impossible

If the question is when the next blackout will occur, the answer is simple: it is impossible to know

by

He Bru what last April 28 It has generated many questions, and among them a couple stand out that seem inevitable: the first, if there are possibilities that it will produce again Another massive blackout. The second, if any, when will it happen? It is impossible to answer these questions with total certainty, although there are ways to reduce those possibilities to the minimum possible. Impossible to respond to that. To Niehls Bohr, the father of quantum physics, the phrase “making predictions is very difficult, especially when it comes to the future” is attributed. That also happens when trying to predict A nearby potentialsomething practically impossible and what also contribute several arguments. We still do not know the origin of the blackout. One of the problems of trying to answer that question is that we have no definitive or officers about what caused the blackout. From the Spanish Electric Electricity (REE) it was stated that the blackout It was due to a generation disconnectionbut they still do not give details about the specific causes that caused such disconnection. The experts They point to renewables As a possible cause, but at the moment nothing is confirmed. And without knowing the origin of the problem, we cannot know how to avoid it in the future. An unfortunate prediction. Pedro Sánchez, a jacket but without a tie, appears at a press conference. At a given time he says that “there will be no electricity blackouts.” The videowhich has now gone viral, it is not these days, but of September 6, 2022. At that time those words were pronounced in the context of a possible Russian gas cut throughout Europe. But there has been, and the question is whether there will be. The president of the Government was wrong in his prediction. Two and a half years later Spain has suffered The biggest blackout in its historyand one of the great questions that citizens have been asked is when the next blackout will occur, If it occurs. Never say ever. The research of the causes will lead to means for something like that not to happen again. The President of the Government spoke In your appearance of April 29 that there would be reforms so that “never” a generalized electric blackout is repeated like that of April 28, but even with all these reforms and measures zero probability does not exist. There are impodeables. Even in the case of detecting and correcting the problem caused by the blackout, it is still impossible to ensure that another will occur in the future. There are of course possibilities that a technical, human error or a natural catastrophe poses blackouts at some point. Spain has improvement margin. As we have commented In Xatakathe Spanish energy mix needs a stabilization system of the robust network, but also the Iberian Peninsula is an “Energy Island With very little international connection. Thus, we need an integration stronger With the rest of Europe to balance demand, strengthen system safety and share surpluses. There are other possible measures that can be taken, and as explained by the analyst Javier Blas In Bloomberg“The design of the network, policies and risk analysis are not yet up to the management of excess renewables.” All this is important when minimizing the risks of another future blackout.

