« The horizon is always discovered by the curious. »

—Jules Bercy

When I was a small child I always saw my Grandfather reading, out of curiosity I wanted to discover these desires which are in books. I fell in love with the book I never return and I would like to remain eternally in this inescapable love that gave me intellectual baggage. Every day I always wake up looking at all those that are happening all over the world but also in the universe.

War in Ukraine: which countries decided to send military aid to Kiev in the face of the Russian army?

« The Anti-War Coalition Works! » In a message posted on Twitter on Saturday morning, February 26, as the fighting reached Kiev , Ukrainian President Volodymyr Zelensky welcomed a telephone exchange with Emmanuel Macron. « Weapons and equipment sent by our partners are on their way to Ukraine » , still satisfied the head of state. If no nation has so far announced the sending of troops to help Ukraine against the Russian army, three days after the start of the invasion, several countries have made material resources available to Kiev.

The United States offers 350 million dollars of defensive equipment

The United States announced on Saturday the sending of new military aid to Ukraine in the amount of 350 million dollars (about 310.5 million euros). « This aid will include new defensive military assets that will enable Ukraine to combat the armored, airborne and other threats it faces today » , detailed the head of American diplomacy, Antony Blinken.

« This is another clear signal that the United States stands with the people of Ukraine as they defend their sovereign, courageous, and proud nation, » the secretary of state added. Antony Blinken recalled that the United States had released 60 million dollars (53.2 million euros) in military assistance to Ukraine in the fall, then 200 million (177.4 million euros) in more in December, « as the [Russian] threat materialized » .

With the 350 million announced on Saturday, « this brings to more than a billion dollars the total security assistance that the United States has granted to Ukraine during the past year » .

Germany delivers anti-tank rocket launchers

Germany had so far promised « 5,000 helmets » to the Ukrainian military, according to Der Spiegel . The German government announced on Saturday that it had authorized the delivery to Kiev of 1,000 anti-tank rocket launchers, 500 Stinger surface-to-air missiles and « several » howitzers, the government said.

This decision marks a political break. In Kiev, which criticized it for  not delivering arms, Germany argued that it had been its line since the post-war period: not to send lethal equipment to conflict zones. This position was however less and less tenable since the outbreak of the invasion of the country by the Russian army. « Russian aggression against Ukraine marks a change of era, it threatens the order established since the post-war period, » Chancellor Olaf Scholz said in a statement. « In this situation it is our duty to help Ukraine as much as we can to defend itself against the invading army of Vladimir Putin » .

Concretely, these deliveries of rocket launchers will be made by the Netherlands, and the howitzers by Estonia. These two countries had originally acquired this equipment from Germany and needed a green light from Berlin to be able to re-export it to Kiev.

Der Spiegel adds that « the shipment of 14 armored vehicles was approved on Saturday » , citing the Ministry of Economy. These vehicles can be used for the protection of personalities or for evacuations.

Czech Republic sends thousands of weapons

The Czech Republic has for its part announced that it will donate machine guns, automatic and precision rifles, pistols and ammunition to Ukraine, for a value of 7.6 million euros. « The government on Saturday approved additional aid to Ukraine which is facing a Russian attack , » Defense Minister Jana Cernochova said in a tweet on Saturday. « The Ministry of Defense will also take care of transportation to a place determined by the Ukrainian side. Our help is not over , » she added.

The minister then told reporters that these weapons would include 30,000 pistols, 7,000 assault rifles, 3,000 machine guns and several dozen sniper rifles as well as a million cartridges. This donation will be sent to Ukraine « within the next few hours » , she added. At the end of January, Prague had already approved a donation to Kiev of four thousand artillery shells worth 1.5 million euros which have yet to be delivered.

The Netherlands provides missiles and sniper rifles

« The Netherlands has very recently received additional requests for military equipment from Ukraine , » the Dutch Ministry of Defense confirmed in a letter to the Dutch parliament on Saturday. The country « will supply 200 Stinger anti-aircraft missiles to Ukraine as soon as possible » . “The planned delivery of military goods was and is intended for Ukrainian self-defense against armed attack from Russia ,” the letter said.

« The Ministry of Defense shipped some of the already promised goods on Saturday , » including sniper rifles and helmets, the ministry said, adding that « other goods will be shipped as soon as possible, but the Netherlands, as other countries, face logistical challenges » .

