Children of the roaring 20s

Crooked Timber sent me to a 1957 article in the Atlantic monthly by Nora Johnson, who's book was later turned into an early Peter Sellers movie. A quick search didn't turn up a bio, but I assume she was born around 1935 -- a bit younger than my mother. She's 72 now, and likely living still.

I wonder what she makes of the old article.

The part that caught my eye was reflections on having parents who'd led wild and crazy lives. No, not in the 1960s. In the 1920s...
Sex and the College Girl

...Our parents kicked over so many traces that there are practically none left for us. That is not to say, of course, that all of our parents were behaving like the Fitzgeralds. Undoubtedly most of them weren't. But the twenties have come down to us as the Jazz Age, the era described by Time as having "one abiding faith—that something would happen in the next twenty minutes that would utterly change one's life," and this is what will go on the record. The people living more quietly didn't make themselves so eloquent. And this gay irresponsibility is our heritage. There is very little that is positive beneath it, and there is one clearly negative result—so many of our parents are divorced. This is something many of us have felt and want to avoid ourselves (though we have not been very successful). But if we blame our parents for their way of life, I suspect we envy them even more. They seemed so free of our worries, our self-doubts, and our search for what is usually called security—a dreary goal. I think that we bewilder our parents with our sensible ideas, which look, on the surface, like maturity...
Reads like Young Republicans of the Reagan eara.

SETI: find one of nine galactic civilizations

Damn Interesting has a very nice Drake Equation/SETI review today. Allan Bellow's even touches lightly on the Fermi Paradox, though he doesn't get into the various paradox resolutions.

The highlight of the article is an interactive Drake Equation calculator. Users start with various presets, including the 'rare earth' and the 'Drake 2004' options, then add their own biases. Two of the "terms" of the Drake Equation are now relatively accepted, below I show them and 3 variations on the rest: Drake 2004, rare earth, and me.
Common assumptions
New Milky Way stars per year = 6.00
Proportion of stars which have planets = 50.00%

Drake 2004
Average number of life-compatible satellites = 2.00
Percentage of planets where life does appear = 100.00%
Percentage where intelligent life evolves = 20.00%
Percentage of civilizations which send signals into space = 100.00%
Average years that civilizations will send signals = 10000.00
Average civilizations in our galaxy = 10,000

Rare Earth
Average number of life-compatible satellites = 0.000001
Percentage of planets where life does appear = 33.00%
Percentage where intelligent life evolves = 1.00%
Percentage of civilizations which send signals into space = 1.00%
Average years that civilizations will send signals = 10000.00
Average civilizations in our galaxy = 0

Me
Average number of life-compatible satellites = 0.10
Percentage of planets where life does appear = 87.50%
Percentage where intelligent life evolves = 20.00%
Percentage of civilizations which send signals into space = 90.00%
Average years that civilizations will send signals = 200.00
Average civilizations in our galaxy = 9.5
So Rare Earth ends up with zero civilizations, though I think this might be a bug. The first time I ran the calculations they had 1 civilization, presumably us.

Drake has 10,000 current civilizations that send signals for 10,000 years. This definitely runs into Fermi Paradox territory. If there are so many, and they endure for so long, then over galactic time scales at least one ought to have infested the stars.

I end up with 10 civilizations, of which we are 1. I get that by assuming an upper limit of 200 years of radio signals. We started radiating significantly around 1960, and if our civilization endures I don't think we'll be doing much wasteful radiating by 2160. I suspect we (or our inheritors) will be utterly incomprehensible, and perhaps uninterested in the merely physical universe.

This is a very small number of civilizations across a galaxy. Ssuch a low number makes it very unlikely that one of them will choose to aim a high intensity radio beam directly at us -- and that's all we can detect with today's technology.

We'd need to build a receptor the size of the solar system to pick up accidental signaling. I'm sure we could do that by 2160, but of course that takes us into the realm of the unimaginable.

So SETI won't find much.

Damn.

Update 12/31/09: I think we can rule out "rare earth". Also, another take on the Drake Equation.

McCain on torture: the least bad Republican

McCain's policies on lots of things, including his astounding ignorance of science, would put him well below any plausible Democrat for the presidency.

