The extreme stress of the Spanish water network explained from within

by

The images have flooded social networks this weekend: the Aldeadávila dam “turbinating at full capacity” with the Duero river descending with enormous force, or the Iznájar reservoir recovering its splendor in a matter of days. They are hypnotic images that hide a much more tense and calculated reality. While the citizen sees natural spectacles, the engineers see a fight against the disaster. In the midst of this “festival” of storms that has shaken the peninsula this month of February, One phrase sums up the situation better than any other. It is pronounced by José María Sanz de Galdeanodirector of Hydrological Planning and Works of the Basque Water Agency (URA): “The dams were not designed for floods, but today they are key to cushioning them.” These infrastructures, designed decades ago so that water comes out when you turn on the tap or to turn on the light, have become—almost by historical accident—the last line of defense between the perfect storm and the safety of the populations downstream. A winter concentrated in a few days. To understand the magnitude of the event, we must first look at the Basque Country, where the orography and intense rains have tested the system. As explained by Sanz de Galdeano in the SER ChainEuskadi has faced a winter marked by episodes of very intense rain concentrated in very few days. The situation has forced the activation of the two major Basque regulatory systems. On the one hand, the Zadorra system composed of the Ullibarri-Gamboa reservoir and the Urrunaga dam. On the other hand, the Añarbe system is responsible for supplying the Donostialdea area. It is not a local phenomenon. It is a symptom of a broader hydrometeorological pattern that has affected the entire peninsula. While in the Tormes system, reservoirs like Santa Teresa are close to 80% and release water preventively to defend the city of SalamancaIn the south the situation has been even more drastic. In Andalusia, the Iznájar reservoir—the giant of the community— has doubled its reserves in just two weeks, going from a critical 25% to exceeding 50%, something that had not been seen in a decade. The intensity has been such that the AEMET even warned of scenarios of soil saturation with impacts “some of the highest in the world”, causing water to gush directly from the ground in places like Grazalema (Cádiz). forcing preventive evacuations. From supply to “lamination”. The relevant thing about these weeks is not only that it has rained, but how we have managed that rain. Sanz de Galdeano puts his finger on the sore: “These infrastructures were built primarily for water supply, not specifically to laminate avenues.” However, its immense storage capacity has made it possible to change its function on the fly. Dams have acted as giant shock absorbers. “They have sufficient volume to play with reserves, create space and retain water at the most critical moments,” says the director of URA. Sanz de Galdeano’s warning has scientific support. A study on the effectiveness of dams in the face of climate change confirms that infrastructure designed with “historical data” They are operating blind to the new reality. Old models did not account for this extreme variability; under severe warming scenarios, the risk of large dams overflowing could multiply by up to 17 compared to historical records. The conclusion is technical but terrifying: the effectiveness of a dam decreases dramatically under extreme hydrological regimes if adaptive management is not applied. This excess water has had an unexpected side effect on the energy market: Spain’s “battery” it’s so loaded (117% more stored hydroelectric energy than last year) that nuclear energy is no longer competitive. The Trillo plant, for example, has been disconnected from the grid because, given such an abundance of turbineable water, the numbers simply “did not add up.” Choreography of floodgates. The precision mathematics that decides how much water reaches your home. The management of these crises is a precision choreography that Sanz de Galdeano graphically defines as working “with one eye on the river and another on the sky.” The technical key lies in the “reservoir”: the empty space that is deliberately left in the reservoir before the rain arrives in order to swallow the flood. The director of URA details how it is applied this differently depending on the capacity of each system: In the Zadorra (High regulation): These dams control 60% of the upstream basin. This allows for drastic intervention. The figures from Sunday night are the best example: 260 cubic meters per second of furious water entered the system, but the floodgates only let out 54. That difference (more than 200 m³/s retained) is the flood that was avoided. In Añarbe (Less regulation): Here the dam only controls 23% of the basin. Most of the river water circulates freely, so there is less room for maneuver. Even so, the strategy is the same: when the river goes high, floodgates are closed to retain “as much as possible.” All this is done under administrative coordination complex but fluid between URA, the Ebro Hydrographic Confederation and that of the Cantabrian Sea. Not all barriers are the same. In this context of saving dams, a reasonable question arises: why then are some dams on Basque rivers being demolished? Sanz de Galdeano makes a crucial distinction between large regulatory infrastructures and small weirs. “These are not large infrastructures like those of Zadorra, but rather low-rise structures that have no real capacity to manage avenues,” he clarifies. The elimination of these small obstacles responds to two logics: Environmental: they allow fish and fauna to ascend the river, improving ecological health. Hydraulics: Although it may seem contradictory, these small walls can raise the water table in local floods, worsening the problem instead of solving it. However, large dams have their own silent enemy: sediment. Experts and organizations like Greenpeace warn that torrential rains They drag tons of mud that accumulate at the bottom of the reservoirs, subtracting their real capacity (that “hole” that Galdeano spoke of) and … Read more

