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.

Embute a V8 to a Toyota IQ. And you can buy it

by

Intelligence quotient. A classification that helps establish whether you are inside or not (for better or worse) of the average of the rest of the population in terms of your cognitive performance. Or, in flat words: intelligence. IQ exams are used to establish whether people have any cognitive problems or, for example, if you are well above the average. For the latter, the acronym IQ are usually related to the level of intelligence. That relationship was used by Toyota when presenting one of its urban cars. When presenting the Toyota IQ, the Japanese wanted to make clear one thing: it was an intelligent option. An urban car, of very restrained size and spent little to be used in the city. The association was as clear as Smart (intelligent and elegant in English) to a company that presented a car with very similar features. In Km77 They explained in their Toyota IQ test that it was a relatively spacious car for passengers and that, above all, it moved very well in city, with a very content radius but that, at the same time, its capabilities were not excessively sacrificed when it went on open road. Was, in summary, a Extremely intelligent decision for those who will look for a car in a city that would not spend much and who did not want to spend much more than 10,000 euros. All that intelligence that was diluted when a luxury brand was able to ask for almost 40,000 euros for that same car. Elon Musk vs Jeff Bezos: The Galaxies War One of the most rare astron Martin in history Because that’s what Aston Martin did with Cygnet. The English company took advantage of a collaboration with Toyota to give the IQ some touch -ups and put it on the market at a price of 40,000 euros. The idea of ​​the company was clear: enjoy a Aston Martin in your day to day without the need to get into the street The typical DB9 that you keep in the garage. It was something like a tuned Toyota. The front hood received two air inputs or the front grill took the image of the English company. Aston Martin barely tried to hide that in front of us we had a Toyota IQ But there was a problem: it was the same car. Literally, Aston Martin Cygnet and Toyota IQ was the same car. Aston Martin did not even bother to put a much more powerful engine to attract potential customers and, at least, make you believe you were before the sports version of the Japanese model. They lost the opportunity to make him something anthological, one of those small sportsmen who go down in history. Something that broke everything reasonable. Use the 1.3 VVT-I 98 CV It was also available at the Toyota was to kill the potential of the car. A decision that came because of the imperative need to have to reduce the company’s average emissions and thus avoid fines. That ballast became evident with its sales. Especially if we take into account that the Cygnet could add a few thousand to the final invoice if it was chosen with automatic change (1,435 euros) or leather upholstery (another 3,988 euros). Although the owner of a Aston Martin did not have many problems to leave 40,000 euros in a utility … it was difficult to think that they were going to sell it simply by changing the grill. To have an idea of ​​its commercial failure, the company planned to sell about 4,000 units a year of the Cygnet. Sold at a rhythm of 150 units annually. The failure was such that it squandered the little economic effort that the company had made and killed the possibility of entering a new market if it had offered an attractive product. But there was a very special Aston Cygnet In spite of everything, we can forget some of the things I wrote above. Because, indeed, there was a really special Aston Cygnet they called Aston Martin V8 Super Cygnet. The English company struck a tremendous V8 in one of the units manufactured and created the ONE OFF That every lover of tiny sportsmen would like to have seen in series. The car appeared for the first time in Goodwood in 2018 And, this time, I did have a body at height. It seems that the Toyota IQ had been atibored to steroids, with widened wheel steps of carbon fiber, the new company of the company (more gross and less elegant), specific disc brakes for this unit, anti -collide cage with competition recharging seats, new transmission tunnel … an engineering exercise that was resolved with the jewel of the crown. That jewel was a huge ATMOSPHERIC V8 LITER MOTOR that delivered a power of 436 hp (inherited directly from the Aston Martin Vantage S) that launched the cygnet to the 100 km/h in 4.2 seconds. It should be a feeling to reach 272 km/h that marked peak speed in a chassis that measured less than three meters. And now, that ONE OFF It is for sale. Specifically in the portal of Nicholas Meeknown for the spectacular models that you have available among your offer. At the moment, who looks for a Aston Martin Cygnet will find them around 40,000 euros but, obviously, this unit should be much more expensive. In the purchase portal they have not published its price but it is expected that it reaches an extraordinarily high figure since the base model has already sold very few units and this version with V8 motor is what every fan would have asked when we knew that Aston Martin would have his own urban model.

