If you read every day, you live longer! It has been scientifically proven

A study called "Achapter a day: Pair of reading books with longevity", conducted on a sample of over 3,500 people reveals that people who read books at least 30 minutes every day, live longer than those who do not read at all.

According to The Guardian, the study, published in the journal "Social Science & Medicine" analyzed patterns of reading 3,635 people, aged at least 50 years. On average, readers of books live nearly two years longer than people who do not read.

Respondents were divided into three categories: those who read 3.5 hours or more per week, those who read up to 3.5 hours per week and those who do not read, being considered factors such as sex, race and education .




Researchers have discovered over 12 years (the study), those who read the more chances of death were 23% lower, while those who read moderately lower by 17%.

Overall, throughout the study, 33% of those who died were reading, compared with 27% of readers, according to the researchers Avni Bavishi, Becca Levy and Martin Slade School of Public Health at Yale University.

"When readers are compared with non-readers in the mortality rate of 80%, non-readers have experienced 85 months (7.08 years), whereas experienced readers 108 months (9.00 years). Therefore, reading provided a survival advantage of 23 months, "write the researchers in the study. Bavishi said that prolonged consumption of literature has a higher yield, but "even 30 minutes a day are beneficial in terms of survival."

The paper also associate reading books rather than magazines, with longevity.

"We found that reading novels provides a greater benefit than reading newspapers or magazines. We realized that this effect is because a book involves more human mind, offering cognitive benefits, thus increasing life," he said Bavishi.

In the study, scientists have noted that there are two cognitive processes involved in reading, which creates a "survival advantage". First, reading promotes "slow process, captivating read deep" cognitive engagement "appears while the reader make connections with material things, finds applicability in the real world and ask questions about the content presented."

"The involvement may explain why cognitive vocabulary, raţionaamentul, concentration and critical thinking skills are improved by exposure to books," the researchers stressed.

Secondly, the books "promotes empathy, social perception, emotional intelligence - cognitive processes that lead to better survival."

Although respondents did not specify the kind of literature read, according to the study, most likely they read fiction. Academics suggest that analyzes future could check "if there are other benefits from reading outside of longevity, if any similar effects after reading eBooks or audio that could be read in a manner less sedentary and if different types of cards generates different effects. "

Experts have concluded that "the benefits of reading books - longevity, especially - is not only interesting characters and ideas found in novels, but more time to read."

A team of American researchers has discovered a new type of ... fire. Experts have said that ,, blue spiral "that identified it is similar to those formed during tornadoes and that it could be used to create clean fuel, but also to clean oil films emerging in seas and oceans from accidental spills.

Turns are made up of a core of fire, around which air columns appear invisible to the naked eye. The phenomena of this type occur naturally during fires and strong winds and because the burning fuel efficiency, could be used to clean up oil spilled in the waters of seas and oceans.

During an experiment, a team of researchers from the University of Maryland simulated in the laboratory how to produce oil spills, positioning above the water half-cylinder of quartz to create fire whirls. At that time, scientists have found that vortex that I was provoked into a whirl of yellow and blue color first suggesting the presence of soot particles and the second draft fuel combustion process.



Scientists have said that the second color of the flame is the most important because it indicates that the carbon dioxide released is much smaller than in a normal combustion.

Although the claim that the gap formed between the flame and the surface entails maintaining fire can tell researchers do not know yet why he burned this way: ,, Normally, a coil of fire is turbulent, but it is very quiet and stable, without showing visible or audible signs of turbulence. It is an intriguing discovery, which offers numerous possibilities both inside and outside the laboratory, "says Xiao Huahua, one of the team of investigation.

Scientists have proposed to carry out the experiment and their research outside the lab. In this regard, the experts are expected to use fire turns to clean oil from the surface of seas and oceans occurred during discharge. Moreover, scientists discovered the phenomenon say that will help them better understand the mechanics of fluids.

Scientists convert carbon dioxide to create electricity


This graphic explains novel method for capturing the greenhouse gas and converting it to a useful product -- while producing electrical energy.

While the human race will always leave its carbon footprint on the Earth, it must continue to find ways to lessen the impact of its fossil fuel consumption.

