Of the seven wonders of the ancient world, there is one that we do not know where it is. That makes it the most fascinating of all

Of the Seven wonders of the world Old, alone The Great Guiza Pyramid is still standing. The others, destroyed since ancient times, They have left archaeological traces or detailed historical records. Except for one: The pendant gardens of Babylon. The structure is still involved in an enigma: without conclusive archaeological evidence or mentions in contemporary Babylonian inscriptions, its existence is a subject of speculation among historians. Between the myth and the lost wonder. The pendant gardens of Babylon have been for centuries A symbol of greatness and ingenuity of antiquity. The best known version says that They were supposedly built by King Nebuchadnezzar II in the sixth century ac As a gift for his wife Amytis, who missed the vegetation of his homeland. We talked about gardens that were described as a feat of engineering, with terraces covered with lush vegetation and an advanced irrigation system. The problem? That as we said, despite their status as One of the seven wonders of the ancient worldwe don’t have Not a single conclusive archaeological test that once existedwhich has generated a debate about whether they were a tangible reality or simply a historical exaggeration. Moreover, Not even Herodoto, the “father of history”, mentions them in His descriptions of Babylon. Plus: The sources that support this theory are Greek and Roman, written centuries after the supposed existence of the gardens. In this regard, Flavio Josephus, based on the Babylonian Babylonian priest, described a “pendant paradise” within the walls of Babylonbut, again, without contemporary evidence, this story remains uncertain. Babylon: the city (above); The pendant gardens of Babylon (below) The mystery of its location. Although tradition places the gardens in Babylon, near the current to Hillah in Iraq, excavations have not found concrete evidence of it. The German archaeologist Robert Koldewey thought he had found his foundations in a vaulted structure In the South Palace, with robust walls and evidence of wells, but today most experts rule out this theory, suggesting that it was actually a warehouse. Gardens Representation Another hypothesis. Raised by academic Stephanie Dalleyfrom the University of Oxford, the story suggests that the hanging gardens They were not in Babylon, but in Nineive, north of Mesopotamiaand that they were the work of King Assyrian Senaquerib. According to their analysis of cuneiform inscriptions and reliefs that show channels and vegetation in Nineveh, the Assyrians would have built monumental gardens with an advanced system of aqueducts and water elevation. The “but”: the confusion in this case, Dalley holdsit originated when the Assyrians conquered Babylon in the 689 AC, Reboutizing Nineve. In other words, this theory raises the possibility that ancient historians confused the monarchs and territories in their stories. So myth or reality? As we said, the descriptions of the gardens They speak of a series of terraces supported by stone columns and a complex hydraulic system that allowed irrigation in full desert. Some scholars consider that such structure would have been difficult to sustain with the technology available at the time, which reinforces the possibility that its existence could have been a propaganda myth to enlarge the power of Babylon. The unfathomable wonder. Thus, if the gardens really existed, their disappearance remains a real mystery. Estrabón mentioned that for the first century ac were in ruinsand some suggest that Alexander the Great planned to restore them before his death. Over time, as some point, changes in the course of the Euphrates River could have buried any evidence underwater. If you want also, and despite uncertainty, The legend of hanging gardens He has endured as a kind of symbol of human ambition to create beauty in hostile environments. Be a myth or a lost wonder, its history continues to captivate generations of explorers, historians and dreamers. At least, a privileged place in history has been secured as The most enigmatic of the seven wonders of the ancient world.

MIT has measured for the first time the geometry of electrons in the quantum world

The paths of quantum physics are inscrutable. In my opinion 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 this discipline: “If you think you understand quantum physics, 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. He Mit (Massachusetts Technological Institute) has just been a bit very important. Physicists now better understand the quantum properties of the materials A group of MIT researchers has managed to measure accurately at the quantum level the geometry of electrons in solid materials. Expressed in this way it does not seem much, but it is a very relevant discovery. Until now, physicists had managed to measure the energy and speed acquired by these elementary particles in crystalline materials, but not their geometry at the quantum level. According to Riccardo CominProfessor of Physics at the MIT and leader of this research, “this discovery allows us to understand and manipulate the quantum properties of the materials.” Quantum geometry allows physicists to determine the geometric characteristics of the wave function Before moving forward we are interested in briefly investigating the concept of ‘quantum geometry’ to be able to understand with some precision what we are talking about. Its purpose is to describe the structure of a quantum system such as the forming, for example, by The interaction of electrons In a solid material. In practice this knowledge serves to elaborate a map that describes the probability of finding an electron in a given position. Rigorously this “map” is known as wave function. However, this is not all. Quantum geometry also allows physicists to determine the geometric characteristics of the wave function. This simply means that with this information you can know how precisely the electrons behave in a material and to what extent their properties condition. Quantum geometry helps scientists, in short, to predict the behavior of materials and design new elements or combinations of elements that can be used in aeronautics, Quantum computing or robotics, among many other disciplines. Riccardo Comin assures that “in essence we have done is to develop a plan to obtain completely new information (about the materials) that until now could not be collected.” And Mingu Kang, another of the physicists who have signed the article published in Nature Physics, duck That “this knowledge It can be applied to any type of quantum material“. The technique that these scientists have used to develop their strategy is known as photo emission spectroscopy resolved at an angle. In broad strokes it is an experimental procedure that serves to study the electronic structure of materials in a thorough way and know their fundamental properties.

