The Morgue of Paris organized “Open doors.” And caused tumults with thousands of daily visits

by

The bodies in the Paris deposit lie, motionless, completely naked except for small leather shrouds. Each one has died for a different cause, and all impute the reasons. Some have been stabbed in the belly. Another has drowned, he is swollen and his skin exhibits a obscene violet color. Another has been crushed by a heavy machine in one of the factories of the French city, increasingly industrialized and implacable. They all have something in common. They lie in almost vertical tables, which allow them to contemplate, on the other side of large windows, the thousands of Parisians who spend every day through the morgue. All bodies in the deposit can be contemplated by citizens. And it has become the favorite show of the pedestrians. In the mid -nineteenth century, walk in Paris to pass in front of the deposit and See the bodies It was the entertainment of fashion among citizens. Of course, there was an excuse: to help identify those who still had no name. But the morbid seized the population and went to see the exposed corpses became an entertainment that went far beyond public service, to the point that appeared in The guides of the time of the Parisian shows that the visitor should not be lost. Under the name of ‘The Museum of Death’, it was organized an entire industry around the facade of the body depositand it was easy to find actors, juggers and street artists asking for money in the surroundings of the great windows. He French playwright Leon Gozlan He described it like this: “You will see the drowned just like you go to other places to see the latest fashion.” And the very Emile Zola wrote: “The morgue is a show within the reach of all the pockets and that poor and rich passers -by may see free. The door is open, whoever wants to enter” Paris Danger At that time, Paris was a dangerous city (like all the great cities of Europe): crimes followed and occupied the first flat of the newspapers. And not only that: at this time when Industrialization grew by leaps and boundsthe mortality in the factories was very high, often the injured did not even have family in the city, but they came from rural areas and had arrived in Paris in search of money to feed their families, so that the bodies remained days in the deposit until they were claimed. These exhibitions in the morgue was like an extension of the black chronicle: the Parisians read in the newspaper about a crime or an accident and immediately could Expand the information going to see the bodies to the windows of the deposit. 40,000 people came to go to the dead daily (for getting an idea: Before your fireNotre-Dame received 30,000 a day). A true morbid show without a paragon in the history of the city. An example of what people came to see: on November 8, 1876, two packages containing the dismembered body of a woman were found in the Seine. The body was rebuilt, covered with a canvas and placed its head on it. A grotesque and brutal aging … that four days later of the crimes came to see more than 30,000 visitors, 40,000 on the 13th and 14th, the morgue records reached 68,250 entries. Almost a week after crimes, which makes a state of considerable decomposition. Finally, the closing of the show arrived: the Morgue of Paris closed the doors to the public in March 1907, when Criticisms won the unstoppable increase in morbid. Many newspapers complained, because their chronicles of which bodies were going to be exposed were among the most read of the daily rotations. The new century had just been born, and they were to come much more terrible shows. Although a little more modest.

We thought the tourist floors were the most profitable. Amancio Ortega has found something better: headquarters and shops