"Carbon capture" technologies -- chemically trapping carbon dioxide before it is released into the atmosphere -- is one approach. In a recent study, Cornell University researchers disclose a novel method for capturing the greenhouse gas and converting it to a useful product -- while producing electrical energy.

System to convert carbon dioxide into electricity and hydrogen source: Computing




Lynden Archer, the James A. Friend Family Distinguished Professor of Engineering, and doctoral student Wajdi Al Sadat have developed an oxygen-assisted aluminum/carbon dioxide power cell that uses electrochemical reactions to both sequester the carbon dioxide and produce electricity.

Their paper, "The O2-assisted Al/CO2 electrochemical cell: A system for CO2 capture/conversion and electric power generation," was published July 20 in Science Advances.


The group's proposed cell would use aluminum as the anode and mixed streams of carbon dioxide and oxygen as the active ingredients of the cathode. The electrochemical reactions between the anode and the cathode would sequester the carbon dioxide into carbon-rich compounds while also producing electricity and a valuable oxalate as a byproduct.

In most current carbon-capture models, the carbon is captured in fluids or solids, which are then heated or depressurized to release the carbon dioxide. The concentrated gas must then be compressed and transported to industries able to reuse it, or sequestered underground. The findings in the study represent a possible paradigm shift, Archer said.

Carbon sequestration - Wikipedia


"The fact that we've designed a carbon capture technology that also generates electricity is, in and of itself, important," he said. "One of the roadblocks to adopting current carbon dioxide capture technology in electric power plants is that the regeneration of the fluids used for capturing carbon dioxide utilize as much as 25 percent of the energy output of the plant. This seriously limits commercial viability of such technology. Additionally, the captured carbon dioxide must be transported to sites where it can be sequestered or reused, which requires new infrastructure."

The group reported that their electrochemical cell generated 13 ampere hours per gram of porous carbon (as the cathode) at a discharge potential of around 1.4 volts. The energy produced by the cell is comparable to that produced by the highest energy-density battery systems.

Another key aspect of their findings, Archer says, is in the generation of superoxide intermediates, which are formed when the dioxide is reduced at the cathode. The superoxide reacts with the normally inert carbon dioxide, forming a carbon-carbon oxalate that is widely used in many industries, including pharmaceutical, fiber and metal smelting.

"A process able to convert carbon dioxide into a more reactive molecule such as an oxalate that contains two carbons opens up a cascade of reaction processes that can be used to synthesize a variety of products," Archer said, noting that the configuration of the electrochemical cell will be dependent on the product one chooses to make from the oxalate.

Al Sadat, who worked on onboard carbon capture vehicles at Saudi Aramco, said this technology in not limited to power-plant applications. "It fits really well with onboard capture in vehicles," he said, "especially if you think of an internal combustion engine and an auxiliary system that relies on electrical power."

He said aluminum is the perfect anode for this cell, as it is plentiful, safer than other high-energy density metals and lower in cost than other potential materials (lithium, sodium) while having comparable energy density to lithium. He added that many aluminum plants are already incorporating some sort of power-generation facility into their operations, so this technology could assist in both power generation and reducing carbon emissions.


A current drawback of this technology is that the electrolyte -- the liquid connecting the anode to the cathode -- is extremely sensitive to water. Ongoing work is addressing the performance of electrochemical systems and the use of electrolytes that are less water-sensitive.

The discovery that changes everything about the human brain "Cartographers of the Brain"






















Updated: 28/04/2020

The new map will help scientists better understand the new unknown areas of the human brain.

A team of researchers created the most detailed map of the human brain, skull radiographs using more than 100 people, to identify nearly 100 new regions of the cerebral cortex.

The new map defines 180 cortical areas, which helps scientists to understand better how we think, talk or feel, giving them new information about conditions such as autism, schizophrenia and dementia.




,, The brain is like a computer that can support any operating system and can run any software, "said neurologist David Van Essen, the University School of Medicine, St. Louis, Washington.

,, In fact, the operation mode is related to the structure of the brain. If you want to know what the brain can do, you should know as organized and connected, '' added the American scientist.

