NASA captures the unusual trail of the “twin” tornadoes in Mississippi from space

by

If we look at the Mississippi from 700 kilometers above sea level, the landscape we usually see is a green carpet of forests and agricultural fields. However, last March this carpet was ‘torn’, as NASA could see through the Landsat 8 satellite. The images obtained revealed something extremely strange: “scars”, which are nothing more than traces of total destruction that reveal the trajectory of one of the most violent tornado outbreaks in the last decade. The surprising thing. It is not the magnitude of the damage that the passage of these could have generated. tornadoes down the Mississippi, but the geometry it has. And in Walthall County, satellites have immortalized an extremely rare phenomenon: two perfectly parallel scars. Something that represents a “mute” testimony of two tornadoes that advanced hand in hand, wreaking chaos. Paths of destruction. The tornado outbreak in question occurred between March 14 and 16, 2025, and the truth is that it will be remembered for how aggressive it was. Specifically, data from NASA’s Earth Observatory and the National Weather Service (NWS) suggest that they were developed a total of 113 tornadoes in just three days, which affected 14 states. But it was precisely in Mississippi where the atmosphere decided to leave a unique visual signature. Landsat images show these two almost parallel tracks, like train tracks, near Tylertown. Your description. The first of these traces indicates that it arose due to the tornado EF4which had a journey of 90 km with estimated winds of 274 km/h. The second trace, which is shorter, but just as destructive, has a distance of 15 km, and was generated by a different tornado that followed an almost identical path. This phenomenon of “twin tornadoes” leaving parallel trails is a statistical rarity that allows meteorologists to study how supercells interact with each other under conditions of extreme instability. An ‘X’ of disaster. Not only were these parallel trails recorded in Mississippi, but in Covington County researchers they found also another quite unusual pattern: two scars that intersect almost at right angles forming a large ‘X’ over a wooded area. As if a great pirate treasure could be found underneath. And it was not a sensor error, since according to the data, two different tornadoes crossed their paths in an interval of just 40 minutes. For families in the area, it was a statistical nightmare: being hit by a natural disaster and, before an hour had passed, watching another large funnel pass through the rubble of what the first one had just destroyed. A violent 2025. This year’s March has certainly shattered weather records with a total of 299 tornadoes in a single month, and experts point to ‘The Girl‘ as responsible for all this. This climate phenomenon has altered the Pacific jet stream over North America, creating a perfect breeding ground for supercells! By moving the humidity of the Gulf of Mexico to the north and encountering very persistent cold air, everything necessary was in place to have a true meteorological war. And it is no wonder, since at least 1,000 homes were damaged by this phenomenon. Its usefulness. Beyond the photography of scars, science seeks to anticipate the disaster. Researchers at NASA Langley Research Center They are using these satellite images and data on cloud patterns to refine prediction models that allow the population to be warned with a little margin (but not much). The objective right now is to gain 10 minutes’ notice of tornado warnings so that the population can be protected. And it is no wonder, since a scenario where an EF4 can erase a neighborhood in seconds, having 600 extra seconds is the difference between life and death for those who find themselves in the path of this scar.

There are 10,000 soldiers and unusual artillery pointing at the same place in the Caribbean

