The new leadership of the European Space Agency (ESA) wants to build a permanent base on the Moon
.
according to information published in El País, the project will be developed at the European Astronaut Centre, based in the German city of Cologne.
“My intention is to build a permanent base on the moon a station open to different member states around the world “, said in a statement Jan Wörner, director of ESA.
the Agency believes that after the successful space mission Apollo is already possible” we take a giant step “in space history.
” we did in the sixties within ten years. So today with a much more developed technology, we are more than ready to get it again, “he said Andreas Mogensen, Agency astronaut.
Wörner said the lunar base will be part of a global project in which Americans, Russians, Chinese, Indians would include, Japanese “and even other countries with lower contributions”.
The European Space Agency (ESA) recently launched a satellite to examine the product of climate change variations, but its ambitions go far beyond focusing installing a permanent space base on the moon.
” my intention is to build a permanent base on the moon, an open station to different member states around the world, including Americans, Russians, Chinese, Indians, Japanese and even other countries with smaller contributions, “said Jan Wörner, director of ESA.
the aim of this project is that humanity can explore and exploit metals, minerals and ice water available in the natural satellite of the planet.
this ambitious plan is not easy as it runs the risk of cosmic solar radiation, micrometeorites and extreme temperatures. However, scientists and shuffle options to overcome these difficulties: “We can occupy floors moons to build radomes, build a structure or LEM habitable, we believe that can be made possible,” he said the Irish scientist Aidan Cowley
Cowley said the plan is to land a robot vehicle that inflates a dome as a basis to build the protective layer for astronauts to take shelter safely. However, ESA has indicated that it needed further 20 years at least so that the technology is ready to make it happen.
“This is a great development cycle that restart has to return to from the rockets that will lead to the orbit until the spacecraft carrying astronauts to the moon and help them land, “says Andreas Mogense, astronaut institution of the Old Continent.
The European Space Agency (ESA) not only wants to return to the moon, he wants to stay in it. The agency has announced its intention to build a permanent base on our natural satellite, the first ever lifted. The facility would be part of the global project of the International Space Station (ISS) and open to countries around the world who want to participate. The goal is that humanity can exploit the metals, minerals and ice water available on the moon. The European Astronaut Centre, based in the German city of Cologne, has already begun work on the ambitious project, which could take place in 20 years.
“My intention is to build a permanent base on Moon, open to different member states around the world station “, said Jan Wörner, director of ESA.” Were including Americans, Russians, Chinese, Indians, Japanese, and even other countries with lower contributions, “added.
the key message is to use the many resources available on satellite.” we have found ice at the lunar poles, and constantly exposed to daylight areas. These places can offer us the resources we need to build and sustain astronauts on the lunar base, “explains Bernard Foing, director of the International Group of Lunar Exploration.
the main threats to any lunar base are solar radiation and cosmic, micrometeorites and extreme temperatures. But the Irish scientist Cowley Aidan proposes to use the lunar soil itself to build radomes: “One of the ideas we came up with was that we could use this material in three dimensions to build a structure or habitable lunar module; and we believe it can be done, it is possible. Our concept is that a robot vehicle to land on the surface of the moon, and inflate a kind of inflatable dome as a basis to build the protective layer that will protect astronauts inside safely. “
“that is, a layer of dust, then a seal is placed, we will add another layer of powder on top and repeat the same operation until you have built any structure we want”, explains Cowley. Scientists look for places with rocks and similar dust to the lunar surface, such as volcanic park Eifel, near Cologne, to simulate lunar conditions.
Humanity has never been permanently on the moon, but the project leaders believe it is perfectly feasible and remember the Apollo missions, which showed in their time, with enough commitment, it is possible to take a giant step. “What we did in the sixties within ten years. So today with a much more developed technology, we are more than ready to get it back, “says Andreas Mogensen, ESA astronaut.