Italy helps with mine clearance

Italian Prime Minister Mario Draghi spoke to Volodymyr Zelensky on Saturday. « Our priority today must be to strengthen the security of our continent and to exert the greatest pressure on Russia to withdraw its troops and return to the negotiating table » , detailed the Italian government in a press release. released following a telephone conversation between the two leaders.

He also announced aid of 110 million euros to Ukraine « for humanitarian purposes and macro-financial stabilization » , as well as aid in military equipment « in particular in the sector of mine clearance and the supply of ‘protective equipment’ .

Belgium donates fuel and weapons

The Belgian Prime Minister for his part announced that his country would supply fuel and 2,000 machine guns to Kiev. « A more in-depth analysis of the requests continues » , added Alexander De Croo.

France strengthens its involvement on NATO’s eastern front

If the message published Saturday morning by President Volodymyr Zelensky on Twitter suggests that Emmanuel Macron raised the subject of material aid from France to Ukraine, Paris has not yet officially communicated to this topic.

In a text broadcast Friday evening, the President of the Republic however announced  » military reinforcements » of France within NATO. France has thus chosen to « accelerate and reinforce the already planned deployment of fighter planes in the Baltic States » . To these ends, « from mid-March, 4 Mirage 2000-5 supported by a hundred airmen will be deployed in Estonia. »

Emmanuel Macron also announced « punctually reinforcing the French system in Estonia » with a sub-group of around 200 soldiers who will be deployed « alongside our Danish and British allies. » It was also decided to accelerate the « deployment of capabilities in Romania within the framework of NATO » , with the presence of a combined arms tactical group of around 500 soldiers. « These military devices are not intended for any escalation, but simply to participate in the defense of the member countries of NATO » , justified in a second time the Ministry of the Armed Forces.

How will Mark Zuckerberg monetize the metaverse?

The Financial Times and Business Insider ‘s analysis  of dozens of patents recently granted to Facebook’s parent company reveals how Mark Zuckerberg plans to profit from our personal data in the metaverse.

Almost all the relevant patents contemplate wearing a helmet, glasses or even a headband to access the virtual world. They are equipped with technologies to track the gaze, the dilation of the pupils or the wrinkling of the nose – all signs of expression which will be exploited to generate income.

One of the patents in particular describes the analysis of eye tracking collected in a helmet by tiny cameras, in order to infer the interests of the user. For example, if his eyes linger on an image, it could indicate that he is interested in it and suddenly what he sees in the metaverse could change accordingly.

A patent studies how to personalize advertising in augmented reality, according to age, gender, areas of interest and « how users interact with social networks », in particular according to their likes and comments.

Another technology describes how to produce an ultra-realistic three-dimensional avatar, based on a person’s photo.

“Meta’s ambition is to be able to simulate every pore of the skin, every strand of hair, every micro-movement… In truth, they are undertaking a worldwide program of human cloning”, according to Noelle Martin, an activist -lawyer who has spent more than a year researching Meta’s ambitions, from Western University in Australia.

It seems obvious that Facebook is trying to create a much more realistic three-dimensional environment than the current version, where avatars represented as cartoon characters move awkwardly. The future metaverse will be populated by avatars able to move their eyes, change their expressions and adopt different postures with clothes that wrinkle with each movement. In this virtual environment, objects can be entered, moved and modified.

But Business Insider ‘s review of Meta’s patents has so far revealed no technology related to data protection, although Zuckerberg and other executives have insisted that the metaverse will be designed in this way. optical.

“It is very concerning that security and privacy are not present in patents,” said Owen Vaughan, director of research at nChain , a world leader in blockchain research and development. “They should be. Integrating them after the fact might prove impossible”.

What is 5G and how could it disrupt US aviation?

5G is the next generation of mobile internet connection. It allows people to download and upload data much faster, and more devices to access mobile internet at the same time.

To do this, it relies on an increased use of radio signals. In the United States, the radio frequencies used for 5G are in the part of the spectrum known as « C-band ».

These frequencies are close to those used by aircraft radio altimeters, which measure the height of the aircraft above the ground and also provide data for safety and navigation systems.

But interference from 5G transmissions could prevent these instruments from working properly and cause safety issues, especially when planes come in to land.

How serious is the risk to aircraft?

It is potentially very serious.