Openai brings to the EU the ‘Live Camera’ mode to see the world in real time

“I see that you wear a hoodie.” This is a fragment of conversation that Chatgpt And an OpenAI employee maintained just over eight months ago. The company of artificial intelligence (AI) led by Sam Altman presented his new model GPT-4O And he showed us how he could help improve his famous chatbot. At some point, Chatgpt could use the camera of our device to see the surrounding environment and, consequently, offer us a deeper experience. Something like what we saw in the movie ‘Her’, saving the distances. This mode landed first in the United Statesand now it is deploying in the European Union. Hello, chatgpt. What do you see? The novelty, known as’Live Camera‘It is a complement to the advanced voice of Chatgpt, a very promising combination of technologies. In another of the demonstrations shared by the company We have seen the chatbot knowing a puppy named Bowser or helping to learn Spanish to some users. We are facing a tool that can also be very useful for people living with some blindness or visual disability. Since the way of vision You can identify objectsyou can describe in natural language what is in front of the camera. The underlying technology, GPT-4O, also promotes the app Be My eyes. Chatgpt’s real -time vision vision It should be noted that the novelty that is being deployed today allows us to share with chatgpt what is on our screen. So the model could help us solve, for example, mathematical problemsas we have seen In other videos shared by OpenAI last year during the initial announcement of the tool. The activation icon and the welcome screen of the Live Camera mode Well, now that we know everything we could do with the latest of Chatgpt the question is how we can start using it. In the first place, we will have to keep in mind that it is a payment feature, that is, it is available for Chatgpt Plus users ($ 20 per month) and Chatgpt Pro (200 dollars per month). Theodore falls in love with Samantha in ‘Her’, a movie released in 2014 If we meet this requirement, we will only have to make sure to have the updated application. We open the application and click on the lower right corner button to activate the advanced voice mode. We will meet the camera button Below the left, an element that we must press to begin the action. Chatgpt will remind us that it is an option that is in the beta phase and the system will possibly ask us permission to access the camera. If we agree, we accept and begin to interact with this most advanced version of the chatbot. To share the screen in real time, click on the three points and then the corresponding option. It is important to keep in mind that paying for Chatgpt Plus does not provide unlimited access to these functions. So we will have to adapt to whats Use limits newspapers established by OpenAI or, in case our budget allows it, pay $ 200 per month for Chatgpt Pro to use these models without limitations.

Arturo Coello, number 1 of the world paddle for: “Life separates people into two paths, those who party and those who dedicate ourselves to sport”

