The anger between Musk and Trump has made Tesla lose 100,000 million dollars. Is the least of his problems

by

Elon Musk and Donald Trump have staged for hours a breakdown of a bloody divorce. With accusations exchanged in which it has threatened to withdraw aid to electric cars, the Disassembly from the International Space Station And it has come to the fore to Epstein’s namethe afternoon has been moved in the United States. The clash has mobilized the entire Maga Movement In favor of each other (including the request of the Elon Musk deportation). And, in the middle of all, Tesla. 14%. Without a doubt, the afternoon figure in the United States. That is what The actions of Tesla came to fall Although, at the end of the day, there was a small rebound that left the action losing more than 11 % at the end of the day. Thus, the price of the action started the day exceeding $ 322 and closed it by $ 284.70. If the final rebound had not occurred, we were talking about the shareholder would have left another 10 dollars per share. However, it is estimated that Tesla has left some 100,000 million dollars Yesterday. On a personal level, Elon Musk has seen 34,000 million dollars volatilize with his discussion yesterday. Although we focus here on Tesla, we must not lose sight of the US government contracts with Starlink or Space X. The youngest of the problems. In total, it is estimated that Tesla has lost $ 100,000 million in the last fight between Trump and Musk. The dialectical crossing has caused a socavon in the graph of the actions but that is not the greatest of the problems. Now, with Trump as an enemy of Musk, Tesla has to row in a complicated scenario. The Robotaxi. It is the first indicated. Elon Musk announced that The first deployment of the robotaxi Tesla would take place in the city of Austin (Texas) whose mayor is from the Democratic Party But there are more derivatives that are intimately linked to the expansion of the service. However, The Governor of Texas is a republican And, in fact, the State is one of the bastions of the party. To this is added that NHTSSA is a state entity in charge of appraining the novelties that want to apply to circulate on the road. With their decisions, for example, it forces operators to have flyers and pedals In their cars, something that I wanted to eliminate Elon Musk in his robotaxis. The NHTSSA. The National Highway Traffic Security Administration (NHTSA) is also responsible for carrying out the accident investigations that occur when driving aid systems are active and has actively pursued the highway of Tesla. Its financing depends on the United States Congress and depends on the Department of Transportation that is directed from the Government. In addition to the previous investigations, it is the one who is approved so that a vehicle can work with a higher level of autonomy. For example, it is the one who rewarded Mercedes with the possibility of circular without the driver paying attention to what you have ahead. Yes indeed, In very specific circumstances. The aid. The withdrawal of the aid to the purchase of electric cars was something that, initially, did not seem to worry Elon Musk. Right now, the company’s leadership is so evident in the United States that they are the competitors of Tesla, who cannot offer the same autonomy-price relationship, Those who have to lose. However, it is clear that the withdrawal of aid can damage the sales of the company and Tesla is not in a position to leave sales right now. In Europe, Every month passing is a bleeding and In China its sales have also decreased To the point that Byd is already the brand that VWe are more purely electric cars In the Asian country. Regulatory credits. Another of the income roads that Tesla has been exploiting in recent years is the EMISSION CREDIT SALE. Donald Trump also showed his intention to prevent this type of practices that allow Tesla to draw income that since 2012 They have added 11,000 million dollars. When accountability before the institutions, companies have to meet emission objectives. If they exceed the maximum allowed figure, they can Buy emission bonds to companies that have not reached said limit. Thus, they lower their average emissions and avoid a strong fine. The beneficiary company receives the money from a competitor but although the number of emissions increases, of course, below the limit that marks the economic punishment. Goodbye to the Stock Exchange. Although it is not the biggest problem, the last six months have been a roller coaster of emotions for Tesla’s shareholders. At the end of 2024, the company closed the records in record, touching the $ 480 per share in mid -December last year. Since then, the controversial messages of Elon Musk, His Nazi greeting during the day Donald Trump took command of the United States or Your support for the AFD ultra -right party in Germany caused a sudden fallen that made us clear to what extent the image of Musk viciaba the stock market of the actions of Tesla. Little by little, the rumors of his departure from the United States government were already consolidating from mid -May, the shares consolidated the rise that had already begun in April. On May 7 the shares were worth $ 276. The confirmation that Musk focused on Tesla He lifted its price up to $ 363. In a few hours the entire climb has eaten. And what is expected. In addition to the obstacles that the United States government can put to the expansion of robotaxis, the elimination of regulatory aid and credits, it remains to be seen how the shareholders will receive divorce between Musk and Trump. Tesla is not going through her best moment. Its sales have collapsed in Europe And in China the rivals have been eating ground for a long time. It remains to be seen if the arrival of the Tesla Model … Read more

