Prypjat (50,000 inhabitants) ex pearl technological and social Soviet Union, for over two decades is immense reduced to ghost town, in the background the plant that caused the disaster.
Some German artists with the help of a guide have designed these "shadows" in the abandoned homes, most of the dead were children, now playing in the city were only shadows.
The evacuation took place very late (well one day and a half later), when the sirens started to ring people have left the city immediately, for many it was already too late.
These kittens were born within a 30Km more contamination, are almost all blind and destined to death.
Some people do not have another place to go have never abandoned their land, ignoring the provisions have continued to cultivate vegetables and fish in the river, most of them died during the first five years. This lady has lost her husband and remained alone in the company of his cats, the only assistance that the state provides to these people is the periodic survey of the level of radioactivity. Within a radius of 60Km do not live more than forty people, most are elderly.
Even today there are many cases of people who suddenly fall ill because of radiation, this little girl is called Victoria and went into hospital for a wound to the leg that is not healed. After several days of hospitalization the immune system has finally ceased to function, the appetite has disappeared and the body began to fill the spots. The hospital in Kiev is not a center of excellence for these cases, the family of Victoria to economic problems has not had a chance to take it abroad.
(3 July 2005, hospital Kiev)
The nuclear contamination is an invisible killer that leaves no escape, the levels of radioactivity in the area make their lives impossible. The four reactor was shut down in a sarcophagus of concrete and steel, Geiger counters, however, continue to talk about death. Here radiation is seventy times higher than the acceptable threshold, you can not stay in for more than a few minutes.
Blog is also a video that helps to have a more clear idea of the situation, some few years courageous even give you guided tours.

More or less all as kids we enjoyed disassemble objects, moved by curiosity and armed with a screwdriver past the hour to look into things trying to understand the operation. This ability is called reverse engineering, requires understanding the logic and mathematical knowledge, no other life forms in addition to human beings able to use it. The exponential growth of scientific knowledge has allowed us over time to disassemble building ever more complex, even today we know what's inside an atom, what are the laws that govern it.
Thanks to "push" of progress in medical and military for decades, we can peek inside one of the most complex machines designed by the brain. The brain is the computer center available to most forms of life evolved, fueled by electrical impulses deals dell'eleborazione of information coming from outside. Its structure is not particularly complex, monkeys are divided into two hemispheres, each hemisphere contains N areas each with its own specific task, the loss of an area does not affect the operation of the system, the core consists of mirror neurons. This jewel of engineering can produce electricity needed for its operation simply by combining oxygen and sugar, disperses very little heat but needs a constant temperature to function perfectly.
The scientific community agrees on one thing: to understand the functioning of the brain is among the most dangerous things we do. The hypothesis most likely to get even prophesy the gradual disappearance of homo sapiens, successful of singularity technology by 2050.
For the moment the areas of development are more advanced than the vision bionics and control implants, cybernetic eyes are now able to talk to the brain and restore sight to those who lost, artificial limbs directly controlled by the nervous system patient can return normal life to those who have suffered amputations.
The scientists fear more than anything else concerns the strengthening of mirror neurons (the central processor), an increase in computing power, the arrival of cybernetics external memories, all steps that would lead to the birth of a new species. However one should be our choice not an extinction (the same thing that they thought the monkeys a few thousand years ago?), In each case the first to earn the compliments should be good Nietzsche could have understood the mechanism with a lot advance .

October 1st, 2008 - Posted in mathematics, science, video | Slow-motion pretty much shows that the mathematical structure produced by a steel ball falling in the sand. The deep bond that binds our reality mathematics is too often underestimated, the majority of people prefer to take refuge in simple answers, models illogical that are good for everyone. By now everyone knows that under our planet there is no Atlas hard to sustain the burden with the sweat of the front, however, still views the world rather ridiculous compared to the subtlety of logic.