by

It all started under the pretext of “drug trafficking”but the amount of accumulated signals, troops and artillery that the United States has been adding around the southern Caribbean, indicate that the operation has slipped towards a coercion mechanism strategic to force accelerated eviction without a formal invasion. A combination of visible deterrence, explicit threats and preparation of windows of surgical action. In the background: Venezuela. Evolution of the objective. It we count last week. The US deployment began wrapped in the classic language of the fight against drug trafficking, attacking boats fast and reactivating bases with a technical pretext. It happens that the accumulation of gestures (B-52 with transponders assets bordering on the Venezuelan FIR, “ghost ships”, SOF helicopters training off the coast, and the trump admission that “he doesn’t want to play”) seem to have another purpose: the message It no longer seems to deny drug routes, but rather something more akin to overthrowing the Venezuelan regime. The public articulation (“Maduro is a fugitive”, “he must go”) and privately aligns military deployment with a logic of collapse rather than containment. Artillery as pressure. The volume of resources and troops from Washington that CNN reported in the last few hours and the New York Times through satellite data (thousands of soldiers next to the ARG Iwo Jimathree destroyers DDG guided missilesa cruisea SSN submarineairplanes AC-130J armed with hellfire, F-35 in Puerto Ricoairplanes P-8, MQ-9, ISR flights massive and reactivation of the Roosevelt Roads base) is disproportionate to simply hunt down drug boats, although insufficient to occupy Caracas. Is, according to analystsexactly the size that allows hitting nodes (command, radars, escorts, inner rings) without “going fully into” a war, and maintaining a credible “low-profile” escalation vector. American voices match in the Financial Times: “it is too much for drug trafficking, but not enough for an invasion”, and what is left in the middle is a luck calibrated pressure. One of the satellite images captured on October 17 showing F-35 fighter jets at the José Aponte de la Torre Airport in Puerto Rico The mystery of Venezuela. For its part, the Venezuelan Armed Force is eroded by maintenance and spare parts, but much less naked: there is S-300anti-aircraft artillery, MANPADS, F-16 and a million militiamen that cast serious doubt on the reputational costs if Washington crosses the kinetic threshold. At the same time, the national commanders they suspect leaks and purge loyalties, the Times said that they sleep rotating locations and change escorts. A pattern that reveals internal vulnerability and expectation of a selective coup, in any case, there does not seem to be confidence in defeating the United States. Colombia and something more. The dialectical escalation with Colombia (Trump has called Petro a “drug leader,” threats of cut funds and tariffsand rhetorical retaliation after a naval attack that killed a fisherman) reconfigures an alliance that until now was key for Washington: the same one that provided the 80% of intelligence in the area. In other words, the clash erodes the regional pillar precisely when the United States approaches the use of force threshold in Venezuela, expanding the diplomatic front and reducing its margins for sustained maneuver. The political window. While, Donald Trump’s administration acts against the clock: this posture sustained under a climate of war does not seem to be able to be maintained indefinitely and any accident can precipitate an unplanned escalation. Plus: Trump does not seem to focus the operation on normative criteria (elections or institutional guarantees) but rather to a result that he can declare as “victory,” which makes the margins of American rhetoric more flexible, but hardens the incentive for a spectacular blow. Military analysts warn that “over braking” could behead without transition and opening a vacuum, while the opposition replies that Venezuelan social cohesion reduces that risk. Thus, the gap between both hypotheses is precisely where the greatest American pressure operates today. Strategic test. In summary, the combination of visible military troopscredible threat of precision hits and a diplomacy that does not stop tightening the rope, define that kind of ultimatum phase but without a formal ultimatum. From that perspective, the outcome aims to depend less on the balance of fire than on the breaking point within the Chavista leadership and whether Washington decides to stop after a possible departure of Maduro, or explicitly pursues the “end of” as a regime. And while that ambiguity persists, the pressure aims to continue… while the Caribbean wonders for how long.

Two years ago, an asteroid exploded over France with unusual violence. What saved the French was their size

by

February 13, 2023. It was 4:59 in the morning when a violent explosion illuminated the skies of Normandynorth of France. It was not a ray, nor a missile. It was the end of a travel of millions of kilometers for a small asteroid called 2023 Cx1. Seven hours of notice. The 650 -kilogram rock had just a meter in diameter, so it had been detected only seven hours before impact. But the most disturbing thing was not his surprise arrival, but his behavior when entering the earth’s atmosphere. An exhaustive analysis published two and a half years later in Nature Astronomy He has revealed that, if the asteroid had been larger, the consequences of his extraordinary explosion could have been devastating. A high -risk meteor. Most meteorites are fragmenting as they descend through the atmosphere, but 2023 CX1 endured intact until it reached a distance to the ground of only 28 kilometers. At that point, the pressure made it explode like a pump. After traveling through space for about 30 million years, the asteroid released 98% of all its kinetic energy in a second fraction. And in a very concentrated region of the atmosphere, when it reached a dynamic pressure of 4 megapascal. It does not compare with Cheliábinsk. The 2023 CX1 behavior was radically different from that of the car whose explosion of 500 kilotons He broke windows and caused hundreds of injured in Russia in 2013. The one in France generated a spherical shock wave instead of cylindrical, concentrating much more energy and greatly increasing the area of ​​soil affected by overpressure. According to researchers, this type of abrupt fragmentation could cause much more damage than the progressive fragmentations of similar size bodies. The French were lucky that it was so small. More firewood for planetary defense. The analysis was based on an unprecedented number of observations after mobilizing the scientific and citizen community in those seven hours of margin. The prediction of the fall by ESA and NASA had a margin of error of less than 20 meters between the planned and observed trajectory, which in turn facilitated the recovery of more than one hundred fragments of the meteorite in the commune of Saint-Pierre-Le Viger. According to the CSICwhich participated in the investigation, this event confirms the existence of a new population of asteroids, type L chondrites, capable of these violent explosions. “These asteroids must be taken into account in the Planetary Defense Strategiessince they represent a higher risk for populated areas, “says Auriane Egal, first author of the study. With what we know today, perhaps the authorities activate evacuation plans the next time an asteroid of this type threatens us. Provided that detection systems do not fail, and detect the threat in time.