In case we had not had enough problems in the electricity network, a “severe” solar storm has come to complicate it

by

The closeness of the Pico de Activity of the last solar cycle implies stirred times in the field of “spatial meteorology.” And we have seen one of the most important during these days, a “severe” geomagnetic storm caused by this activity. Geomagnetic storm. The last two days have been days of “intense” solar activity. The geomagnetic storm has reached a Kp = 8 index, which implies that it has been a “severe” storm, from G4 category (On a scale that goes to G5). The value of the index has descended since then: the last data offered by the NOAA spatial meteorological prediction (National Oceanic and Atmospheric Administration) indicates that the value Average Index KP In the last three hours it has been kp = 6. Despite this, spatial time is still scrambled and According to forecasts He will continue to be until tomorrow. An ejection of coronal mass. According to He explained yesterday The Spanish Space Agency through a statement, the origin of this activity is in a high -speed coronal mass ejection (CME), associated solar fulguration of class M8.2 and with origin in the Ar4100 active region. KP 8. What does that mean of kp = 8? The K Geomagnetic Index measures disruptions in the land magnetic field and is used to characterize the magnitude of geomagnetic storms, especially through the planetary index K or KP Index. The latter uses a series of magnetometers distributed in stations located in various parts of the planet. The indices above kp = 5 are associated with a specific degree in the geomagnetic storm scale Employed by the NOAA SWPC, being G1 (minor) the smallest category on the scale and G5 (extreme) the category that denotes the strongest storms, those of index Kp = 9. A G4 storm. The storm recorded on Sunday, with a Kp = 4 index led the center to alert a “severe” or G4 geomagnetic storm. In your noticethe SWPC pointed out that, in addition to intense northern lights and lower latitudes than usual, possible impacts on infrastructure and networks, including problems with satellites and loss of precision in the GPS. The Category events They usually imply possible problems with voltage control that can also cause “mitigable” problems in electrical networks. At space vehicles, the SWPC indicates that these storms are associated with possible monitoring problems that require future corrections. Finally, other possible impacts are on the spread of HF radio signals and low frequency radio navigation. An active solar cycle. The situation has stabilized With ups and downs And, although the last one average three -hour data from the KP index is 6, the SWPC has already reduced the intensity of the storm to G1, or minor storm. The last months have been revolts as far as spatial meteorology is concerned. In October 2024, A similar situation He brought spectacular dawn. According to estimates From the experts we are already after the peak of activity of solar cycle 25, but we have not yet moved away much so the solar activity remains intense. Perhaps this is not the last storm of these characteristics that we see in the coming months. In Xataka | We have detected the exact date on which the most brutal solar storm occurred in history.

The problems of nuclear fusion are falling behind each other. Optimism cornering denialism

