We already have so many “humanoid” robots that it costs to differentiate some of the tros. This chart fixes it

We are determined to create robots that look like us. It all started in 1980 with a original Boston Dynamics that already had prototypes of robots capable of Give mortal jumps and walk to Pata Cojawith designs that would later be recovered for wonders such as Spot. The industry has advanced a lot in these 30 years and of those robots almost from the science fiction of the 80s, we have moved to humanoid robots with amazing abilities. And in this graph prepared by Visual Capitalist We can see some of the most representative in recent months: Police photo. The Boston Dynamics HD Atlas was the one that began this fever for humanoid robots. We have seen it do everything, but life is hard and The time for retirement arrived. A new generation, the new Atlas, stronger and capable of its joints, reached the company’s testing field now owned by Hyundaibut as can be seen in the graph, it is not very different from the rest of the competitors. Chinese models are missing. In this kind of police file, we have a majority presence of American robots, being the PHOENIX of Sanctuary AI and the H1 of Unitree the only ones who are not Americans. And yes, it is true that US companies are very focused on the creation of these devices, but many China models are missing. The Asian giant is immersed in a technological revolution (despite the severe western restrictions) and has within its borders companies that They are competing Not only to create robots to integrate into your society, but do it on a large scale. One of the maximum exponents, apart from the UNITREE H1, is the Agibot company with the models A2 and A2 Max. Like Americans, they have a IA processor that allows you to collect data from abroad and act accordingly. In addition, these models are multimodal, so they also understand information provided through text or audio. There are also the Robothera Star1 (considered the fastest in the world), the Ubtech Walker S1 or the GR-1 of Fourier Intelligence. China wants to work. Despite all those absences, it is clear that we have been seeing demonstrations of these robots for years, but few examples of them performing the work for which they have been programmed in the real world (with exceptions like BMW’s figure). It is precisely China where the accelerator are most treading at the moment due to the need. The GR-1, for example, was programmed to exercise as a nurse with the aim of responding to a need: The country is increasingly old And there is no generational relief capable of taking care of their elders, or who wants work in some industries. The intention of the country It is to create a National Network of Services for the Elderly in 2029 with the aim that all older citizens have access to basic services. Among the tasks of these robots, are domestic services, health monitoring or emotional company. But we can not only talk about humanoid robots, since China too He is testing robots ‘Lazarillos’ And it has its own spot working as a mobile paper. 2025 looks like the year. The interesting thing is that, beyond the tests in some scenarios in China and the United States, the main players in this segment are clear that 2025 should be the year in which the explosion of robots begins. At the end of 2024, Agibot said they were ready for their robots to take the streets thanks to 1,000 models produced; Tesla wants to produce in mass Optimus gen 2 This 2025, with between 50,000 and 100,000 units Facing 2026 And the Chinese government itself marked 2025 as a target year so that the robots of their companies are available to buy. I, robot. There are many other companies, such as the Norwegian 1x with their Neo Beta and Neo Gamma whose objective will be to clean the house that are also in this wave of robotics, but beyond the companies that aspire to create mass robots this 2025, there are others that want to get into the car in one way or another. An example is goal, Mark Zuckerberg’s company that is betting strongly to the development of artificial intelligence and that, precisely, wants Its AI is the brain of some of these robots. And, speaking of great technological ones, We have Apple’s examplewhich also seems to be looking for the way to put the leg in the home robot segment, with a device similar to An iPad with robotic arm First and humanoid robots as a final objective. In the end, as we say, after years of demonstrations, it seems that 2025 will be the year in which robots will cease to be simple fair attractions to integrate into our day to day. In the day to who can and want pay themclear. In Xataka | You don’t need to blow your coffee too hot. This little “pet robot” does it for you

