What is typical?



Is the Shelby cobra GT.350 the most typical car in the world? Or was that car the most common car in the world or even in the USA when it first time rolled out from the factory in 1965? That legendary car is back in production again. But the image portrays the 1965 model. The car is classic, but are those classics very often today?

Media is the place where the extraordinary is turning regular things. Typical news and articles are handling superlatives or something very extraordinary things. Things like the fastest aircraft, tallest buildings, and tallest trees fill all articles. When we are looking at media, we might think that regular people are misters or they are some kind of president. We might think that a regular Russian is Vladimir Putin. When we look at war movies we might think, that all U.S. soldiers are fighter pilots or some SEAL team members. 

We might think that a regular person in the western world is some kind of millionaire. If we look at car magazines we might think that all people are driving muscle cars. We might think that Shelby GT.350 is the most common car in the world. That car is over 50 years old. And maybe somebody put there the electric engine series. But otherwise, those cars are mainly in a museum or some movies. 

Is SR-71 a typical aircraft? That aircraft is well-known. But is it a typical U.S. aircraft, even in the military sector? 


So what is typical?


How good a question. The universe where we live is the only known universe in the third dimension. Because we don't know other universes, the universe where we are living is typical for us. Same way if we only see skyscrapers and we ever go out from an area where are skyscrapers we might think that skyscraper is the typical house where people are living. 

If we see only people who are similar to us, we might think that we are typical people. The thing is that we might think very extraordinary things very ordinary. When we are reading about things like scientific writing we might think that typical researchers are working with a Large Hadron accelerator in CERN. And typical physicists are working with some kind of Higgs boson research. 

Almost all published scientific stories about particles are connected with the Large Hadron collider and Higgs boson. But we can say that those things are not typical. They are the most high-energy particle and the most high-energy tools in physics. But the fact is that those superlatives are far away from the typical scientific tools. 

Same way if we think about the SR-71 "Blackbird" and the stories that are published about the fastest aircraft in the world we might think that the typical recon plane is some kind of SR-71. The fact is that the most unusual airplane in the world is not the SR-71 that is retired. 

Superlatives are fascinating things. They are always interesting. We might find the tallest tree in the world from the Guinness book of records or Wikipedia. 

That tree is Coastal redwood in California. But regular trees are a little bit shorter. But what if we spend our entire life in the forest where are only coastal redwoods? We might think that coastal redwoods are typical trees on our planet. 

So extraordinary fills most of the articles in the world. And that means we are facing one thing. Most of the articles and facts that are searched and written handle very extraordinary things.

The standardized probability variable and its role in the study



We are all heard of the standard probability variable. But many people do not know what this thing means. The "standard variable" means the criteria used for choosing the participants or actors for research. The ability to handle those variables is the thing that gives results to the researcher. 

When the researcher makes research. One of the key elements to getting real information out from research is to know what those "standard probability variables are". The researcher must know the research team's criteria for selecting the sample. That is under research. When researchers are researching things like viruses they must realize one thing. 

HIV infection makes all organisms dangerous for those patients. Same way. That is one version of the co-effect that boosts the effect of the primary variable. 

In COVID-19 statistics the primary variable is COVID-19. But co-variables ("booster variables") are HIV infection or weak immune defense. 

 If the patient uses an immune depressant. That makes all viruses dangerous for those people. Those medicals are causing chemical AIDS. And they are used with organ transplants to deny immune reactions. 


There are many ways to report deaths about COVID-19.


*Researcher can report all victims. That is dead during the pandemia and use the COVID-19 antigens as criteria. 


*In that case, we can say that if a person has a COVID-19 infection. And get under the car is dead because of COVID-19, which is not true. But if the criteria are only COVID-19 antigens the statistic shows that the person died because of COVID-19. 


*Researchers can report only cases that are dead because of COVID-19 infection. But in that case, we must check things like HIV infection.


*Researchers can also involve things like hospice or cancer therapy or the use of narcotics in those research. Or researchers can bypass those things, and that thing can affect results. 


How to select a sample is a problematic question. When we are thinking about the changes in the brain structure of COVID-19 patients, we must notice some other variables in the research. Those variables are lifestyles, use of alcohol, and use of narcotics. 

