Expression twice in one river, meaning and meaning.

Some of these problems are developed in the magazine's case file. One of them proclaimed it as a metaphor: we can never pass twice in one river, because when we enter the second time, the river will change, it will not be the same. The only constant is change. However, today the change has changed.

We can say, without fear of being mistaken, that our concept of time has accelerated in our relations with us and with others. Throughout history, time has been one of the important variables in human relations, although it has not always been measured equally. Until the Middle Ages, no one cared to measure time in hours and minutes. At present, we can characterize our time in a nanosecond. This is a unit of time that is used in quantum physics, equivalent to one billionth of a second.

It seems that not enough time to measure with hours and seconds. We need to measure it in nanoseconds. Everything should be already and when it's too late. We have the impression that days pass at a nanosecond speed. Not realizing that this ends the year in which we had a lot of things that were canceled. The sensation of speed creates the paradox of creating impatience, making us feel that there is no time to achieve. Therefore, anxiety is one of the symptoms of our age.

This is what our subjectivity is built in a culture where acceleration is adequately consumed in the market of sale and purchase in which our society has transformed. No matter what is bought, what interests him. This can be an automatic spin, an accelerated yoga course, ten sessions for the treatment of a phobia or a psychotropic next generation. The main thing is not to stop. Do not stop at another. Do not cease to know our desire. Some will say: why stop, if there is a system that offers us everything we need.

In fact, this is a problem: we do not need what they offer us, but because they offer it, we need it. Writer Don Delillo begins this subjective acceleration of time in the nineties. This is a decade in which the hegemony of financial capital has been confirmed worldwide. This is a decade of unique thought about this so-called neoliberal capitalism. The goal was to make profit quickly and easily. The Internet has become a means for investing money through agencies listed on the stock exchange.

He quickly earned money and quickly lost money, sitting comfortably in front of a computer. Of course, when the virtual bubble exploded, few won and many lost. This speed culture encompasses many everyday relationships in which the permanent future is the only important one. In the postmodern perspective, history has come to an end. The past no longer matters. Everything is outdated and outdated. As Don Delillo says, we always need to go forward, never come back. Doubt arising from past experiences has been fixed.

His result - "invent a new theory of time." This is the amnesia of the future. However, a memory appears. What we do not want to remember interrupts our speed and stops us. Perhaps unconsciously, those who are excluded from this system have found a way: picket. Unoccupied workers cut the street or route and stop us. We want to get to the place, and we cannot. Some feel scared because they see a possible future in them. There is no sector in which the government wants to be more invisible than the social excluded.

Although there is always the opportunity to run forward. For this reason, nothing is better than remembering Albert Camus in a fragment of the book "Plague": Those who devoted themselves to plumbing equipment did not have much merit in this, knowing that this was the only thing left, and did not decide that it would be incredible . These teams helped our fellow citizens penetrate more deeply into the plague and partially convinced them that, since the disease was there, it was necessary to do what was necessary to combat it.

When the plague became the work of several, it was really seen as what it was, that is, everything. The famous phrase is attributed to Heraclitus of Ephesus: you can not swim twice in the same river. In any case, psychologists and neurologists agree or should coincide that our previous experience determines how we react to new situations presented to us.

Thus, when faced with a situation for the first time, it will affect how we face a similar situation in the future. And this is not due to anything other than the ability to adapt to change. This is what we call neural plasticity, the new property of the nervous system. And what is the use of plasticity?

Thanks to her, we are capable of the greatest feats, learn how to handle the streets of London, play the violin or become great circus performers. If you have ever traveled to London or have seen a movie or a series in the city where Sherlock was born, you will notice that one of his international icons are the so-called taxis, the famous retro-black cabs.

To obtain a license, you need to pass a sufficient number of tests to have your own name: Knowledge is good, the British can be quite dramatic in their own right, there is nothing more to see at their meetings in parliament. Such is the complexity of the street of the British capital, in which more than a thousand streets and thousands of landmarks, which usually takes from three to four years to pass the exam. This means that learning is so complicated that when we finish, we can say that they are no longer the same.

This is already a classic experiment in which Eleonora Maguire, a researcher at the neuroimaging center at University College London, used magnetic resonance scanners to study the brain of those who can absorb Knowledge. He found that those who passed the test had a larger hippocampus on the back. Those students of taxi drivers, who stayed the way, did not present changes in their brain structure. This music has a powerful influence on our brain - this is what we already talked about in these houses. But this is one thing that changes our brain structure.

To become a qualified musician obviously requires a lot of practice and good skills of perception, motor, organizational, memory, etc. recently, all this training has been shown to cause changes in the brain. Several areas related to hearing, mainly in the temporal lobe, are more developed in professional musicians than people who have not learned to play the instrument, even being 10 times larger. In addition, the changes brought about by musical education are not only structural, but also functional.

That is, not only brain areas are developed, but also better connected with each other. Another interesting question is how professional musicians achieve such mastery of their instruments. For example, it was shown that musicians playing stringed instruments have a large area of ​​the brain designed to control the movement of the fingers, suggesting that the brain adapts in a plastic way depending on how we use our body. This is not comparable with the skill that the violinist achieves with his own hands, to the control that the dancer achieves of her own body.

From the ballet of Moscow to the Circus of the Sun in the dance there is something magnetic that hypnotizes us and makes us dream like children. In the end, it seems supernatural for all of us that a person can take his body to the extreme and even surpass it. And, of course, it would be rare if no researcher had seen the show and decided what was happening in the minds of these connoisseurs of physical labor.

They found that this type of practice causes an increase in the areas of the brain responsible for perception of movement. In addition, these changes persist for several months, even if you stop practicing. And not only in this type of activity, a later study evaluated others, such as meditation, finding similar results. With an 11-hour training program for 4 weeks, researchers at the University of Oxford found that brain connections between areas that help us control care are strengthened.

These results are consistent with previous research, in which it is clear that meditation has a positive effect on various psychological functions, such as memory, learning, decision making, etc. As Sergio Garcia Morilla explained in his blog.

And how do all these changes occur? This is not so clear. There are several hypotheses, since partial data were found in different directions. For example, it has recently been shown that dendritic spikes, areas where neurons connect to each other, increase after one hour of motor training in rats. That is, in a very short time, neurons can change their efficiency in order to more easily connect with each other. However, such rapid changes are not enough to support learning, it is also necessary to achieve slower, but long-term changes.

Otherwise, we will soon forget, because to save things we need changes that will be more resistant to interference and forgetfulness. In this direction, other researchers have focused on the study of, for example, how stem cells become new neurons in order to establish appropriate connections to reflect what we learn. This process takes several months, so it can be associated with this way of keeping learning in our memory for a longer time.

Thus, between rapid adaptation and lasting changes, the brain is constantly changing as a result of learning, learning and experience. Not only when we are children, but throughout our lives, we do not cease to change. Thus, there is still hope: it is never too late to learn to play an instrument or dance, because it is not only a pleasant personal experience, but it changes us inside and prepares us for future situations with more resources within our reach.