If the question is how much money it exists in the world per person, this graphic developer has the answer

by

Imagine there was a form of distribute all money in cash of the world equitably between Each inhabitant of the planet. Thus, a Wisconsin farmer would have the same cash That a potter in New Delhi, a goat shepherd in Namibia or a dentist in Sydney. How much money You think it would correspond to each inhabitant? The short answer: everyone could Buy a Sandero Dacia. The world money supply is not the same as world wealth The modern economic system encompasses many financial and monetary elements that define the term of wealth. So one of the ways in which the exercise of imagination distribution of wealth that would allow mitigating world poverty can be distribute all money in cash that exists in monetary markets around the world. This “cash” money is known as M2 Prenss supply And it is an intermediate monetary aggregate that includes money in circulation from around the world and certain bank deposits with high liquidity and with a period of up to 2 years, savings and money market accounts, as well as deposits with availability with notice of up to three months. In other words, the monetary supply M2 is all that money you could have in your pocket in a relatively immediate way. The concept of monetary supply m2 differs from the Global wealth or heritage in which this includes assets and real estate properties or mercantile that, although they can have a lot of value, are not easily redeemable for Count and sound money. According to data collected by CEICM2’s money supply amounts to 123.3 billion (Europeans) of dollars In 2024. That is, joining all the effective of all the economies of the world, we would add that money. According to the report ‘Global Wealth Report 2024‘Prepared by UBS, the world’s private net richness in 2024 was encrypted in 487.9 billion dollars in total. To help us see that information in a more graphic way, in Visualcapitalist have created an infographic in which the M2 MONITORY OFFER DATA obtained by CEIC, and divides between the world population data registered by the United Nations Department of Economic and Social Affairs. Distributing all world cash As we said, the world M2 money supply registered by the CEIC economic body in 2024 is 123,313 billion dollars (with the Anglo -Saxon system they would be trillion), while the data of the world population in 2024 reveal that we are currently 8,161,973,000 inhabitants In this little blue marble that we call planet Earth. The result of the equitable cast is that, each inhabitant of the planet would correspond 15,108 dollars Or, what is the same, about 13,944.28 euros to change. According to the Virtualcapitalist calculationsthat would be equivalent to the expenditure generated by the list of the purchase of an average home for two years, a second -hand car, or also reaches to buy a Sandero dacia. Without extras, yes. Spain is better for accounts If we repeat the same exercise, but circumscribing the data to the scope of Spain, the amount that each Spaniard would receive would be somewhat higher. According to CEIC’s records for Spain in December 2024the supply of monetary m2 available was 1,647,611,114 million dollars (or 1,648 billion dollars). On the other hand, the data of INE population count January 2025 left a total of 49,077,984 inhabitants in Spain. That lets us, by distributing the total of the money supply among the inhabitants of Spain, each would receive 33,571.29 dollars or some 30,967.97 euros to change.

The first person who made a crucial demonstration in nuclear physics was a Chinese woman from the 50s