Elon Musk’s ambitions were impossible to comply

by

Tesla has presented results. And they have been so bad in this first quarter of 2025 that it would be necessary to travel four years ago to find similar figures. There are various reasons but Elon Musk’s ambitions and promises are having their direct consequences on the company. An entire life. Four years for Tesla is a whole life. The company has been growing at a devilish pace until last year. But 2024 already closed it with sales lower than the previous year despite do everything possible to avoid it. In the first quarter of 2025, the benefits have fallen to just over 400 million euros, 71% less that in the same period a year ago. You have to go back to 2021 to find such a low figure. The problem for the company is that, then, it sold one less car (the Cybertruck was just a promise) and still did not reach one million units sold. That is, going back four years for Tesla is to go back a long time because the company was very different. A 2025 to shake. The first three months of the company have been really bad. To the point that They would have lost money If not for the Sale of regulatory credits (The payment made by other companies to meet in the average emissions by submitting to the regulators under the same group). In the absence of knowing to what the update of Tesla Model and is directly affecting its sales, the truth is that the company is leaving huge falls in countries like Germany or Francethe ones that sell the most electric cars in Europe. In the German country, in fact, they reach 60% fall. At the same time, their actions have collapsed and right now they cost half that in December 2024. This future of the actions must be taken prudence since they are intimately linked to the figure of Elon Musk. In fact, despite the bad results, the confirmation of the company’s CEO to abandon part of its governmental tasks to focus on Tesla has raised its price by more than 10%. Musk. Will reduce your work in the United States government “significantly”. This has been the word used by Elon Musk to quantify the amount of hours he will stop using in front of Doge (the department that leads within the State) to dedicate it to Tesla. This task has been, for some investors, the reason why the company has shipwrecked in recent months. For others, such as The New York Timesit is evident that there is damage to the company’s image with the statements and gestures of Elon Musk. The anger of those who have promoted BYcots to the Company They have focused, above all, to highlight the attitude of their greatest shareholder. A low profile in the government can be understood as a longer time dedicated to Tesla or as a lower public exposure and, therefore, a less worn image. The first interested, in fact, It is Musk itself whose fortune depends largely on the future of Tesla. But not everything is political. It seems unquestionable that Tesla’s image is irremediably associated with the figure of Elon Musk. He Financial Times He came to qualify the owner of the company as “demolition ball.” But there are other edges that deserves to stand before accusing Musk’s political drift as the only guilty of the bad results. The model hangover and. Something that explains the low sales of Tesla is that Tesla Model and has been renewed in the first weeks of 2025. Several factors must be taken into account: The lines have had to be renewed, so production has been reduced. Until in a few months we will not know how many possible buyers were waiting for the update before formalizing the purchase. To sell the Tesla Model and in stock, great discounts and very attractive financing have been applied, greatly reducing the profit margin. In the coming months we will begin to see how much the update of Tesla Model is interested and in front of the competition. In 2024, Tesla sold 1.77 million cars in the sum of the Tesla Model 3 and Model Y. of them, 1.09 million were represented by the electric SUV despite the fact that it was already known that the car was going to be renewed. Any mishap that hurts Tesla Model sales and is, right now, a problem for the company since half of sales are from this car. A cybertruck that is failing. Another of Tesla’s great problems and, probably, its greatest commercial failure. He Tesla Cybertruck He promised to be a supervent. The volume of reservations I encouraged to think about the car in these terms. But After the first feversales have collapsed to the point that analysts talk about the company will only produce 55,000 units a yearcompared to 250,000 promised units. Tesla had the opportunity to Make your cybertruck an aspirational vehicleof low production and great benefit that will report benefits in brand image. However, he has starred Memes on social networks And above all, Review calls have been continuous for all kinds of reasons, damaging its value. To the point that the company already seeks a solution to place thousands of them in markets outside the United States. The car that never comes. At the same time, Tesla and Musk have been promising for years An electric car of $ 25,000. One that has been impossible for the company to sell. If we do not have an electric car of $ 25,000, it is simply because the company has not found a way to make it profitable. In recent months we have known that the alternative will be a kind of Tesla Model and in miniature. But the car should arrive as a more affordable option than the current SUV as it would touch $ 40,000, according to The Wall Street Journal. In the same terms it was expressed Reuters Recently and in … Read more

It seemed an impossible enemy, it was actually the brightest antipyretary system in a video game