Just do not happen tomorrow. ESA recognizes that still need 20 years at least until the technology is ready to make this possible. “This is a great development cycle that has to restart again from the rockets that will lead to the orbit until the spacecraft carrying astronauts to the moon and help them land. And then, of course, the bases that remain on the moon. All this technology block must be put in place “Morgensen said.
The Chinese plan a mission to collect samples from the moon. Russia, meanwhile, is developing a robotic lander with the support of ESA, and the Orion capsule NASA should be flying around the moon before 2020.
In search of life Mars Without having to wait that long, this March the ExoMars mission will be launched to the red Planet for signs of methane. On board will take an instrument called NOMAD to analyze the composition of the Martian atmosphere, and methane in particular. “Methane is important because Earth has been linked to biological processes. There is not enough tangible evidence to be able to say whether there has been life on Mars, “explains Anne Carine Vandaele, one of the scientists responsible for the project.
Various instruments from different missions have measured and methane on Mars but there are still many questions unresolved in these measurements. ExoMars will try to clarify once and for all the problem of methane by using specific instruments for this gas
:: Samsung began to improve the quality of its materials and design, as Apple has been doing for years
NEW YORK.
Apple and Samsung follow closely each of its steps, their phones increasingly resemble more and after presentation of Galaxy S7 is almost impossible to tell them apart.
the convergence began two years when the iPhone ago became bigger , following in the footsteps of Samsung. Then Samsung began to improve the quality of its materials and design , as Apple has been doing for years. And recently Apple increased the resolution of the iPhone camera, shortening one of the gaps that most separated him from Samsung.
In S7, Samsung is reducing the resolution of your if camera, read welfare to reach 12 megapixels of iPhone .
Since since there are still some important differences. The last iPhone are the ones who give the possibility to activate certain functions by pressing stronger an icon or link, while Samsung is one of the main promoters of virtual reality.
it is too early to say which of the new models is better. Samsung presented the S7 Sunday at a fair in Barcelona, but the device will not go on sale until March 11.
It is likely that most users decreeing one tie. Samsung is the leader among Android and Apple uses its own ecosystem, iOS phones. For many, the choice depends on the system you like most and applications available for each.
What is known so far of the new models of Apple Samsung
cAMERA
in both the rear camera now has 12 megapixels (the iPhone rose from 8 to 12 and Samsung dropped from 18 to 12 ). This does not mean that Samsung worse.
To make the change, Samsung adopted dimension 4 × 3 iPhone, putting aside the widescreen format that using and producing images so elongated that one had to reduce to 4 × 3 anyway. In practice, the reduction of 6 megapixels offset this deficit and improves image.
The front cameras have both 5 megapixels since Apple improved the resolution of the iPhone in the middle of last year. Apple allowed the same screen use a flash for selfies and Samsung is doing the same with the S7.
Samsung promises to improve distance shots in low light, incorporating techniques SLRs, though this step will require a lot of experimentation. In last year’s models Samsung cameras tended to produce brighter than the iPhone shots. But also more distortions when the image is enlarged. It remains to be seen if it has been corrected in S7.
SIZE
Galaxy S7 Samsung is nearly 13 centimeters (5.1 inches) and is slightly larger and heavier than iPhone 6 (12 cm or 4.7 inches), but not much. The S7 Edge , a more refined version has curved screen edges, like a waterfall. Edge screen is 14 cm (5.5 inches), but this is due to the curvature. The phone is slightly wider and heavier.
Compared to the iPhone 6s Plus 14 cm, however, the S7 Edge is smaller.
EXTRAS
neither the iPhone nor allow S7 replace the battery . But the S7 can add memory. And the basic model is 32 gigabytes, double that of the iPhone.
Unlike the iPhone , on the other hand, the S7 is waterproof. And it does not cover the ports. The S7 also allows wireless charging. Just posing the appliance on a base. The burden, however, is slower than a cable.
Apple and Samsung allow unlock the device with fingerprints, without a security code. And both can make payments with a touch on some business.
