Is humanity getting dumber?

Shot from the movie "Dumb and Dumberer: When Harry Met Lloyd"

For most of human history, people have become smarter. But now the opposite is true. If in the past the average IQ score increased, now everything is going in the opposite direction and people are getting dumber. 

You just don’t think – this is not a judgment, but a fact: in many leading countries, IQ indicators began to decline. And at this very time, technology is becoming smarter. Creepy, right? But it really gets scary from the fact that there are many scientific studies confirming that humanity is rapidly becoming stupid. Moreover, scientists seriously fear for our common future. Does this really mean that idiocracy – the degradation of the world’s population due to the rapid deterioration of people’s mental abilities – is inevitable?

The film “Dumb and Dumber” shows what life can be like for people of the future. 
No kidding

An IQ test or intelligence test measures parameters such as spatial thinking, vocabulary size, the ability to abstract mind-sets, and classify information.

Were people smarter in the past?

According to the famous psychologist James Flynn, a huge number of factors affect our intellectual abilities – from air quality to choosing a life partner. Also, do not underestimate the influence of random factors – as the BBC Future writes , even a job loss or personal tragedy can negatively affect the level of intelligence. Moreover, researchers agree that in general about 80% of adult intelligence is predetermined by genes.

Flynn, a professor at New Zealand University of Otago, is seriously concerned about the future of mankind. The professor is convinced that the views of the younger generation on current problems are too superficial, which leaves much room for manipulation of their consciousness by politicians and the media. However, in general, the scientist looks at the situation positively. The fact is that in the first half of the twentieth century, Flynn discovered an obvious increase in IQ indicators. This effect is called the Flynn effect. But if we really got smarter half a century ago, then what happens today?

People are getting stupid at the same pace as they used to get smarter

According to the results of an already famous study of scientists from the Norwegian Ragnar Frisch Center for Economic Research, the level of intelligence today drops by an average of seven points in ten years. In the course of their work, the researchers analyzed the 730,000 IQ tests that Norwegian men underwent before compulsory military service from 1970 to 2009.

If this trend continues – and the study has been severely criticized because of the limited sample – after about 10 generations, the IQ level will drop from 130 (“very high”) to 69 (“extremely low”). But there is even more frightening news – experts found that every decade IQ fell by 1.23 points. This means that over the course of a century and a half, the overall decline has already reached 14 points. It is noteworthy that what is happening there are many potential explanations, ranging from environmental issues and the quality of food, ending with the lack of exercise and a long stay at the computer.

Do you alos having problems understand what is written on the board? 
What does that say about you?

The forecast of scientists is not at all comforting: if this continues further, then in the not too distant future, a person in his mental abilities will approach a … developed monkey.

No less exciting are the results of another study, this time larger. A few years ago, an international team of scientists wanted to test the level of education of modern people and residents of the Victorian era from 1837 to 1901. The conclusions were not comforting – about a century and a half ago, people were much more developed and inventive.

Scientists came to such conclusions after evaluating the reaction rate – in 1889, the reaction rate of men was 183 milliseconds, but men of the 21st century react to external stimuli at a speed of 253 milliseconds. For women, everything is about the same – instead of 188 milliseconds in the 19th century, the reaction rate dropped to the 261st millisecond. Such slowness and inhibition, as the researchers note, is a weak coefficient of intelligence in humans.

Unfortunately, Flynn today admits that IQ growth in the 20th century has staggered. A number of studies using a variety of well-established IQ tests and metrics have revealed declines in Scandinavia, the UK, Germany, France and Australia. Details vary from research to research and from place to place. But the overall picture has become much clearer: since the 21st century, many of the most economically developed countries have faced a decline in IQ.

Well, reverse evolution is evolution too!

Are we waiting for idiocy?