50 years ago, a man won the ‘US Dakar’ with an unusual co -pilot: his dog

by

Dogs have been evolving thousands of years to become our best friends and They have a special memory When it comes to remembering our pampering. Other memories have a very short life in their head, but the safest thing is that Kookie, a mestizo dog, will remember throughout his life the adventures he had with John McCown, his owner. Because they did not give normal walks through the park: they toured the motorcycle desert competing in official tests. And Kookie was not the package: it was the co -pilot. The strange couple. Imagine The scenetoday impossible due to so straight regulations, the era of telemetrías, the absolute control of each extra gram in a competition vehicle and the most absolute technification: a dog uploaded on the deposit of a motorcycle, which competed in official tests and was moving based on the land they were going through. In the 60s, the carnicero by profession John McCown liked to walk with his bike. He did it accompanied by Kookie, his dog, who placed a back basket. At one point, John was going to go one step further: he bought an off -road motorcycle and began to get into his head that could compete in Cross competitions. He did so, and did not leave Kookie behind. My dog ​​knows how to wear the motorcycle. Instead of a basket, John improvised a “seat” with a blanket on the gas tank of his Husky 400 and OSSA 175 SDRand that is where Kookie felt like fish in the water. I imagine that the dog would be waiting for good doses of bones at the end of the day and that was the motivation, but the truth is that I was not there to make bulk: John and Kookie trusted each other to wear the motorcycle. During about 300 tests, the couple ate hundreds of potholes, swallowed dust and crossed puddles while both adapted their position on the vehicle to tame it in the best possible way. In This article From the American Motorcyclist magazine, McCown’s wife, McCown Describe That Kookie bowed to the curves, leaned on the deposit in the rugged field and stood up when potholes came. A bomb. Both executed a choreography on the motorcycle, and although at first they did not do it as an advertising maneuver, it is evident that it caught the attention of many. They appeared in the documentary movie ‘On Any Sunday‘, Kookie starred in children’s books such as’ Kookie the Motorcycle Racing Dog’ and ‘Kookie Rides Again’ and even brands like Ossa, Can-Am and Kawasaki the They sponsored. Kookie Junior. When Kookie got on the motorcycle, she was 10 years old. Hundreds of races later, and with 13, after a check, McCown preferred that his compi would limit to some shorter and less demanding races. Until 14, when John decided that Kookie should hang the helmet and live on the couch. He died at age 16, but as John remembers in the 1981 article, before leaving he left a litter. One of them was baptized as Kookie Junior, and for 10 years, he ran with John as Kookie had done before. They got some off-road championship (such as the 175cc class championship) and, although some wondered if it was not crazy, it was a friendship that benefited both of them for fun and for the company in the long and hard careers for the western American deserts. To the hall of fame. Such was the legend of McCown and Kookie (s) that were included In the Hot Shoe Hall of Fame, an organization and museum dedicated to preserving the history of motorcycle races in ‘Flat Track’ and ‘Speedway’, recognizing both the pilots and the mechanics, personalities and influential journalists in that world. “Kookie learned to read the terrain, leaning back in the rugged and standing at the most smooth. John could always know what came ahead because of the way Kookie moved.” – Description of the “plaque” of the Hot Shoe Hall of Fame. Unfortunately, that recognition is something that John did not live. McCown He died In 2011 due to complications after cardiac operation. On the other side, surely Kookie and KJ were waiting for him, with the engine on and ready for one more adventure.

