The Math of Pi Made Easy.

Why the hell don't they teach math this way?
Blogged without permission from http://opinionator.blogs.nytimes.com/2010/04/04/take-it-to-the-limit/?src=me&ref=general. Go read the damn thing yourself.

If you keep moving halfway to the wall, will you ever get there?
Something about this one was deeply frustrating, the thought of getting closer and closer and yet never quite making it. Another concern was the thinly veiled presence of infinity. To reach the wall you’d need to take an infinite number of steps, and by the end they’d become infinitesimally small. Whoa.

Questions like this have always caused headaches. Around 500 B.C., Zeno of Elea posed a set of paradoxes about infinity that puzzled generations of philosophers, and that may have been partly to blame for its banishment from mathematics for centuries to come. In Euclidean geometry, for example, the only constructions allowed were those that involved a finite number of steps. The infinite was considered too ineffable, too unfathomable, and too hard to make logically rigorous.

But Archimedes, the greatest mathematician of antiquity, realized the power of the infinite. He harnessed it to solve problems that were otherwise intractable, and in the process came close to inventing calculus — nearly 2,000 years before Newton and Leibniz.

Thanks to him, we have Pi.

Let’s recall what we mean by pi. It’s a ratio of two distances. One of them is the diameter, the distance across the circle through its center. The other is the circumference, the distance around the circle. Pi is defined as their ratio, the circumference divided by the diameter.

circle with diameter and circumference indicated

If you’re a careful thinker, you might be worried about something already. How do we know that pi is the same number for all circles? Could it be different for big circles and little circles? The answer is no, but the proof isn’t trivial.

The key to thinking mathematically about curved shapes is to pretend they’re made up of lots of little straight pieces. That’s not really true, but it works … as long as you take it to the limit and imagine infinitely many pieces, each infinitesimally small. That’s the crucial idea behind all of calculus.

Here’s one way to use it to find the area of a circle. Begin by chopping the area into four equal quarters, and rearrange them like so.

Four quarters of a circle on left, then rearranged on right

The strange scalloped shape on the bottom has the same area as the circle, though that might seem pretty uninformative since we don’t know its area either. But at least we know two important facts about it. First, the two arcs along its bottom have a combined length of πr, exactly half the circumference of the original circle (because the other half of the circumference is accounted for by the two arcs on top). Second, the straight sides of the slices have a length of r, since each of them was originally a radius of the circle.

Next, repeat the process, but this time with eight slices, stacked alternately as before.

Circle showing eight slices

The scalloped shape looks a bit less bizarre now. The arcs on the top and the bottom are still there, but they’re not as pronounced. Another improvement is the left and right sides of the scalloped shape don’t tilt as much as they used to. Despite these changes, the two facts above continue to hold: the arcs on the bottom still have a net length of πr, and each side still has a length of r. And of course the scalloped shape still has the same area as before — the area of the circle we’re seeking — since it’s just a rearrangement of the circle’s eight slices.

As we take more and more slices, something marvelous happens: the scalloped shape approaches a rectangle. The arcs become flatter and the sides become almost vertical.

Circle with many slices

In the limit of infinitely many slices, the shape is a rectangle. Just as before, the two facts still hold, which means this rectangle has a bottom of width πr and a side of height r.

Brilliant Social Commentary from South Park



South Park never ceases to amaze me when it comes to social commentary. In 2006, the writers had already correctly predicted that parents would eventually turn to the Dog Whisperer for tips against bratty kids.

At an early age, child brains are essentially primitive enough for psychological tricks and triggers to work- dog raising tips are would be a great idea. But the best part is, fast forward 3 years, The New York Times is finally catching on that parents are turning to the Dog Whisperer for parenting advice.

According to the NYT:

Today’s network lineup provides fewer idealized families and no shortage of questionable child-rearing role models (see “Gosselin, Jon”). For every take-charge SuperNanny, there’s a Homer Simpson, and who wants to raise a Bart?

It’s little wonder, then, that some parents, and even a few child therapists, have found themselves taking mental notes from a television personality known for inspiring discipline, order and devotion: Cesar Millan, otherwise known as the Dog Whisperer.

The suggestion that the Dog Whisperer is also a Child Whisperer of sorts has popped up — sometimes couched as a joke, but, well, not really — in parents’ forums like blogs, online discussion boards, magazines, Twitter feeds and podcasts. Some parents are starting to take notice.

“When we started watching his shows, we had intended to apply his advice toward our dogs,” said Amy Twomey, a blogger on parenthood for The Dallas Morning News who is raising three children under 10 with her husband, Matt. “But we realized a lot of ideas can be used on our kids.”

The Redeeming and Condemning Power of Facebook

Available exclusively on AugustMan Magazine Facebook
Click here to Join the AUGUST MAN Facebook Page

On Oct 17, 2009 at 11.49 am, 19-year-old Rodney Bradford asked where his pancakes were. At that very moment 24 kilometres away, a robbery was in progress, a robbery that witnesses said Bradford committed.

Yet for all the damning evidence, that man who looked remarkably similar to Rodney, wasn't him. Rodney was in his father's apartment in Harlem on Facebook, writing a status update, "Where my IHOP (International House of Pancakes), yo?"

However insipid and lame this update was, it saved Rodney jail time as police proved through an IP search in cooperation with Facebook that Rodney was, indeed, at home.

Just yesterday, in Bromont, Quebec, Nathalie Blanchard found herself under similar scrutiny. This time around, Facebook did not play exonerating saviour. Nathalie was supposed to be on long-term sick leave and medical benefits for depression from IBM. However, Facebook photo albums proved otherwise.

She was "tagged" at Chippendales, enjoying her birthday party and on a sun holiday. Although Manulife wouldn't comment on the Blanchard case, Nathalie's benefits have since been terminated.

The Internet and all its ubiquitous social media marvels like Friendster, MySpace and Facebook have become so intimately entwined in our lives that authorities and higher management alike have begun to use trawled "evidence" from these once-considered parasitical outlets.

My issue isn't that the Internet is being used increasingly as a character reference on us, but rather, as we head into a dystopian Minority Report kind of future, should we not, as intelligent beings exercise more caution on our vanity?

Vanity indeed. All your status updates are simply based on a premise that somewhere among your 500 friends, someone gives a damn. When you post pictures, it provides proof that you were indeed at Club Ibizia last night.

As bosses and seniors start to get on the social media bandwagon, it's perhaps time to start thinking a little more before you post your masturbatory updates, especially when last night you promised the boss you'd be working on the $2 million dollar project rather than partying at Club Ibizia. I for one, would be a little more careful on informing my friends I just killed Gildamesh the Orc King on Castle Age. - JH

The End is Nein

Exclusive from Facebook: AugustMan Magazine

2007- Fallout 3. Bethesda Softworks LLC. All Rights Reserved.