SHORTCUTS
The latest models of iPhone and S7 Edge have shortcuts to a number of functions, including selfies. With the iPhone you have to press a hard icon. With the Edge you can slide your finger along the right side and access to holders, contacts and favorite applications is achieved.
Apple allows outsiders create your own shortcuts, Samsung not.
dISPLAY
One of the differences that persist screen technology. While the iPhone and most other phones use LCD screens, Samsung uses AMOLED , which has more vivid colors, although sometimes appear unnatural. Individual pixels produce their own light, without wasting energy. LCDs require energy to light when it is dark.
In practice, the S7 Samsung always shows the time, notifications and other things being “off” or locked.
VIRTUAL REALITY
in this field, Samsung will take advantage Apple , but faces competition from other manufacturers such as LG.
Samsung already has headphones RV and LG will bring soon as one. The two companies will be selling short-term cameras to capture 360 degree video in RV. Mobile applications facilitate sharing and see RV video
The new leadership of the European Space Agency (ESA) wants to build a permanent base on the moon, where half a century ago the Russians first arrived and Americans took their first steps. It is a “very ambitious” project that is already working the European Astronaut Centre based in the German city of Cologne.
“My intention is to build a permanent base on the moon, a station open to different member states around the world, “says Jan Wörner, director of the ESA, in a statement released today by the Agency.
humanity has never been permanently on our satellite, but Apollo space mission showed in his time “that with enough commitment, it is possible to take a giant step,” says ESA. “We did in the sixties within ten years. So today with a much more developed technology, we are more than ready to get back,” says Andreas Mogensen, ESA astronaut.
the idea is that the lunar base part of the overall project of the International Space Station, where they would be included Americans, Russians, Chinese, Indians, Japanese “and even other countries with lower contributions” adds Jan Wörner .
A workshop with details
earlier this month, the European Astronaut Centre in Cologne organized a workshop on how to build a permanent lunar people. The key message is that humanity can use metals, minerals and ice water available on the moon.
“The Moon is full of resources. We found ice at the lunar poles, and we found exposed areas constantly in the light of day. These places can offer us the resources we need to build and sustain astronauts on the lunar base, “says Bernard Foing, director of the International Group of Lunar Exploration.
main threats to any lunar base are solar and cosmic radiation, micrometeorites and extreme temperatures. But the Irish scientist Aidan Cowley explained at the workshop how you can use the lunar soil itself to build radomes.
“One of the ideas we came up with was that we could use this material in three dimensions to build a structure or habitable lunar module, and we believe it can be done, it is possible. Our concept is that a robot vehicle to land on the surface of the Moon, inflate a kind of inflatable dome as a basis to build the protective layer that protect astronauts inside safely. that is, a layer of dust, then a seal is placed, we will add another layer of powder on top and repeat the same operation until you have built any structure we want, “he continues detailing Cowley.
as it is not easy to go to the moon to implement new ideas, scientists look for places with rocks and similar to this satellite dust, such as volcanic Eifel park near Cologne. “Here we have the equipment and tools we need to measure the composition of rocks. And to assess their actual performance, we use rocks with similar characteristics to lunar and Martian rocks, ie volcanic rocks,” says Bernard Foing.
“My intention is to build a permanent base on the moon a station open to different members around the world states, “says Jan Wörner, ESA Director
” in this simulation I am the astronaut. My colleague has guided me to the particular place where she wanted to draw some samples. Then he asked me to return to examine the sample taken in front of this small laboratory, “says Oscar Kamps, geology student at the University of Utrecht.
20 years ahead
experts believe, however, that still need 20 years at least until the technology is ready to make it happen.
“This is a great development cycle that restart has to return to from the rockets that will lead to orbit until ships space carrying astronauts to the moon and help them land. And then, of course, the bases remain there. All this technology block must be put in place, “explains Andreas Mogensen, astronaut, ESA.
