When in 1907 a doctor tried to demonstrate the existence of the soul using a scale

by

When We are going to bedthe brain Beast begins to work. It is when we review the day, We can think of great ideas that we do not point and ask ourselves questions of all kinds that We do not usually remember the next morning. Duncan Macdougall did remember what may be asked just before sleeping: How much does the human soul weigh? The concept of soul It is complicated, since there are those who see it as an intrinsic element to the body, but also something that fades “when we die. Macdougall, a doctor from Haverhill, Massachusetts, had to say “science is not done alone” and got to work to test a hypothesis. What hypothesis? That, if the soul exists and is inside the body, it must have a weight. His theory was that, if at the time of death the soul escapes our body, it could measure its weight. And he got to the work of the most handmade work possible. Also of the least scientific. Science is not done alone, you have to do it He is romantic, almost tender, now think about his reasoning. But he had all the logic of the world to respond to something so complex: at the time of death, there should be a detectable loss of weight because the soul abandons the body. As if the soul were the “pilot” who jumps from the plane before crashing. To test his theory, Macdougall built a fairly special scale: a bed mounted on a weight capable of detecting differences of up to five grams. His plan was not very ethical, but all for the sake of science and to try something so important: place dying patients on top of the scale and monitor weight changes just before and after death. It took his thing. Between 1901 and 1907, Macdougall conducted this experiment with six terminal patients. Four of them had tuberculous, one was diabetic and the other had no specified causes. They were chosen conscientiously and should be people who had conditions that depleted them mentally. They had to move as little as possible when they died so that the measurement was more precise. Macdougall was pending at all times of those final moments of the patients and, when he detected that one was about to die, he placed the bed on the scale and made the measurements. And the results soon arrived. According to the doctor, the first patient lost, exactly, 21,26 grams just after exhalation. It is the most famous case and the one that gave name to the experiment. The second patient also lost weight, but the amount was not recorded correctly. And with the other four … Things were even more complicated: the technical problems when registering the weight appeared for two other records, another showed a gradual loss (he died with his mouth open and Macdougall said it could be air) and another showed no changes. For any scientific eye, the success of the experiment would have been very questionable, but the doctor clung to those 21 grams of the first death to affirm that this was what weighed the soul. In fact, he did not stay at Anecdote: he published a study in the magazine American Medicine with the title “Hypothesis Concering Soul Substance Together With Experimental Evidence of the Existence of Such Substance”, although before it had already appeared in the New York Times. With animals, MacDougall went from thread Although MacDougall ‘chained’ that data, in his internal jurisdiction he should know that he needed another control group. If it had taken six years to weigh six dying, I could not “waste” more time, so he tried to try his theory with animals. There was some red flag in all this. The New York Times article published before the scientific article To begin with, Macdougall was convinced that humans had a soul, something that animals lacked. He had already observed “problems” when measuring the weight of the human soul, so everything that was a scale without measurement changes in the case of animals, he would take it as confirmation that, indeed, animals had no soul. The experiment was already conditioned and Macdougall ended up measuring the weight of a fortnight of dogs. The researcher wanted to use sick or dying dogs to prove his thesis, but did not find enough and There are those who point that, directly, poisoned healthy dogs. Scientific community with the lifted eyebrow The doctor’s results were not long in causing a stir and there was another doctor who considered the experiment a hoax. Augustus P. Clarke argument That everything was easily refatible from the medical point of view: when we are in that situation, the lungs stop cooling the blood, the body temperature increases and the skin sweats. And in the case of animals, as they do not have sweat glands, because they do not lose weight after death. Macdougall did not convince and starred in a ‘Beef’ in medical magazines for a few months. Over time, other scientists joined the MacDougall Experiment Discrediting process, being a clear case of rejection by the scientific community both for the methods and for the “fraud” when obtaining the results. Apart from randomness, One of the criticism is that six cases do not represent a reliable sample. In fact, in A subsequent investigation With sheep, lambs and rams, it was observed that, indeed, the weight varied after death, but they did not lose it: they won it. Specifically, from 18 to 780 grams that they won at the time of death, but that over time lost to recover the initial weight. However, it is undeniable that Duncan went down in history. Not for what I would have liked, be that person who showed that the human soul had a weightbut as an example of Selective informationhow to use a vague fact to affirm a preconceived idea. Also by that scientific spirit that, although poorly applied, tried to use evidence to measure something as … Read more