And many other things that can affect the metabolism and especially neuron metabolism. Those things are playing a key role in the co-effect of virus infections.

The political culture and use of power

The political culture and use of power

The thing is that democracy is a good way to rule the country if the decisions, what government makes are pleasing me, is a good way to think about things. This is the thing, what we must remember when we are talking about the way to rule the nation. If every people in the country supports the leaders, in every state, would have democracy. But why western democracies are supporting dictators?

This is a good question, and the thing is that dictatorial government are a good way to turn attention away from internal politics. If somebody goes worse than in our country, why people should complain? And if people would get too much salary, that thing means, that the production must transfer to some far-east countries, which are also suitable enemies for the western world, because they are far away from us.

Who cares about the conditions, where those people live, because of their national firewall denies the information, what comes from that country. And there are tales that western companies have delivered the firewall technology to those governments for denying the delivering the unpleasing information of the human rights in those countries. What people can't see does not exist is the idea of censorship. And that's why the benefit of some companies might be that people cannot see where those products or their materials are made.

Sooner or later every person in the world must tell the opinions about things like democracy and ruling the nation. This is the thing in every sector of life. Economic leaders must say, do they want to support the political systems, what are against the benefit of the nation and ordinary people.

When we are thinking about the reason, what many rulers have used when they are "forgotten" the next elections is that they are making their nation great. But then somebody would ask, what is the definition for the nation? If normal people are living below the limit of the poor, we must realize that there is something wrong with that state. When we are talking about the regular or average salaries of the state, we must realize that there are two ways to calculate those things.

One is that every salary type in the state would list in the line and that brings the average salary, what is a little bit different than the real economic situation in that nation. This way to make statistics is very impressive, but it is forgotten one thing, and that is how many people would get each class of salary. The thing is that the ruling class, which represents only a couple of percent of citizens can get billions of dollars, and the rest of the people are eating their shoes.

This is a provocative example of the thing, what is called as the growing difference between the incomes. But many times the GNP is mentioned the good method to tell the world, how wealthy the nation or its economy is. That thing tells about how much each nation would earn, and that thing is a really interesting number. When we are thinking about GNP that tells only how much the nation earns per citizen. But it would not tell who will get most of the money, and it would not tell, how much each nation pays to other countries.

This means that most of the national income might come from foreign companies and investors, which seems a very good thing. But then that nation can buy foreign military material and most of the income might go back to foreign hands.

Or otherwise, those states could sell their waterworks to foreign investors and then return all their money to foreign countries. Otherwise, GNP is not telling, who exactly is earning the money of some nations, and that means that the distribution of the incomings is not seen in the statistics, what is always telling about GNP. Another way to tell people is that the economic situation in the state is good is telling, how much or rather a way to say, what is the percent of unemployed people.

That thing is a very good meter about the competitiveness of the companies, which operates in some nation. But the thing, what is missing from those statistics is how many people are in pension, and the thing what would be nice to see is, has that country the way to handle unemployment just to put them in the pension or to works, where they don't get salaries? That thing is a really good way to make statistics looking good. If a person would not get a job, would that inmate send to some"institute" for retraining, and that's a good answer for many problems.

Bad economic situations somehow justify that companies are telling that they must decrease salaries, but the high percentage of unemployed people means that companies have the freedom to select workers freely because there are more offenders for jobs. And that will be a good way to keep people silent, because if somebody talks against the employer, would that mean, that the job of that person would be seen more careful than before.

If we are thinking about the one-party governments, the best thing, what those governments can hope is that people are making 12 hours working days. Too much free time makes possible to agitate against the government and it's a way to rule the nation, and also the long working day will keep people out from social media. That allows companies to deny the delivering information, which is not meant to tell for great public. The thing is that democracy is a good way to rule the country if the decisions, what government makes are pleasing me, is a good way to think about things, as I wrote at the beginning of this text.

How to make artificial intelligence, and why this kind of things are so hard to create in practice.



(Wikipedia)


How to make artificial intelligence, and why this kind of things are so hard to create in practice. 