Nein. Non. No. The End is definitely not nigh.

For a man who's destroyed the world three times over, Roland Emmerich is making tons of money. And what is the director of celluloid disasters such as Independence Day and The Day before Tomorrow, going to do with all the money that he can't possibly spend during the End of Times?

For that matter, even Jehovah's Witnesses, those persistent (annoying) evangelists have stopped their traditional (since 1874) apocalyptic prophecies when they botched it up again for the last time 1975.

Humanity seems intent on marking every significant historical milestone with apocalyptic ideologies. When the United Nations was formed, biblical doomsayers were quick to point out that the beginnings of this world government was a sign of the end of times. Truth be told, we have it on good information from "reputable" sources that the world's probably been ending since 99 AD. Well, here's the good news- It's not over and we're still here.

Here's our tip for you astute August Men out there, when friends bug you to spend $9 on Roland Emmerich's 2012, smile and tell them to turn on the news. Disasters happen everyday and the ones on CNN have special effects more realistic than anything Roland can throw at you. -JH

Whatever is popular on TV now not only sucks but bites

Exclusive for AugustMan Magazine on Facebook

Getty Images: Zombie- Fans perform Thriller

Vampires. There's a media frenzy around bloodsuckers - Just look at True Blood on HBO (Max for Singaporeans), Twilight part deux coming out in the theatres and the Vampire Diaries. In fact, just not too long ago, Buffy was traipsing around on our television screens gleefully staking them in cheerleader outfits and cheesy lines.

Even if we move away from the blood sucking spectrum, we're still looking at flesh eating zombies in Zombieland. The latest offering from Hollywood features a lone nerd surviving the zombie infested plaguelands of the former US of A.

Wherever we are, it appears humanity has a morbid fascination with the undead - just look at Hollywood's latest horror (pun intended), Paranormal Activity.

Perhaps the truth is closer to the surface. Vampires never eat, they're eternally youthful, wrinkle-free and we've never seen an ugly vampire- isn't that the stuff of fashion fantasy?

Death simultaneously attracts and repels us. We spend billions to erase signs of aging and even turn to organ replacement to extend life. If there's a chemical or alchemic concoction for it, society will spend its energy making, advertising, and consuming.

What of zombies? A zombie apocalypse gives us the benefit of a fresh start. A powerful time to remake one's identity, not to mention opportunity to allow our ids to surface in a land of lawlessness. A thief can become the gun-toting saviour who rescues trapped survivors from meat eating chompers and a saint can become a satanic survivalist who would do anything for self-preservation.

Ultimately, whether you like zombies, ghosts or vampires, it all falls back to the human condition- we're all looking for a sense of self unrestrained by social norms and mores, and that’s really creepy.

The growing power of Men's Rights

"Men's Rights" Groups Have Become Frighteningly Effective

They’re changing custody rights and domestic violence laws.

At the end of October, National Domestic Violence Awareness Month, members of the men’s movement group RADAR (Respecting Accuracy in Domestic Abuse Reporting) gathered on the steps of Congress to lobby against what they say are the suppressed truths about domestic violence: that false allegations are rampant, that a feminist-run court system fraudulently separates innocent fathers from children, that battered women’s shelters are running a racket that funnels federal dollars to feminists, that domestic-violence laws give cover to cagey mail-order brides seeking Green Cards, and finally, that men are victims of an unrecognized epidemic of violence at the hands of abusive wives.

“It’s now reached the point,” reads a statement from RADAR, “that domestic violence laws represent the largest roll-back in Americans’ civil rights since the Jim Crow era!”

RADAR’s rhetoric may seem overblown, but lately the group and its many partners have been racking up very real accomplishments. In 2008, the organization claimed to have blocked passage of four federal domestic-violence bills, among them an expansion of the Violence Against Women Act (VAWA) to international scope and a grant to support lawyers in pro bono domestic-violence work. Members of this coalition have gotten themselves onto drafting committees for VAWA’s 2011 reauthorization. Local groups in West Virginia and California have also had important successes, criminalizing false claims of domestic violence in custody cases, and winning rulings that women-only shelters are discriminatory.

Groups like RADAR fall under the broader umbrella of the men’s rights movement, a loose coalition of anti-feminist groups. These men’s rights activists, or MRAs, have long been written off by domestic-violence advocates as a bombastic and fringe group of angry white men, and for good reason. Bernard Chapin, a popular men’s rights blogger, told me over e-mail that he will refer to me as “Feminist E,” since he never uses real names for feminists, who are wicked and who men “must verbally oppose … until our flesh oxidizes into dust.” In the United Kingdom, a father’s rights group scaled Buckingham Palace in superhero costumes. In Australia, they wore paramilitary uniforms and demonstrated outside the houses of female divorcees.

But lately they’ve become far more polished and savvy about advancing their views. In their early days of lobbying, “these guys would show up and have this looming body language that was very off-putting,” says Ben Atherton-Zeman, author of Voices of Men, a one-man play about domestic violence and sexual assault. “But that’s all changed. A lot of the leaders are still convicted batterers, but they’re well-organized, they speak in complete sentences, they sound much more reasonable: All we want is equal custody, for fathers not to be ignored.”

One of the respectable new faces of the movement is Glenn Sacks, a fathers' rights columnist and radio host with 50,000 e-mail followers, and a pragmatist in a world of angry dreamers. Sacks is a former feminist and abortion-clinic defender who disavows what he calls “the not-insubstantial lunatic fringe of the fathers’ rights movement.” He recently merged his successful media group with the shared-parenting organization Fathers and Families in a bid to build a mainstream fathers' rights organ on par with the National Organization for Women. Many of Sacks’ arguments—for a court assumption of shared parenting in the case of divorce, or against child-support rigidity in the midst of recession—can sound reasonable.

But do any of their arguments hold up? Many of the men for whom Sacks advocates are involved in extreme cases, says Joanie Dawson, a writer and domestic-violence advocate who has covered the fathers’ rights movement. The great majority of custody cases, in which shared parenting is a legitimate option, are settled or resolved privately. But of the 15 percent that go to family court—the cases that fathers’ rights groups target—at least half include alleged domestic abuse.

Unsurprisingly, this argument is missing from MRA discussions of custody inequality and recruitment ads, which cast all men as potentially innocent victims “just one 911 call away” from losing everything they have earned and loved. These rallying calls, and the divorce attorneys hawking men’s rights expertise on MRA sites, promising to “teach her a lesson,” serve as what Dawson sees as a powerful draw for men in the midst of painful divorces.

While MRA groups continue to expand their base of embittered fathers and ex-husbands, they’ve cleaned up their image to court more powerful allies. RADAR board member Ron Grignal, the former president of Fathers for Virginia and a former state delegate candidate, organizes the group’s Washington lobbying activities. In 2008, RADAR partnered with Eagle Forum for a conference at the Heritage Foundation about the threat that VAWA poses to the family. Grignal argues that state interpretations of VAWA are so broad they could cast couples’ money disputes as domestic violence, enabling unwarranted restraining orders that then win women’s divorce cases for them. Politicians, Grignal says, are increasingly on board with men’s rights movement concerns.