by

Piracy and entertainment are two concepts that They go hand in. In video games, this has meant a kind of race between the cat and the mouse, with the video game companies pulling inventiveness to try to pay players paying for their products. At the moment, Denuo is a very safe tool – that not invulnerable -, but throughout history we have seen most imaginative antipyertería systems. And the most memorable case is that of ‘Serious Sam 3‘. The reason? A giant and implacable scorpion that was looking for you to end with you if it detected that your game was a pirate. And the players accepted the challenge. Aid! It ran 2011 when the Croatian Croteam team (their heads did not break a lot) launched the third installment of its hilarious shooting saga ‘Serious Sam’. At that time, the antipyertorous measures were so rudimentary that the game came out ‘cracking’ within a few hours of the official launch, so many users quickly made a copy. Except in some cases in which mouth to mouth causes peaks of players months or years after the launch of a title, it is usual for forums and social networks to fill out of comments on a newly released game. As a minority, there will always be players commenting on the levels, which seems to them the game and reporting problems. And shortly after the launch of ‘Serious Sam 3’, the players began to complain about something: a Red scorpion that appeared in his departure and prevented them from continuing with the game. Even recently They published Some complaints in Steam. Scorpion. These players described the scorpion as a huge, invincible, very fast entity, that shot incessantly, that it was a sponge of bullets and that did not leave you alone at any time and complained about what they believed was a bug or a programming failure in the game code. The enemy’s pint is quite terrifying, which added to his fire power and the fact that it is invincible … well, it was not a pleasant drink. The little girl is that it was not a bug, but a characteristic of the game. Croteam knew that it was impossible to put doors to the field and that his game was going to be pirated, so he scheduled the game with a special characteristic: if he detected that the copy was a pirate, the invincible scorpion appeared and it was not going to stop until he killed the player. It was impossible for the player to enjoy the game in those conditions. Praise. In the video we left for some paragraphs, we can see an example of how the community took this movement. “Simply, I adore Croteam. They are not the details that the study has added to the game. No, no, no. It is the introduction of an arachnid, immortal and very fast enemy that is part of its antipirable system. And it is the icing on the cake.” That was the description of the shared video just a month after the launch of the title, but in the comments we can see dozens of players who reacted in similar ways. Comments such as “It is the best antipirable system in history”, “The movement of the bug terrifies me”, “Do not annoy, have applied antipiría measures either for once. This is comedy in its purest form” or “This is how the DRM should be. It has no negative effects for legitimate players, but hilarious consequences for pirates” show that the system was not badly received, at all. And, among all praises, only a few commented things like “expect, that pirates have extra difficulty? That is not fair.” And there were those who accepted the challenge. And the ‘Commission’ arrived. Thekotti He is a player who has been going up for years Speedruns to your YouTube channel. It has some absolutely demential and a few years ago raised a video passing in just over half an hour ‘Serious Sam 3’. A time later, he assumed the challenge of Croteam and went up A new Speedrun of the game, this time with a brand of one hour and 14 minutes until the game is completed. Why 45 more minutes if he was already an experienced player? Because he played the version with…. Scorpion. The bug took little to appear, but Thekotti was so fast that the scorpion had to reappear in front of him every two by three. With what has been learned, he tried again, lowering his brand until the time and six minutes. Seeing the video is a show, especially because that terrifying measure is nothing: Mods to activate it in legal copies. Obviously, this is not how most players enjoy the game, but it must be said that this movement by the Croatian study liked it so much that it inspired the Creation of Mods so that players with legitimate copies of the game could introduce the relentless scorpion in their games. I have to comment that I was never interested in the saga, but when I learned about the existence of this, I downloaded the pirate game, I laughed for a while, I checked that the bug was superman and bought the game in the first Steam sales in which it was available. In this case, I can say without fear of being wrong that it is one of the best ideas to discourage piracy, unless a PROPLAYER He gets in his head play your game without care of these measures.

Physicists believed that this quantum phenomenon was impossible. They were very wrong

