We live in interesting times - in the XXI century, technology subject to man and used everywhere, and in the scientific work, and at home.We study the surface of Mars and produced a set of wanting to settle down on the Red Planet.Meanwhile, today, there are a variety of natural phenomena, the mechanism of which is still not understood.These phenomena include ball lightning, which represents a genuine interest for scientists around the world.
first documented case of the emergence of ball lightning occurred in 1638 in England, in a church in the county of Devon.As a result of the excesses of the huge fireball killed 4 people, injured about 60. Subsequently, periodically there were new reports of similar phenomena, but they were few, as witnesses believed fireball illusion or deception of view.
first generalization of cases a unique natural phenomenon produced by the Frenchman F. Arago in the middle of the XIX century, his statistics collected about 30 certificates.The increasing number of such meetings has allowed to receive, based on the descriptions of witnesses, some of the characteristics inherent in the celestial visitor.
ball lightning - a phenomenon of the electric nature fireball moves into the air in an unpredictable direction, glowing, but not heat.This general properties ends and begins particular characteristic of each of the cases.
This is because the nature of ball lightning is not fully understood, because until now it was not possible to investigate this phenomenon in the laboratory or to recreate a model for study.In some cases, the diameter of the fireball is a few centimeters, sometimes reaching half a meter.
Photo fireballs fascinated by its beauty, but the impression is deceptively harmless optical illusion - many witnesses received injuries and burns, some became victims.This happened with Richmann physicist whose work on experiments during a thunderstorm ended in tragedy.
Lightning ball for several hundred years has been the object of study of many scientists, which included Tesla, GI Babat, Kapitza, Boris Smirnov, IP Stakhanov and others.Academics have put forward various theories of ball lightning, which number more than 200.
According to one version, the electromagnetic wave is formed between the ground and the clouds at some point reaches a critical amplitude and forms a spherical discharge gas.
Another version is that ball lightning consists of a high-density plasma and contains its own microwave radiation field.Some scientists believe that the phenomenon of the fireball - it is the result of focusing cosmic rays clouds.
Most cases of this phenomenon is fixed before the storm, and during thunderstorms, so the hypothesis is considered to be the most pressing energy-emergence of an enabling environment for the emergence of various plasma formations, one of which is lightning.
views of experts agree that the meeting with the heavenly guests must adhere to certain rules of conduct.The main thing - do not make any sudden movements, do not run away, try to minimize vibrations in the air.
