Trying to sort out truth from speculation at Fukushima

The only thing that is certain about the Fukushima situation right now is that both the operating company (Tokyo Electric Power Co. aka TEPCO) and the Japanese government have been ridiculously slow to provide information. They may or may not be actively concealing what they know, but they’re taking far too long to share what they do know with the rest of the world.

Inline update: New Scientist has a timeline of Japanese nuclear cover-ups and accidents. [end update]

wormme is a radiological control technician, so he’s very well informed about the overall picture — in a way non-specialists are not — and he’s had an epiphany about Fukushima:

See the light bulb above my head? Lesson Learned!

My first post on Fukushima is still the most widely read. Alas. I’m a radiological control technician who wasn’t paranoid about a radiological situation. Never good. Never acceptable. So I’ve been “hotwashing” myself ever since.

Where did I go wrong? What was the first cause, the primary mistake? I had to know in order to answer the most important question of all:

How do I never make that mistake again?

I turned a nifty phrase in “incalculable danger”, got generous links . . . then steam began venting and cores melting and hydrogen exploding and fuel pools leaking and spent fuel smoldering, all at once, with my brain sprinting like a hamster on a wheel and making about as much progress.

How did Fukushima have several quiet days after the event and only then have the Hellmouth open?

No lesson learned.

Then a couple of days ago we learned the site went six days without electricity. That monstrous tsunami took out the electrical backups, the backup-backups, and the backup-backup-backups in one fell swoop.

And I thought, ”well, that explains most everything”.

But still, no lesson learned.

It’s only now, right now, the realization: I wrote the post assuming that they had electrical power.

Not even an assumption, really. It wasn’t even a consideration. Of course they had power. They couldn’t possibly not have power.

But they did not have power.

Lesson Learned: the Japanese are different from Americans.

He also has interesting and highly informative posts (earlier than the one quoted above, so perhaps to be read with that in mind) on radiation poisoning, stuff that can cause a meltdown, some crappy radiological terminology, characteristics of radiation(s) and shielding(s), why the spent fuel is a bigger problem than the reactors, nuclear triage, time, distance, and shielding, spent fuel pools, first notes on the “Event Summary” file, and how NOT to wear a respirator.

West coast earthquake zones

Filed under: Cancon, Environment, Pacific, USA — Tags: , , , , , — Nicholas @ 09:44

According to an article in The Economist, the well-known San Andreas fault in California is not the most likely to cause an earthquake of the magnitude of last week’s quake in Japan. The most likely source is the Cascadia subduction zone:

wikimedia.org - Cascadia subduction zone The most likely megaquake on the West Coast would be much further north — in fact, 50 miles off the coast between Cape Mendocino in northern California and Vancouver Island in southern British Columbia. This 680-mile strip of seabed is home to the Cascadia subduction zone, where oceanic crust known as the Juan de Fuca plate is forced under the ancient North American plate that forms the continent. For much of its length, the two sides of this huge subduction zone are locked together, accumulating stresses that are capable of triggering megaquakes in excess of magnitude 9.0 when they eventually slip. As such, Cascadia is more than a match for anything off the coast of Japan.

What makes Cascadia such a monster is not just its length, but also the shallowness of the angle with which the encroaching tectonic plate dives under the continental mass. The descending plate has to travel 40 miles down the incline before it softens enough from the Earth’s internal heat to slide without accumulating further frictional stresses. Could the fault unzip from end to end and trigger a megaquake — along with the mother of all tsunamis? You bet. By one account, it has done so at least seven times over the past 3,500 years. Another study suggests there have been around 20 such events over the past 10,000 years. Whatever, the “return time” would seem to be within 200 to 600 years.

And the last time Cascadia let go? Just 311 years ago.

“Obesity crusaders” use “inherently flawed instruments, such as BMI and apple-body shapes, to misinform the public”

Filed under: Government, Health, Media — Tags: , , , — Nicholas @ 12:50

Patrick Basham and John Luik address the manifest failings of the public health crusade against obesity:

Since the anti-obesity campaign is allegedly motivated by scientific findings, it would seem reasonable and prudent to make doubly sure that those claims are factual and trustworthy. Yet, we continue to find that the case against obesity is significantly flawed. Not only are the claims of an obesity epidemic often wildly exaggerated, but the science linking weight to unfavourable mortality outcomes is also frequently nonexistent or distorted.

