Johnson Matthey

After the meeting last week in London, it is clear that the agreement on the new kilo not be achieved during the next meeting of the GFCM in October. The reason is the discrepancy between the two big experiments that have repesado per kilo depending on two constants. One is that Max Planck discovered in 1900 and the foundations of quantum physics. Another is the proposal by Amedeo Avogadro almost a century earlier to calculate the number of atoms in a gas based on your volume. Applied to the kilo, the proposals of both authors disagree. The exact magnitude of dissent is 0,00000017?, explains Mirandes Estefania, physical from Barcelona who works in the redefinition of the kilogram in the IBPM. This disagreement will be sufficient to delay the International Covenant until the next meeting of the CIPM, within four years.

Problems in the future there is a reasonable possibility that the new definition be adopted by 2015, but there is no certainty, explains Stock. Other three measures of the international system will have to wait until 2015 to be redefined: the mole, the ampere and the kelvin degree, something that don’t like all the experts involved. This issue could cause us problems in the future, confesses to this newspaper the physicist John Hall, an expert in the measurement of magnitudes by laser and winner of the Nobel in Physics in 2005. According to Hall, the redefinition may cause a disconnect with the past. The French weight was forged in London 131 years ago to reproduce as accurately called kilogram of the archives. It was a measurement equal to the weight of a liter of water which was set up by the Government of France in 1795, while the country waged a war against European powers that wanted to crush the revolution. The ampere, the kelvin and the Mole will be also reviewed the British company Johnson Matthey, still in operation, polished with great care a cylinder 39 mm high made of platinum for its weight reflects as much as possible to the liter of water.

Les Miserables In Concert

Music fans will surely know that this is a special year, as 2010 marks the 25th anniversary of Les Miserables, one of the main events of the tourism in London. And a way in which many are choosing the anniversary is visiting the capital and attending one of the many events that will take place in London. Those events include the special performance of the musical of Boublil & Schonberg, which will be conducted at the Barbican Centre from September 14 to October 2, 2010. This unique show will include participation of 2002 program Pop Idol runner-up Gareth Gates, who return to Marius in the story about his fiancee Collette and her stepfather Jean Valijean, a former inmate at the time of the French Revolution of the 19th century. Visitors may sit in the same seats that the first members of the public of Les Miserables used when the work, which later became the musical that longer takes representing, was premiered at the Barbican Theatre in 1985.

Therefore, while Les Miserables represent in theatres around the world, is expected that numerous visitors come to the British capital this month, since it’s where you started the legacy. Only 22 performances of the special work of Cameron Mackintosh carried out to mark the anniversary, which will have new scenarios, dressing rooms and a whole new team of production. In addition, those fans to the theater who are interested in something more can enjoy another type of anniversary celebrations: the concert special Les Miserables In Concert on October 3. It will take place at the famous O2 Arena Stadium, which is located next to the Thames, and, if you want to make the most of the occasion, can navigate to the stadium in boat.