Even so, among the Republican candidates, he comes in first. For this if for nothing else:

INTEL DUMP - John McCain, good on you:

...ROMNEY: And as I just said, as a presidential candidate, I don't think it's wise for us to describe specifically which measures we would and would not use. And that is something which I would want to receive the counsel not only of Senator McCain, but of a lot of other people.
And there are people who, for many, many years get the information we need to make sure that we protect our country. And, by the way, I want to make sure these folks are kept at Guantanamo. I don't want the people that are carrying out attacks on this country to be brought into our jail system and be given legal representation in this country. I want to make sure that what happened ...
(Applause)
... to Khalid Sheikh Mohammed happens to other people who are terrorists. He was captured. He was the so-called mastermind of the 9/11 tragedy. And he turned to his captors and he said, "I'll see you in New York with my lawyers." I presume ACLU lawyers.
(Laughter)
Well, that's not what happened. He went to Guantanamo and he met G.I.s and CIA interrogators. And that's just exactly how it ought to be.
(Applause)...

"McCAIN: Then I am astonished that you would think such a — such a torture would be inflicted on anyone in our — who we are held captive and anyone could believe that that's not torture. It's in violation of the Geneva Convention. It's in violation of existing law... (Applause) And, governor, let me tell you, if we're going to get the high ground in this world and we're going to be the America that we have cherished and loved for more than 200 years. We're not going to torture people. We're not going to do what Pol Pot did. We're not going to do what's being done to Burmese monks as we speak. I suggest that you talk to retired military officers and active duty military officers like Colin Powell and others, and how in the world anybody could think that that kind of thing could be inflicted by Americans on people who are held in our custody is absolutely beyond me."...

[later]

McCAIN: Well, then you would have to advocate that we withdraw from the Geneva Conventions, which were for the treatment of people who were held prisoners, whether they be illegal combatants or regular prisoners of war. Because it's clear the definition of torture. It's in violation of laws we have passed. And again, I would hope that we would understand, my friends, that life is not "24" and Jack Bauer. Life is interrogation techniques which are humane and yet effective. And I just came back from visiting a prison in Iraq. The Army general there said that techniques under the Army Field Manual are working and working effectively, and he didn't think they need to do anything else. My friends, this is what America is all about. This is a defining issue and, clearly, we should be able, if we want to be commander in chief of the U.S. Armed Forces, to take a definite and positive position on, and that is, we will never allow torture to take place in the United States of America. (Applause)
Kudos to Intel Dump for including the Applause/Laughter annotations. In a just universe (pray it is not) those applauding Romney would get their afterlife orientation via Pol Pot.

How can McCain stomach his own people?

PS. The ID Comments included a link to Joe Klein's report on how Republican "undecided" voters responded to the debates. Chilling, but sadly predictable.

The spectrum wars: Chapter One

Google is ready to fight the 700MHz war.

Official Google Blog: Who's going to win the spectrum auction? Consumers.

... we announced today that we are applying to participate in the auction.

We already know that regardless of which bidders ultimately win the auction, consumers will be the real winners either way. This is because the eventual winner of a key portion of this spectrum will be required to give its customers the right to download any application they want on their mobile device, and the right to use any device they want on the network...

Regardless of how the auction unfolds, we think it's important to put our money where our principles are. Consumers deserve more choices and more competition than they have in the wireless world today. And at a time when so many Americans don't have access to the Internet, this auction provides an unprecedented opportunity to bring the riches of the Net to more people.

While we've written a lot on our blogs and spoken publicly about our plans for the auction, unfortunately you're not going to hear from us about this topic for awhile, and we want to explain why.
Monday, December 3, is the deadline for prospective bidders to apply with the FCC to participate in the auction. Though the auction itself won't start until January 24, 2008, Monday also marks the starting point for the FCC's anti-collusion rules, which prevent participants in the auction from discussing their bidding strategy with each other.

These rules are designed to keep the auction process fair, by keeping bidders from cooperating in anticompetitive ways so as to drive the auction prices in artificial directions. While these rules primarily affect private communications among prospective bidders, the FCC historically has included all forms of public communications in its interpretation of these rules.