To build the map, the researchers used information from the Human Connectome project, a study was conducted long-term and consisted in the creation of over 1,200 radiographs of young adults with a custom MRI.


World Science Festival Cartographers of the Brain


Information in this group, the researchers examined radiographs of 210 people, men and women. The radiographs were recorded measurements of the participants' cerebral cortex, the area that controls memory, thinking, speaking and consciousness.

Volunteers brain was scanned at rest and when the participant carry light loads, to be able to measure brain activity effectively.

By using an algorithm specially developed by researchers at Oxford University in Britain, scientists were able to identify distinct parts of the brain.

To ensure that the results are correct, scientists compared them with those obtained from investigations made on another group of 210 people.

Over 180 new regions were discovered in each of the two hemispheres of the brain. 83 have been identified in previous research, and other 97 new zones have been identified in the new study.

,, There is a clear distinction between new parts discovered. In fact, the transition is gradual, indicating a mixture  and coordination between different sensory modalities and cognitive domains, "said the scientists.


Neurology:  poststroke cognitive impairment


Some regions are more understandable than others. One of the regions 55b is activated when we hear a story being related to language. Other researchers, however, are new and hard to understand, because some areas are related to many functions of the brain, which mean it takes a long time until specialists can understand the whole map of the brain.

Quantum computer simulates hydrogen molecule




A prototype quantum computer has been used to calculate the electronic structure of a hydrogen molecule for the first time, demonstrating the possibility of performing complex quantum-mechanical simulations of molecular processes on such devices.


Updated 02/05/2020

The quantum computer was constructed by researchers at Google’s research laboratories in California, US. Together with colleagues elsewhere in the US and in the UK, a team led by John Martinis used the device to perform electronic structure calculations that they say can be readily scaled up to more complex cases.1


IBM BrandVoice: The Quantum Computing Era Is Here. Why It Matters Forbes


The possibility of simulating quantum systems without the approximations necessary with classical computers was what prompted Richard Feynman to propose quantum computing back in 1982. As quantum computers have come closer to reality, much of the attention has been focused on the greater speed they should achieve relative to classical devices. But some feel that quantum simulation will end up being the ‘killer application’ that makes the effort worthwhile.


Roche - Quantum computers - Calculating the unimaginable


This is not the first time that a quantum-chemistry algorithm has been implemented on a proto-quantum computer. But previous efforts have not been able to exploit the full advantages of a quantum-based approach, because they have required costly ‘pre-computation’ steps on a classical computer, which limits the degree of complexity that can be handled this way. ’What is new here is that this work uses a scalable quantum computing architecture,’ says Matthias Troyer of the Swiss Federal Institute of Technology in Zurich, who was not involved in the research.


A combined approach

Google’s digital quantum computer uses superconducting devices for its quantum bits (qubits), in which information can be encoded in the quantum states of the supercurrent.2 To carry out the electronic structure calculation for a hydrogen molecule, the researchers used two different methods, called the variational quantum eigensolver (VQE) and phase-estimation algorithm (PEA).


Wired Google's Quantum Victory Is a Huge Deal—and a Letdown


‘We might soon see quantum computers that outperform classical ones for certain problems’‘Both are efficient quantum algorithms for finding ground-state energies,’ says team member Peter O’Malley, ‘but they take different approaches and have different advantages and disadvantages.’ The PEA method can in principle get the answer with arbitrary precision, but only if there are no errors in the process.

In practice errors are always present, in which case the VQE method works better. This involves using a series of successive algorithms that gradually improve on an initial guess at the molecule’s wavefunction. By adjusting the parameters in the wavefunction, it is possible to compensate for errors incurred in the computational steps and still get an answer – for the dissociation energy, say – essentially the same as that obtained from a detailed classical simulation of the molecule.



The researchers say that it is already possible to simulate more complicated molecules than hydrogen with their device. ‘The benefit of quantum simulation is that you only need a quantum simulator roughly the size of the molecule you want to simulate,’ says O’Malley. The calculation used only a third of the available qubits, and the team is now building quantum chips that should be able to model small transition-metal complexes.