by

This appointment of Richard FeynmanNobel Prize in Physics for their contributions to quantum electrodynamics and one of the most admired scientists of the twentieth century, condenses very well The complexity of quantum physics: “If you think you understand it, you don’t really understand quantum physics.” Quantum mechanics study the laws that govern The world of the very smallof the particles, as well as the interactions to which the atomic and subatomic structures are exposed. Most of these rules are radically different from the laws we have become familiar with in the world in which we live. In the macroscopic world. Many physicists have spent the last century trying to understand how known quantum phenomena work, and also striving to identify unknown quantum rules. The problem is that working with the extremely small, with the particles, is very difficult. However, this does not mean that they are not successful. To hunt and capture the elusive transition of super -artedia Physicists Klaus Hepp and Elliott H. LIEB predicted in 1973 a quantum phenomenon known as super -transiant phase transition. For more than half a century the scientific community has worked out without success to find evidence to protect the existence of this mechanism beyond mere theory. But everything changed on April 4. That day a group of researchers from Rice University, in Texas (USA); the University of Shanghai (China); NASA’s National Laboratory (USA) or the National University of Singapore, among other scientific institutions, published an article in Scienceadvances in which he explains the procedure he has used to experimentally observe this quantum phenomenon so elusive. Understanding what is the transition of super -transiant phase and all its implications is not simple, but we can get a rather precise idea about what this mechanism consists of if we observe it as a sudden change in a particle system that causes many of them begin to behave in a coordinated way. When this phenomenon does not occur, atoms interact in a weak way and behave in a disorganized way, but when the super -artary phase transition arises, they synchronize and exhibit the same behavior, giving rise to a new state of matter. When the super -transiant phase transition arises the atoms are synchronized and exhibit the same behavior The most surprising thing is that this new state gives the material unusual properties from a macroscopic point of view. The researchers who have mentioned some lines above have managed to carry out the first direct observation of this mechanism. And they have succeeded by triggering the transition in a glass composed of erbium, iron and oxygen subjected to a temperature of −271.7 degrees Celsius. In addition, they exposed it to a magnetic field of no less than 7 teslas, so it was more than 100,000 times more intense than the magnetic field of the Earth. What they pursued was to induce the transition of super -transiant phase by coupling the spin of the particles. And they succeeded. The spin is an intrinsic property of The elementary particleslike the electric charge, derived from its time of angular rotation. The first experimental evidence that endorsed its existence It arrived in 1922 Thanks to the experiments of German physicists Otto Stern and Walther Gerlach, although scientists did not begin to understand the nature of this very important property of elementary particles until a few years later. The reason why it is not easy to understand precisely what the spin is because it is a quantum phenomenon, so it is not quite correct to describe it as a conventional rotation movement in space. Even so, the description that I have proposed in the previous paragraph is usually used for a didactic purpose because it helps us to intuit without too much effort what we are talking about. In any case, the most interesting thing is that the transition of super -transiant phase opens the door to the next generation of quantum technologies. This is the really important thing. According to physicists involved in this experiment, this mechanism can be used to put quantum sensors endowed with a much higher sensitivity than those currently available. And it can also be used to produce more robust cubits for Quantum computers. Sounds good. I hope your predictions are fulfilled.

His reasoning models finally do what until now was impossible for them

by

For more than half a year, users of Chatgpt – and also those of the API – we have access to two types of models: the GPT models, such as GPT-4Oand reasoning -oriented models, such as O1. The problem is that, until now, we were forced to alternate between them for tasks that require complex thinking, web navigation or interpretation of images. As of today, that begins to change. New models on stage. O3 and O4-mini models, presented this Wednesdayshorten distances with GPT models. For the first time, reasoning -centered models access tools that, so far, were exclusive to classic models. Namely: Analyze images (and think with them). Analyze files. Generate images. Navigate the web. Do research. Use advanced voice mode. The keys to “visual reasoning”. The interesting thing is not that O3 read what is in a photo. It decides how to look at her. He knows if he has to turn it, expand a detail or ignore the irrelevant. That process is now part of its reasoning chain. He does not describe an image, but “think” about it to give us a better answer. A remarkable jump. We are facing a series of improvements that the most demanding users will undoubtedly know how to appreciate. The reasoning models, it should be remembered, “think” before responding. They generate an internal chain of thought before offering us an answer. They are not the best option for those looking for texts with literary dyes or quick responses on any subject. But they are ideal to code, reason scientifically and plan complex workflows, especially in environments where several steps are involved and Agents. Taking this into account, and as expected, Openai has also improved the main capabilities of these models, making them more capable and precise. OpenAI O3: This model achieves a prominent performance in Swe-Bench verified (without customization), a test that measures coding skills, with a score of 69.1%. According to OpenAI, in evaluations carried out by external experts, O3 makes 20% less important errors that OPENAI O1 in difficult real -world tasks. OPENAI O4-MINI: It offers similar yield, with a score of 68.1%. To put it in context: O3-mini obtained 49.3% in the same test, while Claude 3.7 Sonnet reached 62.3%. This model is optimized for rapid and profitable reasoning, and yields especially well in mathematical, coding and visual tasks. The model that was not going to launch. OpenAi has changed their minds. In February, Sam Altman ruled out launch O3 as an independent product. But just a few weeks ago, toHe gave a “change of plans”. This turn materializes today with the arrival of O3 and O4-mini, the new models that mark a new chapter in the company’s strategy. On the way to chatgpt. From today, users of Chatgpt plusPro and Team can already start using O3 and O4-mini. In the coming weeks, O3-PRO will arrive, a more powerful version of the reasoning model, which will be available for subscribers of the Pro Plan. Meanwhile, these users can continue working with O1-PRO. Images | OpenAI In Xataka | Openai’s hypothetical social network does not want to connect people. Want your data to train your AI