China plans a mission to collect samples from the moon. Russia, meanwhile, is developing a module robotic landing with the support of ESA and NASA Orion capsule should be flying around the moon before 2020. This diversity is key, segúne Jan Wörner:
the Moon is full of resources. we found ice at the lunar poles, and we found exposed areas constantly to light day
“One of the advantages of our idea of a lunar village is that it requires a large initial funding. That is, we can start with a small landing mission, that many countries are already planning, to a large investment, such as some telescopes, a radio telescope on the far side of the moon. So you will have multiple uses for multiple users, but in one place, “concludes Wörner
MEXICO CITY (CNNExpansión) – If you are still those who are reluctant to abandon operating systems Blackberry and Nokia Lumia, instant messaging WhatsApp you have bad news: cease to provide the service.
The decision is that the platform seeks to “focus its efforts on mobile platforms that most people use,” said the application through a statement on his blog last Friday.
Among the mobile platforms that will no longer have the application are BlackBerry 10, Nokia S40, Nokia Symbian S60, Android 2.1, Android 2.2 and Windows Phone 7.
“Although these devices phones have been an important part of our history, do not offer the kind of capabilities we need to extend the application in the future, “explained WhatsApp.
Read:? When I awoke the first thing you see is WhatsApp
app said that in 2009, when it was launched the messaging platform, the use of mobile devices was very different from today.
“About 70% of smart phones sold at that time had operating systems offered by BlackBerry and Nokia” now mobile operating systems offered by Google, Apple and Microsoft accounted for 99.5% of users WhatsApp.
The company recommended to update the application with a version of Android, iPhone or Windows Phone before the end of 2016 to continue using the service WhatsApp.
More than 1,000 million people ‘whatsappean’ with this service, said Jan Koum, founder of the company, in early February. Ie one of every seven people on earth use the service that Facebook acquired in 2014.
Users send around 42,000 messages a day, share 1,600 million photos and 250 million videos added Koum .
The new plate can be purchased at a price of $ 35.
The Raspberry Pi 3 has already gone on sale. The new board model designed by the British company costs $ 35 (about 32 euros, the same price as the Raspberry Pi 2) and incorporates several new features listed on the official website of the company ( in English).
The Raspberry Pi 3 features an ARM Cortex-A53 processor 1.2GHz eight-core, about ten times higher than that presented the first Raspberry Pi. But the main novelty is that this new model has a WiFi 802.11n and Bluetooth 4.1 connectivity connection, which is an improvement over previous versions, which only incorporated an Ethernet port. Indeed, the British company it has also clarified that the connectivity between these two models and the Raspberry Pi 3 is guaranteed.
As a curiosity, it should be noted that the Raspberry Pi 3 has begun marketing just Four years after the release of the first version, which since 2012 has sold about five million units to which must be added another three million sales Raspberry Pi 2 whose exit the market only a year ago. Raspberry has confirmed that these two previous models will not be recalled.
Today, February 26, 2016, a year which was one of the biggest is true hits viral Internet, “of what color is this dress Blue and black or white and gold ?. and BuzzFeed exploded in a week reached 73 million page views Insane Now BuzzFeed repeated with Adidas garment?… ¿white blue, brown and black, or green and gold? Genius .
the sense of sight enables us to see the world around us, but the real organ of vision are not eyes, but the brain. from what we see, the mind is responsible for extracting the most relevant information, filling in the “gaps” and “data” that lacks the knowledge gained by experience. As we explained Luis M. Martinez, the Institute of Neurosciences of Alicante, “our brain is designed to filter very little information that reaches the retina.” in the case of color perception, this is further modified depending on the daylight.
in other words, depending on the time of day in which we are, the color varies shaft of light red dawn and dusk blue-white noon . Therefore the mind must discard that “color bias” of light to perceive color of the dress or garment BuzzFeed. “If you drop the blue end watching white and gold dress,” noted a year ago Bevil Conway, a neuroscientist at Wellesley College. Conversely, if you dismiss the gold and green of the garment of BuzzFeed, perceive blue and white colors of this piece of clothing.