In late 2020, the RTCA – an American organization that produces technical guidance on aviation matters – issued a report warning of the possibility of “catastrophic failures resulting in multiple fatalities, in the absence of appropriate mitigating measures « .

More recently, the US aviation regulator, the FAA, warned that 5G interference could cause issues with a number of different systems on board Boeing’s 787 Dreamliner.

These issues could make it difficult to slow the aircraft on landing and cause it to drift off the runway.

How did water get to the Moon?

 In October 2020, NASA announced with great fanfare that water had been discovered on the Moon. Neither one nor two, the press then seized on this information, distorting it at the same time.

Because NASA’s discoveries were still only preliminary. On the ground, space missions had to confirm the theories and other analyzes of the American space agency. Finally, after more than a year of waiting for the scientific community, it is finally, ironically, the Chinese competitor (CNSA) which with its Chang’e 5 probe has provided NASA with the precious answer.

How the water came to our nocturnal star ?

Now that the presence of water on the surface of the Moon is no longer lacking (or almost), the big question is to know how this water could end up there. According to CNSA scientists who deliver their conclusions in an article published in the journal Science Advances, water would have arrived on the Moon because of the solar wind.

In fact, hydrogen particles traveled to the heart of this stellar wind before coming to rest on the Moon. Once deposited on the surface of our satellite, the hydrogen met the oxygen there, thus forming molecules of water (H2O) and hydroxyl (OH). This idea had already been developed by NASA researchers in 2018 and 2020 when the American space agency found traces of water on the Moon.

TikTok becomes most visited website, surpassing Google

The Chinese platform has gained six places in just one year, surpassing all services linked to Google.

With one billion monthly active users, TikTok is reaching a new milestone. The application of short videos overtakes Google and thus becomes the most visited website in the world in 2021, according to the ranking of the American company Cloudflare.

In other words, TikTok generates more traffic on its site than all of Google’s services combined: search engine, mapping, translation, news or photos. This is the first time that the ByteDance firm has climbed to the top of the charts.

After TikTok and Google, Facebook occupies the last place on the podium. Next are Microsoft, Apple , Amazon , Netflix , YouTube , Twitter and WhatsApp . This latest messaging app throws Instagram out of the Top 10, yet ninth in 2020. Compared to last year, Netflix has lost two places while Twitter has gained one. But this comparison should be taken with caution because the 2020 ranking began in September, so Cloudflare only analyzed the last four months of the year.

An « exquisitely preserved » embryo has been found inside a fossilised dinosaur egg.

An « exquisitely preserved » embryo has been found inside a fossilised dinosaur egg.

The discovery, dubbed « Baby Yingliang », is believed to be between 66 and 72 million years old, and was found in the Late Cretaceous rocks of Ganzhou, China.

Professor Steve Brusatte, part of the research team, said: « This dinosaur embryo inside its egg is one of the most beautiful fossils I have ever seen. » The embryo is believed to be a toothless theropod dinosaur, or oviraptorosaur – a group of feathered theropods, closely related to modern-day birds.

It’s official: China is now the richest country in the world

China has just overtaken the United States in the ranking of the richest countries on the planet, according to a report, now settling in first place.

China has just overtaken the United States in the ranking of the richest countries on the planet, according to a report, now settling in first place. The country’s value would have increased from $ 7 trillion in 2000 to over $ 120 trillion in 2020.

China goes ahead

The world has gotten much richer over the past two decades (net worth has tripled), but the distribution of wealth has shifted. Long behind the United States, China has just overtaken its main rival as the richest nation in the world. These are the two main lessons of a new report from the research arm of McKinsey & Co consultants, relayed by Bloomberg . For this work, the experts examined the national balance sheets of ten countries representing more than 60% of world income.

In detail, global net worth has grown from $ 156 trillion in 2000 to $ 514 trillion in 2020 , according to the report. China accounted for nearly a third of this development. The country’s wealth would thus have climbed from $ 7 trillion in 2000 to $ 120 trillion in 2020 . Its membership in the World Trade Organization in 2001 would obviously have accelerated this meteoric economic rise.

The United States, for its part, saw its net worth more than double over the period to reach $ 90 trillion in 2020. It should also be noted that in both the United States and China, more than two-thirds of wealth are owned by the richest 10% of households, and their share continues to increase.