by

The rental market He has shot In recent years and with them the profitability that their owners They get them. Keeping this in mind, have you ever wondered how much must pay Inditex, Primark, Amazon or Apple for the rent of some of its offices or stores? Amancio Ortega, like homemade main From these companies has that answer: almost 1 billion a year together. Choose buildings without borrowing. In addition to the founder of Inditex, Amancio Ortega is the creator of one of the greater real estate empires in Spain: Pontegadea. The basis of his fortune remains his participation of 59.29% in Inditex, which allows him to access Milmillonarios annual dividends which strategically reinveys premium buildings distributed throughout the world. All this without borrowing with third parties. However, instead of focusing your business on the sale of these properties to obtain surplus value, your goal is to make constant profitability through rentals. Since its buildings have been specifically selected by Its strategic location In the main capitals of the world, the big firms are tail To rent some of its premises. Millionaire rentals. Thanks to this strategy, Pontegadea registered in 2024 income linked to real estate of 977 million euros, According to data to those who have had access Digital economy. This figure represents a 20% increase with respect to the 657 million euros that Ortega’s real estate registered in its 2023 accounts. This increase means that, for the first time, Pontegadea has exceeded the joint revenues from rents of its main rivals in Spain: Merlin Properties and Colonial. Something that It already foresaw That could happen for some years. They always buy with tenants. Such and as he published Expansionin addition to making a strategic selection of its buildings, Pontegadea has as a guideline buy buildings already occupied by solvent tenants. This has been demonstrated in all its operations, such as the logistics center of Baldonnell Business Park of Dublin From which Amazon operates, the Amazon headquarters in Seattleor the Venlo distribution centerfrom which it serves as the operations center of the DSV parcel company, one of the largest in the world. Thus, the new properties that Pontegadea incorporates in its portfolio generates income from the first minute and ensures something very valuable for a landlord: a tenant that pays promptly. Inditex also pays for rent: A Pontegadea. It is paradoxical, but some of the dividends that Pontegadea de Inditex receives are invested in premises that are then rented to the different brands of the group to install their stores or stores in them. That Pontegadea is the owner of the main premises of Inditex is a strategic advantage (in addition to a fine irony), since thus the textile can better deal with the variations in the price of the real estate market and not shoot their operational costs. OK To what is published For the economic one Expansionin 2024, Inditex paid 46 million euros for real estate rental to Pontegadea. That figure represents 18% more than the previous year, when the figure reached 39 million. In Xataka | Amancio Ortega: the billionaire who lives as one more neighbor.

27 kilometers under the sea to avoid fjords

by

Norway has underway A series of megaconstructions that aim to beat numerous records. It is not for less, because it is a country with a very particular geography in which certain types of infrastructure are necessary to opt for certain comforts. One of the most surprising is undoubtedly Rogfast, a four -lane submarine tunnel that will connect the districts of Randaberg and Bokn through 27 kilometers under the sea. This megaobra promises to revolutionize transport on the Norway west coast and drastically reduce travel times on one of the most traveled routes in the country. Fjords don’t make it easy. The E39 coastal road, which travels 1,100 kilometers from Trondheim to Kristiansand, is interrupted seven times by fjords that force Ferris. This turns a direct journey into a 21 -hour odyssey. Rogfast will eliminate one of these interruptions and will cut 11 hours of the total tripbenefiting millions of people who move to the cities of Stavanger and Bergen. Record figures. The tunnel will reach a maximum depth of 400 meters below sea level and extended 27 kilometers, officially becoming The longest road submarine tunnel in the world. It will surpass the current record, the Norwegian Lærdal tunnel of 24.5 kilometers, which crosses mountains but does not go under the sea. Turning Rogfast will take approximately 35 minutes and will have an underground roundabout at 250 meters deep to give access to Kvitsøy island. Image: Telegraph A technical and economical challenge. The works began in 2018 with an initial budget of about 1,838 million euros, although experts estimate that the total cost of modernizing the entire E39 could reach more than 40,000 million euros. The Norwegian government will finance 40% of the projectwhile the rest will recover through a toll of about 34 euros per use. The construction suffered several delays, especially during the pandemic, but maintains its scheduled completion date for 2033. Beyond travel cutting. Engineers have designed a special artistic project to combat monotony and anxiety that a tunnel can cause so extensive. The system promises to include dynamic lighting and decorative elements that will create a sensation of orientation and make the underground path more bearable. The idea is that drivers perceive travel time as shorter than it really is. Goodbye Ferris. Rogfast is part of a larger plan to completely eliminate the Ferris of the E39 and connect the entire Norway west coast with fixed infrastructure. Some sections will require “floating” tunnels anchored to the seabed due to the excessive depth of certain fjords. If the project is successful, Norway will have shown that it is possible to create a completely terrestrial coastal highway in one of the most challenging geographic territories in the world.