by

The challenges raised by the nuclear fusion intimidate. And it is to replicate on our planet and small scale the same reactions that take place in The interior of the stars It is a titanic challenge. Even so, The human being has already traveled A very important part of this path. There is a belief that defends that in the field of nuclear fusion we have barely advanced since World War II, but, as we will see in this article, it is not so. There is much to do, but we have advanced a lot. In order for electric power plants equipped with fusion reactors to be viable, it is necessary to solve problems that are still dealing with engineers. And it is that the challenges posed by nuclear fusion right now reside in the field of engineering, and not in that of basic science. In fact, Spain will actively participate In the search for the solution to one of these problems thanks to IFMIF-DONES (International Fusion materials irradicion facility demo-eraned neutron source), The installation that is under construction (Granada). Its purpose in broad strokes will be to develop a source capable of producing high energy neutrons with the intensity and volume of irradiation necessary to test candidate materials to be used in future fusion energy plants. This is one of the pending challenges, but many others have already been left behind thanks to the great work that scientists have carried out in experimental reactors, such as the already “retiree” JET (Joint European Torus), which is housed in Oxford (England). Let’s trust the reactor JT-60SA of Naka (Japan), and, above all, ITER (International Thermonuclear Experctor reactor), are up to expectations. Eurofusion and the University of Texas have made two new relevant contributions We can imagine in an intuitive way a nuclear fusion reactor as a pressure cooker in which two essential ingredients are cooked: deuterium and trity. To ensure that the nuclei of these two hydrogen isotopes merge and release the neutron that will ultimately allow us to obtain a large amount of energy it is necessary to confine them in an extremely hot plasma. In fact, so that this process takes place, a temperature of at least 150 million degrees Celsius must reach. Scientists know how to do it, so submitting the deuterium and tritium nuclei at the pressure and temperature to get me to merge is no longer a problem. What still represents a challenge is to achieve Keep turbulence under control. Otherwise, the plasma will be destabilized, its density in the critical regions will be affected and the support of the fusion reaction over time will not be possible. The mechanisms that govern this process are very complex, but little by little physicists and engineers who work in fusion energy are getting them better. The QCE (‘Quasi-Continuous exhaust’) regime is characterized by eliminating periodic instabilities that occur on the edge of plasma In broad strokes what they intend is to minimize turbulence so that the loss of plasma energy is minimal. Two of the tools that these technicians have are the artificial intelligence (AI), which is playing a very important role in understanding the mechanisms that govern plasma behavior, and Rebco superconductor magnets. In fact, The sparc fusion reactor that is building the American company Commonwealth Fusion Systems (CFS) uses them. Precisely Eurofusionthe European organization that is responsible for promoting and supporting the scientific research necessary to bring to fruition The European Nuclear Fusion Planhas recently made an important contribution in this field. And it has shown that in the reactors Tokamaklike Jet or Iter, it is possible to use an operation mode known as Qce (Quasi-counts exhaust) that is characterized by eliminating periodic instabilities that occur at the edge of plasma, and, at the same time, it supports high density in this region of gas and preserves a very high level of energy. Gradually the confinement and stabilization of plasma are no longer a problem. The other recent contribution in which I propose that we investigate it briefly has been carried out by a team of researchers from the University of Texas and the National Laboratory of Los Alamos, both in the US. In the article they have published in Physical Review Letters These scientists propose the creation of a magnetic confinement system without leaks ten times faster, according to their calculations, than the standard method without sacrificing a precision apex. This innovation is important because it helps to resolve the containment of high energy particles within the reactor, and, therefore, to avoid the loss of temperature and density in the critical regions of plasma. Yes, as I mentioned a few lines above, much remains to be done in the field of nuclear fusion, but definitely every day we are one step closer to commercial fusion energy.

After the mass blackout of Spain he feared looting and security problems. Reality was very different

