allow retirees to continue working

In September 2023, Europe turned in unison to Germany. What was normally one of the most solid economies in the euro zone was sounding the alarm: adding greater life expectancy to a demographic scenario of an inverted pyramid and an inflationary context left a very unpromising outlook for who are going to retire soon. In fact, the system was bringing retirees back to look for work to supplement pensions. Two years later things have not improved, so the government has normalized them. A structural turn. The Government of Friedrich Merz has put a clear and pragmatic proposal on the table: allowing retirees who decide to continue working receive up to 2,000 euros per month tax-free, a measure (the so-called “active pension plan”) designed to tackle the growing labor shortage that grips Europe’s largest economy. The initiative is part of the package of reforms that the Executive has sold as his “autumn of reforms” and, according to the legislative draft in hands of the Financial Timeswill come into force on January 1. The coalition with the Social Democrats is preparing to approve it with the argument of retaining experience and knowledge in companies and increasing the employment rate in a country that faces one of the most severe demographic transitions on the continent. What is offered and what is maintained. The measure exempts taxes up to 2,000 euros per month of additional labor income for retired people, but it does not eliminate contributions: employees and employers will continue to pay social contributions on those salaries, which (according to the Executive) will help strengthen healthcare and pension finances while improving the liquidity of companies with senior experience. The already existing advantages for those who opt for early retirement (the legal age It’s still 67 years oldwith incentives to retire at 63). The change is intended, rather, to offer a tax incentive so that those who can and want to prolong their working life do so. Public cost and projections. The Government itself estimates that the renunciation of collecting taxes for this incentive will cost around 890 million euros per year since its entry into force, a figure that some institutes consider optimistic: the IW Institute calculates a higher annual cost close to 1.4 billion and places the potential universe of beneficiaries at around 340,000 people. Economists such as Holger Schmieding warn, however, that the net impact could turn positive in two or three years if the increase in economic activity and contributions compensates for the initial tax loss, in addition to the possible “psychological effect” of socially valuing the contribution of the elderly. International lessons. The Government looks, among other examplesto Greece: when Athens allowed retirees keep their pension full and were additionally taxed at a reduced rate (10%) for their labor income, retired workers went from 35,000 in 2023 to more than 250,000 in September of the following year, a jump that illustrates the power of tax incentives to mobilize labor supply in older groups. That experience is used in Berlin as a sign that politics can workalthough the scale, work structures and employment cultures differ. Consequences in the labor market. The gesture aims to attack several structural symptoms: Germany today records some of the average working hours shortest in the OECD and marked growth from part-time work (which now reaches 30% of the workforce, more than double what it was at the beginning of the nineties). The policy aims to both increase effective hours and retain human capital that would otherwise escape companies. Keep staff on staff senior can help reduce bottlenecks in sectors with a shortage of qualifications and facilitate the transfer of know-how, but it also poses the challenge of adapting positions, ergonomics and internal policies to an older workforce. Political and economic risks. The main risk it’s double: On the one hand, the measure may penalize young people and employees in early career stages if companies choose to retain positions with cheaper payrolls and more experienced workers. On the other hand, the Executive’s fiscal estimate could fall short if membership is high, putting pressure on public accounts at a time when the cost of social systems is already putting pressure on the budget. Besides, recalled the Times that there is a dimension of equity and public narrative: promoting people to work longer is politically sensitive when there are sectors with precarious employment or stagnant wages. Pragmatism with doubts. Ultimately, the plan to allow 2,000 euros tax free to working retirees is, in essence, a pragmatic and technocratic response to a demographic shock and the lack of skilled labor: seeks to monetize experience, sustain contributions and gain economic muscle without resorting solely to mass immigration or abrupt increases in working hours. Yet, your success will depend the magnitude of the accession, how it is combined with other labor policies (training, conciliation, redistribution of part-time employment) and the honesty of the fiscal projections: if the reception is high, the cost could approach the most pessimistic figures, and if it is moderate, the initiative can become a respectable exercise in institutional adjustment that contributes to lengthening the active life of many and partially mitigating the bill of aging. An unknown scenario that Japan also considers.

