Deliberate Practice could only be helpful in developing expertise. It makes sense if you think about it; every expert I know has put in thousands of hours learning their craft. The ten-thousand hour rule indicates that it takes that much time to develop expert level proficiency; that's lots of deliberate practice.

Hong Kong: Hutchison increasing transmission ten-fold to 100G for business and consumer expansion | TeleGeography

Hong Kong fixed network operator Hutchison Global Communications (HGC) has launched a project to upgrade its entire fibre backbone infrastructure to increase transmission speeds to 100Gbps from 10Gbps to meet high bandwidth demand from business and residential users, and to support the launch of a range of new services in the second half of this year onwards.


HGC has set a capital expenditure budget of HKD700 million (USD90.2 million) for projects including completing the 100G network to enable it to deliver super high speed direct fibre-based multimedia content-based services to its whole footprint of more than 10,000 fibre-connected buildings and more than 1.6 million households.

 

The South China Morning Post reports that the 100G network will also serve as the infrastructure through which TVB Network Vision, the pay-TV business of free-to-air broadcaster Television Broadcasts, will transmit matches of the 2014 football World Cup in ultra high-definition.

 

Byron Chiang Yung-hon, HGC’s technology director, said the network will allow more than a million TVB subscribers to watch World Cup matches in ultra HD, and Raymond Ho Wai-ming, consumer market director at HGC, said the company was keen to promote video-on-demand programming from third-party content providers like TVB to the households that it covers with direct fibre connections.

Speed of light and other natural constants are indications of the total number of elementary particles in nature

Speed of light and other natural constants are indications of the total number of elementary particles in nature | JOIN SCOOP.IT AND FOLLOW ME ON SCOOP.IT | Scoop.it

A quantum level mechanism for interpreting vacuum as being filled with pairs of virtual particles with fluctuating energy values has been identified by scientists at the University of Paris-Sud, France, meaning that the inherent characteristics of vacuum, like the speed of light, may not be a constant after all, but fluctuate.

 

This research comes at the same time as a study conducted at the Max Planck Institute for the Physics of Light in Erlangen, Germany, suggest that physical constants, such as the speed of light and the so called impedance of free space, are indications of the total number of elementary particles in nature.

 

When observed at the quantum level, vacuum is not empty. It is filled with continuously appearing and disappearing particle pairs such as electron-positron or quark-antiquark pairs. These ephemeral particles are real particles, but their lifetimes are extremely short.

 

In the French study, Professor Marcel Urban and colleagues established, for the first time, a detailed quantum mechanism that would explain the magnetisation and polarisation of the vacuum, referred to as vacuum permeability and permittivity, and the finite speed of light. This finding is relevant because it suggests the existence of a limited number of ephemeral particles per unit volume in a vacuum. As a result, there is a theoretical possibility that the speed of light is not fixed, as conventional physics has assumed.

 

Instead, they argue, it could fluctuate at a level independent of the energy of each light quantum, or photon, and greater than fluctuations induced by quantum level gravity. The speed of light would thus be dependent on variations in the vacuum properties of space or time. The fluctuations of the photon propagation time are estimated to be on the order of 50 attoseconds per square metre of crossed vacuum, which might be testable with the help of new ultra-fast lasers.

 

The German study, meanwhile, led by Professors Gerd Leuchs and Luis L Sánchez-Soto, modelled virtual charged particle pairs as electric dipoles responsible for the polarisation of the vacuum. They found that a specific property of vacuum called the impedance, which is crucial to determining the speed of light, depends only on the sum of the square of the electric charges of particles but not on their masses.

 

If this is proved to be correct, the value of the speed of light combined with the value of vacuum impedance gives an indication of the total number of charged elementary particles existing in nature. Experimental results support this hypothesis.

MIT Creates ‘Plug-and-Play’ CO2 Scrubber for Existing Power Plants

MIT Creates ‘Plug-and-Play’ CO2 Scrubber for Existing Power Plants | JOIN SCOOP.IT AND FOLLOW ME ON SCOOP.IT | Scoop.it

MIT researchers have invented a “plug-and-play” carbon dioxide scrubbing system that they say could be added relatively easily to any existing power plant, and uses less power than existing systems.

Most existing systems rely on complex plumbing to divert the steam used to drive the turbines that generate power in these plants. Such systems are not practical as retrofits to existing plants, MIT says. By contrast, the MIT system requires no steam connection and can operate at lower temperatures than other scrubbing technology.

 

The new electrochemical CO2 scrubber system is described in a paper published online in the journal Energy and Environmental Science, written by doctoral student Michael Stern, chemical engineering professor T. Alan Hatton and two others.

 

The system is a variation on a well-studied technology that uses chemical compounds called amines, which bind with CO2 in the plant’s emission stream and then release the gas when heated in a separate chamber. But the conventional process requires that almost half of the power plant’s low-pressure steam be diverted to provide the heat needed to force the amines to release the gas. That massive diversion would require such extensive changes to existing power plants that it is not considered economically feasible as a retrofit.

 

In the new system, an electrochemical process replaces the steam-based separation of amines and CO2. This system only requires electricity, so it can easily be added to an existing plant, researchers say.
