I'm an Olympian pagan

What's your opinion of the god Mars and his traditional affiliation with our planetary body of interest?

#652 Re: Not So Free Chat » Same-Sex "Marriage" - Carried over from the old 'Kerry' thread » 2004-09-21 11:00:55

Hmm...  Marriage laws came about as a means for the state to take over a role previously filled by religion.  Religion is already scurrying to catch up to modern reproductive technology.  Maybe it's time for the law to do so as well?

Incidentally, the comment was made that two (or more) people in a committed relationship don't need marriage to maintain that relationship.  I disagree on one point: they don't need the legal status of marriage.  Quakers, the Amish, old-school mormons and other groups get married without benefit of the law all the time.

I'll just do my stint in the Alabama National Guard. I don't think I'll be missed...

One weekend a month, two weeks a year, three years extended tour in Iraq.  Ain't the National Guard grand!

The chance to give every ME government the finger at once by voting for a Jewish president was irresistible.

You're in luck!  Re-electing Dubya would do the same thing _and_ free up the president's Saturday's.   :;):

Oops!  Wrote my last one before Gennaro accused all homosexuals of being child molesting perverts.  Sorry!   :laugh:

#656 Re: Not So Free Chat » Same-Sex "Marriage" - Carried over from the old 'Kerry' thread » 2004-09-21 07:23:44

Actually, Gennaro, contrary to what you might see on the news about high priced adoption agencies, there are still orphans and disowned children who go begging for adoption.  Whether homosexual marriages can serve a social reproductive function is very much dependent on whether they can adopt.  Allowing them to adopt would have a much greater impact than slight improvements in reproductive technology simply by virtue of the sheer numbers of children available for adoption, and serve a useful social function.

I do have misgivings about that, though.  It's been my experience that while a homosexual relationship can last as long as any heterosexual relationship, the average homosexual relationship lasts a much shorter time.  I'm not sure how the introduction of children will affect that.  If there's no change in relationship stability, I'd say don't let homosexuals adopt.  However, I've got no idea of whether that's true or not - no data. 

I guess I'm just going to sit back for now and let the great sociology experiment continue...

Which means we should have been and now need to be prepared to have troops there on a timeframe similar to Japan or Germany after WWII. It doesn't mean the fighting will last anywhere near that long, just that the work of remaking the nation will take decades and afterwards we'd do well to watch it and guide them a bit. It's a multi-generation project and I have no problem with that, it's what it takes. But the question is whether we have the stomach to finish the fight, the resolve to finish what comes after and the attention span to remember what the hell we're doing in the first place.

Good heavens, Cobra, we actually agree on a point of military strategy.  Who knew?   cool

For the record, I am one of those persons with all sorts of unreasonable objections to invading Iraq.  (I hadn't heard the one about Dick Cheney drinking the blood of Iraqi babies, but the tanker of crude pulling up nightly at his residence has been arousing my suspicions for a long time.)  It was arrogant.  It was without profit (but clearly not without profiteering).  It was foolhardy.  We should never have done it.

However, for those who haven't been paying attention lately, the question of US involvement in Iraq is no longer about whether or not we should invade. 

We must follow through on our actions, or we _and_ the people of Iraq will face far worse.  Unfortunately, that means hardship for us, and I'm not just talking about losing soldiers.  Rebuilding Iraq is going to take work, and lots of money.  If we don't pull out in the next year (possibly the next six months), the United States of American will have to reinstate the Draft to maintain its forces. 

And we can't pull out.  So, prepare to get drafted.

You guys just think old W has wronged you by making us look bad overseas.  Wait until he impresses you into military service and sends you personally.

#658 Re: Not So Free Chat » Same-Sex "Marriage" - Carried over from the old 'Kerry' thread » 2004-09-20 14:17:20

It is time to do a study to see if marriages last longer or common law relationships.

Arguably neither one in Louisiana.

This weekend we adopted an amendment to our state constitution that is supposed to prevent homosexual marriage.  However, it also calls common law marriages into question, meaning we're now set to have lengthy court battles over tort law that had previously gone unmolested for half a century. 

As for actually preventing homosexual marriage, the only difference this amendment will make is the creation of a budget line item for distributing updated copies of the state constitution.  Louisiana's existing laws against homosexual marriage were already iron clad.

*Sigh.*  In their eagerness to look good standing up to the homos, the banana republic of the United States has once again forgotten:  "If it ain't broke, don't fix it."

#659 Re: Not So Free Chat » Blair 'was warned of Iraq chaos' - words cant describe how im feeling..... » 2004-09-19 14:04:21

*shrug*  Well, the US and Britain are "in for a penny, in for a pound" now.  It is not practical to just withdraw at this point.

We broke it, now we have to buy it.

#660 Re: Not So Free Chat » Presidential Elections - ...and other political discussion. » 2004-09-19 13:59:21

Josh, I don't have an attention span long enough to understand all the political newspeak.  Issues alone are hard enough for me to follow.  Please excuse me while I raise my head up out of the sand for a few minutes and ask: 

What is a candidate's "travelling press"? 

