Those who know how to ask 100 questions to Chatgpt and those that are formed with an answer

by

When Nityesh Agarwal, an engineer from Everyspent two weekends learning about special relativity with ChatgptHe did not just ask him a question. Not ten. Were More than one hundred The questions he asked until Einstein ceased to be a name in his books to become ideas that could explain to anyone in five minutes. A software engineer, without physics training, achieved what it used to require much more regulated training time: Understand why time slows near the speed of light. The difference was not even caused by the chosen model. In fact, He used more GPT-4o than the brand new O3 because he felt that he better understood his doubts. The difference was in your method: Ask until exhaustion. Ask for metaphors. Draw diagrams when it was stuck. Share each epiphany to confirm that you had understood. He used the AI, in short, such as what can really be: A tutor with infinite patience that never tires of reformulating the idea from different angles until the student understands. And there is a little commented problem: Most people use chatgpt and company like a vitaminate googlelittle else. One question, an answer, next topic. An advanced calculator, a refined translator. How to have Internet access and just use it to watch viral videos. Ahem. Nityesh discovered that the bottleneck of personalized learning is not so much the intelligence of the machine and the patience and insistence of the student. AI can teach anything to anyone. But it requires that we be as obsessive as Nityesh during those two weekends. And so he is born A new self -taught class: People who understand that after the Internet, AI is its second great revolution. If the Internet democratized access to knowledge, LLMS They democratize access to personalized teaching. Some people make them more vague. Others make them unstoppable. The advantage is no longer to have access to information, but in the ability to ask the right questions and have the patience to continue asking until everything fit. Nityesh has demonstrated it In comic strips.

When the British wanted to terrorize the Nazis during World War II, they chose a peculiar weapon: pump rats

by

Think about the Second World War is to think of large -scale battles, tremendous operations and epic skirmishes. And, although it is true that there were imposing deeds, we are also tremendously influenced by cinema and video games. Because doing one spy movie or a ‘Save Soldier Ryan‘is’ easy’, but … and one above the inflatable tanks or of pigeons piloting missiles? That is more complicated. Because, In a moment of despaireverything goes. And if the Americans gave them to devise a bomb -loaded bomb To set the Japanese houses, the British be occurred Something that looks like a joke, but that made a lot of sense: filling rats with plastic explosive and waiting to be triggered in Nazis facilities. The Germans They were caught at firstbut far from being a fudge, it turns out that discovering the pump rats was what made the operation a success. Exploding Kittens Rats 1941 was a key year in the Second World War. The Nazis gave the green light to the invasion of the Soviet Union, the Japanese attacked Pearl Harbor, the United States entered the war officially and began the Mass deportation of Jews to the extermination fields. There were too many open fronts and the war had just become a global phenomenon, but the British wore years fighting the Nazis. The first quarter was crazy, with bombings of the British to German possessions and intense German bombings in English territory, attacking cities such as Liverpool, Manchester, Birmingham and, above allLondon, who for almost two months He suffered night bombings. Apart from in the air, the war was fought on land, and one of the plans of British intelligence revolved around the industrial sabotage. Damaging the factories, Germany would lose war power, it is evident. Thus, the British Special Operations Office, or SOE for its acronym in English, devised a strategy which would consist in wasteing pump rats near German infrastructure. They would not put a “backpack” pump to the rat and leave it free out there, no: the plan It consisted In getting dead rats, open them on the channel, empty them, fill them with plastic explosive, place a detonator that would come out for what would be the anus and strategically locate each animal near the boilers of the factories and key buildings of the Nazis. The goal? That when a worker found a rat, he directly threw it into that boiler, turning on the wick and causing the structure to fly through the air, interrupting the Nazi war machine. That said, the truth is that it was a brilliant plan because it was easy to think that workers would not bury the animal or throw it out there, since it could spread diseases, that cremation in the boiler being as fast. And they got with a hundred of them. There was a problem: the Nazis intercepted the first sending of explosive rats before they were deployed. Far from thinking that the plan failed, it turns out that The caught was much more effective that what they could have achieved if the rats had managed to be thrown into the boilers. And the reason is obvious: the Nazis, when discovering the Artimañathey wondered how many explosive rats before that interception they could have placed the British. That sowed a more explosive doubt than the rat itself because the Nazis launched campaigns to search for similar devices and, if they found a dead rat, began to tremble. Would it be a rat or a pump? Although any exploded, the operation was never considered a psychological success for the general paranoia that caused in the German ranks. The possibility of such unconventional sabotage forced the Nazis to divert resources to counteract similar threats. In the official SOE archives, they detail that the device “caused considerable problems to the enemy, but not quite in the way it was intended.” In the end, it was an effective form of psychological war because there were Germans trying to counteract a non -existent threat. As concluded Soe himself, “the problem that rats caused to the Nazis was a much greater success for us than if the rats had really been used.” Today is an anecdote or an object of collecting, like the main image rat, sold In 2017 for more than $ 1,800. Also as a much less crazy idea than those of those pilot pigeons … or that of the incendiary bats.