Cal Newport strategies to achieve the impossible in less time

Notifications interrupt. The meetings proliferate. The entrance trays They devour time. In this digital ecosystem, sustained concentration has become scarce and valuable. Cal Newport called him “deep work” in his book ‘Centrate’ (Deep Work): This state of concentration without distractions that allows to solve complex problems. There is something paradoxical here: the knowledge economy demands more deep thinking, but our digital tools actively work against it. Look at the use metrics of your phone. How many notifications do you get up to date? Surely more than 100, possibly more than 200. Each is a microinterruption. Recover the concentration after It is not immediate. We often enter that state that we could define as “being busy but without advancing.” We confuse activity with productivity. Before smartphone, prolonged concentration was almost a basic ability. Today is An act of resistanceIt is almost a heroicity. Great innovators apply in their own way of deep thinking. Steve Jobs boasted of his contemplative walks. Bill Gates, of his “weeks of reading” a couple of times a year. There is something. What does Cal Newport suggest to incorporate time of this type into our lives? Program deep work. Block specific time for tasks that require total concentration. Minimize context change. Each jump between tasks consumes mental resources. Grouping similar tasks reduces this “cognitive tax.” Create rituals. The will is limited. Rituals automate decisions about when and how to work. Embrace boredom. Our aversion to be disconnected erodes our ability to attention. Boredom has its advantages. Audit tools. Not all technology deserves a place in our professional life. Basecamp or Shopify have already implemented measures such as Days without meetingsor a firm commitment to asynchronous communication. Deep work offers something that empty trays and completed tasks cannot: meaning. The psychologist CSIKSZENTMIHALYI called him “flow“: That state where time disappears and work becomes its own reward. The need to think deeply is no longer a strategy to copy Newport, it is almost an intellectual need. In Xataka | Nobody says that he knows how to read in the curriculum.

characteristics, price and technical file

Although we already had a good ration of Samsung at the beginning of the year with the Unpacked of the Galaxy S25the Korean company has not let the opportunity to announce new devices within the framework of the MWC 2025. If we already had the high range on the table, what made sense is that Samsung took advantage of this event to renew its mid -range, and it has been. We already have among us the new galaxy A, being the most powerful, the Samsung Galaxy A56 5gwho stars this text. He Samsung Galaxy A55 5g It was, without a doubt, one of the star terminals of the Samsung catalog during the last year. The Galaxy A56 5G comes to collect the witness and update the Middle range. Because? Because although Samsung has taken it easy, the artificial intelligence that we have already seen in the high range finally reaches the most affordable models. At least partly. Thus samsung money earns: the secret is on the iPhone Samsung Galaxy A56 5G technical record Samsung Galaxy A56 5g Dimensions and weight 162.2 x 77.5 x 7.4 mm 198 grams screen Super AMOLED of 6.7 inches FullHD resolution Refresco rate: 120 Hz Vision Booster HBM: 1,200 nits CORNING GORILLA GLASS VICTUS+ processor Samsung Exynos 1580 GPU AMD XClipse 540 RAM 8 GB Internal storage 128/256 GB rear camera Angular: 50 MP, F/1.8, AF, OIS Great angle: 12 MP, F/2.2 Macro: 5 MP F/2.4 Front camera 12 MP F/2.2 battery 5,000 mAh Fast charge 45W Operating system Android 15 with One UI 7 connectivity WIFI 6E 5G SA/NSA GPS NFC USB type c others IP67 resistance Galaxy AI Circle to Search price 12/128 GB: 479 euros 8/256 GB: 529 euros A family design Samsung Galaxy A56 5g | Image: Samsung Samsung has not reinvented the wheel with its new Galaxy A56, but has taken what already worked and has updated it. Thus, we have a slightly larger device than its predecessor, Quite thinner (almost a millimeter) and significantly lighter (198 grams compared to 213 of the Galaxy A55). The rear retains that sober, but elegant finish, to which Samsung has accustomed us to a camera module somewhat more striking than that of the previous model. As far as the screen is concerned, Samsung has mounted a 6.7 -inch Super Amoled panel with FullHD resolution and up to 120 Hz of refreshment rate. It is a competent panel, at least on paper, and what attracts the most attention is its maximum brightness. Samsung has preferred not to get into the Nits War And, instead, he has opted for a safe figure and that works: 1,200 maximum brightness nits. The screen, by the way, is flat. Exy us under the hood (and finally, AI) Samsung Galaxy A56 5g | Image: Samsung If we open the hood we will see a processor Exynos 1580 and eight Gigas of RAM that we can combine with 128 or 256 Gigas of internal storage. The key, however, is not the power, but the software. The Galaxy A56 5g comes out with Android 15, One UI 7 And artificial intelligence leads to the most affordable prices, something that until now we had only seen in high -end models. He In fact, It is the Galaxy A56 5g that has more functionssince it is the only model that has “better face” and “Nightgraphy”. However, he shares with his brothers Galaxy A36 5G and Galaxy A26 5g the draft objects, the filters based on AI and Circle to Search. Samsung, however, has not mentioned Galaxy AI, so the deployment of AI functions does not seem total, but rather a first incursion with options more focused on creativity. Moreover, these functions of AI are more from Google than of Samsung, really. As for the battery, the Korean firm has managed to keep the 5,000 mAh capacity Despite the obvious reduction in thickness and weight. Fast charge is in the hands of a 45W power system. All this will boost Android 15 with One UI 7, as we advanced before, and will do it for longer. Because? Because Samsung has pledged to offer “up to six generations of updates of the Android and One UI operating system”, as well as six years of security updates. Triple camera with the basics Samsung Galaxy A56 5g | Image: Samsung We end with the camera. The Samsung Galaxy A56 5G incorporates a Main sensor of 50 megapixels With OIS, a great angle of 12 megapixels and a macro of five megapixels. The front camera is in the hands of a 12 megapixel sensor of resolution. It is a simple and known photographic lot in which we continue to miss the telephoto, something that is still relegated to the high -end models.