It is so unusual that the government has created a commission for possible crises

by

An exceptional cosmic carambola looms over Spain. Until Three solar eclipses will cross the Spanish territory In less than three years, starting with the most spectacular of all: the total solar eclipse of August 2026, which will obscure a third of the country. It is so unusual that the government has mobilized thirteen ministries to create a contingency commission. The eclipses trio. On August 12, 2026, a total solar eclipse will draw a 200 km line From the northwest to southwest Spainentering through Asturias and dating Castellón to cross the Balearic Islands just at sunset. The totality phase will last about two minutes on the central line. It will be the first eclipse of this type in the Peninsula since 1905. On August 2, 2027, the shadow of a total solar eclipse will enter through the Bay of Cádiz, crossing the strait and leaving Almeria. Ceuta, Tarifa, Cádiz Capital and part of Malaga will enjoy almost five minutes of dark in mid -morning. It will also be one of the longest eclipses of the century. On January 26, 2028, Spain will also live an annular solar eclipse. The “Fire Ring” will travel the country from Southwest to Northeast shortly before sunset. From Huelva, Sevilla and Córdoba to Valencia, Aragon and part of the Balearic Islands. The annularity will be around seven minutes and will be seen with the sun. Outside the strip it will be observed as partial. The government mobilizes. “The eclipses trio will be an unprecedented astronomical phenomenon, which can virtually only be seen in Spain between 2026 and 2028”, Minister Diana Morant affirmed. “In the Government we are already working to face the logistics and security challenges that this historical event will mean.” The magnitude of the event has led the Council of Ministers to Approve the creation of a special commission To organize and coordinate all actions. It will be formed by representatives of thirteen ministries. From science and transport to interior, defense or ecological transition, through the National Astronomical Observatory and the great astrophysical institutes of the country. The Secretary of State for Science, Juan Cruz Cigudosa, will preside over the Commission, which hopes to convene the first meeting at the end of August. The challenges of eclipses trio The chaotic experiences lived in the United States during the eclipses of 2017 and 2024 already put on the table the main open fronts: Congestions and accidents. The government expects an influx of hundreds of thousands or millions of people. The strip of totality of the eclipse of 2026 will only touch land in Greenland, Iceland and a much more populated and sunny country: Spain. The foreseeable result is the collapse of highways and secondary roads, with kilometer traffic jams that could block the passage to emergency vehicles. Oregon is the mirror in which nobody wants to look: he had Your overflowing access roads for three days in 2017. Infrastructure overload in emptied Spain. Many of the best observation points They are found in rural or coastal areas With limited resources. The sudden arrival of hundreds of thousands of people could cause the exhaustion of basic services such as drinking water, food, fuel or bathrooms. Mobile coverage could also saturate, leaving those same incommunicado people. The government plans to enable “minimum services” at the observation points. Extreme fire risk. Total solar eclipses will coincide with summer: drought, high temperatures and thousands of cars parked in fields and gutters. It is the perfect recipe for a disaster. The risk of forest fire will shoot. The precedent is, again, A fire in Oregon in 2017 which forced to evacuate hundreds of households in the middle of the totality zone a few days before the eclipse. Pest of false eclipses glasses. Looking directly at a solar eclipse without adequate protection can cause retinopathy, Irreversible damage in the retina. To see an eclipse it is crucial to wear approved glasses with ISO 12312-2. The problem is that with each eclipse the falsifications between vendors that make their August proliferate. In 2017, Amazon had to withdraw thousands of units and reimburse money from buyers. The first big photovoltaic blackout. A challenge of the 21st century. Spain has 25% of installed solar power. A total eclipse will cause an abrupt fall of the photovoltaic generation of up to 20 GW in less than an hour, followed by an equally fast climb when the sun reappears. Managing this undercut and the peak that follows will be a major challenge for Red Electrica, which will have to coordinate energy reserves to guarantee the stability of the system, as European operators did during the eclipse of 2015. Tourist saturation and its effects. Astronomical tourism is a blessing, but it can also be a problem. Airbnb talks about An 830% increase In rural accommodation searches by August 2026. prices fired in hotels and rentals, temporary gentrification and the possible displacement of the usual tourist are expected. In addition, there may be an impact on labor productivity: workers taking the day to see the phenomenon. The United States estimated losses of almost 700 million dollars during working hours. The unpredictable meteorology. The whole plan can jump through the air if clouds appear. A forecast of covered skies would cause massive displacement at the last minute to places with a better prognosis, multiplying chaos on roads. Astrophysico Alejandro Sánchez summed it up in The country: “Due to the unpredictable of the weather conditions, it is as if we did not know where the World Cup final will be celebrated until a few hours before.” The public cost and the environmental footprint. Deploying a device from this magnitude has a cost: traffic reinforcements, health, mass cleaning … to which the environmental footprint must be added: abandoned garbage, erosion of natural places and carbon emissions of millions of displacements. Problems that the contingency commission will have to value. A historical opportunity Despite the challenges, the Iberian trio of eclipses It will be a golden opportunity for science, education and … Read more