All of this means that, as much as we would like to offer a step-by-step account of what's happening in the auction, the FCC's rules prevent us from doing so until the auction ends early next year. So here's a quick primer on how things will unfold:

  • December 3: By Monday, would-be applicants must file their applications to participate in the auction...
  • Mid-December: Once all the applications have been fully reviewed, the FCC will release a public list of eligible bidders in the auction. Each bidder must then make a monetary deposit no later than December 28, depending on which licenses they plan to bid on. The more spectrum blocks an applicant is deemed eligible to bid on, the greater the amount they must deposit.
  • January 24, 2008: The auction begins, with each bidder using an electronic bidding process. Since this auction is anonymous (a rule that we think makes the auction more competitive and therefore better for consumers), the FCC will not publicly identify which parties have made which bid until after the auction is over.
  • Bidding rounds: The auction bidding occurs in stages established by the FCC, with the likely number of rounds per day increasing as bidding activity decreases. The FCC announces results at the end of each round, including the highest bid at that point, the minimum acceptable bid for the following round, and the amounts of all bids placed during the round. The FCC does not disclose bidders' names, and bidders are not allowed to disclose publicly whether they are still in the running or not.
  • Auction end: The auction will end when there are no new bids and all the spectrum blocks have been sold (many experts believe this auction could last until March 2008). If the reserve price of any spectrum block is not met, the FCC will conduct a re-auction of that block. Following the end of the auction, the FCC announces which bidders have secured licenses to which pieces of spectrum and requires winning bidders to submit the balance of the payments for the licenses....

So Chapter One will likely run from now through March 2008.

Let the glorious battle begin! May the barbarians run rampant on the ruins of the Empire.

In Our Time: Symmetry, Moonshine, String Theory and E8

It's good to stretch one's mind on the way in to the office. It makes modeling relationships between arcane procedural descriptions and CPT codes seem pleasantly relaxing.

Today's stretch is courtesy of an In Our Time podcast [1] on symmetry. The professors do discuss Galois, but so far they've missed Emily Noether. Excellent anyway.

I'm not quite done, but I've learned about Galois, a bit of history, and, for the first time, I have a vague understanding of what Group Theory is about and it's relationship to geometry and topology. Not bad for free.

Towards the end of the podcast they talk about mysterious relationships between one "monstrous" element in an "atlas" of "Groups", where a Group is a collection of mathematical objects with shared symmetric transformations. One of them, the "monster", is described as having a mysterious relationship with mathematical physics.

Cue Wikipedia:
Monstrous moonshine - Wikipedia, the free encyclopedia

Specifically, Conway and Norton, following an initial observation by John McKay, found that the Fourier expansion of j(τ) ... could be expressed in terms of linear combinations of the dimensions of the irreducible representations of M ...

... lying behind monstrous moonshine is a certain string theory having the Monster group as symmetries; the conjectures made by Conway and Norton were proven by Richard Ewen Borcherds in 1992 using the no-ghost theorem from string theory and the theory of vertex operator algebras and generalized Kac-Moody superalgebras.

... Igor Frenkel, James Lepowsky and Arne Meurman explicitly constructed this representation using vertex operators in conformal field theory describing bosonic string theory compactified on a 24-dimensional torus generated by the Leech lattice and orbifolded by a reflection. The resulting module is called the Monster module...

Well, ok, so I didn't exactly follow all of that. Impressive at a cocktail party no doubt, but we don't do that sort of thing.

All quite exciting in a geeky sort of way, except bosonic string theory seems to have been a bit of a dead end. Again, from Wikipedia (emphases mine, I thought this was a lovely explanation btw_:
Bosonic String theory is the original version of string theory, developed in the late 1960s. Although it has many attractive features, it has a pair of features that render it unattractive as a physical model. Firstly it predicts only the existence of bosons whereas we know many physical particles are fermions. Secondly, it predicts the existence of a particle whose mass is imaginary implying that it travels faster than light. The existence of such a particle, commonly known as a tachyon, would conflict with much of what we know about physics, and such particles have never been observed.

