and elsewhere are bringing it to
them in ways that would have been unimaginable 30 years ago.
The remaining problems are political, not scientific. The biggest
roadblocks, as far as I can see, are the Catholic and Muslim religions.
If they disappeared overnight I think it would be a big improvement. In
Europe, especially Italy, people ignore the sex morality of the Catholic
church. Let us hope they soon learn to ignore it in Peru and Brazil as
well. I am confident that they can and they will. People are much smarter
than we give them credit for.
Improvements in contraception were among the most important scientific
discoveries of the 20th century -- or indeed, of any century. They are
right up there with electricity, vaccination, anesthetics, and flight.
Most of the hard work was done in America, and we should take great pride
in this. I wish this history was taught in schools, but I suppose
students nowadays hardly learn about Pasteur or Edison. Much of the
research was conducted under the guidance and inspiration of Margaret
Sanger, with funds she scrounged together. Sanger was one of America's
greatest scientific heroes. I am inordinately proud of the fact that my
grandmother pitched in to help her financially and in other ways. It was
only a bit role in history, but look at the result! If cold fusion
succeeds I will have played a similar small but essential role. Sanger,
needless to say, fought a pitched battle with religion, just as Huxley
did. Humanitarians such as Sanger have brought a million times more
happiness, well-being, and solid, reality-based self-knowledge to people
than the Pope and all those other mystical mumblers tied together.
Nowadays many liberal religious people honor Sanger but they were no help
back then when she needed them. She had to fight them every step of the
way, just as CF researchers have to fight the DoE.

There is always a displacement current, even between vacuum plates.  The

regardless of the presence of a (non-vacuum) dielectric or not.  A little

identical to that from a conductor current, i.e the displacement current is
equal to the capacitor current.

Note: here interpret @ as the partial derivitive symbol below.

The capacitance of the capacitor is:

   C = epsilon A/d

where A is the plate area and d is the separation.  The conduction current
is then:

   i_c = C dv/dt = (epsilon A/d) dv/dt

On the other hand, the electric field in the dielectric, be it pure vacuum
or not, is, neglecting fringing (which doesn't occur significantly in the
coaxial version anyway):

   E = v/d

Hence:

   D = epsilon E = (epsilon/d) v

   @D/@t = (epsilon/d) v/dt

and i_d, the displacement current, is (D normal to the plates) given by
(now using D as a current density vector, S a surface envelope):

   i_d = integral over A{ @D/@t dot dS }

   = integral over A{ (epsilon/d) dv/dt dS}

   = integral (epsilon A/d) dv/dt=== typo corrected

   = i_c

so i_d, the displacement current, is always equal to the capacitor current i_c.

views and be forced to employ contraceptives or
abortion, then here is an alternative. If there is
someone who really wants to force that kind of control
on other people, then kindly do the following: get
yourself a gun, and shoot yourself now. You will have
accomplished what you set out to do: you have reduced
the worlds population by 1, and I guarantee you that
the cost of some contraceptives or an abortion is much
more than the cost of the gunpowder it took you to
blow yourself to hell.

There are more, but for the moment I am too pissed off
to handle them clearly. I am sorry if the tone is
extremely abrasive, I am very angry. And before you
judge me personally, keep this in mind. You don't know
me in real life, you don't know what I have been
through, you don't know who I really am. And just so
people know, I am not exactly what you would call a
religious man. You could call me a Christian, I do
believe in God, but I have my own views on things, and
lets leave it at that...if you judged me based on
seeing that word then you are not worth my time. But
I am also standing up in defense of the Muslims, Jews,
Buddhists, whoever.

Jed, you believe science and religion cannot coexist.
This isn't a belief, you are stating something as
fact. You are wrong in one case, at least. They
coexist just fine in the reality of my mind, if they
cannot work together for you in your reality, then
that is fine. Don't presume that just because you
can't make it work, no one else can.

Sorry if this offended anyone. But maybe it is time
those people who quietly keep getting offended
themselves say something.