According to the report, around 68% of that global net worth is stored in real estate. This sector includes machinery, infrastructure and equipment.

China widens the innovation gap

It should also be recalled that in 2019, China had overtaken the United States in the field of international patents with a thousand filings in advance. However, these applications filed through the WIPO Patent Cooperation Treaty (PCT) are one of the key indicators for measuring the various activities related to innovation.

In 2020, the Middle Kingdom retained its first place with 68,720 patents filed (+ 16% compared to 2019), ahead of the United States with its 59,230 filings (+ 3%). In other words, China remains in the lead, but also widens the gap on its direct competitor. Next come Japan, South Korea and Germany.

Donald Trump’s social network is already hacked!

Even before its launch, Trump was forced to shut down access to his social network  Truth Social . Internet users managed to register in his name and published a shower of insults as well as the same distasteful tweet  »  Pig Poop Balls   » dating from 2011.

What do we do when we can no longer access social networks? We throw his! After being banned from Twitter , Facebook and YouTube , Donald Trump announced his own site on Wednesday. Dubbed « Social Truth », it is part of a new Trump Media & Technology Group (TMTG) created to fight the  »  liberal media consortium   » and  »  resist the tyranny of the web giants  . »

In a few hours, Internet users, some of whom claim to be part of the Anonymous movement , had already discovered the address of the site when it was not yet officially launched. They then succeeded in creating accounts in the names of the former US president and several other personalities such as Steve Bannon (his former adviser), Mike Pence (his former vice-president), Ron Watkins (member of QAnon) or even the P .-Twitter CEO Jack Dorsey .

Troll festival and licensing issues

These fake accounts were then used to troll personalities and the site, between insults, conspiracy theories and images of a pig defecating on his testicles . The administrators first closed the creation of new accounts before having to disconnect the entire platform.

Others immediately realized that the site was a modified version of Mastodon, free software . The AGPLv3 license requires anyone who uses it to share their code and clearly display the license on the site. Of course, this was not done with Truth Social. The creator of Mastodon, Eugen Rochko, told the  Talking Points Memo site that he plans to find out about possible legal remedies. As expected, Trump’s site is off to a rocky start even before its launch …

America was discovered by the Vikings … 400 years before Christopher Columbus

It was from the north that the Vikings would have discovered America around the year 1000. Pixabay – gloverbh222

The doubt was allowed since archaeological discoveries of a few decades ago. Now it is a fact: the presence of the Vikings in North America has been confirmed … 400 years before the arrival of Christopher Columbus.

We will have to review all the textbooks and update all our certainties on the discovery of the Americas. Until now, history has taught schoolchildren around the world that Christopher Columbus, funded by Queen Isabella of Spain, discovered America in 1492 while exploring a new sea route to India through the Atlantic Ocean.

Since archaeological excavations dating back 50 years, there was doubt about the identity of the first Europeans to have set foot on American soil. Indeed, traces of Vikings had been spotted in northeastern Canada in particular thanks to wooden objects.null

But this time, there is no longer any doubt. A study published in the journal Nature by the University of Groningen (Netherlands) toured the world on Wednesday, October 20. It indicates that researchers found a way to confirm the presence of the Vikings in Newfoundland, 400 years before the arrival (much further south) of Christopher Columbus.

A decisive solar storm

And it is the sun that enlightened the researchers. This is because a solar storm dated to AD 993 released a huge pulse of radiation that was absorbed and stored by trees all over the Earth. It was this solar event that turned out to be decisive in determining the exact year the Vikings were present in the Americas.

Until now, the wooden elements recovered 50 years ago had been dated but with the radiocarbon technique the margin of error was about a century. But researchers at the time had recovered and preserved hundreds of other additional pieces of wood found on and around the site, storing many in freezers in a Canadian warehouse to prevent them from rotting. 

A stock which represented a « gold mine » for the archaeologist of the University of Groningen, Margot Kuitems, co-author of the study.

The thing that changed everything is that three of the wood samples were from living trees during the solar event of 993. The cosmic storm was so powerful that it embedded itself in the layers of trees around the world. , creating a kind of timestamp of these.

This phenomenon having only occurred twice during the last 2000 years, it was then « easier » to date the pieces of wood … and in particular the year of the felling of the tree by the Vikings which dates back to the 1000s. Christopher Columbus did not land in San Salvador until 1492 …
