COINCIDENCE is not generally something scientists have much truck with. If two things are genuinely unrelated, there is little further of interest to be said. If the coincidence keeps turning up, however, there must be some deeper underlying link. Then it is the job of science to tease out what it is and so explain why there was no coincidence in the first place.
That makes it rather odd that a large chunk of modern physics is precariously balanced on a whopping coincidence.
This coincidence is essential to the way we view and define mass. It is so fundamental to the world's workings that most of us encounter its consequences every day without giving them another thought. Yet it has vexed some of the best minds in physics for centuries. Galileo and Newton grappled with it, and ended up just accepting it, rather than understanding it. Einstein went one better: ...

SEOUL : Taxi drivers in South Korea are threatening to go on a partial strike from January 30.
It is in protest against a government decision to block legislation that would give them subsidies for public transport.
The so-called "Taxi Bill" was passed in Parliament earlier this month, but was vetoed by President Lee Myung-bak and will go back to Parliament for another vote.
If Parliament fails to pass the bill, all taxis across the country will go on strike from February 20.
The question being asked in South Korea is whether taxis should be considered public transportation, the same way that buses, subways and trains are.
Most lawmakers in Parliament have said "yes", but President Lee's government disagrees.
Yim Jong Yong, Minister in the Prime Minister's Office, said: "Public transportation refers to mass transportation, operating along specific routes and fixed timetables, so taxis cannot be included in this category."
The taxi bill was passed in Parliament earlier this month, with overwhelming support from both the ruling and opposition parties.
Classifying taxis as part of the country's mass transportation system means they can get state subsidies on fuel, tax and other benefits, just like bus and subway operators do.
Reports say central and local governments spend about 1.2 trillion won - or about US$1.1 billion - subsidising the bus industry every year.
If taxis are included, critics say the government would have to more than double its spending on subsidies, costing it an additional 1.9 trillion won a year.
They point out that taxis account for only about 9 per cent of transportation, whereas buses make up over 30 per cent.
Subways and trains account for more than 20 per cent.
But taxi drivers argue that they should be considered part of the public transport system.
Koo Soo Young, head of the Taxi Drivers Union, said: "There is a reason why taxis should be classified as public transport. Buses carry about 13 million passengers in one day, while taxis carry about 11 million passengers. Also the number of trains and subways is only about half the number of taxis. This shows that a large number of people use taxis because the fares are so cheap."
Although the government has rejected the bill, it said it is willing to help the taxi industry.
It is planning to come up with a plan that would give some subsidies to taxi drivers and at the same time appease bus drivers, who worry they will have to share government subsidies with taxis.
Taxi drivers are threatening to go on strike over this bill. But experts have pointed out that subsidies in the Taxi Bill will likely only benefit taxi companies, and not the drivers themselves. So drivers will really need to think this through and see what the government has to offer first.
Britain's Prince Harry says he killed Taliban militants during tour in Afghanistan
Harry, known to comrades as Captain Wales, had served for four months in Helmand province
Harry: "We fire when we have to but we're more of a deterrent than anything else"
(CNN) -- Britain's Prince Harry has acknowledged that he killed Taliban insurgents on his latest tour of duty in Afghanistan as a crew member of an Apache attack helicopter.
Harry has been serving for four months as a co-pilot gunner (CPG) in southern Helmand province -- considered a Taliban heartland -- and flew on scores of missions with the trigger to rockets, missiles and a 30mm cannon at his fingertips.
No one is saying how many insurgents Harry might have killed but toward the end of his deployment, the 28-year-old, known to his comrades as Captain Wales, shared some of his feelings about combat with reporters while on duty in the massive military base known as Camp Bastion. He said it was sometimes justified to "take a life to save a life. That's what we revolve around, I suppose."

Harry explained how the roles of Apaches and CPGs have changed since his previous deployments in 2007 and 2008. "It used to be very much: front seat, you're firing the whole time.
"Now, yes we fire when we have to but essentially we're more of a deterrent than anything else.
"Our job out here is to make sure the guys are safe on the ground and if that means shooting someone who is shooting at them, then we will do it," said the prince, third in line to the British throne.
"It's not the reason I decided to do this job. The reason to do this job was to get back out here, and carry on with a job."
Away from his helicopter, the prince mixed freely on base, eating in the canteen with everyone else and relaxing by playing video games with others in the 130-strong 662 Squadron, 3 Regiment Army Air Corps (AAC). With those comrades, he was just "one of the guys."

