New blog design and Noosphere

This posting is celebrating the launch of the new design of the blog and website
(the picture above is digital art of Tatiana Plakhova).
Just as there are the biosphere, developed over millions of years around the terrestrial sphere, according to Teilhard de Chardin, the man emerged as a single species in the biosphere on Earth, breathing in a atmosphere, but subject to a kingdom “neither more nor less than a “sphere” – the Noosphere (or sphere thinking) about coextensively imposed-on (but the more connected and homogeneous) the Biosphere “(Chardin, 1997, p. 102).
Chardin describes the development of the Noosphere in two phases one occupation Biosphere, extension or as he calls it, where “swells in the first half of the path (to the equator [he thinks the poles to the center]) … a very similar pace, proceeds historically the establishment of the Noosphere “(Chardin, 1997, p. 103), and only lately … appearing in the World is the first symptoms folding definitive and global mass thinking inside a hemispherical top … “(Chardin, 1997, p. 104) and says that the first phase had three distinct characteristics:” Settlement, Civilization, Individualization “(idem).
This movement of contraction, which he called “planetarization” in raises “a fear reflected essential element before a whole, apparently blind, whose immense layers bend over it as if to absorb much alive … as Life, after lead us by the hand into the light, it dropped back, exhausted? “(Chardin, 1997, p. 126).
“From this point of view … no room in the eyes that our fears of ‘dehumanization by planetarization’ are exaggerated, because that planetarization that both frightens us is no more (judging by its effects) that the authentic and direct continuation of the evolutionary process that historically came out type human zoo? (Chardin, 1997, p. 127).
Chardin reaffirms his certainty that the complex “economic, technical, scientific and social” … “Behaves like a body that radiates, irradiation being formed by a free energy, the nature and transformations must be the subject of a brief study” (Chardin, 1997, p. 130).

NASA and Google unite to quantic computer

Quantum computers using the principles of quantum physics processing for modifying the torque current computers, and the binary bits 0 and 1 would use many more qubits values may, for example, using 7 photonic spectrum associated with qbits the light, the colors of the rainbow.
According to the Director of Engineering at Google, Hartmut Neven, the post that announced the establishment of a laboratory in collaboration with NASA: “We believe that quantum computing can help solve some of the most challenging issues of computer science, especially in terms of learning, “artificial Intelligence speaking, this is due to” learning machine is basically build better models of the world to make more accurate predictions. ”
But the problem is not just building the computer, more and more close to reality, there is still the problem of the creation of algorithms that can utilize these unique properties that provide basic information qubits is not only 0 and 1 .
Google says it is making progress in this direction, Neven said: “We have created a machine-learning algorithms quantum recognizers produces a very compact and efficient – very useful when you have little power of disposal, such as a mobile device.” That would be an immediate use of qubits.
The lab is building the D-Wave, but is based on a slightly different design of quantum computing with the adiabatic model, which is very different to the models of “doors” (gates) that the whole community that uses research the subject.
This leads many critics to skepticism of some critics, but college exams this week conducted at the University of Amherst shows that with certain tasks, a quantum computer lab worked fine.