The Mercedes Concept Amg GT XX is the Mercedes C111 of the future. And to demonstrate it, it has turned around 300 km/h

by

It is difficult that Mercedes’s position regarding the electric car does not mislead us. His Electric Mercedes It promises autonomies and consumption hardly comparable to any of its rivals. His proposal is that of a car with that of forgetting any plug. Your electric Mercedes, which promises Homologge almost 800 kilometers of autonomy with an 85 kWh battery (ridiculous consumption of between 12.2 and 12.5 kWh/100 km), it looks like the direct heir of the Mercedes Vision EQXX. That prototype, which en Xataka We could tryhe directed his efforts to aerodynamics, very high battery energy densities and very low consumption. That is, the bet was not to achieve the maximum possible autonomy “to the gross”, increasing the battery capacity well above 100 kWh. The way was the opposite, having a lot of energy available but taking advantage of it very little. While the electric Mercedes filled headlines (some for worse), the company insisted again that it had to keep investing in combustion engines. His CEO, at the head of acea, He has sent a letter to the European Commission where he asks for this: flexibility in adoption to the electric car. And yet, in Mercedes it seems that something very fat is being cooking. We do not doubt that other laboratories of car manufacturers are handled juicy things but Mercedes has something good: it takes out its theories to walk. And thanks to that we can see cars like the Mercedes Concept Amg GT XX. Why does an electric car have less autonomy than the announcing 25 records of a tacada Just when the 60s died, Mercedes presented in society a groundbreaking prototype: The Mercedes C111. During its four generations it was shown that this car was the perfect basis where to try each and every one of the advances that the company had in hand. Under his body passed from diesel engines to rotary engines. It is no accident that the Mercedes Concept Amg GT XX It will appear in society with the orange color that identified that mythical sports. A little over two months ago, the company made this public 1,360 hp prototypea 360 km/Hy peak speed a soundtrack of a V8 … that, of course, you will not find it under its body. The technical data were surprising. To get this prototype to become the most powerful and fast Mercedes-AMG ever manufactured, use three axial flow engines (one in front and two on the rear axle) with a battery refrigerated by immersion (we will now see the details) with an 800 volt structure that allow loads of up to 850 kW as a maximum peak. According to the brand, they allow you to recover 400 kilometers of autonomy in five minutes. To this is added an aerodynamic coefficient of 0.198, almost matching the Lucid Air (0.197) and completely closed tires that not only prevents creating turbulence, they are also responsible for the front air flow not diluted in the passage of the vehicle and it is not until the rear axle is overcome when it is dismissed from it. With all these incentives, it only was waiting to see What was Mercedes of When he decided to throw himself to a test track. That happened only a few days ago. Mercedes has put his concept AMG GT XX at full performance for eight days in the Italian Nardò test trackknown for its speed and for being the place where for the first time the Mercedes C-111-IV exceeded 400 km/h. This time, the Germans put their heir to turn to the immense 12.68 kilometers ring. The result was waiting … eight days. Because for more than a week, the Mercedes Concept Amg GT XX has been spinning without rest. The result is that at that time it has managed to complete the whole world. That is, 40,075 kilometers (24,901 miles). Specifically in 7 days, 13 hours 24 minutes and 7 seconds. Not happy with it, the car continued to pushing the barrier of 25,000 miles. On the way the Germans broke 25 long distance records. In the first 24 hours they already reached 5,479 kilometers. The figure was overwhelmed: 1,518 kilometers more tours than the previous record. The formula was simple and effective. Mercedes engineers mounted the pilot, he went to the track and put himself at a cruise speed of 300 km/h. When the battery was exhausted, passing through boxes to recharge at 850 kW of power. Thus, day and night. Day and night for eight days. In total, 3,177 turns of the Nardò circuit of 12.68 kilometers. You can consult all kilometer milestones (and also in miles) In this link. Among the keys that have allowed Mercedes get up with these distance recordsThe company ensures that cooling has been key. They say they have an innovative direct cooling system of the battery fluid. As the components have to face different temperature ranges, it has a central refrigerant concentrator that supplies the specific refrigeration that each of one of it needs. It is also connected to the main radiator and two other wheel arc radiators on each side of the front. Working surgically, you can distribute cooling among all components or specifically send it to the one you need most at that time. Thus, the test has been held in Three pillars: cooling, aerodynamics and recharges time. To guarantee the maximum performance, the company came to install its own medium voltage electric lines, transformers and load stations. Thus, they could have their own high -power load concentrator developed entirely by themselves. In fact, works that extended almost three months were necessary. The result: three loaders with a total power of 2.5 MW. The average of the charges was 850 kW but the company does not specify for how long they were carrying or to what percentage of the battery they loaded with each stop. It is impossible, therefore, to really know the battery capacity used. Photos | Mercedes In Xataka | Solid state batteries are the … Read more