“On domestic violence, I’ve had both state and federal legislators tell me they know that this process is out of control,” says Grignal. “They’re afraid if they support [reforms] they’ll be tagged as ‘for domestic violence.’ But I’ve had Democrats on Capitol Hill tell me they agree with everything I say. A member of the Congressional Black Caucus told me that his brother can’t see his kids, and his wife threatened to throw herself down the stairs to ruin his political career.”

Some domestic-violence protections do seem to have unintended effects, such as mandatory-arrest policies that compel police to take someone into custody in response to any domestic-violence call—a policy that has been criticized by RADAR as well as by some domestic-violence advocates, who say it imposes an absurd equivalence between largely nonviolent family spats or insubstantial female violence and serious abuse. But groups like RADAR are criticizing the law for the wrong reasons. In fact, the effect of mandatory arrest in conflating women’s low-level violence with battery, seems very close to RADAR’s campaign for viewing women as equal domestic abusers.

One potent idea advanced by MRAs is the claim that men are equal victims of domestic violence. Mark Rosenthal, president and co-founder of RADAR, makes a very personal argument for the phenomenon. Rosenthal, who doesn’t call himself an MRA, grew up with a mother who he says terrorized the entire family and hit her husband frequently. The true impact of the violence, he says, was more than physical and eclipsed his petite mother’s ability to inflict serious injuries. Rosenthal wants to see an appreciation for women’s nonphysical abuse incorporated into domestic-violence policy. “It’s not about size,” he told an audience at a law enforcement domestic-violence training. “It’s not exclusively about physical attacks. However, it is about a pathological need to control others, and women are as prone to this as men.”

RADAR and other MRA groups base their battered men arguments largely on the research of a small group of social scientists who claim that domestic violence between couples is equally divided, just unequally reported. Most notable are the studies conducted by sociologist Murray Straus of the University of New Hampshire, who has written extensively on female violence (and who Dawson saw distributing RADAR flyers at an APA conference). Straus’ research is starting to move public opinion. A Los Angeles conference this July dedicated to discussing male victims of domestic violence, “From Ideology to Inclusion 2009: New Directions in Domestic Violence Research and Intervention,” received positive mainstream press for its “inclusive” efforts.

While some men certainly are victims of female domestic violence, advocates say the number is closer to 3 percent to 4 percent, rather than the 45 percent to 50 percent RADAR claims. Jack Straton, a Portland State University professor and member of Oregon’s Attorney General's Sexual Assault Task Force, argues that Straus critically fails to distinguish between the intent and effect of violence, equating “a woman pushing a man in self-defense to a man pushing a woman down the stairs,” or a single act of female violence with years of male abuse; that Straus only interviewed one partner, when couples’ accounts of violence commonly diverge; and that he excludes from his study post-separation violence, which accounts for more than 75 percent of spouse-on-spouse violence, 93 percent of which is committed by men.

All in all, advocates say that cherry-picked studies from researchers like Straus, touted by the MRAs, amount to what Edward Gondolf, director of research for the Mid-Atlantic Addiction Research and Training Institute, calls“bad science.” Statistics suggesting gender parity in abuse are taken out of necessary context, they say, ignoring distinctions between the equally divided “common couple violence” and the sort of escalated, continuing violence known as battery—which is 85 percent male-perpetrated—as well as the disparate injuries inflicted by men and women.


“The biggest concern, though, is not the wasted effort on a false issue,” writes Straton, but the encouragement given to batterers to consider themselves the victimized party. “Arming these men with warped statistics to fuel their already warped worldview is unethical, irresponsible, and quite simply lethal.”

In this, critics like Australian sociologist Michael Flood say that men’s rights movements reflect the tactics of domestic abusers themselves, minimizing existing violence, calling it mutual, and discrediting victims. MRA groups downplay national abuse rates, just as abusers downplay their personal battery; they wage campaigns dismissing most allegations as false, as abusers claim partners are lying about being hit; and they depict the violence as mutual—part of an epidemic of wife-on-husband abuse—as individual batterers rationalize their behavior by saying that the violence was reciprocal. Additionally, MRA groups’ predictions of future violence by fed-up men wronged by the family-law system seem an obvious additional correlation, with the threat of violence seemingly intended to intimidate a community, like a fearful spouse, into compliance.

MRA critics say the organizational recapitulation of abusive tactics should be no surprise, considering the wealth of movement leaders with records or accusations of violence, abuse, harassment, or failure to pay child support. Some advocates call MRA groups “the abuser’s lobby,” because of members like Jason Hutch, the Buckingham Palace fathers’ rights “Batman,” who has been estranged from three mothers of his children and was taken to court for threatening one of his ex-wives.

Contrary to RADAR’s claims, domestic-violence advocates say that not only do abuse accusations not automatically win custody cases for women; there are a rising number of custody decisions awarded to abusive fathers, as judges see wives eager to protect their children as less cooperative regarding custody. More than half the time, studies have found, wives’ accusations of domestic violence are met with counter-accusations from husbands of “Parental Alienation Syndrome”—a medically unrecognized diagnosis that suggests mothers have poisoned their children into making false accusations against their fathers.

In one recent case, Genia Shockome, a Russian immigrant, was fighting for custody of her two children with her ex-husband, whom she charged had beaten her so severely that she suffered post-traumatic stress disorder and who had told her she “had no right to leave” since he’d brought her to the United States. The judge in the case sided with her husband’s counter-claims of Parental Alienation Syndrome and awarded him full custody (and later sentenced Shockome to 30 days in jail while she was seven months pregnant). When her attorney, Barry Goldstein, co-author of the forthcoming book Domestic Violence, Abuse and Custody, criticized the judge in an online article, the judge retaliated with a complaint, and Goldstein was given a five-year suspension. Goldstein says the sanction represents a chilling pressure on attorneys, who may now fear penalties for criticizing a court’s gender bias that will interfere with their duties to their clients and that could result in women deciding not to leave abusers out of fear they won’t get a fair trial.

If cases such as Genia Shockome’s are the fodder of mainstream fathers’ rights advocates like Glenn Sacks—who ridiculed her claims and loss of custody as an uncredible “cause célèbre” for feminist family-law reformers—what Sacks calls the movement’s “lunatic fringe” is more vitriolic yet.

Within the ranks of the men’s rights movement, vigilante “resisters” are regularly nominated and lionized for acts of violence perceived to be in opposition to a feminist status quo. In a few quarters of the movement, this even included George Sodini, the Pittsburgh man who opened fire on a gym full of exercising women this August, killing three and leaving behind an online diatribe journaling his sense of rejection by millions of desirable women.

