Science: China launches Telecom satellite

China successfully launched a satellite communications technology test late Thursday night.

The official Chinese news agency "Xinhua" said on Friday that the satellite was launched from the Xichang Launch Center in Sichuan Province.

"The satellite was launched at 23:18 by a Long March-3B carrier rocket," said the same source.

The Chinese Society of Aerospace Science and Technology [government] had previously claimed that Beijing aims to break a new record, launching 30 space shuttles in 2017.

Falling in love on the Internet, why not?

Seeking love on the Internet is one of those things that instantly cause rejection in many people. Why ? " The lack of romance " to some, while others will blame our friend the web of " lack spontaneity ." In a world that lives in the fast lane and where smartphones are grafted to all hands, why should we be ashamed to use a boost 2.0 to find footwear to our foot?

More precise research

When you type "Meet spouse ..." on Google , the first occurrence that appears is -on'll give you a thousand- "on the Internet." There is no wrong way to find love, as explained psychoanalyst Sophie Cadalen : "Under the pretext that everyone remains protected behind the screen, we tend to equate virtual falsehood, deception and denial Or fear of engaging. Except that in this virtual world, words meet.

And words count in a relationship, especially when it is nascent. But before the conversations (virtual then real) come the "match" between singles. And to find the one that corresponds to you, the sites and applications of encounters compete of ingenuity with (almost) perfect algorithms. Do you prefer your big half? Or do you have a low for small? What are your hobbies ? Your taste in ice cream ... In short, anything that can help these specialists to determine a profile 2.0 is good to take!

Not really a blind date ...

When the virtual wall falls and the first appointment in the flesh finally takes place, it is often panic. But frankly, what first appointment is free of stress? No. The advantage of a first date with someone we met online is that we already know each other. After spending hours talking through a screen, it is much easier to find a topic of conversation.

The evolution of morals

Mamie Giselle may have met Papi Raymond at the village ball in 1956 but that is no reason to imitate him. And then, at the time of our ancestors, the parents (and sometimes even the whole family) had their say. Not easy to make one's own choice. Today, the fact that our half pleases our parents is important, but this is not our main argument when we embark on a story.

The new generation is looking for something valuable: emancipation. The parents, but also the company that is urgent as soon as we passed the fateful 30 years . So, not yet married? When are you gonna bring us somebody? And the children, did you think about it? All these incessant and unpleasant questions are missed when one is behind his computer screen or smartphone. In the shelter, one can also indulge in virtual interactions without pressure .

Diversity and tolerance

When we meet someone through a friend, a colleague or a member of our family, we inevitably evolve in the same circles. Same conversations, same taste, same origins ... If it looks like we reassures us, it can also quickly become boring. 

The advantage of virtual encounters is that the person can be thousands of miles away and in a few clicks it is closer to you than your next-door neighbour. We discover different habits, desires and tastes that are not ours but that enrich us. And if it does not fit between you and your virtual friend, you can cut off the discussion without risking getting angry with the person who presented you ...

There is something for every taste

Exit the minitel, at the forefront of the trend, we all have in the pocket a smartphone that chirps. And since you are hooked to this little jewel all holy day, download one of these applications that are all the rage in recent months. Happen, Tinder and others allow you to connect with those who are in your area. Some likes later, here you are launched ... 

You doubted relationships 2.0? Maybe these few lines will allow you to take the plunge! And do not forget one thing: you lose absolutely nothing to try ... So, tempted?

Physics: Physicists detect a particle that is its own antiparticle

Using a copper wire width of an atom only, physicists from Princeton University have managed to show a particle predicted in 1937, but had never been observed until now for sure: the particle Majorana (see red area in the zoomed portion of the image). Credits: Yazdani Lab, Princeton University

A particle that is also its own antiparticle? This is known Majorana particle. Predicted in 1937, it has first to be detected by physicists from Princeton University (USA).
Physicists detected for the first time the existence of a said Majorana particle. Majorana particle? Predicted in 1937 by the Italian physicist Ettore Majorana, a Majorana particle is both matter and antimatter ....

Let us briefly recall what antimatter. The particles of antimatter have the same mass as their equivalent material but carry an opposite charge. For example, the positron, positively charged, is the antiparticle of the electron, negatively charged. Particulate matter and antimatter are always produced together, as a pair. Yet around us is almost exclusively composed of matter, which suggests that during the evolution of the Universe, very large quantities of antimatter have been "lost" (read more about antimatter, read this article extension antimatter published on the CERN site)

In practice this means that the particle Majorana is electrically neutral, since combining opposite charges (the charge of the particle, and the burden of the antiparticle, opposite to that of the particle). 

That said, let the circumstances of the discovery of this particle Majorana. To detect the physicist Ali Yazdani (Princeton University, USA) and colleagues have created a superconducting copper wire (Superconductivity is a phenomenon in which a material transports electricity with zero electrical resistance) off of an atom only. And it is by observing the end of the wire using a scanning tunnelling microscope that they discovered there the presence of Majorana particle.

Obviously, this methodology was not chosen at random: in 2001, the physicist Alexei Kitaev had indeed predicted that a Majorana particle would be likely to appear at the end of a superconducting wire. Where the methodology chosen by the authors of the new work.

Note that the discovery of this particle could lead to applications in quantum computers. Contrary to the "classical" computers, one of the essential principles of quantum computers based on the idea that an information unit may be worth while both 0 and 1 (corresponding to a state that physicists called "quantum superpositition"), which is obviously not the case in the binary system used by our computers, where an information unit can not argue that either of the two values ​​0 and 1.

This work was published October 2, 2014 in the journal Science, entitled "Observation of Majorana fermions in atomic chains ferromagnetic superconductor was".