[. . .]

As Danesh suggests, other researchers have suggested concentrating on a measurement of the waist alone, while many cling to BMI, which calculates obesity based upon a weight-to-height ratio. Because of its easy applicability, BMI is universally used in officially defining obesity, despite its manifest shortcomings. The BMI is wholly arbitrary and has no scientifically valid connection with mortality.

“Obesity crusaders” are what we call the individuals who manufactured the obesity-epidemic story in the first place and continue, through application of inherently flawed instruments, such as BMI and apple-body shapes, to misinform the public. They are a relatively small group of public-health officials in the US, the UK, the EU, and the World Health Organisation, assorted academics (very many with close ties to the weight-loss and pharmaceutical industry), the International Obesity Task Force, and a collection of so-called public-interest science groups.

How are these obesity crusaders reacting to the unambiguously good news published in The Lancet? Surely, they rejoice at the fact there is one less thing for a health-conscious population to fret over? No, they are not in celebratory mood. Quite the contrary. The obesity crusaders did not waste any time on the New Good News; after all, the Old-Time Religion continues to serve them so well.

It gets worse for the “fat=early death” meme:

There is little credible scientific evidence that supports the claims that being overweight or obese leads to an early death. For example, Katherine Flegal of the Centers for Disease Control and Prevention found that in the US population there were more premature deaths among those who are normal weight than those who are overweight. Indeed, in this study, Americans who were overweight were those most likely to live the longest.

In the American Journal of Public Health, Jerome Gronniger found that men in the “normal” weight category exhibited a mortality rate as high as that of men in the moderately obese category; men in the “overweight” category clearly had the lowest mortality risk.

DC residents get stiffed on their solar power subsidies

David Nakamura reports on some Washington, DC folks who are feeling ripped off by their local government over solar panel reimbursements that were promised but never delivered:

It isn’t easy going green, and it may also prove costly.

Dozens of District residents who installed solar panels on their homes under a government grant program promoting renewable energy have been told they will not be reimbursed thousands of dollars as promised because the funds were diverted to help close a citywide budget gap.

In all, the city has reneged on a commitment of about $700,000 to 51 residents, according to the D.C. Department of the Environment. The agency has pledged to try to find money in next year’s budget, its director, Christophe Tulou, said.

“It just doesn’t seem fair to go through a process with them and have them make investments in solar panels under the assumption they would be reimbursed,” Tulou acknowledged. “It’s really sad we are having these economic woes when we are.”

Update on the Fukushima situation

Filed under: Bureaucracy, Environment, Japan, Technology — Tags: , , , — Nicholas @ 09:04

Colby Cosh complained yesterday about the low quality of information being provided by the Tokyo Electric Power Company (TEPCO), and that has not really improved since yesterday. At The Register, Lewis Page updates the situation as best he can:

The story of the three quake- and tsunami-hit reactors at Japan’s Fukushima plant continues, with indications that one of the three worst-hit reactors has sustained further damage. A fire also broke out at another reactor, shut down at the time of the quake and not previously thought to be a problem, but this has now been put out. None of this suggests that the reactors’ crucial containment vessels could be breached, however.

World Nuclear News reported in the early hours (UK time) that a “loud noise” had been heard at the site of the No 2 reactor at Fukushima and pressure readings had fallen in the doughnut-shaped “suppression chamber” situated beneath the core. The suppression chamber holds a large quantity of water and steam from the core, released into it to be condensed, so reducing pressure in the core without the need to vent to atmosphere in some situations: though reactors 1, 2 and 3 have all been repeatedly vented to atmosphere since the quake nevertheless.

Following the apparent release from inside the suppression chamber, radiation levels at the site briefly rose to 8217 microsieverts per hour — such that an unprotected person outside would receive several years’ normal background radiation dose in a single hour. Radiation then dropped to less than 2,500 microsievert/hr. (UPDATED TO ADD: The IAEA reports that as of 6am UK time this had fallen to 600 microsievert/hr). WNN reports that a statement from TEPCO, the plant operators, stated that there had been “no significant change” to the status of the vital containment vessel surrounding the reactor core.