One person, however, will see the same colors throughout the day because, according to Martinez, “our brain has mechanisms for visual perception is as constant as possible.” But observation of the garment will also change according to age and sex. Women, for example, tend to see a greater variety of colors than men. And even the “visual training” helps improve this perception and the way we observe the dress or garment. What colors do you see it?
Bees, birds, butterflies and beetles are part of a growing list of pollinator species that are in danger of extinction in the world, says a study by the United Nations.
That trend, warns the report, could threaten the food supply in the world.
pollinators contribute significantly to the global production of food and nutrition security way, “said Vera Lucia Imperatriz-Fonseca , co-chair of Evaluation and catedrática of the University of Sao Paulo, in a statement.
“Your health HATH directly linked to our own welfare.”
That includes our well-being financial: approximately 235,000 to 577,000 million dollars in global crop they could be affected each year ± or because, according to the study, almost 16% of vertebrate pollinators in the world currently under-way to extinction
.
the plants with wild flowers are those that are most at risk. The researchers say that nearly 90% of them depend on the pollination of animals to some extent.
The wild pollinators are declining
Several factors may be causing the decline of the species , the study authors said.
“the wild pollinators in certain regions, especially bees and butterflies, They’re being threatened by a variety of factors,” said Sir Robert Watson, vice president of IPBES.
“the decrease is mainly to changes in land use, the agrÃcolas intensive practices and pesticide use, invasive alien species, diseases, pests, and change climático “it added Watson.
not everything is pessimism
the Evaluation unprecedented pollinators tardó two-year ± os to complete, and a team of 77 experts from around the world pored over 3,000 scientific articles to prepare the report, which was presented Friday at Kuala Lumpur, Malaysia.
But not all doom and gloom.
“the good news is that you can take several steps to reduce risks to pollinators, including practices based in indÃgena and local knowledge “, the founder of IPBES president.
he said in a statement Zakri Abdul Hamid the study incluyó information on these practices and information from 60 locations around the world.
Some of these measures are used sustainable agriculture, diversify crops and production ecológica food, actions that could ensure that the story of the birds and the bees is part of many generations in the future.
The Space Agency (NASA) has spread an image that you can see the canyons of the north pole of Pluto, the dwarf planet has been photographed by the spacecraft New Horizons.
photography reveals in detail long ice cannons crossing vertically Lowell Regio, an area named after the American estrónomo Percival Lowell who contributed to the discovery of Pluto.
Pictured is indicated by yellow barrel more large, measuring 74 kilometers wide and has a shallow valley shown in blue. Green, other parallel canyons, which are 10 kilometers wide is.
Because of their status, scientists believe it has much older than the guns of other parts of the dwarf planet, with sharper contours.
in pink can be seen another irregular cannon on its extension. To the right of the image, in red, holes that reach 70 kilometers in diameter and 4 deep shown.
According to experts, these pits could be places of melting deposited beneath ice that brought down the floor.
the image was obtained by the multispectral camera Ralph Ne w Horizons. It has an image resolution of about 680 meters per each pixel. The lower edge of the image represents approximately 1,200 kilometers, detailing the NASA on its official website.
The photograph was obtained at about 33,900 kilometers from Pluto, 45 minutes before the maximum approach between the planet and the New Horizons probe on July 14, 2015.
At the Geneva Motor Show, Alfa Romeo will present the 2016 version of the Giulietta, its classic five-door hatchback. The update is mainly based on slight aesthetic touches , a restructuring of versions and a new combination of engine and transmission.
On the outside, the changes are in the new alloy wheels (can be 17, 18 or 19 inches), on the grill, the front bumper, headlights and rear exhaust outlets. In addition, the logo “Giulietta” switched places in the trunk and has new typography. Inside, the Uconnect system added with a touch screen 5-inch or 6.5 , depending on the version.