‘All of these problems are still trivial and the effort of just controlling the quantum computer is still much more than that of solving the problem classically,’ says Troyer. He adds that we may soon see quantum computers that outperform classical ones for certain problems, but that doing quantum-chemistry calculations beyond the power of classical computers will take a few years longer.

The Future Is Now : First Flying Car Is Finally Here AEROMOBIL 3.0























It seems like Henry Ford, the chairman of Ford Motor Company was right all along. He was the first person to state that in the future years a unique innovation of flying cars will come into reality. And with so many tries and disappointments in the past, finally this dream has become true with the creation of the aeromobil 3.0. Today, we have the first flying car for sale in 2016.

Hold on to your seatbelts people, the news is true. Aeromobil has finally succeeded in creating a combination of a motorcar and airplane. What was first only seen in movies and in music videos, in the coming years will become something that’s extremely common. The fun part is perhaps in the future, people won’t even remember the effort they had to put in creating such a difficult and unique innovation.


Aeromobil, the company states that the vehicle has now been finalized and has been in flight-testing programs for safety and real flight conditions for approximately 3 months now. However, before we begin talking about the first flying car, let’s first take a look at the evolution of flying cars and the history of aeromobil, the company itself.






















THE HISTORY OF AEROMOBIL

Aeromobil is a road-able aircraft manufacturer company in Slovakia, which has been in the business of creating a combination of an automobile and aircraft for the past 26 years. The company first introduced its flying automobile in 1994 known as the AeroMobil 1.0. The vehicle wasn’t exactly able to fly, but is one of the first airplane-automobile ever created.

The company began with the creation of the AeroMobil 1.0 in the year 1990. So, it took exactly 4 years to develop. Nevertheless, once created the Aeromobil soon gained in popularity, due to its unique and alien-type design. It looks less like a car and more of an airplane, but required many upgrades and improvements to fly successfully.

This is where the company began working on the AeroMobil 2.0 in 1995 which continued all the way to 2010. This model of the flying car had much better design and looked futuristic, due to which it was able to gain more popularity than its predecessor. However, even so the vehicle wasn’t able to fly successfully and was rather small for a person to properly fit inside.

Next, after introducing the second version, Aeromobil went on creating the Aeromobil 2.5 in 2010. This airplane-automobile took almost 3 years to develop successfully and was a pre-prototype of the Aeromobil 3.0. Design wise, the company pulled off on giving the airplane-automobile a little more car-type look.

The 2.5 was a rather successful model of the Aeromobil and was accustomed to road traffic and could fly as a plane and land at any airport. It could also easily fit in any standard parking space. However, the company still felt that the vehicle needed a little more personal touch and has to make the whole transportation more sustainable, exciting, and efficient. Therefore, the company then started its work on the 3.0.




















Soon after gaining a lot of success from the Aeromobil 2.5, the company began creating the 3.0 in 2014. The vehicle took almost 10 months to develop and is perhaps the best looking airplane-automobile ever created. In fact, the vehicle makes for a good transformer! It shifts from an automobile to an airplane within just a few seconds.

Not only does the vehicle have an incredibly sport design, but from the rear it looks exactly like an airplane. Therefore, it is safe to say the company has pulled off the look of an airplane-automobile quite successfully. The vehicle is built from advanced composite material, making it incredibly strong and durable.

AeroMobil: Flying Car AeroMobil


That includes the wheels, wings, and body shell. Additionally, the vehicle comes equipped with various automobile safety features as well as airplane features, such as advanced parachute deployment system, autopilot, and avionics equipment. The vehicle also implements various other advanced technologies that will surely blow your mind.

One of these advanced technologies includes the variable angle of attack of the wings. This unique feature allows the vehicle to shorten the take-off requirements. The flexible and sturdy suspension also seems to be incredibly amazing like never seen before. It allows the vehicle to land and take-off even in rough terrain.




