Before the lack of steel, the ships of World War II began to be built with an unusual material: concrete

by

Close your eyes and think about the main material of a ship. Quite possibly Wood is the first Let it come to mind, and it is normal: we have millennia sailing in wooden ships, and we continue to do so. But it is also logical that the steel that dominated the XX and XX shipsand the Current marine monstersit is around ideas. And most likely you have not thought of another material: the concrete. But yes, for 150 years we were creating concrete ships, and far from crazy, it was the most logical idea. And even used in the first and Second World War. A Frenchman. A good day from the mid -nineteenth century, a French man named Joseph-Louis Lambot It occurred to him to build a boat. Not anyone: one of reinforced concrete. There was a problem: in 1848, they had no idea what reinforced concrete was. This material, basically, is the mixture between concrete and steel. Both combine to create something with much greater structural resistance and has been since their invention the basis of the most imposing, dams and almost any construction of the last century. Well, it was Joseph-Louis that came up with the two materials. At least, I know attribute The invention of reinforced concrete to this man. As always, there is controversy with the dates, with whom he patented the reinforced concrete, who built the first slab, etc. But well: Lambot wanted to prove his invention and built a small boat less than four meters with the aim of exhibiting it in the Universal Exhibition of Paris of 1855. Enough advantages. Basically, the interior was wire mesh covered by cement and Lambot’s idea was to completely replace the wood. The invention liked it, but it really did not attract the attention of ship manufacturers. Some barges were created for European channels, but little else. Everything changed when the Italian engineer Carlo Gabellini built the Liguria in 1896. It is the one we consider as the first reinforced concrete ship designed to navigate on the high seas. And, really, it made sense to create reinforced concrete ships. It is a material that has great corrosion resistance, so the marine environment does not damage the helmet, reducing maintenance (that also has it) and extending its useful life. It offered good thermal insulation, so perishable resources could be transported in better conditions and there were no fire problems. The Namsenfjord In the absence of bread … A few years later, the construction of these concrete ships expanded and other countries began to build, especially freighters. But of course, we are in 1914 and that means something happened: the World War I. And beyond the advantages of concrete against other materials, the world was forced to create concrete ships for a very simple reason: There was no steel. The militarization and industrialization of the belligerent forces caused a situation of Steel shortage. The ships were important, since the naval supremacy It has always been a determining factor in a conflict, but with the steel necessary for a destroyer you could create many other things. And the problem is that they had to continue building ships because there were resources to move worldwide. World War I. The revolution came with the Namsenfjorda Norwegian ship that, in 1917, showed that self -propelled concrete ships could be made. It was 26 meters in length and weighed a whopping 400 tons and most importantly: the United States saw that there was a potential in these ships beyond serving as charges propelled by an auxiliary ship. Thus, they created the Emergency Fleet Corporation program with the aim of producing 24 concrete ships. It was a failure: those who completed themselves, did it after the war, so it had to be allocated in other things. One was the SS FAithwhich was going to serve in the war, but in the end it remained to be used in transport work in the United States. It was thrown in 1919, it was in service until in 1921 it was sold to Cuba and had a length of 97.54 meters. A year after Faith, the SS Selmaa huge reinforced concrete mole of 129.54 meters in length that was launched just the day when Germany signed the Treaty of Versaillesending the First World War. It ended up using as a oil tanker in the Gulf of Mexico. With candles and a secondary support motor Demolish disadvantages. With the finished war, interest in the construction of concrete ships deflated. It still had advantages, because building them was much cheaper than making them in steel or iron, but if we mentioned a series of advantages, it is important to know the disadvantages (which exceed them, and by far). To match the resistance of a steel helmet, the concrete is thicker, which has several limitations. On the one hand, it weighs more, so it also has a major draft, the displacement of the ship is slower and more fuel is needed. That is thicker implies that there is less interior space for load, since the useful volume is reduced. That weight makes engines must be more powerful and that fuel tanks are also greater, so the investment in this part is greater. The dike to build it must also be monstrous because you cannot weld parts, such as steel, and then there is resistance to impacts. Second World War. The metal breaks, yes, but it has a greater elasticity than the concrete. This material, however, is much more fragile to impacts. A collision causes a crack in the helmet, and this on a ship that weighs so much is a conviction. That is why, after the great war, the concrete ship project was abandoned, leaving its construction practically limited to the loading barges, but then World War II arrived, and the steel needs of the previous one were repeated. However, the US program was not as ambitious as the one that began 20 years before and yes, concrete ships were … Read more