China is matching the West in a lot of technologies, but has already overcome something more crucial: research

by

Two years ago, in spring 2023, Springer Nature Editorial announced an expected Sorpasso. China had surpassed the United States in the Nature Indexan index created to measure the contribution to the scientific production of countries and institutions. It has been time for that and everything indicates that Chinese science, far from loosening the passage, has increased its distance from its main competitor. Solo leader. The last review of Nature Index Research Leadersthe “classification” based on the index prepared by the editorial responsible for the magazine Natureis A new test of the consolidation of Chinese institutions as a key piece in the global scientific research model. According to those responsible for the index, China achieved in 2024 an index of 32,122, a 17% increase Regarding the previous year, consolidating a first position that he achieved two years ago. From the company that elaborates the index it is also highlighted that the Asian country has eight institutions among the 10 most outstanding worldwide. Evaluating global science. After China and the United States, two European countries occupy the Third and fourth positionrespectively, Germany and the United Kingdom. Asian countries are also consolidated in the national “top 10”, with four countries represented (in addition to China, Japan, South Korea and India), matching the four Europeans in these head positions. The Chinese Academicia opens the List of institutions most outstanding scientists, followed by Harvard University and by the University of Science and Technology of China. The first Spanish institution that we can find in this ranking It is the Higher Council for Scientific Research, the CSIC. Nature Index. But what exactly is this index? He Nature Index It is an index Based on the contributions of scientists attached to various research institutions (whether public, private or companies). These contributions are measured through articles published in a sample of various high -impact scientific journals. Beyond Covid. In 2023 We pointed out That the leadership of Chinese science owed the work done by Chinese institutions in the fight against COVID, for example in the identification and sequencing of the virus some of its variants. However, we also pointed out that this advance also responded to a trend that had already been occurring since before the pandemic. After five years of the pandemic, the data seems to confirm the weight of this ascending trend beyond the situation of the pandemic. An ascent that is exclusive to this Asian giant but is also shared by other countries of the continent, such as South Korea and India, which saw increase in several percentage points (4.1% and 2% respectively) its contribution. This promotion of fact allowed South Korea to overcome Canada, standing in seventh position in this global classification of countries with the highest contribution to science. Tenth place. And what about Spain? The index of Nature Place Spain In thirteenth place in the global, sixth classification among the countries of Europe. Spanish science would be between Italian and Dutch, exactly the same as two years ago. The index in Spanish institutions. We pointed out at the beginning that the CSIC led the Spanish contribution to world science. The contribution of this public institution occupies a leading first place since its index (218) bends to the index of the second institution in the ranking National, the University of Barcelona (86), which is in position 245 in the ranking global. The third position at the national level is held by Barcelona Institute of Science and Technology (BIST).