In 1957 the BBC explained that Italians picked their spaghetti from “pasta trees.” And millions of Britons believed it

by

On April 1, 1976, Patrick Moore He entered the BBC Radio 2 morning show to comment on a curious astronomical phenomenon that was about to take place. He explained that, just at 9:47 that morning, Jupiter and Pluto would align with the Earth, producing a gravitational effect that would predictably be noticed throughout the planet. According to Moore, the most (re)known astronomer in England at the time, those who jumped at that precise moment would notice a brief but significant sensation of weightlessness. Just after 9:47 the BBC lines were jammed with people saying that, indeed, they had observed this decrease in gravity. The only problem is that it was all a joke. On April 1 (‘april fool’s day‘) is the Anglo-Saxon equivalent of our April Fool’s Day and Moore’s action was, indeed, an April Fool’s joke. A very successful prank: a woman even claimed that she and eleven other friends had been “dragged from their chairs and orbits gently around the room” as a result of the gravitational phenomenon. In 2008, the British network announced that a colony of flying penguins on King George Islandvery close to Antarctica. In fact, they made a video as you may have seen above. Another very funny one was the ’57 documentary about the “pasta trees” from which the Italians collected spaghetti. the dragons return The BBC has a long history of dabbling with pranks and science, but they’re not the only ones: to the now traditional BJM joke numberwe can add very funny jokes like NASA’s cow spacesuit, the Stonehege forgery by Martínez Ron or the one Nature published in 2015 about the existence of dragons. “Emerging evidence indicates that dragons can no longer be dismissed as creatures of legend and fantasy, and that anthropogenic effects on the global climate may be paving the way for the resurgence of these beasts,” they said in Nature. And, hey, it sounded like a great argument against climate change. In ’96, Discover Magazine published a long report about a new fundamental particle in physics, the bigon, and it was the size of a bowling ball. According to scientists, the only factor that prevents us from identifying them is that they only exist for a millionth of a second. The article ended on a wonderful note: “Is there any chance that bigon is just some kind of ridiculous April Fool’s Day joke, as almost every other physicist says? ‘People are so cynical,’ Zweistein replies. ‘Science,’ he notes, ‘routinely produces findings that seem too wonderful to be believed, and yet turn out to be true.’” But without a doubt my favorite joke was from CERN in 2015. That April 1st, they released a press release with a bang: they had found the “first unequivocal evidence of the Force.” Finally, so many millions invested were useful for something! As the researchers explained, many details were unclear and much remained to be investigated, but the preliminary results They indicated that this new physical phenomenon could be used for “long-distance communications, influencing minds, and lifting heavy things out of reservoirs.” The research was carried out by a research team led by the prestigious Professor Ben Kenobi from Mos Eisley University on Tatooine. So that later they say that scientists are not doing well.

The most expensive cities in the world to live in 2025, explained in a very illustrative graphics