Elon Musk has said that Mars will be part of the United States. It is an unusual affront to the outdoor space treaty

by

See Elon Musk on stage in a political event is already a guarantee that In the morning the bread will upload. But this time his words have resonated beyond the Earth’s atmosphere. The echo has felt up to Mars. The phrase. During a political rally in Wisconsin, with a gigantic American flag projected behind him, and dressed in his Spacex blue jacket, Elon Musk pronounced The following phrase: “I will die in the United States. I’m not going anywhere. I could go to Mars, but it will be part of the United States.” The affront. He Treaty about outer space From 1967, signed today by 115 countries, it establishes that “the ultra -resort space, including the moon and other celestial bodies, is not subject to national appropriations by claim of sovereignty, through use or occupation, or by any other means.” Musk’s statement, individually, does not directly violate the agreement, which is only binding for governments. But his words are an unusual affront if they are interpreted as a suggestion that the United States will claim Mars as his, violating international law. The contradiction. Interestingly, Spacex, Elon Musk’s aerospace company, keeps in the Starlink service terms A legal notice about Mars that contradicts the treaty and in turn the recent statements of its founder: “For the services provided on Mars, or in transit to Mars through Starship or other spacecraft, the parties recognize that Mars is a free planet and that no land government has authority or sovereignty on Martian activities. Consequently, disputes will be resolved by principles of self -government, established in good faith, at the time of the Martian resolution” What is the plan. Since the foundation of Spacex in 2002, Musk’s long -term vision includes the Colonization of Mars. Its objective is to establish a self -sufficient settlement on the red planet that would guarantee the survival of humanity as a multiplaneary species if something happened on earth. Spacex is developing the Gigantic Rocket Starship To give logistical support to this titanic project, and plan launch the first unmanned missions At the end of next year. But at the time of truth, only governments and hundreds of thousands of volunteers willing not to return They would have the ability to carry out a permanently inhabited colony on Mars. Political pressure. NASA marked as a priority objective the return to the moon, but Musk, which Consider the moon “a distraction”he is pressing the agency with its political power and its enormous resources to accelerate the missions with astronauts to the red planet. You have already got Donald Trump Declare Mars the “manifest destiny” from the United States, and things could get even more on their part if Jared Isaacman, Spacex’s commercial partner, assumes NASA administration after being nominated by the president. Against the law. Of course, one thing would be to plant the American flag on Mars, something that also China intends to do with yours in 2040and another very different would be to claim the independence of a Martian colony. Any property claim on Mars, does NASA or Spacex, would be considered an American claim, due to its continuous jurisdiction, and would be prohibited. If Musk’s declaration is interpreted as a territorial claim, It would be incompatible with the principles of the international treaty. On the other hand, it is true that Musk has no problem changing his opinion. Until recently, he argued that Martian settlers would directly legislate the planet with a political self -government system for direct democracy. The laws would be voted by the people, without political intermediaries, the businessman proposed.