In search of the lost ark ‘, the answer is to pass it black and white

At this point, say that Steven Spielberg It is one of the best directors in the history of cinema, it is meaningless. Has shaped Incredible works And, without judging me which is your best movie, I am clear that the one I can see again, another and again without boring me is’In search of the lost ark‘. Not only is the first in the saga of Indiana Jonesbut also a round tape with humor, good argument, sharp dialogues and masterfully shot action. His initial scene with the great rock chasing the archaeologist is part of pop culture and I know I am not the only fan of this film. But I also know that not so many people have seen the black and white version, without sound and industrial metal sounding in the background. Because yes, ‘Indiana Jones: In search of the lost ark’ he has a version made by a fan. And that fan is a winning film director of the best director: Steven Soderbergh. The other Indiana Jones face Soderbergh is a peculiar director. He has films that have been a failure and are somewhat rare, surprises like the raw ‘traffic’ that made him deserving of the academy award and balls such as the saga ‘Ocean’s’. In addition to directing, produces, edits and is director of photography of many of his creations. Also those of others. The director has a blog in which he releases his thoughts, but between filming and filming, at some point in 2014 he thought something like “Has people really see the work so impeccable Spielberg at photography level?” Or something like that, go. Being a director of photography, some of this knows and something proposed: to make his version of one of the most mythical films in history: the aforementioned first installment of ‘Indiana Jones’. I have to admit that, of all the times I have seen it, I had never done it as when I saw the Soderbergh version. I focus on action, I look at the definition of the first planes, I let myself be carried away by the music of John Williams and I must admit that the grain and the color palette flips me. But never, and see that I like photography, I had given me to value that aspect of the movie. I of course was good, but with what Soderbergh did … there I realized to what extent Spielberg is a teacher. Because Stephen does not want to improve what Steven did. Not only would it be a disrespect, but a boldness. What he wants is, precisely, to exalize Spielberg’s work, that everyone can put aside the elements that have nothing to do with pure and hard photography. And, for this, he applied a series of changes to the tape. The first and most evident: it was the color. Not only did he put a black and white filterbut made it hard, accentuating the shadows until it is indistinguishable. It is what stands out the most, but as soon as reproduction begins, the second thing that attracts attention is that John Williams has disappeared. All the sound of the movie, really. The industrial and heavy music of Trent Reznor and Atticus Ross bathe each scene. Turning a Blockbuster As this in something similar to the silent cinema of German expressionism, Soderbergh wants us to concentrate on one thing: admire Spielberg’s hand and eye. Also be didactic and that those who are learning from cinema can do it with one of the best. In this link that leads to your blog We can see the full film in this format, and it is surprising that, beyond that you know it or not, only with the framing, the rhythm of the assembly and the movement of the camera, the argument can be followed so well. You can ride the dialogues in your head: the movie simply works. And be careful, it is not the only film that made an alternative montage. There is also ‘2001: Odyssey in space’but unfortunately that entrance was erased from his blog. The truth is that, in this case, Kubrick sure would not have made him a hint of grace. And it is also true that there are films that these changes feel better than others. ‘Logan‘It has a black and white version and I think it would also work if we take away the sound and focus on what we see. But – by saying another that hallucinates me – something like ‘Matrix‘, For example, I would not work at all with such a change, at least in my opinion. The color is tremendously important in the Wachowski tape. I will be delighted to read in comments what this version of ‘Indiana Jones’ “remastered” by Soderbergh. (And what amounted to me most is that you can see free being Disney’s rights).