In contrast to his privileged upbringing in palaces and an education at Eton College, the prince lived in a shared room within shipping containers converted into an accommodation block. He said he was free to stroll around the base, to visit the gym or the laundry. "It's completely normal," Harry added.
But he said he still received unwanted attention in more public places. "For me it's not that normal because I go into the cookhouse and everyone has a good old gawp, and that's one thing that I dislike about being here," he said.
Opinion: Cheeky Harry vs. dull brother William
"Because there's plenty of guys in there that have never met me, therefore look at me as Prince Harry and not as Captain Wales, which is frustrating.
"Which is probably another reason why I'd love to be out in the PBs (patrol bases), away from it all.
"But yeah, it's completely normal. It's as normal as it's going to get. I'm one of the guys. I don't get treated any differently."
His deployment meant he could step back from the public eye, although he said his father, the heir to the British throne Prince Charles, often reminded him of his position. Harry admitted he had "let himself and his family down" when he was photographed naked at a party in a Las Vegas hotel last year.

He also expressed frustration about the media. Referring to the TV producer whom he was addressing, he said: "I never wanted you guys to be out here, but there was an agreement made to invite you out on the deal that the media didn't speculate before my deployment. That's the only reason you guys are out here."
Harry appeared happier talking about his military role: building up the Afghan National Army, the ANA, so it can eventually take over.
"It's great to see the ANA taking more of a lead in things as well. And the professionalism is definitely shining through."
That's something his superiors in the army might say of the prince himself.

President Obama is a student of history - it was no coincidence that he formally announced his run to become the first African-American president back in 2007 at the Old State Capitol in Springfield, Illinois, where Abraham Lincoln delivered his "house divided" speech in 1858 - and his inaugural address today drew an unmistakable line between the nation's past and its prospects for the future.

President Obama's second inaugural speech
The president opened his remarks by referencing Lincoln's words from that speech, stating that America came to realize at that point in history that "no union founded on the principles of liberty and equality could survive half-slave and half-free." He grounded his remarks in the Declaration of Independence's claim that "all men are created equal," tying it to both the American Revolution and rules mandating that there is fair play in the free market, to the need for a great nation to "protect its people from life's worst hazards and misfortune."
Later, he again invoked the declaration - though this time, he referred to the notion that "all of us are created equal" - before referencing three landmark moments in the battle for civil rights: The Seneca Falls Convention for women's rights, the clashes in Selma for African-American rights and the riots at New York's Stonewall Inn for gay rights. (The speech marked the first presidential inaugural in which LGBT rights have been referenced.)
He then pivoted from the triumphs of the past to the necessity of continuing the fight, calling for equal pay for women, equal rights for gay men and women, an elimination of long lines to vote, better treatment of immigrants, and, in an indirect reference to his desire to pass gun control legislation, the necessity of children from Detroit to Appalachia to Newtown to know "that they are cared for, and cherished, and always safe from harm."

Brinkley on inaugural address: "A great civil rights speech"
At five separate moments in his second inaugural address, delivered to an estimated 500,000 to 700,000 people at the Capitol, Mr. Obama uttered the words "We, the people" - the opening words to the preamble of the Constitution. Those words were deployed to underscore the president's argument that Americans need to recognize that we are all in it together - and that while America celebrates initiative and enterprise, "preserving our individual freedoms ultimately requires collective action."
"For the American people can no more meet the demands of today's world by acting alone than American soldiers could have met the forces of fascism or communism with muskets and militias," he said. "No single person can train all the math and science teachers we'll need to equip our children for the future, or build the roads and networks and research labs that will bring new jobs and businesses to our shores. Now, more than ever, we must do these things together, as one nation, and one people." He went on to add that "we are made for this moment, and we will seize it - so long as we seize it together."
That idea underscored the positions Mr. Obama reiterated during the speech, which at times came closer to a policy-oriented State of the Union Address than an inaugural, which historically tends to be more about soaring rhetoric. (The president will offer his State of the Union on February 12.) In addition to arguing that economic inequality hampers the nation's success, he said that the future depends on harnessing "new ideas and technology to remake our government, revamp our tax code, reform our schools, and empower our citizens with the skills they need to work harder, learn more, and reach higher."
"We do not believe that in this country, freedom is reserved for the lucky, or happiness for the few," said the president. "We recognize that no matter how responsibly we live our lives, any one of us, at any time, may face a job loss, or a sudden illness, or a home swept away in a terrible storm. The commitments we make to each other - through Medicare, and Medicaid, and Social Security - these things do not sap our initiative; they strengthen us. They do not make us a nation of takers; they free us to take the risks that make this country great."
Mr. Obama also fit a call for a renewed focus on fighting climate change - an issue largely absent from his first-term agenda - into the notion of collective action for the common good, saying that "the failure to [address it] would betray our children and future generations."

