Police: Bomber kills 1 in Somali hospital attack
MOGADISHU, Somalia (AP) ? A bomber detonated a minivan laden with explosives outside a Turkish hospital in Somalia's capital on Saturday, killing at least one person and wounding more than three others, a Somali police officer said.
The bomber also died in the attack at the Al-Shifa hospital in Mogadishu, said Mohammed Abdi.
Al-Shabab insurgents claimed responsibility for the attack on Twitter saying they were targeting a group of Turkish diplomats. The group said the operation was not a suicide attack and that those who carried out the attack had safely gone back to their bases.
Al-Shabab, which has links with al-Qaida, has been carrying out guerrilla attacks in Somalia since the group was expelled from the capital by African Union troops in August 2011. It has long been threatening Turkish workers and aid agencies in Somalia accusing them of spreading secularism in Somalia.
"The Turkish are part of a group of nations bolstering the apostate regime and attempting to suppress the establishment of Islamic Shari'ah," al-Shabab said on Twitter.
The expulsion of al-Shabab in the capital ended years of daily violence that had caused the rest of the world to shun the capital for two decades. After the ouster of al-Shabab the international community started trickling back into Mogadishu, and the United Nations began moving its personnel to Somalia from Kenya.
But al-Shabab still holds sway in some parts of rural southern Somalia and retains the ability to stage lethal attacks even in Mogadishu. Last month militants on a suicide mission invaded the U.N. compound in Mogadishu with a truck bomb and then poured inside, killing at least 13 people before dying in the assault.
Earlier this month a bomb exploded inside the largest market in the Somali capital, wounding at least five government soldiers aboard a military vehicle.
The bomb was concealed inside a Somali military pick-up truck in Mogadishu's sprawling Bakara market, Mogadishu police official Mohamed Hussein said.
The United Nations envoy in Somalia condemned the attack. Nicholas Kay, head of the U.N. Assistance Mission in Somalia that began operations last month, offered his condolences to the Turkish government, victims and their families.
"Turkey has been working tirelessly and bravely to help the Somali people over the last few years," he said in a statement.
The U.S. State Department made a similar statement.
"This cowardly act will not shake our commitment to continue working for the brighter, more democratic and prosperous future the people of Somalia deserve," spokeswoman Jen Psaki said.

Obama: House GOP budget is 'bad bargain'
Click photo to enlarge
JACKSONVILLE, Fla.?Casting House Republicans as stubborn deadbeats, President Barack Obama sought Thursday to discredit House Republicans in upcoming fiscal fights by painting them as roadblocks to a thriving middle class.
President Barack Obama, center, gets a tour of the Jacksonville, Fla. port with, from left, Transportation Secretary Anthony Foxx; Dennis Kelly, TracPac Regional Vice President and General Manager; Ray Schleicher, CEO of the Jacksonville Port Authority, and Fred Wakefield, International Longshoreman's Association Representative, during a tour, Thursday, July 25, 2013. A day after he kicked off the tour in Illinois and Missouri, Obama was traveling Thursday to a seaport in Jacksonville, Fla., to yet again deride the wide gulf between his vision for a new American prosperity driven by a burgeoning middle class and the intense gridlock snarling up Congress.
JACKSONVILLE, Fla.?Casting House Republicans as stubborn deadbeats, President Barack Obama sought Thursday to discredit House Republicans in upcoming fiscal fights by painting them as roadblocks to a thriving middle class. With Obama and Congress approaching all-too-familiar showdowns over spending levels and the nation's borrowing limit, Obama used a visit to a seaside port in Florida to argue that the nation's economic agenda should be immune to the partisan backbiting he faulted Republicans for instigating.
"Shutting down the government just because I'm for keeping it open?that's not an economic plan," Obama said, wiping sweat from his face in a muggy port warehouse. "Threatening that you won't pay the bills in this country, when we've already racked up those bills, that's not an economic plan?that's just being a deadbeat."
In the last of three stops on a two-day tour to reframe his broad economic vision for the nation, Obama pitched the need for enhanced American infrastructure at this port and others across the country?and for better roads, bridges and power grids. But while he touted his efforts to streamline permitting, the president offered no new proposals for how Americans and their leaders could accelerate a lethargic economic recovery.
Obama warned that if Republicans continue with their "my way or the highway attitude," dire consequences could await for Americans. He encouraged voters to use next month's congressional recess to tell Republicans who'll be in their home districts that gridlock is unacceptable. "It could plunge us back into financial crisis," the president said.
Senate Minority Leader Mitch McConnell, R-Ky., questioned the point of Obama's big push in a speech on the Senate floor Thursday. "At some point, campaign season has to end and the working-with-others season has to begin," McConnell said. "At some point, you have to stop promising an 'ocean of tomorrows' and start actually working with the representatives of the people."
Obama praised Senate Republicans for being willing to compromise on issues like immigration, then drew a distinction with House Republicans, whom he repeatedly accused of bringing the economy to the brink. But Obama, too, at times has taken an uncompromising approach with ultimatums that force his opponents to give in or no deal. He's refused to consider any budget that includes the across-the-board, automatic spending cuts known as the sequester that went into effect in March.
The 2011 battle between Obama and House Republicans over raising the government's borrowing limit brought the nation close to default and resulted in a hard-fought budget deal. Obama says he won't be bullied on the debt ceiling again, but many in Washington believe the need to increase the borrowing cap later this year will prompt some kind of budget bargain.
A new poll by the Pew Research Center shows that pessimism about the economy remains widespread. The poll conducted last week found that 82 percent of Americans think the economy is in fair or poor condition and 67 percent are dissatisfied with the way things are going in the U.S. today. Forty-four percent think it will be a long time before the nation's economy recovers, while only 28 percent say it's currently recovering. The poll had a margin of error of plus or minus 3 percentage points.
Even among Democrats, just 38 percent think the economy is recovering. But there are signs of slow improvement: The housing market is recovering, the stock market is booming, and unemployment is falling despite remaining uncomfortably high at 7.6 percent.
After a examining the port's giant cranes used to lift shipping containers onto ships, Obama spoke to a few hundred workers in the sweltering warehouse. He lamented that the U.S. was lagging behind China and Germany on fixing infrastructure and said that's why he's working to speed up the federal permitting process.
"The businesses of tomorrow are not going to locate near outdated roads and old ports," he said. Improvements to the port so more supertankers can come in would mean more workers spending more money at restaurants so that the waitress serving them, for example, can spend more money on an iPod, he said.
In making his plea for more spending on public works projects, the president is also relying on support from corporate leaders whose businesses either benefit from government financed construction or rely on up-to-date transportation systems to move their products. The U.S. Chamber of Commerce has been pressing Congress for greater spending on infrastructure and has allied itself with the president's effort, but in a statement Wednesday, chamber President Thomas Donohue also put some distance with Obama by saying such a public works initiative must be tied to less regulation, lower taxes and less overall government spending.
"The president correctly underscored the importance of infrastructure, education and immigration to our economic future," Donohue said. "But in order to grow and create lasting private sector jobs, we must have more economic freedom and while reining in government spending, taxes and debt."
The visit also marked Obama's first to the state since the acquittal of George Zimmerman, the man charged in the death of Florida teenager Trayvon Martin. The case has generated a painful, nationwide debate about racial prejudice, but Obama didn't mention the case in his public remarks.
The broad economic themes Obama illustrated Thursday will be followed up in the coming weeks by another series of speeches drilling down on key sectors such as manufacturing, education, housing, retirement security and health care. Advisers say some of those speeches will contain more specific policy proposals, both for legislation and executive action Obama can take without congressional approval.