Sodini’s diary was republished widely, including on the website of a popular men’s rights blogger, “Angry Harry,” who added his assessment of the case. “MRAs should also take note of the fact that there are probably many millions of men across the western world who feel similar in many ways, and one can expect to see much more destruction emanating from them in the future,” he wrote. “One of the main reasons that I decided to post this diary on this website was because the western world must wake up to the fact that it cannot continue to treat men so appallingly and get away with it.” In a phone interview, Angry Harry said, “Of course there will be more Sodinis—there will be many more,” likening him to Marc Lépine, a Canadian man who killed or wounded 28, claiming feminists had ruined his life, or Nevada father Darren Mack, who murdered his estranged wife and attempted to kill the judge in their custody battle. (Also among this number is John Muhammad, the “D.C. Beltway Sniper,” whose involvement in a Washington father’s rights group and history of abuse is described in his ex-wife Mildred’s newly-released memoir, Scared Silent.) Perhaps, Angry Harry mused, that as the ranks of online MRAs grow, “the threat” of their violence “may be enough” to bring about the changes they desire.

Glenn Sacks dismissed Angry Harry as an "idiot" without real power in the movement, and yet he cautiously agrees that what Sacks calls "family court injustices" could lead to future violence.* “I want to be careful in wording this,” he says, “but the cataclysmic things I’m seeing done to men, it’s always my fear that one of these guys is going to do something terrible. I don’t want to say that like I condone it or that it’s OK, but it’s just the reality.” The movement seems eager to supply more martyrs. After Sacks wrote about a San Diego father who shot himself on the city’s courthouse steps over late child-support payments, numerous men wrote Sacks, telling him, “They’re taking everything from me, and I want to go out in a big way, and if I do, will you write about me?”

I asked RADAR’s Mark Rosenthal about the ties between groups like RADAR—claiming, however cynically, to have egalitarian motives—and the blunt anti-feminist positions of men’s movement allies like Chapin or Angry Harry. “I’d like to suggest that what you’ve just done is interview Martin Luther King and Malcolm X,” he told me. “In any movement, there is going to be a reasonable voice and people who are so hurt, who are so injured by the injustices, that they can’t afford to step back and try to take their emotions under control. But no movement is going to get anywhere without extremists.”

*Clarification, Nov. 6: This article originally said that Glenn Sacks "cautiously defends" Angry Harry. In fact, he "cautiously agrees that what Sacks calls 'family court injustices' could lead to future violence."

Correction, Nov. 9: This article orginally mislabeled the National Organization for Women as the National Organization of Women.

Beyond the Iron Curtain

This article will always be a source of pride for me. Yes. I do write for AugustMan now.


Twenty years have passed since the Berlin wall came down. And while the world gathers to commemorate the end of the cold war and the reunification of the once divided nation, one wonders how much has changed, if at all.

Economically, Berlin had been designated a test bed of free-market "western" capitalism and centrally-managed planned communist economy. East and West Berlin, both culturally and economically alike at the end of World War II were split between Russia and the remaining Allied Powers.

For all intents and purposes, human flight from East to West has stood testament to the strength of free-market ideologies. West Germany, propelled by capitalist ideals, progressed into an industrial and economic powerhouse while East Germany, continued to stagnate essentially becoming a time capsule of 1950s products and architecture.

Indeed, little has changed. We are still in an absurd arms race, conflicts are still fought on ideology albeit of a different nature and most importantly, the recent global financial meltdown is proof enough that the free-market isn't exactly the stellar example of economic theory.

The world hasn't become a fairer place. Disparities in wealth continue to exist globally and even within national boundaries. The physical demolition of a schism hasn't proven that centrally managed economies are doomed to fail. It has only shown that given enough time, the selfish actions within a free market can doom the rest of us to economic failure.

Yet for all the gloom, we can still take comfort in the fact that the wall's fall was the result of the human will for change and reform. That ideologies of any kind divide and separate. That in order for us to progress, we must question once-indisputable "truths” and cast light on blind faith. That ultimately, the utopian future, lies in our hands and not in the hands of our leaders. We must want heaven for ourselves.

How a Blunder finished off a Wall

This article belongs to the BBC. I've saved it for reference.

When the Berlin Wall opened on 9 November 1989 Brian Hanrahan was the BBC News reporter on the ground. This year he's been back to talk to some of those whose decisions made this key moment in 20th Century history possible.

From the safe distance of 20 years, the opening of the Berlin Wall can be seen as inevitable - the natural consequence of changes that were reshaping Europe. But for most of 1989 it was unthinkable.

And the decision itself was an accident - intended neither to happen the way it did nor to spark off the tumultuous changes that followed.

I heard the inside story of what started this extraordinary rush of events from one of those who made the decision in the East German Politburo - the communist party's ruling body.

Hans Modrow was a communist reformer in the Gorbachev mould. He had only just been given a place on the Politburo as East Germany's leaders tried to head off the demands for change that were sweeping the country. But as a new boy his opinions counted for little.

He remembers an agitated discussion about the travel restrictions - the laws which banned most East Germans from leaving the country and which had sparked off the popular discontent.

At the end of it the party leader, Egon Krenz, suddenly produced a new set of regulations. From now on it would be much easier for East Germans to travel.

What annoyed Mr Modrow was the autocratic way in which the Communist Party still did business. "We couldn't change anything, he says, We sat there like stupid little boys. We just had to do what we were told."

'Blurted out'

But now came a blunder that would bring down the Berlin Wall and the East German state with it.

The intention was to announce the changes overnight and phase in the new rules the next morning. Instead one of the Politburo members, Guenter Schabowski, blurted out the plans during a televised press conference - and compounded his error by adding the new rules would come into force "immediately".

Live press conferences were a novelty in communist days, and Mr Schabowski was becoming something of a celebrity through his appearances. Mr Modrow is still scathing about Mr Schabowski's preening in front of the media.

"The order wasn't to be published until 0400 in the morning. But Mr Schabowski didn't notice. He went into an international press conference. And he was so arrogant and full of himself. We had no idea this was happening."

Mr Schabowski's announcement was complicated and bureaucratic, and like many others that evening I puzzled over it before concluding that it signalled free travel. If this was true it would mean the end of the Berlin Wall because the whole fearsome structure with its watchtowers, barbed wire and guard dogs had become redundant.

East Berliners were rather quicker off the mark. Tens of thousands of them started turning up at the border demanding to be let across.

But the guards hadn't been told anything - their standing orders were to stop anyone crossing. Until recently they'd been instructed to shoot to kill anyone who tried.

This night they tried to turn people back - but after a generation being pushed about Berliners turned belligerent and refused to go.

Stunned guards

The standoff between the armed guards and the angry crowds soon grew tense and dangerous.