It was not really a church

by

In Jaén they have been convinced for decades that the stones of a site of the old Ibero -Roman city of Cástulo (What is now the town of Linares) formed a Paleochristian church of the fourth century DC, they concluded it in the early 1990s its discoverers and thus continued to believe to this day applying good logic. After all, it is known that at that time there were Christians (and even bishops) in a cástulo, so it is not surprising that they wanted to have their own centers of worship, right? Now a group of archaeologists raises A different theory: And if what we have always seen as a primitive Christian temple really was something else? In a place in Jaén … Cástulo It was an ancient Iberian city that once acted as Capital of Oretania And today shows its ruins a few five kilometers from Linares. There, in the urban heart, in which archaeologists know as “area 1” rest the remains of a basilica -shaped building probably raised in The fourth century DC. We have known him for a long time thanks to the excavations made between 1985 and 1991 by a team that came to a clear conclusion: what they had before them were the remains of an old paleocristian temple of late antiquity. Why did they believe that? They had reasons. Although during their excavations they did not rescue any rest clearly associated with Christianity, archaeologists did know that at that time (towards the fourth century DC) Cástulo hosted a community of faithful. Even the presence of bishops is documented since at least the beginning of that century, something that makes it clear about the minutes of the Elvira council. Its characteristics, context and even the location of the temple inside the cástulo network seemed to support the theory that (effectively) was a church consecrated to Christ. “Taking all that into account, it seemed reasonable to think that the construction of the building was an example of the first Christian cult whose construction was motivated by the beginning of the rise of the Church in the second half of the fourth century DC,” Bautista Ceprián del Castillo, David Expósito and José Carlos Ortega, archaeologists who have published A study About the old temple in VeguetaThe Yearbook of the Faculty of Geography and History of the University of Las Palmas. Sobple matter? At all. That we have been believing that the old building of Jaén is a church of the second half of the fourth century DC does not mean that it is true, no matter how much this assumption seems to fit into history. This has been believed at least Ceprián, Expósito and Ortega, who relying on the excavations made in the place between 2011 and 2021 and especially the debris there have launched An interesting question: And if instead of a Roman church, the old temple, known as “building S”, was actually a synagogue maintained by a Jewish community established in the area around the fourth and v dc centuries New clues, New History. In their article the three archaeologists remember that 40 years ago they were not found in the area “Clear indications” They revealed that the temple was dedicated to Christian cult. What the new excavations have located are clues that point in another direction: “A small, interesting set of elements that refer to the culture and iconography of a Jewish nature.” These pieces, remains of ceramics and decorations, added to other characteristics, such as the location of the temple, is what leads Ceprián and his companions to suggest his theory. “There are certain singularities that alone would not dismant The study concludes After recognizing that “in a first analysis” the theory can be reached that the basilical absidal building was a Christian. What exactly did they find? During the excavations the researchers located three fragments of lucers decorated with the Menorá (Seven arms candelabro), a piece of Tégula in which the same symbol of Judaism is represented (although with five arms) and a revealing piece: remains of a bowl with an inscription in Hebrew that can only be read when placing it face down, which has taken archaeologists to think that it is a lid. What exactly does the text say? It is not easy to decipher it, although experts They slide which could be translated as ‘of forgiveness’, ‘Light of forgiveness’ or even ‘song to David’. Ceramics … and something else. All these pieces helped archaeologists to assemble their theory, but they are not the only arguments on which they support themselves. Another, fundamental, is the location of the building. The ancient temple rose in a separated place, little busy and close to the ruins of Roman hot springs, that the ecclesiastical hierarchy of the time perceived as “the last redoubt of pagan religion.” The reason? In public bathrooms, sculptures of ancient gods used to rise. “Many ecclesiastics would soon begin to consider the hot springs as a new idolatry center and a dangerous place for Christians for their more than probable demonic pollution,” Archaeologists reportwho remember that the rigid sexual moral of the Church already related nudity to “lust and sin.” “Tumulatio Ad Sanctos”. There are two data that further reinforce the theory embodied in the magazine Vegueta. The first is the configuration of the building itself, which as the experts recognize presents a structure that agrees with “the type of basilical absidal plants that will be developed from the fourth century DC in Jewish synagogues.” The second is that the most recent excavations have not revealed burials in the area, in the building or in its surroundings, something that clashes in principle with the Christian conception of the Tumulatio ad sancturesthe desire of the faithful of being buried near the remains of prominent martyrs and religious figures. In fact, where tombs are observed, it is in a nearby Christian baptistery. With what the absence of burials coincides, it is with the rabbinic pattern that states that the graves … Read more

Until recently they presumed how much they hired. Now the more they say goodbye, the more proud they feel