Updated Tuesday, January 28, 2025 – 23:36 Arturo Coello It is the roof of the world paddle. For his height, 190 centimeters that scare their rivals, and for their position in the Ranking of the International Paddle Federation. This Valladolid of 22 years Share number one in the world with your partner on the track, the Argentine Agustín Tapia. They won 14 titles Last season and start at this beginning of the course as great favorites to the annual throne. The campaign starts next February 8 in Saudi Arabiabut before, the big stars of world paddlers are cited this week at Madrid Arena for the Hexagon Cupa tournament in which teams compete for celebrities from the world of sports, who are choosing for their templates the best paddle players in search of a Award this year exceeds one million euros. «It’s going to be a beautiful week. I will have Agus in front and we are clear that it is a team competition, but we always have a good time, ”says Coello in the halls of Madrid Arena. Spanish represents Team Bellawhile Tapia, his partner in the circuit, is part of the ‘RL9’, with Lewandowski as president. Next to them will be the team of the Rafa Nadal Academythe ‘Advantage’ team, owned by the extenist Andy Murray and the boxer Anthony Joshua; ‘Krü paddle‘, of the Kun Agüero; ‘Eleven Eleven’, from Eva Longoria; and ‘X10’, of the Formula 1 pilot Pierre Gasly. The tournament, which has the sponsorship of the team Alpineenters its second edition and has expanded the teams while studying to entry more presidents, given the high interest that the paddle and tournament awakens. Coello is clear who would be a great signing: «I would like to see Cristiano Ronaldo hereI have already played with him. I am trying to convince him to get into the world of paddle and next year enters the tournament with a team, ”admits the athlete. “Until 15 years this was a hobby” In a talk with the world, Coello reflects on what life has changed in recent years, coinciding with the media explosion of the paddle world with his arrival to the professional circuit. «Paddle has evolved a lotbut I remain the same person and I still make the same life. It is true that more people know me and the impact I have is different. I have to be more careful with the things I do because I am obviously more visible to children and it is a beautiful responsibility. It makes you more respect for the things that are happening to you, ”explains the young player. Coello is part of this new generation of paddle stars that were installed in the elite in an era of economic bonanza, far from the hardships that other legends passed such as Fernando Belasteguín or Paquito Navarro. That makes him have even more professional speech. He grew between shovels until with 15 years he decided that the paddle was going to be his life. Miqui move «Until 15 years for me it was like a hobby, nothing more. But from that age I decided not. There life separates people into two paths, those who They start to party and begin to study and those who We dedicate ourselves to sport. In my case I was very clear that mine was going to be the sport, I left many things aside that are hard to pass, but I am also living others that the rest of the people cannot live. I wake up, I do sports And I’m lucky to be able to dedicate myself to what I like, ”he develops. Despite his youth, he has noticed firsthand the evolution of the paddle and has ended moving to Miami To have its operations center there: «The demand for number one is very high and every detail counts. We are very focused daily on that demand. We are going to Miami for having better facilities than those I had in Madrid, but my team does not change, I will have the same coaches and trainers and I will see Agus in the tournament weeks, as always ».

The world commemorates this Monday (27.01.2025) 80th anniversary of Auschwitz’s releasewith the assistance of some of the few survivors who remain at ceremonies in the place of the sadly famous Nazi concentration camp. Auschwitz was the largest of the extermination fields And it has become a symbol of the genocide of Nazi Germany against six million European Jews, one million of which died in the place between 1940 and 1945, along with more than 100,000 non -Jews. This Monday, the Polish president Andrzej Doubt he deposited Flores in the place next to the survivors, some of them with scarves with the blue and white stripes of his uniforms of the extermination field.

Cooperate for your good: why the clash with Petro is a Trump message for all world leaders

Image source, EPA Photo foot, The Trump government made Petro accept the terms of the deportations of migrants to Colombia. Article information Author, Anthony Zurcher Author’s title, BBC News 4 hours Less than a week after assuming the presidency, Donald Trump generated his first international tariff dispute. And the objective was not China, Mexico or Canada, frequent whites of its anger, but Colombia, one of the closest allies in the United States in South America. The crime of Colombia was to refuse to allow the landing of two American flights that transported deported migrants because they were military and non -civil planes. That seems to have been enough for Trump to release the hammer. “We will not allow the Colombian government to violate its legal obligations regarding the acceptance and return of the criminals who forced to enter the United States,” Trump published in his social media site. In addition to the 25% tariffs they offered to impose, Trump said that the United States would introduce a travel ban and would “immediately” revoke the visas to Colombian government officials, as well as their allies and supporters. At the last hours of Sunday, however, the Petro government announced that it had overcome the “Impasse“With the White House and declared that he would accept to receive migrants deported by the United States. During his first week in office, the US president seemed to prioritize migration executive measures over commercials, even if the latter were a key campaign promise. To emphasize that point, for the first time the president used tariffs to punish a country that, in his opinion, did not support the new hard line migratory policies of the United States. On a day when Trump had no planned public appearances (he is in his Miami resort, after having played golf in the morning), the president decided to give an example with Colombia. And with this, Trump is sending a warning to the allies and the adversaries of the United States equally: if they do not cooperate with the United States, the consequences will be severe. Image source, COURTESY OF THE WHITE HOUSE Photo foot, The White House published images of deported migrants in military aircraft. Work with other countries Although finally the Petro government accepted the terms of deportations after the president criticized his American counterpart in social networks, incoming officials have indicated that the United States immigration policy will require looking beyond the border with Mexico. The Trump candidate for Undersecretary of State, Christopher Landau, has long sustained that “working with other countries to stop those migratory flows” must be a “global imperative of US foreign policy.” However, Sunday’s dispute could make work together. Every year, tens of thousands of migrants from around the world, from India to China, go to the United States after landing in South America and traveling through the Darién cap, a key point in the north of the border with Colombia , and share with Panama. It is a dangerous trip, in which migrants usually face the presence of criminal gangs. Image source, Reuters Photo foot, The intersection of migrants for the Darién plug is a sensitive issue of discussion between Colombia and the US. United States retaliation measures could make Trump government work with Colombia on this issue. Petro alluded to this in his response to Trump’s actions, pointing out that if conversations about migration management through Darién are suspended, “illegal activities will increase.” These comments could be interpreted as an evening threat that more undocumented migrants will come. Petro hastened to say that his country would not reject the deported Colombian citizens of the United States, only that they should receive a “dignified treatment.” He even offered the use of his presidential plane as a means of alternative transport. However, the Colombian president was forced to accept the terms of deportations, after retracting in his position to respond to the United States with the implementation of tariffs similar to American products imported to Colombia. Although it was a Sunday of great drama, this sudden diplomatic confrontation was resolved. In any case, tariffs are proof of will. And Trump showed that this would be just his first movement.