Spain has an antidote to mental and emotional exhaustion: the nap

In Spain, the tradition of the siesta has long been a cultural habit. However, today science claims it as a valuable resource to combat mental and emotional exhaustion. Different studies show that a well-planned nap not only helps you regain energy, but also improves cognitive functions and mood, something especially useful in times when stress and fatigue are the order of the day. Therefore, napping is an effective strategy to maintain active and balanced mind throughout the day. A mental reset called a nap The importance of the nap lies in its ability to refresh the brain and body, allowing people to face their daily tasks with better spirits and concentration, as highlighted a study from the University of Coruña. A quality nap increases energy, alertness and relaxation after rest. Improves concentration, memory and logical reasoning, promoting better performance in activities that require attention and mental speed. Besides, helps stabilize moodreduces impulsivity and makes it easier to calmly handle the frustrating tasks that often appear during the day. The scientific evidence indicate that even very short naps of just six minutes can be effective in improving sleep. processing of ideaswhile longer naps help consolidate long-term memories. For the nap to be effective, its ideal duration this between 15 and 30 minutesenough time for the brain to recover its capacity, but without entering phases of deep sleep that could cause drowsiness when waking up. Likewise, the best time to take a nap is between 2:00 p.m. and 3:00 p.m., a time that coincides with a natural drop in energy during the day. If the nap lasts too long or takes place after three in the afternoon, it can negatively affect nighttime sleep, generating insomnia or a phenomenon known as “sleep inertia“, which consists of a feeling of drowsiness and difficulty reactivating after rest. Additionally, if naps become frequent and long without any noticeable improvement in performance when you wake up, it could be indicative of a sleep disorder underlying that should be evaluated by a professional. The nap is a break, not a substitute It is essential to clarify that the nap should in no case replace the need to sleep between seven and nine hours a nightsince this night rest is essential to maintain good general health and ensure efficient recovery, something that is only achieved when the brain reaches certain phases of sleep. “Sleeping well is much more than the time you spend in bed. The first is the number of hours you sleep. The second is the quality of sleep: having restful, uninterrupted sleep. The last is a regular sleep schedule,” assures Dr. Marishka Brown, sleep expert at the National Institutes of Health (NIH) Not all people experience the same benefits of nap; The effects may vary depending on individual factors such as lifestyle and health. When you rely too much on long naps to compensate for fatigue, could be a symptom of health problems that require medical attention. In fact, some studies indicate that prolonged naps they associate in certain cases with metabolic problems such as obesity, although a direct causality has not been confirmed, but rather other factors related to lifestyle intervene.

almost a million employees for a colossal project

BYD surpassed 968,900 employees by the end of 2024, more than Tesla, Toyota, Ford, BMW and Renault combined. It is a figure that would be absurd for any traditional automaker, but it has a simple explanation: BYD is not just an automaker. Methodological note: This figure includes the entire BYD Group, not just BYD Auto. Unlike manufacturers that clearly separate their divisions, BYD operates as an integrated ecosystem where the majority of employees are directly or indirectly linked to the automotive business. The company does not publish a breakdown by division. Why is it important. The Chinese company has built the largest vertical integration ecosystem in the automotive industry worldwide. Tesla, for example, buys batteries from Panasonic and chips from third parties, but BYD manufactures absolutely everything in-house. Its business model covers four complete industrial sectors: The automobile division is only the most visible, but also manufactures electronics for Apple. And it produces batteries as the second largest manufacturer in the world. It also develops components from semiconductors to heat pumps. More than 110,000 of its employees work exclusively for Apple’s supply chain, assembling 30% of its iPhones and iPads. The BYD figure, as we said at the beginning, is for the entire BYD group, not just BYD Auto. Other manufacturers have their own nuances: Volkswagen’s 656,134 employees only include the automotive group (Volkswagen, Audi, Porsche, Skoda, etc.), and not large divisions such as finance. However, it does include small divisions of components, such as engines or transmissions. The 389,144 employees of Toyota are only from Toyota Motor Corporation, it does not include Industries (components, textiles, forklifts, etc.), Aisin (transmissions, brakes), Denso (electronic components) or Boshoku (interiors). The complete Toyota ecosystem would be about 800,000 employees. The context. BYD applies a long vertical integration: They internally produce batteries, semiconductors, software, heat pumps, electric motors, control systems, fast charging and structural elements. This strategy allows them total quality control, cost reduction and speed of innovation superior to rivals that depend on external suppliers. Its eight factories in China have tens of thousands of workers. Each one. The Zhengzhou plant has 60,000 employees and plans to hire 20,000 more. Furthermore, they have created authentic “industrial cities“with housing, services, commercial establishments and sports facilities for workers. In figures. The numbers justify the strategy: Employee growth: 37.73% in 2024 (265,400 new workers). R&D personnel: 110,000 engineers, the largest in the automotive world. Cars sold: 4.27 million units in 2024. Go deeper. The contrast with its competitors is striking: Tesla laid off 15,000 employees in 2024. Ford plans to eliminate 4,000 jobs in Europe. Renault is considering laying off 3,000. BYD continues to increase its workforce. However, direct comparisons are complex due to the different business structures mentioned above. They have hired almost 50,000 recent college graduates in two years in China. In the rest of the world they are also advancing: they are building factories in Hungary (2,000 jobs), Mexico (10,000 planned jobs), Brazil, Thailand and Indonesia. Its expansion model, as we have already seen in Spaingoes through the total localization of the production chain. The question is whether this model is sustainable in the face of increasing automation. In fact, Tesla has clearly shown its approach to robotization, but BYD seems to prioritize the human factor for the moment. At least for its model of total control of the productive ecosystem.