(It sounds like there's some collection of reporters stuck riding around on the bus with these guys for months.  Poor saps... )

#661 Re: Science, Technology, and Astronomy » Traveling-Wave Engine - Deep Space Travel » 2004-09-19 13:44:25

Actually, as I understand it, this has NOT been around since the 1960's.  The newest advance described is the use of thermoacoustic cooling for greater efficiency, not the introduction of the Stirling engine.  (Although linear Stirling engines haven't been around since the 1960's, either.)  The cooling system is the neat part, not the engine.

The same principle could conceivably be applied to the thermocouples in a standard RTG, radiative cooling panels, or anything else that would benefit from a heat-engine refrigerator/cooling system with no moving parts. 

This is potentially a big advance.

#662 Re: Science, Technology, and Astronomy » Traveling-Wave Engine - Deep Space Travel » 2004-09-17 12:10:54

Hmmm... You know, this could be useful for a solar collector, too.  18% efficiency is pretty good for solar power generation, better than solar panels.

This use of thermoacoustic cooling/heating is pretty ingenious.

#663 Re: Mars Analogue Research Stations » MARS Spin-off's - Anything useful BEFORE the trip? » 2004-09-16 15:48:19

Have there been any notable and/or unique inventions developed for the Mars Analog Research Stations which might prove profitable if developed here on Earth?

Never trust any group of people who hang around with Lyndon Larouche.  Gotcha.  :;):  Get thee behind me, Larry!  big_smile

GCNRevenger, I concede that the scenario you described has been the case in the past.  However, I think the iron curtain between governmental and private sector space travel is coming down.  As implied in your earlier post, the key factor in this change is technology. 

Technologies and skills developed by government programs are becoming widely - and more cheaply - available in the public sector.  Formerly exotic techniques are becoming industry standards.  All that's necessary is the commitment to synthesize all of that new know-how into an enterprise. 

Unfortunately, "commitment" is often a euphemism for money and profit motive.  Those are currently lacking.  (It's a bit like leaping a wall and landing in a hole on the other side. sad )  However, one of the main reasons that there is no profit motive is that profit making ventures in space are almost as unexplored as the technology was thirty years ago.

#665 Re: Other space advocacy organizations » Zero-G Flights for Public » 2004-09-16 14:05:18

Also, all the touristy stuff in the private sector worries me for another reason:  Once enough people get killed or seriously injured, there'll be additional calls for stopping manned space exploration.

While I admit that the last thing I want to see before I die is not those Diet Rite ads plastered all over the Zero-G cabin, I also have to admit that I'm not aware of many people dying in a Vomit Comet.

This isn't going to open up the space frontier, but it's not hurting anything.  Let them play.

I prefer trained, experienced astronauts to private citizens doing stunts "up there" for now.

I would settle for trained, experienced citizens doing work if trained experienced astronauts doing stunts were not available.

#666 Re: Not So Free Chat » Presidential Candidates interviewed by Nature - Manned Space Exploration mentioned..... » 2004-09-16 09:00:41

*Sigh.*

Having already decided that I'm not psychologically suited to abstain from the coming US presidential election, I believe I'll ask if they'll allow me to bring dice into the voting booth.

#667 Re: Human missions » Politics for a new manned missions. - What politicans will do it? » 2004-09-16 08:41:06

You're right, comstar.  It would be a mistake to restrict this discussion to US politicians. 

Does anybody know who the most gung-ho pro-space legislators are in India's Parliament?  How about the Japanese Diet?

#668 Re: Martian Politics and Economy » All of you have it wrong » 2004-09-15 14:13:43

reverse election to decide which leading politician should be exiled for ten years...

Washington, DC would clear out like New Orleans evacuating for a hurricane!

#669 Re: Not So Free Chat » Gives me "the willies" » 2004-09-15 14:08:16

Egad!  Mobile and Biloxi were such lovely cities.  Shame they're not going to be there when I go back.   sad

So, male chauvinism is the answer to female chauvinism?  :sleep:  Not very original.

I don't get this.

Explaining this reaction to your earlier statements would take us off on an unnecessary tangent, Gennaro.  So, I'll just stay on topic and agree to disagree about which traditional Japanese gender role is more "deluded." 

Gender roles play an important economic role, particularly when times get as hard as Scott Beach and others fear they will, because they determine how a family's resources are allocated.  The traditional "working husband with housewife" model is at its heart an allocation of labor, not privileges, and who gets what privileges is (economically) irrelevant so long as the arrangement meets the demands for labor.  Modern society's contempt for gender roles of any type does have a cost in loss of available labor for the family.  While a few lost man-hours of labor may not be a problem in good economic conditions, it can make all the difference in the world when things get tight.

A return to traditional gender roles (actually, traditional allocations of labor) will make more man-hours of labor available for a family than it's usually given credit for.  A lot of traditional gender roles from various cultures are geared toward efficiency, not gender. 

