Wednesday, July 4, 2007 The 9th summit of the Assembly of the African Union ended in Accra, Ghana just before midnight yesterday. The three day summit, which was scheduled to last until the afternoon of July 3 overran, ending just before midnight.

The main issue discussed was the call for the setting up of a Pan-African government. The Libyan leader, Muamar al-Gaddafi, and the Senegalese President, Abdoulaye Wade, were advocates for its establishment as soon as possible. Gaddafi was in favor of a single African army, foreign policy and government. Others such as Robert Mugabe and Thabo Mbeki were more inclined to a more gradual process of integration. Yoweri Museveni, of Uganda, preferred more economic integration to political union, as he felt Africa was too diverse to be under one government.

The African leaders put out a unanimous declaration agreeing to set up a Ministerial Committee to examine the relationship between an African Union government and the various national governments. The committee would also be expected to look at the impact on the sovereignty of member states and to provide a time frame and road map for the process.

The idea of a continental government was first advocated by Kwame Nkrumah of Ghana in the mid fifties and sixties when he was the Ghanaian president. It however received very little support at the time.

The host of the summit, John Kufuor of Ghana, Chairman of the Union, said there had been no winners or losers and that the debate had been characterised by tolerance and mutual respect. He said Africa’s union was not being modelled on that of the USA nor the European Union but rather on model that would be unique to the continent. He was also keen on the rationalization of the various Regional Economic Commissions towards the realization of an African Economic Commission.

The next summit is scheduled for Addis Ababa, Ethiopia in 2008.

Officials from TAG Heuer have announced that the company received the iF product design award, which was given away by the jury from the International Forum Design. TAG Heuer received the award for its concept watch, called Monaco Calibre 360 (Linear Second) Concept Chronograph.

The jury that gives away the iF product design awards each year consists of leading design experts from all over the world gathered in one place. The iF awards are presented in Hanover, Germany, at the International Forum Design Hannover GMBH. There are a number of fields and disciplines which have their own awards.

TAG Heuer’s Monaco Calibre 360 LS Concept Chronograph has won the award in the Leisure/Lifestyle category. The timepiece was chosen from over 2,200 watches from 35 countries. This prestigious award was given to the company for the second time in two years. Last year the winner in the same category was TAG Heuer’s Professional Golf Watch, designed together with Tiger Woods.

This year’s winning timepiece from TAG Heuer has a mechanical movement, which represents the first in the history of watchmaking to reach a precision of 1/100th of a second. The watch itself is to be seen at the iF design exhibition 2007, held in Hanover, from March 15 till August.

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.

A compilation of brief news reports for Thursday, August 13, 2009.

The French capital Paris has seen a second night of violence by demonstrators, who have blamed police for the death of a motorcyclist on Sunday.

On Sunday night youths in the eastern suburb of Bagnolet, set 29 vehicles alight and threw stones and petrol bombs at police. Monday night was “relatively calm” according to Samira Amrouche, spokeswoman for the regional administration, the authorities having depolyed 40 vans of riot police only 8 vehicles were burnt.

The motorcyclist, a pizza deliveryman, was killed when he fled police attempting to examine his documents, dying when he was struck by a pursuing police vehicle according to the youths,however in the police version his death was a result of him crashing into barriers.

The current violence has echoes of the unrest in 2005, with again dissaffected youths of Arab and black descent venting their anger and frustration.

The leaders of the North American Free Trade Agreement (NAFTA) met in Guadalajara, Mexico on Sunday and Monday. The leaders of the three countries (Barack Obama of the United States, Felipe Calderón of Mexico, and Stephen Harper of Canada) promised to work together on swine flu, organised crime and green issues.

Despite disputes in a number of areas remaining unresolved, the three leaders succeeded in presenting an amiable Three Amigos image. The three leaders expressed solidarity, and an understanding of each others position.

The unresolved issues include the buy American clauses in the US stimulus package, tit for tat reprisals by the Mexican authorities over Canadian visa restrictions on Mexican travellers, and the US ban on Mexican trucks from crossing the border.

Risking the ire of human rights activists back home President Obama expressed support for President Calderón’s war against drugs saying he had “great confidence” in the Mexican authorities.

Mexican Federal Police (Policía Federal) have foiled an alleged plot to assasinate the President of Mexico Felipe Calderón. Acting on intelligence gathered over a year the Federal Police arrested five drug cartel members on Sunday and publicly paraded their captives and a number of weapons ,including automatic rifles, on Monday. Speaking during a summit of North American leaders Calderón played down the threats on his life, saying that the cartels are being destroyed by his policies.

Some 11000 have died since President Calderón’s took office in 2006 and made the war on drugs a cornerstone of his administration.

Aung San Suu Kyi has been sentenced by a court in Burma to a further three years of house arrest for violating the terms of her previous sentence. However her sentence was immediately commuted to 18 months on the orders of Burmese head of state Senior-General Than Shwe out of respect for her father General Aung San and out of a desire for “national reconciliation”.

The period of her arrest will prevent Aung San Suu Kyi from participating in the general elections scheduled for 2010. The sentence was immediately condemned by Western leaders, and breaking from their usual silence, the Association of South East Asian Nations (ASEAN) through its current chair Thailand issued a statement expressing disappointment. The ASEAN statement and talk of further European Union and United States sanctions are unlikely to have any impact on Southeast Asian country given the support of India and China.

The Chinese issued a statement calling for the world to respect Burmese sovereignty and laws, and is seen as an indication that China, a veto power will not support any United Nations actions.

John Yettaw whose unauthorised visit led to Aung San Suu Kyi’s prosecution has himself been sentenced to seven years imprisonment, four of which will be for hard labour.