by

Nor pillage. Nor Latrocinio. No chaos unleashed in the streets. Although most of the country stayed yesterday to two candles (literally) and Thousands of Spaniards They went to sleep yet without electricity in their homes and businesses, on April 28, 2025 will not go down in history because it is a day of chaos. Not everything was An oil raftof course, but this morning the Interior Ministry He underlined that the night has been “quiet”, “without remarkable security incidents.” Nothing that the country has not already lived during the pandemic, when Spain already demonstrated its obedience during the alarm states to stop the COVID-19. That almost a country is based black (in energy terms), as happened on Monday at 12.33 h in Spain, it obviously has multiple derivatives. It affects the industry. It affects trade. It affects mobility and education. And affects security. Yesterday the government declared The national emergency in eight communities and one of the issues that was in the public debate during the first hours was precisely The media deployment To guarantee security. “Security problems” “Madrid has 9,000 streets, 3.5 million inhabitants … If a city is these dimensions, we are all aware, we are all aware that they can give Security problems at very diverse and different points “, warned In the afternoon the mayor of Madrid, José Luis Martínez-Almeida. Without electricity, many businesses were left without a dataphone, but also without surveillance or automatic systems that allow them to close their premises. The fear of looting and robberies during the blackout even led some merchants to monitor their stores. In Ayamonte, Huelva, there were who The night passed In their businesses unable to lower the blinds and in Granada the newspaper Ideal speaks of entrepreneurs in a similar situation that resisted to leave their premises. “People take advantage of to steal and we have no system here that allows us to ensure the store,” admitted a ABC The clerk of a store in the center of Madrid while waiting for the supply to be restored. His suspicion was understandable. Click on the image to go to Tweet. After the Dana de Valencia there were those who took advantage of chaos to make looting and take home batteries, sports material, telephones or consoles, for example, sometimes even with truck help. Only the night from October 30 the National Police arrested 39 people During a surveillance campaign in commercial areas and weeks later, in mid -November, the number of detainees for looting in the areas affected by the rains over 400. It is not even necessary that an event as devastating as the DANA of Valencia occurs. In 1977 New York lived An electric cut which lasted for a day and resulted in a “night of terror”, in the words of the magazine Timewith the looting of more than 1,615 storesmore than 1,000 fires, around 4,000 detainees and hundreds of injured police. A few weeks ago Before a mass blackout also affected much of Chile, the Buric government chose to decree the state of exception and imposed a curfew between ten and six in the morning. In Spain the authorities also chose reinforce securityalthough without reaching such drastic measures. The Government Precise that between Monday and Tuesday they deployed through the country More than 30,000 agents of the National Police and Civil Guard, to which other forces of autonomic and local bodies are added. Click on the image to go to Tweet. In Catalonia Los Mossos d’esquadra They lengthened shifts and activated a night security plan with something More than 7,200 agentswhile there were cities that also increased their local endowments. In Vigo The mayor said Yesterday that the Local Police would triple their efforts and at night 13 municipal patrols would be deployed, to which almost twenty nationals would be added. What has been the balance? A relative tranquility. At least if one takes into account that, although part of the country began to recover electricity within a few hours, there have been cities that took More than 14 hours in having light and the day was marked by Communications problems and traffic lights. The total alert balance is not yet known, but inner speaks of a “quiet night and without remarkable incidents of security or public order” and both the Mayor of Madrid like that of Barcelona They have highlighted the “civism” of their neighbors. “The Madrid have shown that they give their best in the most difficult moments. In front of the blackout, a lesson of civility,” Almeida presumes. That does not mean that the last hours have been An oil raft. Eldiario speaks Of robbery attempts, activated alarms and “some” burning containers in localities of Andalusia and in the city of the emergency services had attended in the afternoon Double of calls of the usual, although Many incidents They were related to people trapped in elevators or people with mobility problems. In Other cities From the country and less inhabitants, the dripping of notices to the authorities throughout the day was also intense. The most graphic answer He has given it However, this morning, Mayor José Luis Martínez- Almeida when they have asked him about how the night had gone in the capital, in which, he says, only a reysta and a launa was recorded. “Quieter than anyone”, summarizes the councilor from Madrid.

Meanwhile, some players have been dealing with problems in their graphics for months

by

More than three decades ago, three engineers sat down to talk in Silicon Valley with an idea that would end up transforming the video game industry. Jensen Huang, Chris Malachowsky and Curtis Priem wanted to create a chip that would improve PC graphics. From that meeting Nvidia was born, and with it, the GPU as we know it. For years, the name of Nvidia has been synonymous with gaming experience in PC. If you have ever set up a computer to play, it is very likely that your graphics card will carry its logo. The brand has achieved something more difficult than technological innovation: build a faithful community that continues with enthusiasm every new release. Lately, however, something has changed in that relationship From the arrival of the RTX 50 series, with models such as The RTX 5090 and the RTX 5080complaints have been increasing. Many users have detected Failures in the controllersand the solutions do not finish arriving. In some cases it is possible to return to an earlier version to overcome errors, but those who have the most recent graphs do not have that possibility, since RTX 50 models are not compatible with the most stable previous versions, such as the 566.36. Reddit has become the center of complaintswith threads that accumulate testimonies of frustrated users. YouTube has also collected the echo of the problem With videos that document the problems. And we don’t talk only about noise on social networks: Nvidia herself has recognized Dozens of mistakes present in their latest drivers, which promises to solve in upcoming updates. Beyond the officially recognized problems, complaints about stability failures are frequent even among users of previous generations. Several players have reported black screens, unexpected reset, flickering, visual artifacts, load errors and forced closures in titles such as’Cyberpunk 2077‘ either ‘Star Wars Outlaws‘. The headquarters of Nvidia in Santa Clara, California Certain failures are related to specific configurations, for example, when using monitors with high soda rates, G-SNC activated or determined Displayport outputs, which complicates its diagnosis. All this comes after a premiere with stupy. Some RTX 5090 feed cables They have presented overheating. In addition, shortly after launch, some users detected that certain graphics cards of the RTX 50 series They had a lower number of rop units Regarding official specifications. Nvidia has confirmed that it is a manufacturing defect that affects less than 0.5% of models such as RTX 5090, 5090d, 5080 and 5070 TI. According to the company, the average impact on performance is 4% and does not affect artificial intelligence or calculation tasks. Nvidia main page in April 2025 (left) and in September 2018 (right) Meanwhile, the role of graphics in the Nvidia ecosystem is changing. They are still important, but they have stopped occupying the center of the stage. The company’s focus is now in artificial intelligenceand that shows not only in its public statements, but in the design of its website, which is far from what it was in 2012 or even in 2018. It is not the first time that a great technological is reconfigured. Microsoft, for example, had its nucleus in Windows for years, But it has diversified its portfolio of products and business units. That decision has been one of the keys that They have allowed him to stay competitive over time. Something similar happens with Nvidia. Founded in 1993, it continues to grow, it is still present and part of its solidity is due to the strategic decisions it has taken. With mistakes, with successes, but always in motion.