Re: If I were Pope

Frank, Thanks for the post article by Mark Steyn

The word " consensus" describes the world view

Mark's comment ... "Thoughtful atheist ought to recognize" 
... Thoughtful ???
As the new century unfolds , the believer will be under an ever increasing 
attack.

My old Chem prof was a believer and was certain there is no conflict 
between science and believing God's word, the Bible.

We know so little science, have such little knowledge of creation except 
for what is seen. Consider we could be on the brink of a wonderful new world of 
science.. but .. alas! we are mired in the self .

I am better because Pope John lived and his teaching demonstrated God' 
truth. A man of courage of his beliefs.

OK, this is getting a little crazy-go-nuts.
1. Margaret Sanger was responsible for some good, yes.
She was also crazy. Not the kind of person I would
want to spend much time with. Very pro-eugenics. If
you support that, then congratulations, go build
yourself a private Gattaca. Leave me the hell out of
it.
The problem is that some people would be very willing to leave you and 
people with your belief system alone.  However, there seems to be an 
unwillingness of certain religious belief systems to leave the rest of 
us alone.
2. I am not pro-abortion for a few reasons.
A: It does nothing to encourage people to stop the
numerous meet and f**k flings.
Lack of abortion does not stop f**kings, which all the statistics and 
personal experience shows.

B: I wouldn't know if I was destroying someone who
might be something very important one day.
Or someone who was a mass murder.  Of course, if God wanted a person 
available to do something considered important, why would it matter if 
that body were destroyed?  Many more bodies would be available. Also, if 
God is all powerful and all knowing, why would a body that might be 
aborted be chosen?

C: I do not have to be pro-abortion just because you
say so. So many people have tried to force me to be
pro-abortion that I am now totally against it mainly
in defiance of those who would control my thinking.
Why do you think you are being forced to be proabortion and how is this 
done?  Of course, many people are being forced to be antiabortion just 
because the doctors are being driven out of business.
3. A religious person really really must have made you
mad once, Jed? It is fine by me if you are
anti-religion, do what you want to. But if you want to
try and say you and the anti-religionists are better
than anyone who has a religion, or worse force your
views on them via legislature, well, kindly knock the
hell off. 
I know of no proposed legislation that is antireligious.  However, I 
know that the religious right is trying to make gay marriage illegal.

You know, if we are supposed to be so
pro-women-liberation in other countries, so
pro-freedom, so pro-lets-all-get-along-as-equals, so
pro-insert theme of day here then why the HELL is it
ok and dandy to hate religion? 
I did not get the impression that Jed hates religion, nor do I. 
However, I do hate the attitude of certain religions in their belief 
that their God is better than the other God.

If you think I am
overreacting, then re-read your posts. They were
pretty damned irritating to me at least, and I am sure
others. Not for your opinion, that is fine. Do what
you want. But do not ever try to force it on anyone
else. By legislation or otherwise. This statement (the
last part anyways) is not directly aimed at anyone.
I would also like religious people not to force their beliefs using 
legislation, which is the common approach.
4. Contraception? Sure, why not. I have no problem
with this. But please, if anyone out there wants to
force the use of them on people who do NOT want to use
them, kindly take a hike. This statement is not
directly aimed at anyone.
As far I know, no one is forced to use contraception.  However, for 
awhile in this country and even now in some other countries, condoms 
were not easily available because the Catholic Church was opposed.
5. Are you guys actually reading this? I don't get

Does this quantify?

people. (I am not catholic, by the way, but I damn
sure respect them and am not going to say they are 400
years behind!) If this form of lack of respect for the
dearly departed is implicit in your atheistic-utopia

I think you miss the difference between respect and agreement with 
opinion and policy.  I respect the pope, but I think, for what its 
worth, his policy is harmful to humanity.  I respect you but I do not 
share your beliefs.