In Spain a book is published every six minutes. It is the symptom of a bubble that does not stop inflating

by

When talking about the health of the editorial industry in Spain, publication figures are usually used to justify the good condition that the book business lives. However, rapid accounts lead to thinking perhaps just the opposite: excess launches may be hypertrophy the bookstores, which are suffocated by a series of very uninjury side effects. How much is published? The Latest public data from the Ministry of Culture They speak of 92,000 books a year with ISBN, that is, more than 250 books a day. Every minute, six books. And that telling only the launches with legal deposit, that is, we do not count the self -edge (last year, it was around the three newspapers … By author) For platforms as widespread as Amazon. That do not count as part of the editorial cake but add thousands of potential titles per month to the mountain of slopes of the troubled readers. Success is what is sought. Why so much novelty? There are a number of reasons that make up a very complex ecosystem to explain this production overdose. On the one hand, it is an editorial strategy for compensate for the fall in sales by book: except Bestsellers And specific successes, the books sell less, the runs are lower and the publishers multiply their offer to cushion it. From there comes a constant publication and search of that new success that supplies the previous one. The fact that Increase global income Although the runs fall, it is proof that The strategy works. Oihan Iturbide, former Editor, counted in the jump that “the editorial industry looks more like a fast food chain than a restaurant with a good homemade menu: the key is in volume, not in quality.” Many are. On the other hand, there is the proliferation of new publishers: In 2024Spain had approximately 3,160 active publishers. It does not imply a very notable change with respect to previous years (comparable to 2016, and notoriously less than 3,564 of 2009, year with Spain in a very different economic context). Of these, only about 2,000 publishers launch more than 10 titles per year, and only 13 exceed 700 annual titles. Is it a note of diversity and vitality of the sector? Yes. But also of the enormous contrast between the large Spanish editorial groups (Planet and Penguin Random House, more Santillana in the educational field) and the rest: According to the Federation of the Editors Guildthree out of four books come from these groups. The distribution fish. This overproduction atmosphere (Rubén Hernández, by Errata Naturae, Talk about those 92,000 books per year “One third is returned to the darkness of the stores and is probably guillotine”) is contaminated with the complex distribution system in Spain. This is also Hernández: “The publisher publishes with a price (…) of 10 euros and it is sent to the distributor. The bookseller buys it with a discount close to 35%, from which he obtains his benefit, and pays 6.5 euros to the distributor, which stays 2 euros and pays the remaining 4.5 euros, that he does not pay him, but offers him a loan. “ The snowball continues to grow: “In turn, the distributor claims to the editor of his 4.5 euros, which he does not pay him, so he contracts a debt. And to reimburse it, the editor has no choice but to invest the 4.5 euros he has won (but he must) in another book that, after arriving at the bookseller, activates his credit, while the distributor enters another 2 euros. Book, the editor and the bookseller receive debts or credits. A vitiated system very similar to a bubble that continues to grow without brake. Are all bad news? No: the evidence that it is published too much allows publishers to realize that The situation can become unsustainable. Possible solutions to Very vicious system of returns in bookstores. The excess of supply is not bad in itself, unless it leads to overproduction and atibor the system until it is bursting. It is obvious that six books per minute are too many, but … who is the first to start with the cuts? Header | Photo of Pierre Bamin in Unspash In Xataka | Adult books are therapeutic.