The first of those addresses was to come Tuesday, when Obama will travel to Chattanooga, Tenn., to promote American competitiveness at an Amazon fulfillment center, which packs and ships products to online purchasers. The White House said some new policy ideas will be unveiled during that visit.

China's Bo Xilai indicted for corruption, abuse of power
BEIJING: China's once high-flying communist politician Bo Xilai has been indicted for bribery and abuse of power, state media said Thursday, following a scandal that exposed deep divisions at the highest levels of government.
The former party chief of the southwestern city of Chongqing has not been seen in public for more than a year since the controversy surrounding him was exposed, triggering one of China's biggest political scandals in decades.
"The indictment paper was delivered" to a court in Jinan in the eastern province of Shandong, Xinhua said, citing prosecutors in the city.
Bo "took the advantage of his position to seek profits for others and accepted an 'extremely large amount' of money and properties," it said, quoting the indictment.
State media reports had said he would "face justice" for abuse of power, taking bribes and improper sexual relations following his wife Gu Kailai's conviction for murdering a British business associate.
A source with direct knowledge of the case, who requested anonymity, said the trial might begin in mid-August.
News of the proceedings comes at a time when the party's new leadership is trying to show it is cracking down on corruption and government waste.
The downfall of Bo, once one of 25 members of the Politburo of China's ruling Communist Party, exposed corruption allegations and deep divisions at the highest levels of government.
The scandal emerged last year ahead of a once-a-decade leadership transition, in which Bo had been considered a candidate for the Politburo Standing Committee, which currently has seven members and is China's most powerful body.
His downfall was triggered after his police chief and right-hand man Wang Lijun fled to a US consulate in Chengdu city near Chongqing, reportedly seeking asylum. Bo was detained a month later.
He had cultivated an unusually populist public image and led a high profile anti-mafia campaign, which resulted in scores of arrests but led to allegations of torture against suspects.
Bo also revived some elements of 1960s Communist Party culture as part of a "Sing Red" campaign involving massive rallies, which drew comparisons with China's tumultuous Cultural Revolution period.
His attention-drawing approach was controversial among the top communist leadership, but the decision to oust him would have required tough backroom negotiations among the country's top leaders ahead of the power handover, analysts have said.
Bo's wife was given a suspended death sentence last August for fatally poisoning businessman and family friend Neil Heywood. The penalty is normally commuted to a life sentence in China.
Wang was sentenced to 15 years in prison in September for defection and other crimes.
Official media said last year Bo had "borne major responsibility" for the murder of Heywood and had taken "massive" bribes and had indulged in inappropriate sexual relations with "multiple women".
Bo has appointed two lawyers for the trial, both of whom are members of a law firm which has close ties to the ruling party.
His fate has generated widespread speculation, and rumours in January that his trial would open in the southwestern city of Guiyang sent packs of reporters to what turned out to be a quiet courthouse.
The last former Politburo member to be tried for corruption, Chen Liangyu, received an 18-year prison term in 2008.

Sonos can now stream music stored on Android phones, tablets
Sonos speakers now play much nicer with Android. On Tuesday, Sonos updated its Android Controller app to give users the ability to play music stored on phones and tablets running Google's operating system. Previously, the Android Controller app could only be used to play music stored on a PC or media server connected to the same Wi-Fi network as an Android device. The update, Sonos said, will allow users to play music, podcasts, and any other audio files stored on as many Android devices as they'd like.
Unfortunately, the app still can't access music purchased through Google Play, but users can get around this problem by downloading their songs to a PC and then transferring them back to their Android device.

Will Kate Middleton's Royal baby be a Leo or a Cancerian? Twitter frenzy over child's star sign
- Baby will be a Cancerian if born before 4.54pm today but a Leo if born after
- Diana, Princess of Wales, was a Cancerian while Princess Margaret was Leo
- Old wives' tale says full moons cause many women to go into labour
- Duchess of Cambridge's labour coincided with July full moon at 11.16am
By Suzannah Hills
|
The nation is on tenterhooks as we wait to hear whether our future monarch is a girl or a boy but astrologers claim his or her star-sign can provide us with a telling picture of our future monarch.
The timing of the baby's birth today will dictate whether the baby is an emotional Cancerian or fiery Leo, astrologers say.
If the child is born before 4.54pm today, it will be a Cancerian, like its father Prince William and grandmother Diana, Princess of Wales.
But if the baby comes later, astrologers say it will be Leo, like its great aunt Princess Margaret, Countess of Snowdon, and Princess Anne.?

Cancer or Leo? Never mind whether it's a boy or girl, astrologers claim the star-sign of Prince William and Kate's baby will have a bigger influence on the type of monarch it will become
The Duchess of Cambridge went into labour at 5.30am this morning - with many suggesting the? approaching full moon at 11.16am helped bring on the contractions.
?
Prince William is with his wife at the private Lindo Wing of St Mary?s Hospital in Paddington, west London, where he himself was born in 1982.
But as the country waits to hear whether Britain has a future king or queen, there was a Twitter frenzy this morning as to whether it would be born a Cancer or a Leo.
Astrologer with The Association of Professional Astrologers International, Deike Begg, says the timing of the baby's birth will play a huge role in their personality type.
Different personality types: Diana, Princess of Wales, pictured left at a Live Aid for Africa concert in 1985, was Cancer, while Princess Margaret, pictured in 1960, was a Leo
She said: 'If the baby is born before 4.54pm they will be a Cancer - like father William. But its moon will be in Capricorn - which is the same star-sign as mother Kate.
'This means the baby will share a lot of the parents' personality traits.
'As a Cancer, the child will be very family oriented like its parents and sensitive. Cancers often appear strong on the outside but are very soft on the inside.
'But with a Capricorn moon it would also be aware of its responsibilities and dependable.'
Traditionally those born under the star-sign of Cancer - generally between June 22nd and July 22nd although the exact dates vary slightly every year - are sensitive, caring, shrewd, family oriented and protective of their loved ones.
Sharing signs: If the baby is born before 4.54pm today it will a Cancerian like father Prince William, pictured left, with a moon in Capricorn - the same star-sign as mother Kate, pictured right
Famous Cancers include South African president Nelson Mandela, Hollywood actors Harrison Ford, Tom Hanks and Tom Cruise, and Edward VIII, who gave up the throne for American divorcee Wallis Simpson.
Prince William, who was born on June 21, is a Cancerian as was his mother Diana, Princess of Wales, whose birthday was July 1.
But while many people will only count the baby as a Leo if it is born tomorrow, Ms Begg says it will technically be a Leo if born after 4.54pm today.
She said: 'A baby chooses when it wants to be born. A Leo is born to be a king.?
'A Cancer would not be happy about being in the limelight whereas a Leo enjoys being the centre of attention.
'If the baby is born a Leo it will be more extrovert and confident.'
Typical Leo traits are said to include confidence, ambition, generosity and loyalty.
Waiting game: Members of the world's media gather outside The Lindo Wing as The Duchess Of Cambridge goes into labour at St Mary's Hospital in London today
Famous Leos include Princess Margaret, Madonna, US President Barack Obama and actress Jennifer Lawrence.?
But other astrologers claim the baby will have a 'very Cancerian personality' even if it is born Leo as it will be right on the cusp of the sign.
Astrologer Patrick Arundell said the future king or queen would be more conventional if a Cancerian, but more of a ground-breaker if born tomorrow as a Leo.
'Either way, he or she is going to be larger than life, charismatic and glamorous but they will have a very Cancerian personality, whether under the sign of Leo or not, and be sensitive and caring,' Mr Arundell said.
He added: 'If the baby's born today it will have a slightly more conventional and conservative personality, but if it's born tomorrow it will be more groundbreaking and more in tune with modernity.'