by

In the 50s of the last century China was a very different country from the current one. He Chinese Communist Party Led by Mao Zedong he had defeated the nationalists who made up the Kuomintang After almost three decades of armed conflict. Imperial power He had disappeared and the country had embarked on very deep structural changes that culminated in the birth of the People’s Republic of China in 1949. The members of the Kuomintang retired to Taiwan that same year and left the land clear to the complex social, political and economic transformation that Mao Zedong had already pergeated. The new regime had erected on communist principles with the purpose of leaving behind many centuries of a feudal organization that had drastically limited the country’s development capacity. The problem was that their foundational tools were A strong ideological control and an aggressive political repression that did not admit any kind of opposition. So China was an eminently agricultural country that desired to modernize and go The same path of industrialization in which they had many decades plunged other nations, such as the United Kingdom, the USA, France, Belgium or Germany. The Mao government launched a very ambitious agrarian reform that pursued agricultural production and increase its efficiency. In this context, scientific development was an important part of its progressive strategy, but was subordinated to the ideological and political principles of the communist regime. This was not at all the ideal culture broth to flourish a young China passionate about science. And much less for nuclear physics. But he did. Chien-Shiung Wu had everything against him At the beginning of the 20th century, most women in China did not have the slightest opportunity to study. But Chien-Shiung Wu was special. He was born in 1912 in the province of Jiangsu, and when he was barely five or six years old, his parents realized that she was a very intelligent girl who was endowed with a curiosity and improper cunning of such a young person. Fortunately for her, her parents appreciated the value of education despite how difficult it was to a relatively humble family to access it. Wu was given mathematics and physics. He highlighted so much from his youth in these scientific disciplines that he managed to access higher physics studies in The prestigious Central National University (It is currently known as Nankín University). It is important that we do not overlook that at the beginning of the 30s of the 30s of the last century China was, as we have seen, a fundamentally agricultural country that was mired in the revolutionary seizure triggered by the disappearance of imperial power. In this social and political context it was very difficult for a woman to get access to university studies. And it was even more unlikely to stand out in a scientific career. But Chien-Shiung Wu did it. He graduated in Physics in 1934, and two years later he decided to travel to the US to complete his training. His extraordinary academic curriculum helped him be admitted at the University of California in Berkeley under the supervision of Ernest Lawrence, The inventor of the cyclotronand in 1940 he obtained his doctorate in Physics. From this moment on, a meteoric career began as a researcher specialized in gamma ray emission in particular, and in nuclear physics in general. Its domain of nuclear spectroscopy, a technique that serves to study the behavior of atomic nuclei observing the radiation they emit or absorbwas the presentation card that caused it to be signed by the Radiation Laboratory of the University of California. And shortly after, already in the middle of World War II, he participated in the Manhattan project as part of the Delegation of the University of Columbia (New York). His extraordinary academic curriculum helped him be admitted at the University of California in Berkeley under the supervision of Ernest Lawrence, the inventor of the cyclotron A good part of her professional career ran in this last institution as a researcher and starting professor, and during her early years at Columbia University was highly appreciated by other teachers and physics students for which she was her greatest contribution to the Manhattan project: The development of separation technology of uranium isotopes. However, their achievements had just begun. And it is that the work for which it has definitely gone into the history of physics came, as we have advanced in the head of this article, during the 50s. Wu has gone down in his experiments in nuclear physics In 1956 Chien-Shiung Wu designed a very ingenious experiment using cobalt-60 cooled to an extremely low temperature. Its purpose was to study whether electrons emitted in the presence of a magnetic field of great intensity are distributed asymmetrically, as theoretical physicists had hypothesized Tsung-Dao Lee and Chen Ning Yang, with which it collaborated. His experiment worked correctly, allowing WU to demonstrate that the emitted electrons During the disintegration process They were preferably dismissed in one direction. And not in a symmetrical way, as physicists believed so far. Wu’s experiment played a crucial role in the concession in 1957 of the Nobel Prize in Physics to the Tsung-Dao Lee and Chen None theorists This test has gone into the history of science as “the experiment of rape of Wu’s parity.” Its importance lies in its ability to demonstrate that in weak nuclear interaction, which is the fundamental force responsible for some atomic processes, such as, for example, Beta disintegration, Symmetry is not fulfilled. If we express it in this way it may not seem important, but it is. It is very important knowledge. In fact, he not only supported the theory of Beta Disintegration of Enrico Fermi; Without him, physicists would not have been able to elaborate the theories that currently shape the Standard model of particle physics. Wu’s experiment played a crucial role in the concession in 1957 of the Nobel Prize in Physics to Lee and Yang. Many scientists consider that the right thing … Read more