There is a strategy to focus and combat multitasking: compartmentalize tasks

by

We live surrounded by stimuli and notifications that fight for monopolize our attention. The problem is that, what begins as “only a view of notification in case it is something important” becomes two hours of kittens videos. Such and as an account Berto Pena in his blog and in his book ‘Superhabic‘, compartmentalizing tasks helps protect your time and favor concentration, something that has become a challenge to take better advantage of each day and Keep the focus In what really matters. Compartmentar is a simple technique that can be applied to any type of task, but with which very good results are achieved. HE Avoid procrastinationimproves the Classification of priorities And prevents tasks being extended more than necessary. Assign an order and time limit to your tasks Comparting tasks consists in defining specific moments and times for certain activities that we know we must do. For this, a mixture of productivity techniques such as ‘Time Blocking’ To assign a specific hole in the calendar that we will dedicate exclusively to doing that task. When assigning a certain block of time to each task, it is prevented the work from extending more than the account, thus fighting the effect of the Parkinson’s law. This productivity law states that “work expands until the time is available for it to end.” In this way, the effort dedicated to each task is delimited and mental fatigue is prevented while preventing tasks from eternalizing. On the other hand, when establishing a period of time at a given time, it is Promote planning and is conditioned to commit to the task. Without excuses or postponements. After all, one of the greatest friction of procrastination is start doing homework. The compartmentalization of the tasks forces to adapt the nature of the tasks to the time blocks. In this way, if a task is too big for your daily day, it is easier to divide it into smaller tasks that occupy less time and program them in successive days. In this way, the motivation is maintained to complete a task that you have already started taking advantage of the “Zeigarnik effect“: the natural brain trend To finish those tasks that you have already started, even when it is not mandatory to do so. Your brain does it for a unstoppable need to close a door that was kept open. Advantages of segmenting tasks in time blocks As we have already mentioned, one of the main advantages of this technique is the Concentration improvement and the multitasking reduction. By dedicating an exclusive time block to an activity, the temptation to jump from one task to another is reduced. Another advantage of this technique is that the Regularity and discipline. Comparting tasks helps to build habits by assigning a certain task in a recurring time strip. When establishing that routine, the brain ends up raising awareness and integrating the habit associating a certain day and time to an action as one of the Habits triggers to those referred to by James Clear in his book ‘Atomic habits‘. This strategy also facilitates management and organization of tasks In the day to day. When distributing tasks in compartments throughout the week, a clear vision of what should be done and when. Thus, improvisation is avoided and each task receives the attention and time it needs. Finally, companding allows greater flexibility against unforeseen events. Something very useful for long projects. Although the technique provides structure, margin also offers to adapt and if an urgency arises, it is easier to readjust the time blocks without sacrificing the time dedicated to each task and without causing a domino effect on the rest of the scheduled tasks. Applying it is easy, but it must be progressive The first step to compartmentalize is Identify tasks and activities that will be programmed in time blocks. To start, it is easier to do so with short and recurring tasks, so that the results are appreciable in the short term. Read every day for an hour, do an hour of exercise, spend daily time to review the notes of that subject that costs you, etc. Once identified, they are assigned specific gaps on the agenda being realistic with the duration that each task needs. Do not worry if one day you have plenty or you lack time, just take it into account for the next time you program that task. It is a learning process in which it will be necessary to apply corrections. What should be immovable It is your commitment With scheduled tasks. If it’s time to do it, Focus on her And forget everything else. No pauses or interruptions. Concentration and deep work until the time block ends. The breaks, like any other task, must also be programmed and respected to avoid exhaustion. It is recommended to start little by little, with two or three tasks a week, and add more blocks progressively as the routine is consolidated and the first results begin to be obtained.