Mr Arundell said the baby would also have a lot of 'go-get energy' and star quality.
'Mars and Jupiter are conjunct in Cancer and that will give the baby a tremendous amount of go-get energy and that is already in motion,' he said.
He added: 'Venus and the Sun are also in a magnetic connection which will give the baby a star quality and a sparkling charisma.'
Famous Cancers: Former South African President Nelson Mandela, pictured, actors Tom Hanks and Tom Cruise were all born under the Cancer star-sign
Meanwhile there have been numerous theories as to what caused the Duchess of Cambridge to go into labour - whether it was the full moon, an electrical storm or just conventional 'Baby Mean Time'.
Maternity wards are said to be busier during a full moon, although there is debate in the medical world about whether the moon does encourage women to go into labour.
Mervi Jokinen, of the Royal College of Midwives, said midwives often talk of how the full moon makes for a busy spate of deliveries.
'It's always sort of been an old wives tale saying that the full moon brings women into labour. Midwives usually do say "I'm on call. It's a full moon. I'll be busy tonight",' she said.
'There was a study about 20 years ago at a hospital near the River Thames which is a tidal river and it showed that on the full moon they did have more births.
'The idea is that because the baby is surrounded by water, the time of the full moon and the high tide causes the waters to break. But there's not enough scientific evidence to show it's proven.'
Birth coach Zara de Candole, of Doula UK, said: 'As a doula (birth coach) who has supported many women in labour, there does seem to be some link between labour kick starting and a full moon.'
Extroverts: Madonna, pictured, Barack Obama and Princess Margaret were all born under the star-sign Leo
There are also suggestions electrical storms and a drop in barometric pressure can bring on labour.
Western central London - near where William and Kate's Kensington Palace apartment is based - experienced isolated heavy rain, thunder and lightning strikes at 6am this morning - just at Kate was admitted to the Lindo wing of St Mary's Hospital in Paddington.
Chris Burton, a forecaster with MeteoGroup, the weather division of the Press Association, said: 'The storm affected western central London. There were lightning strikes at around 6am and very localised, intense heavy rain and thunder.
'We've had high pressure with the sunshine but now there's low pressure and it's hot and humid which can cause thunder storms.'
Mervi Jokinen said she had not seen a connection between labour and electrical storms.
'We are full of electrolytes but I don't know. it's not something we've discussed as a midwific community. I can't vouch for that,' she said
She added that babies also arrived to their own agenda and their own time scale and put in an appearance when they are ready.
'Nature has its own way of preparing for labour. Before the baby comes, the body need to do some preparations and that's very important,' she said.

Stocks waver after fourth-straight winning week
stocks 
33 minutes ago
Stocks struggled for direction on Monday, after the Dow and S&P 500 logged their fourth-straight week higher, pressured by some mixed earnings reports.
The Dow Jones Industrial Average opened in negative territory, dragged by McDonald's and was down 13 points in early trading.
The S&P 500 and the Nasdaq wavered in a narrow range at the opening. On Friday, the S&P 500 posted a three-day winning streak to log a record close?its 22nd this year.
The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, traded near 12.
Dow component McDonald's registered quarterly earnings that missed both for bottom-line profit and top-line revenue.
The fast food chain saw earnings of $1.38 per share against expectations of $1.40 and revenue of $7.08 billion that fell short of estimates for $7.1 billion. Shares dropped about 2.4 percent in initial reaction to the report, sending stock futures well off their morning highs.
(Read More:McDonald's finance guide 'insulting' to low-wage workers)
Around 20 percent of S&P 500 companies have already reported, with 65 percent beating earnings estimates and 51 percent beating on revenues, according to Reuters. If all remaining companies post earnings in line with forecasts, earnings will be up 2.9 percent on the year before.
This week will be the busiest in second-quarter earnings season, with about a third of S&P 500 companies due to report, plus eight Dow-listed companies.
European and Asian shares ticked higher, boosted by upbeat earnings and an electoral victory for Japanese Prime Minister Shinzo Abe's coalition, signaling a green light for future monetary stimulus.

Deepika Kumari shoots gold, India finish fourth in Archery World Cup
Powered by Deepika Kumari's gold and bronze medal performances on the concluding day, India finished fourth in the Archery World Cup Stage 3 in Medellin, Colombia.
The world number three recurve archer Deepika shot four perfect 10s in windy conditions to lead India to a 201-186 thrashing of China for the team gold medal yesterday.
It was India's first World Cup team gold since Shanghai 2011.
Later, Deepika paired up with Atanu Das to win the mixed team bronze with an 18-point margin (150-132) against the Mexicans.
India thus finished fourth with one gold and two bronze as the US topped the standings with nine medals (2-5-2), while China (2-1-2) and Colombia (1-1-0) were second and third respectively.
Top-seeded China comprising London Olympics team silver medallists Xu Jing, Cheng Ming and Cui Yuanyuan, an individual winner in Antalya, were the favourites with a 7-4 head-to-head track record.
But China had a disastrous first end with Ming missing the target completely and failing to register a score while Jing and Yuanyuan came up with 6 and 5.
The other two Indian members Rimil Buriuly and Bombayla Devi Laishram managed 11 between them while Deepika had an 8 to open up a massive 46-33 lead after the first end.
It was too late for China to stage a recovery as India extended their lead to 147-134 before the last six arrows.
The Chinese trio tried hard but it was difficult to hit the perfect 10s in windy conditions as Deepika showed class to ensure the gold by a handsome 15-point margin.
The next and last World Cup stage of the season before the Paris Final is scheduled in Wroclaw, Poland from August 19-25.

What You WILL NOT Hear In Your Social Justice Jesus Church: GOD Expressed Through Prof Anthea Butler What It Would Take For You TO CURSE HIM, Thus Exposing The GOD That You Actually Worship
GOD SHOWED HOW TO COMPEL A NON-BELIEVER HOW TO CURSE HIM BEFORE THE CONGREGATION - HIS PURPOSE WAS TO EXPOSE THE CONGREGATION ?TO ITSELF - NOT BY THE NUMEROUS "AMENS" THAT WERE SAID IN THE CHURCH TO AFFIRM THE?SACRILEGE?- BUT AS?EXPRESSED?BY THE THE SCARCE NUMBER OF "CHRISTIAN DISCIPLES" WHO CUT HER MICROPHONE OFF SO THAT SUCH IGNORANCE COULD NOT BE PROPAGATED IN "GOD'S CHURCH"
CLEARLY - These Disciples DON'T WORSHIP In "God's Church" - As They Can Show You That Their Own Names Are On The "Title Deed" Of The Building
ANALYSIS
For the first time in its existence on the North American Continent - the AMERICANIZED NEGRO is rapidly entering into an interval of time where its own COMMUNITY GOVERNANCE will be based NOT ON A DEFENSIVE POSTURE AGAINST RACIST TERRORISTS - but upon its ability to FIELD A "BLACK COMMUNITY GOVERNANCE CULTURE" that can compel its HUMAN RESOURCES to yield "THEIR SELFISH WILL" for the benefit of the COMMUNITY COLLECTIVE.
Much is written about the WHITE RIGHT WING RACIST who is shuttering at the loss of "White Power" in America.
Those who practice "Keep Your Enemy On Trial" are unwilling to do a concomitant psychological inspection upon "The Americanized Negro" as to what his fate will be as the "Progressive-Secularist Majority" takes the rungs of control over the nation.
The "Justice For Trayvon Martin Struggle Motion" is a case study on how the "Local Fire Trucks" from the Black community can be symbolically employed for a "Justice Cause" - while in the process of "Nationalized Congregational Unity" - summarily leave the LOCAL mission accomplished zones that volunteer their apparatus to the cause - are left VULNERABLE as the areas of protection that they were procured for is left exposed.