Axelrod on Obama's vision for economy
In addition to climate change, Mr. Obama's second term agenda involves pushing passage of gun control and immigration legislation, overseeing the further implementation of the health care law, winding down the war in Afghanistan, and continuing to try to find some way to come to a major agreement with Republicans to address the nation's massive debt and deficit.
He has signaled that to accomplish these goals, he will take a more confrontational approach with Republicans than he did in his first term -- an approach illustrated by his recent refusal to negotiate on raising the debt limit. His inaugural address offered little in the way of appeals for Washington bipartisanship; instead, Mr. Obama called on Americans in and out of the nation's capitol to come together to help the nation stay on the right path, even if the results are sometimes "imperfect."
"Progress does not compel us to settle centuries-long debates about the role of government for all time - but it does require us to act in our time," he said. "For now decisions are upon us, and we cannot afford delay."
It was an appeal grounded in the notion that America's strength comes from all its citizens, no matter their status. And it was offered by a president who knows the debt he owes to history - a president who sees himself both as a symbol of American progress and a vessel to keep it moving forward.
A presidential inauguration is a big, long event that lasts all day and into the night–and who has time to really watch it? People have jobs, ones that don’t let you off for a federal holiday.
Everyone (or, at least, some) will be talking about it, which means potential embarrassment for anyone who doesn’t know what happened. Thankfully, ABC employs news professionals stationed in Washington, D.C., to pay attention to these kinds of things and boil off some of the less noteworthy or interesting stuff, presenting you with short videos of everything that really mattered. Or at least the things a lot of people were talking about.
A full day of paying attention to President Obama’s second Inauguration leads one of those professionals to offer these 7 1/2 things:
1. Beyonce Sang the National Anthem
Boy, howdy! Did she ever? Beyonce has essentially become the Obama’s go-to female performer: She recorded a music video for Michelle Obama’s “Let’s Move” initiative in 2011, and she performed at the president’s last inauguration in 2009. Her velvety, soulful “Star Spangled Banner” is getting good reviews.
2. Kelly Clarkson Also Sang
Kelly Clarkson is not as “in” with the First Couple as Beyonce seems to be, but they let her sing “My Country ‘Tis of Thee,” and she did a pretty good job with it. This was kind of weird, though, because at one point she said she loved Ron Paul, although she later said she would vote for Obama.
3. Obama Talked About Gay Rights
This may not seem shocking since more than half the country, including President Obama, supports gay marriage. But the president made a point of mentioning gay rights during his speech, equating the struggles of the LGBT community with those of past civil rights movements, and in doing so made history.
He name-checked Stonewall, the New York City bar that was raided by police in 1969 sparking riots to protest the anti-gay crackdown. And he actually used the word “gay”: “Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law – for if we are truly created equal, then surely the love we commit to one another must be equal as well,” Obama said in his address.
Plenty of inaugural addresses have been chock full of rhetoric about freedom and equality, but in the last four years, the political culture surrounding gay rights has changed significantly, as more states legalized same-sex marriage and as broad swaths of the country got more comfortable with homosexuality in general. Obama’s “evolution” on gay marriage, and now his inaugural address, have helped signify that change.
4. Joe Biden Made Jokes and Shook Hands With People
Could we expect anything less?
Here’s how the Vice President toasting Sen. Chuck Schumer instead of President Obama at the big luncheon: ”I raise my glass to a man who never, never, never operates out of fear, only operates out of confidence, and a guy–I’m toasting you, Chuck.” Watch it:
And here he is, scurrying around and jovially shaking hands with people along the parade route:
5. Richard Blanco Read a Poem That Was Sort of Whitman-esque, But Not Entirely