Córdoba has been trying to finish a road for 20 years. Now they have encountered a problem: Ruins Mozárabes

by

Doing works in a city like Córdoba is a risk task. From time to time, in Spanish cities we find new vestiges of previous eras. An example is the ruins under the door of the sun or the Otero orchard deposit in Mérida. Córdoba is another level and, during preventive excavations under the layout of a future and important road, they have found new Christian ruins. They are not just a few more archaeological remains: this finding provides unique context to the coexistence between Christians and Muslims in Islamic Cordoba. Short. The northern round of Córdoba will be the road that It will close The city ring. It is a complex project that has been carried out in phases and that has been controversial Due to neighborhood complaints motivated by noise that will generate the increase in traffic. During preventive excavations, and how we read in Cordopolisthey found something that will further delay the project: a set of structures that date back to the seventh century. And the date is relevant because it would contribute new context to the Córdoba of those first decades of Islamic domination. By layers. Córdoba is a large city, but the Islamic Córdoba was even greater. With the passing of the centuries, the city was diminishing due to the new urban projects, which were building on the remains of the past. Mosque itself is an example of that construction in phases and, although in an exaggerated way, of that building on the above. When it is excavated to do works, it is not uncommon to run with remains of Islamic neighborhoods, but the interesting thing about this new finding is the cult difference: the Christian. A cult that, due to the progressive Islamization from the city, he left displacing towards the most peripheral areas. The remains. In Cordopolis, Alberto León, professor of archeology at the University of Córdoba, comments that there was a record of the destruction of Christian temples at the dawn of the seventh century. Subsequently, Abderramán’s “pact” was allowed, allowing the coexistence of the cults. The problem is that no remains of those constructions made by the Mozarabic. That is why the complex discovered under the future North round Be so relevant. Presents Tapial walls (clayey earth compacted with blows) and a pool of about 50 meters. Archaeologists have been inspecting the place since the end of last year, and it is now when they point out that it would be a monastic building, probably divided into areas for men and women, with clarifying columns arranged, as you can see in the photosaround a patio and that the pool could be a baptistery. The lost basilica. Ángel Ventura is a professor at the University of Córdoba and one of those who is inspecting this monastic complex. In Córdoba newspaper He launched the hypothesis that the ruins could belong to a possible basilica in honor of Santa Eulalia de Mérida. It was a martyr that had great importance for the Cult in the city And there were documents that implied the existence of “their” basilica, but without having been found. Clue. In the end, this discovery will allow to have more context about the coexistence between Christians and Muslims, but it is also relevant because, according to Alberto León, “is one of the two examples of existence of a Christian cult complex in Islamic neighborhoods.” The researchers continue to study the place to determine their function, chronology, when it was abandoned and launch hypothesis about the coexistence between the different cultures of the city. What is clear is that there had to be many more like this in the suburbs, so future excavations could even show more context about that peculiar era of religious coexistence in the Islamic Córdoba. And also that it would be necessary delay or even rethink the work of the road to be able to study this important finding.