The versions of the new Giulietta are three: Giulietta, Giulietta Veloce Super and Giulietta. The latter replaces the famous Quadrifoglio Verde option Brembo brake system, leather upholstery, sports suspension , different bumper design and side skirts.
The available engines remain Seven: Four gasoline engines and three diesel 120 to 240 hp. The novelty is that the 1.6 diesel 120 hp variant can now be combined with the automatic transmission and six-speed dual clutch.
Salteño Marcos Ramirez says that since man became interested in astronomy and always liked mathematics. Curiosity led him to take courses at the National University of Salta (UNSA) while in high school. Marcos vocation was defined before starting the stage of the faculty. Now holds a degree in physics and a doctorate in general relativity. He works as a postdoctoral fellow Conicet at the Faculty of Mathematics, Astronomy and Physics (FaMAF) of the National University of Cordoba, where they reside but soon leave. In a few months he will return to his native land to start new work because it was appointed assistant researcher at CONICET in UNSa. After verification of the existence of gravitational waves, Albert Einstein predicted those 100 years ago, physicists are more than excited. “This allows us to observe very violent cosmos events that occur within seconds or minutes that had no access before, such as collision and merger of two black holes. This is precisely what was observed,” said the researcher. What are gravitational waves? How would you describe them?
According to Einstein’s general relativity, space and time are two aspects of the same entity, which we call space-time, which it is the set of all places and all times where things happened, happen and will happen. Gravitational waves are disturbances of the geometry of this space-time that spread from one place to another at the speed of light. If space-time outside the surface of a pond, these waves would be like small waves traveling through this area; They are like small wrinkles travelers the very structure of space. If we were observing a crossed by one of these waves object, and if it is strong enough, we would observe that it is deformed in an oscillating manner: stretch it in one direction and then in another perpendicular to the first, successively, as the wave pass. We could also think of them as small vibrations from the cosmos that affect everything they cross, something like music of the stars. carry energy?
Like any wave transports energy through space. In principle the same are generated all the time. Almost any massive object in motion generate, including our bodies, but in general the energy they carry is so small that its effect is absolutely negligible. They are an important factor only in certain astronomical events involving the formation of a collision, much more massive than our sun, or in the early stages of the universe very massive objects. With the detection of such waves is said to have opened a new era in cosmology, why?
More than the opening of a new era in cosmology, which is possible but is not sure that is the inauguration of a whole new branch of astronomy .: gravitational wave astronomy Almost everything we know about the universe, so far, it comes from the light that reaches us; light in the broad sense. What our eyes perceive is only a small portion of the so-called electromagnetic spectrum that includes X-rays, ultraviolet, infrared and radio waves. Gravitational radiation detectors are new eyes to observe the cosmos, which could fundamentally change our conception of the universe. Observing these waves can know details of black holes and neutron stars, objects still quite mysterious. It allows us to observe the cosmos very violent events that occur within seconds or minutes, which we had no access before, such as collision and merger of two black holes. Why LIGO was built, the building to detect them? This discovery, will impact our daily lives? LIGO (by the acronym Observatory Laser Interferometer Gravitational Wave) is a pair of giant interferometers located 3,000 kilometers apart, in opposite points of the United States. Each of these interferometers an array of mirrors is L-shaped, with arms 4 kilometers, within ducts where an almost perfect vacuum, through which pass laser light beams is maintained. The instrument is sensitive to small changes in the distance between the mirrors, even minor shifts detects the size of an atomic nucleus. building something sophisticated proved necessary to detect these waves, because even in the most intense events, the effect they would have on earth is incredibly small. Is that these events often occur hundreds or billions of light years away. From the scientific, predicting the existence of gravitational waves was always one of the big bills pending in the observational test of general relativity . For those who are dedicated to this branch of physics it seems essential to because it gives us confidence in our understanding of the universe and allows us to explore objects and phenomena that we were invisible before. It is known that for governments to fund experiments on this scale, pure knowledge