by

In 2025, the cost of living in some cities is a combination of high prices in goods, services and housing, which can only face who have income enough for it. For those who do not reach enough income to cover those basic needs that each city demands are dedicated to poverty or to move to other cities More affordable, something that is already beginning to happen in our country in large cities such as Madrid or Barcelona. The “Numbeo Index” Numouso is a database Collaborative that collects the prices of restaurants, services and goods in the main cities of the world and, based on this data, it produces listings in which you can analyze which cities are the highest cost of life, in which the price of housing has a greater impact or determining the economic effort of its inhabitants to live in them. For establishing a reference point in the comparison, Numbeo uses New York data as a reference value 100 in all its data. That implies that, if another city has an index of 112 in one of its parameters, it means that, in that parameter, that city is 12% more expensive than New York. If the value of the index is 88, it implies that it is a cheaper 12%. Based on these data, the portal Visualcapitalist.com has elaborated a graph in which it is clearly represented in what cities in the world is more expensive to live. The most expensive cities to live The graph prepared by VisualcapitalistNew York leads the global ranking as the most expensive city in the world. According to data collected by Numbeo, New York is positioned as the most expensive city, with a fork in the rent price ranging from $ 1,100 to $ 4,108 for an apartment in a room and up to $ 8,174 for a three bedroom apartment. The Swiss cities of Zurich and Geneva are followed in the ranking, with an index of the Cost of life more rental of 93.2 and 90.6 respectively, indicating that living in them is around 7 and 10% cheaper than doing so In New York. In the fourth position there is San Francisco (85.3) that sneaks between the Swiss cities of Basel (83.9) and Lausana (83,4). If we focus on more expensive cities to live From Spain including the cost of life, we find Barcelona in position 137 with an index of cost of life including rental of 48.29, followed by Madrid (47.38) that occupies the 142nd position of the global ranking. Palma de Mallorca (43,79) and Malaga (39,24) follow them closely, occupying positions 180 and 203 of the world respectively. The weight of rent when living in a city The price of housing is a determining factor when establishing the cost of living in a city. For this reason, the list changes completely when the data is filtered to unlink the cost of the home of the equation. In that scenario, New York no longer leads the List of more expensive cities to livebut goes down to seventh place. Those who do maintain consistency are the Swiss cities, which remain the most expensive in the world to live, with Zurich (112.54) leading the list, followed by Geneva (111,41), Basel (110,71), Lausana (110.55) and Lugano (108,38). From the Spanish perspective, all cities fall several positions indicating the impact of the rental price at your cost of life. Barcelona (with a cost of life without rent of 57.03) goes on to position 183, while Madrid (55.79) falls less positions until 187. In the case of Palma de Mallorca (55,13) and Malaga (48,02) the fall is just ten positions, indicating that the housing price impact It is less than in Madrid and Barcelona, ​​but the cost of the rest of the index factors (food price, Public Transportation Pricerestaurants, services, etc.) It is higher in these cities. Living in some cities is more difficult A very important fact that can be extracted from this database on the cost of life in large cities, is the purchasing power index, which uses the salary average of that city and compares it to the base reference that is that of New York. The result leaves us a photo of which citizens do a minor economic effort to live In a certain city. In this scenario, the inhabitants of Mannheim in Germany are the ones who must make less effort to live in the city with an index of 198.64, which implies that these citizens can buy 98.64% more goods and services than a New York with their salary. The Swiss Basel (194,85), Bern (186.76) and Lausana (180,45) sneak into the top five, occupying positions two, four and five respectively. Only truncated Swiss hegemony the city of Erlangen (189,69) in Germany, which is placed in third position. Spanish cities draw a slightly different panorama, being Valencia (131,73) Alicante (113,27), Seville (102.62) and Madrid (101,39) the only ones in which its inhabitants They have greater purchasing power than a New Yorker in the field of his city. On the other hand, Barcelona (88,37), Málaga (86,34), Palma de Mallorca (86,34) are cities where the opposite happens, its inhabitants have a lower local purchasing power rate by having a lower average salary and a higher life cost.

Starship ended as an orange after flight 10. Spacex has not explained the reason, but the Internet has its theories