Drinking is good for you, but we still don’t know why it’s good for you

Filed under: Health, Science, Wine — Tags: , , — Nicholas @ 14:17

Moderate drinking (defined as 2-3 drinks per day) is proven to be healthy for most people, but the jury is still out on why it’s good for you:

Scientists say that more research needs to be done to understand why alcohol may be beneficial in small doses. Most commonly, evidence shows that alcohol is associated with increased cardiovascular health. Researchers at the University of Calgary recently analyzed data on alcohol consumption and heart disease and determined that those who drink one to two glasses of alcohol per day are up to 25% less likely to develop heart disease.

The team, lead by Dr. William Ghali, found that moderate drinking led to higher levels of “good” cholesterol and a decrease of a chemical responsible for blood clotting. It doesn’t matter if the booze is from Chateau Mouton-Rothschild or Labatt’s; “it does appear to be alcohol itself that is causing these favourable outcomes,” Dr. Ghali, a professor of medicine at the university, said.

Earthquake, tsunami, and worse

Filed under: Environment, Japan, Pacific — Tags: , , , , — Nicholas @ 12:04

The earthquake by itself was one of the biggest ever recorded, and then the tsunami compounded the quake damage and will make relief and rescue efforts that much harder. Kevin Voigt has more:

The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis.

“At this point, we know that one GPS station moved (8 feet), and we have seen a map from GSI (Geospatial Information Authority) in Japan showing the pattern of shift over a large area is consistent with about that much shift of the land mass,” said Kenneth Hudnut, a geophysicist with the U.S. Geological Survey (USGS).

Reports from the National Institute of Geophysics and Volcanology in Italy estimated the 8.9-magnitude quake shifted the planet on its axis by nearly 4 inches (10 centimeters).

The temblor, which struck Friday afternoon near the east coast of Japan, killed hundreds of people, caused the formation of 30-foot walls of water that swept across rice fields, engulfed entire towns, dragged houses onto highways, and tossed cars and boats like toys. Some waves reached six miles (10 kilometers) inland in Miyagi Prefecture on Japan’s east coast.

Another major concern is the ongoing struggle to regain control of one of the reactors at the Fukushima Daiichi nuclear power plant:

An explosion at an earthquake-struck nuclear plant was not caused by damage to the nuclear reactor but by a pumping system that failed as crews tried to bring the reactor’s temperature down, Chief Cabinet Secretary Yukio Edano said Saturday.

Workers at the Fukushima Daiichi plant have begun flooding the reactor containment structure with sea water to bring the reactor’s temperature down to safe levels, he said. The effort is expected to take two days.

Radiation levels have fallen since the explosion and there is no immediate danger, Edano said. But authorities were nevertheless expanding the evacuation to include a radius of 20 kilometers (about 12.5 miles) around the plant. The evacuation previously reached out to 10 kilometers.

Massive earthquake in northern Japan

Filed under: Environment, Japan, Pacific — Tags: — Nicholas @ 08:27

The largest earthquake since records began hit northern Japan at about quarter to three local time, just as the rush hour was about to start. BBC News has ongoing live coverage.

The tremor, measured at 8.9 by the US Geological Survey, hit at 1446 local time (0546 GMT) at a depth of about 24km.

A tsunami warning was extended across the Pacific to North and South America.

The Red Cross in Geneva warned that the tsunami waves could be higher than some Pacific islands, Reuters news agency said.

Coastal areas in the Philippines, Hawaii and other Pacific islands were evacuated ahead of the tsunami’s expected arrival.

New Zealand later downgraded its alert to a marine threat, meaning strong and unusual currents were expected.

“An opportunity to stop English libel law chilling free speech around the world”

Filed under: Britain, Law, Liberty, Science — Tags: , , — Nicholas @ 12:43

Simon Singh at the Guardian‘s “Comment is Free” site explains just how much the chilling effect of English libel law can obstruct free speech:

. . . it is important to remember that for every case of a scientist or journal who dares to face the ordeal of a libel trial, there are dozens of (or probably hundreds of) others who immediately apologise and retract after a libel threat, or who self-censor in order avoid any risk of libel, which is the so-called chilling effect of libel.