Most likely you are drinking your coffee with bad milk. And the fault of everything has a factor: the temperature

by

There is a scene that you have surely lived if you have asked for a coffee in a restaurant or a cafeteria: you ask for a coffee with milk or a capuchino and, after assembling value, you ask that the milk is not very hot. That is when such a coffee serve you darkness And you hear the crackling of a milk that ceased to be a edible product to become a lava. And there is something important to take into account in all this: although the coffee they use is good -Not Torrefacto-, such hot milk is ruining the drink. Specialty coffee shops against lava. Prepare a coffee It is a very meticulous process. The problem is that the coffee culture of many sites is quite improvable, which has led us to think that the way of drinking any preparation that is not a single with ice must be an experience in which we have to spend ten minutes waiting for coffee to cool. The difference between a specialty cafeteria and any bar is not alone in coffee, but also in how they treat milk. And that is where the temperature comes into play. In specialty coffee shops, any coffee that carries milk will be rather temperate. You can even start taking it as soon as they serve you. This is not for Eviction the table as soon as possible and that the following client passes, but for something deeper and that has a scientific basis. 65 ° C.. That is the maximum temperature that the milk of a coffee with milk should have. Anyone between 55 and 65 degrees Celsius, happens to be more accurate, and maintaining it is crucial to protect something fundamental in milk: its proteins. When we heat the milk with the foamer, if we stay in that temperature range, their proteins experience something called ‘denaturation’. This means that milk proteins lose their structure and form spheres around the air bubbles that are produced when milk subjected to the sparkling. That process, together with the interaction between the casein and the fat of the milk, serves to stabilize the foam, making it more creamy. The sweetness of the liquid is also enhanced without falling into the burned of it because the natural sugars of milk break down just as not to pass. And? If we pass temperature, the balance between fats and proteins is broken, so the foam will be more airy and lose that softness and creaminess, making the drink less dense. But apart from the aesthetic function (because the art is worse with milk that exceeds 65 degrees) and the alteration of the texture of the drink, there is another issue that we must take into account. When we exceed the temperature, the proteins are excessively denatured, which leads to the excess of air bubbles that we have already commented, but also to the presence of a flavor that can be unpleasant because the sugars are passed and the fats are oxidized. In addition, the texture will not be so velvety and we will not only have a much flatter drink in flavor, also in terms of density. Template, better. And it happened to me. Going to a specialty cafeteria for the first time and finding a tempered capuchino was a surprise, but beyond the initial by temperature, the next was that there were fruity notes of the coffee I could appreciate. Preparing the same type of coffee in my house, with a foamer who later saw that it exceeds that temperature, all those notes, simply vanished. My mistake during all that time? Do not pay attention to temperature. And that temperature is one of the many reasons why drinking coffee with milk in many countries, and out of specialty coffee shops, is a battle. Preparing good coffee is very complicated, so much that there are those who study What are the best reactions and temperatures To, among many other issues, heat the right the milk to change the texture of the drink without affecting its flavor too much. Ojito with reuse. On the other hand, and I recognize that it has also happened to me, we cannot reuse the milk that we have already subjected to this process in the foamer. The scene may sound to you: it is one of the first times you make coffee with your new coffee maker and you throw more milk in the jar. That goes up as it is foam, so we have half left and we decided to take a glass jar, let it temper and store it in the refrigerator to use it in another coffee. We spread it again and … there is the error. It’s something James Hoffman –Barista and coffee disseminator- already explained A few years ago: when we heated milk for the second time, we are exaggerating the denaturation of proteins and promoting oxidation of fats, which generates a more stale flavor and an unpleasant texture. Therefore, if you want to prepare a better Latte At home, it is best to have a steel jar that allows us to feel the ideal temperature and, until we have trained the sense of touch to identify what that temperature is, something like a cheap kitchen thermometer will serve as a guide. Everything is to stop drinking milk in poor condition with each homemade cap … Image | Chris Reyem In Xataka | The first step to improve coffee you drink is to grind it yourself.