by

Starship’s tenth test has been a resounding success. The highest rocket in history took up a lot of expectation after three failed pitches, but this time one by one fulfilled the objectives of the mission. What surprised many was the orange color that the ship had when it merited in the Indian Ocean, a tone that we had not seen so far. Extreme suffering. After displaying Starlink Satellites simulators for the first time, Starship 37 lit an engine in the exorbitant space. It was then that Spacex tested the structure of the ship. An especially hard reentry angle, a series of aggressive maneuvers with the ailerons and a deliberately incomplete thermal shield made the ship suffer, but never disintegrated or stop maneuvering. Unlike flights 7, 8 and 9, which did not have a controlled reentry, flight 10 has allowed Spacex to collect an incalculable amount of data to improve Starship’s most critical and green part: Your reusable thermal shield. And it is precisely the thermal shield in the rocket belly that seems to have acquired an orange color after 26,000 km/ha 12 km/h. But how did that rusty tone occur if the thermal tiles are ceramic? A buoy and a mystery. Although Spacex has not yet pronounced on the subject, the images of the Ship 37 issued live from a buoy in the Indian Ocean called the attention of fans and aerospace experts equally. While the ship’s belly seems to have churruscado, the main theories do not point to The tiles fall Or they were burned, but for something deposited on them. The location of the experimental metal tiles at the vertex of the orange cone A refrigerant leak. The hypothesis that has gained the most force is the one that points to one of the key experiments of this flight: a metal tile with active cooling In the upper part of the thermal shield. Unlike the usual ceramic tiles, which are passive insulators, this experimental piece leaves circular cohete refrigerant to dissipate heat. The theory, supported by Analysts like Scott Manleysuggests that the tile with active cooling could have suffered a leak. The refrigerant fluid (perhaps methane of the rocket itself), by escaping and coming into contact with the incandescent plasma of the reentry, would have been burned and deposited throughout the fuselage, creating that characteristic feature of orange -shaped cone color that is appreciated in the images. In fact, the location of the experimental tile It coincides perfectly with the vertex of the orange area. Other possibilities. A non -exclusive theory is that experimental metal tiles (there were others on board without active refrigeration) They will simply oxidize Due to the extreme temperatures of the reentry, leaving that trail of oxide color. What seems clear is that we are not seeing the result of a ablation. Starship silica tiles are reusable insulating, not ablative shields that disintegrate by design. If the tiles had worn up to the point of exposing the ablative material underneath, we would be talking about a catastrophic failure of the system. A torture laboratory. This visual result, far from being a failure, is the direct consequence of Spacex experiments for this flight. The Starship 37 has gone through an authentic test bench for the thermal shield, which Elon Musk himself has pointed out as The main technological stumbling block of the program. On this flight, Spacex withdrew tens of tiles in key areas to see how the lower structure endured. At the same time, he added metal tiles and with active cooling to look for more resistant alternatives in areas of maximum thermal stress. And softened the edges of some tiles to mitigate the hot points observed in previous flights. In summary, the orange color of the Starship does not seem to be a sign of a catastrophic failure, but the visible footprint of an experiment taken to the limit.

In Spain there is a “black triangle” of fires between Ourense, Zamora and León. And it is not explained only by heat