Why keep doing sports in adulthood can save us a scare with hypertension

As we become older, having an eye on our blood pressure is becoming more and more important. We know that regular exercise is important in order to reduce the risks associated with high blood pressure; But how, when and how much of the sport is still a mystery. One that we are solving little by little. Save strength. An example of this is a study led by researchers from the University of California, San Francisco, focused on how the different levels of exercise that we reach throughout our life lead to greater or lesser blood pressure in later stages. The conclusion of the study was that maintaining high levels of activity as we approach the middle age is An important key facing a healthier future. “Teenagers and early twenties can be physically active, but those patterns change with age. Our study suggests that maintaining physical activity during our adulthood-coun (at higher levels of what was recommended) could be especially important, ” explained in a press release Kirsten Bibbins-Domingo, co-author of the study. The risks of hypertension. High blood pressure, or hypertensionit implies that the blood exerts high pressure on the ducts that transport it. Symptoms may include headaches, lack of air, or nasal bleeding, inter alia. The problem arises in the long term, however, since hypertension is linked to a series of cardiovascular risks, some of them potentially lethal, such as heart attacks. 5,115 participants. The study was conducted with 5,115 agent participants between 18 and 30 years old to whom a follow -up was carried out for three decades. The participants were chosen in the context of the cardia study (Coronary Artery Risk Development in Young Adults) in urban nuclei from different areas of the United States. In its study, the team defined hypertension based on the limits established in 2017 by the American College of Cardiology and the American Heart Associationthat is, a pressure of 130 over 80 mmHg. The details of the study were published In an article In the magazine American Journal of Preventive Medicine. Activity mirror. As explained by the team responsible for the study, the increase in hypertension levels was a reflection of change in physical activity levels. The results supported what was observed in previous studies, that is, that exercise makes our blood pressure remain low. Check the recommendations. As the team explains, its results indicate that increasing exercise levels up to five hours per week could give positive results when reducing the risk that hypertension makes an appearance in the middle age. This is double that the two and a half hours recommended today in the guides considered by the team itself. In your study, They observed that 17.9% of the sample reached five hours of moderate exercise a week during its stage as young adults. These activity levels were related to a reduction in the subsequent risk of 18%hypertension. The reduction, they point out, was even greater in the case of those participants who maintained these activity levels up to 60 years. Different contexts, various results. The study was conducted in a sample of participants that covered different ethnic backgrounds. They observed differences between the Afro -descendant group and the white group, both between men and among women. Differences not only in the levels of hypertension, but also in how the levels of physical activity evolved as age progressed in the different groups studied.