The guards asked their headquarters for orders but the government ministries in charge of security told them nothing. Mr Modrow and the other Politburo members had gone home unaware of what was going on.

With radio and TV reports bringing more people on to the streets, Mr Modrow says it was the border guards themselves who decided what to do.

"With hindsight it's the border guards we must thank, not any of us in the Politburo. The guards on the ground - at the time - made the critical decision. They ignored their standing orders. They said, 'Open the border.'"

I arrived at the main border post just in time to see the barriers swing open as the guards gave up any attempt to regulate the crossing. They looked stunned at the mass of people streaming past them. Their whole world was collapsing about them.

But if East Germany's leaders were ignorant of what was happening, the rest of the world was already watching on television.

In Washington, James Baker was at lunch with the President of the Philippines, Cory Aquino, when he was told the news. A short while later, hearing that people were taking sledgehammers to the wall, he abandoned the table and hastened over to the White House.

Changed world

There he and President Bush were taken aback at what they saw. They'd had no warning. "It was happening before our eyes. Maybe the Soviet leadership saw it coming but I don't think anyone in allied capitals anticipated it happening with that speed."

And Mr Baker admitted candidly that he was daunted by the scale of the task ahead in reshaping world alliances. As the West's chief diplomat he would have to do most of it. "The world as I had known it all my adult life changed that day, and it changed fundamentally. I had grown up with the Cold War. Everyone in my generation had."


In the Kremlin the man most responsible for the change slept through it. The Soviet leader had been tipped off a few days earlier about the way the East Germans were thinking.

Mr Gorbachev chuckled as he remembered the rush to tell him what had happened. "They reported to me quite early in the morning. They were in a hurry to let me know. We had been expecting it to happen. It could have happened at any time."

And he was matter-of-fact about the consequences. "I took note of the report. It moved us on to a new phase. Not that I was enthusiastic about it, but I accepted it as something that had to happen. We understood that the time was coming for the German problem to be addressed."

In London Douglas Hurd had been foreign secretary for just 15 days. He noted the news from Berlin in his diary. "The regime and now the wall are crumbling fast," he wrote. But he was already wondering how he could persuade the Prime Minister, Margaret Thatcher, to consider the idea of a united Germany.

Berliners were only just opening the bottles of sparkling Sekt at the beginning of a street party that would last for days. Many were still uncertain what exactly was happening.

But in a few short hours they had changed the contours of world politics and there could be no going back. The inevitable, unthinkable accident had happened.

If I should be so lucky

I'm guessing if it was a local couple, they'd be going:
HUAT AH!

BREAKING NEWS: OOPS..

I was wondering, since Mdm. Ho Ching has stepped down, couldn't she just clear leave like every other employee in the country (isn't that what we do after tendering our resignation)? Rather than make half-crocked decisions to "Buy high and sell low"?

According to the NEW YORK TIMES:
Analysts at Goldman raised BofA from neutral to buy and added the company to their so-called conviction list of recommended stocks. Analysts at Citigroup kept a buy rating on the shares, but had positive things to say about the integration of BofA and Countrywide, the troubled mortgage lender it recently bought, as well as its capital-raising plans.BofA is using “at-the-market” stock sales to raise a large part of its additional capital cushion. That means the shares are quietly dribbling out in unknown quantities. Reading the tea leaves — and watching the volume of BofA stock trades — analysts at Citi, led by Keith Horowitz, estimate it has already raised $3 billion to $4 billion from selling new stock.
But Temasek, the investment arm of Singapore, could be feeling a bit of seller’s remorse. The fund recently reported selling its entire stake in BofA — at an enormous loss, by all accounts — some time before March 31. Since then, BofA’s stock is up about 74 percent.

OOPS..

From TODAY Online: MP had no empathy

It started with Member of Parliament (MP) Seng Han Thong being set on fire. Then came MP Denise Phua who was threatened by a rag-and-bone man. Recently, MP Cynthia Phua was subjected to a display of violence by a constituent.

Although these incidents are disturbing and a cause for concern, I wonder whether the constituents are solely to be blamed.

Allow me to relate my personal experience.

In February 2001, my older son died in a naval accident whilst serving National Service. In that year, my younger son was due for enlistment. A friend, a very active grassroots member, suggested that I approach my MP, for help in exploring the possibility of getting an exemption for my younger son. I was reluctant but he went ahead to fix an appointment for me at the Meet-The-People Session (MPS). I subsequently relented and he accompanied me there. It was in March 2001. That was my first appearance at a MPS, and it was to be my last.

I waited until midnight before I could meet the MP. Prior to this, he was given the case paper which detailed the objective of the meeting and the circumstances of my case.

When I entered the room, his first remark was “Yes, what can I do for you?”. There was no attempt at offering a word of sympathy or condolence. I then related my situation and said that both my wife and I were very traumatised.

His next remark “What traumatic, after two months, you won’t be traumatic?”. With that, I decided to end the meeting. And with that, my respect for him hit ground zero. I was too stunned and grief-stricken to react. Someone who was less-controlled and less-measured than me could have flown into a rage and become violent.

MPs are elected or appointed to serve the constituents. People who attend the MPS are those who have real problems and need help. In a lot of instances, they are stressed, distressed and troubled. What they need is a caring soul, a helping hand, a gentle voice, and words of hope and encouragement. To dispense these, MPs need good interpersonal skills and a high EQ. Arrogance, a patronizing, chiding and belittling attitude, aloofness and lack of empathy will only trigger acts of rashness and violence. Many of our politicians have a high IQ, some are scholars. However, a high IQ is not the only attribute needed in a political career. A high EQ is equally, if not more critical, especially when it comes to dealing with the constituents.

In my case, I would have felt good if my MP could have been a warm and caring person. If he could have been empathetic, consoling and helpful. All these qualities can only come from the heart, not from the mind.

How many of our MPs can stand up and be counted for this?

The Scourge of Nigerian Scammers

I salute these guys :)

Taken From Ars Technica- Click title for original article. Excerpt below:

When your hobby is baiting 419 scammers (also known as Nigerian scammers or advance-fee fraudsters), a death threat isn't cause for concern—it's a trophy worth bragging about to your friends.

Scam baiters are the vigilante enforcers who come together to waste hours, weeks, or months of 419 scammers' lives for nothing more than the satisfaction of knowing that they are distracting them from real victims. Though the world of 419 scams has existed since long before the Internet, people continue to fall for scammers in droves—certainly, scammers are making millions of dollars every year by promising money, goods, and romance that they never deliver on. That's part of why scam baiting has actually become a somewhat popular pastime online, with thousands of users flocking to scam baiting forums to share stories and ideas on how to string along more scammers. And hey, why not? Most of us end up spending too much time screwing around on the Internet anyway—these folks just use that time to make scammers miserable.