by

The drawing is bleak. If you open Google Mapsactivate the “fire” function And you take a look at the map of Spain you will see that much of the flames that are devouring the mountain of the country (and some populated areas) seem to concentrate on a particular ‘triangle of fire’ between the provinces of Ourense, León and Zamora. There are the fires of Mozyuelas de la Caballea, Yeres or that of Queixa Chandrexawhich have already razed thousands and thousands of hectares. It is not the only region of Spain punished by the flames, but the big question is … Why do forest fires seem to be primed right in that region? The Spain that burns. It is not being a good August for the mountains of the country. According to The last report of the Ministry of Environment (Miteco), still incomplete because its technicians do not have the data of the large active fires, so far this year the flames have devastated 138,800 ha. And that is the calculation to August 10, so it does not include the devastated surface during the last week. To better understand what this data is, remembering that between January and the first week of September 2024 the forest fires burned 43,655 ha or that throughout 2023 they had calcined 89,000. If we look back, at the last decade, there was only one more disastrous exercise than the current one: 2022, when at this point of the year they had burned Around 215,000 hectares. Is the whole country the same? No. The flames have punished to a greater or lesser extent Andalusia, Estremadura, Castilla-La Mancha, Catalonia and the regions of Valencia and Madridto quote only some examples, but there is a specific area of the Peninsula that is suffering from the dentelladas of the fire with special virulence: the triangle formed by the provinces of Ourense, León and Zamora. Tan a Fast look To Google Maps to check it. There is Chandrexa de Queixa, which has affected more than 17,000 ha And it is already considered The most destructive of the history of Galicia. Also that of Mozyuelas de la Carballedathat passed from Zamora to León and has calcined several dozens of hectares. Looking for the causes. The big question is … why do that region hit so much fury? What are the causes? The question is interesting because it is not an isolated phenomenon: there are populations, like Castromil’sbetween Ourense and Zamora, who have resigned themselves to deal with fire every year. For the impact of the flames on the ‘triangle’ between Zamora, León and Ourense He wondered Recently in X Francisco M. Azcárate, professor of ecology, biology and environmental sciences. And its entry response is interesting: the succession of forest fires in that region of the Peninsula cannot be attributed to pyologists or negligence. Or that is not the only cause at least. In the background there are more complex structural reasons that have to do with the characteristics of that area or changes in the use of the territory. Meteorology earrings. “Climatically, the area fits perfectly with ecosystems that, naturally, have a high frequency of important fires,” Azcárate starts Before aiming the influence of the rainy season, during which biomass accumulates, and dry, marked by the mass of dry and very flammable vegetation. To this factor is added the frequency of fires in humid Mediterranean climates or the effect of climate change, which influences extreme temperatures and “extends the risk season.” The fire wave has in fact coincided with Another heat which began in early August and that already stands out as one of The most durable Since at least the 70s, which is when the historical Aemet starts. Although it is not an inflexible guideline, experts have not been warning that the fight against forest fires is especially complex when the known as the known as ‘Rule 30-30-30’: Temperatures above 30ºC, wind gusts of more than 30 km/Hy a humidity of less than 30%. Click on the image to go to Tweet. The perfect cocktail. Not only do climatic conditions or heat wave influence, which has spread far beyond the Ourean-Leon-Zamora triangle. Another of the keys that explains the impact of fires in that concrete area of the Peninsula must be sought, Azcárate points out, on the ground and orography. “The region has acidic and little fertile soils. This favors more flammable plant communities, due to the composition of plants’ tissues,” The expert reflects. At stake also enters the orography of that region, marked by an “abrupt relief” that hinders the access of “erratic and strong” seals that can abruptly change the direction of the flames. A few years ago Civio analyzed The main fires recorded in Spain throughout the 2007-2016 decade and discovered that in almost 80% of cases (153 of 196) the gusts exceeded 30 km/h, which could influence the evolution of fire. Something more than weather and orography. Not everything is climate, meteorology, orography or soil characteristics. In the fires it is influencing another factor than You are talking a lot During the last days: the depopulation of the rural one (which is usually accompanied by the abandonment of fields and a change in forest management), something that starts from the provinces of Ourense, Zamora and León They know well. “In general in Spain there has been rural, population and peoples abandonment and depopulation is a food for fires,” Celso Coco warnsfire expert and forest management in The opinion-the mail of Zamora. And what does that suppose? “The consequence is that in those areas where it was worked, it was grown, it was granted, natural vegetation has been installed and there is no use of them, which has increased the forest area greatly. This continuity of vegetation, without management, results in a vulnerable landscape,” duck. In their opinion, forest fires “have existed, exist and exist” and constitute “a natural process”, but changes in the landscape have affected their impact: where they were previously found with land … Read more