As a plane, the AeroMobil 3.0 can be landed and used in any airport around the world and as a vehicle it can be driven in road traffic, use regular unleaded gasoline, and fit into standard parking spaces. To understand more, let’s take a look at the specification of the vehicle:

Aeromobil’s Flying Car 3.0 comes equipped with a Rotax 912 engine, which allows the vehicle to fly as well as drive on the open roads. The wings are collapsible and just like a convertible where the rooftop descends and ascends, the winds open out and close with just a push of a button. As an airplane, the engine allows the vehicle to reach speeds over 124mph. On the other hand, as an automobile the vehicle can reach speeds over 99mph.

AeroMobil reveals 5.0 flying taxi

For the vehicle to take-off successfully, only a speed of  81mph is required and can travel almost 435 miles in air without giving trouble and 545 miles on the road. The airplane has an overall fuel consumption of 15l/h and the automobile is capable of giving 100km in just 8 liters. It is built with carbon coating and steel framework.

As an airplane, the vehicle has an overall width of 8320mm and length of 6000mm, whereas, in drive-mode the vehicle has an overall length of 6000mm and width of 2240mm. the vehicle can seat up to 2 passengers, which is rather impressive for the first flying vehicle. According to recent studies, the Aeromobil 3.0 will be the first flying car for sale in 2016



If you think all of this is a hoax, it actually isn’t. Here’s video evidence that the dream of a flying car has now become reality:

Finally Solar Probe Plus (2018) will begin the Journey Into The Sun


Credit: NASA/Johns Hopkins University Applied Physics Laboratory 


After 60 years of dreaming of a close-up solar mission, it's quickly approaching time for NASA to realize that goal. Last week, the agency announced that the Solar Probe Plus mission has moved into "advanced development" ahead of a launch in 2018. It's being built by the Johns Hopkins University Applied Physics Laboratory (JHUAPL).

RELATED: Magnetic 'Braids' May Cook the Sun

Solar Probe Plus has an exciting few years ahead of it following the launch, including no less than seven (!) Venus flybys and a daring plunge into the corona, or the outer atmosphere of the sun. Here are some of the science details for you to brush up on:

Key elements of the solar probe plus mission of NASA


1. Staring down the Sun

Where does the sun's energy flow? How is the outer atmosphere heated? These are some of the main questions that NASA's Solar Probe Plus will answer. The microphone drp will happen when the probe gets the chance to fly through the solar corona, something scientists have wanted to do for 60 years but couldn't until the technology caught up. "Solar Probe Plus is a true mission of exploration; for example, the spacecraft will go close enough to the Sun to watch the solar wind speed from subsonic to supersonic, and it will fly ghrough the birthplace of the highest-energy solar particles," JHUAPL wrote on the mission website. "Still, as with any great mission of discovery, Solar Probe Plus is likely to generate more questions than it answers."


It's very common for spacecraft to use gravity assists to reduce their fuel requirements (which saves on launch weight and therefore money). But the tradeoff for Solar Probe Plus will be time as it flies seven times by the planet Venus between 2018 and 2024. It's only after the seventh flyby that Solar Probe Plus will be close enough to the sun to do all of the science that researchers desire. That said, the spacecraft will not be idle during this time. You can bet it will be looking at the star from afar, and that when it flies by Venus at least some science instruments will be turned on to look at the planet. It's like a bonus Venus mission.

Solar Probe Plus will need to withstand a lot of heat when it gets up close to the sun. It's closest approach is expected at 3.7 million miles (5.9 million kilometers), about seven times closer than Mercury ever gets to the sun. This also handily beats the record set by the Helios 2 spacecraft, which really just grazed the inside of Mercury's orbit. It passed about 27 million miles (44 million kilometers) from the sun in Apirl 1976. From both close up and afar, it will look at the solar wind (the stream of particles from the sun). energy transfer through the sun , and something called "dusty plasma" — superheated gas with suspended particles in it — near the sun.



The sun has a lot of mysteries surrounding its magnetic field. The main one is why the sun reverses olarity every 11 years in a cycle which sees it go from a weakling with pracically no sunspots, to a monster spewing solar flares, and back to a weakling again before switching polariteis once more. 