What cars can circulate and which ones rest on March 8

by

As every week, with you, today does not circulate sabbatino. The fact that? Indeed, the most problematic day of today does not circulate, the project designed by the CDMX Ministry of Environment (Sedema) to reduce pollutant emissions that are present in the atmosphere and, therefore, we breathe. Although we do want to put a little less drama, we will say that the Today does not circulate It simply tries that drivers leave our cars at home. Because, otherwise, we will be facing a fine. A fine that, of course, will only be imposed if we fail to comply with the rules where the program is active. And where is it active? In the 16 mayors in Mexico City and in the following conurbation municipalities of the State of Mexico: Atizapán de Zaragoza Coacalco de Berriozábal Cuautitlán Cuautitlán Izcalli Chalco Chicoloapan Chimalhuacán Ecatepec de Morelos Huixquilucan Ixtapaluca La Paz Naucalpan de Juárez Nezahualcóyotl Nicolás Romero Tecámac Tlalnepantla de Baz Tultitlán Chalco Valley What cars and plaques affect the Sabatino today But what do we have to know to correctly understand today? The first thing to set is in the upper image. As you can see, it specifies the restrictions that apply every day. But if you realize, on Saturdays they are special. From Monday to Friday, the standards apply taking into account the hologram and plate number and it is clear who should stay at home. But on Saturdays we can find the following situations: Cars that can circulate every Saturday Cars that have to rest every Saturday Cars that rest on a Saturday yes and another Restrictions, yes, do not apply all day. They are active between 05:00 and 10:00 p.m.. That is, at night we can move freely and without taking into account any type of restriction. So how does Sabatino apply today? Well, drivers will have some things into account on Saturdays because, as we said, they are special days. Thus, the following cases can be given. Those who have hologram 0 and 00. In that case, you can rest because you have no problem. You can get rid of any Saturday from circulatory restrictions and, therefore, you can move with total freedom. We have worse news if you have a hologram 2. In this case, Tamppoco looks at the plate number because you will have to leave the car at home yes or yes. Every Saturday, cars with hologram 2 must stay out of circulation because the most polluting cars are considered. Finally, we have cars with hologram 1. In this case, we do have to look at the plate numbers. In this case, the March 8 We are on the second Saturday of March. And, therefore, it is cars with hologram 1 and plaque finished in number that rest. Because? Because the pairs rest the hologram 1 with plaque finished in torque. And the odd weeks (the first and third, for example) will have to rest the hologram 1 cars with an odd number. In this way, the rotation is ensured week by week. Of course, we cannot forget that there are some exceptions that go beyond being able to circulate freely at night. Thus, the following cars can move with total freedom: Those that work for electricity, natural gas or are hybrid Those who have disabled plate All those dedicated to urban transport services (includes funerals) Those who offer school or passenger transport Those destined for public safety and/or civil protection In case of breaching these restrictions, the fine will be 20 to 30 times the unit of measurement and update (Uma), which is equivalent to 1,924.40 pesos and even 2,886.60 pesos.

The European Central Bank has been fighting for five years to literally create a “European Bizum”. Now has taken a key step

by

Europe wants to have its own instant payments system. That would allow the dependence of the great market leaders, Visa and Mastercard, and strengthened the European financial ecosystem. And the plan begins to take shape with Bizum as a great protagonist. Bizum is looking for allies. As they point out In Electomistthe idea is to unify the payment systems that are currently working in the various countries of the European Union. Bizum, protagonist in Spain, has its twin schemes with Bancomat Pay in Italy and Sibs in Portugal. All of them now pose to be interconnected with a specially relevant reference. Wero, the German Bizum. The Instant Payment System It has been since summer 2024 being the great alternative in France (where they used Paylib), Germany (Giropay), Belgium and Luxembourg (Payconiq) and Holland (ideal). This project of the European Payments Initiative (EPI) is taking shape, and it can precisely be the other great component of that fusion of instant payment systems in Europe. The ECB wants a European bizum. Sources close to negotiations indicate that the project is on the table. To get ahead, we would have that giant of the instant payments that for years has tried to boost the European Central Bank (ECB). A long -sought project. Five years ago the European Commission He started looking that “European bizum” with the launch of the aforementioned EPI. In the project 16 great banks of Spain, Germany, France, Belgium and the Netherlands participated. A year later the figure amounted to 31 entities. The objective, offer a unified payment solution with a payment card and a digital purse. But that has gone through problems. The initiative was promising, but the slowness of its implementation and the excessive budget necessary to achieve this caused several banks to withdraw from the project. As indicated in the economist, the Spanish bank had to contribute 300 million to the initiative, something debatable if we consider that Bizum has existed since 2015 and has a massive acceptance. Spain, Portugal and Italy teach the way. Last year Bizum, Sibs and Bancomat Pay began working on connecting their platforms and making possible instant payments between these countries in the same conditions as to the national scale. It was also the result of the Bizum Union to the European Association of Mobile Payment Systems (EMPSA), which was the consortium of southern Europe. That alliance brings together 43 million users, of which 28 belong to the Spanish system. Germany, France and Belgium were looking for something similar. Something similar happened with the EPI and Wero, which interconnected the mobile payment systems of Germany, France or Belgium and wanted to become the European Payment System. Now both consortiums have approached positions and according to the sources mentioned there are options to end working on an interconnection of all systems. This looks good. It is not clear if the conversations will end with a single European system – will Bizum be called? Wero? – Or if at the moment we will work on that interconnection of all these applications separately, but of course these efforts can be the principle of something great and important for the European panorama of instant payments. It is already known. Union is strength. In Xataka | The arrival of the digital euro is inevitable: let’s say goodbye to anonymity