Taking spectacular photographs of the Perseids seems impossible. NASA has a guide to demonstrate otherwise

by

The Perseids are already here and, although there are still a few days to reach their peak of activity, it is convenient to keep in mind some clues and tricks if our intention is to capture them in a photograph. Because as more than one will have proven, this is not always easy. AND Who better than NASA to point to any of these tricks. The first step: plan. If we want to get a good image of this rain of stars, the first thing is to think where and when. The Perseids or Tears of San Lorenzo can be seen for several weeks of summer, approximately between June 17 and August 24, and reach their peak of activity around August 11 and 12. Where and when it is also important when it comes to circumventing the great enemy of astrophotography: light pollution. First, it is convenient Avoid full moon And the phases in which it reflects the most light, since, although we do not perceive this light, it reduces the contrast that our eyes require to see the fleeting stars. It is also important flee from light pollution that generate the lights of cities and other settlements, so perhaps we should plan a trip to the field if we want to see these stars. Finally, we must also know where to look. Perseids owe their name that seem to radiate The constellation of Perseus. Knowing how to locating this constellation in the sky is very useful when restricting the angle to which to aim the objectives of our cameras and increase the probability of capturing some of these flashes. Second step: the team. A tripod can be helpful. Photography will require a long exposure. Maybe they are just a few seconds, but our pulse or any other involuntary movement could spoil a perfect shot. If we do not have a tripod we may resort to a “homemade” solution, such as supporting our camera on some rocks, but that will subtract maneuvering capacity. It can also be useful pertrech In order not to have the chamber trigger and thus avoid additional vibrations, but we can also dodge this requirement with the camera timer. Regarding the lens, NASA’s recommendation is in angular. Since we do not know when and where the next flash will happen, it will be best to cover a lot to increase our chances of success. Third step: Prepare. Once in position, we can start looking The constellation of Perseus. Orient our camera towards it will increase the chances of capturing the flashes of this rain of stars. The approach, best manual. The reason is that cameras self -effect systems can be lost in night darkness. Since we will not have to change the focal point, this does not imply any problem once we have taken the ideal approach. We will have, of course, to walk with an eye: sometimes focusing on infinity is not the best option, so it is a good idea to try small adjustments until you find the ideal approach. There is still a detail. We had said that capturing a rain of stars requires long exhibitions. Calculate how long can also require adjustments, but NASA also has a trick to facilitate work: Rule 500. It is about dividing 500 by the focal distance of the lens, and using the figure as time, in seconds, that our open shutter will remain. This value represents the maximum time that we can maintain the exposure before the terrestrial rotation makes the background stars begin to spread. If we have a 20 mm lens, we will have that 500/20 = 25 seconds of maximum. Experiment, enjoy. Rule 500 can be a good start, but we will still have to adjust our ISO and opening values, which will also allow us to play with shorter exhibitions. We can make small changes and verify how each one affects the quality of the image or its aesthetics. He last advice that NASA It has for those who are encouraged to photograph the persistes (or any other rain of stars) is simple: enjoy. These astronomical events offer us an opportunity to see the night sky in a different way, in advance generated by the unexpected flashes that cross the night sky on some summer nights.