The San José Galeon sank in 1708 with a treasure of 20,000 million. A handful of coins has revealed its destiny

by

Throughout the planet it is estimated that there are close to three million Of pecios, vessels that caught in their day and now rest at the bottom of the oceans, turned into sentences of marine life. This list is included from transatlantic as The Titanic to destroyers of World War II, abandoned boats or colonial caravels. Few arouse the interest of San Joséthe galleon sunk in 1708 off the coast of Colombia with the wineries full of gold, silver and gems, a treasure that some value in almost 20,000 million of dollars. His exact whereabouts was a mystery for centuries. Now Colombian archaeologists believe Having located it without a doubt thanks to a track that confirms the opulence of his treasure: the gold coins that he transported on board. A Milmillonario Treasury. In his day the San José was an imposing galeon, a large ship of 40 meters of length12 of manga, three masts and 64 cannons built in Guipúzcoa commissioned by King Carlos II. Your mission: work on the Indian fleet. Neither its power nor its dimension avoided however that the history of San José was brief. The ship ended up sinking from the coast of Colombia in June 1708, only a few years after its launch, beaten by the cannons of a squad of British privateers during the Battle of Barúin full war of Spanish succession. The most curious thing is that the legend of San José began just then, after its shipwreck. And the reason is simple: in addition to a crew formed by hundreds of sailors, the galleon loaded with gold, silver and gems, among other treasures. There is talk of a loot of 200 tons that today would reach a value of billions of dollars. Some estimates place it in 17,000 millionothers in more than 20,000. There are also those that reduce that calculation, but without leaving the land of the thousands of millionsan imposing treasure. And where is the San José? For centuries that was the great unknown. It was known that the wreck was In the Colombian Caribbeanbut … where exactly? What were your coordinates? In 1981 A company announced to hype and saucer having found the Galeon and allegedly delivered the information to the government in exchange for keeping a part of the treasure, but the story soon complicated. In 2015 The country’s authorities claimed to have located the remains of the Spanish ship in a different place, which tightened the disputes about who has the merit of the finding and (more importantly) the rights over the treasure. The big clue: the coins. Historical discoveries often depend on small details. And underwater archeology is no exception. Although experts have been convinced that the vestiges resting in front of the Colombian coast are the remains of San José, a New research published in Antiquity He has just reaffirmed the identity of the wreck. And in a fairly peculiar way: analyzing the gold coins located in the underwater deposit, at approximately 600 meters deep To get it a Colombian team undertook Between 2022 and 2024 Several expeditions focused on the remains of the wreck. He did it With the help of a rova non -manned submarine vehicle that allowed experts to obtain high resolution photos of the coins that rest on the site. Thanks to techniques such as The photogrammetry They were also able to draw a three -dimensional reconstruction of the wreck and several models and digital replicas of the environment. And what did they discover? They found Macuquinashand coined coins and that were used for more than two centuries in the trade of the Americas. With the help of high resolution photos taken in situ – the Colombian Institute of Anthropology and History assures That no object object was extracted – experts discovered that the pieces have an average diameter of 32.5 mm, weigh 27 grams and are coined with revealing designs. On the obverse, the coins show a variant of The Jerusalem Cross (A large cross with four smaller) next to a shield with castles and lions, symbol of Castilla y León. On the back they carry the Hercules crowned columns On waves, which relates the pieces to the Lima Mint. Squeezing clues. They are not the only clues identified by archaeologists, who have identified a “L” that seems to refer to Lima, an “8” that shows the value of the currency and an “H” related to the brand of Francisco de Hurtadohe Major trial of Indies in 1707. In the central part of the coins the legend “PVA”, “Plus Ultra” is also appreciated, a wink to the maritime expansion of the Spanish monarchy. The information is completed with three digits (707) located at the bottom of the pillars, a reference to the year in which the coins were coined: 1707, just before the San José sink into the Caribbean. Why is it important? Because all these data are clues that help to better understand the site and the circumstances in which the galleon that rests there. “Unraveling the characteristics of the currencies helps to determine the age and origin of the wreck”, collect the article. “First, it establishes a temporal frame: the sinking had to occur after 1707. This, along with other tests, such as the presence of Chinese porcelain Kangxi And inscriptions in the cannons dating from 1665, suggests that the ship sank at the beginning of the XVIII. “ “Corroborate identification”. The coins also give clues on the route that must have followed the sunken galleon. “In the Viceroyalty of Peru, several gold mines were registered, mainly in Puno and Huamanga. It is likely that the material to coined the coins would be obtained from these mines and processed in the house of La Moneda de Lima, which resumed operations in 1683 and began to coined gold in 1696,” Experts reveal In your study. All those evidence, added to what historians already know about colonial history, leads them to A resounding conclusion: “The set of tests corroborates … Read more