But when you hear stories like this, it makes you wonder. "I get death threats on regular basis," a student who goes by -C- told Ars. "Death threats are not uncommon and are actually considered achievements: they are a testament to the fact that the baiter managed to annoy his/her scammer nicely."

Star Trek and a review of Inadequate 23rd century tactics

fcintro03

Twenty-third century warfare isn’t all it’s cracked up to be. You’d think that weapons and tactics would have progressed in 200 years. But the new Star Trek movie shows that the United Federation of Planets has a lot to learn about warfare.

A military analysis of young Cadet Kirk’s War isn’t easy. Director J.J. Abrams‘ frenetic rock ‘em, sock ‘em style can be tough to follow. But here is Star Trek’s vision of future warfare. (Warning: all sorts of spoilers ahead.)

From Wired.com. Click here to read more.

That said, Star Trek was a rocking good movie sans plot and moralistic introspection (not really a bad thing). Die hard Trekkers will dislike the giant continuity problems that will ensue as a result of MASSIVE history altering events (hint: the United Federation of Planets suffers loss of a homeworld of one of its founding members) and the non-Trekkers will find the movie a good reason to look up "continuity" Trek TOS (original series) and TNG (Next generation).

The latest incarnation of Star Trek is Star Trek:Nemesis on crack. Nemesis was action focused but as usual, attempted to slide in a cautionary tale on evolutionary biology, cloning and whether the actions of ones' clones are a reflection of the original.

This "reboot" turns Trek history on its head with the death of James T. Kirk's inspiration to join Starfleet- his father. George Kirk takes command of the USS Kelvin for 12 minutes and successfully enacts a holding action against a vastly technologically superior time-traveling Romulon Mining Ship (why a mining ship is so heavily armed is a mystery to me.. but then again, they're Romulon..), saving his wife, newborn son and 800 others. And that's where history splits, Jim never joins Starfleet till a chance meeting with Christopher Pike (first commanding officer of the constitution class Enterprise. NERD ALERT: Robert April is the first CO.. but it's a reboot..).

Commander Spock rises swiftly through the ranks and is actually given Captainhood of the Enterprise when Pike has to meet Nero face to face, Pike's last orders assign Kirk to Spock as First Officer.

The movie will continue to place die-hard "OMG continuity" Trekkers in a very uncomfortable position- the joy of watching their boyhood hero grow to fill the Captain's chair and the inevitable pain that comes from watching a founding member's homeworld go kablooey.

But nevertheless, watching my girlfriend ooh and aah at the spiffy updated constitution Enterprise bridge controls and phased laser point defense systems, I was under no doubt that this was the Trek movie that would turn previously non fans, fans.

JJ Abrams has tastefully included the bridge sound artefacts from the original series (whee.. whee.. whee..) and finally proven the purists that- THERE IS NO SOUND IN SPACE with a viscereal 10 minute combat sequence that cuts from "pew-pew-kabloom" ship exterior to ship interior at the precise moment where a bulk head explodes, flushing a crewwoman into the silence of dark space.

Overall, it's a mast watch (nautical joke). 4.5 out of 5 stars.

P.S. I might catch it again. The sound FX and soundtrack are worth every penny.

Bible Thumping

You can read the inspiration for this post here.

Definitely not a pro-pornography post (but hey, like any hot blooded male, I do enjoy a voyeuristic romp), but just some simple thoughts on those that use the Bible to condemn all manner of behavior.

Please have a read through on the typical "evils" of pornography
(not my opinions btw)

Around 10 percent of all adults (not statistically proven) who engage in viewing pornography feel that they are addicted. These are self-reports of men and women who cannot stop viewing pornography. The consequences of pornography addiction (dependence) may not always be clear, but let me list a few consequences:
  • Separation and divorce
  • Being unavailable to children
  • Job loss
  • A fiance ending the relationship
  • An increased tendency to argue
  • Lack of trust in relationships
  • Sexually acting out
While many argue that pornography is a matter of freedom of speech, they are missing the point. Pornography hurts people. Do you really wonder who it hurts? It hurts marriages. It hurts the individuala who become addicted. Those caught in this addiction are likely to be depressed and feel out of control. They will not be as focused in their relationships with other halves.

If you aren't anti-pornography - you might want to consider the social implications that pornography is having upon all of us. It is time to wake up and realize that pornography is destroying far too many good men and women's lives. "

He then went on to quote the bible, to back up what he was saying.
I find this situation rather typical in present day interactions with a typical christian. In this instance, when I say christian, I'm excluding Catholics (though we're part of the same family).
Catholics can be depended upon to mind their business, their relationship is between God and themselves (the Pope being the exception as he continually shoots his mouth off. He speaks for the religion but not for the majority of practicing Catholics).

Back on point- It's my opinion and experience that increasingly Christians around the globe have taken to "bible thumping". In this instance, they've targeted pornography. Not too long ago, Singaporean Christians set their sights on homosexuality- Be aware of MORONS in Aware.

Firstly, I've mentioned that marriage as an institution is no longer as sacred as it used to be. Secondly, as a biblical foundation, marriage was something instituted by the Catholics (Vatican council) to be precise. For those of you who are family with King Henry VIII, his conflict with the Holy See over marriage and divorce essentially led to the splinter from Holy Leadership in Rome and gave birth to the Church of England (Anglican Catholicism). My point is that the man-made foundations (decided by men; females weren't involved in the decision making) for this institution is the reason for its high failure rates.

Through the ages, marriage success is and continues to be a major factor in how we are judged. People are pressured into marriage even today by social norms and mores. In the local context of Asian Singapore- there's a greater emphasis of "waiting for the right time (e.g. after graduation)" rather than "waiting for the right one."

As a student of human social dynamics, it's my opinion that marriages are failing, because it's not natural. And the failure rate is compounded when many (particularly Singaporean females) pressured into finding someone and as a result don't take the time to find the right one.

Raise of hands, those of you who are familiar with the following statements:
  • He was nice so I stay with him lor.
  • He was persistent. Always chasing me, so I gave in.
  • Together 7 years already, get married lor.
When girls tell me this, it really doesn't speak about how madly in love they are with their partners. It just tells me how insecure and how badly in need of adoration many Singaporean girls are.

And in the end, Singaporean hen-pecked men resent their wives, Singaporean women, hate their unromantic unwitty husbands (enter the Ang-moh), do you really think this is all because of porn?

Now think about how many people have been duped into believing that they must go and make it "official".

Some have claimed that the bible is a highly flawed book and when the entire institution of marriage is based in the bible, where does that leave us?

Biblical "Marriages"
They would see a priest (one from the tribe of Levi) to get permission and blessing. the man would do this. then he would go to the woman's family and buy her, of course she was only acceptable if she was a virgin.

It's only a marriage after it's been consummated. This is where the whole "tradition" of "you may kiss the bride" arises. In days of old, the village or village elders are present at the consummation to stand witness to the virginity of the bride, the evidence: Blood on the marital sheets.