- GOD Turned His Back - Allowing The Jury Ruling In Sanford To Follow Its Own Course

Tour de France 2013: a British win at a French passion
Briton Chris Froome won the 100th edition of the Tour de France, a now globalized race that has its roots in the French love of cycling.
2013 Tour de France cycling race winner Christopher Froome of Britain, wearing the overall leader's yellow jersey, crosses the finish line with a teammate in the last stage of the 100th edition of the Tour de France cycling race, which is over 133.5 kilometers (83.4 miles); starting in Versailles and finishing in Paris, France, Sunday.

It?s the second time a Briton has won the Tour de France in two years. And with Mr. Froome?s clear lead in this year?s Tour lies the prospect that Britain could dominate cycling?s most famous race for many more years to come.
France hoped for more in the 100th ?edition of the race, after going nearly 30 years without a winner. Instead, the Tour de France, which was begun by a French newspaperman in 1903, has become the essence of globalization: It is broadcast into 190 countries; it?s dominated by American and English riders and fans the world over; and they speak far more English than French these days. Plus, for a race that was a smash based on a simple European ??especially French ??love of cycling, modern times have seen it overshadowed by international ??especially American ??doping scandals.
But if the French are missing on the podium tonight, on the streets of Paris?Sunday?cynicism was scarce. For the 100th ?race, the riders finished in twilight, with a gorgeous, hazy moon lingering on the horizon, the first night-time finish in the Tour?s history. And from its start in Corsica, through the countryside, valleys, and mountains of this country, it?s been, experienced, as always, as a 100 percent French affair.
?The popularity now is global of course,? says?Graeme Fife, author of ?Tour de France: the history, the legend, the riders.? ?But?its evolution since 1903 has really been rooted in the love of French people for the race.?
Despite not having a winner, the French did manage to succeed in pulling off an event that was not dismissed at large by the public, after the exploits of disgraced American rider Lance Armstrong, who admitted this year to doping for each of the seven consecutive years he won the Tour from 1999 to 2005.
At a patch of tonight's final stage?next to the Louvre Museum were not doubts and dismissals but enthusiasm. ?Anyone who is able to participate in this race is privileged,? says Guillermo Duran, a Colombian who has lived in France for 22 years but was here tonight to cheer on?Nairo Quintana, a Colombian whose team finished second.?
Suspicions of doping did, and will continue, to accompany cycling. Froome?s clear physical lead in this year?s Tour raised questions about whether he and is his team were clean.?"I just think it's quite sad that we're sitting here the day after the biggest victory of my life ... quite a historic win, talking about doping," Froome told reporters after a stage win on Mont Ventoux. "Here I am basically being accused of being a cheat and a liar and that's not cool."?
While it?s the British who are celebrating their superiority in this year?s race, the French, who have not?won the Tour since 1985 with Bernard Hinault, had at least one stage to call their own. Rider Christophe Riblon won the L?Alpe d?Huez stage, considered the most iconic, and among the toughest, of the Tour.?
"A Frenchman winning on L'Alpe d'Huez is a beautiful recompense for France and for the? Tour de France.?We, the French, France, our team, didn't deserve to come out of this? Tour de France?without a stage victory," said Mr. Riblon, quoted in the Washington Post.
The Tour de France has always awed the globe for the fortitude of its cyclers, their ability to endure wind, and rain, and ? like this year ? brutal heat, over some 2,000 miles. For the French, it?s also been about heroism and renewal.
When it began in 1903, France was still reeling from military defeat in the Franco-Prussian war of 1870. ?They generated the image of [the riders] as heroic, tough ? people who could overcome terrible difficulties,? Christopher Thompson, the author of "The Tour de France: A Cultural History? and a professor of French history at Ball State University, told The Christian Science Monitor upon this year?s start.?
That held true throughout the first half of the 20th ?century, each time the race was started up again, after pauses during the world wars. Then they were dubbed tours of ?renewal,? says Mr. Fife. And that?s a theme that?s re-emerged over the years in the wake of doping scandals, leaving some fans scoffing, others to abandon the sport altogether, but others coming back to the fold.
It is perhaps in the French countryside that support has barely ebbed, with spectators lining up for hours ? picnics in hand ? to watch the pack of cyclists speed by. It is the essence of a French summer. In Paris, the race?s international flare is more apparent ? with the French vying for a post with the city?s hordes of tourists?
But it?s still something the French take pride in. ?Today it?s a global event. More English is spoken than French,? says Armand Bouissou, who has watched the race each year since he can remember. ?And it?s been marred by the doping scandal. But on the days of the race, that falls into second place.??
?The tour is not just about the cyclists, it?s about all the people who come out to watch,? he says. ?

Thursday Market grows with Global Credit Union partnership
The Thursday Market has been bringing fresh produce and local goods to the South Perry District for the last eight years. With their eyes on the future, the market has teamed up with Global Credit Union to initiate new programs to build and sustain the summer favorite.
?
?It's just going to help us get organized a little bit better,? MaryAnne Delaney, Thursday Market Director of Marketing, says of the partnership with Global Credit Union. Global chose the market as one of their 2013 signature giving projects giving the market $10,000 to work on growth projects.
?
Delaney and other market organizers submitted a proposal to Global that outlined their plans for desired programs. It took a long time for the market to reach out to the business community for sponsorship. Delaney explains they had been reluctant in the past because they wanted a very specific partner.
?
?We wanted to make sure it would be a good fit for the market,? says Delaney. They wanted a group that was community minded and would be interested in hands-on involvement. Global fit the bill and new programs are already in place with others on the way soon.
?
Last week, the market began it's new customer loyalty program. The punch card system rewards shoppers with a $5 market voucher once they make 10 market purchases. The Global money contributes $3 to the voucher, with the market and vendors each provide $1 to make up the total.
?
?What we're trying to do is get people to think of the market as a place to shop,? says Delaney. The goal of the loyalty program is to get more people to do their general grocery shopping at the Thursday Market.
?
Another program on the list that will launch this summer is Friends of the Market. For a $25 donation, friends will receive a Thursday Market shopping bag, magnet, bumper sticker and poster to show their support of the farmer's market. Delaney explains that funds generated will help the non-profit market pay for expenses. She adds that since they have a limited vendor space, it is important to bring in other forms of revenue.
?
Global is already joining the market with community involvement. As part of the partnership, Global employees will be hosting a kid's activity tent three times this season. At today's market they were helping children make vegetable imprint paintings. Global will also be getting involved by delivering market food donations to the Refugee Harvest program.
?
The funds are also helping the Thursday Market step up their social media presence and improve their website. It will enable them to have staff to handle those things so the market manager can focus on the day to day operations and vendor relations. Delaney says the money from Global also helped purchase some odds and ends that the market was in desperate need of.
?
?I love the market,? says Delaney. The Thursday Market sees an average of 1,2000 customers a week, and with the ability to implement these new programs Delaney hopes the market will only grow in the coming years.
?
The South Perry Thursday Market is every Thursday from 3pm-7pm in the parking lot of The Shop and Grant Elementary. The market will be featuring vendors through Halloween. ?You can follow the Thursday Market on Twitter @ThursdayMarket

Barbie fights for her life
NEW YORK (AP) ? As far as catfights go, this is a doozy.
Barbie, long the reigning queen in the doll world, has suddenly been thrust into the battle of her life.
But Barbie's competitors look nothing like the blue-eyed, blond-haired, long-legged fashion icon. And they don't have the same old standards of beauty as the aging diva either.