The story of Logos is very old, anticipates the legends related to Christianity 520 years but in reality has little to do with the novels. To explain in the simplest way possible what is necessary to first understand who they are human beings. Wishing to avoid unnecessary philosophical sproloqui can safely say that homo sapiens is an animal, all shaved and perfumed but always part of the fauna. Having said that the remains undeniable difference between a homo sapiens and any other animal, it is clear that mankind has something more, what it is not clear to many is whether this "surplus" derives from the resemblance to a god or the ability to understand math. Only those who know mathematics can make music, only those who know mathematics can go into space, only those who know mathematics can evolve in a way so fast in 200 years to double its life cycle. Human beings are a lot with technology, according to scientists dispogono of "computing power" from about 15,000 years, although this trend with a discontinuous and in the process of acceleration (Kurzweil's Law), all thanks to mathematics.
It is not easy to determine who was the first human being to realize the existence of Logos, the starting point is perhaps to be found in Pythagoras and his school.
"The whole world is harmony and number"
Pythagoras unfortunately did not have a good opinion of the people, the school pitagorica required that the lessons remain secret and the oral tradition was privileged, not wrote virtually nothing, some historians have argued that Pythagoras become the power of mathematics decided to keep secret cult to prevent mankind blinded by the power coming to make a bad use (without anything mathematics military technology). Worshiped odd numbers (finite, closed, perfect) and 10 considered as sacred (his depiction points for a draw was the famous "tetraktys"). They were the subject of numerous attacks of the political class and forced to disperse brought knowledge with them.
Galileo Galilei had pretty clear ideas about the forces that surrounded the church not liked:
"The philosophy is written in this great book that we are continually open before our eyes, but we can not think before they learn to mean the language and know the characters, or what is written. He is written in language mathematics, and the characters are triangles, circles and other geometric figures, without which means it is impossible to understand human speech, without them is a wandering in vain for a dark laberinto. "
Leonardo DaVinci instead was the first to give a practical demonstration of the existence of the "structure" of Logos in nature, with brilliant mind and his hand as the only genius anticipated by several centuries studies in those areas where we launch, had understood that all the "science" were linked by a single logic, he left traces everywhere especially in designs but also in a few sentences scattered codes:
"I do not see who is not in my mathematical principles"
"Nobody is in effect nature sanza reason, plan to reason and you do not need experience."
"Nature is obliged by virtue of his law, which she infused lives."
"The proportion not only in numbers and measures fia found, but etiam on in the sounds, weights, times and locations, and 'n enhances whatever it is."
I could go on but I think they have reached the goal of these things today are written many books but still do not have the necessary prominence to science, it is easier to replace old clothes cute white idiocy that shoot from a balcony, does not matter if people take vaneggi senile for scientific truth, indeed perhaps the goal is just that today as centuries ago.
The inspiration for this article came from the phrase that Walter Veltroni spoke yesterday at the conference on "secularism 'in Italy - Democracy and religion":
"Religion can not 'be relegated to a private space: you can not' think of leaving it outside the door"
Ualter people are tired of being taken to the anus imaginary friends try to understand, the church no longer controls 99.9% of like 60 years ago, is consumed unnecessary language licking!
September 30th, 2008 - Posted in nature, science, video | The SpaceX's Falcon 1 is the first space launch made entirely of private, took place on September 28 at 04:15 pm, a huge step, especially for the cost of launches that until recently could only be sustained by large agencies space. The video contains the entire launch until positioning satellite.
September 29th, 2008 - Posted in science, video | Alzheimer's is a degenerative process that causes the death of brain cells (neurons), usually appears after the age of 60 and effect more visible is the progressive loss of memory in the short term. This spot helps to understand a very simple example which could be the feelings surrounding this type of pathology.
September 26th, 2008 - Posted in science, video | Video very useful to help you understand what size may have some planets and stars. The largest are supernovae (dying stars) consistency of gas compared to these giants the land looks like a poor stone.