The most viral success of AI is at the same time a symptom of its problems as a daily product

by

The AI ​​had ceased to surprise us. And then the “ghiblation” of images and the Internet arrived He went crazy. In recent days we have lived a fever for converting all kinds of images –And even videos– To imitate the style of Miyazaki teacher and the mythical creations of his Studio Ghibli. The phenomenon has served to make AI at least for a few days again. And that is precisely the problem. Saturated from AI. The appearance of Chatgpt in November 2022 has unleashed an explosion of AI, but after the initial earthquake things have relaxed. Although there have been notable advances, we have “accustomed” to AI, and technology seems relegated to the background for most users. As my partner Javier Lacort said in his reflection of a few days ago, we have seen ourselves immersed in “an universe of impenetrable jargon that was moving the conversation about AI from the initial astonishment to arid technicism.” AI lives from “magical” moments. We saw it with Deepseek A few months ago, and we see it again with the Studio Ghibli style images. Until those “magical” moments occur, the AI ​​does not just set among the general public. There is certainly a moderate use among the population and there are also niches that use it intensively –The program of programmersfor example – but people lack something crucial: an App. What do you use AI? The current options are undoubtedly striking in the creative field and also as assistance for professional tasks, but for now the chatbots have not infiltrated our lives as they did for example internet search engines. They solved a more pressing problem – finding what one was looking for on the Internet – but for the moment AI does not have just replaced them and is not used massively. Looking for an AI that is a google for daily use. The search engine revolution is probably one of the inevitable conquests of the future for AI. We are seeing it with perplexity And the search engines that OpenAi so much Like Google itself They are offering users. These platforms will not totally move to the traditional search engine, but one thing is evident: every time we look more with Chatgpt ” – or any other chatbot – and the growth of that trend seems unstoppable. At the moment Gartner’s cycle of expectations is very well reflected the AI ​​phenomenon. It seems that we have reached the peak of oversized expectations, and we now fall into disappointment avism. Source: Wikimedia. Beware of disappointment abyss. The Association for the Advancement of Artificial Intelligence (AAAI) published these days these days A study conducted by 24 researchers from AI. It included a section entitled “Perception of the AI ​​VS reality”, and in it there was talk of the well -known cycle of expectations of Gartner. The consultant itself estimated that expectations and Hype For the generative AI had already exceeded its highest peak. AI is not so much (for the moment). 79% of the experts surveyed in that study indicated that the current public perception of AI capacities do not correspond to the Reality of research and development in this field. In fact, 90% claimed that this is conditioning the investigation, and of that figure 74% revealed that the areas in which they are being investigated are areas where there are still many expectations. So we are not going to get to the AGI. The most important companies in this area have a common goal: to achieve a AGIthe Holy Grail of Artificial Intelligence. However, these same experts do not have too much hope that we will develop it. 76% of the 475 respondents indicated how to climb (more data, more GPUS to train models) will not be enough to reach an AGI. We need a different approach, and those experts advocate prioritizing issues such as security, ethical governance and a gradual and more responsible innovation instead of this apparent frantic career that does not think about the consequences. Waiting for the next Bombazo of the AI. The fever for “ghibliization” seems to have relaxed significantly and surely in a few days or weeks it is blurred as a striking option more than one AI that excites us to pull – before the Grok 3 censorship imagesfor example – but do not conquer permanently. At the moment it seems that this will continue to be the norm, and now we are waiting for that next pull and perhaps that Killer App that can mark a turning point in the adoption of AI. OpenAI and his rivals need Hype. Meanwhile one thing is evident: what companies sell us (“we are close to the AGI” or “with AI you can do everything Better and faster“) is away from reality. They sell expectations and Hype. TOI remove the best example is OpenAi, which needs that message to continue raising Gigantic investment rounds that allow you to continue burning money As if there were no tomorrow.