We had been thinking that creatine served to train better. It turns out that the greatest benefit was in the brain

by

Creatine is the star sports supplement and one of the most studied. As with the coffee and caffeineis surrounded by Myths And we have been investigating its benefits for decades when practicing sports. AND studies More recent have placed up to creatine supplementation by pointing out that the muscles are not the only ones that benefit from their effects. The brain also appreciates it. Physical performance. Creatine is a nitrogen compound that occurs mainly in the liver and that humans also obtain through the consumption of meat and fish. Although there is controversial studies in this regardcreatine really is stored in the form of phosphocreatine, acting as a booking Immediate energy. This means that, when the muscles are subject to intense efforts such as a sprint or a weightlifting, phosphocreatine acts to regenerate the essential energy molecule for muscle contraction. This allows muscles to maintain high performance for a little longer. It also increases cell hydration and stimulates protein synthesis that leads to cell growth. Enhancing the brain. Being such an studied supplement implies that numerous ways have been found in which creatine benefits our body, reducing inflammation, oxidative stress and muscle catabolism. And, along the way, they have found benefits additional that have not to do with the growth of our most ‘visible’ muscles. It is increasingly recognized for its general health benefits, including cognitive function and healthy aging. Although the brain is not a muscle, it also stores creatine and can benefit from its energy effects, such as supplying energy quickly to neurons. A applicationfor example, it is the good brain function in times of lack of sleep. Essential. This is something observed in several investigations, being carried out by the team of Dr. Richard Kreider, director of the Exercise and Sports Nutrition Laboratory of the Texas A&M Universityone of the last to contribute to the conversation about its benefits. According to Kreider, the regenerative paper and as a rapid “fuel” is relevant for both muscle and brain. “When the body is stressed, as in exercise or in metabolic conditions such as those caused by some diseases, phosphocreatine is needed to maintain cellular energy,” says Kreider. Neuroprotection. Others studies They point to added benefits, such as acting as a neuroprotective, helping in the recovery of brain injuries and showing potential to reduce mitochondrial dysfunction, key factor in neurodegenerative diseases. It also helps reduce the feeling of tiredness, maintaining alert and performance in demanding cognitive tasks. How much? One of the big questions when creatine begins to be taken how much is necessary to fulfill its function correctly. It has been experienced with several doses and there is a kind of agreement that would have to be taken between 0.07 and 0.1 grams per kilo of weight per day to optimize physical performance. For a 70 kilos person, this is equivalent to 5-7 grams per day. Kreider fits those accounts by resorting to that ‘cycling’ practice that was recommended a few years ago. Thus, the researcher indicates that about 20 grams would have to be taken daily for a week to “help load the muscle”, but later it could be taken between 5 and 10 grams a day to maintain creatine reserves that contribute both to the muscle and the brain. In Vegans and vegetariansIn addition, it is essential because for a omnivore It is difficult to fill the phosphocreatine reserves with your diet, not consuming meat or fish the difficulty is even greater. Security. Due to the myths that we commented before (such as hair loss or that it is an anabolic substance, among many other discharges about creatine), it is easy for people to not trust this supplement. Kreider states that “there is absolutely no data that supports any negative side effect reported anecdotally on creatine,” reaffirming that it is “safe and important to all, not only for bodybuilders and athletes.” Images | Xataka, Scientifanimations In Xataka | Tell me what color is your banana and I will tell you what it is for: the importance of maturation point at nutritional level