The Dana left 800,000 tons of waste and mud in Valencia. Now they will reuse for raw material

by

The Dana that hit the Valencian Community on October 29, 2024 caused great shock throughout the country, leaving more than 200 fatal victims. In almost five months, I They have generated More than 800,000 tons of waste mixed with mud, a huge figure, since the Valencian Community usually produces an annual average of 180,000 tons. And what are they going to do? In recent months we have seen with much of the national population has turned with the reconstruction and aid in the streets of the Valencian municipalities. However, given the data on the waste, the Ministry of Environment, Infrastructure and Territory He has decided to reuse The land mixed with flood waste for various works in landfills, quarries, agriculture and construction. Reuse. One of the points enabled to carry out this work is in one of the most affected areas of the catastrophe, Catarroja. The project consists of a machine that will make a screening between earth and waste, and then analyze them and make sure they are free of pollutants. Once treated, the Earth can be reused in different spaces. However, it is not there, because it is diversifying in other types of waste, such as tires, butane, scrap and mattresses, for its specific treatment. Reuse in agriculture. The floods caused by the overflow of rivers and ravines dragged large amounts of mud, debris and waste that affected both crops and soil quality. La Ribera Alta and the area of ​​L’Abufera, Key areas for agricultureThey saw how their rice crops, citrus and vegetables were destroyed. For this reason, working on the recovery of the affected soils trying to the sludge and the polluting sediments. However, mud samples taken in the area of ​​the Natural Park of L’Albufera are currently low, but concern persists on long -term effects. Other points to manage waste. The Ministry of Environment, Infrastructure and Territory has created Local collection points in which to accumulate the remains of the municipalities. Transfer points have also been enabled where to make a first crushing treatment, separation of metals and mattresses, located in Quart-Manises, Picasent, Catarroja and Alfafar. Waste energy management. While the Valencian Ministry has promoted this type of solutions, also It is exploring The possibility of incinerating some of this waste. In fact, incineration, as if it were a thermal power plant, allows transforming the heat generated into electricity. In fact, several experts They have defended That incineration reduces the percentage of rejection and, in addition, put as an example that burned waste produces ashes that are useful to develop, among other things, cement. In addition, Spain has advanced Significantly in the use of the biomethane, a clean energy source that can be generated from organic waste and landfills. The use of biomethane could complement the efforts of the Ministry of Environment, Infrastructure and Territory, by providing a sustainable energy solution and reducing the environmental impact of the waste generated by the DANA. Forecasts While the terrain is still being cleaned, one of the areas most affected by waste dragged by the Dana has been the Albufera of Valencia and its beaches. In them, more than 60,000 kilograms of garbage have been removed, including up to 36 varieties of different waste, such as tires, bumpers, butane, furniture and plastics. As cleaning and recovery efforts continue, more additional measures will have to be implemented to address waste dragged by future floods or natural catastrophes.