Cuban-born Richard Blanco became America’s first openly gay, Latino Inauguration poet. He read a nine-stanza poem entitled “One Today,” which set a kind of unifying American tableau scene.
6. Obama and Michelle Walked Around Outside The Limo
President Obama walked part of the parade route, from the Capitol to the White House, with Michelle. They waved to people. It is not entirely abnormal for a president to do this at an inaugural parade. But they walked quite a ways.
7. John Boehner: ‘Godspeed’
The speaker of the House presented American flags to Obama and Biden, telling them: “To you gentlemen, I say congratulations and Godspeed.”
7 1/2. Sasha and Malia Were There.
Obama’s daughters, Sasha and Malia, were there. They didn’t really do much, but they did wear coats of different shades of purple that got a lot of attention on Twitter.
Reports of the daughters looking at smartphones and applying lip gloss highlighted their day. As did this .gif of Sasha yawning.
SINGAPORE: From 1 May 2013, working fathers will be legally entitled to one week of paid paternity leave.
Parents welcome the move, but some pro-family organisations are calling for bolder measures.
Eileen Chan and Alvin Tan tied the knot two years ago. They are expecting their firstborn in April, and with that, the bumped-up Baby Bonus.
"I think the extra S$2,000 will come in handy, especially when it comes to immunisation for the kid," said Ms Chan. "In the first year, kids tend to fall sick more often."
For the Tans, the most welcome new measure is paternity leave. Mr Tan plans to take the week off right after his wife delivers.
He said: "Especially when the baby is new-born, as a father I'd like to spend more time at home with the kid, with my wife to help settle the kid in."
Alvin is optimistic his employer will grant his paternity leave, even though his child will be born just before the measure officially kicks in on 1 May 2013.
Employers are encouraged to offer paternity leave to all eligible employees with children born on or after 1 Jan 2013, and this will be reimbursable by the government.
Ms Chan can also share one week of her maternity leave with her husband.
It's a move the National Family Council welcomes, but its chairman Mr Lim Soon Hock is calling for a whole month of maternity leave to be made gender-neutral.
Mr Lim said: "If we were to have longer paternity leave, essentially what we are creating is an opportunity for our women to go back to work earlier. But fundamental to this thinking must be that we have to move away from the notion that men are more valuable in the workplace than women."
The slew of bonuses is good news, but it is not the reason why the Tans want to have two children.
Mr Tan said: "The baby itself is the bonus, so all these incentives, we're just happy to receive them!"
The new Marriage and Parenthood Package also makes adoption leave a legal entitlement.
Working, married women who adopt children under a year old will be entitled to four weeks of government-paid leave.
Previously, this was offered by employers on a voluntary basis.
Frostbite can occur in as little as 10 minutes in extreme wind chill, the CDC warns
Monday's highs in North Dakota and Minnesota will stay below zero
Extreme cold is dangerous to people with heart conditions
(CNN) -- Frigid temperatures in Minnesota and North Dakota this week will have residents thinking they've been living in the tropics all season.
Nighttime temperatures plummeted to 2 degrees Fahrenheit on Saturday night.
As if that's not enough, they will take another dive early Monday, this time to minus 28.
The National Weather Service warned that strong winds would dunk the mercury in the upper plains states and plunge wind chill factors to as low as minus 50 degrees Fahrenheit.
High temperatures Monday are predicted to stay below zero.
The Centers for Disease Control warns people in extremely cold areas to stay in heated rooms and keep outdoor trips brief.
At 30 below zero, frostbite can occur in as little as 10 minutes with the slightest winds, and in five minutes in a brisk breeze, the CDC warns. Newborns, the elderly and the homeless can quickly fall victim to hypothermia.
"Cold weather puts an extra strain on the heart," the CDC said, and overexertion can become even more dangerous to those with heart conditions in the Arctic cold.
Although such deep freezes are potentially deadly, they are not uncommon in the upper midsection of the United States. The North Dakota Department of Emergency Services said it did not deploy additional staffing because of the weather.