The US is realizing that manufacturing the iPhone without China is almost impossible. Tariff exemptions are the test

by

Donald Trump’s administration has applied a very special exemption to reciprocal tariffs announced The last days. Thus, mobile phones, computers and some other consumer electronics products “are fought”. Importing them to the United States will not make 10%global tariffs apply, nor China’s specific ones, which are 125%. What products are exempt. The note published by the US Customs Department almost without making noise is especially important, and makes a list of HTSUS codes (Harmonized Tariff Schedule of the United States) that include different types of electronic products. Among them, exemptions affect: 8471: PCS of desktop, laptops and its components, such as CPUS, hard or I/O peripheral discs as monitors (8528.52.00), mice and keyboards 8517.13.00: smartphones 8517.62.00: Routers, modems, wireless access points 8523.51.00: SSD units 8524: CDS and DVDS Regrabable 8541.49.10 and 8541.49.70: Solar panel cells 8541.49.80: LEDs 8542: microprocessors, controllers, memory chips and other integrated circuits But they are temporary exemptions. As they point out In Financial TimesUS Secretary of Commerce, Howard Lutnick, made it clear that these exemptions are temporary. All these products will be part of the semiconductor tariffs, “which will probably arrive in a month or two.” Trump denies that this are exemptions. In his social network Truth, Donald Trump He also stood out That what was announced on Friday were no exceptions to tariffs and made it clear that these products are still subject to 20% rates related to the fentanil. “What has been stated is that we need to manufacture products in the United States, and that we will not be hostages from other countries, especially hostile commercial nations such as China, which will do everything in their hand to disrespect the US people,” he added in his statement. Dodging price increases. The measure is clearly aimed at avoiding notable price increases in semiconductors, mobiles and consumer electronics products, especially considering that a vast majority of those sold in the United States They come from China. The impact for consumers can be very important, and these temporary exemptions reduce concern for the future of these products and their prices and protect strategic sectors. The iPhone as a great example. Some analysts estimate that the price of the iPhone in the United States It could triple If the cost of tariffs ends up moving to consumers. Apple smartphones are one of the clear examples of how tariffs would affect US consumers first and the rest of the world later. The climb of reciprocal tariffs between the US and China has been spectacular in recent weeks. Source: Reuters China as a US factory. According to Counterpoint Research dataChina represents 80% of the iPhone production sold in the United States. The remaining 20% ​​are manufactured in India, a country in which Apple is gradually growing in production precisely to avoid the dependence of China. The Cupertino company in fact fought several aircraft full of iPhone From India to try to have some margin of maneuver if tariffs came into force. Exemptions also disappear the “basic” 10% tariff that applied globally and included countries such as India. These exemptions are also partly the tacit recognition to manufacture the iPhone in the US It is practically impossible. Business pressure. The impact of tariffs has been especially remarkable for Big Tech, which have collapsed in the stock market in recent weeks. All of them depend largely on China’s production capacity, and these exemptions are also an acceptance (at least temporary) that changing things and mitigating Chinese dependence will take a long time. No official explanation. The US government did not explanations about the reason why it applied these exemptions, but it is evident that This is a big respiteeven if it is temporary, for companies such as Apple, Nvidia, Dell, or HP, which import a good part of their products from China. A war without winners. As they point out In axiosChinese President Xi Jinping stressed that a war of tariffs “will not produce any winner.” China indicated that I was evaluating the impact of these exemptions. In a statement last Sunday, the Chinese Ministry of Trade Califified the measure as “a small US step to correct its wrong practice of establishing ‘unilateral reciprocal tariffs.” How will we be next week? Democrate Senator Elizabeth Warren appeared in a debate In CNN to describe the confusion that exists about tariffs. He indicated that “investors will not invest in the US with Donald Trump playing” red light, green light “with tariffs and saying” Oh, and For my special donors, you have special exemptions“. He also highlighted how the situation is impresable.” No one can imagine what the rules will be within five days, much less in five years. “ Image | Gage Skidmore In Xataka | Spain acts where Europe doubts: the strategy that is paying fruits in China