the oldest experiment in the world

It was 1832 and John Bennet Lawes I was just 17 years old, had a huge estate in the heart of Hertfordshire and lots of free time. He had just been kicked out of Oxford and had returned to the mansion he inherited from his father a decade earlier. Now he just had to see what he did with his life. He didn’t know it, but he was about to launch the oldest running experiment in history: the Broadbalk Experiment. What if we plant four herbs? This is how Lawes began, growing medicinal plants on the farm and testing the effects of various fertilizers in a handful of pots. Things went well and, a couple of years later, the experiments expanded to field crops. Young John Bennet’s intention was simple: to make farmers no longer have to rely on animals to produce fertilizers. He got it. Wow he did it. In 1842, he patented a phosphate-based fertilizer that revolutionized the world of agriculture and ushered in the era of industrial fertilizers. It was made of gold, of course. But that is not what interests us today. What interests us is that from the autumn of 1843 and to study the long-term effects of different fertilizers and manures on the yield of winter wheat and soil fertility, he began planting wheat in Rothamsted. What does it consist of? The first harvest was in 1844 and, since then, strips of wheat have been grown with different fertilizer treatments throughout the field. That means some strips have received the same amount of fertilizer for more than 160 years. That doesn’t mean there haven’t been changes, of course. The Broadbalk experiment is a living thing and has changed over time to address new scientific problems (such as the introduction of different varieties of wheat or the application of new breeding approaches). It has been a great success, too. Not only did it allow (and allows) fine-tune with unprecedented accuracy the amount, frequency or type of fertilizer we should use; Broadback has generated a large amount of data and samples (of grain, straw and soil) that are used by scientists around the world for long-term studies on environmental impact and agricultural sustainability. It is not something trivial. The argument about not knowing what the long-term impact of things will be is not only reasonable, it’s a good one. This experiment has allowed us to dispel all the doubts we had regarding one of the most important technologies in the world: which has allowed that we are more than eight billion people in the world.

With AI, Microsoft has once again insisted that we talk to our computer: experience says that we don’t feel like it