Another feature of bosonic string theory is that in general the theory displays inconsistencies due to the conformal anomaly. In a spacetime of 26 dimensions, however, with 25 dimensions of space and one of time, the inconsistencies cancel. Another way to look at this is that in general bosonic string theory predicts unphysical particle states called 'ghosts'. In 26 dimensions the no-ghost theorem predicts that these ghost states have no interaction whatsoever with any other states and hence that they can be ignored leaving a consistent theory. So bosonic string theory predicts a 26 dimensional spacetime. This high dimensionality isn't a problem for bosonic string theory because it can be formulated in such a way that along the 22 excess dimensions, spacetime is folded up to form a small torus. This would leave only the familiar four dimensions of spacetime visible.

In the early 1970s, supersymmetry was discovered in the context of string theory, and a new version of string theory called superstring theory (supersymmetric string theory) became the real focus. Nevertheless, bosonic string theory remains a very useful "toy model" to understand many general features of perturbative string theory, and string theory textbooks usually start with the bosonic string...
So why does Time always get only one dimension? Space seems awfully greedy.

So the monster/physics connection didn't quite hold up, but one supposes Supersymmetry might have some familial connection to the Monster.

Or perhaps there's another step up?
... E8 is the symmetries of a geometric object that is 57-dimensional. E8 itself is 248-dimensional...

...Hermann Nicolai, Director of the Albert Einstein Institute in Potsdam, Germany. "While mathematicians have known for a long time about the beauty and the uniqueness of E8, we physicists have come to appreciate its exceptional role only more recently - yet, in our attempts to unify gravity with the other fundamental forces into a consistent theory of quantum gravity, we now encounter it at almost every corner."
Or a step down?
... Since 1997, physicists have proposed countless variations on Maldacena's theme, all of which interpret a string as a swarm of particles living in a small number of dimensions. Perhaps the easiest case to visualize is when that number is two. In such a scenario, anything that takes place in your many-dimensional, stringy universe has a sort of shadow representation in terms of particles moving on that universe's 'sphere at infinity.' This esoteric-sounding concept is actually similar to the familiar celestial sphere of the night sky as seen from Earth: It's the two-dimensional surface spanning all possible directions one can point to infinitely far in space..
I probably need to stop now. Work beckons, and my furhter inquires on relationship between E8 and the Monster Group started running into "alternative physics" posts. I have enough trouble with "conventional" physics, thanks.

Ok, one last comment. In the nice, sane, quiet world of the humble Higgs (God) particle CV tells us:
... if you impose upon our relativistic, complex, quantum-mechanical wavefunctions the requirement that they be invariant under these U(1) transformations, then you get electromagnetism. Conservation of electric charge. A massless photon. QED - quantum electrodynamics, in all its 12-digit precision glory. Electromagnetism is a simple consequence of the U(1) symmetry of any wavefunction....
It's all relative (sorry). QED seems perfectly pedestrian now.

[1] From a prior post:

Melvyn Bragg's BBC show, In Our Time, has begun a new season. I'm a fan.

The bad news is that the BBC is sticking with its execrable latest-episode-only download policy. So if you want to listen to the superb Opium War episode on your MP3 player you need to either use Audio Hijack Pro to capture the RealAudio stream or (if you know me) ask me for a DVD with the entire series [1]. Incidentally, this is a good time to write a quick email to set IOT free.

The good news is there's a new page that makes it easy to subscribe to a feed. I used to subscribe via iTunes, but if I went a week without using iTunes I missed the show. Now I subscribe via iTunes and Bloglines; I use Bloglines at least daily so it's easy for me to save the MP3 and email it to myself.

The Economist's print edition has a full Feed

So how are they going to make money?

There's now a full feed for The Economist print edition. It's somewhat useful for reading (esp. on the Kindle methinks), but it doesn't provide any orientation cues. So no "Africa", "Lexington", etc. It does let you know a new version has been released and it's easy to click to the web view.

I ended my Economist subscription about two years ago when the quality went down the tubes. It's still pretty crummy, but this feed will get me scanning the articles at least. Their science and Africa coverage is still quite good.