For example, I gave an interview to an Australian medical correspondent at the Melbourne Age about the lack of evidence surrounding homeopathy, but he was unable to quote me in detail because his in-house lawyer was frightened of being sued for libel in London. The only reason this came to light was because the journalist in question wrote a blog describing how tough it was to be a health journalist in Australia when the vulture of English libel law was always circling above.

More worryingly, I recently received an email from an American researcher (whose name I cannot mention) who had worked with a librarian (whose name I cannot mention) to write a paper on the subject of impact factors, the scoring system often used by librarians and others to assess the quality of a research journal. The anonymous researchers cited one journal (whose name I cannot mention) which may be using certain techniques to boost its own impact factor. Impact factors are an important issue, so the paper was sent to a respected British journal (which I shall not name in order to avoid embarrassment) with an international readership. The journal replied: “We regret that we are unable to publish after all because unfortunately it has potential legal implications under UK libel law.”

The anonymous researchers then sent the paper to an American journal (which I shall not name), which also had an international readership and which did agree to publish the paper. Initially, there seemed to be no problem, because the in-house lawyer agreed that the paper did not breach US libel law. However, the lawyer went on to demand that edits were necessary or there would be a serious risk of being sued in London according to English libel law.

The British government is to introduce a new bill to (one hopes) address some of these concerns soon. Let’s hope that they’re paying attention.

“Secret space warplane” to launch on secret mission with secret payload

Filed under: Military, Space, USA — Tags: , — Nicholas @ 10:10

Anything that gets Iran’s leadership all worked up into a panic can’t be all bad:

The US Air Force is set to launch its second X-37B miniature unmanned spaceplane — the type famously dubbed a “secret space warplane” by the Iranian government — on Friday.

[. . .]

Once in orbit the X-37B deploys a solar panel array, unlike its bigger cousin the Space Shuttle which uses fuel cells for electrical power. Thus the little robot spaceplane can remain in orbit for much longer periods unsupported before re-entering the atmosphere to make a runway landing. The previous OTV-1 mission, carrying a payload which remains secret, lasted 224 days and ended with a successful landing at the Vandenberg military space base in California.

As yet the USAF has not revealed the planned duration of the OTV-2 mission launching tomorrow, and again details of the payload are not being revealed.

There has been extensive speculation among space watchers regarding just why the USA needs a small robotic spaceplane. For most purposes a more normal spacecraft, unburdened by heat shields for re-entry, would be more economical. Even supposing a need to return to Earth, there would seem to be no need for the X-37B’s Shuttle-style delta wings, which add weight unnecessarily — a capsule design could be used, or a lifting body if runway landing was regarded as essential.

“Where have the good men gone?” and the women who chase after jerks

Filed under: Economics, Education, Health — Tags: , , , — Nicholas @ 07:53

As I predicted a few weeks back, this topic appears to be a growing concern (at least in certain key urban media markets): “why are men so juvenile and why won’t they settle down?”

First up is Mark Regnerus:

We keep hearing that young men are failing to adapt to contemporary life. Their financial prospects are impaired — earnings for 25- to 34-year-old men have fallen by 20 percent since 1971. Their college enrollment numbers trail women’s: Only 43 percent of American undergraduates today are men. Last year, women made up the majority of the work force for the first time. And yet there is one area in which men are very much in charge: premarital heterosexual relationships.

First, it’s not at all a bad thing that women are catching up and in some cases surpassing their male classmates. Along with the good, however, are some wrenching changes to the society in which this change is taking place — especially to sexual relationships:

When attractive women will still bed you, life for young men, even those who are floundering, just isn’t so bad. This isn’t to say that all men direct the course of their relationships. Plenty don’t. But what many young men wish for — access to sex without too many complications or commitments — carries the day. If women were more fully in charge of how their relationships transpired, we’d be seeing, on average, more impressive wooing efforts, longer relationships, fewer premarital sexual partners, shorter cohabitations, and more marrying going on. Instead, according to the National Longitudinal Study of Adolescent Health (which collects data well into adulthood), none of these things is occurring. Not one. The terms of contemporary sexual relationships favor men and what they want in relationships, not just despite the fact that what they have to offer has diminished, but in part because of it. And it’s all thanks to supply and demand.