Bible refers to post-marital sex as "and he knew her" so when a man knows this woman, by having sex, she becomes his wife.

Biblically (Christian, Torah & Quran), a man could do this with as many women as he could afford to keep. Solomon had 700 wives, and 300 slave women.

This was cool with God. All the key people in the bible had more than one wife; I've looked it up, you should too.

Having read the basis of marriage, reconsider the hypothesis that Porn is the reason for divorce. For all intents and purposes, the Bible tends to describe sex/sex with multiple women as an amazing thing (Songs of Solomon) even if it's paid for. In a way it's always paid for, even from the beginning, a man had to buy his virgin wife from her parents.

Now think about our Nanny State and all the taboos of sex/talks of sex and how the government continually bemoans the lack of babies. We have essentially tabooed sex itself!

And if we never talk about it openly and talk to our children the responsibilities of this profound and amazing act, how will we as a society and as individuals ever achieve maturity in our thoughts and feelings regarding the issue? On a more personal note, I've noticed that a bout of amazing sex solves more arguments that cold facts and logical reasoning, it is therefore, a logical assumption that the nitty gritty of the course of marriage might run a little smoother with semi-regular exchanges of bodily fluids no?

Singapore Wars: A New Hope

April 27, 2009 AFP article

Workers protest against unpaid wages in Singapore

SINGAPORE - More than 100 construction workers from China gathered outside Singapore's manpower ministry Monday to complain about unpaid wages and cancellation of their work permits, witnesses said.

The workers sat for about two hours at the steps of the ministry, at a busy intersection near the Chinatown district, and shouted at ministry officials and police officers to air their grievances.

There was no violence, an AFP reporter at the scene said.

At one point, police warned the workers to disperse within five minutes or face arrest. They left but regrouped across a road from the ministry, and voluntarily dispersed about an hour later.

Workers interviewed by AFP said they had not been paid their wages after their Chinese 'boss' absconded with the money. They also complained that their work permits had been cancelled without warning.

Comment from the manpower ministry on the workers' complaints was not immediately available.

Some of the workers told officials that they had not committed any crime and could not be arrested, but police told them they were illegally trespassing on government property.

'The government should punish the company, not punish us by cancelling our permits. We just want our compensation so we can go back to China,' construction worker Zhou Qing Ren, 40, told AFP.

'We have got no money to eat now and no proper place to stay,' another worker shouted.

Singapore is tightening its rules on outdoor protests as it prepares to host its largest international summit, the Asia-Pacific Economic Cooperation (APEC) leaders' forum, in November.

Analysts said the laws against outdoor protests can also be applied to deal with any outbreaks of public frustration amid the city-state's worst recession in more than 40 years.

An estimated one million foreigners live in Singapore, representing more than 20 percent of the total population, which is predominantly ethnic Chinese.

This is a very important article. I believe the ruling party has managed to unearth a double edged sword.

Current foreign policy pursues a no-holds barred "Economic Growth at all costs"

A policy of: More inputs = more outputs = more GDP".

More inputs = More foreign talent willing to work at 1/2 the pay of a Singaporean.

Understandably so, hungry migrant workers can earn quadruple in Singapore what their home-bound brethren earn is a win-win solution for owners of these firms and their fledging immigrants.

But, it looks like the ruling party has failed to take into account the tenacity and devil-may-care attitude of these workers. And if these workers continue to run numbers into the 1 million (according to the AFP article), even 10% of the 1 million, conducting a protest of POOR LABOUR LAWS/TREATMENT during the APEC summit is going to be a PR disaster of massive proportions.

These migrant workers have little to lose, considering that they have lost it all already. They just want their money and they want to go home. When asked by the police to vacate the premises, they just regrouped opposite the Manpower Ministry.

What's the ruling party to do?

  • Put them in jail? - Woohoo! Free room and board.
  • Pay them? - Who bears the burden of paying?
  • Violent crackdown? - PR disaster also
Suddenly with 1 million migrants that don't give a damn about Home Upgrading, Jail, Defamation suits and threats of exile, the PAP might find in them- "considerable enemies of the State".

Fact is, if Singaporean dissidents/dissenters/opposition start to "embrace and love these foreign talent". They might very well mobilize this vocal and active group to campaign and highlight the fundamental flaws of poor protection/treatment of employees here in Singapore.

Can the PAP continue to treat all residents: citizens, permanent or otherwise, as "economic digits"? You decide.

The one thing Singapore does right

Political Correctness- It's a bane for the United States of America and the only advantage that Singapore has over the big bad "decadent" West.

Rob McKay for NZ Herald

Recently I was in Singapore. What really struck me were the low crime rates, genuine honesty and politeness of its citizens.

Singapore has zero tolerance for bad behaviour. They achieve this by being tough on those who break the rules. The phrase "political correctness" is nonexistent. You talk on your cellphone in the car: you lose the phone and $500. You eat on the train and there goes another $500. Drop a lolly paper on the ground and that will cost another $500 - all of this compliance and not a policeman in sight.

Singapore is full of novel ideas that make the city so safe and prosperous. The place is run like an efficient organisation. Why? Because Singapore has an over-riding policy of "zero tolerance for poor performance and bad behaviour".

We have become so PC in this country that people are too afraid to do anything for fear of repercussions. Managers are constantly accepting below average performance - why?

In many cases the manager has hired a person who does not "fit" the job, and they try to "fix" the problem by embarking on a treadmill of coaching and training, or a mixture of other "touchy feely" processes. Let me tell you straight up, if you have hired a person who does not have the innate personality, mental ability and attitude to do the job, no amount of training will make a silk purse out of a sow's ear. You might as well toss the training budget - and the six months of your time pandering to the situation - out the window.

Poor performance must be addressed immediately. The longer it's left, the worse it gets. Then one morning, you will wake up and decide enough is enough, go to the office and deal with it in an inappropriate manner that will probably cost you an expensive personal grievance claim.

Most organisations have three kinds of employees - have a look around your team now - you'll see people who were born to perform well (20%), some who have the capacity to perform well (60%) and those who will never perform (20%). Jack Welch, the famous American CEO, used to grade his team into As, Bs and Cs. The As were groomed for higher things. The Bs were trained to maintain, or fill the A slots and Cs were targeted to be managed out.

Often, managers take work off the Cs and lump it onto the As because they can be trusted to do quality work without a fuss. So the Cs are automatically rewarded for bad performance and usually get the same take-home pay. Here we see motivation working in the negative. There is motivation to perform badly because you get paid to do nothing.

It's time to get tough - "zero tolerance for poor performance" should be your new mantra. Don't allow the C team the luxury of passing off their responsibility to perform - set goals, introduce targets, measure output - ride hard, reward well.