In January the WSJ is supposed to go free as well.

I will need to boost my scanning speed.

HealthcareITJobs - from Mr HISTalk

This is a bit different from my usual posts.

I work in healthcare IT. I've done it for over 10 years, mostly in a large corporation. The last bit is mind boggling.

Anyway, in our industry we read HISTtalk, the anonymous blog of a healthcare CIO. At its best it's a rich source of industry gossip, though in recent months it's been a bit dull. The contradictions of writing interesting things about companies that are also sponsors may be taking its toll.

Today's issue tells Mr. HISTalk is getting behind a job board focusing on Healthcare IT, named, remarkably, HealthcareITJobs. If you're interested in this industry it is likely worth a look.

BTW, the best Healthcare CIO blog belongs to Harvard's John Halamka's, aka the "geekdoctor". It's amazing, I write about it on our corporate blogs pretty regularly.

How Venus got its CO2 atmosphere

Praise goes to Kenneth Chang, for writing the first article on recent Venus discoveries that makes any sense.

We know why Venus is hot -- it's the CO2 atmosphere. The new discoveries are about how Venus went from an atmosphere like ours to a very dense atmosphere that's almost all CO2 ...
New Findings Underscore an Earth-Venus Kinship - New York Times:

... Subsequent visits by spacecraft confirmed that the surface temperatures exceed 800 degrees Fahrenheit, hot enough to melt tin and lead...

... Scientists imagine that Venus formed with much liquid water, just like Earth, but that because it is closer to the Sun, with sunlight twice as intense as on Earth, the water began to evaporate. Water vapor, also a greenhouse gas, trapped heat.

“That heats up the surface and leads to more evaporation,” said David Grinspoon of the Denver Museum of Nature & Science. “It’s a powerful feedback.”

The evaporation accelerated until all the liquid water had turned into a thick atmosphere of water vapor. As the water molecules floated in the air, scientists hypothesize, ultraviolet rays from the Sun broke them apart into hydrogen and oxygen atoms. Chemical reactions with minerals in the rocks transformed the oxygen into carbon dioxide. The hydrogen, the lightest of atoms, escaped into outer space...
So the oceans of Venus, and a chunk of its surfce, turned into an ultra-dense atmosphere of CO2. That's a satisfying story. It will likely help us understand what the habitable zone of star is.

Anyone have a few bazillion tons of hydrogen lying about?

Selfishness and its justifications

I'm echoing DeLong here, save I think the thesis is at least as true of America libertarians as of American conservatives.
D-squared Digest -- FOR bigger pies and shorter hours and AGAINST more or less everything else:

...As I've posted earlier, the single most sensible thing said in political philosophy in the twentieth century was JK Galbraith's aphorism that the quest of conservative thought throughout the ages has been 'the search for a higher moral justification for selfishness'.

Some rightwingers are not hypocrites because they admit that their basic moral principle is 'what I have, I keep'.

Some rightwingers are hypocrites because they pretend that 'what I have, I keep' is always and everywhere the best way to express a general unparticularised love for all sentient things.

Then there are the tricky cases where the rightwingers happen to be on the right side because we haven't yet discovered a better form of social organisation than private property for solving several important classes of optimisation problem...
Neo-calvinism is the American fusion of 'selfishness as virtue' with 'wealth as a sign of God's blessings'.

China's hundred billion reasons to dislike the US

Maybe this is why China blocked US ships from entering Hong Kong ...
Dyer- The US Dollar: The Long Farewell

...China, which was sitting on about a trillion US dollars, simply lost several hundred billion as the currency's value fell....
So, does this mean China has just paid a large chunk of the costs of America's adventures in Iraq?

That might engender a certain amount of unhappiness.

Yes, Google does know where I am

Today I searched on "arrowhead resort".

After about 2-3 hits Google inserted something new. A geographically constrained suggestion:
arrowhead resort - Google Search: "See results for: arrowhead resort minnesota"
Ahh. Yes, I'd read Google was going to be adding location to their search results, using both traditional IP location and more exotic methods.

It's a bit spooky, but good.