As in the film “Idiocracy”, the assumption that the average intelligence of mankind is reduced due to the fact that families with lower IQ have more children (dysgenic fertility) has been repeatedly expressed. However, a study conducted in Norway in 2018 showed that IQ falls not only in different societies, but also in families. Even children born to parents with high IQ roll down the IQ ladder. Some environmental factor — or a combination of factors — causes a decrease in the IQ of parents and their own children, as well as older children and their younger brothers and sisters.

In the end, it will be great if we can determine the exact reason for the decline in IQ before we finally go stupid. By the way, the fact that everyone sets new temperature records – and heat reduces mental abilities by as much as 13% – also does not add optimism. One way or another, the problem really exists and requires the attention of researchers around the world. Especially in view of the threats that climate change poses to the world.

Japan has developed an inflatable scooter that weighs practically nothing

The University of Tokyo engineers have developed the Poimo inflatable electric scooter, which is created individually for each owner. It is enough to send your photo to the manufacturers – and a personal optimized model will be assembled for you.

The scooter is designed with a special program for the body size of a particular user and his specific fit. Moreover, each owner is free to make any changes to this model. If he makes any changes to the drawing, the program will automatically redesign the electric bike to maintain its strength, stability and controllability. When the model is finished and approved, it is handed over to the manufacturer.

Scooter Poimo

The scooter consists of seven separate inflatable sections that are constructed from durable fabric and sewn with straight stitch. It remains to add electronic components – in particular, a brushless motor and a lithium-ion battery. 

The finished electric scooter weighs about 9 kg and can travel at speeds up to 6 km / h (that is, slightly faster than a pedestrian). It can work for an hour on one charge.

This is how the current version of Poimo looks like in action:

Excerpts from Elon Musk’s speech at the Martian Society convention

Elon Musk’s comments with questions relayed from the Mars Society Membership by Dr. Robert Zubrin, James L. Burk, and Carie Fay. Following Elon’s 30 min time, Dr. Zubrin took additional questions. This special event was part of the 2020 Mars Society Virtual Convention from October 14-18, 2020.

About Starship Test Schedule:

– entering orbit – with a probability of 80% -90% will take place in 2021

– the probability of the return of the ship and the 1st stage in this flight is 50%

– test of refueling in orbit – 2022

– Starship lunar version – 2022 or 2023

– Starship flight to Mars – around 2024

The goal of the Starship is to build a self-sufficient settlement on Mars as quickly as possible. Musk does not rule out the possibility that this will not be achieved during his lifetime. According to his rough estimates, to create a self-sufficient city, it will be necessary to deliver 1 million tons of cargo, which corresponds to 4-5 million tons in a low Earth orbit. Modern single-use launch vehicles are capable of removing less than 1% of this value.

“Disposable launch vehicles are completely stupid. They are a waste of time. I think people need to stop wasting time on this. If you try to sell a disposable plane, you will be thrown out of the office. If you try to sell a disposable car, you will also be thrown out of the office. “

A series of questions and answers followed:

What is the best landing site on Mars?

– I’m not sure about that. But I can name the criteria. The first of these is latitude: most likely it will be in the northern hemisphere, far enough to the north to have water ice, but to still have enough sunlight.It also needs to be low to get the most benefit from atmospheric braking.

How do you prioritize mission priorities: research, infrastructure construction, and science?

– The first will be the construction of a fuel plant.

A question from a teenager who wants to become an engineer and robot maker with a dream to work at SpaceX: what is the most important education in order to become an engineer?

– There are many varieties of this profession: you can be an aerospace engineer, in the field of electronics, software, or a chemical engineer involved in creating safe production of fuels. I think physics is a good foundation for critical thinking.

Boring Company was originally conceived as a tunnel manufacturing firm on Mars?

– No. It was originally something of a joke. I thought tunnels were a good solution to reduce the traffic problem in cities and improve the quality of life by turning parking lots into green parks. To do this, you need to go to 3d [get away from the “flat” infrastructure – approx. per.]. I think tunnels are good for Mars too. But there you need a lot lighter equipment: you don’t care about mass on Earth, but you will have to take care of it a lot when going to Mars.

