Until recently, scientists and writers could not agree on the subject of tears. In "Henry VI," Shakespeare wrote that "weeping softens the force of grief", and American author lemony Snicket said that everyone knows that a good, long portion Reva often does better, even if the circumstances haven't changed a bit. Charles Darwin, on the other hand, believed that the production of tears (that is, the act of prolonged crying) is just a useless side effect of work okoloplodnykh muscles. He believed that these muscles must from time to time be reduced so as not to overflow with blood; and the expulsion of tears was just the unintended consequence of this evolutionary physiological process.
He Also acknowledged that crying helps babies to attract the attention of their parents.
We Now know that crying — at least when you cry adults is a complex physiological response to some emotional stimulus. The most noticeable feature will, of course, shedding tears, but it also includes changes in the facial expressions and breathing patterns. Weeping, for example, refers to the rapid inhalation and exhalation of breath that often accompany crying.
From a scientific point of view, this cry differs from the outpouring of tears in response to chemical stimulus, for example when you accidentally rubbed into the eyes of something sharp. Even the tears are different. In 1981, a psychiatrist from Minnesota, William Frey II found that the tears caused by sad movies, contain more protein than tears that are shed when cutting onions.
Since all we ever listened to a Comedy gig or how the groom reads the wedding vows to his bride, emotional tears are not confined to melancholy. And although we all know what weeping and tears, happy and sad, why adults cry — is not very clear.
One of the ideas is that the cry of the adult is not much different from the crying of a child, if judged on its social nature. In other words, perhaps the crying is literally a call for attention, a way to enlist the support and assistance of our friends when we need them most of all. It is a way to inform our internal emotional state, when we cannot fully articulate.
Although this may explain some forms of crying, a lot of researchers found that adults often cry when they are all alone. Also tears can serve as a means of "secondary evaluation", helping people to realize how they are now frustrated to understand their own feelings. This idea is controversial, but some data support it.
And there is the concept of catharsis: crying, which is exempt from emotionally stressful situations. This idea would agree not only Shakespeare, but also the Roman poet Ovid, who wrote: "Crying is a relief, grief is satisfied and carried away by tears." The Greek philosopher Aristotle wrote that crying "cleanses the mind". In 1986, studying popular American magazines and Newspapers, one psychologist found that in 94% of articles on the theme of crying mentioned that it helps to relieve psychological stress.
In 2008, around 4,300 young people from 30 countries took part in the study, which showed that most of them feel mentally and physically better after crying, though not all. Some of them did not notice any change after a session of tears, some even said that they got worse.
The Difference seems to lie in the social context: if a person is embarrassed to cry in public, for example, he might feel less determination than when I cry alone or in the presence of a close friend. The study also says that when people try to suppress or hide his weeping, they also lose a sense of relief after that.
Thus, the phrase "a good cry" makes sense, but the tears were really effective, you need the correct social support. This means, ultimately, that adults can cry exactly for the same reasons that infants: in search of the help of friends and family.

According to a new study, one giant and distant world that was once described as "the planet that shouldn't be where she is" seems to have really formed, not where one would expect, and not from the outer material, which would have to be a part of and thanks to which are born almost all the known world.
the Laws of thermodynamics, which are the cornerstones of modern physics help us explain the behavior and change of the physical properties of objects and environments under certain conditions and circumstances.