It seemed impossible for the rains of March to be bad news for someone. Until the watermelons and melons arrived

by

The huge rains of March have left much of the field offside and, for weeks, the generalized response has been the country. It is not for less: in the whole of Spain 149 l/m² have been accumulated2.5 more than usual. The benefits are huge: they are not only full swamps; but the fields of cereal, vineyard, olive grove and nuts at their best and a sweet moment in sheep, goat and milk bovine. But there are also great harmed. Who can water go wrong? Paradoxically, many crops: some vegetables (from broccoli to lettuce), the strawberries of Huelva, the harvest of potatoes, legumes and, above all, to the melon and watermelon. Is it for floods? In large part yes. In Murcia, more than 5,000 hectares of vegetables have been flooded and in Almería crops have been affected (both outdoors and greenhouse). It is thus understood that, during all this time, root asphyxiation has been one of the great fears of farmers. In essence, we talk about A phenomenon that occurs when the roots of the plants do not receive enough oxygen. This usually occurs when there is an excess of water on the ground; And, in fact, it can happen even if the ‘flood’ lasts for a short time. However, there are problems beyond suffocation. A good example is the chickpea. In his case he has not suffocated because, in short, he has not even come to be planted in provinces such as Seville (which concentrates a third of national production). As the Secretary General of Coag Sevilla says in The debatethe chickpea has to be more than 100 days in the countryside and “this year, hopefully, will pass 60”. Even in the event that the meteorology accompanies, the chickpea campaign It will be very bad. And, in addition, it is inevitable because farmers cannot plant anything else: the norms of common agricultural policy They force them to plant a certain percent of its land with legumes. And then we have the humidity. The rain has caused moisture levels to shoot and, With themthe “proliferation of pests and diseases such as the Botrytis (caused by a fungus) or the Mildiu” (groups several diseases that damage stems and leaves) “that are rotting the kills. And what happens to melons and watermelons? Another different thing. In the case of these crops, the situation is “worrying” because the rains arrived in “The most delicate moment, pollination“This has significantly delayed production to the point that seems unfeasible that early watermelons can reach the market on their usual dates. The hope of the sector, As explained by COAGis that great production is rethink. If no unforeseen occurs, that would allow the market of late watermelons and melons with force. But, of course, everything depends on what happens in the next few days. It is worth remembering that in recent years, these two summer fruits have starred controversial for its high prices and distribution problems. All to do. The great unknowns are now two: What water management will allow hydrographic confederations and the rest of the administrations, on the one hand. And how flexible will be the European Union With the restrictions of phytosanitary products In a context climatic extreme. However, there are many more things on the table. Many more problems, many more opportunities. Above all, before The perspective that this is the new normality.

There are a lot of time apps. Know which one that is most accurate is almost impossible