The projects that played to be God during the twentieth century

On August 6, 1945, Two atomic bombs They razed the cities of Nagasaki and Hiroshima and, practically, put the end to World War II. It was a tragedy And, at the same time, a demonstration of strength. Demonstration of who would carry the baton in the new world order that had been created but, also, a demonstration of what was capable of doing nuclear energy. Aware of the military advantage that the atomic bomb, the armies of the most leading powers, They launched their developmentwith United States and the USSR at the head. The general atmosphere worldwide was fear and respect for technology that could cause a disaster never known until then. But, of course, it also served to give wings to the techno-optimists. Tecno-optimism is a current of thought that, In generaldefends that technological development and continuous improvement of current products will improve our life in the future, make it easier and increase our happiness. As I say, we talk about the master lines because This current of thought has different visions And, of course, detractors indicating that any development of a product or new invention can be used for malicious purposes. Noah Smith, journalist and extrabajador of Bloomberg, He puts as an example The use of drones as a gun to illustrate this last point of view. That techno-optimism lived a huge boom in the 50s and 60s. The cold war led humanity to an accelerated development that led people to spacethe First commercial opportunity of computersof Internet Oa to think of cars moved by nuclear energy. Why not? Nuclear energy for infinity car If any technology gained adherents among the techno-optimists of the 50s, nuclear energy was. In a document rescued by the International Atomic Energy Agency (OIEA) entitled 10 years of energy of nuclear origin It stands out that: “There was a period in which the fears that raised such a shortage became so deep that this was given to the commercial nucleotic energy its first great impulse. It was inevitable that the minds would turn to the new source of energy that had taken advantage of for war, as a means to compensate for the insufficiency of energy resources. When for the first time the nucleum energy became Easy about that means of obtaining cheap energy and in practically unlimited quantities, and among the fears that were sheltered on a shortage of energy of traditional origin and the hopes encrypted in an abundance of energy of nuclear origin, the latter prevailed, with an excess of optimism, until the end of 1957 “ As we said, despite the World War II Experiencenuclear energy won adepts rapidly and organizations such as the OIEA that defended its use for civil purposes, as a means of production of an electrical energy that was increasingly demanded. That idea that the nuclear led us to a “cheap energy and in practically unlimited amounts” promoted what we know as Atomic Ageor the era of atomic energy, born in the 40s. “The fact that we can release atomic energy inaugurates a new era in the understanding of the forces of nature by man. In the future, atomic energy can complement what comes from coal, oil and water, but that at the moment it cannot occur so that it can compete commercially with those sources. Before that happens, a long period of intense research must occur. It has never been the custom of the scientists of this country To the world scientific knowledge. The above words are from Harry S. TrumanPresident of the United States that gave the order to use the atomic bomb. The investigations showed that atomic energy could be used as a source of energy and, above all, as coal alternative and fossil fuelswhich were already seen as a finite source of energy and whose impact on people’s health was found first hand in the London of the 50s. At the point that nuclear energy could be a huge source of energy began to think applications for day to day. How to miniaturize technology to have, for example, appliances that will work with a nuclear battery that would last the entire product life cycle. Ford Nucleon model And, of course, the idea of ​​the car moved by nuclear energy came. The best known proposal is that of the Ford Nucleona prototype thought in 1958 that, of course, did not go from the model. The system was as simple as it was crazy: setting up a small nuclear reactor in the car. As? The rear, extraordinarily elongated would allow to shelter a small nuclear reactor. Inside, A uranium capsule It would work as a radioactive nucleus. As in any thermonuclear reactor, the uranium fission would cause a large amount of water vapor that would serve to move two turbines. One of them would start the wheels and the second would make all the electrical systems of the vehicle operate. Ford Seattle-ite XXI For some reason we do not know, Ford seemed that his plans could have some future and in 1962 they returned to the load. Then they presented the Ford Seattle-ite XXIa car that increased further the concept of nuclear car, to the point of having six wheels and body and interchangeable engines to pass from 60 hp to 400 hp. One option for day to day and another for long trips. The crazy concept was presented at the Century 21 exhibitionin Seattle, as an improved evolution of Nucleon. For example, it had been devised with six wheels because a double axis would serve to endure the weight of the small nuclear reactor in the rear. They even saved their backs pointing out that if one of the four wheels of the double axis were punctured the car would be able to continue with the rest. Guaranteed security and dynamism. Interestingly, the concept of this new car did have other inventions that we see in our current vehicles, such as a continuous tracking of the vehicle through GPS. Studebaker Packard … Read more

