If the Internet type in the Google search bar phrase "perpetual motion with their hands", the search engine is very helpfully displays an impressive number (over 75,000) of different results, including pictures, videos and detailed instructions to the work of existing models.Though attempts to repeat the "success" of the plurality of authors at home invariably ends in complete failure, this once again confirms the stubbornness inherent in human nature, which does not give the man to put up with the action of immutable laws of nature and makes him look inexhaustible sources of unlimited energy.
In the history of the perpetual motion machine was first mentioned in a poem by the Indian astronomer, mathematician and poet Bhaskara, which dates back to around 1150 so that India can rightly be regarded as the ancestral home of the first models of perpetuum mobile.This poem describes a perpetual motion machine in the form of a wheel with fixed slanting rim narrow, long vessels, which is half filled with mercury.The difference in the moments of gravity, which was created to move in fluid vessels, should have made the wheel is constantly rotating.But circumvent the laws of nature could not.
Since human imagination constantly leads to new ideas.However, instead of the simple mechanics of modern inventors are now offering to use electricity, magnetic or gravitational force.For example, a magnetic perpetual motion involves placing a circle of small magnets and their effects on the magnetic field of the magnet is located separately.According to the plan, and the attraction of repulsion of like opposite poles of the magnets should make the wheel spin without any outside interference.But in reality this does not happen, or else long ago everyone in the apartment was similar to the unit.
It turns out that, no matter how willing people, a perpetual motion machine of any, even the most complex design contains flaws and is not working.And all because the principle of its operation violates the first or second law of thermodynamics.
In 1775, more than two centuries ago, in Western Europe against the belief in the existence of perpetual motion was made by the most authoritative scientific tribunal that time - the Paris Academy of Sciences.Already at that time, many prominent scientists have led a lot of conclusive evidence of the impossibility of perpetual motion.Around the middle of the twentieth century recognized this fact exhausted by endless requests of the United States Patent Office.
However, still there are people who say they have invented another model of perpetual motion.As a rule, scam artists who are trying to cash in on the credulity and ignorance of the laws of thermodynamics.However, it is possible that among these people will have a new genius who did come up with an eco-friendly compact engine capable of extracting energy from the world around us in such quantities and with such a long life of work, that it can be called "eternal".