King, Civil Rights Act remembered
Yet today, 50 years after King shared this vision during his most famous speech, there is considerable disagreement over what it means.
The quote is used to support opposing views on politics, affirmative action and programs intended to help the disadvantaged. Just as the words of the nation's founders are parsed for modern meanings on guns and abortion, so are King's words used in debates over the proper place of race in America.
As we mark the King holiday, what might he ask of us in a time when both the president and a disproportionate number of people in poverty are black? Would King have wanted us to completely ignore race in a "color-blind" society? To consider race as one of many factors about a person? And how do we discern character?
For at least two of King's children, the future envisioned by the father has yet to arrive.
"I don't think we can ignore race," says Martin Luther King III.
"What my father is asking is to create the climate where every American can realize his or her dreams," he says. "Now what does that mean when you have 50 million people living in poverty?"
Bernice King doubts her father would seek to ignore differences.
"When he talked about the beloved community, he talked about everyone bringing their gifts, their talents, their cultural experiences," she says. "We live in a society where we may have differences, of course, but we learn to celebrate these differences."
The meaning of King's monumental quote is more complex today than in 1963 because "the unconscious signals have changed," says the historian Taylor Branch, author of the acclaimed trilogy "America in the King Years."
Fifty years ago, bigotry was widely accepted. Today, Branch says, even though prejudice is widely denounced, many people unconsciously pre-judge others.
"Unfortunately race in American history has been one area in which Americans kid themselves and pretend to be fair-minded when they really are not," says Branch, whose new book is "The King Years: Historic Moments in the Civil Rights Movement."
Branch believes that today, King would ask people of all backgrounds - not just whites - to deepen their patriotism by leaving their comfort zones, reaching across barriers and learning about different people.
"To remember that we all have to stretch ourselves to build the ties that bind a democracy, which really is the source of our strength," Branch says.
Bernice King says her father is asking us "to get to a place - we're obviously not there - but to get to a place where the first thing that we utilize as a measurement is not someone's external designation, but it really is trying to look beyond that into the substance of a person in making certain decisions, to rid ourselves of those kinds of prejudices and biases that we often bring to decisions that we make."
That takes a lot of "psychological work," she says, adding, "He's really challenging us."
For many conservatives, the modern meaning of King's quote is clear: Special consideration for one racial or ethnic group is a violation of the dream.
The quote is like the Declaration of Independence, says Roger Clegg, president of the Center for Equal Opportunity, a conservative think tank that studies race and ethnicity. In years past, he says, America may have needed to grow into the words, but today they must be obeyed to the letter.
"The Declaration of Independence says all men are created equal," Clegg says. "Nobody thinks it doesn't really mean what it says because Thomas Jefferson owned slaves. King gave a brilliant and moving quotation, and I think it says we should not be treating people differently on the basis of skin color."
Many others agree. King's quote has become a staple of conservative belief that "judged by the color of their skin" includes things such as unique appeals to certain voter groups, reserving government contracts for Hispanic-owned businesses, seeking more non-white corporate executives, or admitting black students to college with lower test scores.
In the latest issue of the Weekly Standard magazine, the quote appears in the lead of a book review titled "The Price Was High: Affirmative Action and the Betrayal of a Colorblind Society."
Considering race as a factor in affirmative action keeps the wounds of slavery and Jim Crow "sore and festering. It encourages beneficiaries to rely on ethnicity rather than self-improvement to get ahead," wrote the author, George Leef.
Last week, the RightWingNews.com blog included "The idea that everyone should be judged by the content of their character, not the color of their skin" in a list of "25 People, Places and Things Liberals Love to Hate."
"Conservatives feel they have embraced that quote completely. They are the embodiment of that quote but get no credit for doing it," says the author of the article, John Hawkins. "Liberals like the idea of the quote because it's the most famous thing Martin Luther King said, but they left the principles behind the quote behind a long time ago."
President Obama used the first public remarks of his second term to address what he called the “most significant” event of this weekend: his wife’s much-talked-about new haircut.
“I love her bangs,” Obama told supporters at an inaugural reception at the National Building Museum. “She looks good. She always looks good.”
First lady Michelle Obama, wearing a black sequined cocktail dress and showcasing her new hairdo, also heaped compliments on her husband.
“Let me tell you, it has just been a true thrill to watch this handsome, charming individual grow into the man and the president that he is,” she said, as she reached out to playfully touch the president’s face, sparking laughter from the crowd.
Praising his compassion and courage, the first lady introduced the president as the “love of her life.”
Obama, who was sworn in for a second term in a small White House ceremony earlier today, kept his remarks short, noting he has another big speech to deliver Monday.
“There are a limited amount of good lines and you don’t want to use them all up tonight,” he joked.
Because the Constitutionally mandated date for the inauguration, Jan. 20, fell on a Sunday this year, the traditional, public ceremony was delayed until Monday.
Saving the best for his official inaugural address, the president instead dedicated the bulk of his remarks to thanking supporters for their hard work and dedication to getting him re-elected.
“You understood this was not just about a candidate; it was not just about Joe Biden or Barack Obama. This was about us, who we are as a nation, what values we cherish, how hard we’re willing to fight to make sure that those values live not just for today but for future generations,” he said.
“All of you here understood and were committed to the basic notion that when we put our shoulders to the wheel of history, it moves… It moves forward. And that’s part of what we celebrate when we come together for inauguration,” he said.