A jeweler has found a rolex that gives the date in an unusual language for luxury watches: the Catalan

by

The sale of high -end watches has become a More investment formthanks to the high value that certain pieces acquire. In recent months, the second -hand watch market has suffered A drastic fall After a pricing bubble derived from the shortage of supply against high demand. That has made this a good time to find Pieces at a good price. The tiktok @jewelrybarcon account, shared The discovery of a curious piece that bought a few days ago: a rolex day-date, also known as Rolex President with very special gold finish. The initial emotion of buying a rolex like that, became surprise to discover that the days of the week that are shown in the sphere were in Catalan, instead of having them in Spanish or English as usual in the Swiss brand watches. Something that in principle could light alarms in front of falsifications. At first, the young man thought this could be a problem if he decided to sell it in the future since the clock would have less demand to be in a different language. However, after an initial investigation he discovered that the story that locked that clock made him a very limited and exclusive piece. The mystery of the Catalan rolex The user explains in his video that it was very strange that a Swiss company like Rolex manufactured a clock in Catalan. The explanation that found that curious finish was that, in reality, a group of Andorra businessmen had asked Rolex to make a special roll with texts in Catalan. This limited edition occurred until 2007, which, according to the young Tiktoker, makes it a very sinned rarity. What initially seemed a possible inconvenience became a distinctive feature that apparently increased its value significantly. Now, your rolex is not only a luxury accessory, but also a collection piece With an interesting story. So far what social networks say. Rolex Day-Date is the most international rolex The reality is that Rolex is an international brand and, within its catalog, the Rolex Day Date, better known as Rolex President, is The most international of all. So much so that it not only has daily dials translated into Spanish or Catalan, but can also be found in Vasco, in Farsi, in Chinese or in Ethiopian. As he points out in his own Rolex’s official pageDay-Date speaks the language of who takes it and, since 1973, it is Available in 26 languages including alphabets in Latin, Arabic, Cyrillic, Hebrew, Japanese, Chinese ideograms and even the ge’ez alfasilabarium used in the horn of Africa. The linguistic peculiarity of Day-Date makes, in reality, the language is not an exceptionality itself because of the fact that a group of Andorran businessmen asked for their watches in the official language of their country. However, it is a distinctive feature, because it is a rolex of a certain year, with a certain finish and with the addition of being in Catalan that is not a highly demanded option. In no case would it be a rare and exclusive piece since anyone can choose the language of the dial with the days of the week when configuring this watch. Its second -hand price can range between 20,000 euros and 45,000 euros according to their status and characteristics.

A Pakistani astronaut at the Chinese space station is not only unusual. It is China occupying US power vacuum

by

In the coming years, the Chinese Space Station Tiangong You will receive your first crew of another nation, Pakistan. Although it will be a short -term mission, it represents a cycle change: China opening to other countries, while the United States closes. The agreement. China and Pakistan They signed a cooperation agreement on Friday To train Pakistani astronauts and perform the first international missions to the Chinese Space Station Tiangong. China and Pakistan will dedicate a year from May to select Pakistani astronauts, who will be trained in China before joining their counterparts in the neighboring country in the Orbital Laboratory for short -term missions. Chinese-Pakistan ties. Pakistan was one of the first countries to recognize the People’s Republic of China in 1950. The two nations have continued to strengthen ties since then, both economically as in the military and technological: according to the CIA, China even helped develop Pakistan’s nuclear program in the 80s. In recent years, Pakistan has sought to improve his spatial capabilities by resorting to the help of his neighbors. In May, it was one of the countries that placed experiments aboard the Chang’e-6 lunar probe, which ended up turning China into The first country to recover successfully Soil samples of the hidden face of the moon. Which symbolizes tiangong. China decided to develop its own space station after the United States prohibited Any direct collaboration between NASA and the Chinese Space Agency (CNSA), preventing its participation in the International Space Station. After trying two prototypes (Tiangong-1 between 2011 and 2018 and Tiangong-2 between 2016 and 2019), China launched the first module of its permanent space station in 2021. The Tiangong Space Station has three modules and is uninterruptedly inhabited Since 2022, with astronaut rotation missions, first, every three months, and then, every six. The twilight of the ISS. With 16 pressurized modules (the oldest, 26 years old), the International Space Station has long been the maximum exponent of cooperation between countries. But Structural fatigue begins to be a problem and maintenance investments have been increasing. The official plan (Elon Musk has his own) is to keep the ISS operational until 2030 and then tow it to a safe place where to let it disintegrate by entering the atmosphere. Roscosmos, the Russian space agency, wants to have its own space station, and NASA trusts that the ISS is replaced by a commercial stations plethora. The future of the low orbit. There are few companies that are developing commercial space stations to offer space tourism services, experiments in microgravity and, ultimately, cover the hole that the ISS will leave from 2030: Axiom Space, Blue Origin, Voyager Space and Airbus… But neither does it lack ambition to China in the extensions planned for its space station, Tiangong, which in the coming years will double the number of modules to six And it will begin to accommodate, as we have seen, astronauts from other countries. Another next milestone will be the launch Xuntian Space Telescopescheduled for 2026. It will share the same orbit as the station (400 km altitude) and may be coupled to it for maintenance and improvement tasks. China occupies power vacuum. When NASA definitely abandons the low terrestrial orbit (or delegate it to its commercial partners), China will be there to occupy the void, opening to other countries to accommodate its astronauts, taking advantage of a abandonment of functions in international cooperation. It will not be the first time that China occupies a space that the United States leaves free. It has occurred on the Moon, ignored by NASA for a long time from the Apollo missions, occasion that the Chinese space agency took the opportunity to achieve symbolic milestones such as alunizar on the hidden satellite face and bring the first soil samples. Cycle change. With NASA receiving instructions to conquer Mars after Elon Musk convinced Donald Trump that the moon is a distraction, the NASA Artemis missions They are questioned. Now China has an opportunity. Not only to establish the “De facto International Space Station” in the low terrestrial orbit, but also a series of milestones that NASA had marked in its calendar of symbolic victories. The First woman who steps on the moon It could be China, if Artemis ends up falling apart. And then the first lunar orbital station? And then the First manned lunar base? If there is a cycle change, China will take advantage of it.