We have been trying to reinvent the wheel for years. It turns out that it was as simple as replacing it with pilates balls

I have always seemed curious the saying “We are not going to reinvent the wheel.” It is used when trying to develop a solution from scratch instead of taking advantage of an already proven and works well. And I say it seems curious because We have reinvented the wheel On many occasions, and we continue to do so. Two examples are wheels without air And, above all, the solutions for vehicles operating on land like Mars. Although circulars, its technology and design have nothing to do with the wheels we use daily. And, okay, I accept that, being circular, we are really changing the materials, not reinventing the object. But what if instead of making circular wheels … we made them spherical? Because that is precisely what the engineer and youtuber James Bruton has built: some omnidirectional wheels that solve current problems They have motorcycles and that would also be very interesting if they apply to vehicles such as cars and trucks. Let’s welcome the wheel II To reinvent the wheel, the system should not be just an improved version of the original. As I commented, the Antipinhazos wheels They are not a completely reinvention, but a technological improvement. What Bruton has achieved could be described as a reinvention (although he has side more than one attempt). The reason? In its motorcycle prototype of the future, we not only have the two balls that make contact with the ground, but a system of three rotary mechanisms for each wheel that are really applying the necessary force to move the balls and, therefore, the vehicle. More than the spheres, the key to the peculiar movement of this vehicle are systems that rotate in opposite directions and all the time balance each other to achieve movement. Each of these mechanisms is driven by an electric motor that transfers the power, but also introduced a self -evaluated system similar to that of a Segway. In this way, it is not necessary to rely on the floor with the legs when the vehicle stops, and it is not necessary to maintain the balance in a “manual” way. Its advantages? You can go back without boosting with your legs. It has lateral displacement. You can make diagonals and turn on your axis. For a parking lot, this is great. In the video it is very interesting to see that the noise it makes is minimal, that it reaches some speed and that the mechanisms that rotate the balls are working all the time to give speed to the vehicle and to maintain balance. Imperfect, but with potential Now, it is not perfect. In the video we can see that the youtuber has trouble going straight and There seems to be a quite pronounced difficulty curve both to go forward and to take a curve. In a road situation, it would be something really dangerous because, in addition, we do not have a conventional handlebar, but a bar that remains fixed and controls rotating the handle. There is also a time when it accelerates more of the account and the balls are shot. Wow, something like that would need your own driver’s license if applied to the real world, but if the problems were solved, it is a very interesting system for motorcycles due to automatic balance. For cars and trucks it would not be a bad idea either, since they could park much more simplely. Seeing this invention, the Audi of the movie ‘I, robot’ that has similar wheels and It was a real prototype. Also the Byd video parking in parallel Thanks to nailing the front wheels and making the rear turn slowly to “skid” until the car is aligned in the parking lot. Will we adopt wheel one day like these? Whatever happens, the truth is that it is interesting how we continue to find new ways to improve something that has implanted so many years.