A solar solution to supply the world with 22 Energy TW

A recent Ember report explained how Europe had eliminated coal as an energy source in 2024 and gave way to renewable energies, such as solar. In fact, in the same analysis, Spain registered a continuous increase in photovoltaic generation, reaching 21% of its electricity almost double that the European average (11%). So far everything is fine, but this boom of the solar is carrying that alternatives for the installation of panels in other surfaces, such as aquatic. International investigation. A study group, led by Carlos D. Rodríguez-Gallegos, has evaluated The state and potential of floating photovoltaic facilities (FPV) worldwide. For this analysis they have used the largest global database that collects the information of 1,142 commercial FPV systems from 2022. In addition, they took the geographical references of reservoirs, which cover a total area of ​​more than 2.2 million square kilometers. The object of study is to analyze its implementation and performance, in addition to studying advanced configurations such as bifacial panels, inclination angles and monitoring systems. The investigation had contributions from researchers from the You will be Singapore and from the National University of Singapore (NUS), as well as the Polytechnic Higher School of the Litoral de Ecuador, the Polytechnic University of Hong Kong, the Concordia University of Canada and the University ofokin of Australia. Asia, the leader. Almost 90% of the installed floating solar capacity is in the Asian continent and China leads it with almost half of the accumulated capacity. This world predominance is due to favorable, ambitious objectives focused on renewable energy and regulations designed to support the expansion of FPV. Although Asia leads the development of floating solar panels, Africa is also exploring this technology. Zimbabwe advance with a 250 MW plant In the Kariba dam, projecting to reach 1 GW. In Ghana, A 5 MW system In a reservoir it will be expanded to 15 MW, while Cape City, in South Africa, has completed several smaller projects. With abundant sun and limited water resources, Africa seeks to meet your energy needs through these initiatives. Take advantage of water areas. The installation of photovoltaic systems on aquatic surfaces has presented different benefits, according to the study. First, optimization of limited space in areas with scarcity of earth. In addition, FPVs help reduce the evaporation of water in reservoirs and to maintain the temperatures of the lowest solar panels, improving their efficiency. On the other hand, this technology avoids related conflicts about land use. To give an example, in the Swiss Alps, They have demonstrated that these facilities can prosper even in adverse conditions, reaching higher performance regardless of altitude. The study results. From the analysis that the average size of the FPV has increased in the last ten years of 0.09 MW in 2013 to 1.40 MW in 2022, and, in parallel, the average power density has gone from 82 W/m² at 123 w/m². Researchers have identified optimal configurations to maximize electrical performance, such as the use of solar monitoring systems and bifacial panels, which capture the reflected light, thus improving energy generation. In economic terms, FPVs have proven competitive. For example, the project director has signed up for an Indian initiative that achieved a cost of installation of just $ 0.41 per watt, which reinforces the economic viability of this technology against other renewable energy options. However, these facilities also face certain challenges such as the initial cost can be very high by infrastructure. In addition, technology adaptability to different bodies of water (sweet or salty) and logistics complexities can also increase costs. Looking at the high seas. Looking ahead, the research team plans to explore FPV applications on the high seas, investigating its energy potential, innovative designs and the challenges that costs and maintenance present. According to its estimates, covering only 10% of the surface of 249,717 continental reservoirs could generate a capacity of up to 22 TW, sufficient to satisfy all world consumption of electricity and up to 5% of the global water demand.