by

What times those in which technology companies hired as if there were no morning. The talent war affected even to countries like Spainwhere Amazon fought with a goal to achieve thousands of professionals. The CEO of all these companies celebrated the phenomenon and brought breast explaining that the pandemic had changed the rules of the game. They were proud to hire, but now they are proud otherwise. Checking. Charlie Scharf, CEO of Wells Fargo, has a doubtful record: to have managed to reduce its template for 20 quarters in a row. This manager has described the reduction of workers in this bank “as our ally.” In the last five years the total reduction amounts to 23%, They point In The Wall Street Journal. And there are more cases. Other companies also celebrate these workforce reductions, they indicate in WSJ. Loomis, a Swedish financial company, indicated that it has managed to grow despite recent layoffs, and Union Pacific, the railroad company, stressed that despite firing 3% of its workforce, it has achieved a record quarter. The Verizon CEO, Hans Vistberg, Indian In a recent conference with investors that in the field of workforce “we are being very, very good, and is constantly going down.” Or what is the same: he is very happy to fire people because as he highlighted “we are very efficient when managing our resources.” Lip-bu tan, CEO of Intel, advertisement that They would fire 15% of the workforceand his argument was that they needed to become a “faster, agile and vibrant” company. If you say goodbye it is because you are a great CEO. That seems to be the current perception of the technological industry, because while not having a long time to say goodbye to be a symptom of problems and a strategic withdrawal, it is now seen as a commitment to efficiency and the promising role of artificial intelligence. Elon Musk taught the way. The CEOS did not usually presume to fire people, but the thing changed When you bought Twitter. His first and controversial decision was dismiss approximately 75% of the workforce. The measure made the alarms jump and many wondered if the platform would subsist after that labor debacle. He has done it, and Musk, maximalist of efficiency, has always taken chest When talking about that measure. The efficiency argument. It is as if suddenly the industry had realized that it could make cuts punishing those Employees with lower productivity or looking for maximum efficiency in the template. More and more of the employee is talked about, and there Nvidia is one of the great prominent – clariously benefited by the AI boom. Now the argument between the bosses is defended that No one is irreplaceable. Prize to cut template. Zack Mikewa, of the firm Sloane & Co., explained in WSJ how to “be honest with the costs and the workforce is not only allowed, but is rewarded” by investors. The argument for dismissals in the past was the search for pure economic profitability, but now the excuse is the search for change and renewal, adaptation for that future complex that is presented to us. Downward hiring. Not only are there massive layoffs: there are companies that have also temporarily frozen hiring or slowed them for long periods. This is the case of Bank of America: his CEO, Brian Moynihan, explained to investors that during his mandate the template reduction has been remarkable. Since CEO was named in 2010, the workforce has gone from about 300,000 people to about 212,000, and as stressed “we have to continue working to reduce (that figure).” In Xataka | Microsoft has discovered that lining and saying goodbye to thousands of employees is compatible.

The summers are so short in Finland that he has accepted a guest to enjoy the beaches: kilos of poop

by

A few months ago, the Finnish nation was proclaimed for the eighth time the country Happy on the planet. Then we saw that nothing is perfect, because while it happened, the United States landed to prepare them next Battle for the Arctic. And between one thing and another, summer has reached its beaches. As always, it will not be very long, and this year is accompanied by an exorbitant amount of excrement. Brief and disputed. I told this week The New York Times. In a country where summer lasts just two months and the sun becomes a scarce good, every warm day is almost like a miracle. Helsinki, like the rest of the country, lives those weeks with intensity: crowded beaches, whole bicycle families and citizens anxious to take advantage of temperatures that in any other place would seem soft, but that exceed historical records here. However, in that space of evasion an unexpected intruder has appeared: the Barnaclas geeseRobust and gregarious birds that have colonized parks, avenues and, above all, the beaches of the capital. His MASIV PRESENCEA (more than 5,000 accounted for in the area last summer) has transformed the outdoor life into a constant surveillance exercise, where walkers must measure each step so as not to sink into excrements that accumulate in surprising quantities. The daily excrement. The problem, although an anecdotal in appearance, directly affects the enjoyment of a summer that the Finns consider sacred. On the beaches, before extending the towel you have to Check the groundVolley players pray not to land Bruces in a brown puddle, and parents watch with anguish that their young children do not confuse manure with sand or grass. The Times told That, in the parks, the lawn is upholstered with feces that are embedded in the soles, and in the central avenues the geese cross pedestrians with the same naturalness as the beatles very Beatles in Abbey Road. The figures illustrate the magnitude of the challenge: on some beaches, maintenance personnel collect more than 20 kg of excrement per daya volume that requires whole crews of seasonal workers, multiplied in the last decade. Failed innovations. For years, the Helsinki City Council has tested methods To contain the plague. They tried to mix the stool with the sand, but the water ended up contaminated. They used recordings of sea eagles to scare birds, but the geese got used to it soon. It was even studied to hire trained dogs, as other cities do, although they were too expensive and little available. The Great hope This summer was a machine designed by the maintenance team itself. A kind of sieve with wheels, similar to a manual corteped, which had to separate the feces from the sand. The problem? In practice it was Heavy and ineffective In humid soils, and ended up relegated to a warehouse. In the end, the most reliable resource remains the most rudimentary: shovel, gum gloves and infinite patience. Inevitable coexistence. The battle against geese, however, is limited by legislation and Finnish ethics: urban hunting or mass sacrifice is not allowed, such as in Canada or California, where transfers or culeing. In Helsinki, geese are not only a nuisance, but already part of the summer landscape, inserted in the urban imaginary and the daily routine of its inhabitants. In fact, the workers who collect the manure find a certain serenity in the repetitive task (although the smell persecutes them later). The reality is that, in a country where summer is too short to waste it, the Finns seem to accept this uncomfortable invasion as a price to pay to enjoy its beaches. With humor and stoicism, they have assumed that between the sun, water and sand there will always be a third guest: the omnipresent goose … and its inevitable trace.