Monster High dolls, vampy teens that are patterned after the offspring of monsters like Dracula and Frankenstein, have neon pink and green streaks in their hair. They wear platform heels and mini-skirts with skulls on them. And the dolls that go by names like Draculaura and Ick Abbey Bominable are gaining on Barbie.
In the Maddux household in Portage, Wis., for instance, Olivia, 10, has been playing with Barbie for six or seven years. But she added Monster High dolls to the mix a year ago.
"I look at Olivia and some of her friends and see they're growing out of Barbies," says Olivia's mom, Lisa Maddux, 42, a freelance writer.
That Barbie is losing her edge is no surprise. Since debuting in 1959 as the world's first fashion doll, Barbie has long been a lightning rod for controversy and competitors.
To be sure, Barbie is still No. 1 in the doll market, and the Mattel franchise is with an estimated $1.3 billion in annual sales. But Barbie's sales have slipped for four straight quarters, even while the overall doll category is up 6 percent year-to-date, according to the researcher NPD Group.
Meanwhile, Monster High, which is also made by Mattel, has become the No. 2 doll brand in just three years, with more than $500 million in annual sales, says BMO Capital Markets Gerrick Johnson.
In addition to the competition from Monster High, Barbie has had to contend with increasing criticism of her impossibly proportioned body. While the 54-year-old doll has over the years graduated from pin-up girl to a range of characters that include astronauts, engineers and princesses, detractors continue to dismiss the 11.5-inch doll's frame as impossibly top-heavy and tiny-waisted.
Barbie's measurements equate to about a 39-inch bust, 18-inch waist and 33-inch hips on a life-size woman. The average American woman, by comparison, is about a size 14.
Artist Nickolay Lamm on Monday posted pictures of what the doll would look like if it had the average measurements of a 19-year-old, revealing a much more meaty physique. The pictures were featured on Web sites from CNN to Time and renewed controversy over the doll's effect on girls' body image.
Monster High dolls, on the other hand, although still pretty slim, have a punk rock look that's intended to send the message that being different is OK. And they're aimed at slightly older children ? adding to their appeal ? while Barbie's increasingly young audience is hurting sales. After all, no child wants to play with anything seen as a baby toy.
Barbie marketed to children that are between age 3 and 9, but over the past 15 years or so, the range has shrunk to around 3 to 6, Silver, the toy analyst says. This has happened because older children are likely gravitating toward electronic devices or dolls like Monster High, which are aimed at kids 6 to 13, Silver says.
It's a trickle-down effect: The same reason why 5-year-olds who belted out "The Wheels on the Bus," 25 years ago would today be more interested One Direction boy band pop songs, he says.
"Kids are growing up much faster younger," Silver says. "A 6-year-old is looking for something a little edgier. That's the reason why Monster High has had so much success."
Kim Blake's daughter Sarah, 7, used to be a Barbie fan, but she's moved beyond that. She's getting ready to donate her 3-foot tall Barbie dream house and about half of her 20 Barbie dolls to charity.
Now, she's more into playing outside or taking Taekwondo martial arts classes and less into dolls in general. That's a switch from her mother, 35, who played with Barbie dolls until she was 13.
"Her girlfriends don't play with them any more either," says Blake, a store manager in Renton, Wash. "They've actually said the word 'babyish' talking about them."
The last time Barbie wasn't feeling the love was about 12 years ago when, after years of little competition, pouty-lipped Bratz dolls became wildly successful. They sent squeaky clean Barbie into a sales spiral.
Bratz dolls were edgy. They wore low-rise jeans, had heavy makeup and exposed navels. And they were sultrier than Barbies. But the Bratz fad faded in 2005, and Barbie slowly regained sales ground.
The same may happen with Monster High dolls. Industry experts say it will take a lot to dethrone the Barbie. "It's still one of the strongest brands in industry," says Needham & Co. toy analyst Sean McGowan.
In a call with investors on Wednesday, Mattel CEO Bryan Stockton admitted that the success of Monster High and its other doll brands might be causing some of Barbie's sales dip. But he points out that Barbie's sales are higher now than when Monster High dolls were launched in 2010. He said the competition is energizing the entire doll sector.
In general, "hot toys" have a cyclical nature, usually with a 5-year time span, says BMO Capital's Johnson. This ensures that no toy stays on top forever. Even evergreen brands that endure for decades, like Barbie, have highs and lows in popularity.
"It happens with everything ? name a toy, and it's had its ups and downs," Johnson says. "At some point the day comes when a kid says, 'Nah, I'm tired of this.'"
That day isn't completely here for Olivia Maddux yet. Her mom, Lisa, believes her new love affair with the Monster High dolls may have in fact extended the life of Barbie dolls.
"I think the addition of Monster High dolls, aimed at a little different demographic, kept Barbies alive in our place, since she plays with them together," she says.
That may be true. In Olivia's world, the two ? Barbie and Monster High ? peacefully coexist. Well, sort of.
"The Monster High dolls are like the Barbie's servants," Olivia says.

Bohmian mechanics, a ludicrous caricature of Nature
Some people can't get used to the fact that classical physics in the most general sense ? a class of theories that identify Nature with the objectively well-defined values of certain (classical) degrees of freedom that are observable in principle and that evolve according to some (classical) equations of motion, usually differential equations that depend on time, mostly deterministic ones ? has been excluded as a possible fundamental description of Nature for almost a century.
Classical physics has been falsified and the falsification ? a death for a theory ? is an irreversible event. Nevertheless, those people would sleep with this zombie and do anything and everything else that is needed (but isn't sufficient) to resuscitate it. Of course, it's not possible to resuscitate it but those people just won't stop trying.
Bohmian mechanics, one of the main strategies to pretend that classical physics hasn't died and hasn't been superseded by fundamentally different quantum mechanics, was invented by Prince Louis de Broglie in 1927 who called it "the pilot-wave theory". In the late 1920s, the 1930s, and 1940s, physicists were largely competent so they didn't have any doubts that the pilot wave theory was misguided by its very own guiding wave ;-). Exactly 25 years later, the approach was revived by David Bohm who made the picture popular, largely because he was a fashionable, media-savvy commie (he's almost certainly the recipient of Wolfgang Pauli's famous criticism "not even wrong" that was ironically hijacked by aggressive Shmoitian crackpots in the recent decade). Prince Louis de Broglie liked the new life that apparently returned to the veins of his old sick theory so he didn't even care too much that his theory was going to be attributed to someone else and that the someone else was a Marxist rather than an aristocrat.
A constraint that defines Bohmian mechanics is simple: it should be a classical theory that emulates quantum mechanics as well as it can. The champions of the Bohmian theory know that getting the same predictions as quantum mechanics is the maximum goal they may dream about ? they can never beat quantum mechanics ? and they sort of realize that even this tie is too much to ask in general. Most of the Bohmian advocates seem to know that their theory can't be accurate, especially because of its fundamental conflict with relativity ? but they don't seem to care. The fact that the Bohmian mechanics agrees with their fully discredited preconception that Nature is fundamentally classical is more important for them than the (in)accuracy of the predictions extracted from their pet theory.
It's straightforward to explain why it's possible to design a classical theory that parrots quantum mechanics when it comes to certain questions.
Bohmian mechanics is at least vaguely defensible in the non-relativistic quantum mechanical models only; in more general theories, it collapses completely. How does it rebuild non-relativistic quantum mechanics for one particle, for example?
