is it Possible to meet someone like you as two drops of water?
Have you ever Thought about the fact that somewhere on Earth there is a man, just exactly like you? He can dress differently, speak another language, to be a little older or younger. But under certain circumstances look pretty much the same as you. We often meet people, like our friends, even in one city. And nobody can exclude the fact that in different parts of our planet can live two identical a person's appearance. Who ever can meet. But what are the chances from a scientific point of view that this will happen?
According to the scientists, the existence of these twins (if not to take into account the twins) on Earth is extremely unlikely. Experts from Australia, has studied a variety of statistical data and determined the probability of the existence of two people with 8 identical facial features.
They found a small likelihood that there are a pair of twins — people, indistinguishable from each other. This value, if we take into account 8 features of the face, is one trillion. Fully the probability of the existence of twins cannot be excluded but, obviously, to meet a person like you as one drop of water to another, is almost impossible.
To reach this conclusion, a biologist Tegan Lucas from the University of Adelaide in Australia and her team studied 4 000 different individuals from the database of the U.S. armed forces. This is data that was created by the army to track physiological changes soldiers. Biologists have compared these people and tried to identify at least two with 8 General features. Though not told what features were used in the study.
The Team calculated that the likelihood that someone will look exactly the same as the other person is about one in a trillion. This means that there is a mathematical possibility of the existence of twins, but it is extremely unlikely.

The results of the study can be compared to "theorem about infinite monkeys". She argues that if the abstract monkey locked up in a room with a typewriter, then hitting randomly on a typewriter for an unlimited period of time, sooner or later the monkey will print any beforehand the given text.
If you think a monkey has one chance in 33 to correctly dial the first letter of "Idiot" Dostoevsky. It seems not so bad. However, the second letter, the probability is reduced to 1 to 1089 (33 x 33), and by the end of the fifth word (22 letters) — to one of five quintillion. When you multiply the probabilities at each other, the chances of happening are disappearing very quickly.
So why do people continue to tell you that he saw someone similar to you, if it's statistically unlikely?
The Problem here is that people are unable to perceive faces differently. Even if two people look different, people may perceive them as one, because the level of the brain they map the whole face, and not each of its individual features. This explains why many of us think identical twins look exactly the same, when in fact they usually have a lot of differences.
Cameron Howard Winklevoss and Tyler Howard Winklevoss, some of the authors ideas Facebook. Even twins have differences.
Although a person is not a true double of the other — we may think that this is because we are not able to determine the smallest measure his facial features, as did the team in their study. To some it may seem that there are a lot like each other, but in fact it is not.
In Other words, it is likely that you have a DoppelgangeR who, in the opinion of your friends looks exactly the same as you, but if you analyzed its characteristics from a scientific point of view, hardly would have received a 100% match.
A Group of scientists also believes that since the probability of finding a true twin of a person is extremely small, face recognition can be as a good tool, like fingerprinting or DNA matching with the search and capture of wanted criminals.
The Use of CCTV for security purposes is expanded to lie around more and more cases where criminals "Shine" their face on the crime scene — says Lucas. At the same time they try not to leave DNA or at the crime scene.

The Team demonstrated that using 8 facial features, she was able to accurately match the face captured on CCTV camera, with a real suspect. Probably why she did not disclose the method of his study is that criminals are unable to benefit fromdata.
Is all this good news. The likelihood that your double running around and committing crimes, impossible. Even if your friends or family might think you look the same.