Both spouses spending all of their time working jobs outside the home and leaving their kids in daycare full time (but not hiring a maid) is not typically the most efficient use of a family's labor.  Almost any other allocation of labor is more efficient than both spouses working full time, allotting no chores to their children and not contracting out for services.  The deeper the economy goes into the toilet, the rarer it will get.

Efficiency is more important than tradition in hard times.  But tradition can often point the way.

#671 Re: Not So Free Chat » Identify this Phenomenon » 2004-09-14 12:59:56

The APOD people seem to think the colors are caused by refraction in a special background surfacing material.  This is also a possibility.

#672 Re: Not So Free Chat » Identify this Phenomenon » 2004-09-14 12:45:04

It wouldnt be the Sun shining through something like the photographers glasses would it. It would explain the defraction at the edges and how the photographers shadow is dead center in the picture.

Ah, but no appreciable light would be refracted by the rims of the glasses, which would cast a clear shadow just like the rest of the photographer.

Where are the glasses?  They should be visible.

#673 Re: Not So Free Chat » Identify this Phenomenon » 2004-09-14 10:52:47

Okay, now that's interesting.

As for the explanation:

The picture is of the photographer's shadow, with the sun directly behind him/her.  The background is concrete - probably a parking lot, but exact location is not important.  The rainbow effect is due to diffraction of the sunlight by the photographer's hair. 

To see how this works, hold the tips of your thumb and forefinger very lightly together and look between your fingertips while holding them very close to your eye.  You have to look so closely that your fingers look fuzzy around the edges.  In fact, if you look between them at just the right angle (tangent to both fingertips while touching them together) the "fuzzy" part around their edges will appear to resolve itselve into little regions that float between the tips when you open them a tiny distance apart.  This fuzzy region and the little region visible between your fingertips are due to diffraction and interference between diffraction patterns as the light is diffracted around the tiny ridges of your fingerprints.  It's not just an optical illusion - the effect is visible in a properly illuminated shadow puppet, too.  Only on the scale of a shadow puppet those fuzzy regions will separate enough to resolve into colors. 

In the photograph, instead of fingerprint ridges, human hair is diffracting the light.  This gives a much more evenly distributed rainbow. 

(The photographer's jacket and hands are also refracting a little light, giving his/her shadow a little fuzz around the edges in the picture.  But the diffraction isn't sharp enough to separate the colors in the photograph.)

The diffraction isn't much.  Most of the light just goes straight through and mixes together as white light on the other side.  That's why the center appears brighter, BTW.  It is slightly more intensely illuminated, catching both refracted light from the photographers hair and incident sunlight, but you wouldn't notice it if the spectrum of the incident light weren't more evenly mixed and thus "whiter" than the sunlight.  (Notice how the top of the circular halo appears dimmer than the part around the shoulders?  That's the light that came through the photographer's bangs, which are apparently cut thinner than the poofy feathers on the side.)  The angle of illumination is slightly different inside the halo, too, which may allow a little extra light back to the camera, but not enough to notice without the shift in spectrum.

It occurs to me that it may even be possible to say what color the photographer's hair is.  Judging from the shadow, It looks like it's either curly and/or unkempt, with a lot of opacity.  The red light was most strongly refracted, which wouldn't be the case with a lot of transmission through the hair strands.  (Red is the outside ring in the rainbow, rather than the inside.) Based on that, I'm guessing brown to black, probably not red and definitely not blonde.

#674 Re: Martian Politics and Economy » A Dose of Hard, Cold, Economic Reality - International Cooperation is Essential » 2004-09-13 15:12:30

It's probably a combination of society being so complicated and demanding that people don't even consider children until they're over 30 and all the evils of feminism which causes nice guys to shy away from the mating market alltogether (or becoming unsuccesful in it) while still representing the best potential providers. In the age of housewives it used to be the male got a deal out of marriage and children, being able to count on support and relaxation at the home front, not anymore (although that doesn't exactly cover Japan where women are not yet deluded to the bone).

So, male chauvinism is the answer to female chauvinism?  :sleep:  Not very original.

Furtermore, when both parents are obliged to work in order to maintain a minimum standard of living, who's there to provide for the children?

You're correct.  IMHO, this is a symptom of the single greatest economic strain on the modern world.  We tried to trade a lifestyle whose cost was high in terms of labor for one whose cost was high in terms of money, and ended up increasing the cost in both.  Particularly here in the States.  Labor saving devices serve no purpose if every time one saves you an hour you immediately fit some other task into it.  The modern world must simplify its lifestyle or perish.

#675 Re: Not So Free Chat » NASA & Hurricane Frances » 2004-09-13 14:41:57

With a 10% chance that one is about to chase me up I-49 to Arkansas again, I can't think of a single strange thing about wanting hurricanes to go away!   :laugh:

(No, I have no further confidence in predictions that Ivan will strike the northern part of Florida.  I fully expect it to pass right through my bedroom.)   

As for the article about stopping hurricanes, my money is on the polyacrylide people.  Never underestimate the technological miracle of the disposable diaper.   :;):