Quantum computers threaten encryption technologies. This is the reason why we do not have to panic

by

This month is being very exciting for enthusiasts who follow up the current Quantum computers. Xanadu, a young Canadian company founded in 2016, has announced that Plan to have ready before 2030 A quantum computer of one million photonic ulna with error correction. However, it is not the only company that intends to make this milestone come true. IBM plans to make available to its customers in 2029 ‘Starling’its first large -scale quantum computer endowed with the ability to amend your own mistakes. The main problem facing quantum computers in the field of error correction is noise, understood as the disturbances that can alter the internal state of the cubits and introduce calculation errors. In any case, if finally the correction of errors comes to fruition the prototypes of quantum computers that we have currently will leave behind their status of prototypes and allow us to face really significant problems. And presumably Bitcoin encryption and other cryptocurrencies will fall. We are facing a worrying challenge Quantum computer experts have known for several years that quantum computers They will end classical cryptography. That moment came in May 2024. A team of researchers from the University of Shanghai (China) led by Professor Wang Chao used a quantum computer D-Wave for I successfully violate the SPN encryption (Substitation-Permutation Network), which is a cryptographic algorithm that is used to encrypt information. This encryption is the cornerstone of, for example, the AES standard (Advanced Encryption Standard), which is used a lot. These scientists published the result of their research in An interesting article entitled “Public Cryptographic Attack Algorithm based on quantum processing with the advantage of D-Wave”. However, this is not all. And it is that in the middle of May several Google researchers They published an entry In the blog dedicated to the security of this American company in which they support a crucial premise: an integer RSA (Rivest – Shamir – Adleman) of 2,048 bits can factor in less than a week with a quantum computer of less than one million cubits. An RSA integer of 2,048 bits can be factor in less than a week with a quantum computer of less than one million cubits Bitcoin, Ethereum, Solana and the other modern cryptocurrencies use a cryptography technique known as elliptical curve that is more robust, efficient and difficult to break than RSA, but its mathematical foundations are similar to those of the latter encryption algorithm. In fact, according to Google scientists signed by the article that I have mentioned above, if the future quantum computers will cost them less than initially breaking the RSA encryption, the cryptography of elliptical curve will also fall with relative ease. So far we have talked about cryptocurrencies, but it is crucial that we do not overlook that encryption technologies have a fundamental role in our daily lives. In fact, WhatsApp and Telegram use them to encrypt our messages; Banks turn to them to Protect our transactions And every time we buy something on the Internet, it is the encryption that is responsible for protecting our credit card information. These are just some of the applications of this technology. Keith Martin, professor of the Information Security Group at the University of London (England), has published in The conversation An interesting article in which it addresses this topic. And it reminds us of something important: the threat of quantum computers to encryption technologies is very real, but we have no reason to panic because many researchers have been working on the solution to this challenge for several years. In fact, most of the theoretical work is already done. In 2024 the National Institute of Standards and Technology (NIST) of the United States published an initial set of standards that includes a post -mecuantic keys exchange mechanism and several postcuantic digital signature schemes. The work that is already done invites us to anticipate that at the time the relevant quantum computers appear from a cryptographic point of view Technologies will already be ready They will be able to protect our information. And in all likelihood these techniques will also be in the hands of quantum computers, such as Juan José García Ripoll holdsResearcher at the Institute of Fundamental Physics of the Higher Council for Scientific Research (CSIC).