It’s not just raw numbers: the sexual balance hasn’t been significantly changed just because of the shift in the proportion of men and women going on to higher education. What has been impacted is something that doesn’t yield readily to slogans or seminars: women have strong preferences for men of higher status than themselves. This isn’t a social preference that can be talked around: it has much more to do with biology.

Women prefer to “date up” or “marry up”, and the pool of males that fit that criteria is getting smaller (fewer men are going on to university). This forces women to compete for the limited number of alpha males: instead of being pursued by eager men, (some) men are now being pursued by many women. Resulting, at least for that group of men, in copious supplies of women willing to exchange sex for attention.

Kay S. Hymowitz sees the extended adolescence for men as a new stage of life, pre-adulthood:

So where did these pre-adults come from? You might assume that their appearance is a result of spoiled 24-year-olds trying to prolong the campus drinking and hook-up scene while exploiting the largesse of mom and dad. But the causes run deeper than that. Beginning in the 1980s, the economic advantage of higher education — the “college premium” — began to increase dramatically. Between 1960 and 2000, the percentage of younger adults enrolled in college or graduate school more than doubled. In the “knowledge economy,” good jobs go to those with degrees. And degrees take years.

[. . .]

In his disregard for domestic life, the playboy was prologue for today’s pre-adult male. Unlike the playboy with his jazz and art-filled pad, however, our boy rebel is a creature of the animal house. In the 1990s, Maxim, the rude, lewd and hugely popular “lad” magazine arrived from England. Its philosophy and tone were so juvenile, so entirely undomesticated, that it made Playboy look like Camus.

At the same time, young men were tuning in to cable channels like Comedy Central, the Cartoon Network and Spike, whose shows reflected the adolescent male preferences of its targeted male audiences. They watched movies with overgrown boy actors like Steve Carell, Luke and Owen Wilson, Jim Carrey, Adam Sandler, Will Farrell and Seth Rogen, cheering their awesome car crashes, fart jokes, breast and crotch shots, beer pong competitions and other frat-boy pranks. Americans had always struck foreigners as youthful, even childlike, in their energy and optimism. But this was too much.

Given all of that, is it any surprise that fewer men are willing to exchange their pre-adult lifestyle with all its juvenile attraction combined with the adult trappings (cars, booze, drugs, etc.) for the “real” adult lifestyle?

Single men have never been civilization’s most responsible actors; they continue to be more troubled and less successful than men who deliberately choose to become husbands and fathers. So we can be disgusted if some of them continue to live in rooms decorated with “Star Wars” posters and crushed beer cans and to treat women like disposable estrogen toys, but we shouldn’t be surprised.

Relatively affluent, free of family responsibilities, and entertained by an array of media devoted to his every pleasure, the single young man can live in pig heaven — and often does. Women put up with him for a while, but then in fear and disgust either give up on any idea of a husband and kids or just go to a sperm bank and get the DNA without the troublesome man. But these rational choices on the part of women only serve to legitimize men’s attachment to the sand box. Why should they grow up? No one needs them anyway. There’s nothing they have to do.

Over at Ace of Spades HQ, the Regnerus article got Ace thinking:

A related thought I’ve had concerns feminists’ religious doctrine that social restraints on sexual behavior is all caused by grubby, oppressive, vagina-shackling men. This doesn’t make sense at all, and never has made sense, and is an unchallenged meme in the Grrls Rule, Boys Drool leftist feminist culture not because it makes a lick of sense but only because it hangs all the evils of the world on the Designated Sexual Villains in the feminist morality play. Men, of course.

If one accepts the hard-to-dispute premise that, between the sexes, women prefer a higher-sexual-cost regime in which men are supposed to “work for it,” as it were, and men prefer a lower-sexual-cost regime in which their sexual needs can be gratified with almost no work whatsoever (compare and contrast female wish-fulfillment romcoms with male wish-fulfillment pornos, or even James Bond movies, actually), then of course it makes sense that women, rather than men, have a sound motive for increasing the sexual penalties for promiscuous sex whereas men have stronger motive for decreasing them.

[. . .]