A bit part of the Solar Probe Plus mission is to probe the magnetic field and other parts of the sun to make better prediction sabout when the next flare will head towrads Earth. Big-enough solar flares can cause damage to satellites and even power lines. This image from the Solar Dynamics Observatory shows just how complicated the magnetic field is. "The complex overlay of lines can teach scientists about the wyas the sun's magnetism changes in response to the constant movemetn on and inside the sun," NASA wrote in March. "Note how the magnetic fields are densest near the bright spots visible on the sun — which are magnetically strong active regions — and many of the field lines link one active region to another."


If you're going to get close to the sun for long periods of time, you have to make sure your spacecraft can take the heat. Solar Probe Plus will carry a huge shield that is eight fee in diameter and 4.5 inches thick, made up of carbon-carbon carbon foam. Its solar arrays, JHUAPL said, will move around to make sure that the panels maintain the proper heat and power, retracting and extending as required. 

Some "heat-resistant technologies," JHUAPL added, came from NASA's MESSENGER spacecraft, a Mercury probe that flew by the planet three times before settling into an orbital mission that ran between 2011 and 2015. For example, the solar shield on Solar Probe Plus is similar toe designs of MESSENGER's sunshade.

Frightful mysteries of ancient mummies were untied with X-ray scans




















Updated 04/05/2020

Scientists have conducted a new study to see if some of the most popular myths about mummies or not a grain of truth.

"Mummification was practiced in Egypt for more than 3,000 years, and the practice was changed in different times and places. In the past, we have looked at one, two mummies and we get a conclusion, but now we have much more technology nondestructive and a wealth of medical information that we rely on, "said anthropologist Andrew Wade, from the University of Western Ontario.

In the next issue of the Journal of Archaeological Science, Wade and his teammate Andrew Nelson examined radiographs of a total of 84 mummies in museums around the world. Their goal was to approve or disapprove some of the oldest and strangest information on ancient mummies. This information was and that during mummification, rulers and their successors brains were removed through the nose. Another information is so that internal organs were removed from the rich mummies.

Journal of Archaeological Science: Reports - Elsevier

Mexico News Daily Guanajuato's beautiful and terrifying mummies
























Following our analysis based on X-ray scans, it was found that the mummification process was more complicated than we imagine.

Part of the blame for this confusion Greek historian Herodotus gate which noted in 440 BCE a description of the mummification process, following a visit to Thebes. Then he wrote that during the mummification of the rich is made interventions to remove the internal organs and the brain. Instead, for the poor, who were buried without being wrapped in cloth, resorting to a cheap technique of dissolving parts.


Ancient Egypt How were mummies made?. Herodotus




















"In fact, it seems that Tut's time, almost everyone could afford to be mummified," says Wade after analyzing mummies. Then Pharaoh Tutankhamen died around 1323 î.e.n, long before Herodotus, and after the death of Pharaoh, mummification became increasingly popular.

But sometimes things were happening and as described by Herodotus. For example, if the priest Nesperennub, looked at the British Museum with the help of a CT performance, it was found that during the mummification process and has been removed brain through the nostrils, and his organs, such as lungs were stored in containers.



Nesperennub Mummipedia Wiki

However, other times, not performed in accordance with mummification Herodotus. Sometimes the lungs and other organs were left inside mummies, and the brains were removed only in certain cases. Moreover, there were cases where, for removing the brain was a hole in the place where the spine meets the head.

On the other hand they were discovered instances where the mummy's head was filled with resin, and scientists explain this by suggesting that it is possible that golden hue liquid resin to be associated with the sun and divinity. However, the brain was not receiving significant attention at the time. Instead, it was observed that the length of cloth used to wrap the deceased's head vary significantly from case to case, depending on who achieve process. Following investigations it was found that in some cases, are used for head and 55 meters of cloth.


Moreover, the study does not find evidence concerning what Herodotus describes as inexpensive technique which would have involved the use of cedar oil to dissolve the entrails of the mummy. Scientists believe that the substance would be too expensive for such use. Instead, they say for embalming animals would be used turpentine (liquid obtained by distilling pine resin). Therefore, it is possible that Herodotus to be confused with the animal conservation method used for humans.