Privacy? I fought that battle in the early 90s. Nobody was interested. It's much too late now.

History of the First Peoples - Charles Mann's 1491

Charles Mann wrote a 2002 article in the Atlantic about the human history of the Americas prior to the European invasion. This article became a 2004 NYT essay and then a well regarded 2006 book.

Most recently this letter to Brad DeLong, published on Brad's blog, is a great advert for the book (emphases mine) ...
Grasping Reality with Both Hands: Brad DeLong's Semi-Daily Journal

... Pennington correctly observes that I "barely mentioned the horrible [e]ffects of the wars that went on between the whites and indians." This is because I was writing about demography and demographically they didn't amount to much. By the 18th century, disease had already wiped out 75-95% of the native population of the Americas. Indian warfare, awful as it often was, simply piled on another few percentage points to the mortality count.

... As the historian Alfred Crosby has repeatedly observed, societies tend to measure "progress" in terms of things that they are good at. Europeans were good at making metal tools and devices, so we tend to look for them -- Indians didn't have steel axes and geared machines, so they must be inferior. But many Indian societies were extremely deft about agriculture. Looking at a Europe afflicted by recurrent famine, one can imagine them viewing these societies as so undeveloped that they were unable to feed themselves. It's hard to say which view is correct.

...many European innovations were directly related to the existence of domestic animals. At the time of its construction, the Roman highway system had no direct equivalent in the Americas. Paved roads are obviously a sign of technological development, because you need them for large-scale transportation, right? But it would have been nuts for Indians to have built such roads, because they didn't have wheeled vehicles. And they didn't have wheeled vehicles (except as toys) because they didn't have horses, and they evidently calculated that the small gains in efficiency for human-powered vehicles was not worth the large costs in labor and materials to build highways, especially when rivers were an attractive alternative. (Compared to Europe, much of the Americas is river-rich.) So does this mean that Native America was less developed?

Lauren Tombari asks, "Wouldn´t there be some evidence of the many towns Desoto saw? Would there be ~100 million graves from the 95% death rate?" She will be happy to learn there is lots of evidence of the many towns seen by DeSoto. Although it is inexplicably absent from US history textbooks, there were literally thousands of mound cities and towns in the US Southeast and the Mississippi valley. Many have been destroyed, but my book, 1491, has a map of some of the main sites that remain. About the graves: the answer is no. In epidemics, people generally aren't buried, but left to die where they fall. The vast majority of those skeletons simply vanish. An example of this is the slaughter of the buffalo. We know from abundant historical records that less than 150 years ago hunters killed millions of bison in the Great Plains. Yet if you drive around there now, you don't see heaps of bones. The same, alas, happened to Indians. Of course it didn't happen to every Indian -- and there are many, many known Indian graveyards, so many that the federal government has passed special legislation to protect them.

... In this country, the French, Spanish, Dutch and English made more than 20 attempts to found colonies before the Pilgrims. All but one of them failed. The exception was Jamestown, in which almost 5 out of 6 colonists sent in the first 15 years died -- something that most people would regard as a failure. (St. Augustine, in Florida, was founded before Plimoth, but it was abandoned for years before being resettled, so I would count it as a failure, too.) Then comes the epidemic in New England, and suddenly, beginning with the Pilgrims, almost every English colony survives and thrives.
The thesis, in short, is that the pre-euro population of the Americas was tens of millions of people, perhaps 100 million. A larger population than the Europe of that time.

A possible counter-argument would be to ask why then did Amerindians not have their equivalent of the Euro's embedded bio-weapons? A population of that size should be able to support some very nasty viruses.

The Atlantic article argues that humans disseminated throughout the Americans long before 12,000 BCE, however I think recent gene data supports the 12,000 BCE date for all living descendants of the first people. Animal extinction and canine genomic data may also support the 12,000 BCE date. If 12,000 BCE is in fact the date for entrance to the Americas, that might also argue against such a vast population.

See also: Squanto's story, European rat plagues kill American rats, Mann's 2004 NYT essay, European dog diseases kill American dogs.