At Boring Company, have you learned a lot of technology that might come in handy on Mars?

– I think, yes.

Do you have any tips for young people who love Mars but don’t know how to participate in its settlement?

– I think any strong advocate of the need to conquer Mars matters. People often don’t even think about it. I often talk to people who don’t even know about it. Therefore, I consider it important for humanity and consciousness in general to bring a discussion about this to society. Talking about it with friends and acquaintances – I think this is what we should do. In my estimate, we will spend less than 1% of our efforts on Mars exploration, exactly less than healthcare, perhaps even less than cosmetics – this will be enough to make life multi-planetary. But this requires people to start talking about it 100 times more often. I think this is what really matters. [the entire cosmonautics of the world is $ 424 billion a year, while cosmetics is $ 532 billion, and tobacco production is $ 849 billion – approx. per.]

What’s the coolest part about Starship development?

– I think the coolest detail is the ability to work with a great group of engineers and come up with interesting solutions. I think the best thing is the opportunity to work with smart and creative people who come up with solutions that were not available before. This is a great reward.

What do you focus on when hiring, especially with regard to engineers?

“We’re looking for signs of exceptional ability. Or at the very least, striving to do exceptional things at SpaceX.

Are you planning to make a Mars-Earth communication system like Starlink?

– Yes, I think we will use a laser, probably launched into orbit, to avoid atmospheric diffraction. Thus, it will be a laser beam going from the orbit of the Earth to the orbit of Mars. And also relay satellites in solar orbit, since the laser beam cannot be sent through the Sun [when it is between Mars and Earth – approx. per.].

Can Starship be used for other destinations like Venus and other planets?

– Starship will be able to travel to any target in the solar system that has a solid surface when fuel depots appear. It is not the kind of transport that will take us to other stars, but when we become a multi-planetary species, we will create a demand for innovation in space travel that will ultimately lead us to interstellar travel.

Cern Scientists Plan an Impressive Experiment – They Will Come Into A Parallel Universe

Cern scientists are once again preparing to impress the entire planet and become the focus of discussions with the new experiment they are planning.

An experiment that, if it brings the fascinating result that scientists have in mind,  will change the way we think about the world , will take place in the next few days at the Large Hadron Collider, the European nuclear center, Geneva CERN Research.

The astonishingly LHC complex, the largest, most energetic elemental accelerator in the world,  will be “fired” for the first time to its highest energy levels, in an effort to detect – or even create – tiny black holes. 

If it succeeds, then, a completely new universe will be revealed – rewriting not only the books of physics, but also the books of philosophy! 

It is possible, however,  that gravity from our universe will “leak” into this parallel universe, as LHC scientists say. 

From the Higgs boson to dark matter and the parallel universe

According to the British Express, the experiment is sure to “trigger” the critics, who are worried about the LHC, many of whom warn that the elementary particle accelerator will mark the end of our universe, creating a of the black hole.

Nevertheless,  Geneva has remained … intact since 2008, when the LHC began its spectacular “work”.

The first scientists at the Large Hadron Collider proved the existence of the Higgs boson – a key building block of the universe – and the LHC appears to be on track to locate “dark matter” – a previously undetectable force now considered that it constitutes the majority of matter in the universe, being, in fact, the reason why the latter is constantly expanding and moving away. 

So next week’s experiment is considered to change the game. 

The truth is out there

Mir Faizal, one of three heads of the three natural groups behind the experiment, said: 

“Like many parallel sheets, which are two-dimensional objects (width and length) can exist in a third dimension (height) , so parallel universes can also exist in higher dimensions. We anticipate that gravity can leak into extra dimensions, and if that happens, then tiny black holes can be produced in the LHC. 

Normally, when people think of the multiverse, they think of the interpretation of quantum mechanics by many worlds, where every possibility is realized. This cannot be tested and so it is a philosophy and not a science. We do not mean this with parallel universes. What we mean is real universes, in extra dimensions. The truth is out there.”