China increasingly dominates technology on earth. There is a place where they are still far from Occiden

by

A recent report The New York Times He has evidenced the Chinese difficulty to compete with Spacex in the deployment of communications satellites. While Musk’s company already accumulates 8,000 Starlink satellitesthe two main Chinese networks just add 120 units in orbit. Why is it important. Low orbit satellites are strategic for autonomous cars, war with drones and military surveillance. China considers Starlink a direct threat and has planned two megaconstellations with 27,000 satellites between them. Qianfan, the constellation of low orbit satellites developed by China, anticipated having 650 operating satellites at the end of the year. Shanghai Spacesail Technologies, the company after the project, has only managed to put 90 in orbit since August. Guowang, an alternative born in 2020, is even worse: 34 satellites of the 13,000 planned for the next decade. The context. The Popular Chinese Liberation Army See Starlink as something “deeply integrated into the US military combat system”. It is not empty paranoia: this network is essential to coordinate drones in Ukraine and Spacex has government contracts for spying and missile monitoring. The background. China has not solved the key problem that Spacex solved years ago: reusable rockets. Chinese companies continue to wear single -use pitchers, which multiplies costs and reduces the frequency of launches. The Falcon 9 can reuse its first stage up to 20 times, greatly reducing the costs. After five hundred missionsit is still the reference. Chinese candidates –Long March 8R, Zhuque-3, Tianlong-3– accumulate failures and delays. Yes, but. China is negotiating Contracts with 30 countries to access Qianfan. He has already signed agreements in Brazil, Thailand, Malaysia and Kazakhstan, taking advantage of certain misgivings towards American technology dependence. The rhythm of Chinese launches accelerates: more than thirty missions in the first half, putting 150 satellites in orbit. But they need to multiply by five or six the rhythm to fulfill their international radio frequency commitments. In addition, there are some counterparts to your proposal: The decisive moment. Chinese megaconstellations must launch half of their satellites in five years after obtaining the frequencies, completing the deployment in seven. Not fulfilling could force them to reduce the size of the networks. Main loser? China dominates manufacturing, batteries, solar panels and traditional (non -advanced) semiconductors. But in sectors that require maximum risk assumption – Biotechnology, the space – the United States maintains a decisive advantage. Getting smaller in some scenarios, but maintains it. The business mentality that rewards rapid and cheap failures against guaranteed successes makes the difference between Spacex and its Chinese rivals.