toothpaste and snow

If a few weeks ago Sun Liang I would not have put a dentifric tube in the backpack before embarking on a trip between the Ao and Tai mountains may be dead today. Or at least he would remember his adventure for the icy riscos of northwest China as a more traumatic experience. After all, if Liang managed to survive in the middle of the mountain after getting lost, wandering between beasts and treacherous paths, it was because he endured how little he had at hand: the water he took from the river and snow and his toothpaste. Dental hygiene where appropriate served him for anything more than having healthy gums and a strong and shiny teeth. Mountain excursion. Sun Liang’s story have told her Jimu News and South China Morning Postbut it is so extraordinary, so rocambolesca, that it is not difficult to understand what is giving the return to the world And they have made echo of her media such as the Russian agency Tass. Logical. Not every day the story of a young adventurer who is lost track in a mountain in China is read and reappears after ten days, stating that he has basically survived swallowing toothpaste, snow and the water he took out of a river. Click on the image to go to Tweet. But … who is Sun Liang? A young Chinese mountaineer. And the young man is more than justified: he is only 18 years old. Despite his age and that he ensures that he developed his passion for hiking throughout the last year, in early February Liang decided to assume a draft challenge: he will travel alone 80 kilometers from the AO-TAI line, a route of around 170 km that connects the AO mountains and Taibaiin Shaanxi, northwest of the country. For two weeks he planned the expedition and invested Thousands of yuan In equipment. His adventure started on February 8. Alone, with no one to serve as a guide or support, the young man entered the mountain range Qinlinglocated in the province of Shaanxi, with an average altitude of around 2,500 meters. The trip soon twisted. Some versions They say that after two days he ran out of batteries (which among other things prevented him from communicating with his family), fell several times and fractured an arm. Othersthat on the fifth day of walking it rushed from a high height and in the fall lost the team with which it was oriented and its food. The accident left him unconscious one night and a doll broke. In desperate situations … Desperate measures, which is exactly what Liang sought. Only and incommunicado, the young man decided to walk down the river following a stream, took refuge after a large rock and an impromptu bed with what he had at hand was manufactured: dry grass and leaf litter. Another problem was how to feed in the middle of icy mountains, a challenge that Liang also threw a good dose of ingenuity. Especially since he did not want to risk eating moss or wild fungi that could poison him. Jimu News He recounts How to run out of food the young man survived with water from the river, melted snow and toothpaste. The first, the snow and the stream, allowed him to hydrate. The second, toothpaste, served as a sugar source, duck Straits Times. In any case it was not a pleasant experience. The dentifrum is not intended to serve as an appetizer and swallowed it nausea. A scare with a happy ending. The adventure ended well for Liang. More than a week after starting his adventure, while preparing a fire, he seemed to smell smoke and started screaming for help. Smell earned him as much as his obsession with dental hygiene. His voices alerted the rescue team that had come out in his search for the mountains. It was already February 17. And for the tranquility of Liang and his family the young man was finally able to return home. That the story will not end the worst forms does not mean that it had no consequences. The South China Morning Post remember That more than 30 people participated in the rescue operation and carried a cost of 80,000 yuan, around $ 11,000, for the young man’s family. That without having the implications that Liang’s recklessness could have. The Hongkonese newspaper recalls that since 2018 local authorities prohibit travelers from entering that area under the threat of sanctions. Why’s that? The area in which Liang decided to enter is especially dangerous. In fact, the AO-TAI line is one of the routes more demanding of the country for its changing climate, something that confirms a fact collected by the local press: over the last two decades more than 50 hikers have disappeared or deceased on the path by which Liang ended up wandering. “I felt terrified after the accident,” The young man confessed After the rescue, already safe at home. And in case someone wants to follow their steps, warns: “This area is not suitable for hiking. The wind was so strong that I could bare Remember Liang. “Moveing ​​the route is extremely difficult. In addition there are no good views and time changes abruptly.” Images | @Sofiadonnecke (Flickr) and The Humble Co.