Drinking a glass of water before eating is one of the most common “tricks” to lose weight. Science has something to say

by

With the summer just around the corner, many people seek to lose weight quickly. We have seen it with challenges like Skinnytok, Shots of vinegar either Liquefied Céspes. In the midst of so many “miraculous solutions”, there is a advice that stands out for its simplicity: drinking a glass of water before each meal. It sounds very easy, but is it another myth détox or is there something true? A glass of water. At first glance, it looks like a quite simple premise. Drinking water before eating can “favor satiety” and help eat more conscious way, as the media have explained as Telva either Vogue. In theory, when occupying space in the stomach, water would reduce the feeling of hunger. But like He has warned Dr. Robert H. Shmerling, of Harvard’s Faculty of Medicine, in an article for Harvard Health Publishing, “human physiology rarely follows such simple rules.” Science behind. Dr. Shmerling He has evidenced That it was a premise “too pretty to be true.” In his article he has detailed that although drinking water before meals can generate a mild fullness of fullness – to activate the stomach mechanoreceptors – the effect is limited and passenger. In fact, as you have continued arguing, some studies support the idea in older peoplethere is even evidence that suggests that, within a hypocaloric diet, who drink water before meals can lose more weight in 12 weeks than those who do not. However, there is a nuance to take into account and that is that There is no robust evidence of long -term effects or in large populations. And other associated theories –Like cold water burns calories by thermogenesis– They have been denied in recent studies. Where there is consensus. The point is not in so much to drink extra water, but in what is stopped. Changing soft drinks, energy drinks or alcohol for water can have a real effect on weight loss. According to May Clinicthat simple gesture reduces the total consumption of calories without conscious effort. In addition, staying well hydrated improves physical performance, exercise resistance and recovery. Not because water “weights”, but because it helps sustain a more active and healthy lifestyle. The shortcut culture. The popularity of tricks like this also responds to a social need: to find fast, simple and effortless solutions to a complex problem such as weight control. In a society obsessed with thinness – especially among young women – they proliferate The calls Life Hacks that promise immediate results. As He already explained for Xataka The psychologist specialized in TCA, Sara Bolo, the worrying thing is that many of these tips end in apparently “healthy” behaviors, but hide eating disorders. It is simply water. In a context where “fast tricks” abound, it is advisable to remember that, as Dr. Shmerling has summarized: “If you think it works for you, there is no damage. Remember that no glass of water replaces a balanced diet.” Image | Unspash Xataka | Nostalgia for the 2000s has brought something else: the obsession with flat belly and radical thinness

convert email into a list of tasks

by

The email, that novelty relic whom no one has been able to kill, is about to suffer its greatest metamorphosis. Hotmail or Gmail They brought storage and search capacity, clients of third parties such as Spark introduced a new way of managing them. What is coming is deeper: AI is making The mail goes from being a writing activity to a decision activity. To write answers to mark boxes. The first systems are already here: Gmail summarizes long threads and develops basic ideas. Outlook suggests short answers. Apple Intelligence summarizes, rewrite and expand paragraphs. Spark Directly take your previous mails to emulate your voice and generate answers with your style. It is just the prologue. When this goes more, We will stop writing most mails, we will simply approve a proposalor we will clarify it. Or we will choose between certain options. In the future, our mail clients will present each mail not as a text to read, but as an action proposal: Accept meeting Thursday at 11:00 a.m. Thank information and ask for more details. Decline proposal. A touch and ready. It is an inevitable change because in the background mail has always been a task management system disguised as communication. Most professional emails ask for something: confirmation, information, decision, action. The AI ​​simply naked this reality, eliminates the liturgy of forced courtesy and repetitive writing. I have written thousands of times “thanks in advance” or “good weekend.” The machine can do it for us. Even in our style. And it will free us from That corporate slavery For what really matters: decide. The end of the game will be something we already anticipate: Bots talking with bots. As Mg Siegler points outthere will come a time when the AI ​​will automatically schedule that meeting with the AI ​​of your contact, will negotiate dates, send reminders, will write the subsequent act, even ask how your child after the operation, perhaps. Humans We will appear for decisions that really require human criteria (Some will also want to delegate that, but It is another topic). And the mail will not disappear, but it will largely be somewhat invisible. And by automating routine communication, we will recover the communication that is worth it.