Android does not have to be an absolute disaster in updates. Samsung has had to demonstrate it

by

Just a month ago Google updated its last pixel to the latest stable version of Android, 16. Today, in its presentation event of the Samsung Galaxy Z Fold7, Galaxy Z Flip7 and Galaxy Z Flip7 Fe, the company has presumed something unusual: the three have the latest version of Android. It is the two very clear points test in 2025. Android 16. That a manufacturer throws a phone with the latest version of Android just a month of its launch is very strange. Manufacturers usually take months and months to refine the ROM to the latest version, especially in cases such as Samsung, with a heavy customization layer. Laning three phones to the market with Android 16, when the Pixel are starting their journey with this version is a clear message: Samsung wants to be the first, and not only in speed. The seven years of updates. Samsung was the first to achieve something unusual: to advance Google in update policy. The manufacturer offers seven years of system updates and another seven years of security patches. Only Google (who arrived after Samsung) and Honor, who has joined the car, manage to offer their customers these figures on their best phones. Seven years of support are major words. It is not just the proof that Android phones They can update during the same time as an iPhoneIt is a trusted proof for the brand with respect to its own product. Leader in AI. Samsung has a Google partner to enhance his suite of artificial intelligence functions and, curiously, his Galaxy AI It is the most complete the AI ​​ecosystem in the mobile market. Above Google’s own proposal in his Pixel and far ahead of what rivals like Apple are doing. Samsung did not want to implement Gemini Nano To make the minimum effort: it has integrated its functions with the native apps of One UI, to the point where they are practically indistinguishable from any usual adjustment. Just press the AI ​​button to take a step further apps such as: Gallery Phone Circle to Search (compatible with S-PEN) Voice recorder Translator GENERATION OF WINDERS Third -party apps, such as WhatsApp and keyboard translation The lessons. For years, Touchwiz was the ugly duckling of the Roms on Android. Worked slow (there was lag) I was very overloaded with functions At the aesthetic level it was … debatable Today, it has one of the most refined ROMs at the interface level, it is able to manage all its native functions and apps without slowing down (even in mid -range and entrance mobiles) and is marking a path as a reference in updates and Ia.

China is attending a crazy race to demonstrate who has the safest battery. That’s why they crush them with tanks

by

If I point to the volume, I am not sure if I learned a lot or little in the university. But I am clear about one thing: I learned what was news or, at least, the criteria to point out whether an event is news. When the issues that can be discussed are put on a wording, different aspects are valued. Truthfulness, current, proximity … and novelty. And if an event comes out in the media it is because it is usually “unique, unpublished, unlikely or out of the ordinary.” I don’t say it, University institutions say. That is why it makes little sense to affirm that electric cars are dangerous based exclusively on news. We could do it if we had relevant studies that pointed out that the number of electric cars is notoriously higher than those of combustion. But it is not the case. We do know that the fire of an electric car is more complicated to turn off and more virulent. That is why it is logical that take action on ships where they are transported or working on New protocols in fire bodies. That does not mean that the risks of this technology are greater. In spite of everything, it also enters within a certain logic that when a fire is given or any other risk situation, the alarm voices are multiplied. From municipalities where They consider whether to continue buying electric cars a parking lots that prohibit their step. In that case, companies only have to show that their batteries are as safe as any other component of a car. As if I could pass them a tank over them. The crazy idea of ​​a tank Although it seems nonsense, it makes sense that manufacturers refine ideas when demonstrating the safety of electric car batteries. Keep in mind that, for example, In South Korea, an intense debate has been lived on whether or not these cars may accumulate in garages after A Mercedes Eqe will explode last year. When Byd arrived in Spain he had a challenge ahead. I needed to make themselves known and, above all, demonstrate that it was a company in which you could trust. We already know the prejudices towards the Chinese product. As a journalist, I don’t know how many times I could visualize This video in which a nail is going through an LFP battery without anything happening. It was one of the classic images. The other was the pressure tests. When too much pressure is applied to a battery (electric car or any other device) runs the risk of experimenting A thermal leak. Heat grows inside, chemistry is released and the pressure increases to cause an explosion with the consequent fire. To avoid this, the housings are designed to release the accumulated pressure inside, with the aim that if we have an accident, the pressure exerted on the battery does not cause an explosion. And the company can already tell us about figures and data and everything we want. But nothing better than the visual. Click on the image to go to the original tweet That is why Geely, explain in Carnewschina He has taken his new “Aegis Gold Brick Battery” a 36 -ton tank and has passed it over. And what happened? Nothing. Nothing at all. The battery did not give any sign of damage despite receiving 1.8 times the minimum pressure required by Chinese institutions to standardize a new battery. You can see the video on this link. They point out that the tank not only He crushed the battery On one occasion. He passed over it, returned on his steps and continued to crush her repeatedly. And did the same going over individual cells. The battery package “maintained its structural integrity without bulges, leaks, fires or explosions,” they emphasize. To overcome the test, the aegis Gold Brick Battery has been designed with a double wet coating that facilitates the dispersion of heat and thermal leaks since it is especially heat resistant to heat generated by aluminum oxide. It also has liquid-electrical separation of the materials. Photo | Geely In Xataka | Samsung has just revolutionized batteries for electric cars. In autonomy, in load time and in useful life