Regardless of the original population the euro "conquest" (inheritance, almost) of the Americas is an abject lesson in the awesome power of biological WMDs.

Romney and Mormon theology

Four years ago I wrote about John Krakauer's book on Mormon fundamentalism. I've also visited the Mormon temple in Salt Lake City -- something no tourist should miss.

Between those two primary sources, and a few other readings, I came away thinking that Mormonism is no odder than any other religion, but that it suffers the great disadvantage of being born in the modern world. The Mormon church has only become socially respectable within the past 30 years (really end polygamy, deemphasize the sin of being pigmented), and we know, unfortunately, far more about Smith than Buddha or Christ.

Here's how the Enclyclopedia Brittanica describes Mormon theology:
...The Book of Mormon recounts the history of a family of Israelites that migrated to America centuries before Jesus Christ and were taught by prophets similar to those in the Old Testament. The religion Smith founded originated amid the great fervour of competing Christian revivalist movements in early 19th-century America but departed from them in its proclamation of a new dispensation. Through Smith, God had restored the “true church”—i.e., the primitive Christian church—and had reasserted the true faith from which the various Christian churches had strayed..
The Britannica article omits some interesting details. Mormons believe the ancient peoples of America fought a cataclysmic "high tech" (compared to pre-civil war America) battle. The story is no more bizarre than "Noah's Ark", but it's a different story than Christians are accustomed to hearing.

This is why I've been amazed that Romney has been able to run for president within the GOP. Socially and culturally he has a lot in common with Christian fundamentalists, but so do Islamic fundamentalists. Mormonism is no closer to Christianity than is Islam. How does this
ever play within the GOP?

This must annoy people like Christopher Hitchens who struggles in Slate to find a secular justification for asking Romney about the Mormon church ...
Mitt Romney needs to answer questions about his Mormon faith. - By Christopher Hitchens - Slate Magazine

...It ought to be borne in mind that Romney is not a mere rank-and-file Mormon. His family is, and has been for generations, part of the dynastic leadership of the mad cult invented by the convicted fraud Joseph Smith. It is not just legitimate that he be asked about the beliefs that he has not just held, but has caused to be spread and caused to be inculcated into children. It is essential. Here is the most salient reason: Until 1978, the so-called Church of Jesus Christ of Latter-day Saints was an officially racist organization. Mitt Romney was an adult in 1978. We need to know how he justified this to himself, and we need to hear his self-criticism, if he should chance to have one...
Hmph. The argument feels week.

It would be interesting to know whether Romney is a racist or not, but we should be able to find that out from the Boston media who knew him as governor of Massachusetts. Otherwise Romney's religion and theology are mostly curiosities for secular humanists, agnostics, and atheists.

For Christian, particularly fundamentalists and evangelicals, the questions are far more important. I'm a bit surprised, but mostly amused, that nobody asks on their behalf.

The cinema beneath the Seine

Today we all feel proud of the French.
Undercover restorers fix Paris landmark's clock | Special reports | Guardian Unlimited:

...Klausmann and his crew are connaisseurs of the Parisian underworld. Since the 1990s they have restored crypts, staged readings and plays in monuments at night, and organised rock concerts in quarries. The network was unknown to the authorities until 2004, when the police discovered an underground cinema, complete with bar and restaurant, under the Seine. They have tried to track them down ever since....
Emily thinks they've been reading Neil Gaiman.

So is the spelling "connaisseurs" a clever word play?

The American cellular empire has fallen, let the wars begin

This is what Europeans have had forever:
Verizon Wireless Says ‘Bring Your Own’ Device - Bits - Technology - New York Times Blog:

... Verizon Wireless has stunned the wireless world by announcing that by sometime next year it will open its network to “any apps, any device.” There is a lot of fine print, but the essence appears to be that Verizon will offer two flavors of service: its traditional bundle, which typically includes a subsidy for phone purchase and various other features, and “bring your own” device service, which will be open to any device that meets “minimum technical standards.”...
The excellent NYT blog post connects this move to the big bandwidth brawl (BBB) over the 700 MHz US spectrum. On a related front T-Mobile announced a month or so ago that their future phones will support VOIP over Wifi.