A Japanese restaurant has brought its obsession with fresh fish to the extreme: it allows you to fish yourself

Visiting Japan is immersing yourself in a country where the traditional and modern coexist in harmony. Its big cities combine futuristic skyscrapers and streets full of neon lights with millenary temples that have resisted the passage of time. In any walk through its streets, it is inevitable to find restaurants where fish is the absolute protagonist. And it’s no accident: in Japan, Fish has been a pillar of its gastronomy for centuries. Here, the menu is not requested, fishing. If you think you’ve seen everything about freshness, Japan always has more to offer. There are restaurants where chefs personally select the best fish on the market every day, but what if instead of waiting for them to serve you, is you who fish it? In Osaka, about five hours from the center of Tokyo, there is a place where the menu is not chosen, it is captured at the time. Our protagonist bears the name of “ジャンボ釣船つり吉”, which could be translated into Spanish as “Great Tsurikichi fishing ship.” As we can see in Google Maps screen capture, it is far from the bustle of the great avenues of the Asian city, and is immediately distinguished by its facade decorated with a fishing boat and posters with large Japanese characters that tell us what we will find inside. As explained on your websitewhen crossing the restaurant door the first thing will be to check the letter and choose the fish we want. Once decided, the staff will give us the right equipment, be it a fishing cane or a salabre, and will guide us to the fishing area. In that pond, where fish swim outside of their destiny, true experience begins. They assure that it is an apt challenge for all ages. After fishing, it is time to enjoy food in one of the four rooms available. We can choose between Tatami type seats in a ship -shaped area or, if we prefer something more conventional, tables with western -style chairs. Now, suppose we are ready to live this experience. How much will it cost us? It is time to take a look at the letter and calculate the budget. How much does this experience cost? When planning the expense, the first thing we should consider is that the price is based on the entire fish that we catch. Thus, a red kissing costs 3,124 yen (about 19.50 euros), a sole has a price of 2,840 yen (approximately 18 euros) and a listing juris rises to 4,980 yen (around 31 euros). Once the piece fish, we must choose how we want to prepare it to us, which is an additional cost. For example, a frying with Ponzu adds 300 yen (about 1.90 euros) to the final price. In addition, if we want to accompany our dish with seafood, we must take into account that they do not have a fixed price. In this case, the staff will weigh and inform us of the cost before preparing them. Marketing, Tourism and Gastronomy. It is no secret that Japanese gastronomy is rich and diverse, with fish and rice as fundamental pillars for centuries. However, many of the dishes that we consider today representative of Japan, and that have crossed borders, are not the result of a centenary tradition, but of relatively recent adaptations. Without going any further, until the 1990s, no one in Japan ate sushi with raw salmon. It was a marketing campaign that made it a standard, more than an entrenched custom. But tourists continue to come in mass in Japan in search of a unique experience. And there is no doubt that the country has much to offer, especially in the gastronomic field. However, not everything is good news, neither for the premises nor for those who visit it. An ingredient as essential as rice suffered a remarkable crisis: in full tourist boom, The shortage shot prices and led some restaurants to pay anything to stock up. When what matters is the show. Eating typical dishes in Japan has its charm, but restaurants have found ways to go further, especially when the goal is to attract tourists willing to spend on experiences. The possibility of fishing your own food in a place set as a ship is not only a gastronomic option, but a claim designed to turn dinner into a show that seduces both visitors and premises. {“Videid”: “X8D7XNV”, “Autoplay”: False, “Title”: “Tricks to travel cheaper- Drinking tea is something that can be done anywhere in the world, But attending a tea ceremony is another story. In Japan, this ritual has become an attraction for tourists looking for more than a simple infusion. The experience is not limited to drinking tea, but extends for hours, with different varieties and meals included. Something that originally had a deep cultural significance is now also sold as an experience for the visitor wanting to spend. But the show does not end there. If tea is not enough, there are always more options to live Japan in a big way: geisha shows perfectly choreographed for the tourist, high exhibitions where tradition and show intermingle, and the Bunraku puppet theater, a cultural element that continues to find its place in a country where more and more things become attractions for the photo. A HAND FOR MOUNT FUJI. To promote other forms of tourism in Japan could be one of the keys to decongest Mount Fuji, a place that for centuries was a symbol of spirituality and personal improvement, but today dealt with massification and its consequences. What was previously an intimate journey has become a crowded tour of hikers, with tails on the top and an environment that is increasingly feeling the weight of uncontrolled tourism. In Xataka Japan has put a spicy in Spain in a peculiar way: with a "Madrid Osaka" In a town of 93 inhabitants To mitigate the impact, The government has begun to take action: daily visitor limits have been established and an online reservation system has been … Read more