This 1,000 hp electric supercar is a wheel vacuum. And to demonstrate it they have put it to do the pine

by

“It is possibly one of the fastest cars that you have ever tried in curves. It is As if we had a magnet that hits the ground and allows curves to be made at speeds so unusual that even our body has to adapt. “ These are the words with which our partner Héctor Ares described the sensations transmitted by the Porsche Taycan In your first test. He described the electric car almost as one of those Scalextric cars to those who have not removed the magnet that sticks it to the raíl through which it circulates. This is because the Porsche Taycan uses what the German brand calls Porsche Active Aerodynamics (PAA)an active aerodynamic game in which the air is channeled through the low of the vehicle, is redirected where you want (brakes, for example) and next to the rear wing helps generate load. This load is the one that hits the car to the ground, which makes it especially fast in the curves. When a car has very little loadvery fast in a straight line circulates, it can reach very high speeds but In curve it is more unstable. When he has a lot of load, his advance is more difficult and needs greater power to reach the same speed. Instead, its passage through curve is very fast. In Icola, Formula 1 pilots use cars with a lot of aerodynamic load since the curves are constant. In Monza, on the contrary, cars with very little load are used because the lines are very long and the curves are relatively slow. Of course, they must fight with the famous parabolic of the end that puts a brake to convert cars into authentic rockets. But what happens when active aerodynamics is used is taken to the extreme? A car that is a vacuum cleaner To understand in a very simple way how active aerodynamics works, it is enough to observe the functioning of the DRS in Formula 1. A formula 1 car has an aerodynamic load selected by its engineers depending on the circuit in which it is going to compete. This takes into account, as we said, the curves and lines of the circuit. But when a pilot opens the DRS, the mobile part of the rear wing moves up. In this way, let more air pass, lose load (and resistance) and the car advances faster. When the pilot stops, the wing falls and has more load to pass the curve at a faster speed. Let’s say that has “more magnet” on the ground. In the 70s, active aerodynamics was prohibited in the competition but Colin Chapman took out an ace under his sleeve with the Brabham BT46b. He put a fan on his back, claiming that he served to cool the stressed engine. However, when it was launched, it generated a very strong aerodynamic load and allowed the car to a very high speed the curve. It was like a Scalextric car with a magnet. The McMurtry Spéirling putting face down That is what the McMurtry Spéirling. This electric car has become a sensation because combining the advantages of the electric car with a lightweight weight has managed to approach what we could expect from a rocket with wheels. This video in which the McMurtry Spéirling is seen removing the stickers to a Ferrari Laferrari already went viral. And it is that the electric one beats anyone because it manages to accelerate from 0 to 100 km/h in 1.4 seconds. A figure impossible to reach if it is not with an electric motor and a very deep management of traction control. It measures 3.5 meters long, 1.7 meters wide and 1.1 meters high and with its barely 1,000 kg of weight He takes out all possible performance to a 60 kWh battery. With her, she managed to get the record record to the Goodwood hill, a narrow circuit and that hinders the passage of speaking engines that need wider structures. See McMurtry Spéirling appear It is like seeing a vacuum cleaner working at full power. So much that to full performance it generates a deafening noise of 120 dB, something comparable to the take off from a plane seen 25 meters. But the truly striking, as our partners explain Motorpasion They are the 2,000 kg of load that it can generate. Given its weight content, those 2,000 kg of load allow you to make the pine. Its creators have wanted to demonstrate To what extent you can take performance to your system in a different way: sticking it to the roof. Boca down, the car generates so much aerodynamic load that can be kept without falling to the ground, only using its soil effect. He gets it because, just like Chapman’s invention in Formula 1, he has A turbine on demand. This Turbine sucks the air Under the car and stick it to the ground (in this case to the roof), which makes it keep upside down as if it had a magnet. It is the same as it costs to move more a full power vacuum than one or two degrees below. At the moment, we know that only 100 lucky ones can enjoy a car that recently beat the Top Gear circuit record in more than three seconds. A record that had Fernando Alonso’s Renault R24the car with which he ran in 2004 and that mounted a brutal v10 that also sounded spectacular … although different from this (yes, it can be said) aspirator with wheels.