You get up in the morning, go to work and sit in front of the computer, but the first thing you do is not pick up the mouse and keyboard, but say “Hey, Copilot”. Can you imagine it? Me neither, completely, but that is Microsoft’s clear obsession: to get us to talk to our PC instead of using the usual peripherals. That futuristic vision is striking, but it faces several enormous challenges. what memories. The thing about Microsoft and other technology companies with their intention for us to talk to machines goes back a long way. The first generation of voice assistants precisely pursued that goal. There we saw how Alexa, Google Assistant and of course Cortana tried to make us talk much more with our devices. We were not prepared to talk to machines. Its success was rather limited, and even Nadella himself admitted in 2023 that, for example, those “smart” speakers They were “dumber than a stone”. In Xataka Voice assistants and the fight to gain our trust Cortana tried. The Redmond company certainly tried to make Cortana successful. It offered it on both Windows 10 and on Android and iOS…and even the sadly defunct Windows Phone. Over time the company realized that that assistant was not a good fit, and was killing him little by little. The launch of ChatGPT was used by Microsoft to raise your new assistant powered by AI and definitely kill to his first assistant: Copilot wants to be what Cortana could never be. Who asked for this? With that “Hey, Copilot” the same thing is happening as with Cortana: did someone ask Microsoft to integrate a voice assistant into Windows? The voice assistants of that first generation were relegated to residual use, and Amazon suffered this problem firsthand. He bet billions of dollars that Echos would become devices we wouldn’t stop talking about, but most people I just used them to set timers and music. AI promises to go much further. But in spring 2024 we live in a hopeful moment for this type of technology. OpenAI launched GPT-4o and demonstrated that natural conversations with a mobile phone were not only possible, but also They were very powerful. AI could be ours confidant and companion -with controversy included— or our private teacherand as others later wanted to demonstrate, it could also do things for us just by talking to her. Let them tell you to the vibe coders. But we still have a hard time talking to the PC. Since then it certainly seems that we have become a little more accustomed to talking with our smartphone, but things seem to be different on the PC. The statistics reflect that 77% of young people use their voice on their smartphone, while only 38% of them do so on the PC. “But everyone on the PC listens to me”. There is also a sociological component in this use of voice on the PC. The mobile phone is more intimate and personal, while the PC is often used in a static setting in which there are people around who can capture what we say. Furthermore, in the physical context, the unspoken rules of coexistence—do not disturb, do not invade others’ acoustic space—outweigh the promise of comfort. And then there is distrust. Microsoft is not helped by its recent history, especially with Recall, that option that seemed really striking and ingenious but ended up being delayed to generate a great controversy regarding privacy. The launch of the new Windows 11 options, with “Hey, Copilot” as the main protagonist, does not seem to have been received with too much enthusiasm, and the tone, for example, of the comments from this long thread It is skepticism. Rivals focus on mobile phones and speakers, not the PC. The truth is that the adoption of voice as a way to interact with our devices does not seem to be particularly viral. The erratic launch of Alexa+ does not seem to be providing great advantages, Apple continues to make itself wait with its renewed version of Siri, and only Google has taken a step forward with Geminialthough not clearly on the desktop. Talking to machines works, but not as much on the PC as on the mobile. {“videoId”:”x9jvzns”,”autoplay”:false,”title”:”Project Astra Exploring the Capabilities of a Universal AI Assistant”, “tag”:”Project Astra”, “duration”:”116″} A triumph for accessibility. Where there is a clear use scenario for this technology is in the area of ​​accessibility. For users with reduced mobility, the ability to dictate or control the device with their voice can be transformative. This need is concrete and well defined, however: it does not justify a general redesign of the interaction or a marketing campaign that tries to get us all to talk to the computer. The voice should solve things, not be a fair trick. Microsoft’s real challenge is not technical — the technology is there — but human. The company must convince people that talking to the PC makes sense. To do this, it must address three fronts: privacy, the social context—that you don’t mind talking to your PC—and of course, that said interaction has practical use and works. For example, they come in there Copilot Actionswho will have to demonstrate – like everything else – that Microft is on the right path here. Otherwise, “Hey, Copilot” could become the new Cortana.

30% of depressions do not respond to pills or psychotherapy. A psychiatrist’s idea: treat them with ultrasounds