Better not wait for the August 12 peak

by

If the Perseids are the Rain of fleeting stars More popular in the northern hemisphere is for something. They appear in full summer, when the skies are clear, the nights are more pleasant and many are on vacation. But this year they have a problem. Luna almost full at the worst moment. In 2025, the Perseidas Activity Peak The night will take place from August 12 to 13. As every year, it is the moment in which we should see the most meteor. But this time, the Perseids will share the stage with an guest star that nobody wants on an astronomical observation night: a large and brilliant moon. According to the August lunar calendar, the full moon will come on day 9. This means that for the night of 12, our satellite It will be in the diminishing phase gibosa90%illuminated. Although we move away from the cities, the natural light pollution of the moon will complicate the visibility of the weakest meteors. Only the most spectacular and bright cars will stand out in heaven. When to see the Perseids. According to him National Geographic Institutethe moment with the greatest abundance of meteoros will occur on August 12 just after the sunset, around 22:00. The moon will appear on the horizon approximately an hour later, so we will have a very scarce margin to accustom the eyes to the dark and enjoy the hunt for perseiders. Our advice to have a more relaxed and lasting experience: not wait until then. The Perseids or tears of San Lorenzo They are active from July 17 to August 24, so this weekend we can see them burning in the night sky. And the growing moon will be hidden soon through the west, leaving a night with a perfect dark sky for observation. How to locate them in heaven. Whether you decide to get ahead and if you prefer to wait, the first thing is get away from the city’s lights: Go to a beach, the field or the mountain, especially if it is “in the shadow” of the moon. The less light pollutionmore stars and persistent you can see. The most popular meteor rain of the summer owes its name to the constellation of Perseus, but the most effective way to see them is not to look for the constellation on the map, but to stare at the darkest part of the sky (care with the neck, better to be lying) because they can appear anywhere, provided there are no clouds, and the greatest possible field of vision will be good for you. Your eyes need between 15 and 20 minutes to adapt to total darkness, so it is best to avoid using the mobile. Anyway, perseiders are so fast that it is difficult to take pictures. A time-lapse or video are safer options. For the same reason, it is not worth using telescopes or prismatic.

cut mountains

by

The tunnels have saved us from surroundings to mountains and rock surfaces for decades. However, it is not the only technique to shorten time and develop new roads that connect cities with each other. In this aspect, it is worth telling how China once again demonstrates its ability to transform the landscape with a technique that seems taken from a science fiction film: literally cut mountains To build roads. Explosives, giant excavators and a millimeter planning is necessary to divide rock formations of hundreds of meters high. How the technique works. After A geological study Exhaustive to determine the composition of the mountain and plan the cuts so that they do not compromise the stability of the land, engineers use controlled explosives to create the first fractures, followed by specialized heavy machinery that can excavate tens of meters deep per day. The remaining walls are stabilized with metal meshes, projected concrete and drainage systems to avoid landslides. The final result is A clean step through the mountainwith vertical walls up to 200 meters high that seems that someone with a giant knife has crossed them. A technique in multiple regions of China. These ‘cut walls’ can be seen mainly in The mountainous provinces of GuizhouYunnan and Sichuan, where the karst terrain and the complicated rock formations made the construction of traditional tunnels impracticable. Projects as prominent as the Guiyang-Qianxi highway or the Taihang mountain pass have turned hours of hours into minutes. It has also been used in the construction of the High Speed Railroad that connects Beijing with Guangzhou, where several sections go through literally games in half. Click the image to watch the video Why not tunnels are used. The decision to cut instead of drilling usually comes Due to technical criteria and specific economics. In land with high concentration of groundwater or unstable rock formations, building tunnels can be more expensive and risky than direct cut. In addition, the maintenance of an open step is considerably simpler than that of a tunnel, which requires constant ventilation, lighting and drainage systems. In low -rise mountains, the cut also allows the greater proliferation of heavy vehicles, especially in an economy that depends so much on the transport of road goods. Beyond China. Although China has perfected and popularized this technique, it is not the only country that uses it. Norway uses similar methods in its fjords, where the characteristics of the land make the cut more viable than drilling (although in this country we also have spectacular projects of tunnels under construction such as Rogfast). In the United States, Cumberland Gap’s pass in the Apalaches was created by cutting techniques, although on a smaller scale. However, no country matches the ambition and scale of Chinese projects, which have become an art the mountain cut. Environmental impact. Although the benefits of using this technique are evident, especially in the aspect of econic development and its effectiveness to connect remote regions, this technique also generates a certain debate around environmental impact. And it is that this type of constructions can end up destroying local ecosystems, altering natural drainage patterns or fragmenting wildlife habitats, not to mention the amount of dust and noise during its construction that can generate millions of tons in waste. It can also be said that it is not the most used technique, since the tunnels remain the preference except exceptional cases.