These are the most loved and hated millionaires, explained in a graphic

by

The most famous billionaires are not just business leaders, they have also become In media figures. Names that resonate in all homes and even influence In the political sphere. But there is something that clearly differentiates them: not all of them enjoy the sympathy of 99% of the world population that is not millionaire. While some generate admiration and respectothers generate very obvious opinions and levels of distrust and rejection. A survey Made by Reuters and Ipsos He asked 4415 American adults his opinion about some of the most outstanding millionaires of the Forbes Millionaires List. Some showed favorable opinions about them, others clearly unfavorable and others simply shrug because they had no idea who those gentlemen were. The portal Visualcapitalist He has collected all this data and has represented them in a much more enlightening graph that shows that, Being rich and famous does not guarantee to be popular Among your neighbors and countrymen. Warren Buffett and Bill Gates: Population favorites The Nonagenarian Inverter Warren Buffett, known as the “Oracle of Omaha”, leads the list of billionaires with greater popularity In the United States. His Austera and close personalityhas made 52% of the interviewees have a favorable opinion about the veteran millionaire. Only 26% of those who recognized him showed a negative opinion about him, and 18% recognized not knowing who that person was, despite having the fifth greatest fortune in the world. Buffett has been able to win the support of society Thanks to your simple lifestyle, your responsible investment approach and your commitment to philanthropy. Despite its imposing fortune of 165 billion dollars, its image transmits humility and common sensewhich makes it a reference well seen by many. For its part, Bill Gates is the great surprise of the table, occupying second place in terms of popularity, with 49% positive opinions. This perception has improved significantly from Gates left Microsoft’s direction And he put all his endeavor in philanthropy Through the Gates Foundation. However, with 43% of unfavorable opinions, its rejection index remains elevated. Gates has managed to position himself as a leader who seeks global solutions for problems Like public health and Climate changebut those causes have also put him in the spotlight of conspiracy theories The most diverse. That has made Microsoft the founder loved and hated almost in equal parts. For better or worse, Gates is one of the most popular millionaires in the world. Only 5% of the interviewees claimed not to know who that man was who claimed to have a assets of 108,000 million dollars. Musk, Zuckerberg and Bezos: Famous, but hated Despite being in the top 3 ofThe greatest fortunes in the world According to the Forbes list, Elon Musk, Jeff Bezos and Mark Zuckerberg face the challenge of being widely recognized, but very little dear. You can’t have everything. Elon Musk, with a fortune of 357,000 million dollars, has 39% favorable opinions. However, your participation in the Government Efficiency Department (Doge), in charge of saying goodbye hundreds of thousands of federal officials have won all A animated wave that has left him with 55% of unfavorable opinions. However, Musk is not the only one has not managed to connect With public opinion. Jeff Bezos also records 55% of unfavorable opinions in the survey. Unlike Musk, Bezos only awakens sympathies between 29% of respondents. The rest of the interviewees missing to complete 100% of the bar of Bezos sympathies and hatred I simply did not know who it was, although most likely they have ever bought in their online store or seen a series on their video platform. In the case of Mark Zuckerberg, the figures are not encouraging. Despite having experienced A complete image change To tune with the rest of the members of his generation, the founder of Facebook stands as the billionaire with the highest percentage of rejection of the list. His image has been damaged by scandals related to Users privacy and the Influence of social networks In society, which has made its popularity fall leaving 64% of unfavorable opinions. Definitely, Mark Zuckerberg doesn’t like. Millionaires that neither fu nor fa Despite being key figures in the technological world, billionaires such as Steve Ballmer, former Microsoft ex-care; Larry Ellison, founder of Oracle; And the co -founders of Google, Larry Page and Serguéi Brin, are not as recognized by the general public as Elon Musk or Bill Gates. In fact, 65% of respondents He doesn’t know Steve Ballmerwhile Page and Brin They could walk quietly through a shopping center and 69% and 72% respectively of the people with whom they were crossed would not recognize them. However, among those who do recognize them, the perception is very divided. For example, Larry Ellison has only 13% of favorable opinions, while Steve Ballmer has a modest 16%. It is probably because they have not seen their Microsoft marketing campaigns in the 90s. This contrast shows that, although They founded influential companies And their contributions have revolutionized entire sectors, the lack of media exposure and polarization in public opinion makes them less relevant characters at the popular level. Reuters data reveal that the perception that Americans have about their richest billionaires not only depends on the size of their fortunes or that of their companies, but also measured by their personal decisions. On the other hand, those who maintain a low profile, such as Larry Page, Serguéi Brin and Larry Ellison, seem to live in a limbo of popularity, in which they can enjoy all the Advantages of being centimillonario, Without the inconveniences of being so recognizable like Elon Musk or Bill Gates.

The migration of billionaires in the last decade, explained in an illustrative graphic