Depression is a truly complex disorder, which in 30% of cases do not respond to treatment conventional. Neither pharmacotherapy nor psychotherapynor the transcranial magnetic stimulation (used to treat OCD) appear to offer lasting relief to those who become trapped in the more resistant states of the disease. And although at first they can be ‘given up as lost’, the Argentine psychiatrist Salvador Guinjoan He is already working on another avenue of treatment. The idea. The psychiatrist, researcher Laureate Institute for Brain Research from Oklahoma, is working on an alternative that uses more physics than psychiatry for these patients who a priori had no other type of solution. This is based on the low intensity focused ultrasound, what is known as LIFU (Low-Intensity Focused Ultrasound). During the recent Conference on Updates on Neuromodulation held in Seville by the Spanish Society of Clinical Psychiatry, Guinjoan explained that the objective is quite ambitious: to modify the electrical activity of the brain circuits involved in psychiatric symptoms without the need to open the skull or implant an electrode as he explained. in an interview to El País. What is LIFU. This technology uses mechanical energy instead of electrical or chemical energy. Its transducer generates ultrasonic waves that are capable of passing through the skull and concentrating the energy at a very specific point in the brain, subtly modulating the mechanosensitive ion channels of the neurons. In practice, this alters neural communication in regions that are involved in emotion, motivation, or decision-making. But the important thing in this case is that unlike traditional deep stimulation (DBS), which requires surgery and permanent implants, LIFU allows completely reversible interventions with high anatomical precision. According to Guinjoan, the method opens the possibility of observing, for the first time, causal relationships between a specific brain circuit and a clinical symptom: “If modifying a circuit changes the symptom, we can begin to understand the cause,” he points out. The bibliography supports it in these cases, since previous research, such as those carried out in the Massachusetts General Hospital and published in Nature Neuroscience (2024), had already shown how LIFU can influence deep regions such as the amygdala or thalamus without visible tissue damage. Now, the challenge is to transfer that precision to the psychiatric field. Key points. Guinjoan and his team focus their trials on two key markers of resistant depression: anhedonia (inability to experience pleasure) and the persistence of negative thoughts. Both phenomena seem to be related to connection circuits between the prefrontal cortex and the basal ganglia. And it is precisely in this circuit where the psychiatrist wants to intervene with LIFU. The researcher suggests that modulating the subcircuits that connect the prefrontal cortex and the basal ganglia with ultrasound can alleviate these characteristic symptoms without resorting to surgical interventions and perhaps without more medication in the future. And although at the moment there is still a long way to go, pilot studies in the United States point to sustained symptomatic improvements after several sessions, with mild side effects such as temporary headaches. The ethics. The ability to literally reprogram the brain without invading it opens up questions that go beyond medicine. Guinjoan agrees with neuroscientist Rafael Yuste, promoter of the neurorightsin which it is urgent to regulate the non-therapeutic use of these technologies. Although the border between treating a disease and enhancing mental performance is increasingly blurred. Unlike other home neuromodulation tools, such as transcranial electrical stimulation (tDCS) devices that They are already sold for personal useLIFU requires high-precision neuronavigators and a specialized clinical environment. Guinjoan does not believe that it will become a domestic technology, but he does imagine a future where each patient receives a personalized neuromodulation treatment, adjusted to their specific neural map. The future. If ongoing trials confirm efficacy, focused ultrasound could be incorporated in the next decade into the arsenal we have in the treatment of resistant depression, anxiety or even schizophrenia. All this without having to enter an operating room. Something that could also represent a new leap in psychiatry as we know it and a paradigm shift in the therapeutic approach to this type of pathology.