by

You get up one morning. You look at the application of time on your phone. “100% rain,” or so says. You go to the window and there is a scorching sun illuminating the street. Worse is to consult the application of time, that just 10 or 20% probability of rain and, as soon as you leave, you fall a downpour. The latter is what It has been happening in Spain during the month of Marchone of The rainiest in a long time. Although we blame apps not to predict perfectly, the truth is that interpreting them is not as easy as it seems. How time apps work. Time applications work by combining data from different meteorological models to show us what are the rain forecasts for that day. Each of them is based on a different model, depending on the company behind. These models can be global or regional, having the latter more precision in specific areas. In Spain, Aemet operates with different models such as Arome, MM5 or Reion, although time apps can use models outside our country. Apple and Android. Apple’s time app uses information collected by The Weather Channelsince it has Your own API to provide meteorological data to other apps. If we use an android, such as an Xiaomi, your app works with information from Accuweather. This is precisely what makes each app show us a different fact: each of them is based on the models that it considers, and make predictions on their own. For example, use your own prediction system called Accuweather Minutecast, which combines numerical models with artificial intelligence and real -time radar data to offer hyperlocal forecasts. It does not generate its own weather models from scratch, process information from global models. 100% rain. One of the main problems in the time apps has to do with how they show the information to the user. If we see 70% in the app, probably, let’s understand that the probability of raining in our city is 70%, something that is not completely. In fact, the thing is even more complicated if we go to the forecast for hours and there we see that the percentages are lower than those of the total day. Quite difficult. We start from the basis that the weather prediction It is a complex science due to the dynamic and chaotic nature of the Earth’s atmosphere. Factors such as sudden changes in temperature, pressure, humidity, wind patterns and ocean currents interact intricately, creating a network of interconnected processes difficult to foresee exactly. What is “100%”. There is a common common interpretation with respect to the percentage of probability of rain showing weather applications. It is easy to think that a “100% rain” indicates that it will rain throughout the day throughout the area. The truth is that this 100% means that, in similar weather conditions, it has rained 10 out of 10 times. But it is possible that this new occasion does not do it. The percentage does not determine the rain that will fall, but the statistical mark of how frequent it has been raining in similar conditions. The best way to measure it. The time apps have these limitations, and so they will continue to be until the meteorological measurement system changes. Something that will not happen in the short term. That is why in recent years there is a very booming app: rain radar. Unlike traditional time apps, Rain Alarm is an app that is based on real -time radar data. These radar models do not work in the long term: they use data to make predictions in almost immediate ranges. This is why, with just opening the radar app, we can observe much more precisely the state of the atmosphere. Today, this is the most accurate way of knowing immediately how the weather will behave. And, still, it will still not be accurate. Image | ECMWF In Xataka | Aemet already knows when the storm that is soaking Spain is over. The problem is that another act comes another

Generating electricity using earth rotation seemed impossible. These physicists have shown that it is not

by

In July 2016, two American physicists, Christopher F. Chyba, from Princeton University, and Kevin P. Hand, from the NASA jet propulsion laboratory, published in Physical Review Apply A very exotic scientific article. In his text they defended the possibility of generating electricity taking advantage of The Earth Rotation Movement. His proposal required to build a device that was able to interact with The magnetic field of our planetbut at that time very few scientists took it seriously. Despite the bad initial reception that his job received, Chyba and Hand have spent the last nine years trying to build his electricity generation machine with the purpose of demonstrating that, indeed, his proposal works. However, during this period they have joined a third physique, Thomas H. Chyba, who investigates in Spectral Sensor Solutions, an Albuquerque company (New Mexico). It is dedicated, among other things, to develop electrooptic sensors to detect chemical, nuclear, biological and radiological threats. Chyba and Hand were right from the beginning On March 19, these three physicists published in Physical Review Research A new scientific article in which they experimentally demonstrate that, as suggested in their 2016 text, it is possible to generate electricity taking advantage of The rotation movement From Earth. To carry out their demonstration they have built the apparatus capable of interacting with The Earth’s magnetic field of which they talked in their 2016 article. Interestingly, this device is very broadly speaking a manganese and zinc ferrite cylinder that behaves like a magnetic shield. The experiment of these three physicists has shown that 18 electricity microvolts were being generated through the cylinder Once they had it ready, they guided him in a north-south direction with an angle of 57 degrees with the purpose of being perpendicular to both to the Earth Rotation Movement as to its magnetic field. And then they placed electrodes at each end of the cylinder to be able to measure the voltage of the electric current that they expected to be generated. And they succeeded. His experiment showed that they were being generated 18 electricity microvolts through the cylinder without any other energy source. According to these physicists, the only plausible possibility is that, as they expected, the land rotation movement is responsible for the generation of this small amount of electricity. When Chyba and Hand proposed their idea in 2016, other scientists criticized it by arguing that any voltage caused by a device similar to that they have finally built would be canceled at the time when electrons were repositioned during the generation of an electric field. But your experiment shows that it is possible to capture that voltage. An 18 microvolt voltage is insignificant in practice. It’s true. However, this is not important; The relevant thing is that, apparently, the proposal of these three physicists works. In fact, your plan goes through climb this technology To generate much more electricity, enough at least to be useful. In any case, there is something important that we should not overlook: its experiment still has to be replicated by other scientists and in other test scenarios to verify that this voltage has not really been generated by any other external source that, perhaps, the protagonists of this article have not taken into account.

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

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.