by

In the last decade, we have seen interesting changes in the Formation of new fortunes around the world and how new technologies were replacing oil, logistics or industry as origins of that wealth. However, these fortunes do not have to remain exclusively in a single country so, such as migratory birds, billionaires also They move around the world looking for the best conditions To develop your fortunes. Migratory fortunes The report ‘Billionaire Ambions Report 2024 ‘ Prepared by Financial Entity UBS has studied the movements of the great fortunes between 2015 and 2024, observing some patterns that reflect the economic policies that the different territories have taken and the effects that these policies have on the great assets. To help us have a more global vision of the subject, in Visualcapitalist have developed a graph with the data of the Migratory study of great fortunes of ubs. According to the report data, since 2020, about 176 billionaires, which in total totaling a joint assets of more than 400,000 million dollars, have moved to other countries. This means that approximately one in 15 billionaires in the world has changed residence Looking for more conducive airs for your fortunes. The reasons why they move are varied, but mainly they look for tax advantages and places where is easier do business. China, Switzerland and the United States are some of the most popular destinations for these ultra -ups. On the other hand, Eastern Europe has seen the largest exit of billionaires in the last ten years. China leaves a positive multimillionaire balance The case of China is quite paradigmatic since it has become the country that has won the most billionaires in net terms during the last decade. According to UBS records, in 2024, China had 501 billionaires in total. During the years that monitors the study, 73 ultrarricos moved to China from other countries, while 48 millionaires undertook the opposite path abandoning the country. The result is a positive balance of 25 billionaires for China. Despite the recent economic problems caused by the Real estate crisis in Chinathe total richness of its billionaires has doubled since 2015, reaching 1.8 billion dollars. Western Europe is the second region that has attracted the most billionaires in the last ten years, registering an increase 20 millionaires. In total, the billionaires of this region accumulate a joint wealth of 2.7 billion dollars, growing 16% since 2023. With 117 millionaires, Germany is the country with more population of millionaires from Europe, followed by Switzerland with 85 billionaires and the United Kingdom with 82. On the other hand, the growing geopolitical tension that Eastern Europe lives, and the subsequent outbreak of the Ukraine War, He encouraged the move of 29 millionaires from that area of ​​the continent. The United States has also been an important magnet for great fortunes, attracted to Innovation and investment poles as Silicon Valley and New York are. In the last 10 years, 55 foreign billionaires moved there, while 42 American millionaires left to other countries. With the boom in the stock market in 2024, the United States housed 835 billionaires with a combined wealth of 5.8 billion dollars, which represented a growth of 27.6% in one year. The fiscal policies that They have adopted Texas or Florida, are leading that some of the millionaires who were based in California or New York Rumbo to the south of the country. Middle East is in full reinvention process, with projects like Neomwhich seeks to unlink the richness of the country of its fossil resourcesturning countries as United Arab Emirates, into the right environment for investments and the creation of companies. A proof of this is that the richness of the billionaires of that country increased by 39.5% between 2023 and 2024. That favorable investor environment It has served as a magnet to host Millionaires from Southeast Asia, Australia or the South American cone, attracted by a most lax fiscal policy With capital income.

Some GeForce RTX 50 graphics cards are missing rop units. Nvidia has explained why

by

The family of graphics cards GeForce RTX 50 developed by NVIDIA continues to occupy the Center for Care in the field of PC hardware some more than a month and a half After your presentation. On this occasion we do not propose to talk about how difficult it seems to be to achieve one of these graphic solutions; We invite you to investigate A manufacturing defect which affects a small amount of GPUs installed in these graphics cards. Shortly after their launch some users observed that the number of rankization units, identified in English as ROP (Raster Operations Pipeline either RASTER OUTPUT PROCESSOR), integrated in some GPU GeForce RTX 50 was lower than that indicated by NVIDIA in the specifications. These units are responsible for executing the operations required by the rendering by rankization with the purpose of delivering the images formed by the final pixels to the monitor. Nvidia explained what is happening Several buyers They assure that their GeForce RTX 5090 and 5070 TI have a number of functional ROP units lower than the one indicated in the specifications. Days later a user of Reddit He denounced this same problem on his graphics card with GPU GEFORCE RTX 5080. In the latter case the graphic chip should integrate 112 ROP, but that particular card incorporates only 104 ROP, which has a downward impact on its performance. “Affected consumers can contact the graphics card manufacturer to obtain a new one. This production anomaly has already been corrected” Unfortunately it is not possible to solve this problem by resorting to an update of the BIOS or the controllers because it is a hardware defect. Nvidia has confirmed Tom’s hardware that, in effect, the problem exists, and that It is a manufacturing defect which affects a small amount of GEFORCE RTX 50 family chips. According to the company led by Jensen Huang, the amount of affected graphics cards is somewhat less than 0.5%. “We have identified a rare problem that affects less than 0.5% of the GeForce RTX 5090, 5090D and 5070 TI. They have a lower ROP than specified (…) The average impact on graphic performance is 4% and does not affect the workloads of artificial intelligence (AI) and calculation. Affected consumers can contact the graphics card manufacturer to obtain a new one. This anomaly in production has already been corrected “, explains the official Nvidia statement. The ideal in these circumstances is that all players who have bought one of the GeForce RTX 50 that can presumably be affected by this anomaly in the manufacturing process check if Your GPU has appropriate rop units using Techpowerup Gpu-Z or other similar diagnostic application. If your GPU is one of the defective ones they have the right to claim the change of their graphics card in the store in which they have bought it. An important note: some Founders Edition cards sold directly by Nvidia are also affected.