Why indeed?  I agree, we should be equal opportunity discriminators. :-)

GOD comes from the inside out; not the outside in.
Exoteric politics resides with the misidentification
of the spirit with the body. We are not the body.

If you are in the spirit of God, he gives you a sign.
This sign is the passing of a body. It is a symbolism
for us to follow as an example.

In this specific example I recieved my own dream, and
three days afterward the dream came to life. I am
working with that dream after the meaning was shown to
me. Knowledge is a free gift, you have only to be
receptive to recieve it. Perhaps it may come from your
guardian angel. Where-ever it comes from is
irrevalent. What is relevant is to say your
inspiration from the event.

In my case I could not understand what the dream
meant, but after the third day I began to see it. But
because I have no solid proof, I prefer to wait.
Perhaps the knowledge was only meant for me. Perhaps
others will not understand what the dream means. But I
will say it anyways...

I sought after some knowledge, and it was given in a
dream. It was up to me to interpret the dream
according to my pursuit of knowledge. For me the dream
was revealed in mathematics, according to my own
understanding, but it took three days for the
realization to set in. Now the next problem is how to
visualize what the mathematics mean for its analogy of
meaning when placed into reality.  Thats the tough
one. Something that was formerly considered impossible
was revealed, but without the dream, I would have
never considered the possibility.

An obstacle may be viewed as a mirage that limits us
by our own belief in it.

Let me just say and state a problem, and anyone else
is welcome to try. Perhaps you may think a computer is
necessary to solve this problem, but it should be
solved with just a paper and pencil. The dream
indicates to me how it should be solved in that
matter, and that is what the dream told me to do.
Perhaps if you had the powerful computer, it might
solve it for you, so I will make it harder, so that
you cannot use the computer to cheat. The dream did
not tell me where to start, but from the dream I 
determined where the starting point begins at.

This is just a simple mathematical problem then, and
from my understanding it does have a starting point,
which is the lowest point where it becomes possible,
or  what is  generically called the lowest common
denominator. If I gave that clue of the starting point
the computer experts might be able to solve it, but
perhaps this is not so great a mystery after all, and
maybe I am just stupid for giving the problem to begin
with: which for this reason I make the problem harder,
because it was given to me in a dream.

Create a magic cube. Say the numbers and spell them
out. Surely this is already known in the world of
mathematics. And surely I am making an ass out of
myself about saying about hidden knowledge; when
everything must have already been deciphered. But the
dream tells me how to decipher it, but IT hasnt yet
been deciphered by this author, but I see the
possibilities of how it should be deciphered. The
dream gave me a special unique understanding about how
the problem is solved. For me this is a miracle
because I had formerly analysed the problem and found
it to have no solution. It would take several days to
supply the solution with my pen and pencil: but
somehow; someway I glimpsed its possible solution: all
from the dream; And I COULD be wrong. That is what
faith involves; knowing that the answer exists. So
everyone else can take up this same challenge if they
choose, and supply that solution. For now I only say I
believe the solution exists because of faith in the
dream that was given.

So if you want an analogy for religion there it is.
The answer exists according to my intellectual
understanding, given by only a dream, and now you can
deal with the same problem; without the benefit of the
dream that shows the solution.

A magic cube is a magic square extended into three
dimensions. Take an ordered array of numbers in
sequential order, place them on a grid in three
dimensions so that the square becomes a cube: and make
every ordering appear to the outside observer to be
unity. The smallest magic square in two dimensions has
nine numbers. The random odds of finding the one
unique solution on the flat plane is about 4500/1. If
that were made into a magic cube it would have 27
numbers, or 3*3*3 elements, in three dimensional space
and then the square would appear in its 3-d analogy as
a cube.

Find ANY magic cube; if you think it exists. For many
years I thought a magic cube could not exist. But then
I had a dream; right after the pope died and later by
sustained concentration  from the dream I found that
it probably does exist. For me that was a miracle that
erased any doubt. And for all the Thomas the doubter
skeptics out there the answer when made is