Microsoft’s general director’s opinion about AI is unusual. And suspect how much the global economy will grow thanks to it

by

Satya Nadella, the general director of Microsoft, has intervened in the Dwarkesh Patel podcast. During Your interesting conversation of something more than an hour and a quarter duration This executive has touched many sticks of hot actuality for its relevance in the world of technology, but in this article we propose to investigate two of them: the artificial intelligence (AI) and the Quantum computers. And Microsoft objectively has much to say in these two disciplines. With regard to quantum computers, Redmond’s have surprised us with the presentation of a new architecture expressly conceived for these machines. Majorana 1 It is the first quantum processor devised to Use the exotic particle Theoretically proposed by the Italian physicist Ettore Majorana almost 90 years ago. Whatever the really important thing is that Nadella argues that it is possible that thanks to this Microsoft technology you can put a quantum computer equipped with millions of cubits and capable of solving a very wide range of problems in just four years. Satya Nadella believes that AI is not being evaluated correctly We are all witnessing the thrilling rhythm of development that is experiencing AI. In fact, during the last two years this technology is monopolizing the attention of the great powersresearch institutions, companies, and, of course, also of users. And nothing seems to indicate that this trend will change. Not at least in the short or medium term. Satya Nadella’s speech defends the importance of AI, but, surprisingly, this executive argues that her evolution is not being evaluated in the proper way. “Thanks to AI it is possible to increase productivity (…) The real reference point is that the global economy grows 10%” “For me it makes no sense to self -proclaim (human beings) that we have reached some milestone in the field of General Artificial Intelligence (AGI for its English denomination). It is only a manipulation of the performance tests that, in my opinion, is meaningless (…) the winners will actually be the industries that Be able to use this technologywhich, by the way, is abundant. Thanks to it it is possible to increase productivity, so the economy grows at a faster rate. The true reference point is that the global economy grows 10%”, SATYA NADELLA has pointed out During his conversation with Dwarkesh Patel. It is worth not overlooking two important points of this statement from the head of Microsoft. On the one hand it is evident that it is moderating the enthusiasm that They have triggered Openai and other companies in the always controversial land of the AGI. And, what if possible is more relevant, proposes a bar to measure the development of the different AF -is being used, and that requires evaluating its direct impact on economic growth. But there is something else. Something very important. And it is that Nadella has suggested, as we have just seen, that AI could trigger a global economic growth of 10%. We will see if the time finally is right, but a priori does not sound at all far -fetched.