It is a sign of all the problems that corner the Tagus basin

by

Yesterday, the Manzanares S riverIt could significantly The high risk threshold of overflow in Madrid. It is not just an “alert”: the river It has overflowed In the brown, the connection branch between the M-30 and the M-40 was cut for hours, but there are Almost another dozen roads that are still cut by the storm. As it happened In Seville a few days ago, In Guadalajara last week either It is happening in Toledo Right now, it is very striking. Above all, because it is something that goes far beyond Manzanares. What is happening? What are we seeing? And it is that the Manzanares is only a sign of endless problems that face the basins of the Tagus and that of the Guadiana: rivers that usually carry very little flow and that, suddenly, channel a huge amount of water. And, as we said yesterday, the problem is never just the water that falls: the problem is, above all, that water has to go somewhere. But it is not easy. For many reasons: the first is that ‘natural’, these types of floods are usually accompanied by landslides, phenological realignments and other geological phenomena. The rest, unfortunately, are of human origin. For decades, we have been building around the channels as if the water they carry out all the water they can carry. We have narrowed the alluvial plains, we have built In flood areaswe have raised concrete structures that today (with these accumulated) are unable to contain the strength of the rivers. Manzanares is news because it is in Madrid, yes; But it is also news because it will affect hundreds of thousands of people; And, above all, it is news because it is a very clear example of what is happening in the center of the Peninsula: problems, many problems. The great paradox, again. As We said a few days agothe great paradox that brings us climate change is that we have to prepare to survive periods of increasingly long and intense droughtwhile we plan infrastructure and plans against increasingly intense floods. Talavera is a good example. According to the Center for Public Works Studies and Experimentation From the Government of Spain, the average flow of the Tagus in March as it passes through the Toledo city is 188 m3/s. Right now it is 750, now has overflowed at many points and the City Council is convinced that it will be up For the rain. And what do we do? That is the big question. Because, As the meteorologist Jordi Carbó explained“We have fallen into a difficult dynamic to break.” Although it is true that the ECMWF Start drawing some deceleration of rainfall, “forecasts prologize the rains until the beginning of April.” That is, “it is very likely that in this month of March there will be excellent precipitation records” and, in a context in which March It is becoming more and more rainyit is crucial to take it into account. But right now it only remains to remember. Today the urgent is to take action, displace people who can be affected and contain the damage. Tomorrow the important thing is to take it into account and put ourselves to work so that the next flood caught us prepared.

This Seoul bridge seems ordinary, but stars one of South Korea’s biggest problems: suicides