Even the best artificial intelligence solution is only the large database, where are lots of actions recorded. And when the artificial intelligence needs to do something new, the new action must be programmed by a human operator. The making of the database would take an extremely long time if we want to create a sophisticated database, where are lots of answers in multiple problems. And making those solutions is very hard to create because every single action needs to program separately. When we are thinking about a chess computer, that program would just calculate an extremely large number of movements on the chessboard.

The thing is that on the chessboard is a limited number of possible movements and the computer must just calculate them all. That makes it effective. And then the programmer must find out, what is the most effective first movement and program that movement to the program. Then it can calculate every single movement and counter movement, what the opponent can make. And of course, the terms like "mate" and the strategic object of the game must be programmed.

This is the problem to create artificial intelligence. The thing that every each action must record to the database separately is taking time. The thing with this kind of artificial intelligence is that the creation of this kind of systems is similar work with making statistics. 

Statistics is an effective tool for finding out things like the political opinions of some group. The tools for statistical analysis are simple. Only thing, what is needed is Excel or some other similar program. But collecting the data to those sheets is the thing, what takes most of the work. The same thing is with the robot, which uses artificial intelligence. 

Every single movement must record to that robot separately, and of course, there must be found some connection with the command and some action. Let's take one simple example of that thing. If the programmer wants to teach commands like "take me a newspaper". The thing seems a very easy process. But when the programmer wants to make that thing, every part of the command must teach separately. 

When the actions for the command is described the creator must describe, what is the newspaper, where it can be found, and what to do if the newspaper is not found from that particular place? The thing is that if this part of the program, what is called " the error correction" is not made, the program can be locked or stoned because the event handler cannot find matches between the input, what is taken from sensors and the action, what is stored in a database. 

The teaching of the computer of the robot must happen by using the same method what is used with children, and the operator would use the command to console, and then walk with the robot to the place, and then make what should be done. And remember that "get" is the first part of the command. 

Then the next command would be the object, what must be taken. And then the action, what must be done after that. But if the robot would not find the newspaper, it can report that thing to the controller, and if the controller would say, look it from the table. 

This kind of command means that robot would search the table, what is in kitchen and if it would not still find it, that machine would go to the living room and then it would systematically search those things from every room and every table. The thing is that the order of those rooms and the layout of the house has been programmed in the memory of the robot. 

If we think that somewhere in Universe the robots, what are equipped with artificial intelligence would start to create a new civilization, we would think that maybe they would act like ants or wasps. They would create spacecraft, which also operates as the autonomous factor, what can create other robots. 

This particular unit will have the same role with the ant queen, and it would create a new base on the planet, what it can use as the same way as ants use their nest in nature. In some vision, the robot civilization would start to create city-looking structures when they are spreading across the universe. The purpose of the city would be to act as a trap for organic civilizations. The thing what computers need is the mind of the living organisms. The problem with the computer is that they are not able to create any abstractions. So they don't have imagination at all.

About behavior sciences

About behavior sciences

Behavior sciences or sharper to say cognitive behavioral sciences are one version of the psychoanalysis. The thing is that when the person is telling something, the observer follows the body language like pushing hands to ham, or rising voice to find out the thing, what is sensitive for the customer. In modern research, the researcher can use many technological tools for creating the profile.

One of those methods is using the sensors, what are collecting data from the blood pressure and central nervous system, to find out what kind of things are making the person nervous. But there are also many other methods to find out if a person has troubles with other people. One is of course statistics, and that method is a really good way to find out if the person, who is in some institute or prison has troubles with guards or other staff.

That thing is that the system collects data about things, how many times guard forgets to turn the clasp on the locked position when the prisoner is in the cell? Or how many times the director of the prison would accept or deny the holiday when prisoner would ask about it?  

The number of denies and accepted asks is comparing with the averages, what that person, who has made similar crimes would get. And that tells something about the relationship with that institute and prisoner. The statistics are telling us things, what we don't want to tell other people.

It tells how many time we would crash with car, or how many times the law enforcement is visiting in inmates home. Statistics are telling things like our lifestyle to other people. Statistics are telling if we would order food to our home, and it tells also if we would not order things like pizza. Maybe that would not tell things to normal people, but what if the person ever orders things like pizza to home?