is never sufficient reason. In this, as in others which are invested hundreds of millions of dollars, the investment is mostly in technological development. It is about building a single device, innovative, involving engineering challenges. It is the resolution of these challenges which can bring a benefit to the community. It is very difficult to know how these developments will impact on everyday life, perhaps take decades until we know Dr. Gabriela González is Argentina and was the spokeswoman of this discovery, but the project hundreds of scientists participated. What was the collaboration of Argentina in the LIGO project? Gabriela González is a graduate of the Faculty where I currently work, the Faculty of Mathematics, Astronomy and Physics (FaMAF) of the National University of Cordoba. Here there is a research group devoted to the study of the theory of relativity and has close links with other groups directly involved in the development of LIGO, including Louisiana State University (where Gabriela Gonzalez works) and the University of Texas at Brownsville (where Mario Diaz works, graduated from the FaMAF). While no academic institution Argentina participated in the construction and operation of LIGO, several researchers in the country that contributed to modeling astrophysical processes that generate these waves, which is critical for data analysis. With the appointment of Conicet at the National University of Salta, what kind of research will face here? In September last year left the resolution designating me as an assistant researcher at CONICET, ie, in the first ranks as plant scientist. The proposed work plan has to do with theories involving many dimensions, more specifically to the study of potentially observable cosmological scale of the existence of extra dimensions consequences. It is purely theoretical research, and while it is within the framework of Einstein’s relativity, in my work proposal also intend to study other more general theories. Still no appointment became effective. You may leave in April, but is not sure. In the community there are rumors that, with the change of government, the appointment will take longer than usual. What was it that caught his interest in physics in the workshop professor Daniel Cordoba dictates? From childhood I was interested in astronomy and I always liked mathematics. Curiosity led me to take courses at the university. I think my vocation was already defined before starting the secondary. I discovered that what I was interested in astronomy was actually physics, the fundamental principles that help us understand the universe. And in the workshop of Daniel I learned, above all, to solve problems, and deepen many concepts.
in Salta Puna
in the Salta Puna there, near Tolar Grande, the robotic telescope Toros, recently built and implemented by the IATE (Institute of Theoretical Astronomy and Experimental, under the Conicet and UNC) and the University of Texas at Brownsville.
This is a place with excellent viewing conditions in the Macón hill.
This telescope is part of a network of computers that help detect the “visible counterpart” of events gravitational radiation emission. That is, are telescopes in different parts of the world in constant communication with receivers LIGO pointing to a particular region of the sky, well there are warning detection of gravitational waves. What is observed in this region of the sky at the time can give very important information about the event happened. This is another form of local cooperation.
About Marcos Ramirez
Data sheet
His specialty is general relativity. He completed his doctorate in the area at the Faculty of Mathematics, Astronomy and Physics (FaMAF) of the National University of Cordoba in 2012. He worked on the stability of exact solutions of Einstein’s equations, which have to do with their suitability to different systems astrophysical and cosmological. “It’s a very technical work, bordering on mathematical physics. Two of my works have to do with gravitational waves,” said the scientist.
The founder of Facebook, Mark Zuckerberg, said your social network needs to take stronger measures against “hate speech towards migrants”.
Zuckerberg, who visited on Friday the German capital during a meeting with Chancellor Angela Merkel and his chief of staff, offered a public conference in Berlin, which were invited about 1,000 people, in which he identified himself migrants as a group that needs protection.
precisely in Germany, Facebook was recently criticized for failing to react more strongly to certain racist publications and anti-immigration content.
the tensions around immigration crisis have intensified in Germany and in other European countries in recent months.
But the debate now moves to the digital plane.
A “change of approach”
Protests against migrants increased in some parts of Europe
According to the Minister of justice of Germany, Facebook acts quickly to remove images of sexual content to do with racist messages.
in January, it was reported that the authorities German were working on a deal with Facebook, Google and Twitter to ensure that laws take precedence over corporate policy.