Mathematicians needed 300 years to demonstrate Fermat’s last theorem. Computers have not achieved it

by

“I have found a really admirable demonstration, but the margin of the book is very small to put it.” It is what the 17th -century French mathematician Pierre de Fermat wrote when stating his His “last theorem”. Fermat’s problem took three decades to be found between the mathematician papers and three centuries until that admirable test was discovered. And yet the case is not entirely settled, only that the challenge is something different. Take it to a computer. He New challenge It is to make a computer to try the elusive theorem. That is the objective of a new project, FERMAT FORMALISINGled by Imperial College London. Fermat’s problem. Fermat’s last theorem “postulates that, if A, byc are natural numbers and not equal to zero, the an+bn = cn equation has no solution if n is greater than two. Formally demonstrating something is not as simple as trying it by rehearsal and error, and this demonstration, too complex for the “megish margin” of the Fermat’s notebook would be lost for centuries. The problem was resolved in 1994 by the British Andrew Wiles, who had begun to solve this puzzle with only 10 years. In 2016 Wiles was awarded the ABEL award, the award considered “The Nobel of Mathematics.” Almost one million pounds. Another 30 years after the resolution of the enigma and more than three centuries after the death of Fermat, a team of researchers, led by Kevin Buzzard, of Imperial College London, has put to work to take a different step, teach A computer to solve this problem. The new project It began at the end of 2024 and will last until 2029. It has a financing of just over 934,000 pounds and already begins to give some results, in the form of code fragments that are added to a Database in Github. What remains to be resolved.It can be contraintuitive, but this type of reasoning, which lead us to formally demonstrate mathematical theorems, are difficult to teach computers. Recently, Buzzard and other experts They explained the complexity of the matter to the French newspaper I monde. To begin with, we must take into account that the resolution of this theorem is complex, it is no accident that several generations of mathematics would turn the brains trying to find it. These mathematicians also had previous experience in the field of resolution of these types of problems. As Buzzard explained to the French newspaper, mathematicians have a base that allows them to “jump steps” when explaining the resolution to this problem. A computer, however, must start from scratch when building its own explanation for the matter. And all this, for what? “Fermat’s last theorem (…) has no applications, theoretical or practices, in the real world,” Buzzard pointed out A few months ago to the magazine New Scientist. So why so much effort to teach a computer to solve something we already resolved? The key here is not in the past but in the future. According to Explain the team at the head of the projectcomputers today can be used to attend mathematicians trying to solve problems such as demonstration of theorems, but there is an obstacle to materializing some forms of help. The problem, they point out, is that few mathematicians have focused on working with this software, so there are no tools that have the “definitions” used by mathematicians to solve these problems. Working on this problem should be used to create the necessary databases for solving similar problems in the future. In Xataka | We had more than a century trying to solve some mathematical problems.