The researcher would ask about why somebody ever orders pizza and the other thing what might be interesting is if the person takes a taxi, but drives to wrong address, and nobody seems with that inmate. What is the reason for that? Is there something, what that person wants to hide? Or what would you like inmate, who is always eating at a different restaurant? Is there some reason for that? The idea of the profile is to map that kind of things and find out reasons, why some person acts some way. And those things are very interesting to think when some interesting people are tracked from society.

The meaningless thing might have meaning




The meaningless thing might have meaning

The first in this text is taken in the old city in Tallinn, Estonia, and as you see, there seems to be something wrong, and the reason why I took this picture, is that the wooden house is in the very bad condition. So why the city authorities would not order to fix that house is interesting. The thing is that this kind of places is really expensive places to live, and why somebody would leave the house in that condition.

The other houses seem very good repaired and kept, and the thing is, why this house has gone in so bad condition? I think that the taxes should pay anyway, even if the house is not in use, but maybe there is some reason, why the owner doesn't care about that house, what locates in the historical city area.



The Gauss curve in the houses

The second image is portraying the Western Harbor of Helsinki, and the nice detail of this house or passenger terminal is the Gauss curve on the roof. This form is the same what the calculations of the averages would give in mathematics. The mean would give that form, and sometimes I have thought, why the form of the average curve is in this house?

Of course, the  Gauss curve is the beautiful form, and the thing is that the politicians need that curve, when they are calculating so-called average person. And the second thing, what the Gauss curve tells for the specialists is some test too easy or too difficult. In the normal scenario is that the test results would follow the graph of the average values, which means that if the real results are different from the Gauss curve, that thing means the test was too difficult or too easy.

If the number of failed is rising, the test would be too easy. And if the number of excellent results would be raised, the test was too easy. But when we are thinking the averages, we must realize, that we should compare the results of all places, where the test has been made, and if there is only one anomaly, that would mean that there is something different in the group, or somebody has been given the answers to a certain group. The last one would be very clear, but the investigator should think, why those results have been given to a certain group?

How probability influences to team spirit?

How probability influences to team spirit?

travellingintimeandspace.wordpress.com

The role of the player is important for a team playing

Here I'm writing about the statistics and problems of the roles in the team, and here I must say that during this writing I was really concerning that nobody sees any connections to real situations. This is the writing about the illusion, what statistics are making, and that means that the example of two players is purely fictional. But in my personal opinion that is a good example, what statistics make to the team.

When we are thinking about statistics, and how they influence the team spirit, we are facing problems, that there are many things that are making a good team, and the thing is that we need stars. But at the same time, we need people, who are building the game. And the last one is a very difficult person because that person is invisible in the statistics.

If you do this, you might make somebody very sad

The role in the team is given by the coach and would you rather be the invisible player, who would work in the silent role than the player, who has the opportunity to make points? I think that the role of the last one is more fascinating than the first one, and the coach would offer that thing to players, who have potential. And the sad thing is that there must be people, who have the role number one. The teamwork is important, but would you like to be played, who will ever make points?

Sometimes I have heard the story about the two players, what can play every team sports and the form of the story depends on the person, who tells you about this story of two players. This story is fictional, but it is used in the training of directors of companies. And it goes like this. There are two players, who can play ice hockey, football or every other team sports. Player number one is good game builder, that person shares the game tool, what is a ball or hockey, depending on the teller.

Invisible players are important 

That inmate works in the middle area and shares the tool for other people, and the result is that that person is the second server in every each point, what the team makes. Player number two makes two points but loses the game tool in many critical places, and that causes the many points to the opponents. So which one is better of those two players? The result is that this first player in invisible in statistics and that causes the illusion that the player number two is better because those points are visible in the statistics. The thing is that invisible players are also very important actors in the field of teamwork.

But how we could tell somebody, that this person would ever get the glory and cheers for the good work? Those things are also part of the motivation of people. And the thing is that those "silent players" motivation must be also good, and there is one big question and that is, "how we can recruit those silent hard working people to the team in the next year". Nobody wants to go home after the match and look at the mirror when other players are in the celebration ceremonies. This is a very big thing in sports and other team works.

Computer researchers published a new algorithm that revolutionizes web management.

The new database structures require new and powerful tools to manage databases in non-centralized solutions. The new data structures can be ...