There is more demand than leaves, more fashion than ceremony

the book The wind through the pinesby Malena Higashi talk about a lesson that seems forgotten: relearning to breathe. In its pages, the tea ceremony—the chado, or “tea path”—is a metaphor for slowness, for respect, for what the Japanese summarize in four words: wa, kei, sei, jaku (harmony, respect, purity, tranquility). That ancestral stillness contrasts with the present. In just a decade, matcha—that green powder that for centuries was ground in temples and served in silence— has become in a global phenomenon. Coffee shops in New York, Paris or Madrid offer it with vanilla, banana or oat milk. There are numerous videos on social networks of people drinking matcha with hundreds of millions of views. However, behind that vibrant color and perfect foam there is something broken: “The matcha market is cracking under pressure.” From the temple to the algorithm. For four centuries, matcha was reserved for formal ceremonies and high tea craftsmanship. Today, as explained in The New York Times: “Harmony has been replaced by discord, respect by unscrupulousness, and purity by fraud.” Historical companies such as Marukyu Koyamaen, founded in 1704, They fight fakes of their tea on Amazon or Facebook Marketplace. Some sellers offer yellowish powder—ordinary ground tea—in fancy packaging, while others market an “imperial grade” or “barista grade” that do not exist in the Japanese classification. The global boom has created a demand that Japan cannot satisfy. “It’s like the Old West,” points out the merchant Sebastian Beckwith, faced with a deregulated market where matcha has become a label rather than a quality. The numbers in a bubble. The data does not deceive anyone. In just one year, Japanese exports of green tea powder have grown by 75%reaching almost 27,000 million yen, about 165 million euros. But enthusiasm has its price: a kilo of tencha leaves – the base of matcha – already exceeds 14,000 yen (about 85 euros), almost triple what it was a year ago. It is the highest price in memory and a clear sign that global demand is pushing the limits of tradition. Japan today exports more than half of the matcha that it produces, but that has not resolved the imbalance. In Uji, the birthplace of green tea, the shops limit the sale to one can per customer and farmers reject new orders until the next harvest. Jiro Katahira, a producer from Shizuoka, says to have received requests from all over the world: “Even from Benin. But I can’t mass produce. You can’t speed up a process that takes years.” For its part, in Los Angeles, the crisis is felt differently. At the Kettl Tea bar, only four of the 25 varieties on the menu remain. “There is nothing more to buy”, confessed its founderZach Mangan. The result is a fractured market: large wholesalers like Marukyu Koyamaen cannot cope, and small producers struggle to maintain quality while prices rise and there is a lack of young hands in the fields. An unsustainable boom. Matcha cannot be grown like corn or coffee. The tencha leaves They need weeks of shade before being collected, steamed and slowly ground between granite stones. Five years can pass from sowing to the first harvest, and many Japanese farmers – with an average age of 69 – lack generational change. The Japanese government has launched subsidies to modernize factories and increase mechanization, but that, experts warnyou could sacrifice the artisanal quality that distinguishes Japanese matcha. Meanwhile, China, Korea and Australia are taking advantage of the vacuum. According to FTChinese producers are introducing matchas “dyed” with chlorophyll to achieve a brighter green. “If everything becomes matcha, nothing will be,” a merchant tells the newspaper. The loss of value: from ceremony to latte. In the chadoeach movement has a meaning. In the global market, everything is measured by likes. “Using first-harvest matcha in a latte is like using Burgundy wine to make sangria,” Zach Mangan denouncedfounder of Kettl. The big chains have turned it into a trendy flavor. starbucks launched matcha protein drinks with banana cream; Blank Street Coffee removed the word “Coffee” of his name and embraced the “matchacore” aesthetic; the influencers they mix matcha with collagen. In this new context, matcha is no longer a drink, but a texture, a color, a mood. Master Rie Takeda, founder of the Chazen tea room, prefers to see it from an optimistic perspective: “Yes, there are concerns, but if this trend sparks interest in the tea ceremony, welcome. Our challenge is to share the essence of tea without losing its spirit.” Others, like Shihori Suzuki, warn of the risk of confusing spirituality with aesthetics: “Matcha has become a mass product, alien to the ceremony. If it becomes just a business, we will lose quality and meaning.” What is at stake. The rise of matcha not only threatens to deplete the fields, but to disfigure a cultural identity that took centuries to build. Farmers, like Katahira, they see it with ambivalence: Thanks to the boom they have paid off debts, but many feel that the spirit of tea is diluted between influencers, baristas and designer packaging. “Those who rush to produce don’t think about tradition. They only think about lattes,” he says. However, other people see it as a phenomenon that could save the tradition: more visitors flock to authentic tea rooms, seeking the calm that social media does not offer. After the pandemic, says Atsuko Morifounder of Camellia Tea Ceremony in Kyoto: “Visitors don’t just want to taste matcha, they want to understand it. They value its sense of presence and attention.” But that balance is fragile. The same tea that calms is also exhausting those who grow it. Producers face a paradox: commercial success can destroy what made it valuable. Return to the dô? Matcha was born to stop time, not speed it up. The tea master Sen no Rikyū, in the 16th century, said to serve a perfect cup was an act of harmony between host and guest. Today, that harmony is sought between saturated markets, influencers … Read more

A hero without a cape recorded the same shot for a year. Along the way he left the flat earthers without arguments