Proper quantum mechanics of this system may be written down in Schr?dinger's picture that dictates the following time evolution to the wave function:\[
i\hbar\frac{\partial}{\partial t}\psi(q,t)=-\sum_{i=1}^{N}\frac{\hbar^2}{2m_i}\nabla_i^2\psi(q,t) + V(q)\psi(q,t)
\] The way how this wave is evolved in agreement with the equation above contains all the "mathematical beef" of quantum mechanics for the given system and to get the right numbers, any classical caricature of quantum mechanics simply has to contain some objects that are pretty much equivalent to \(\psi(q,t)\). These objects are then assigned totally different, wrong interpretations in the caricatures but they must be there and they must evolve according to the same Schr?dinger's equation.
Bohmian mechanics buys \(\psi(q,t)\) and incorrectly interprets it as a classical wave ? a field that has objective values and is in principle measurable. Of course, we know from quantum mechanics as well as experiments that the value of the wave function simply shouldn't be and isn't measurable in a single repetition of an experiment. So the Bohmian apologists must also invent convoluted mechanisms to make the wave unmeasurable ? because it is unmeasurable according to the experiments ? despite the fact that the wave function is fundamentally measurable in their theory.
Bohmian Rhapsody, via Dilaton.
Is this the real life? Is this just fantasy?
Caught by the guiding wave. No escape from reality.
Open your eyes. Look up to the skies and see:
I'm just [a] state vector, I need no images.
Because I'm easy come, easy go.
A little high, little low.
Anyway the [pilot] wave blows, doesn't really matter to me, to me.
The pilot-wave theory adopts \(\psi(q,t)\) as an objective classical wave ? which it gives a new name, the "guiding wave" or "pilot wave" ? but in order to agree with the fact that particles may be observed at sharp locations despite the fuzziness of the wave functions associated with them, they must add some additional degrees of freedom: the actual classical position of the particle. The defining philosophy of Bohmian mechanics is that the actual, classical position of the particle is "guided" by a function of the classical field emulating the wave function so that the probability distribution for the particle's positions remains what it should be according to quantum mechanics. For example, the laws that guide the actual classical particle must be such that they repel the particle from the interference minima in a double-slit experiment:
The right end of the picture (the photographic plate) shows denser and less dense regions, the interference maxima and minima.
Can you find the appropriate rules for one non-relativistic spinless quantum particle that is able to do it in a way that imitates quantum mechanics? You bet. All the tools are available in conventional quantum mechanics for this system. Recall that in quantum mechanics, \(\rho=|\psi(q,t)|^2\) is the probability density that the particle is sitting near location \(q\) at time \(t\). But quantum mechanics also allows you to define the probability current\[
\bold j = \frac{1}{m} \mathrm{Re}\left ( \psi^*\bold{\hat{p}}\psi \right )
\] Note that it is again sesquilinear (bilinear with one star) in the wave function. We act on the wave function by the momentum operator \(\bold{\hat{p}}=-i\hbar\nabla\), multiply the result by \(\Psi^*\) just like when we calculated the probability density, take the real part, and divide it by the mass \(m\). You see that it only differs from the formula for the probability density by the extra operator \(\bold{\hat{p}}/m\), the operator of the velocity \(\bold{\hat v}\), inserted in the middle. The real part could have been added to the probability density as well because it was real to start with.
At any rate, if you define the probability density and the probability current correctly, they obey the continuity equation\[
\frac{\partial \rho}{\partial t} + \bold \nabla \cdot \bold j = 0.
\] The divergence of the probability current exactly agrees with the decrease of the probability density in the given region. It means that the probability current measures how the probability has to flow into/from a given infinitesimal volume if you want the probability density to change just like it should according to Schr?dinger's equation.
Now it's easy to realize that if you define a classical "velocity field"\[
\bold{\hat v} = \frac{\bold{\hat j}}{\rho},
\] it will be very useful for emulating quantum mechanics. It's not hard to prove that if you define Bohmian mechanics as the "classicalized" wave function together with a classical position \(\bold{\hat q}(t)\) that evolves according to the "guiding equation"\[
\ddfrac{\bold{\hat q}}{t} = \bold{\hat v} (\bold{\hat q}(t)),
\] the trajectories of the classical particles will be repelled from the interference minima, attracted to the interference maxima, and will obey a more specific rule: If you imagine that the particles in the initial state are distributed according to the probability distribution given by \(\rho(\bold{\hat q},t)\), it will be true for the final state, too.
This trick may be generalized to the case of \(N\) non-relativistic particles. In this case, the wave function \(\psi\) becomes a classical wave that is a function of the \(3N\)-dimensional configuration space. This configuration space is larger than the ordinary space and is "multi-local" and because we have this "multi-local" old-fashioned classical field, the theory becomes explicitly non-local and a violation of the Lorentz symmetry, at least in principle, is inevitable.
I would like to emphasize that it's no surprise at all that it's possible to find the equation that evolves the probability distribution in the right way. Imagine that you start with a wave function \(\psi(\bold{\hat q})\) at some time \(t_0\). Throw a trillion of dots ? particles ? to the space that are distributed according to \(\rho = |\psi|^2\). Do the same thing for the final moment \(t_1\) when the wave function is different. You will have two configurations of trillions of particles. It's not shocking that you may "connect the dots" from the initial state to the final state in some way.
A way that is simple enough, one based on the probability current and described above, gives you one of the solutions. But it's not the only solution. In reality, the "initial dots" could be connected with the "final dots" in infinitely many ways (well, a "mere" trillion factorial if you only have a trillion of dots). In the continuous language, you could e.g. make the particles move along spirals inside the cylinders that surround the interference maxima. Is one way to connect the dots better than others?
Of course, it's not. All of them are equally good. Quantum mechanics commands you to learn something about the initial state ? some wave function or density matrix that encode the initial probability distribution ? and it allows you to predict the probabilities for the final state. But it doesn't tell you which of the initial particles is connected with which final particle, i.e. how to connect the dots. It doesn't inform you about any preferred classical trajectory that connects them (and Feynman's approach orders you to sum over all trajectories). If you could actually "measure" this permutation that determines how the dots are connected, quantum mechanics would be shown incomplete.
However, it's totally obvious that there's no way to measure the trajectories or permutations inside. The particles just don't have well-defined, in principle measurable trajectories between the measurements for the usual Heisenberg uncertainty principle-based reasons. If you tried to measure the trajectory before the final measurement, you would change the experiment and destroy or damage the final interference pattern. So all the precise lines on the "caricature of the double-slit experiment"
are pure fantasy. They're just crutches for the people who need some specific picture of the intermediate states to be drawn. But the specific picture we drew is in no way better than infinitely many other pictures we could draw that would predict the same interference pattern, the same probability distributions for the final state. Everything we added because we wanted the physical system to have objective properties prior to the measurement ? because we're bigots who can't accept the fact that classical physics has died ? is unphysical. The added value is purely negative. Everything we added to get from proper quantum mechanics to Bohmian mechanics is rubbish. And many things we're forced to lose when we switch from quantum mechanics to Bohmian mechanics are essential.
Because the wave function has a probabilistic interpretation in proper quantum mechanics (it is a ready-to-cook meal from which one may quickly prepare various probability distributions by a calculation), it doesn't matter that it spreads. The spreading of the wave function doesn't make the world more fuzzy. It only makes our knowledge about the world more uncertain. But once we learn the answer to a question ? e.g. about the position of a particle ? the world fully regains its sharp character it boasted at the beginning. If you only know that the probability of 1,2,3,4,5,6 are 1/6 for some dice in Las Vegas, it doesn't mean that the dice became structureless balls or that the digits written on their sides have become fuzzy or mixed or smeared. It just means that we have one equally sharp cubic die but we just don't know its orientation in space. The uncertainty coming from quantum wave functions are analogous ? they only differ from the "classical uncertainty" by their inevitability.