Usually, when the pressure to perform comes on the C brigade, these slackers fold like a deck of cards and leave. But be very diligent when looking for a replacement: the next candidate could be the joker who was dealt off the deck of the last company because of poor performance.

As managers and leaders we have three opportunities to do something about our people performance. The first is at the front door - hire the right people first time - hire for attitude, train for aptitude.

The second opportunity is training and coaching your current people - ideal for your A and B people, but a huge waste of management time and money if you never got the first opportunity right. And finally, show the poor performers the back door - almost impossible to achieve in today's litigious employment environment.

Getting rid of poor performers is a long, morale-sapping, customer-killing, bank-balance-denting process. You have to face up to the fact, fast, that you screwed up and hired poorly. Many times this situation is not the employee's problem; they simply didn't "fit" the position and you never identified this.

"People" are the only lasting competitive advantage your business has, so here's another mantra - hire tough and manage easy.

Societal Mental Conditioning


More to come once I gather my thoughts- Happy Easter weekend.

Schizophrenia sufferers aren't fooled by an optical illusion known as the “hollow mask” that the rest of us fall for because connections between the sensory and conceptual areas of their brains might be on the fritz.

In the hollow mask illusion, viewers perceive a concave face (like the back side of a hollow mask) as a normal convex face. The illusion exploits our brain's strategy for making sense of the visual world: uniting what it actually sees — known as bottom-up processing — with what it expects to see based on prior experience — known as top-down processing.

"Our top-down processing holds memories, like stock models," explains Danai Dima of Hannover Medical University, in Germany, co-author of a study in NeuroImage. "All the models in our head have a face coming out, so whenever we see a face, of course if has to come out."

This powerful expectation overrides visual cues, like shadows and depth information, that indicate anything to the contrary.

But patients with schizophrenia are undeterred by implausibility: They see the hollow face for what it is. About seven out of 1000 Americans suffer from the disease, which is characterized by hallucinations, delusions, and poor planning. Some psychologists believe this dissociation from reality may result from an imbalance between bottom-up and top-down processing — a hypothesis ripe for testing using the hollow mask illusion.

In healthy viewers, the illusion is so powerful that even when aware of the illusion (see video below), they are unable to see the concave face — the mind just flips it back. Though the illusion is strong for faces, it doesn't work well with other objects, or even with upside-down faces. This bias is likely due to the special relationship we humans have with faces. Many neuroscientists believe we have brain regions dedicated to processing faces, and some brain injuries can leave patients unable to recognize faces, even though their vision and other memories remain intact.

Dima and Jonathan Roiser of University College London wanted to understand why people with schizophrenia aren't fooled. They put 13 schizophrenia patients and 16 healthy control subjects in an fMRI scanner that measures brain activity, and showed them 3D images of concave or convex faces. As expected, all of the schizophrenic patients reported seeing the concave faces, while none of the control subjects did.

Dima and Roiser analyzed the fMRI data using a relatively new technique called dynamic causal modeling, which allowed them to measure how different brain regions were interacting during the task. When healthy subjects looked at the concave faces, connections strengthened between the frontoparietal network, which is involved in top-down processing, and the visual areas of the brain that receive information from the eyes. In patients with schizophrenia, no such strengthening occurred.

Dima thinks when healthy subjects see the illusion, which is somewhat ambiguous, their brains strengthen this connection such that what they expect — a normal face — becomes more influential, overpowering the actual, though unlikely, visual information. Schizophrenia patients, meanwhile, may be unable to modulate this pathway, accepting the concave face as reality.

Schizophrenics aren't the only ones who see the concave face — people who are drunk or high can also 'beat' the illusion. A similar disconnect between what the brain sees and what it expects to see may be occurring during these drug-induced states.

Marijuana: The possible solution to aid the economy

John Gilliam for the Huffington Post:

Today, in the historic first online town hall, President Obama fielded questions from nearly a hundred thousand people online. One of the most popular questions, and indeed, one of the most popular questions in any forum that lets people vote on what matters to them, was about whether legalizing marijuana would help improve the economy and job creation.

Chuckling, the President said: "I don't know what this says about the online audience, but [laughing] this was a fairly popular question, we want to make sure it was answered. The answer is no, I don't think that is a good strategy to grow our economy."

Truth, Justice and the non-PAP way

Singapore again ousts the editor of the Asia Sentinel
You can say one thing for Singaporeans. They have long memories. And if you think the place is loosening up, think again.In 1988 — 21 years ago — my projected three-year stint as the Asian Wall Street Journal's correspondent in Singapore ended two years early when the Singaporeans refused to grant me another work visa, and I was forced to leave the island republic to its own devices. Singapore does not now take kindly to the practice of independent journalism, and it didn't then. The media watchdog organization Reporters Without Borders ranks Singapore 140th out of 167 countries surveyed in terms of freedom of the press. The country has been kicking foreign journalists out for writing critical articles about the republic since the early 1970s.
Fast forward through three jobs and several countries to March 17, 2009 – Tuesday – when I flew to Singapore for a one-day stopover as a formality to getting a new visa for Indonesia. The bullfrog-faced woman at the country's immigration counter, an office that is among the world's fastest and most efficient – stiffened visibly when she entered my US passport into her computer, and immediately called for backup. Twenty-one years later, I was being bounced out of the country again.  The Burmese general Thein Sein was luckier. The junta member got a warm welcome and an orchid named for him. Perhaps there was a mixup, or perhaps he banks there. Seconds after the woman passed my passport through her scanner, I was shepherded away from the usual scrum of passengers headed out into Singapore's tropical sunlight, and into a facility where a stone-faced immigration officer apparently busied himself making telephone calls. When I attempted to ask to inform a colleague on the same trip that I had been detained, he shooed me back into the facility, where I sat watching a couple of football teams contend for a half hour or so.After what appeared to be a series of telephone calls to bureaucrats somewhere, ultimately, I was led away and into the upper reaches of Changi Airport. 

Changi is a great airport, with an array of stores that would cause envy to some of the world's best department stores. But there are parts of Changi that you probably aren't ever going to see. One of those parts was a barren room with a quote on the wall from J.M. Barrie, who created Peter Pan, that "it is more important to like what you do than to do what you like." It was equipped with a couple of racks of bunk beds and two television sets, where I sat with a half-dozen Chinese hookers who watched a Martha Stewart cooking show with considerable interest, considering that none of them spoke English.An couple of hours later, a wholly polite and accommodating immigration officer acceded to my request and paroled my passport from other officials so that I could go to duty-free and liberate a couple of bottles of gin to take back to nominally dry Jakarta. He showed the passport to the duty-free lady to endorse the purchase, then took the passport back. Finally I was herded to seat 64D on SQ958 – the very last row. I wasn't to get my passport back until SIA officials escorted me to Indonesian immigration, where I, my passport and my duty-free liquor were liberated.