Four employees of the Rio Tinto Group have been formally arrested in China on charges of bribery and using improper practises in its negotiations with Chinese companies. The Chinese accuse the men of improperly learning the negotiating position of Chinese companies wishing to buy iron ore, and through this charging 700 billion yuan (US$102.46 billion) more then they would otherwise have been able to

The four were initially held on espionage charges and have been held since early July. The formal charges allows the Chinese authorities to hold the four a further seven months as it prepares its case against them. Their arrests followed the collapse of an attempted by Chinese owned Chinalco to raise its stake in the Anglo-Australian Rio Tinto Group to 18%.

Michael Jackson will be the star of a film to be released on October 28, some four months after his death. The film will be primarily cut from footage of Jackson rehearsing for the series of concerts that would have taken place at the O2 in London, but will also feature interviews with Jackson’s family and friends.

The film becomes possible after AEG Live, the promoter of the O2 concerts, reached an US$60 million agreement with Columbia Pictures for over 100 hours of footage of Jackson preparing for his swan song.

“He was the architect of ‘This is it‘, and we were his builders…” said Kenny Ortega, Jackson’s collaborator on the project “…it was clear that he was on his way to another theatrical triumph.”

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.

Speaker of the U.S. House John Boehner announced yesterday that he would agree to a two-month extension of the payroll tax cut. In an effort to end the impasse between the House and Senate, Boehner told Senate Democratic leader Harry Reid that he would schedule a House vote on the Senate version of the bill that would extend the tax cut, which was due to expire at the end of the year.

Speaker Boehner announced the agreement in a brief statement: “Senator Reid and I have reached an agreement that will ensure taxes do not increase for working families on January 1”. Boehner informed other congressmen of the deal in a conference call yesterday evening.

The House may pass the bill via unanimous consent today, which would not require the presence of all members. Boehner and Reid also agreed to a bipartisan negotiation committee to sort out differences and extend the tax cut for an entire year, a goal recently sought by Republicans in the House.

The extension of the payroll tax cut, which would prevent approximately 160 million Americans from seeing a tax increase in 2012, had already been passed by the Senate last weekend. Earlier yesterday, Senate Republican leader Mitch McConnell joined several other Republican Senators in encouraging the House to pass the extension.

Senate Democratic leader Harry Reid said that once the House acts, he “will be happy to restart the negotiating process to forge a yearlong extension.” At a news conference, Speaker Boehner issued a statement: “We have fought the good fight. Why not do the right thing for the American people even though it’s not exactly what we want.” President Obama also responded to the development in a statement: “This is good news, just in time for the holidays. This is the right thing to do to strengthen our families, grow our economy, and create new jobs. This is real money that will make a real difference in people’s lives.”

The tax cut extension impasse began when the House effectively rejected the Senate-approved version of the bill on Tuesday after being faced with opposition from House Republicans, specifically those associated with the Tea Party movement, who advocated for spending cuts and the controversial Keystone XL oil pipeline.

Chile is celebrating its Bicentennial, with several events that have been organized by the government for almost a decade. It commemorates two hundred years since the First Government Junta of 1810 was formed, starting the Independence process, that ended in 1818 after Bernardo O’Higgins proclaimed it.

The Bicentennial takes place on a holiday from September 17th until 21st. Sebastián Piñera inaugurated the official fondas (places where typical food and drinks of Chile are sold; similar to a tavern) earlier on Friday. Piñera also danced a “pie” of Cueca, Chile’s national dance, with Government Spokeswoman Ena Von Baer.

More than 60 thousand people gathered on Plaza de la Ciudadanía (Citizen’s Square) in Santiago to celebrate the Bicentennial. There was a projection of historical images that also contained a message from the trapped miners in Copiapó. A giant flag of Chile (18 meters of height, 27 of width; weighing 200 kilograms) was raised on the square on Friday morning.

Celebrations of the Bicentennial in Pichilemu started earlier this month. On September 2, two thousand people lined up in a formation to create the message “Viva Chile Bicentenario Cardenal Caro” on Pichilemu beach “Las Terrazas”. The message was used to create a postal stamp to be released worldwide. The event was promoted by the Government of Cardenal Caro Province.

Private schools in the city, such as Colegio Preciosa Sangre, prepared events specially for their students. On Thursday, “Fonda Don Vicente Nario” was opened on Preciosa Sangre. Several games were performed there on that morning, including “el emboque”, “ponerle la cola al burro” (to put the tail to the donkey), and others.

Another event on Preciosa Sangre took place on Thursday night, when students recreated scenes of the History of Chile, including: a tertulia featuring Manuel Montt (starred by Luis Rojas); a chingana (a popular tavern); and selected colonial professions, such as the “motero” (person who sold motemei and chestnuts).

The official fonda of Pichilemu, La Bombonera, was inaugurated on Thursday night by Mayor Roberto Córdova, who danced cueca with people who attended the event. According to Córdova, at least 30,000 people have arrived at Pichilemu as of Friday, and it is estimated that another 30,000 will arrive during the next three days.

A great event took place on Pichilemu beach on Friday afternoon. Chilean typical games highlighted the event. People danced reggaeton, Américo’s cumbias and cuecas, while others were swimming. The National Shoe Fair (Feria Nacional del Calzado) was established on Agustín Ross Hotel on Thursday, and will stay in the town until September 23rd. Alicia Grez, who works on a kiosk in the Pichileminian Craft Fair located in front of One Discotheque, said that “sales have been excellent,” and that “[they] won’t miss the possibility to experience such an event like this.”