by

South Korea is a country that advances by leaps and bounds in technological question. It is home to some of the most important companies in the world -Samsung or Hyundai- and He is fighting To become one of the referents in the chips segment. Seoul, its capital, is a look at what could be the future of cities hypertecnologicalbut after that image of modernity, an increasingly silent pandemic is hidden: that of suicide. And no place better reflects this crisis than the Mapo bridge in Seoul, nicknamed ‘The Suicides Bridge’. Alarming figures. Suicide is a taboo issue in many societies that sometimes have not paid attention to avoid the tragic outcome. It is not something that Pille so far. In 2020, in Spain it committed suicide One person every two and a half and a half. Each country Try to deal with your way With this situation, but the case of South Korea is bleak. Do not go to the archives to see the evolution of suicides in the Asian country: In 2021, 13,352 people committed suicide. In 2022, approximately 13,000 were given. In 2023, the figure rose to 13,770. In the first six months of 2024, 6,375 people committed suicide, assuming a increase of more than 10% compared to the same period of the previous year. He total It was 14,439 dead. Cocktail. They are figures distant to the maximum of 2013, when 14,427 occurred, but in 2020, the country had the highest rate among OECD countries with 24.1 suicides per 100,000 inhabitants. It is more than double the average. The reason is that there is a social and cultural cocktail that pushes thousands of people to end their lives. There is one very high social pressure and competitiveness for being the best in studies and work life. If you do not achieve it, economic problems occur, but although that ‘success’ is achieved, there is a high level of stress and low social awareness about mental illnesses. Also idealized and impossible beauty canons for much of the population. And it is not something that cares only to suicide, since the scarce birth that is taking the country to an unsustainable situation is also the gross of those social pressures. THE MAPO BRIDGE Effect called. The most affected group is the one between ages of 10 to 39 and is the major Cause of death among South Koreans between 10 and 39 years. Between 40 and 56% of deaths in these age groups is due to suicide. These brutal pressures even affect celebrities of the country, so much that studies have already been carried out that relate the increase in suicides with the moment in which one of these celebrities ends with his life. As if there were an effect called or idealization of the act, three of the eleven cases of suicides between celebrities resulted in an increase in the rate among the population, leading people to use the same methods as said celebrity. In recent years, there have been numerous cases among young Astros of K-Pop, cinema and television, very exposed to criticism in a country where there is a very strict moral standard that these celebrities must meet. The notice says: “Line Life. Methods. They have gone changing These last years. At the beginning of the century, most used pesticides to get intoxicated. This poisoning remains one of the most used methods, but now it is through burning YoTan: Carbon cylinders that produce poisoning by carbon monoxide aspiration. The hanging has also become common (with examples such as’Sulli‘That they expose that effect called), but throwing themselves to train tracks or from bridges is also a method. THE MAPO BRIDGE. And all this leads us to the Seoul bridge. We have talked about Many bridges in Xataka And Mapo’s is, structurally, a normal bridge, almost ordinary. It does not stand out for design, certainly, but it has become the sad secondary protagonist of dozens of suicides in recent decades. It is not the only one from which the South Koreans throw themselves to end their lives, but one of the most used due to the current of the river has very difficult the rescue work very difficult. So much is the impact of the bridge on the statistics of the country that began to call colloquially as ‘The Suicides Bridge’. From the city, this was wanted to combat the structure as ‘bridge of life’ as part of a Samsung Life Insurance initiative. But it was not a simple name change. Measures. The company placed photos of happy families, among other measures to deter suicides, such as movement sensors that activated light posters with mood phrases, but they were considered a failure In 2015 and that was when the focus was changed to prevent suicide instead of deter. Thus, a series of active and passive measures were installed to stop the high rate of vacuum throwing, such as phones from which to request help every few meters (it has a length of about 1,300 meters), mirrors so that those who plan to jump see their face, cameras, high barriers and rollers that make it difficult to get to the edge. The fences are high and in the last upper section there is a roller We can see the roller, as well as the mirrors Social strategies. It is, in short, a series of actions to make jumping more difficult, but beyond this (which is still a patch), in recent years the country has taken the mental health of citizens more seriously. For example, strategies to prevent suicide thanks to greater media coverage than public awareness, as well as training campaigns and notions of suicide prevention for teachers and social workers. Also reviews focused on adolescents and another series of infrastructure measures to strengthen security on bridges and train tracks. Despite the efforts to reduce the incidence of suicide, the Mapo bridge remains a symbol of this crisis, with 846 people jumping From the bridge between 2014 and 2018, … Read more

AI is already our best ally to solve the mathematical problems that seem impossible

by

The applications of the artificial intelligence (AI) are presumably unlimited. Beyond the daily uses with which many of us are already familiar with the design of drugs, Disease diagnosisthe OPTIMIZATION OF INDUSTRIAL PROCESSES or the Analysis of physical or chemical mechanisms complexes, among other options. It is even being used to solve mathematical problems of enormous difficulty. In addition, algorithms that use deep neuronal networks and Automatic learning They are designed to identify complex patterns in large volumes of information, which allows them to recognize images, voice or process natural language greatly. AI has reached our lives, and it is clear that it will stay, but the most surprising thing is that it is consolidating as an extremely valuable tool in relatively exotic fields. It is possible that AI helps us solve the mathematical problems of the millennium In October 2024 Goal AIMeta’s artificial intelligence, managed to generalize Lyapunov’s function. The Russian mathematician Aleksander Lyapunov proposed the concept of the function that bears his name in 1892. His work is a very important tool in the study of dynamic systems, but mathematicians have since struggled to find a general method that allows identifying the functions of Lyapunov. And they have not been successful. However, goal has had it. Our mathematical knowledge will no longer be limited by intuition and human capacity The strategy used by the company led by Mark Zuckerberg to solve the challenge of Lyapunov’s functions has consisted of training an AI model to recognize patterns and relationships between certain dynamic systems and its corresponding functions of Lyapunov. This is precisely what is good for AI. And it is a huge success because our mathematical knowledge will no longer be limited for intuition and human capacity. The AI ​​puts in our hands a new way of addressing complex mathematical problems, identifying patterns that a priori remain hidden for the human being. However, in the field of mathematics AI still has to improve to help us solve the great challenges that the human being has ahead. Sergei Gukov, professor of theoretical physics and mathematics at the California Institute of Technology (Caltech), leads a team of researchers who is looking for ways to use AI to solve advanced mathematical problems that require thousands, millions, or even billions of steps. These scientists are currently working on The conjecture of Andrews-Curtisa group combinatorial theory proposed 60 years ago. They have not yet managed to solve the main conjecture, but with the help of AI they have achieved something important: they have refuted several families of problems related to the conjecture of Andrews-Curtis and known as counterexamples that have remained open for more than 25 years. Gukov acknowledges that Current AI models have important limitations When facing very complex mathematical problems, but you hope that in the future this technology allows the human being to solve Mathematical Millennium Problems. According to this mathematician, the best asset that researchers have to face this challenge is to instruct AI by resorting to Reinforcement learning.