A practice that seems to have been reserved for the elite is linked to heart organ which was the center of conscience and morality in Egyptian mythology. "The whole idea was you could enjoy the afterlife, and certainly for this you needed heart," said Wade.



However, the analysis indicated a significant lack of heart among mummies, which suggests that keeping the body in the afterlife was reserved for the elite. As the "Book of the Dead" is prohibited sharing secrets related to the procedure of mummification, Wade speculate that it could have that common people do not even have been aware of the fact that they remove the heart to allow them to of a privileged elite. Moreover, all heart, the confection shaped stone jewelry beetles that lived over organ.

The 50 biggest inventions and innovations that changed the history of mankind






Of course, everyone has his opinion in this regard, but it would be interesting to find out what they think about it people who, for decades, working on technologies of all sorts, learning about technology - and teach others - students of evolution technologies throughout history? US publication The Atlantic took the initiative to gather a group of 12 experts - scientists, engineers, historians, businessmen - and ask them to draw each a list of 25 inventions or innovations that consider the more important. The only condition was that made those successes are inventing rear wheel, which occurred around now. 6000 years and so important for the further development of technology and human civilization in general, that the wheel has come to symbolize the collective mentality, the invention itself, the revolutionary idea that fundamentally changed the universe technological until then and give an impetus unprecedented progress. Here are the results of this exciting exercise, which give us an idea of ​​how people understand the world and its evolution - the world past, present and even the next.

Analyzing lists provided by participants, weighing the value for each individual inventions or innovations, based on their order, James Fallows, author of the article in The Atlantic, synthesized information in a more comprehensive list - 50 victories technological considered the most significant in history. The list is obviously far from exhaustive: as he says himself, to draw up a list of (only) 50 such successful means to exclude from the list another 50,000. Countless are the inventions and innovations that changed the life of humanity, and 50 of them - in the hundreds of thousands of years of evolution - it seems less. But just as limited and inevitably subjective, the result is no less interesting. Here is the list enriched with comments and author of some of the 12 experts who were asked to participate in the project.

1. The Pattern, 1430

Nominated for 10 of the 12 participants, the invention of printing with moveable type in Europe XV century, allowed easy and cheap access to knowledge, thus enriching and its rapid spread.



2. Electricity, late nineteenth century.


Modern life is unimaginable without it: countless other inventions would never have occurred if it were not first electricity as an energy source available to everyone.





3. Penicillin 1928

This first synthetic antibiotic manufactured by man opened a new era in medicine: once incurable diseases became easily curable thanks to antibiotics.








4. Electronic equipment semiconductor mid-twentieth century

They are the physical foundation of the virtual world; without them, we would not have had the means of mass communication we have today.







5, Optical lenses, XIII century



Because of them could have invented the microscope and telescope lenses contribution to human progress but not limited to that. Glasses, for example, were a huge factor of progress: As the author says, they have increased people's IQ, significantly increasing the number of those who could (or could learn) to read and write.





6. Paper, Century II

Support of writing and images, it contributed decisively to diseminaraea information and increase the number of literate people.










7. The internal combustion engine, the end of the century. XIX

It replaced the flute how great steam engine, being smaller and more efficient than it





8. Vaccination, 1796

This year, the British physician Edward Jenner developed an early form of vaccination using a virus disease of cattle; inoculated to humans, he restrained them from smallpox (infection by a related virus), a disfiguring disease and high mortality. But vaccinating gained momentum only since 1885, when Louis Pasteur invented the vaccine against rabies (rabies).







9. Internet, 1960

Missing from this list many other victories of science and technology, which others can would be included; GPS systems, which depend so much today transport and communications; the concept of the number zero on one of the participants, Padmasree Warrior, Director of Technology and Strategy at Cisco, he has proposed, moreover, on his own list, and more ...

Another point worth stressing is ... ambivalent character, say, of many of these inventions / innovations: can do both good and bad. Sometimes their negative side does not show from the beginning, but becomes evident over time. "If you look at antibiotics, insecticides, transportation - every time you solve a problem, see either us," says Joel Mokyr.

But this creates - is not it? - A permanent need solutions that stimulate the emergence of new and new inventions and innovations. It's called progress.