That's not the case of Bohmian mechanics. The wave function is interpreted as a classical field of a sort and it is objectively spreading. So something objective is being diluted all over the Universe. That's terrible because this objectively makes the Universe increasingly more fuzzy and bizarre. The useless parts of the guiding wave ? the "classicalized" wave function ? should be killed in some way because they became useless. But Bohmian mechanics doesn't imply anything of the sort. If you want to clean the garbage of the no-longer-needed branches of the wave function, you will have to add another independent contrived mechanism. Such a mechanism will be a new source of a violation of the Lorentz invariance.
(You also need a special mechanism that prepares the guiding wave in a certain initial state and one more mechanism that distributes the "actual particle" inside the appropriate distribution with the right odds because these two things don't follow from Bohmian mechanics as we have defined it above, either. Most of these things are ignored by the Bohmists. Note that with the right probabilistic interpretation ? quantum mechanics directly connects the knowledge about the past with the knowledge about the future, without any new crutches in between ? we don't need to invent any new mechanisms.)
I think that a sane, critically thinking person must be able to realize what he is doing if he is doing such things. He is drawing a ludicrous caricature of Nature ? a physical system that is actually governed by the laws of proper quantum mechanics ? that reproduces some properties of the correct, quantum theory. The project of drawing the caricature is motivated by the desire to defend a philosophical dogma that the world is fundamentally classical even though it is clearly not. If he has at least some conscience, he must feel analogously as if he were counterfeiting a $100 banknote. He must know that what he is producing isn't the "real thing"; it is just a forgery that can bring him greater personal benefits than the actual banknotes but that's where the advantages stop.
But every change from the proper quantum mechanics to the pilot-wave theory is clearly wrong ? the "added value" is unquestionably negative. Because the Bohmists don't like the probabilistic character of the wave function, they turn it into a classical wave ? the guiding wave. But a classical wave that spreads objectively makes the world ever more fuzzy. So one has to introduce new tricks to have a chance that this increasing fuzziness doesn't spoil the world. All these tricks ? tricks that can't really ever be defined in such a way to imitate quantum mechanics completely accurately ? have to be considered and added just in order to mask the fact that the wave function is simply not a classical field.
It's fair to say that the claim by quantum mechanics that the wave function is not an objectively real wave or field that can be in principle measured is something that we have proven by direct experiments. Attempts to pretend that the wave function is a classical wave are just attempts to mask the truth. I am confident that every Bohmist must ultimately realize it is so and he must be dishonest if he claims that his efforts are more justifiable than the efforts of creationists who are trying to obscure the explicit evidence in favor of evolution: they are exactly equally unjustifiable.
Moreover, it's sometimes being said or thought that the perfect emulation of quantum mechanics can be done. Because the invalidated dogma that Nature is fundamentally classical is holy for these bigots, they think that it should be done, too. But the truth is that it can't be done for a general physical system and for a general choice of observables we may measure in actual experiments described by general enough quantum theories.
Try to add the spin to a particle. If the logic of Bohmian mechanics ? the wave function "is" a classical field and we should also add some classical values of a maximum set of commuting observables ? were universally valid, it's clear that aside from the spinor-valued wave function \((c_{\rm up},c_{\rm down})\), we should also assume that Nature "objectively knows" about the classical bit of information that tells you whether the spin is "actually" up or down.
However, even the Bohmists realize that if every electron "objectively knew" whether its spin is up or down with respect to the \(z\)-axis, then the laws of physics would break the rotational symmetry because the \(z\)-axis would play a privileged role. Roughly speaking, the ferromagnets would always be oriented vertically, to mention an example. If the \(z\)-component of the classical angular momentum is quantized, it's totally obvious that the other components can't be quantized. A nonzero vector can't have integer (or half-integer) coordinates in each (rotated) coordinate system.
Because they sort of realize that the rotational symmetry holds exactly and the hypothesis that the classical value exists with respect to one axis would break the symmetry kind of maximally, they decide that the Bohmian rules must be "skipped" in the case of the spin ? they just manually omit some degrees of freedom that should be there according to the general prescription of Bohmian mechanics and hope that the spin measurements are ultimately reduced to position measurements so that it doesn't hurt if some degrees of freedom are not doubled in the usual Bohmian way.
The reason why the case of the spin is obvious even to them is the fact that different components of the spin are non-commuting observables none of which is more "natural" than others. After all, they are exactly equally natural because they are related by the rotational symmetry.
While the spin is an obvious problem, the pathological character of Bohmian mechanics is much more general. Every (qubit-like) discrete information in quantum mechanics ? information labeling a finite-dimensional Hilbert space ? is incompatible with the Bohmian philosophy. Recall that Bohmian mechanics added "classical trajectories" \(\bold{\hat q}(t)\) and these coordinates were functions of time that evolved according to some differential equations. But that was only possible because the spectrum of the coordinates was continuous. If you think about observables with a discrete spectrum, it just doesn't work because they would have to "jump to a different, sharply separated discrete eigenvalue" at some points and there can't be any deterministic laws that would govern such jumps.
Quantum mechanics tells you that a quantum computer composed of a very large number of qubits may perfectly emulate any quantum system. But that's not the case in Bohmian mechanics. An arbitrarily large quantum computer is composed of qubits, e.g. many electron spins, and because the spin isn't accompanied by a classical bit, Bohmian mechanics is forced to say that an arbitrarily large quantum computer only contains the "classicalized" wave function but no additional classical information analogous to the classical trajectories. So for a quantum computer, the whole "redundant superstructure" (which is how Albert Einstein called these extra coordinates ? he was a foe of the pilot-wave theory, despite his being a disbeliever in quantum mechanics) has to be omitted. This is quite an inconsistency in the Bohmian treatment of different quantum systems. The actual reason behind the inconsistency is clear, of course: some physical systems may be caricatured by the pilot-wave trick, others can't. But in Nature, there actually isn't any qualitative difference (in principle observable difference) between these two classes of situations.
I said that Bohmian mechanics doesn't allow you to consistently treat the particles' spin or any other discrete degrees of freedom, for that matter. But the inadequacy of Bohmian mechanics is much worse than that. It really doesn't allow you to correctly deal with most observables in general quantum systems, not even with observables with a continuous spectrum. I have discussed similar problems in Bohmists and the segregation of primitive and contextual observables four years ago.
The problem is that Bohmian mechanics forces you to choose some observables that "really exist" ? are encoded in the objective extra coordinates that are supplemented to the "classicalized" wave function. However, quantum mechanics implies that other observables just can't have a well-defined value at the same moment ? because they don't commute with the first ones, stupid. That also means that Bohmian mechanics can't have any answers to questions about the value of these observables.
The Bohmian trajectories in the picture above pretend that a particle has an objective position and an objective velocity. But what about the orbital angular momentum \(\bold{\hat L} = \bold{\hat q}\times \bold{\hat p}\)? A basic result of quantum mechanics is that the spectrum of \(\bold{\hat L}_z\) is discrete; the eigenvalues are integer multiples of \(\hbar\). Already this elementary fact in quantum mechanics ? even non-relativistic quantum mechanics ? is completely inaccessible to Bohmian mechanics. The cross product of the classical position and the classical momentum of the "added Bohmian trajectories" isn't quantized at all. It has really nothing to do with the angular momentum that can be measured.