Problems between US and Taiwan governments begin. And the chips industry is at the center of everything

by

The government led by Donald Trump is determined to do everything necessary for the US to recover leadership in the semiconductor manufacturing industry. At the moment In Asia they are manufactured 90% of memory chips, 75% of microprocessors and 80% of silicon wafers. However, the most outstanding country in this continent in this sector is Taiwan, with a production of 90% of high integration chips and 41% of microprocessors. The US administration is already taking the necessary measures to promote US companies to buy integrated circuits manufactured in the US. The tariffs you are approving They largely pursue this objective, and, despite the alignment in the geopolitical field that support the US and Taiwan, the manufacturers of Taiwanese chips are not at all safe from the tariffs. In fact, Donald Trump made a statement at the end of January which he exposes his intentions with total: “In the very close future we will impose tariffs on foreign production of computer chips, semiconductors and pharmaceutical products to return the manufacture of these essential goods to the US (…) went to Taiwan; now we want them to return. We do not want to give them billions of dollars in the ridiculous driver program. They already have billions of dollars. incentive will be that they do not want to pay a tax of 25, 50, or even 100%”, The current US president declared. The Taiwan government is putting limits to TSMC The express mention to Taiwan that the US president has made is a very clear allusion to TSMC. On this Asian island there are other semiconductor manufacturers, such as UMC, but its relevance in the chip market is much lower than that of the company currently leading CC Wei. TSMC dominates the integrated circuit market with A quota of approximately 60%so your leadership in the chip manufacturing industry is indisputable. Anyway, the step forward that the US administration is not going to take TSMC by surprise. This company has been outlining its strategy for more than four years to extend its semiconductor manufacturing infrastructure Beyond Taiwan’s borders. And he is doing it for two reasons. On the one hand it is an effective way to protect your business if at any time it is triggered A war conflict between China and Taiwanand their plants on the island were useless. TSMC is preparing an offer to control the integrated circuit manufacturing plants of Intel But, in addition, TSMC is significantly developing its infrastructure in the US. His plan is that their new Arizona factories not only serve to protect their business from a possible conflict between China and Taiwan; They also protect it from US tariffs. This is not all. Although there has not yet an official confirmation of this information, according to The Wall Street Journal TSMC is preparing an offer to Control manufacturing plants Intel integrated circuits. It prosper or not, at the current situation this strategic decision makes sense. And it has it because it would allow TSMC to definitely consolidate its semiconductor manufacturing infrastructure in the US, as well as be present in countries where it now does not have production plants. However, The Taiwan government does not see this possibility with good eyes. Its economy depends deeply on its chip industry in general, and TSMC in particular, so the US ambition to recover its leadership in this sector directly enters into conflict directly with Taiwan’s survival as it is currently. Kuo Jyh-Huei, Taiwan Economy Minister, has warned TSMC in a resounding way: “No one can shake the foundations of the Taiwan semiconductor industry. We must have confidence in TSMC, and the government will fully support the ‘sacred mountain’ that protects the country (…) so that TSMC expands its global presence and establishes a joint company in any location, definitely needs the government’s permission.” It is evident that the possibility that TSMC acquires such a solid production infrastructure outside Taiwan is detrimental to weight That has this island in the sector that feeds it. Right now we cannot assume that TSMC will control Intel plants, but we can be safe: 2025 will be a very exciting year in regard to the development of the integrated circuit industry.
