Transdimensional Particles: Finding The 4th Dimension...

"A tantalizing idea considered since the early part of the last century is that the universe might have more than the three spatial dimensions of common experience.

In addition to the familiar left/right, back/forth and up/down, physicists have contemplated additional directions that are curled up to such a small size that they’ve so far eluded discovery.

For many years Einstein was a strong proponent of this idea. He had already shown that gravity was nothing but warps and curves in the familiar dimensions of space (and time); the new idea posited that nature’s other forces (for example, the electromagnetic force) amounted to warps and curves in additional, as yet unknown, spatial dimensions. Difficulties in applying the idea mathematically resulted in Einstein ultimately losing interest. But decades later, string theory revived it: the mathematics of string theory not only requires extra dimensions but has shown how to resolve the issues that flummoxed Einstein.

And now, remarkably, there’s a chance — albeit a small one — that the Large Hadron Collider may find evidence for the extra dimensions. Calculations show that some of the debris produced by the proton collisions may be ejected out of our familiar spatial dimensions and crammed into the others, a process we’d detect by an apparent loss of the energy the debris would carry.

The unknown is just how powerful the collisions need to be for this process to happen, a number itself determined by another unknown: just how small the extra dimensions, if they exist, actually are. The more tightly they’re curled, the harder it would be to cram anything in them and so the more energetic the required collisions.

Should the Large Hadron Collider have the power necessary to reveal extra dimensions of space — to overturn our belief that length, width and height are all there is — that would rank as one of the greatest upheavals in our understanding of the universe.

Finding what you don’t expect opens new vistas on the nature of reality. And that’s what humans, including those of us who happen to be physicists, live for."

Fritz Lang: Metropolis Rediscovered...

Last Tuesday Paula Félix-Didier traveled on a secret mission to Berlin in order to meet with three film experts. The museum director from Buenos Aires had something special in her luggage: a copy of a long version of Fritz Lang’s Metropolis, including scenes believed lost for almost 80 years. After examining the film the three experts are certain: The find from Buenos Aires is a real treasure, a worldwide sensation. Metropolis, the most important silent film in German history, can from this day on be considered to have been rediscovered.

Fritz Lang presented the original version of Metropolis in Berlin in January 1927. The film is set in the futuristic city of Metropolis, ruled by Joh Fredersen, whose workers live underground. His son falls in love with a young woman from the worker’s underworld – the conflict takes its course. At the time it was the most expensive German film ever made. It was intended to be a major offensive against Hollywood. However the film flopped with critics and audiences alike. Representatives of the American firm Paramount considerably shortened and re-edited the film. They oversimplified the plot, even cutting key scenes. The original version could only be seen in Berlin until May 1927 – from then on it was considered to have been lost forever.

Those recently viewing a restored version of the film first read the following insert: “More than a quarter of the film is believed to be lost forever.”

In 1928, Adolfo Z. Wilson, a man from Buenos Aires and head of the Terra film distribution company, arranged for a copy of the long version of “Metropolis” to be sent to Argentina to show it in cinemas there. Shortly afterwards a film critic called Manuel Peña Rodríguez came into possession of the reels and added them to his private collection. In the 1960s Peña Rodríguez sold the film reels to Argentina’s National Art Fund – clearly nobody had yet realized the value of the reels. A copy of these reels passed into the collection of the Museo del Cine (Cinema Museum) in Buenos Aires in 1992, the curatorship of which was taken over by Paula Félix-Didier in January this year. Her ex-husband, director of the film department of the Museum of Latin American Art, first entertained the decisive suspicion: He had heard from the manager of a cinema club, who years before had been surprised by how long a screening of this film had taken. Together, Paula Félix-Didier and her ex-husband took a look at the film in her archive – and discovered the missing scenes.

Among the footage that has now been discovered, according to the unanimous opinion of three experts, there are several scenes which are essential in order to understand the film: The role played by the actor Fritz Rasp in the film for instance, can finally be understood. Other scenes, such as for instance the saving of the children from the worker’s underworld, are considerably more dramatic. In brief: “Metropolis, Fritz Lang’s most famous film, can be seen through new eyes. The material believed to be lost leads to a new understanding of the Fritz Lang masterpiece.