And be sure that the measurement of the angular momentum is often ? e.g. for electrons in atoms ? much more natural and "fundamental" than the measurement of the particles' positions or momenta. It's because its eigenstates are much closer to the energy eigenstates and those are the most natural basis of a Hilbert space because they describe stationary ? and therefore lasting ? states. But such a direct measurement of the discrete orbital angular momentum can't be done in Bohmian mechanics. Instead, Bohmian mechanics tells you that you have to continue the evolution of the wave function according to the laws stolen from proper quantum mechanics up to the moment when you can actually convert the original measurement to a measurement of a location, and hope that Bohmian mechanics knows how to emulate the measurements of positions. It isn't quite the case, either, but even if it were the case, Bohmian mechanics is just bringing an amazing degree of inconsistency into the way how different observables ? different functions of the phase space ? are treated. A sensible theory should treat all functions of the coordinates and momenta i.e. all functions in the phase space equally, following unified rules. Quantum mechanics obeys this criterion, Bohmian mechanics doesn't. We could say that just like the solipsists say that their own mind is the only physical system that may be claimed to be self-aware, Bohmian mechanics remains silent and reproducing the (accurately emulated) quantum evolution up to the moment when macroscopic positions are apparently being measured (those are the "conscious events" that are supposed to replace quantum mechanics with something else). But in the real world, there's nothing special about the minds of the solipsists (except that they belong to the set of crazy people) and there's also nothing special about the positions of macroscopic objects in comparison with many other observables we may define.
In quantum mechanics, you may directly construct operators for the angular momenta and ask about their possible values, eigenvalues, and about the predicted probabilities that the measured value will be one or the other. It doesn't matter whether the angular momenta belong to large or small or conscious or unconscious objects. Quantum mechanics allows you to deal with all observables equally. In Bohmian mechanics, those things matter. Effectively, any measurement has to be continued up to the moment when it imprints itself into a position of a macroscopic object which Bohmian mechanics claims to reproduce correctly.
A totally new minefield for Bohmian mechanics is relativity. The minimum consistent relativistic theories of quantum particles are quantum field theories (QFTs). They include the spin; I have already discussed the Bohmian problems with the spin. But there are infinitely many similar problems. For example, you may choose many different bases of the QFT Hilbert space. They may be eigenstates of the occupation number operators; eigenstates of field operator distributions \(\hat \phi(\bold{x})\), and so on. It is not clear at all which of these observables are added as the "extra classical trajectories" to Bohmian mechanics. In fact, it is totally obvious that none of the choices will behave correctly in all the experiments that may test a quantum field theory. Also, you can't add many of them or all of them (e.g. both positions and particles and classical values of the fields) because it would be clearly undetermined which of these "added", mutually conflicting classical degrees of freedom defines the "actual reality" that decides about a measurement.
Sometimes, the value of the field at a given point may be measured, especially when the frequencies are low. So it would seem like you need to add a "preferred classical field configuration" to the Bohmian version of a QFT. However, especially for high frequencies, the quantum field manifests itself as a collection of particles so you may want to add the trajectories of the particles instead. Moreover, even if you represent a QFT as a system describing many particles, your Bohmian theory won't be able to deal with the basic and most universal processes that must exist in a QFT or any other relativistic quantum theory such as the pair creation of a particle and an antiparticle and their destruction.
If individual particles evolve according to the "guiding wave" equations we discussed at the beginning, it's simply infinitely unlikely (the probability refers to the selection of the initial positions from the distribution) that they will ever collide with one another. Two random lines in a 3D space simply don't intersect one another. But if they don't directly collide, it means that they can't annihilate! To allow the particles to annihilate (and be pair-created) with the (experimentally proven) nonzero probability, you would need to introduce a totally non-local extra dynamics that sometimes allows the particles to jump to a completely different place; or you would have to allow the annihilation of particle pairs that don't coincide in space. Any such an extra mechanism would force you to change the original laws of physics in a way that would almost certainly contradict some other experiments because the unmodified quantum laws simply work and it was a healthy strategy for you to emulate them "perfectly" at the very beginning. Such modifications would especially contradict some experimental tests of relativity because these modifications are so horribly nonlocal.
So you have no chance to construct an operational Bohmian caricature of a quantum field theory. Needless to say, the problems become even more extreme once you switch to quantum gravity i.e. string theory because many more observables have a discrete spectrum, there are many more ways to choose the bases, the nonzero commutators of various observables are more important than ever before, and Bohmian mechanics just can't prosper in such general quantum situations. On one hand, quantum gravity i.e. string theory is just another quantum theory. On the other hand, it is "more quantum" than all the previous quantum theories simply because the quantum phenomena affect many more questions that could have been thought of in the classical way if you worked with simpler quantum mechanical theories (for example, the spacetime topology ? especially the number of Einstein-Rosen bridges in the spacetime ? can't even be assigned a linear operator in a quantum gravity theory, as Maldacena and Susskind argued).
The non-local fields, collapses, non-local jumps needed for particle annihilations, and other things represent an inevitable source of non-locality that can, in principle, send superluminal signals and that consequently contradicts the Lorentz symmetry of the special theory of relativity. There's no way out here. If you attempt to emulate a quantum field theory in this Bohmian way, you introduce lots of ludicrous gears and wheels ? much like in the case of the luminiferous aether, they are gears and wheels that don't exist according to pretty much direct observations ? and they must be finely adjusted to reproduce what quantum mechanics predicts (sometimes) without any adjustments whatsoever. Every new Bohmian gear or wheel you encounter generally breaks the Lorentz symmetry and makes the (wrong) prediction of a Lorentz violation and you will need to fine-tune infinitely many properties of these gears and wheels to restore the Lorentz invariance and other desirable properties of a physical theory (even a simple and fundamental thing such as the linearity of Schr?dinger's equation is really totally unexplained in Bohmian mechanics and requires infinitely many adjustments to hold ? while it may be derived from logical consistency in quantum mechanics). It's infinitely unlikely that they take the right values "naturally" so the theory is at least infinitely contrived. More likely, there's no way to adjust the gears and wheels to obtain relativistically invariant predictions at all.
I would say that we pretty much directly experimentally observe the fact that the observations obey the Lorentz symmetry; the wave function isn't an observable wave; and lots of other, totally universal and fundamental facts about the symmetries and the interpretation of the basic objects we use in physics. Bohmian mechanics is really trying to deny all these basic principles ? it is trying to deny facts that may be pretty much directly extracted from experiments. It is in conflict with the most universal empirical data about the reality collected in the 20th and 21st century. It wants to rape Nature.
A pilot-wave-like theory has to be extracted from a very large class of similar classical theories but infinitely many adjustments have to be made ? a very special subclass has to be chosen ? for the Bohmian theory to reproduce at least some predictions of quantum mechanics (to produce predictions that are at least approximately local, relativistic, rotationally invariant, unitary, linear etc.). But even if one succeeds and the Bohmian theory does reproduce the quantum predictions, we can't really say that it has made the correct predictions because it was sometimes infinitely fudged or adjusted to produce the predetermined goal. On the other hand, quantum mechanics in general and specific quantum mechanical theories in particular genuinely do predict certain facts, including some very general facts about Nature. If you search for theories within the rigid quantum mechanical framework, while obeying the general postulates, you may make many correct predictions or conclusions pretty much without any additional assumptions.
If you ask any of the hundreds of questions (Is the wave function in principle observable? Are observables with discrete spectra fundamentally less than real than those with continuous spectra? Is there a way to send superluminal signals, at least in principle? And so on) in which proper quantum mechanics differs from Bohmian mechanics, the empirical evidence heavily favors quantum mechanics and Bohmian mechanics can only survive if you adjust tons of parameters to unnatural values (from the viewpoint of Bohmian-like theories) and hope that it's enough (which it's usually not).
In 2013, even more so than in 1927, the pilot-wave theory is as indefensible as a flat Earth theory, geocentrism, the phlogiston, the luminiferous aether, or creationism. In all these cases, people are led to defend such a thing because some irrational dogmas are more important for them than any amount of evidence. That's what we usually refer to as bigotry.
And that's the memo.