Tired of people talking about the end of the world without knowing, Newton decided to calculate it. And he explained it in a letter of 1704

by

By 1665 the bubonic plague arrived in London in a cotton ship from Amsterdam. In the following years, between overcrowding, dirt, hunger and rats, they would die More than one hundred thousand people In the country. In August, the great plague arrived in Cambridge and forced the university to close. It was then that a very young Isaac Newton had to return to Woolshorpe Manor, the family home. Over there, According to a probably fraudulent traditionsat down one of the three apple trees of the farm and the blow of one of the fruits brought to mind the theory of gravity. We do not know if the craniocerebral trauma produced by the happy apple was also responsible for everything that came in the last part of his life. Sir Isaac Newton was not any. On the one hand, Newton was, in fact, an intellectual giant. “The greatest scientific brain that the world has known,” According to Asimov; the person responsible for that “perhaps the greatest advance of thought that a single individual has ever done”, According to Albert Einstein. “Nature and its laws were hidden at night; God said ‘that Newton’ becomes and made the light,” he says Alexander Pope’s famous epitaph. On the other, it was someone complicated – especially after The nervous breakdown he suffered in 1693. The most controversial example is its passage through the house of La Moneda de England (a stage of your life Full of torture, hanging and dismembered falsifiers); However, a brief review of his personal life and friendship gives good account of it. But what interests us today is that he was passionate about the Bible. It is estimated that more than half of what Newton wrote It had to do with theology and alchemy; And, as a good mathematician, one of the themes that worried him most was the end of the world. The end of the world? Yes, at that time (remember that The English revolution had just “finished”) Religious debates were in the flower. And the end of the world was a usual issue in public conversation. But Newton was convinced that people did it wrong. Lincolnshire’s genius analyzed the biblical text (And, specifically, Daniel’s book and the Apocalypse) and concluded that people were exaggerating the closeness of the end of the world. And gave a date? Yes and no. As Newton seems to identify the year 800 d. C. as the moment when the Church entered the “great apostasy.” This is a key date in the texts and, from there, he deduced that there was no reason to think that before 1260 years the apocalypse arrived. That means that We are relatively safe until 2060. Because, as he said “he may end later, but I don’t see any reason for him to end before.” But did he really think he was going to end the world? According to Stephen Snobelen, professor at the King’s College University of Halifax (Nueva Scotia) that has studied the matterNewton did not believe that the world would end in a literal sense. “For Newton, 2060 AD would be rather a new beginning. It would be the end of an ancient era, and the beginning of a new era: the era to which the Jews refer as the messianic era and the era to which Christians premillennials call the millennium or kingdom of God “, Snobelen defended. Obviously, we are not faced with weight to think that the apocalypse is just around the corner. But knowing The close we are from the end of the worldwe can take all this as an invitation to take advantage of the moment.

General Manager of the Dodgers explained the development plan that Roki Sasaki will have in Major Leagues

by

Los Angeles Dodgers signed the large league prospect. This is the Japanese pitcher Roki Sasakiwho will join the current league champion in a rotation full of stars, including Shhehei Ohtani. That is why the Californian team directive will carry the evolution of the 23 -year -old pitcher calmly. And for this they have a development plan that recently Brandon Gomes, general manager of the Dodgers, explained in an interview for the Podcast Baseball Isnt Boring. “Our priority with him (Roki Sasaki) is to ensure that he adapts to this new challenge and that we can direct him to success”began the team manager about the plans they have for the young Japanese pitcher this season. Roki Sasaki won the World Baseball Classic with Japan.Credit: Eugene Hoshiko | AP “I think the most important thing is to get our coaches, performance personnel, launch trainers to have it in our hands. Now it’s about getting it and talking to him along the way, making it very clear that it is an association, ”Gomes followed. And it is that Dodgers expect to give Sasaki a lot of rest. Especially with the return of Ohtani, so the team could have a rotation of up to seven openings in the season. “We are going to give a lot of rest and it will be something that we will continue to evaluate along the way. Obviously, when Shohei is back, it will be easier for us to do that and get additional rest when necessary ”assured the general manager of the Dodgers and added that they trust to be able to carry out the plan, because they have “the flexibility in the front with our depth and the number of players we have.” Sasaki will form a rotation in the Dodgers that will feature Blake Snell, Yoshinobu Yamamoto, Tyler Glasnow, Dustin May and the possible return of Shohei Ohtani and Clayton Kershaw. So at its young age it could be a key piece in a team full of stars.