When asked to clarify the position of Facebook in this regard, Zuckerberg said that “there is no place for that kind of content on Facebook or our community.”
“To learn more about German culture and its laws has allowed us to focus on changing the focus,” he said.
Zuckerberg did not specify how it intended to stop such material, but he said that “hate speech towards migrants were an important part of what we now have no tolerance Facebook”.
However, the founder of Facebook did say that part of the efforts consist of creating a team to work with the police to combat hate messages towards immigrants in their social network.
“We know that criris of migrants is a sensitive issue, and is something we are increasingly committed. There is still work to be done, “said the founder of the popular social network.
” we have heard the message loud and clear and are willing to do better, “he added
rising tensions
Groups anti-immigration protest in Germany before the arrival of migrants
Germany receives more refugees and asylum seekers than any other country in the European Union, many of them from war-torn countries, such as Syria.
the increase in the number of migrants entering the country coincides with increasing anti-immigration groups.
and meanwhile, tensions grow in Germany, on and off the Internet, especially after sexual assaults that took place during last New Year’s Eve, for which they are blamed, largely migrants.
in mid-January, the city of Landshut (in the region of Bavaria) sent to the headquarters German Chancellor in Berlin a bus with 31 asylum seekers, as an act of protest against its policy of welcoming migrants.
The debate is not only on the street, but also in social networks
.
And last week a hundred people took to the streets of the city of Clausnitz to protest shouting “we are the people”. They tried to block a bus they were traveling about 20 asylum seekers.
Two days later, an old hotel that was being converted into a shelter refugees was burned in Bautzen, too in the State of Saxony, Germany.
An angry mass cheered as the flames devoured the building. Some tried to impede the work of firefighters.
The building was to accommodate 300 asylum seekers from March and although no one was injured, the fire forced to change plans.
“inspiring model”
Currently, Germany is considering some proposals to toughen its immigration policy, especially after the attacks of New Year’s Eve.
And it is expected that companies argue if migrants could help provide labor.
Zuckerberg discussed the matter personally with Merkel last September and said he hoped the United States would follow the example of Germany, allowing more refugees in the country.
“the leadership of Germany in the refugee crisis has been inspiring and is a model for the world,” he said Zuckerberg.
The creator of Facebook said in a conference in Berlin on what actions to take if directed to the rival company. His surprising answer.
The creator of Facebook, Mark Zuckerberg, went through an awkward moment after a conference held in Berlin (Germany) was asked what actions it would take if directed . to the rival company Twitter
After thinking for a few moments, Mark Zuckerberg, the founder of the social network most used today, gave a surprising answer: “Let me answer that question talking about what we have Instagram made. Facebook has traditionally been more service focused on private communications with friends or small groups. One of the things that I think other networks, such as Twitter or YouTube, is that they have been more focused on its contents public. “
” Recently, with Instagram, and the same with Facebook, gave us realize that (the public content) is an area in the community we are building. People want to be in contact with athletes, celebrities, actors, politicians and civic leaders that interest them, “he said.
” Giving people tools to share what interests them, and to follow up these interests, I think that contributed greatly to the growth of Instagram. And I think historically, it has also served to Twitter to grow, “he said. ” But it is certainly an area where we focus with Instagram. When Instagram joined our company was a community of 20 million users, and the team working on Instagram was 14 people, “he explained at the conference in Berlin.
” By then, we all said ‘they bought it for 1,000 million dollars are crazy’. Since then, we enlarged ten times the team (150 staff of Facebook works best Instagram) and the community has grown from 20 million to 400 million. Today, it is bigger than Twitter, “he said.
” I think a lot of that is because we run a good map of situation in terms of giving people the ability to produce content in crude what’s going on in their lives, and he offered to ordinary people the ability to connect with it, “concluded
“To learn more about German culture and its laws has allowed us to focus on changing the focus,” he said. 
Currently, Germany is considering some proposals to toughen its immigration policy, especially after the attacks of New Year’s Eve.