Leftist feminists of the younger, sillier generation similarly attempt to claim that it is evil, controlling men who use the word whore to not merely brand actual prostitutes but to control the sexual expressions of everyday women. That is, they assert (and these extremely silly third-generation feminists seem to write about little else but this) feel that social disapproval of female promiscuity is almost entirely a male invention, because men, you see, want to keep women from having sex with other men, so we invent the usage of the word “whore” to describe a sexually-liberated woman and by infecting the culture with this disease of whore-branding, make sexually-promiscuous women feel badly about their sexual choices and force them to conform to a male, Christian-fundamentalist (of course) regime of female chastity.

To the extent that women participate in this oppressive regime of whore-deeming, it’s only because a false conscience has been imposed upon them by male-dominated media. Women call other women “whores” not because women wish to wound other women (their sexual competition) but because men have hypnotized them to think this way.

To control their scary vaginas.

It nicely illustrates the confusion brought on by the social and sexual mores in flux:

As has been noted many, many times (not that lefty feminists ever notice), we did in fact have a Sexual Revolution, and men won. And the strangest thing about this is that lefty feminists, while claiming (and falsely believing) themselves to be liberating women, have in fact been eagerly liberating men, liberating men from the need of offering any kind of satisfactory trade-in-kind to women for sexual favors.

In their strange inversion of reality, it’s men who have the means, motive, and opportunity to increase the costs of obtaining sex and it’s women, on the other hand, who have the strong interest in a promiscuity and commitment-free (or even dinner-date free) sex.

And men, who, in this role-reversed alternate reality feminists have concocted, desperately want women to keep their vaginas chaste, can only be “beaten” by giving it all away for free.

And of course keeping abortion not only legal but socially praiseworthy because, again in this comic-book “What If?” issue of reality feminists have concocted, men only want to have sex to produce children and women, of course, are far less game for procreation, viewing sex as primarily a vehicle for erotic gratification. But that’s a dementia for another day.

Also interested enough to comment on the article was Monty:

. . . this cultural trend has left many men unsure about their place in the new order of things. The traditional role as primary breadwinner and head of the household has been removed, but nothing has come along to replace it. The predominantly-liberal media and entertainment complexes have spent decades denigrating men as hapless buffoons or abusive troglodytes. Modern Hollywood heart-throbs are not square-jawed heroes in the Gary Cooper mode, but rather thin, indolent, androgynous, and (most importantly) non-threatening. And while some women often wonder out loud “Where are all the decent men?”, there’s plenty of evidence at hand that given a choice, they’re still more attracted to the moneyed jerks of the world.

Monty also points out that there’s not just a strong set of hedonistic reasons pushing young men to stay in that “pre-adult” stage of life:

The big problem with modern heterosexual relationships is that apart from the sex, there’s really not much in it for men any more. Men have few legal rights over their own progeny; family law for decades has whittled away a man’s parental rights to little more than a financial obligation. If the woman already has children from a previous marriage, the man incurs an enormous burden in return for very little gain: in most cases he has no parental rights over the children, he competes for his wife’s time with the ex (and the ex’s family), and he incurs huge financial burdens but gains very little actual power in the household. A man’s sexual life is viewed with suspicion and sometimes disgust by women, who seem to want to train a man’s sex drive in the same way they train a naughty dog. A man alone with a small child is a man always on the verge of being accused as a child molester or abuser — society has made single men afraid to even approach children who are not their own (and sometimes even when the children are their own).

In short, men have been systematically demoted from their traditional place in society. This is good because it has given many women far richer and more interesting lives; but very bad because it has given men nothing in recompense. Women retained many of their old power-centers (child-rearing, home-making, etc.) but gained a lot of new power as well. For men, most of the change has been on the negative side of the ledger. From the male viewpoint, the only positive aspect of the change is that it’s much easier to have uncommitted sex, and even here the long-term harm far outweighs any short-term gains.

Men play video games, and watch sports, and hang out with their friends, because they enjoy it. It’s no more an “adolescent” activity for men than, say, shopping with their girlfriends is for women. Men do have complicated inner lives. They have hopes and dreams of their own that are not necessarily connected to the women they may be seeing. Men desire comfort and happiness in their lives no less than women do, but they seek it in different ways. Marriage — even a long-term relationship — has to benefit both partners, and in recent decades many men have simply found it to be not worthwhile.