Intrigued by the phenomenon, Eratosthenes decided make an observation in Alexandria, located about 800 kilometers north of Siena. There, on the same day and at the same time, he noticed that a vertical stick did cast a definite shadow. The discrepancy led him to a fundamental question: how was it possible that in one place there was no shadow and in another there was, at the same time? Eratosthenes deduced that the only explanation was that the earth’s surface was curved. A lot of time has passed since then, but the flat earthers are still among us. The home experiment. For centuries, the idea of ​​a flat Earth has outlived telescopes, satellites and lunar missions. Despite the overwhelming evidence, from the images taken from space and the established physical principles from Aristotleflat earthers have continued searching for the edge of the planet, organizing expeditions to Antarctica or navigations to the supposed “end of the world” that invariably end with the same discovery: that the edge does not exist. Be that as it may, an anonymous Reddit user has dismantled once again his entire creed without leaving home. Armed only with a security camera, the shadow of his garage and the patience of an entire year, he managed to record a test as simple as it was incontestable: the movement of the Sun drawing a figure of eight perfect on the ground. The footprint of the Sun. Between March 2024 and March 2025, this user (under the alias RedditorofReddit07) marked daily, at the same time, the position of the end of a shadow cast by a corner of his garage. After twelve months, the yellow dots traced on the cement an asymmetric curve in the form of infinity: an analemma. This phenomenon, documented by astronomers for centuriesis the direct result of the 23.5 degree tilt of the Earth’s axis and the planet’s elliptical orbit around the sun. In the summer months, the star reaches the highest point of the analemma; in winter, the lowest; and during the intermediate seasons the rest of the figure is drawn. Each latitude generates a slightly different shape, but they all share the same essence: an Earth that moves, rotates and tilts, not a motionless disk under a celestial lantern. The physics of time. The analemma not only reveals the movement of the planet, but also the difference between solar time and time measured by clocks. In theory, noon always occurs at 12 o’clock, but the Sun does not reach its highest point at exactly the same time every day. This variation, a consequence of the inclined axis and the unequal speed with which the Earth travels its orbit, is the reason why the analemma adopts a figure-eight shape. Science sums it up in a formula called the “Equation of Time,” an adjustment that explains why solar days vary in length and why the apparent position of the Sun advances or lags throughout the year. This mismatch is as predictable as it is beautiful, and can only be explained by a spherical planet that orbit a starnot by a flat disk with a wandering Sun that rises and falls without altering its size. The impossible refutation. In the flat earth modelsthe Sun moves on a plane, like a lamp on a table, projecting its light in circles on the surface. If that were true, the end of a shadow always observed at the same time should remain fixed throughout the year. However, the garage experiment shows exactly the opposite: a harmonic displacement that only fits the heliocentric model. Reproducing this effect in a flat world would require, in addition to an act of faith without a network, that the Sun change its trajectory, height and speed in an absurd way, violating the very laws of optics and gravity that its alternative model allows. The flat earthers themselves, faced with such evidence, barely manage to develop new explanations that are more imaginative than scientific. The method. He merit of the experiment It lies not in its complexity, but rather in its humility. Without telescopes or laboratories, a simple fixed camera and a daily routine were enough to record the annual dance of the Earth in front of the Sun. Each shadow point marked on the cement is a slap to the conspiratorial noise that floods the internet. In times when science is forced to defend the obvious, an ordinary garage has become an observatory and an anonymous user a popularizer.

Waymo lands in the great litmus test of its cars

Hello, London! With a simple and straightforward message, Waymo has confirmed that next year it wants to operate its driverless robotaxis in the city of London. For now, the company has to work with the authorities to win their favor if it wants to have full availability next year. It is a litmus test for fully autonomous driving in Europe. What is already known. Although it has been reported in numerous media outlets that Waymo will offer driverless trips next year, the truth is that this is not entirely the case. What Waymo has announced It is their intention to be able to offer this service but first they have to gain the trust of the regulators. For now, the company that was born from a spin-off of Google’s autonomous car will begin to operate with a human behind the wheel in specific spaces within the city. Once you obtain approval from the authorities, you will be able to offer this service to citizens. Why London? Waymo’s choice of London is no coincidence. It is not even the only company that aspires to put fully autonomous cars on the streets in the English city. Uber and Lyft They also have their own plans. If London ends up giving the go-ahead to any of these companies, it will be the first city in Europe to allow this service. The announcements have been coming in cascade since last June It will be confirmed that the United Kingdom aspires to allow these services from the spring of 2026. The British Department of Transport has advanced the deadlines by one year and they hope that in 2027 the services can be active throughout the country. A trial by fire. Although up to three companies have already shown their intention to put their cars on the street, what we will see in London will be the confirmation of whether the technology is mature enough so that cars circulate correctly in European cities. London, like many European cities, did not plan the center of its cities that date back to the Middle Ages. The network of narrow streets, complex intersections, roundabouts and a greater number of pedestrians is a challenge for robotaxis that must be able to process an almost unimaginable number of variables in real time. And the variety of scenarios and dangers that any car faces in the center of European cities has been presented as the main obstacle for companies that intend to put their robotaxis on the streets but also for companies like Tesla that aspire to have its most advanced autonomous driving systems. With leaden feet. Although the United Kingdom has its own plans, the truth is that Europe has been cautious in the field of autonomous driving. At the moment, only Mercedes has permission to circulate without the driver paying attention to what is in front of them. Of course, on previously mapped roads, with good lighting and a maximum of 60 km/h. That is to say, the system is as expensive as it is slow. The other actor that leads the way is Ford. The North American company has permission for its drivers circulate without hands in the United Kingdom and over thousands of kilometers within the European Union. Of course, the roads must be previously mapped and the driver must be able to take control immediately if the situation requires it. Companies, however, have been pressing for some time for Europe to expedite a regulation that never seems to come. The most active has been Tesla, which has published videos showing cars with the Full Self Driving activated to circulate completely autonomously in spaces as complicated as Rome either Paris. The security. The big problem that companies face is security. Waymo claims that its cars are 78% less likely to suffer an accident with injuries than a human. And the website where they announce their intentions in London it is a continuous reference to its security systems. The great obstacle for companies is to convince that this is true because when a vehicle of this type plays a leading role in an accident with fatalities, it generates more distrust than if the vehicle is driven by a human being. It must be taken into account that the autonomous car has to coexist with the decisions of other human beings, so the consequences, in part, of an accident may escape their control. To this we must add that the vehicle must understand without errors what it should do at all times. This can be a significant obstacle when a computer failure occurs, a loss of connection or, simply, a new situation that had never been contemplated. In San Francisco, for example, Cruise cars have been accused of hinder emergency services. What’s at stake? According to the most optimistic perspectives, a business close to 600 billion dollars in less than a decade for driving. autonomous (including the possible services that manufacturers incorporate to their individual clients. It is the great hope for companies that have already burned tens of billions of dollars. Obviously, the business is in a drastic reduction in operational costs which puts human drivers at risk. For now, in Guardian They report that taxi drivers have received the news with skepticism, pointing out that Waymo’s service in the United States is more like a tourist attraction than just another mobility alternative.