It is so demanding that there have never been films that opt ​​for it

If you think that the Oscar They have too many categories, you don’t even know half: there are even more than we see. What happens is that one of them presents such high demands so that the films are nominated that it has always remained deserted. This year, in fact, some main film could opt for it, but one more year will be empty. And behind its existence there is a long history related to Music in cinema. Recycled musicals. The problem of this strange category dates back to the thirties, when the usual custom for the soundtracks of the films was the use not of exclusive original bands, but of previous musical compositions. We have all seen films of the thirties in which ‘The Lake of the Swans’ or other pieces of classical music, and Hollywood sounded realized that it was a problem when in 1938 ‘crazy for music’, a film without original compositions and whose credits did not even appear a composer, received an Oscar for the best soundtrack. Therefore, since 1939 the best original soundtrack was also rewarded, which won the mythical ‘Robin de los Forests’. The musical devastates. The situation changed again with new categories in 1942, when musicals became common currency in cinemas. Frank Churchill and Oliver Wallace won the best musical soundtrack for ‘Dumbo’, beating nine opponents. This category faced the best drama soundtrack, who won the great Bernard Herrmann for ‘The man who sold his soul’. For decades, soundtracks were rewarded according to these two distinctions, and suffering multiple variants (sometimes comedies and dramas were grouped in front of musicals, for example). Adaptations are over. Regardless of this distinction between musical and drama / comedy, in 1963 and until 1985 it went to a distinction between the best original soundtrack and the best adapted soundtrack, to reward the original compositions as it had been done in the thirties. In 1985, the adapted award was definitively dispensed with, and there was only one category, the best original soundtrack. The problem? Disney, always Disney. The Disney monster. Since 1989, with the premiere of ‘La Sernita’, Disney began razing, year after year, in the category of best soundtrack. Between 1989 and 1994, they won four times (in addition to that, ‘The Beauty and the Beast’, ‘Aladdin’ and ‘The Lion King’) and lost only two. To avoid Disney’s domination, in 1995 the category was divided into two: Best drama soundtrack and best comedy or musical soundtrack. The same was not missing: after change, Disney only won once again, with ‘Pocahontas’. The musicals, alone. Then, in 2000 a new distinction arrives: the academy decides that there are still two awards for original sound bands, but now we will have a better soundtrack and better original musical, an own category. To be part of that category, the film must include five original songs, and these must be “substantially reproduced, clearly audible and intelligible, and must contribute to the film’s argument. An arbitrary group of songs that are not essential for the argument will not be admitted.” Many films since 2000 have followed those requirements, but then … Why has the category remained unpublished? The durations, the quantities. To begin with, because the norms require a minimum minute for those soundtracks. For example, two musicals of 1999, ‘Tarzán’ and ‘South Park: larger, longer and without cuts’ had 45 -minute sound bands, insufficient according to the rules. And second and most important: at least ten films must be presented to the category so that it is open. An absolutely excessive amount for the moment that musicals currently live in the cinema. There are not enough musicals. And this is what has maintained the hidden category, despite successes (even within the Oscars) that show that gender lives good times, such as’LA LA LAND‘. We have had films like ‘Chicago’ (which would not have entered the category for proceeding with a theater musical) and this year, ‘WICKED‘. However, ten are too many: ‘The purple color‘,’Charm‘,’The great showman‘,’Vaiana‘… Great musical films, but you should add all of a decade to find enough tickets for one year in the category. According to They affirmed in Next Best Picturethe last time that amount was added was in 1963. Why follow. If the history of the Oscars is also the story of an endless list of dead categories (best dance direction, best black and white photograph …), Why is it officially active? Possibly because Hollywood does not want to miss the opportunity to reward a genre that is pure history of cinema. Maybe we would have to open something hand, allow type musicals to participate Jukebox as ‘Joker: Folie A Deux‘, Broadway adaptations such as’ Wicked’ or ‘Chicago’ or, finally, lower the minimum necessary nominated. The musicals deserve it. In Xataka | ‘The Brutalist’ is so long that it includes an intermediate of 15 minutes. And to the surprise of the director himself, people are delighted