Jon, who brought the original link to my attention, had this to say about the phenomenon:

How pervasive is this issue? I think the feminization of males is mostly a “big urban” thing, rather than universal. The closer you are to a dense urban centre, the more hipsters and girly males you seem to get. There seems to be an inverse square law happing here — the further away you get from the dense urban core, the fewer pansies you seem to find. Media and academics would have us believe that the fem-men in rural areas are simply closeted and are hiding their softer sides out of fear, but of course they would say that: they cannot conceive of the possibility that anyone outside of their own social environment might actually be different.

“SwordFit” – combining western martial arts with fitness classes

Filed under: Cancon, Health, Sports — Tags: , — Nicholas @ 09:02

This sounds like an excellent idea:

Since Devon Boorman opened the Academie Duello Centre for Swordplay in Vancouver seven years ago, he’s taught actors, fans of medieval weapons as well as bankers and office workers. Like an action-oriented Pilates class, the Western martial art of swordplay requires the grace of a ballet dancer with the strength of a warrior. It’s not about building muscle mass, as in weight-lifting, but about building plyometric — that is, explosive — strength.

But last fall, he added a new hybrid to his lineup.

The 90-minute SwordFit workout at Academie Duello is designed to be a mix of technical and cross-training, and features two instructors — one for swordplay and one for general fitness. Meghan O’Connell, the fitness instructor, has a background in boxing and has based many of the exercises on boxing training circuits.

[. . .]

“Swordplay makes you feel graceful and powerful at the same time — like dance,” Mr. Boorman says. It strengthens arms and shoulders, and tones the core. “If you relax your core,” he says, “your posture will crumple and you will lose your balance.”

Ms. Thomas also enjoys the couples aspect to the class. “I like the fact that we can take turns being the attacker and the defender,” she says. “It really gets a lot of frustration out.”

Mr. Thom agrees. “There’s something so visceral and revitalizing about the clanging of the swords.”

Views of a future that didn’t arrive

Filed under: History, Railways, Science, Technology — Tags: , , — Nicholas @ 11:35

The Future That Wasn’t: Failure to Perceive Hidden Costs and Risks

Two other entangled obstacles to technological inevitability must also be considered: unappreciated psychosocial reservations and genuine, but unappreciated hazards that either slow, or virtually inhibit the adoption of what would otherwise be hugely transforming technological advances.

As a child, I was told about what my future would be like and how much better it would be in almost every way, technologically, from the world I then inhabited. I was, literally, a child of the atomic age, and the molecules in the DNA of my brain still bear the 14Carbon isotope signature of the open-air nuclear testing era, just as surely as my bones, made radioactive in my infancy and childhood by the Strontium 90 (90Sr) in the milk I drank are still, ever so slightly, more radioactive today, than are those of people born before, or after, the era of atmospheric nuclear weapons testing.

But beyond these physical stigmata of the atomic age, my mind bears the stigmata of a world promised, but never delivered. Scientists and laymen alike were quick to understand the truly staggering potential benefits of what we now call nuclear power. Countless pronouncements were made that the arrival of an era of cheap, clean, safe, and virtually unlimited electric power was at hand. Electricity generated by ‘atomic power’ and nuclear fusion, we were told, would be so inexpensive to produce that it would not even be worth the expense of metering its use to bill the customer for. People would simply play a flat rate for the service, as is the case for long distance or computer telephony today. In a speech given by Lewis L. Strauss (1896-1974), Chairman of the U.S. Atomic Energy Commission to the National Association of Science Writers, in New York City on September 16th, 1954, Strauss commented on how scientific research then underway would transform life for the next generation of Americans, the generation that would be born in then and in the coming decade, my generation:

“Our children will enjoy in their homes electrical energy too cheap to meter…will travel effortlessly over the seas and under them and through the air with a minimum of danger and at great speeds, and will experience a lifespan far longer than ours, as disease yields and man comes to understand what causes him to age.”

The Santa Fe Railroad, then as commercially important and as technologically credible as Apple or Microsoft are today, anticipated fission reactor powered trains within 20 years, and ran ads in national magazines featuring a youngster only a few years older than me, asking to buy a ticket on an atomic powered version of the Super Chief which was then the preeminent way to travel across the country from Chicago to Los Angeles, in both speed and comfort.