Cameron’s ‘Titanic’ was going to be a flop. Until a trailer that broke several Hollywood rules changed the narrative

In a few weeks the posthumous memoirs of Jon Landau, producer of ‘Titanic‘ and ‘Avatar‘, and frequent collaborator of James Cameron. Media as Variety have been able to access its content, and they tell of a masterful marketing maneuver: how a film that seemed doomed to failure, ‘Titanic’, was saved thanks to an intelligent trailer. It was sinking. Before the release of ‘Titanic’ In 1997, there was a certain pessimism in Hollywood and in the press about the film’s chances of success. With a then-record budget of $200 million, constant delays during filming, and negative rumors about the development of the production, many experts and media assumed that the film would be a financial disaster. Landau says that he was famous an article from ‘Time’ magazine in which the possible future of the film was compared to the real fate of the ship with the onomatopoeia “Glub, Glub, Glub…” Too much noise. But as he says in his memoirs, titled ‘The Bigger Picture’, Landau knew that “perception becomes reality”, even though expectations were not good: the jump from 100 to 200 million dollars brought to mind another major failure (and with a very marked aquatic component as well): ‘Waterworld’ by Kevin Costner. Paramount’s marketing team proposed a conventional trailer. Landau described it as a “John Woo-style trailer”, meaning “quick cuts and booming music, gunshots and screams. It made the movie look like an action movie that just happened to take place on the Titanic.” Cameron and Landau knew this wasn’t their movie. Four minutes or so. The decision they made was seemingly counterintuitive: an exceptionally long trailer, four minutes and two seconds. Before, they had to fight for a long time with Paramount executives, who initially wanted a shorter trailer oriented solely towards action. Landay and Cameron argued that a longer trailer was necessary to convey the magnitude and complex narrative of Titanic. They presented it at the ShoWest event in Las Vegas, a key convention for theater owners. Kurt likes it. The trailer had an immediate and favorable effect among attendees, decisive for the good distribution of the film. It also had a positive impact on stars like Kurt Russell, who helped spread the word that they were watching a great film. The actor, sitting at the Paramount table, stood up and shouted, “I’d pay ten dollars just to see that trailer again.” Since then, even the initially skeptical press began to reconsider the film, marking a turning point in public perception and hopes for commercial success. Change in narrative. The trailer not only showed what no one had seen and how the film worked (the memories, the romance, the action, the gigantic scale), but it also redefined the conversation from rumors of failure to raising the possibility of it being a success. The film was released in December 1997, became the highest-grossing film of all time and won 11 Oscars. Another victory for Cameron, although with this one he didn’t have it with him all the time.
